phase4 - AS4 client and server

Logo

Build Status javadoc Maven Central

A library to send and receive AS4 messages. Licensed under the Apache 2 License!

It consists of the following sub-projects:

  • phase4-lib - basic data structures for AS4 handling, sending and receiving
  • phase4-profile-cef - AS4 profile for CEF/eSENS as well as the PMode and the respective validation
  • phase4-profile-peppol - AS4 profile for Peppol as well as the PMode and the respective validation (since v0.9.1)
  • phase4-test - integration test project
  • phase4-server-webapp - Standalone AS4 server for demo purposes
  • phase4-dynamic-discovery - a shared library that contains common stuff for dynamic discovery using SML and SMP (since 0.10.6)
  • phase4-peppol-client - a specific client to send messages to Peppol (since v0.9.3)
  • phase4-peppol-servlet - a specific servlet that can be used to receive messages from Peppol (since v0.9.7)
  • phase4-peppol-server-webapp - a simple standalone Peppol AS4 server for demo purposes (since v0.9.9)
  • phase4-cef-client - a specific client to send messages using the CEF profile (since v0.9.15)

This solution is CEF compliant. See the test report at https://ec.europa.eu/cefdigital/wiki/download/attachments/82773297/phase4%20AS4%20test%20runs.zip?version=1&modificationDate=1565683321725&api=v2

This solution is Peppol compliant. See the test report at https://github.com/phax/phase4/blob/master/docs/Peppol/TestBedReport-POP000306-20190906T103327.pdf

Configuration

The configuration part was reworked for 0.11.0 version.

The primary configuration file for phase4 is called phase4.properties. It contains both the phase4 specific configuration items as well as the WSS4J ones (see https://ws.apache.org/wss4j/config.html). The resolution of the configuration properties is not bound to the configuration file - system properties and environment variables can also be used. See https://github.com/phax/ph-commons#ph-config for details. Upon resolution of configuration values, Java system properties have the highest priority (400), before environment variables (300), the file phase4.properties (203), the file private-application.json (195), the file private-application.properties (190), the file application.json (185), the file application.properties (180) and finally the file reference.properties (1).

Note: prior to v0.11.0 a file called crypto.properties may have contained the keystore and truststore parameters used by phase4. Since v0.11.0 all these parameters are now exclusively read from phase4.properties.

Note: programmatic access to the configuration is solely achieved via class com.helger.phase4.config.AS4Configuration.

WSS4J properties

Note: the descriptions and the default values are taken from WSS4J.

  • org.apache.wss4j.crypto.provider: WSS4J specific provider used to create Crypto instances. Defaults to org.apache.wss4j.common.crypto.Merlin.

  • org.apache.wss4j.crypto.merlin.keystore.type: the keystore type. Usually one of JKS or PKCS12. Defaults to java.security.KeyStore.getDefaultType().

  • org.apache.wss4j.crypto.merlin.keystore.file: the path to the keystore. Can be an entry in the class path, a URL or an absolute file path.

  • org.apache.wss4j.crypto.merlin.keystore.password: the password to the whole keystore.

  • org.apache.wss4j.crypto.merlin.keystore.alias: the alias of the key to be used inside the keystore. Hint case sensitivity may be important here.

  • org.apache.wss4j.crypto.merlin.keystore.private.password: the password to access the key only. May be different from the keystore password.

  • org.apache.wss4j.crypto.merlin.load.cacerts: Whether or not to load the CA certificates in ${java.home}/lib/security/cacerts (default is false).

  • org.apache.wss4j.crypto.merlin.truststore.provider: The provider used to load truststores. By default it’s the same as the keystore provider. Set to an empty value to force use of the JRE’s default provider.

  • org.apache.wss4j.crypto.merlin.truststore.type: The truststore type. Usually one of JKS or PKCS12. Defaults to java.security.KeyStore.getDefaultType().

  • org.apache.wss4j.crypto.merlin.truststore.file: The location of the truststore. Can be an entry in the class path, a URL or an absolute file path.

  • org.apache.wss4j.crypto.merlin.truststore.password: The truststore password. Defaults to changeit.

Note: for Peppol users the key store must contain the AccessPoint private key and the truststore must contain the Peppol truststore.

phase4 properties

The properties have the following meaning

  • global.debug: enable or disable the global debugging mode in the system. It is recommended to have this always set to false except you are developing with the components. Valid values are true and false (prior 0.11.0 this property was called server.debug).

  • global.production: enable or disable the global production mode in the system. It is recommended to have this set to true when running an instance in a production like environment to improve performance and limit internal checks. Valid values are true and false (prior 0.11.0 this property was called server.production).

  • global.nostartupinfo: disable the logging of certain internals upon server startup when set to true. Valid values are true and false (prior 0.11.0 this property was called server.nostartupinfo).

  • global.datapath: the writable directory where the server stores data. It is recommended to be an absolute path (starting with /). The default value is the relative directory conf (prior 0.11.0 this property was called server.datapath).

  • phase4.manager.inmemory (since 0.11.0): if this property is set to true than phase4 will not create persistent data for PModes ands other domain objects. Since 0.11.0 the default value is true (prior versions used false as the default)

  • phase4.wss4j.syncsecurity (since 0.11.0): if this property is set to true all signing, encryption, signature verification and decryption is linearized in an artificial lock. This should help working around the https://issues.apache.org/jira/browse/WSS-660 bug if one Java runtime needs to contain multiple instances of phase4. Note: this flag is still experimental. Note: this is only a work-around if only phase4 based applications run in the same Java runtime - if other WSS4J applications (like e.g. Oxalis) are also run, this switch does not solve the issue. Defaults to false.

  • phase4.profile: a specific AS4 profile ID that can be used to validate incoming messages. Only needed in specific circumstances. Not present by default (prior 0.11.0 this property was called server.profile).

  • phase4.incoming.duplicatedisposal.minutes: the number of minutes a message is kept for duplication check. After that time, the same message can be retrieved again. Valid values are integer numbers ≥ 0. The default value is 10 (prior 0.11.0 this property was called server.incoming.duplicatedisposal.minutes).

  • phase4.dump.path (since 0.11.0): the base path where dumps of incoming and outgoing files should be created, if the respective dumpers are activated. The default value is phase4-dumps relative to the current working directory.

  • phase4.endpoint.address: the public URL of this AS4 server to send responses to. This value is optional. (prior 0.11.0 this property was called server.address).

Profiles vs. PModes

To handle common parts of AS4 PModes this project uses so called "profiles". Currently two default profiles are available:

To use one of these profiles, the respective Maven artifacts must be added as dependencies to your project as in

    <dependency>
      <groupId>com.helger</groupId>
      <artifactId>phase4-profile-peppol</artifactId>
      <version>x.y.z</version>
    </dependency>

If you want to create your own profile, you need to provide an SPI implementation of the phase4-lib interface com.helger.phase4.profile.IAS4ProfileRegistrarSPI. See the above mentioned submodules as examples on how to do that.

Peppol handling

Peppol is an international eDelivery network. Read more on https://peppol.eu

Peppol Prerequisites

To perform testing with Peppol you MUST have a valid Peppol certificate. Testing with a self-signed certificate does not work. Only certificates that are based on the Peppol AP PKI will be accepted. You may read https://peppol.helger.com/public/locale-en_US/menuitem-docs-peppol-pki for more information on the Peppol PKI. To retrieve a Peppol certificate, you must be a member of OpenPEPPOL AISBL - see https://peppol.eu/get-involved/join-openpeppol/ for details.

Peppol AS4 specifics

OASIS AS4 is a profile of OASIS EBMS v3. CEF AS4 is a profile of OASIS AS4. Peppol AS4 is a profile of CEF AS4. Find the Peppol specification document at https://docs.peppol.eu/edelivery/as4/specification/

Peppol has a very limited use of AS4. Some highlights are:

  • It uses only one-way push
  • TLS certificates must have SSL labs test grade "A" - that means e.g. no TLS 1.0 or 1.1 support
  • Signing and encryption rules follow the CEF AS4 profile requirements (AES 128 CGM, SHA-256)
  • It allows only for one payload
  • You have to use MIME encoding for the payload - and are not allowed to add it into the SOAP body
  • The payload is always an SBD envelope (Standard Business Document; mostly wrongly addressed as SBDH - Standard Business Document Header) - same as for Peppol AS2
  • Compression must be supported but can be chosen on the senders discretion

Subproject phase4-peppol-client

This subproject is your entry point for sending messages into the Peppol eDelivery network.

The contained project contains a class called Phase4PeppolSender.Builder (accessible via factory method Phase4PeppolSender.builder()) - it contains all the parameters with some example values so that you can start easily. Alternatively the class Phase4PeppolSender.SBDHBuilder (accessible via factory method Phase4PeppolSender.sbdhBuilder()) offers a build class where you can add your pre-build StandardBusinessDocument, which implies that no implicit validation of the business document takes place. This class contains utility methods to explicitly validate the payload.

As a prerequisite, the file phase4.properties must be filled out correctly and your Peppol AP certificate must be provided (the default configured name is test-ap.p12).

See the folder https://github.com/phax/phase4/tree/master/phase4-peppol-client/src/test/java/com/helger/phase4/peppol for different examples on how to send messages via the Peppol AS4 client.

The client side validation of outgoing business documents is implemented using PHIVE (Philip Helger Integrative Validation Engine).

Subproject phase4-peppol-servlet

This subproject is your entry point for receiving messages from the Peppol eDelivery network.

It assumes you are running an Application server like Apache Tomcat or Eclipse Jetty to handle incoming connections.

Available from v0.9.7 onwards. Register the Servlet com.helger.phase4.peppol.servlet.Phase4PeppolServlet in your application. Then implement the SPI interface com.helger.phase4.peppol.servlet.IPhase4PeppolIncomingSBDHandlerSPI to handle incoming Peppol messages. See Introduction to the Service Providers Interface if you are not familiar with the Java concept of SPI.

Sample setup for WEB-INF/web.xml:

<servlet>
  <servlet-name>Phase4PeppolServlet</servlet-name>
  <servlet-class>com.helger.phase4.peppol.servlet.Phase4PeppolServlet</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>Phase4PeppolServlet</servlet-name>
  <url-pattern>/as4</url-pattern>
</servlet-mapping>

By default the "receiver checks" are enabled. They are checking if the incoming message is targeted for the correct Access Point. That is done by performing an SMP lookup on the receiver/document type/process ID and check if the resulting values match the preconfigured values. That of course requires that the preconfigured values need to be set, before a message can be received. That needs to be done via the static methods in class Phase4PeppolServletConfiguration. Alternatively you can disable the receiver checks using the setReceiverCheckEnabled method in said class.

Additionally before you can start, an IAS4CryptoFactory MUST be set. An implementation of this interface provides the keystore as well as the private key for doing signing and/or encryption services in phase4. Default implementations shipping with phase4 are AS4CryptoFactoryPropertiesFile and AS4CryptoFactoryInMemoryKeyStore. To change that configuration use the extended constructor of AS4XServletHandler that itself is instantiated in the Phase4PeppolServlet - therefore a custom Servlet class is required, where Phase4PeppolServlet should be used as the "copy-paste template" (and don't forget to reference the new servlet class from the WEB-INF/web.xml mentioned above).

Note: in v0.9.8 the receiving SPI method was heavily extended to be able to retrieve more information elements directly, without needing to dive deeper into the code.

Subproject phase4-peppol-server-webapp

This subproject shows how to a simple standalone Peppol AS4 server could look like. It is a demo implementation and does not do anything with the payload except storing it on disk. Use this as the basis for implementing your own solution - don't take it "as is". It takes incoming requests via HTTP POST at the URL /as4.

Upon startup it checks that a valid Peppol Access Point (AP) certificate is installed.

It stores all incoming requests on disk based on the incoming date time.

  • The full incoming message is stored with extension .as4in
  • The SOAP document is stored with extension .soap
  • The (decrypted) Peppol payload (SBD Document) is stored with extension .sbd
  • The returned receipt is stored with extension .response

To configure your certificate, modify the file phase4.properties. Usually there is no need to alter the truststore - it's the Peppol default truststore and considered to be constant.

Note: this application uses the property smp.url in configuration file phase4.properties to locate it's home SMP for cross checking if the incoming request is targeted for itself.

To start it from within your IDE you may run the test class com.helger.phase4.peppol.server.standalone.RunInJettyPHASE4PEPPOL - it will spawn on http://localhost:8080`. For IntelliJ users: make sure the folder phase4-peppol-server-webapp is the startup directory.

Usage with Maven

If you want to use phase4 with Maven I suggest the following way:

  1. add the BOM into your <dependencyManagement> section and
  2. add the main artefacts without version in the <dependency> block to have a consistent versioning:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
...
  <dependencyManagement>
    <dependencies>
...
      <!-- step 1 -->
      <dependency>
        <groupId>com.helger.phase4</groupId>
        <artifactId>phase4-parent-pom</artifactId>
        <version>x.y.z</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
...
    </dependencies>
  </dependencyManagement>
...
  <dependencies>
...
    <!-- step 2 -->
    <dependency>
      <groupId>com.helger.phase4</groupId>
      <artifactId>phase4-lib</artifactId>
    </dependency>
    <dependency>
      <groupId>com.helger.phase4</groupId>
      <artifactId>phase4-profile-peppol</artifactId>
    </dependency>
...
  </dependencies>
...
</project>

Note: prior to v0.9.17 the Maven groupId was com.helger.

Building from source

Apache Maven needed 3.6 or later and Java JDK 8 or later is required.

To build the whole package on the commandline use mvn clean install -U.

If you are importing this into your IDE and you get build errors, it maybe necessary to run mvn process-sources once in the phase4-lib subproject. Afterwards the folder target/generated-sources/xjc must be added to the source build path. When building only on the commandline, this is done automatically.

Known limitations

Per now the following known limitations exist:

  • phase4 is not a standalone project but a library that you need to manually integrate into your system
  • Multi-hop does not work

How to help

Any voluntary help on this project is welcome. If you want to write documentation or test the solution - I'm glad for every help. Just write me an email - see pom.xml for my email address

If you like the project, a star on GitHub is always appreciated.
