- did you do the Servlet mapping in web.xml?
- Editing CLASSPATH in Tomcat's script only makes things worse. Classloader
is smart enough to load all the necessay jars.
- my CLASSPATH only contains tools.jar and .;
- my PATH only contains $JAVA_HOME and %ANT_HOME/bin

Subject: Very strange behavior, please, HELP (GenericServlet problem, error
500)
Hi All,
I've got Tomcat 4.1.18 + Apache 1.39 (Solaris, Sparc); Tomcat itself
works OK (shows examples, docs and all stuff).
When I try to execute one servlet, it gives me error 500 (see error text
below).
I've put into CLASSPATH everything *.jar (then restarted Tomcat and
Apache), copied all the jars into <tomcat>/common/lib but the errors
still apprears.
I've also edited catalina.sh and hardcoded CLASSPATH there just to be
sure Tomcat wouldn't miss it for some mistique reason. Still no progress.
Here is CLASSPATH:
/usr/java1.2/jre/lib/exactvm.jar:/usr/java1.2/jre/lib/rt.jar:/usr/java1.2/li
b/dt.jar:/usr/java1.2/jre/lib/ext/javax/servlet:/usr/java1.2/jre/lib/ext:/us

r:/metrics/tomcat/common/lib/chart.jar:/usr/java:.:/metrics/tomcat/common/li
b/servlet.jar:/metrics/tomcat/common/lib:/metrics/tomcat/common/lib/chartSer
ver.jar
I've seen the similar errors topics where the advice "include tools.jar
into CLASSPATH" seems to be working.
I'm kind of new in Servlets, so I don't really know what to dig. Any
advice will be appreciated.
Thanks,
Pavel.
