java - Cannot lookup JNDI resource on redeployment -

Problem:

My web app listens to JMS messages in queue and processes messages . I have written some test cases which are for running on CI, to confirm whether messages have been received and processed properly

Spring Config

  & lt ;! - JMS message listener - & gt; & Lt; Bean id = "Some message listener" category = "com.whatever.MyListener" /> & Lt ;! - Cached Connection Factory - & gt; & Lt; Bean id = "Cached Connectional" category = "org.springframework.jms.connection.CachingConnectionFactory" & gt; & Lt; Property Name = "targetConnectionFactory" ref = "ActiveMakuConnection Factory" & gt; & Lt; / Property & gt; & Lt; Property Name = "sessionCacheSize" value = "10" & gt; & Lt; / Property & gt; & Lt; Property Name = "ReconnectOpenExpression" value = "true" & gt; & Lt; / Property & gt; & Lt; / Bean & gt; & Lt ;! - Spring message listener - & gt; & Lt; JMS: Audience Container Container-Type = "Default" Connection-Factory = "Cached Connection Factory" Accept = "Client" & gt; & Lt; JMS: listeners destination = "DESTINATION" riff = "some message listener" method = "on message" id = "jmsSomeMessageListener" /> & Lt; / Jms: listener-container & gt;   
  MyListener sees a JNDI database resource to get code inside the class to get an SDL  connection . The resource next to the JMS message depends on obtaining a valid SQL connection. JNDDI resource constraints to  resources  definition  context.xml .  
  
          At CI for the first time when I re-deploy the war using the Maven targets  tomcat: undeploy  and  tomcat: deploy , my message listener now obtains a database connection Not able to. I get the following exception  
  exception   
  java.lang.RuntimeException: javax.naming.NameNotFoundException: name [comp / env / jdbc / Postgrace] is not bound in this context. [Comp] Unable to find   
 This code is  DataSource   
  JNDI lookup code   < / P> 
  reference ctx = new initial concerts (); Datasource DS = (Datasource) CTX. Lookup ("java: comp / env / jdbc / postgres");   
 I have tried to solve this problem:  
 I suspect that due to a leak or inappropriate undeployment in an old context the application is unchanged without . By using  onDestroy ()  to stop message listener (jmsSomeMessageListener) from a  ServletContextListener  by  method No effort has been made.  
  Prevent the message listener before making a tomcat call: undeploy  did not help either I was hoping that restarting the listener would force it to use a new reference  
 Question:  
 Why is the  context  after revision becoming stale? It is only on the listener and not on the other code that looks at the same  context  What can I do to fix the problem? (I'm opening to restart the server for every CI construct, temporarily crush the problem)   
 
 
 I solved a similar problem where my database pool was open but I was unable to use JNDI after my war review. I closed the issue with the connection and closed it with JDDI when the war was not lowered.  
  import javax.servlet.ServletContextEvent; Import javax.servlet.ServletContextListener; Public Class Meals implemented ServletContextListener {Private string DB = "EFU"; @ Override Public Reconnaissance Recession (PCT); PGPoolingDataSource connectionPool = (PGPoolingDataSource) New InitialContext (). Lookup (db); If (connectionpool = null) {connectionPool.close (); New initial contact () Unbind (db); }}}   
 You need to add a block to your web, which is entering your class as a listener:  
  & lt ; Listener & gt; & Lt; Audience category & gt; Com.foo.bar.MyClass & lt; / Listener Category & gt; & Lt; / Listener & gt;
