Hello,
thnx for ur reply.
Now the jsp pages work fine. i deployed them as a .war file.
but now, the problem is with the compiler.
when i type javac -help, i get Jikes Compiler . (I use Debian LINUX in which
jikes comes bundled with kaffe VM.)
But earlier when i was not using Tomcat, i worked in Netbeans using J2SDK 1.4.
then the java files could be compiled. but now, after installing tomcat with
kaffe and jikes, both compilers (jikes as well as javac) do not work.
jikes filename.java givs errors.
Error:
Found 1 System error
***Semantic Error: You need to modify your classpath, sourcepath,
bootclasspath and/or extdirs setup.Jikes could not find package java.lang in:
.
javac filename.java also givs errors.
Error:
found 20 Semantic errors
similar to the 1 stated above. servlet.http, variable names, method names
nothing found!
how should i correct this? im unable to proceed now. kindly guide me.
thnx in advance
regards
aparna

check whether .java & .class files for the JSP are being created in the work
folder. Work folrder is located at <tomcat
installation>/work/Standalone/localhost/<application name>.
If class files are not being created here for the JSP then check ur JSP for
extra semi colons which sometime creates problems for compilation.

I am running tomcat4. when i start Tomcat using /etc/init.d/tomcat4 start using
JAVA_HOME=/usr/lib/kaffe, tomcat stops to run almost immediately but says the
pid file still exists.
Now if i export JAVA_HOME=/usr/j2sdk1.4.2_09, and start tomcat again, it runs
comfortably.
But when i run jsp pages, on the browser, i get the following error.
