Software that can be used for conversion of jar file type to sis format.
It appears that jar to sis conversion was quite often searched for in the past years by users that were (or still possible are) trying to convert Java app installers to Symbian app installer for Symbian devices (older Nokia phones).
Unfortunately, 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.
Unfortunately, there is no detailed software record in the database for this conversion.
