Hi,

I added ini4j-0.5.1.jar to the my project classpath in eclipse using Project Properties->Build Path -> Libraries ->Add external Jars. My project is under version control. I added the following code at appropriate place:

Ini ini = new Ini(new FileReader("C:\\file.ini"));

for (String key : ini.get("Symbol").keySet())
{
  System.out.println( key + " = " + ini.get("Symbol").fetch(key));
}

When I run the project now I get

java.lang.NoClassDefFoundError: org/ini4j/Ini

which I think is due to the wrong classpath, but eclipse is recognizing Ini class fine, its even suggesting the header files to import and the methods.Can anybody please tell me how to set the correct classpath also how to do that manually and which files should be changed?Is it because the project is in clearcase and some of the files which should get changed is not changed since they are not checked-out?

When I created a test project outside of clearcase, ini4j worked!
I am very confused , please help.
Thank you

You edited the Build Path, but you have to also update the runtime
classpath of your Launch Configuration. A Launch Configuration is what
Eclipse uses to run the specific programs from your projects; in most
cases the runtime classpath of the Launch Config is automatically kept
up to date with your build path, but you may have to manually add this
JAR to yours for some reason.
Open the Run Configurations... or Debug Configurations... dialog to edit
your Launch Configurations.
