connecting to DB?

[freefallenigma]

Hello,

I can't seem to connect to a database on my mac, but I can on the Linux machine I'm working on. I get an "Unknown Source" issue. Here's the error my mac gets when I try to load the app:
HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

I'm using EasyEclipse for the app, and Apache Tomcat.
Is this an issue connecting to the DB? Any ideas on why this is happening? Thanks.

Without more information, my guess is that the password for the DB user is not getting submitted. This is based on the NullPointerException in the validatePassword method.

We're using SVN and I am updated to the newest revision. I don't recall exactly when it stopped working but a week ago I could connect fine, though now that we've added more to the application, DB connection is essential. Hm.

What kind of info would be more helpful?

We're using Spring-MVC
My Mac: MacBook Pro 10.5.4

Thanks!

To troubleshoot, I'd check over the code that is actually doing the database connection that fails. Run the code through a debugger and see if there is a value for a password in the application at the time of failure. I would definitely focus on the changes/additions made to the application to ensure no conflicts there as that is the most likely cause.
