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?

${workspace_loc:/${project_name}/bin}
Set "Arguments" to:
“参数”设置为:
