A couple of weeks ago I posted a question about adding a "selectBoolean" tag to JXForms and the response I got was basically "you do it". So, I went and did a few modifications to relevant source files under blocks/jxforms and I'm not sure how to compile just that. So I rebuilt all Cocoon and then I substituted the newly generated "cocoon-jxforms-block.jar" file in place of the old one (yes, I did a backup copy :-) Now, after I restart Tomcat, Cocoon doesn't work. Any request into the /cocoon webapp just returns empty. Not even the Cocoon home page works. The modifications I made were very minor, just a shy first attempt. No syntax errors, everything compiled right, and it was in a couple of files belonging to blocks/jxforms like I said above. So... evidently I don't have a clue about what I'm doing and whoever wrote JXForms could add this feature in 20 minutes but nobody has identified himself as such. The logs in Tomcat show these exceptions: java.lang.NoClassDefFoundError: org/apache/cocoon/generation/ServiceableGenerator but I'm not sure whether they are related. Is there anything I'm missing? Is there an easy way to compile just the modified block?
