Net-beans.

Step 3: check out the Jar that already created under the project folder (./dist)

PS. to change the entry man class. choose it and edit in MANIFEST.MF       
    Main-Class: package.MainClass

OR 

change the Build.xml  and add below tag.

<manifest file="MANIFEST.MF">

Step 3: Create Batch File in the same folder (new text file and rename it by Ex: luncher.bat) ..
          jar cf myjar.jar manifest.mf loggingForm.class
       
          jar : refer to the jar.exe . which copile the jar file.
         c :   refer that you want to create JAR file.
         f : you want to specify the file name,
         myjar.jar : the name of the crated jar.
