Cannot create message: incorrect content-type for SOAP version. Got text/xml; charset=UTF-8, but expected application/soap+xml

I am trying to use the large merchant services API provided by eBay to upload files onto eBay.

They have provided with a sample.jar file of the same. It seems to be working fine when we execute the .jar file on the command prompt, but when i am trying to integrate its source in my web app its giving me this error. Also i tried to create a web service client using Netbeans and tried to use it, but still it gave me the same error. I also changed the SOAP version from 1.1 to 1.2 but that too doesn't seem to work. The following is the complete stack trace.

Got it to work, seems like my JDK was corrupt with all external jar files that i added to get it to work. Upgraded to Java 7 and it seems to be working fine now.
