JarCastingLibrary to make it easy to register new URL schemes for java.net.URL. Consider:
@Test
public void testRegisterHandler() throws Exception
{
UrlSchemeRegistry.register("dinner", DinnerHandler.class);
assertThat(read(new URL("dinner://steak"))).isEqualTo("steak");
}
which uses the URL handler:
public class DinnerHandler extends URLStreamHandler
{
@Override
protected URLConnection openConnection(URL u) throws IOException
{
final String breakfast = u.getHost();
return new URLConnection(u)
{
@Override
public void connect() throws IOException { }
@Override
public InputStream getInputStream() throws IOException
{
return new ByteArrayInputStream(breakfast.getBytes());
}
};
}
}
The library uses the java.protocol.handler.pkgs system property and runtime generated classes following the correct package and class name conventions to accomplish this. It does not use URL.setURLStreamHandlerFactory(...); for this (so code using this library should run fine inside Tomcat which does use that method).
Releases are distributed via Maven Central. There are two variants, one with a dependency on cglib-2.2.2
<dependency>
<groupId>org.skife.url</groupId>
<artifactId>url-scheme-registry</artifactId>
<version>0.0.1</version>
</dependency>
or and one which renamespaces and bundles cglib-2.2.2.
<dependency>
<groupId>org.skife.url</groupId>
<artifactId>url-scheme-registry</artifactId>
<classifier>nodep</classifier>
<version>0.0.1</version>
</dependency>
Good luck!
