解决办法：
try
{
serviceClient = new RPCServiceClient ();
Options options = serviceClient.getOptions();
// 指定调用WebService的URL
EndpointReference targetEPR = new EndpointReference(wsURL);
options.setTo(targetEPR);
options.setManageSession(true);
options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT,true);
//指定某调用方法的参数值
Object[] opAddEntryArgs = inParams;
Class[] classes = outParamClass;
// 指定要调用的getGreeting方法及WSDL文件的命名空间
QName opAddEntry = new QName(nameSpace, methodName);
Object[] result=serviceClient.invokeBlocking(opAddEntry, opAddEntryArgs, classes);
serviceClient.cleanupTransport();
}
catch (AxisFault e)
{
e.printStackTrace();
}
catch (Exception e)
{
e.printStackTrace();
}
上述代码中的
options.setManageSession(true);
options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT,true);
serviceClient.cleanupTransport();
可以解决多次调用webservice后的连接超时异常
