Error while executing WS client

[guptah]

Hi,

I am new to web services and am trying to write a simple Hello webservice. The web service deploys fine but when I try to call it using client, I get the following error: -

I am using JBoss 4.0.1, Apache axis 1.1, JWSDP 1.5.

Here is jaxrpc-ri.xml :-

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE webServices>








Here is config-interface.xml:-
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration>







Here is generated WSDL:-

<?xml version="1.0" encoding="UTF-8" ?>

Any help is most appreciated.

Thanks,

Could you provide a sample deployment in JIRA that allows me to reproduce what you are seeing? Ideally the client would be a Servlet, so that I only have to click on a link.

Hi Thomas,

Thank you for the reply. I am not aware of JIRA and what it does. I can send you the sample code for both client and services, if thats what you require.

Thanks,
Himanshu

There is another thing I would like to mention. I was not using Apache-axis until I tried to run client. The first time I tried to run client, I got and excaption that some file from org.apache.... package is missing. So, I downloaded Apache-axis and copied its jar files in Classpath for client. After that I started getting this SOAP error.

I wanted to mention this because I am not sure whether I was doing this right.

Again, your help is appreciated.

Thanks,
Himanshu

OK. I got it working using a JSP as a client. But, I cannot access this webservice from a stanalone Java class. Any ideas?

Thanks.
