wicket-orientdb
Everything you need to work with Apache Wicket and OrientDB. Library contains several functional part which can be used separatly or all together.
Looking for examples? Orienteer - Business Application Platform
Initial setup of application
You should inherit WebApplication class from OrientDbWebApplication to use OrientDB and its authentication with in your application.
public class WicketApplication extends OrientDbWebApplication
Specify connection properties
getOrientDbSettings().setDBUrl("local:localhost/"+DB_NAME);
getOrientDbSettings().setAdminUserName("admin");
getOrientDbSettings().setAdminUserPassword("admin");
Embedded OrientDB Server
If you need to run OrientDB in embedded mode please use EmbeddOrientDbApplicationListener
public class WicketApplication extends OrientDbWebApplication
{
@Override
public void init()
{
super.init();
getApplicationListeners().add(new EmbeddOrientDbApplicationListener(WicketApplication.class.getResource("db.config.xml"))
{
@Override
public void onAfterServerStartupAndActivation() throws Exception {
OServerAdmin serverAdmin = new OServerAdmin("localhost/"+DB_NAME).connect("root", "WicketOrientDB");
if(!serverAdmin.existsDatabase())
serverAdmin.createDatabase(DB_NAME, "graph", "local");
}
});
getOrientDbSettings().setDBUrl("local:localhost/"+DB_NAME);
getOrientDbSettings().setAdminUserName("admin");
getOrientDbSettings().setAdminUserPassword("admin");
}
}
PropertyModel
To gain access to Orient DB document from your application please use ODocumentPropertyModel instead of common PropertyModel. Important! Following issue have been created to introduce support of custom properties models into wicket: https://issues.apache.org/jira/browse/WICKET-5623 If you interested in using PropertyModel as usual in wicket, please, take a look to following pull request: https://github.com/apache/wicket/pull/74
Security
It's easy to integrate with OrientDB security stuff: You can either specify static required orientDB resources
@RequiredOrientResource(value=ORule.ResourceGeneric.CLASS, specific="ORole", permissions={OrientPermission.READ, OrientPermission.UPDATE})
public class MyPage extends WebPage {
...
@RequiredOrientResources({
@RequiredOrientResource(value = OSecurityHelper.SCHEMA, permissions=OrientPermission.READ),
@RequiredOrientResource(value = OSecurityHelper.CLASS, permissions=OrientPermission.READ),
})
public class MyPanel extends Panel {
...
or provide them dynamically: just implement ISecuredComponent
public class SaveSchemaCommand<T> extends SavePrototypeCommand<T> implements ISecuredComponent {
...
@Override
public RequiredOrientResource[] getRequiredResources() {
T object = objectModel.getObject();
OrientPermission permission = (object instanceof IPrototype<?>)?OrientPermission.CREATE:OrientPermission.UPDATE;
return OSecurityHelper.requireResource(OSecurityHelper.SCHEMA, null, permission);
}
OrientDB objects prototypes
Sometimes it's useful to work with object without actual creation of that object. Examples: OClass, OProperty, OIndex - all this objects require pre-creation in DB. Prototyping microframeworks allows creation of 'Prototype' of some objects, modify it and only after that 'realize' it in real environment.
Usage:
OClass oClass = OClassPrototyper.newPrototype();
oClass.setName("MyClass");
oClass.setSuperClass(superClass);
OClass realOClass = ((IPrototype<OClass>)oClass).realizePrototype();
