解决办法：

[java] view plain copy
  1. try??
  2. {??
  3. ????serviceClient?=?new?RPCServiceClient?();??
  4. ????Options?options?=?serviceClient.getOptions();??
  5. ????//??指定调用WebService的URL??
  6. ????EndpointReference?targetEPR?=?new?EndpointReference(wsURL);??
  7. ????options.setTo(targetEPR);??
  8. ????options.setManageSession(true);???
  9. ????options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT,true);???
  10. ????//指定某调用方法的参数值??
  11. ?????Object[]?opAddEntryArgs?=?inParams;??
  12. ?????Class[]?classes?=?outParamClass;??
  13. ????//??指定要调用的getGreeting方法及WSDL文件的命名空间??
  14. ??????QName?opAddEntry?=?new?QName(nameSpace,?methodName);??
  15. ?????Object[]?result=serviceClient.invokeBlocking(opAddEntry,?opAddEntryArgs,?classes);??
  16. ?????serviceClient.cleanupTransport();??
  17. ?}??
  18. ?catch?(AxisFault?e)??
  19. ?{??
  20. ????e.printStackTrace();??
  21. ?}??
  22. ?catch?(Exception?e)???
  23. ?{??
  24. ????e.printStackTrace();??
  25. ?}??


上述代码中的

[java] view plain copy
  1. options.setManageSession(true);???
  2. options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT,true);???
  3. serviceClient.cleanupTransport();??

可以解决多次调用webservice后的连接超时异常
该错误参照apache官网：

https://issues.apache.org/jira/browse/AXIS2-4797
