How to generate JNI header file in Eclipse
提问by holy
I am using Eclipse to generate a JNI header file. I looked in program files\java\jre6\binand found a lot of .exeand .dllfiles, but I couldn't find the command javahwhich was in the documentation for using JNI to create bindings to C libraries.
Any help?

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.
我发现问题出在我的项目路径中的空格字符。将路径用引号括起来确实有助于上述解决方案。
