Patrick, I ran into this problem as well. I believe it has to do with the wsrp4j-producer.xml file that is copied to the $CATALINA_HOME\conf\Catalina\localhost directory (see the question I posted to this list earlier in the month).
In my testing, this file caused problems on Tomcat 5.0.x, but not on Tomct 5.5.x. When I fixed the path value in this file, I was able to get things running on both versions of Tomcat. Brian -----Original Message----- From: Patrick [mailto:[EMAIL PROTECTED] Sent: Thursday, March 23, 2006 1:52 AM To: [email protected] Subject: Re: Unable to run WSRP4J portlet examples thanks to both for the help Julie I confirm I have the exact same libs you mentioned. Brian, that was very much it, Pluto is indeed much happier now that the web.xml has been populated. Apart from a slight problem, I had to replace <distributable>false</distributable> with <distributable></distributable> otherwise it gives you this: --------- 23-mar-2006 9.21.41 org.apache.commons.digester.Digester error GRAVE: Parse Error at line 29 column 38: The content of element type "distributable" must match "EMPTY". org.xml.sax.SAXParseException: The content of element type "distributable" must match "EMPTY". --------- I could go a bit further but not much :-( So eventually it went passed the initial problem ... but I keep having a problem running the test portlet though. Now it complains that it cannot find the ContextPath for the Test Portlet web app as weird as it sounds. I controlled with Tomcat manager, had a test call to the context /wsrp4j-testportlet, all fine. Again to understand a bit further why this all happens I just added some traces to Pluto where I dump the WeAppDefinition object before the call to getContextPath(). As you can see, at the end of the dump it even displays the actual web app context it is looking for: contextPath='/wsrp4j-testportlet' Any idea ? is there another config issue you may know about ? N.B.: I tried to run the Producer on both Tomcat 4.1 and 5.5 but got the same error each time.
