Well we are getting somewhere with the webtrix stuff. It seems that if you turn on debugging in the embedded version of tomcat that we are using then exceptions are thrown. If you leave it off, then all is well.
Frustrating to say the least. So now that I can run webtrix I am slowly but surely migrating the JTrix.org site on to it. I am currently in the process of getting it to run jsp pages. This is something of an issue with the class loader. It seems you can set the class loader for tomcat, but you cannot set it for Jasper(the JSP compiler) Hence it seems to be struggling to find certain required base classes.
I can't seem to find a way to circumvent this, which is good since it means that Jtrix platform makes it difficult to run untrusted code.
Still I have always said I enjoyed a challenge.
