HTTP ERROR: 500 Unable to compile class for JSP..

[maciek]

hello

I tried to use jmx-console (jboss 3.2.1 + jetty) and when I opened http://localhost I could only see

HTTP ERROR: 500 Unable to compile class for JSP An error occurred at line: -1 in the jsp file: null Generated servlet error: [javac] Compiling 1 source file
RequestURI=/jmx-console/

I checked that a simple ejb works. Can you give me any hint what can be wrong?

regards

Make sure there are no spaces in your install path. I ran into similar problem, when i moved the jboss home from 'program files' it corrected the problem

This might be as trivial as having jre in your %JAVA_HOME% variable as opposed to jdk.

jre does not have all the components needed for jboss to run. double check that you are pointing to JDK

[hadek314]

your post suggests that you are pointing to jre.
an ejb is deployed after it's compiled so it will work with a jre.
plus if you read carefuly the error message it basically says that JBoss tried to access javac and didn't find it (hence NULL) javac is not included with jre.
