Soluton for Exception:FND_SOA_SERVICE_EXECUTION_ERR:oracle.apps.fnd.soa.util.SOAException

使用测试脚本调用Oracle EBS的一Webservice，报下边的错误：

FND_SOA_SERVICE_EXECUTION_ERR:oracle.apps.fnd.soa.util.SOAException: ServiceExecutionError: Error while executing the service Exception returned from JCA Service Runtime. Exception returned from JCA Service Runtime. null

从后端收集SOA Log里能够看到详细的错误信息:

Caused by: org.collaxa.thirdparty.apache.wsif.WSIFException: file:/xxx/soa/PLSQL/4392/XXXXXWS.wsdl [ XXXXXWS_ptt::XXXXXWS(InputParameters,OutputParameters) ] - WSIF JCA Execute of operation 'XXXXXWS' failed due to: Could not create/access the TopLink Session.

; nested exception is:
