I am running a stand alone java class on a linux prompt, the java class has reference to 2 different classes in jar file
I am running this command

java -classpath /local/home/test/lib/commons-httpclient.jar:commons-logging.jar:. TestClass

I am running this command from the directory where I have TestClass. But it is not finding a class which is in commons-logging.jar

ANy help will really be appriciated

That would mean that commons-logging.jar is not in your current working directory. Perhaps it's in the same directory as commons-httpclient.jar? If so, then you should say that in your classpath.

try this
First check your class path
by

echo $CLASSPATH
if not set

CLASSPATH=".:/usr/java/jdk1.6.0_05/bin"

and complie like this which takes all jar in the folder or give path

javac -cp :\* test.java

then run
java -cp :\* test

There are two things wrong with this
1. The JDK bin directory does not contain any jar files or classes so does not need to be in the CLASSPATH. You probably do need it in your PATH environment variable.
2. There is no point in setting a CLASSPATH environment variable if you are going to use the -cp option, as this will cause the environment variable to be ignored.

In fact, setting a system classpath usually does more harm than good. I recommend, as well as following SB’s good advice, you delete that classpath as being completely unnecessary.
