Unable to compile JSP under embedded Tomcat

Hi,

I have a struts-based application running within embedded Tomcat - it works fine on my machine. However, when I move it to another machine and try to run it I get an error from ONE of the jsps - others run fine. The error I get is:
-----
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 path.

As I said, other JSPs in the application work fine, so I ssumed it might be a typo but I've checked and checked and cannot find one (all "" ; etc are okay as far as I can tell). I've included the tools.jar in my classpath (set in a bat file when the app runs).

Does anyone have any ideas?

Please try tomcat suggestion

You may include this jar file to classpath or set it in bat file but it does not match exactly with what Tomcat suggest.

There is no /common directory in Embedded Tomcat - I've copied it to /lib but this doesn't work.

Do you have this directory "C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib" ?
Or TOMCAT_HOME\common\lib

what version of tomcat are you using?
Its Embedded Tomcat version 5.0.25

The directory structure is:

Tomcat/
         classes
         conf
         lib
         src
         webapps
         work
I'm 5.0.25 too but I have ?
try to reinstall with full package.
Are you using standard version 5.0.25 or 5.0.25-embed?

I've reinstalled this embedded version and still don't get a /common folder.
I think that's a different version - not the embedded one.

I've managed to solve this problem anyway - I just re-ordered some of the tags on my JSP page - moved the meta tags above the struts logic tags and it all works okay.

Thanks anyway for your help.

Steve.
That's ok :)
