Hi, can anyone help me in generating jni header file within/or with a project created with eclipse with the following path:
D:\workspace\DLLImportExample\src\com\dll\JNICom.java

When I'm trying to create the header file using javah -jni JNIComm, it's giving the following error:
D:\workspace\DLLImportExample\src\com\dll>javah -jni JNIComm
error: cannot access JNIComm
bad class file: .\JNIComm.class
class file contains wrong class: com.dll.JNIComm
Please remove or make sure it appears in the correct subdirectory of the classpa

D:\workspace\DLLImportExample\src\com\dll>

When I remove the package com.dll and set the default package, the javah -jni command runns successfully. Can you help me overcome the issue of package when running javah -jni.
Thanks

Thanks for the link, it's very interesting!

Hi, an other question is why javah -jni <classname> doesn't work if a package is specified in the class such as "package com.xxx.yyy;" (in eclipse), but if the package is set to the default, it's running without error.
