Java 我是否可以更改配置，使jasper报告不'；你没时间吗？

每隔一段时间，生产系统上的用户就会为报告选择一个较大的日期范围，这会在一段时间后超时

我不知道这是在哪里配置的，但这是我得到的错误：

这是我在web.xml中看到的全部内容：

  <url-pattern>/servlet/report</url-pattern>
 </servlet-mapping>
<session-config>
  <session-timeout>30</session-timeout>
 </session-config>

报表Servlet
web.servlet.ReportServlet
3.
报表Servlet
/servlet/报告
30

有人知道我可以在哪里配置此属性吗？

请在调用报告的地方发布代码。“不清楚问题出在哪里，只是你的堆栈跟踪。”安吉丽娜：你在说什么超时？您应该添加更详细的信息和code@AlexK我假设从服务器返回报告时超时。为什么假设超时？。。我看到jasper.wsclient.WSException问题是jasper.wsclient.WSException是什么？

58  public ResourceDescriptor get(String uri, List args) throws WSException{
59      ResourceDescriptor descriptor = new ResourceDescriptor();
60      descriptor.setWsType(ResourceDescriptor.TYPE_REPORTUNIT);
61      descriptor.setUriString(uri);
62      try {
63          return server.getWSClient().get(descriptor, null, args);
64      } catch (Exception e) {
65          throw new WSException("Exception called during list.", e.getCause());
66      }
67  }
.   
94  public ResourceDescriptor get(String uri) throws WSException{
95      return get(uri, null);
96  }
