Thanks a lot. After fixing some typos this code works perfectly fine. I tried
to omit the ContentHandlerWrapper and it also works (commented out in the
code).
Would it be accepted if I provided a patch to JXTemplateGenerator so it parses
a new tag jx:outputxml to implement this functionality?
var str = "<p>here is some <b>bolded</b> text</p>";
var is = new Packages.org.xml.sax.InputSource( new java.io.StringReader( str ) );
var parser = null;
var consumer = new Packages.org.apache.cocoon.xml.SaxBuffer();
try {
parser = cocoon.getComponent(
Packages.org.apache.excalibur.xml.sax.SAXParser.ROLE );
/*
var contentHandlerWrapper =
new JavaAdapter( Packages.org.apache.cocoon.xml.ContentHandlerWrapper,
{
startDocument: function() {},
endDocument: function() {}
} );
contentHandlerWrapper.setContentHandler( consumer );
contentHandlerWrapper.setLexicalHandler( consumer );
*/
parser.parse( is, consumer );
} finally {
if ( parser != null ) cocoon.releaseComponent( parser );
}
cocoon.sendPage( "view/test.jx", { buffer: consumer } );

Works also.
Is there some kind of "object AOP"? I mean is there a way to provide every
bizData with this streamer without explicitly declaring? I have a lot of
application context variables apart from this new streamer I would like to
expose to every view.
