Subject Re: Memory Leak in Tomcat
Date Tue, 22 Feb 2011 22:59:33 GMT
Hey,

When going to tomcat site, you can download "32-bit/64-bit Windows Service
Installer<http://off.co.il/apache/tomcat/tomcat-6/v6.0.32/bin/apache-tomcat-6.0.32.exe>
"
That's what I have installed. When installing this, it creates the tomcat
service in windows + the regular folder under c:\program files\apache
software foundation\Tomcat 6.0.
The tomcat service (on windows) ran with local system, and the connection
URL (of the DB) is specified under "c:\program files\apache software
foundation\tomcat 6.0\conf\catalina\localhost\*.xml"
In this xml file, along with the connection URL to DB, there is also the
user name and password of the user that have access to the DB, in clear
text.
In order for me to remove the user and password, I have changed the user
that runs the tomcat service to a domain user with access and permissions to
DB, placed the jdts-1.2.5.jar in the tomcat 6.0\lib folder and the
ntlmauth.dll (which is essential for the windows authentication to work) in
c:\windows\system32.

Now the tomcat service is running and authenticates to the DB with a domain
user (and not SQL user), but I have this memory leak as a side affect which
I'm trying (with, hopefully, the help of you guys) to resolve.

Thanks
Hila
