Ok,
I continue my investigation.
So I think I don't need to override my service but only override my
service configuration.
So my service is :
PageRenderInitializer
and my service configuration is :
contributePageRenderInitializer( ...
As write in the documentation :
"The extensibility comes from the fact multiple modules may all
contribute to the same service configuration:"
So I override the the contributePageRenderInitializer with :
public void
contributePageRenderInitializer(OrderedConfiguration<PageRenderCommand>
configuration,
final SymbolSource symbolSource,
final AssetSource assetSource) {
configuration.add("PageRenderSupport", new PageRenderCommand() {
public void cleanup(Environment environment) {
environment.pop(PageRenderSupport.class);
Document document = environment.peek(Document.class);
DocumentScriptBuilder builder =
environment.pop(DocumentScriptBuilder.class);
builder.updateDocument(document);
}
public void setup(Environment environment) {
DocumentScriptBuilder builder = new
MyOwnDocumentScriptBuilderImpl();
environment.push(DocumentScriptBuilder.class, builder);
environment.push(PageRenderSupport.class, new
PageRenderSupportImpl(builder,
symbolSource, assetSource));
}
}, "before:*");
}
It's an ordered list so I add the "before:*" statement to reflect the
order that I can see in the original method.
But this approach don't work : first my method is call twice !!!!
And the method throw and exception like :
11:21:18,796 - [SocketListener0-1] ERROR - PageRenderInitializer:

Caused by: java.lang.RuntimeException: Error invoking service

Thank for any input ;)
