help please with Error: 500
I've been struggling with this for a while now. I essentially have the Hello world example where a string is sent in and a string is returned. I am running
tomcat3.2.1, xerces1.4.1, jdk1.4 here's a listing of my classpath:
Using CLASSPATH: C:\Progra~1\Apache\tomcat3.2.1\lib\ant.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\activation.jar;C:\Progra~1\Apache\tomcat3.2.1
\lib\mail.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\soap.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\xerces.jar;C:\Progra~1\Apache\tomcat3.2.1
\classes;C:Progra~1\Apache\tomcat3.2.1\lib\activation.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\ant.jar;C:\Progra~1\Apache\tomcat3.2.1\lib
\jasper.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\jaxp.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\mail.jar;C:\Progra~1\Apache\tomcat3.2.1\lib
\parser.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\servlet.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\soap.jar;C:\Progra~1\Apache\tomcat3.2.1\lib
\webserver.jar;C:\Progra~1\Apache\tomcat3.2.1\lib\xerces.jar
I am able deploy the web service and verify it with a listing request but when I actually attempt to make a call I get a 500 error. Does anyone have an
idea what is wrong?? I've added my deployment descriptor and client connect info. Also the client and server side stack trace if that helps.
thanks,
