This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
hi folks, i always run into the following line of code as far as database connection is concerned from servletcontext:
i never seem to find out where the java:comp/env is defined. can you please explain me whatjava:comp/env is and where it is set up so that we could use it? thanks. [ April 08, 2003: Message edited by: Himal Chuli ]
java:comp/env is simply the root context for JNDI mappings you declare in your application. If you define a JDBC connection mapped to JNDI name jdbc/myDB, then you can access it through the context java:comp/env/jdbc/myDB. You never need to worry about defining java:comp/env anywhere. Some application servers (like JRun) will not require you to enter java:comp/env when performing a lookup, so check the documentation of your specific J2EE server for more information on JNDI names.

thanks for your reply to my concerns which helped me understand relatively better than before. But where and how is the java:comp/env defined so that JNDI recognize it? could i find the place it is defined and change it to something i would like to? thanks.
