again Xindice and Tomcat
we are developing a web application XXX that should access to Xindice. Both XXX and Xindice (1.1 from CVS!) are running under Tomcat 4.1.12.
At the XXX application start up XXX tries to get a collection by invoking org.xmldb.api.DatabaseManager.getCollection(xmldb:xindice://server-IP:8080/db/our-db)
but a "problem" arise:

Re: again Xindice and Tomcat
Posted by Christian Gross <ma...@devspace.com>.
Have you ever tried to debug Tomcat with the Xindice stuff included?
Because from where I am looking it appears the the GetCollection class is
bombing (duh!). When initially I was working with Xindice I could not
figure out some errors until I used the debugger to look at them. For
example in one instance it was because the string retrieved by XMLRpc was
not correct and needed a tweak in the XMLRPC client....
I would use a JPDA debugger like the one that comes with SlickEdit. Works
like a charm.
