The `!Java Packager tool`! is a tool included in the JDK which allows to package Java applications from the command line. It is an alternative to using other packaging tools like `F33f`_`[Apache Ant`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Apache_Ant]`_`f.`:cite-ref-1[`F5bf`_`[1`#cite-note-1]`_`f]

Note that the Java Packager does not automatically produce a `F33f`_`[Jar file`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=JAR_(file_format)]`_`f. Many other formats are available, including native executable formats for the platform.

The Java Packager tool also manipulates `F33f`_`[modules`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Java_Platform_Module_System]`_`f (added in Java 9), allowing for example to package a module and all the modules it depends on.`:cite-ref-2[`F5bf`_`[2`#cite-note-2]`_`f]

>>Example

For example, the following command will create a `*outputJar.jar`* file with the content of the `*classesDir`* directory, and will set the `*myPackager.MainClass`* as the executable class of the jar file:

`B100`F9d9javapackager -createjar -appclass myPackager.MainClass -srcdir classesDir -outdir out -outfile outputJar -v`f`b
