如何在Eclipse中生成JNI头文件

Question

I am using Eclipse to generate a JNI header file. I looked in program files\\java\\jre6\\bin and found a lot of .exe and .dll files, but I couldn't find the command javah which was in the documentation for using JNI to create bindings to C libraries.
Any help?

Answer 1

Use the following panel to define a new external tool for javah.exe.

Point "Location" to the javah.exe tool.

Set "Working Directory" to

${workspace_loc:/${project_name}/bin}

Set "Arguments" to:

-classpath ${project_classpath} -v -d ${workspace_loc:/${project_name}/src} ${java_type_name}

To run the tool, highlight the java source file in package explorer and run the tool.

Press F5 to refresh th project to see the newly generated file.

Answer 2

Just some info...

Unfortunately the solution above did not work out for me, but the solution in this thread did:

Using javah -jni with an Eclipse project structure

With the above mentioned arguments, I got:

Exception in thread "main" java.lang.IllegalArgumentException: Not a valid class name:path/to/project

I found out, that the problem was a space character in the path to my project. Wrapping the paths in quotes did help for the solution above.
