jsp error : No Java compiler available

[cgo]

Hi,

I am trying to deploy an application in jboss 4.2.1, I have the error below when I try to access a JSP file. The application runs fine when I use Tomcat 6.0.14 as a standalone server but not in jboss. I have set JAVA_HOME to a JDK 1.5 folder but my understanding is that it should work even with a JRE as there is an included compiler. Anyone had this issue before ?

thanks,

Cyril

I still have this issue, however when setting jboss logs to debug I see the 2 NoClassDefFoundError exceptions below. I checked and the first class is in jasper-jdt.jar in the web deployer while the second one I could not find it, so I dropped ant.jar which contains it in the web deployer, but still it doesn't find any of the class. Any idea of what is wrong here ? Is jboss missing some files ?
