JSP execution problem in Jboss_2.4.3_Tomcat_4.0

[andcerve]

Hi,

I have no problem executing servlets from Jboss_2.4.3_Tomcat_4.0 (the tomcat-test.ear file works) but I have problems with JSP !!!

This is the error that occurs:

PLEASE HELP!!!

Thanks

The problem is that JBoss doesn't have in its classpath the reference to the java compiler.

To fix this, do this
Unix: export JBOSS_CLASSPATH=$JAVA_HOME/lib/tools.jar:$JBOSS_CLASSPATH

Windows: JBOSS_CLASSPATH=%JAVA_HOME%\lib\tools.jar;%JBOSS_CLASSPATH%

THANK YOU VERY MUCH FOR YOUR HELP!!!

Everything works now!

Bye

I have the services started fine - both JBOSS and the embedded TOMCAT service - but when I try to get the JSPs(irrespective of the file having the JSP scriptlets) on the browser I get an OutOfMemory error or a NoClassDefFoundError. I even added the following lines onto the JBOSS_CLASSPATH :
export JBOSS_CLASSPATH = $JAVA_HOME/lib/tools.jar:$JBOSS_CLASSPATH.
Can someone please enlighten me as to why I get these errors and what I need to do to overcome them.

Hi

I'm using Tomcat5 with JBOSS
It has an exception and tells me to out the tools.jar in the common/lib of tomcat, howeve the tomcat5 under jboss doesnt have any common/lib :/

I have updated my JBOSS_CLASSPATH to contain the tools.jar however I still get this error:

org.apache.jasper.JasperException: Unable to compile class for JSP

No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the
JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.

If using an alternate Java compiler, please check its installation and access pa
th.

And please do notice that when I'm running my site on a stand alone tomcat5 I receive no errors at all!

I found the problem, if anyone is interested.

It seems like for any exception the stacktrace would tell the user to see his tools.jar! (I had a real one there, but with all this gigantic stacktrace i couldnt locate it previously)

but THe problem was that I got such a big stack trace that was telling me that there might be a problem with tools.jar.

it seems like if there is any exception with compilation the stack trace would include an error message for users to see their tools.jar! :/
