Re: no ojdbc14 in java.library.path, Help I'm stuck trying to write this servlet!
I had this problem, and got it work by having the ojdbc14.jar in the '$CATALINA_HOME/common/lib' directory ONLY. If I kept a copy of ojdbc14.jar in my application's 'WEB-INF/lib' directory, the thing just did not work. Strange. I cannot explain it!

Re: no ojdbc14 in java.library.path, Help I'm stuck trying to write this servlet!
Thanks Apu,
It seems that having a jdbc connection in the web admin tool creates
more of a problem. I've removed all web connections and it seems to
work. Thanks again Apu, I really appreciate it!

no ojdbc14 in java.library.path, Help I'm stuck trying to write this servlet!
Hey All. I've been trying to write a servlet that uses a jdbc driver to connect to a remote Oracle server. I've manage to compile my own standalone app to connect to the DB. I included the ojdbc14.jar in my classpath and everything seemed to work fine. I can't seem to get the same code to work in a servlet with tomcat 5, and I'm pretty sure it's because tomcat does not know where ojdbc14.jar is. I've put it in server/lib and /bin and common/lib, but to no avail. Using the web tool, I've added the ojdbc14.jar file with multiple paths and i've still got nothing. Any help would be appreciates.
