Multimedia Protector offers a perfect protection for .JAR files. They are protected against decompilation as they are not visible in the file system - See Virtual Zone.

 

Step 1 - Download Java Starter application

Download the Java starter application (jarstart.exe) and place it together with your .JAR file in a new folder. The folder can contain any number of .JAR files.

Step 2 - Import files

Now import all files and make jarstart.exe the start file.

 

 

 

 

Step 3 - Define Start Options

 

Simple start option

 

If your java application always needs the same start parameters, then you can place it in the field: command line parameter for EXE file . Select button Options, TAB EXE Options.

 

There are  Multimedia Protector specific variables:

 

-jarrun - runs the Java Virtual machine depending on registry settings

%path% - this is the complete path of the application

%envpath% - this is the environment path variable of the operating system (in a batch file the name would be %path% but it has to be replaced with this special variable %envpath%)

 

 

 

 

Complex start options

If the java applications needs complex start options (e.g. using a .bat file) then leave the field: command line parameter for EXE file empty.

 

Invoke the Multimedia Player using command line parameters.

 

Example

 

The name of the  Multimedia Player  is javatest.exe. The following command starts javatest.exe with a command line parameter. The Java Runtime would be loaded from the folder .\PortableApps\CommonFiles\Java\bin\javaw.exe, a path is set with the special variable %envpath% (means operating system variable %path%) and the jar file myapp.jar is loaded.

 

 

application\javatest.exe .\PortableApps\CommonFiles\Java\bin\javaw.exe -Duser.home=".." -Djava.library.path="%ENVPATH%;application\;" -jar "myapp.jar"
