need to fix" noClssDefFoundError"

[Eung maeng]

Hi,
anyone can let me know how do I fix this error when I run this.batch file to run my own class.



e.g batch file
set VertexSampleProg=IBCJF510TaxAreaLookup

:check_VertexSampleProg:
if not "%VertexSampleProg%"=="" goto RUN_PROG
set VertexSampleProg=IBCJF510TaxAreaLookup

:RUN_PROG:

echo Running Sample: %VertexSampleProg%

java -DVertexRoot=.\config -Xmx512m -Xms128m -cp .\LIB %VertexSampleProg%


pause

goto one:

my j2sdk1.4.2_12 is in c:\j2sdk1.4.2_12\bin folder.

Please fix it for me.

thanks,

NoClassDefFoundError always means that your classpath is not correct.

You do have a "-cp" switch on the command line. What is in that directory? Does it contain a file IBCJF510TaxAreaLookup.class? If not, then where is your class file?

Please fix it for me.

We don't really do that here. we can help you learn to fix your own programs, however.

I am not a shell script person, so i'll ask this:

What happens when you just try and run the java program directly, i.e. without the shell script?

I would use an absolute pathname in the CLASSPATH instead of a relative one. Also be sure to include . in the CLASSPATH.

A.class is \api\bin (run batch pgm here)
*.jar which imported in source is in \lib

directory,
\\vertex\api\bin
\\vertex\lib

Read the JDK documentation, look at this: How to set the classpath, How Classes are Found.
