Re: Deploying a web service: UnsatisfiedLinkError

Hi,
Are you deploying multiple Web services in separate EAR files? The problem
occurs because the QYJSPART service program in jt400.jar is loaded more
than once by each of the EAR's class loader.

To work around the problem, you can define a global shared libary in
Websphere to jt400.jar.
Follow these steps:
1) Copy jt400.jar into a directory on the iSeries.
2) Launch the admin console.
3) Expand Environment -> Shared Library.
4) Click New to define a new shared library. Specify a name for the shared
library. The classpath should reference the jt400.jar  in step 1.
5) Expand Servers -> Application servers and select your Websphere server.
6) Under Server Infrastructure, expand Java and Process Management and
select Class loader.
7) Click New to define a new Class loader. Ensure the Class loader mode is
PARENT_FIRST and press OK.
8) Click on the Class loader you just created. Under Additional properties,
click Libraries.
9) Click Add. Select the shared library you defined in setp 4 and press OK.
10) Save all changes and re-start the server.


The other option is to create all your Web services in the same EAR.
