I have created a stand-alone Java web service client using stub class files and it works fine when it is run from Eclipse.
When I moved the client and class files from stub to a unix box where it is supposed to run from, I am facing an issue (by the way JDK on unix OS is: java version "1.6.0_07")
When I compile my Java client it compiles with warnings such as: /signer/SignServ.class: major version 51 is newer than 50, the highest major version supported by this compiler.
Note: SignServ.class is stub class file
When I try to "execute" my client Class file I am getting the error message: java.lang.UnsupportedClassVersionError: com/signer/EService : Unsupported major.minor version 51.0
Note: EService is also stub class
I understand the JDK/JRE version on UNIX box is lower than Java version on which stub class were compiled and this mismatch is throwing the error.
Problem is that I cannot upgrade JDK/JRE on UNIX box since it is controlled environment and policy bound.
Is there a way to get around this issue whist using stand alone java client? If not java client, any other alternative where I don't need to use stub class files?
Little more info - The webservice I am trying to invoke provide digital signature of PDF file. We need to send it a PDF file and it returns same with digital signature plus status messages.
Cheers!
