Operating conditions: JDK + Jacob.jar + jacob.dll

1) put Jacob.dll in java_home\bin\ and java_home\jre\bin\ and C:\WINDOWS\system32\ catalogue
2) put the Jacob.jar into the project's Lib package, and load the jar package in the Java build path.
3) Run the project to compile the pass.

Note: Jacob.jar and Jacob.dll versions will match the JDK version, otherwise an exception may occur!
