Hi Shreedhar and rest of you,
I am still getting the same error in the terminal windows. Is there some
problem with my JDK ? I don't think so though. I still believe that I am not
able to add the libraries properly. Here is what I did -
1. Copied the jar fliles jxta.jar and shoal-gms.jar to my C: drive root
folder.
2. Compiled the java code with the file name SimpleGMSSample
3. Tried to run it using - >
java -classpath .;C:\shoal-gms.jar;C:\jxta.jar SimpleShoalGMSSample
Still getting the same errors. I wonder what is wrong :((
PS: I know I'm quite a newbie at Java. Please bear with me :(
Thanks
Kushal
