JNI: Can't generated header 1

[YerMom]

I'm using javah to generate header file on windows XP. I'm using a batch file to start javah. Here is the contents of the batch file:

javah -verbose -classpath . -jni com.mycompany.doctools.apireferencecompares.TestFrameScript >> BuildHeaderLog.txt  2>&1

The batch file is in the directory where the TestFrameScript.class file is located. The directory is:

D:\D_LocalWork\CCBS\Doc_Tools\EclipseDocTools\bin\com\mycompany\doctools\apireferencecompares

In the Java source file, the package name is:

package com.mycompany.doctools.apireferencecompares;

When I run javah, I get the error shown below.

It looks like javah is not looking in the correct directory, even though I've included a -classpath in my command line invocation.
I'm not sure what's wrong. Can anyone help?

Thanks.

Error: No classes were specified on the command line.  Try -help.

The listing of the directory shows that TestFrameScript.class is indeed in the directory:

I'd try:

- Doing it from command line to avoid batch errors.
- Execute it from :\D_LocalWork\CCBS\Doc_Tools\EclipseDocTools\bin

Dian,
Thanks -- that works. Do you have any idea why the bat file approach did not work?

 

[Diancecht]

Because when you execute from command line java expects to be executed from the root of the packages.

Cheers,
Dian
