Hi
I have developed a search servlet and deployed it in tomcat
4.0.3 and connected to mysql database through jdbc by specifying
jndi.
I have coded JNDI lookup name as
"java:comp/env/jdbc/KgoogleDB"
I have added a context in server.xml file of tomcat for DBCP
connection pooling .I have tested this in windows and it is
running well in it.
But when i hosted this in linux i got error like this
INIT OF SEARCH SERVLET
Error in file reading Connection refused
File Not Found
javax.naming.NameNotFoundException: Name java:comp is not bound in
this Context
