Datasource connection issues while upgrading from Jboss 5/6 to Jboss-as-7/Jboss eap

Posted on

While upgrading your application from Jboss 5 or 6 to Jboss-as-7 or Jboss eap, you may face datasource connection issue as follows:

(DefaultQuartzScheduler_Worker-1) Exception occured within if block of getDatasourceName method : javax.naming.NameNotFoundException: java:comp/env/jdbc/ExampleDB
at javax.naming.InitialContext.lookup( [rt.jar:1.6.0_37]
at [quartz-1.6.3.jar:1.6.3]
at org.quartz.simpl.SimpleThreadPool$ [quartz-1.6.3.jar:1.6.3]

To fix the above issue, you need to change the datasource connection as follows:

  1. In web.xml there will be no changes.
  2. In jboss-web.xml, the jndi-name has to be changed from java:/jdbc/ExampleDB to java:/ExampleDB as shown below:



3. In the class where you define datasource name, the datasource name has to be changed to java:/ExampleDB instead of          java:/comp/env/jdbc/ExampleDB.

Remove struts mapping messages from console

Posted on Updated on

You might be wandering that you have configured struts correctly but you still see some debug messages on the console related to struts config while starting any application server. Dont worry, struts is configured correctly. It is some other configurations that is displaying this message.  Read below to solve your issue.

It is due to some excessive code written in log4j configuration of your project. When the server runs, the debug message shown is something like below:


Convert string ‘/’ to class ‘java.lang.String’
Using converter ConverterFacade[StringConverter[UseDefault=true]]
Converting ‘String’ value ‘/’ to type ‘String’
setSimpleProperty: Invoking method public void org.apache.struts.config.ActionConfig.setInput(java.lang.String) with value / (class java.lang.String)
setProperty(ActionConfig[cancellable=false,path=null,validate=true,input=/,scope=session, parameter, methodName)
Target bean = ActionConfig[cancellable=false,path=null,validate=true,input=/,scope=session
Target name = parameter
Convert string ‘methodName’ to class ‘java.lang.String’
Using converter ConverterFacade[StringConverter[UseDefault=true]]
