Java connection options

There are at least three options for using Java to connect to the FreeSWITCH Event Socket.

esl.jar (freeswitch core)

• License: Same as FreeSWITCH
• Available: esl.jar can be built as part of FreeSWITCH code base
• Features:
  • Automatically generated by SWIG from core C ESL interfaces (so by definition, always up to date with core ESL).

  • An example is provided at bottom of this page Event Socket Library.

org.freeswitch.esl.client (freeswitch-contrib)

  • Runtime dependencies only on the excellent Netty (Apache License) and SLF4j (MIT License) libraries

fs_eslib (Versafon)
