Oh, of course. It works now. Ooops. :-(

However, just a minor problem, I have often noticed. When first trying
to access my web-page (C2, any version since July) after initially
starting TomCat, I always get the following error:

Error: 500

What is particularly weird (to me at least), as when I click reload,
it works.


Also, in order to play around and experiment with the potential uses
of XSP, I have created a simple "guestbook" application. The idea
being, the XSP file records new entries in XML format, which is
rendered using standard XSL style-sheets. I can give you copies if you
want, but personally I think my code is horrible ;-). For instance,
currently I have to display the result one way (without quoting
special characters, as XSP seems to do that for me), and save it to
the file another way (with quoting special characters).

However, in the latest version of Cocoon2 it no longer works anyway.
It seems to crash at the following line:

String name=request.getParameter("name");

with the following error:

java.util.NoSuchElementException
        at java.util.StringTokenizer.nextToken(StringTokenizer.java, Compiled Code)
        at org.apache.cocoon.components.language.programming.java.Javac.parseError(Javac.java, Compiled Code)

        at org.apache.cocoon.components.language.programming.java.AbstractJavaCompiler.getErrors(AbstractJavaCompiler.java, Compiled Code)
[...]

I would be interested in any relevant feedback in the above issues.

Thanks.
