jni - How to use a C library such as PJSIP on java? -


is there way use , invoke method calls library compiled in c such pjsip library?

i want use , invoke calls pjsip lib have compiled obvious issue pjsip c library not java library ie jar file.

possible? maybe jni?

thanks

edit: tried using swig task @ hand create empty class file.

here command use execute swig:

swig  -verbose -java -package com.josh.sip.util -o jni_wrapper.c pjsua.i

output swig command

    language subdirectory: java search paths:    .\    .\swig_lib\java\    c:\users\jonney\downloads\swigwin-2.0.9\lib\java\    .\swig_lib\    c:\users\jonney\downloads\swigwin-2.0.9\lib\ preprocessing... starting language-specific parse... processing types... c++ analysis... generating wrappers...

pjsua java class creates me:

    /* ----------------------------------------------------------------------------  * file automatically generated swig (http://www.swig.org).  * version 2.0.9  *  * not make changes file unless know doing--modify  * swig interface file instead.  * ----------------------------------------------------------------------------- */  package com.josh.sip.util;  public class pjsua { }

the pjsua jni file creates me

/* ----------------------------------------------------------------------------  * file automatically generated swig (http://www.swig.org).  * version 2.0.9  *  * not make changes file unless know doing--modify  * swig interface file instead.  * ----------------------------------------------------------------------------- */  package com.josh.sip.util;  public class pjsuajni { }

the jni_wrapper.c generates me below:

i have pjsua.h file inside same location .i file easier find both whilst executing swig command , advice?

i want swig or other tool create pjsua or pjsip java class implementations or interface methods can use use library.

such pain there no java version of sip stack

try jna jnaerator: https://code.google.com/p/jnaerator. i've used in own projects.
