Subject Error 500- Please help
Date Mon, 13 Aug 2001 03:55:30 GMT
Hi all.

I am a newbie to Tomcat and Soap. I need guidance.

I have set up Jakarta-tomcat3.2.1 on my machine and in combination with
Soap-2.2 and Xerces1.2.3 . (Soap, Xerces, both from IBM)
I am using the ancient Win95.

I made the setup changes in the server.xml , to support SOAP and also
set TOMCAT_HOME correctly.
I have also set the classpath correctly to contain xerces.jar and
soap.jar .

Now i run my apache-tomcat server to access the Apache-Soap index page.
All is fine till here.
But when i click on the LIST option , which should list existing web
services for me, then it throws an Exception. Also, if i click on
Deploy, then it does deploy my web service, and on clicking undeploy, it

shows me the id of my web service also, which i can undeploy.
But i get the foll. exception when i click on List.

Error: 500
Location: /soap/admin/list.jsp

Please help me on this.

Also, my client is not able to access the web service correctly.

It throws this exception:
SOAPException= SOAP-ENV:Protocol, Unsupported response content type
"text/html", must be: "text/xml". Response was:
<h1>Error: 500</h1>

I hope i get some solution to this.
I wonder if Win 95 is the cause of all this?

Thanks in advance.
Viva.
