Packaging Options
There are two packaging options -
Create Obfuscated Package
and
Create Package.
Create Package
When the Create Package action is run, it will
deploy the JAD file and JAR file into the deployment directory specified in
the
Preferences.
The deployed JAR file will contain the verified classes and
resources.
Create Obfuscated Package
When the Create Obfuscated Package action is run,
it will deploy the JAD file and JAR file into the deployment directory
specified in
the
Preferences.
The deployed JAR file will be obfuscated by the using the Proguard Java Tool
as specified in
the Preferences.
Obfuscated packages are useful
in providing a small level of security for your deployed MIDlets. More
importantly, obfuscation generally leads to smaller deployed JAR file sizes.
In order to produce obfuscated packages, the Proguard Java obfuscation tools
must be installed and the root of the Proguard installation must be configured
in the
Obfuscation Preferences.
Proguard is a free open-source
library that is available for download from
https://proguard.sourceforge.net/.
Errors and Warnings During Obfuscation
It is possible that there will be warnings or errors during the obfuscation
process. When this occurs, a prompt will be opened to allow packaging to
continue or be cancelled.
If the warning or error can be safely ignored, you may select
Continue
and MTJ will attempt to continue creating the obfuscated package.
Depending on the type and severity of the problems encountered the package
may not be able to be created.
