Subject howto write flowscript in java? any examples?
Date Thu, 16 Sep 2004 11:50:49 GMT
Hi,

I have big problems with flowscript in cocoon 2.1.5.1.  It throws errors 
on the javascript code.
Is it possible to rewrite the javascript in java as a workaround?  Is 
there an example that explains howto do this?

I already tried to solve the exception but I keep walking from one 
exception into the other.
Is there somebody who has any experience with flowscript in Bea Weblogic 
6.1 sp6 on solaris?
I have the flowscript working on a Bea Weblogic 6.1 on windows but the 
fu**ing solaris is giving problems.
For the last stacktrace see below.
