You may want to consider trying to use a REST API Descriptor (RAD) component in IS rather than using Java EE code. Not sure if RAD supports signing requests but if it does (and that is absolutely required by the Oracle endpoint you’re trying to call) that would be the way to go.

I think you have a java compatibility issue with the underlying JAR file. Also how have you packaged the jar dependencies, where have you put them ?

You need to provide a lot more information, java version?
How are you calling this class?
Where have you put your dependent libraries and what are they etc ?

And I agree with reamon, this not the webMethods way. You could run this as a standalone java app or in an apache runtime.

With webMethods you could do the above with just a couple of lines of code like;
