javax.naming.NameNotFoundException: Name java:comp is not bound in this Context

To resolve this exception, need to cross check context.xml, web.xml and jar files.

Creation of context.xml in your META-INF auto generates the xml file with the project name in TOMCAT/conf/ ( C:\Program Files\Apache Software Foundation\apache-tomcat-6.0.18\conf\Catalina\localhost ) cross check this file.

compare context.xml and web.xml with the reference files posted in my previous posting.

No need to create an entry in TOMCAT context.xml and server.xml files.

Finally you need to check your lib folders, both tomcat and project lib.

If you have the following jar's in your lib folder, then remove those

a) naming-common.jar
b) naming-factory.jar
c) naming-resources.jar

clean and rebuild your project and then deploy it, before starting tomcat delete xml file from C:\Program Files\Apache Software Foundation\apache-tomcat-6.0.18\conf\Catalina\localhost

Apache Tomcat 6.0 JNDI Datasource

Configuration of JNDI

1. Create context.xml file in META-INF folder.

2. Create an entry for resource-ref in web.xml.

3. Make sure that the following JAR's added in your TOMCAT/lib ( C:\Program Files\Apache Software Foundation\apache-tomcat-6.0.18\lib )

a. commons-collections-3.2.jar

b. commons-dbcp-1.2.2.jar

c. commons-pool-1.4.jar

Note: for mysql add mysql-connector-java-5.1.5-bin.jar in TOMCAT/lib and for as400 add jt400.jar etc...
