Thanx Randy but I've placed my jar file with the classes needed at $CATALINA_HOME/common/classes/jCO.jar . This is not enough ?

RE: Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error -HELP-ME-PLEASE
A few questions to remove the obvious: 1. Have you restarted Tomcat after copying the jco.jar file? 2. Does the jco.jar file really have a file /com//jco.class? 3. Does Tomcat have permissions to read this file (more of an issue on Unix, but possible on windows)? 4. Can you run jar -xvf jco.jar to extract the jar file? 5. Have you tried putting the jar fine in the WEB-INF/lib directory to see if it works there? 6. Is Tomcat printing any error message (to catalina.log or the console) during startup that might indicate its not loading this jar? That's all I can think of right now. Try these and see if anything pops up, if not post back and I'll try another round.

RE: Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error -HELP-ME-PLEASE
So it executed the Servlet Login2 as evidence in the stacktrace
root cause
java.lang.NoClassDefFoundError
at Login2.doGet(Login2.java:51)
at
javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
... and it got all the way to line 51. It looks like there are other
classes from this jar package that are being invoked. If they are being
invoked with no exception then the jar file is found. But the class at line
51 is not found. My line counting isn't working so you need to point to the
source code line 51. Also assuming your classes are like this:
com.sap.mw.jco.JCO.Repository and the jco.jar file is in your WEB-INF/lib
directory.

RE: Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error -HELP-ME-PLEASE
Thanx Carl,
I've placed jCO.jar at $CATALINA_HOME/common/lib/ it didn't work. I've
tried to extract it and placed the classes at
$CATALINA_HOME/common/classes/ and didn't work either. Also, I tried
$JAVA_HOME/jre/lib/ext/jCO.jar and all other possible paths but tomcat
seemed that could not find it. I worked with Apache Jserv before and the
same servlets worked fine but I want to use Tomcat now.
Any idea someone ?
So it executed the Servlet Login2 as evidence in the stacktrace
root cause
java.lang.NoClassDefFoundError
at Login2.doGet(Login2.java:51)
at
javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
... and it got all the way to line 51. It looks like there are other
classes from this jar package that are being invoked. If they are being
invoked with no exception then the jar file is found. But the class at
line
51 is not found. My line counting isn't working so you need to point
to the
source code line 51. Also assuming your classes are like this:
com.sap.mw.jco.JCO.Repository and the jco.jar file is in your WEB-INF/lib
directory.
