Weblogic JMS系統錯誤

Question

我們遇到了一個JMS錯誤，沒有太多需要處理：

org.springframework.jms.UncategorizedJmsException：在JMS處理期間發生未分類的異常。 嵌套的異常是weblogic.jms.common.JMSException：[JMSClientExceptions：055039]發生系統錯誤。 錯誤是java.lang.NullPointerException; 嵌套的異常是com.mywebsite.SendMessageSync（ProducerServices.java:131）上的java.lang.NullPointerException

  at com.mywebsite.SendMessageSync(ProducerServices.java:115) at com.mywebsite.Producer.sendMessage(FormsCRRProducer.java:56) at com.mywebsite.Producer.useNewGetTemplateData(GenerateFormsManagerBean.java:522) at com.mywebsite.Producer.GenerateFormsManagerBean.doService(GenerateFormsManagerBean.java:114) at com.mywebsite.Producer.doServiceWrapper(AbstractManagerBean.java:175) at com.mywebsite.Producer.doServiceRequest(AbstractManagerBean.java:151) at com.mywebsite.processcontainer.AbstractServlet.doManagerBeanServiceAndPresentation(AbstractServlet.java:1911) at com.mywebsite.processunit.servlet.CportalParamServlet.doService(CportalParamServlet.java:107) at com.mywebsite.fw.processcontainer.AbstractServlet.service(AbstractServlet.java:983) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:227) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:283) at weblogic.servlet.internal.TailFilter.doFilter(TailFilter.java:26) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) at com.mywebsite.processunit.filter.UploadMultipartFilter.doFilter(UploadMultipartFilter.java:28) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3229) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2002) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:1908) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1362) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:209) at weblogic.work.ExecuteThread.run(ExecuteThread.java:181) 

我唯一的線索是此錯誤指示的代碼中的第127行：

原因由：weblogic.jms.common.JMSException：[JMSClientExceptions：055039]發生系統錯誤。 錯誤是java.lang.Nul lPointerException

  at weblogic.jms.client.JMSSession.handleException(JMSSession.java:2853) at weblogic.jms.client.JMSConsumer.receive(JMSConsumer.java:629) at weblogic.jms.client.JMSConsumer.receive(JMSConsumer.java:488) at weblogic.jms.client.WLConsumerImpl.receive(WLConsumerImpl.java:155) at org.springframework.jms.core.JmsTemplate.doReceive(JmsTemplate.java:734) at org.springframework.jms.core.JmsTemplate.doReceive(JmsTemplate.java:706) at org.springframework.jms.core.JmsTemplate$9.doInJms(JmsTemplate.java:681) at org.springframework.jms.core.JmsTemplate.execute(JmsTemplate.java:447) at org.springframework.jms.core.JmsTemplate.receiveSelected(JmsTemplate.java:679) at org.springframework.jms.core.JmsTemplate.receiveSelectedAndConvert(JmsTemplate.java:784) at com.mywebsite.jms.service.ProducerServices.SendMessageSync(ProducerServices.java:127) ... 25 more 

這是第127行：

try {
    Thread.yield();
    //line 127 below
    status=(StatusMessageBean)getJmsTemplate.receiveSelectedAndConvert(statusDestination, "JMSCorrelationID='"+ producerMsg.getProcessID() +"'");
    Thread.yield();
} catch (Exception e) {
    Thread.yield();
    loggingInterface.doErrorLogging(e.fillInStackTrace());          
}       

根據BEA文檔，我們應該就錯誤055039與BEA取得聯系，但是在將其帶給他們之前，我想先嘗試在這里問一下？

其他錯誤：

造成原因：java.lang.NullPointerException

有任何想法嗎？

Answer 1

好吧，您的第一步將是弄清楚哪個引用為空。 您可以在執行第127行本身之前轉儲第127行中使用的每個變量嗎？
