put directory in classpath

[Susilo Saja]

I have a directory that contains a lot of jar file. Is it possible to put the directory in the classpath, instead of putting the jar file one by one?

hi
no. there is no way to just put the directory in the classpath.
u can probably write a loop in the script (.bat on windows and shell script on unix/linux) to do that for u...
i usually write following loop to include every jar file in the classpath
for i in `ls $HOME/jars/*.jar`
do
CLASSPATH=$CLASSPATH:$i
done
export CLASSPATH
javac *.java
this is assuming unix/linux and bash shell on it. somebody can provide the script on windows as well...
same way u can include .zip files if there are...

Hi,
It can be done but typically "- insert anti - Microsoft comment here -".
This will work on Windows 2000 machines. I have not tested it on anything else but I would imagine it should work on XP too.
First you need to make sure that Command Extensions and Delayed Expansion are enabled in your command shell. To do this make sure that the
following entries in your system registry (use REGEDT32 to check) are present and enabled (set to value 0x1).
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\DelayedExpansion
and
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\EnableExtensions
(You can also use a switch when running CMD.EXE to do this "CMD /E:oN /V:oN").
Once this is done the following script will do the same as the linux/unix script.
FOR %%I IN (*.jar) DO (
SET CLASSPATH=!CLASSPATH!%%~fI;
)
Hope this helps.

Thanks for answering Susilo's question, Malcolm.
As part of my moderator duties, I have to request you to change your name according to JavaRanch's Naming Policy. In your case you have to add a lastname.
Thanks
