Hi all,
 I am using Tomcat 5.0.16(for testing purpose only). When a page is having
an error like missing semicolon or a special character in code it is giving
the following error in browser.
org.apache.jasper.JasperException Source code of 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.

Interestingly it is printing lots of lines in console including the
classpath and the actual error(; expected).
I am using it on Win2k SP4 machine which have both JDK1.3.1 and 1.4.1
installed. I compiled Tomcat from source. I  remember that JDK 1.4.1 is used
for compiling Tomcat and in startup.bat I have set the JAVA_HOME and
CATALINA_HOME to JDK1.4.1.  On getting error message I copied tools.jar to
common\lib and error persists.
