naming exception

[prathap chnadran chandran <cp...@rediffmail.com>]

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
