Calling REST web service Dynamically gives NoClassDefFoundError

Hi Experts,

I am attempting to call a REST Web Service in PI 7.3, Single JAVA Stack.

I used the blog http://scn.sap.com/community/pi-and-soa-middleware/blog/2012/08/11/calling-synchronous-restful-web-s...

and http://scn.sap.com/community/pi-and-soa-middleware/blog/2012/08/18/consuming-synchronous-restful-web... posted by Amit Dingorkar as the starting point.

I am using an ABAP program on our ECC system to create/send a couple needed fields to PI via HTTP Proxy.

Following the above blogs, I created my url dynamically and put the value into the proper fields in the mapping, based on the blog. I then tested it using SPROXY on the ECC box.

Here is the message content showing that the mapping worked, the url and the TServerLocation both have the correct URL that I am setting up dynamically.

I am getting a General error when monitoring messages and the message cancels with the following Log.

...

The first message also shows up in Communication Channel monitoring for the Proxy Comm Channel and the SOAP channel that we used.

Anyone have any suggestions?

Thank you for your help,
Mike

Once again, thanks for any thoughts/help on this issue.

Hi Mike,

As far as you are using PI 7.3 with a single Java stack you need to add to your classpath

wsdl4j-1.6.2.jar

actually you could add axis-wsdl4j-1.5.1.jar since it's the version used by axis to build the 1.4 version, but I recommend you to use the last version which doesn't depend on axis and it's perfectly compatible.

You can download wsdl4j-1.6.2.jar from here http://sourceforge.net/projects/wsdl4j/

best regards,

Tena.
