Setting Library On Jars In Classpath

[Vikas Aggarwal]

Hi,
I have a directory named lib in C drive like c:\lib. It has near about 100 jar files. Now I want them to get into classpath without specifying each and every jar name.
I tried like
SET CLASSPATH=C:\lib;%CLASSPATH%
but none of the jars get into the classpath. My programs give errors (ClassNotFoundException) for the classes which are present in the jars though I am importing them correctly. For example in c:\lib there is jar in which the files are under package com.sgn.MyContext, then I am importing it like import com.sgn.MyContext.*;
Trying to access any of the classes under this package gives ClassNotFoundException.
Please help. It is very urgent.
Thanks.

I would suggest creating a batch file that contains the command necessary for executing your application. This way you only have to type the names of the 100 jars once and can easily add and remove jars as you wish.
Then at the command line you just have to type: YourCommand.bat and your application will run.

Thanks for your suggestion. I have also tried that and the files compile successfully but at run time it doesn't help. I need to have all the jars in my classpath at run time. In other words I will have to specify them in autoexec.bat(win98) or in environment variable' classpath(winNT).
I tried to do c:\lib\*.jar in the autoexec.bat. It doesn't help. Any suggestions?

Do you have a copy of Apache Ant? If not, do download it; for its own sake as much as for what follows.
In jakarta-ant-*/bin/, observe how the ant.bat file uses a for loop calling lcp.bat to build a CLASSPATH containing all the jars in lib/. Recycle the idea with abandon.
