Classpath problems or class missing

[mneds]

I am not sure where to go and post this type of question. I have done hours of online reasearch as well as gone through 3 levels of tech support at my college to try and fix this issue. I just bought a computer with Windows Vista and need Java to create graphs in my economics class. I downloaded it from java.com and checked to make sure it was there. They say it installed fine. When I try to access my graphing tool I get this error "java.lang.NoCl assDefFoundErro r:intellipro/utils/IP2DPlot" Does anyone know what this is or how to fix it? If not how about another place to go and ask questions like this?

Thanks,
mneds

I am moving this question to the Java forum as they may be able to help.

The intellipro.util s.IP2DPlot class is not a Java core class. I guess you have
a jar installed somewhere that contains this class. Make sure the jar can be
reached by the classpath or store the jar in the JAVA_HOME/lib/ext directory
if the documentation says so. Otherwise make sure your classpath is correct.

kind regards,

Even I faced this problem while accessing a learning application from Thomson Learning. Looks like the application is not able to access the JAR containing the class or the Class file itself is missing.

I think you have the same issue as the OP: check your classpath value.

ps. I'm going to change the title of this thread; I don't think it's a Java 1.6.01 bug;
the symptoms indicate otherwise.
