When mBooster is configured to output a JAR file, mBooster will compress the optimized classfiles and resource files into a JAR file using one of the following compressors as configured by the JAR.METHOD property:
| Compressor | Comments |
|---|---|
| MBOOSTERZIP | (Recommended) Integrated mBoosterZip compressor typically delivers a higher compression ratio than all widely known compressors, including 7-zip. |
| STANDARD | The standard compression library as implemented by J2SE (based on ZLIB). Use this compressor if the wireless operator is known to recompress JAR files using standard compression library |
| 7ZIP | The well-known 7-zip compressor (www.7-zip.org) with the maximum compression level (parameters -mx=9 -mfb=255 -mpass=4). Note: Disabled in the Evaluation Version |
The default compressor used is MBOOSTERZIP
The JAR compression step can be configured through this set of properties.
