Where is JDI class in J2SDK1.4.2?

I encountered the following error while running the Trace example:

D:\JPDA\Trace\classes>java com.sun.tools.example.trace.Trace

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/jdi/connect/VMStartException

Can someone help me how to resolve the JDI class?

Thanks!

The JDI classes are in tools.jar, which is part of the SDK

but is not shipped with the JRE.

You need to add tools.jar to your classpath:

On U*ix platforms:

java -classpath "$JAVA_HOME/lib/tools.jar:." com.sun.tools.example.trace.Trace

On win32:

java -classpath "%JAVA_HOME%/lib/tools.jar;." com.sun.tools.example.trace.Trace

Thanks. It is working as suggested. I thought the classpath environmental variable with d:\j2sdk142\lib will do the trick.THanks again.
