Connection pool examples
Hi everyone!
I would like to know if there are some practical examples about how to
implement the Data Base Connection Pool API. (Tomcat, Oracle)
Could you please give me some references?
Thanks in advance
Nancy.

One more question about this:
Is it possible to implement a pool connection using Jakarta commons in Tomcat
3.3 or do I have to upgrade to 4.x?
This is because I found a couple of examples but they are implemented in Tomcat
4.x.
If I have to upgrade, which version do you recomend me?
Thanks,
Nancy.

NullPointerException on Netscape 6.2
Posted by Luminous Heart <lu...@yahoo.com>.
I get this exception everytime I try to login into my
application, running on tc4.0.4, on Netscape 6.2.
However that the application works fine with all
versions of IE. I am sure it is a Netscape issue, but
has anyone experienced anything like that?
It seems that my username and password are not passed
through when I sign in using netscape. Does netscape
support tomcat sessions?

I posted a guide/example regarding this not so long ago.
