Conversion of jar files to sis file format

jar to sis conversion was in the past often searched by users that were attempting to convert Java app installers to Symbian app installer for Symbian devices (older Nokia phones). Alas, there is no way how to convert jar to sis and it is unlikely that you can find jar to sis converter. However, a lot of Symbian devices allowed installation from .jar files, so maybe check this option out.
