Hi,
I have tried posting this problem in both the IDE Forum and this forum since The past one week and i haven't got any response.But i'm trying it one more time and i hope somebody helps me out.
The problem is that i am using NetBeans 5.0 version and i'm trying to create a connection pool using Microsoft SQL Server 2000.
I have added the three jar files i.e msutil.jar , mssqlserver.jar and msbase.jar to the netbeans-5.0\enterprise2\jakarta-tomcat-5.5.9\common\lib
then using the netbeans interface, i have created a jdbc pool with the
DataSource classname as: com.microsoft.jdbc.sqlserver.SQLServerDriver
url is : "jdbc:microsoft:sqlserver//localhost:1433;DatabaseName=Test"

the context.xml is this :


Now when i run the application... it throws this error :



I really can't understand what has to be done and i really need someone to help me out of this. Is it just the driver?

Thanks,
Bitz

'Help!!!' isn't a useful topic.

Try taking the jars you listed out of the common/lib directory and putting them in the server/lib directory instead.

The 'common' directory makes the code available to all web applications, but your intent is to create a DB pool managed by the server. Therefore it needs to be available to the server.

So it still looks like a loading issue, but after going back to read the instructions it looks like your initial setup was correct, the jars should go in the common/lib directory. I'll have a closer look Make sure you don't have any of the jars in your JAVA/jre/lib/ext directory

Nope, check your database url. I think you need to add an extra colon before the '//'

I changed the name of the topic so you get more responses. To come up with a more descriptive subject, try to pick some words that described the problem.

Hi,
Thanks a lot Dave. That ":" exactly was the problem. I feel so silly, but thanks a lot again.

Moral of the story : "Every problem has a solution and most of the times its as simple as adding a colon!! " ;)

Thanks Jeanne for changing the name.I got the solution


Thanks,
Bitz.
