User development, A new message was posted in the thread "Migrate from Jboss 4.2.3 to Jboss 5.1.0 ==&gt; lookup("java:comp/env") threw exception": http://community.jboss.org/message/523873#523873 Author : James Norton Profile : http://community.jboss.org/people/lledmouse Message: -------------------------------------------------------------- Hi,   We are trying to migrade from jboss4.2.3 to 5.1.0 but We have not been successful.   Our application is a WAR file created with an external tool called AllfusionGen.   In Jboss4.2.3 We are doing the following:   1) rename jboss-4.2.3.GA\server\default folder to unittest76 2) copy WAR file (unittest76.war) to jboss-4.2.3.GA\server\unittest76\deploy 3) copy D2D1.sar folder to jboss-4.2.3.GA\server\unittest76\deploy   Now We are doing the same with Jboss5.1.0. It seems to work fine (the war is deployed) but once we load the main jsp We get the following error:     12:31:59,524 INFO  [STDOUT] 02/03/10-12:31:59:524[http-127.0.0.1-8080-1]: ServletRequest.setLoader(): *lookup("java:comp/env") threw: "javax.naming.NameNotFoundException: env not bound"* 12:31:59,618 INFO  [STDOUT] 02/03/10-12:31:59:618[http-127.0.0.1-8080-1]: LoadModule.getInstance(): Load Module get instance of sirius.TSEC0004.LoadModule.class  Failed: java.lang.NullPointerException.
