Question

我有一个试图调用服务的应用程序而另一个服务似乎是超时的。问题是我的应用程序没有收到任何超时异常，虽然我确实看到打印到控制台的错误：

[7/8/13 12:39:32:360 EDT] 00000005 TimeoutManage I   WTRN0006W: Transaction 0000013FBF252E43000000010000000CE81CB4935851D5C13DECD3DBB2D463F0DBECAEE60000013FBF252E43000000010000000CE81CB4935851D5C13DECD3DBB2D463F0DBECAEE600000001 has timed out after 120 seconds.

使用以下设置创建客户端：

bindProvider.getRequestContext().put(com.ibm.wsspi.webservices.Constants.RESPONSE_TIMEOUT_PROPERTY , connectionProperties.getProperty(MyService.TIME_OUT));
bindProvider.getRequestContext().put(com.ibm.wsspi.webservices.Constants.CONNECTION_TIMEOUT_PROPERTY , connectionProperties.getProperty(MyService.TIME_OUT));
bindProvider.getRequestContext().put(com.ibm.wsspi.webservices.Constants.READ_TIMEOUT_PROPERTY , connectionProperties.getProperty(MyService.TIME_OUT));

MyService.TIME_OUT的值为20000，我已经确认它已正确设置。

捕获的代码调用服务如下所示：

try
{
    response = ((MyServicePortType) myService).doWebServiceOperation(request);
}
catch (Throwable e) //I know, catch Throwable is not very good but right now I'd be happy to catch ANYthing here!
{

    log.error("Webservice reported error",e);
}

即使我已将catch块更改为任何，我仍然没有发现任何异常。 WebSphere检测到事务超时，但我不知道为什么应用程序没有检测到Web服务调用中的超时。是否有一些我遗漏的东西会导致抛出正确的超时异常，以便我可以捕获它并将消息发送到应用程序框架？

Answer 1

好吧，我觉得很傻。

对于WebSphere来说，这些属性（RESPONSE_TIMEOUT_PROPERTY，CONNECTION_TIMEOUT_PROPERTY等......）的值应设置为秒，而我正在使用毫秒。

将20000更改为20已解决此问题。

建议我应该假设秒而不是毫秒的页面就是这个：http://pic.dhe.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.express.doc/info/exp/ae/rwbs_httptransportprop.html

WebService超时，但客户端没有收到任何异常
