有沒有一種方法可以使用和調用從C編譯的庫（如PJSIP庫）中的方法調用？如何在java上使用C庫（例如PJSIP）？
我想使用和調用從我編譯的pjsip庫調用，但顯而易見的問題是，pjsip是一個C庫而不是一個Java庫，即一個jar文件。
可能嗎？也許JNI？
感謝
編輯：使用痛飲試圖做手頭的工作，但它的作用是創建一個空的類文件。
這裏是我用來執行痛飲命令：從痛飲命令

pjsua Java類輸出
swig -verbose -java -package com.josh.sip.util -o jni_wrapper.c pjsua.i
它創造了我：

我有相同的位置，裏面的pjsua.h文件作爲我的.i文件所以它更容易找到兩者同時執行痛飲命令和任何意見？
我基本上想要swig或任何其他工具來創建一個pjsua或pjsip java類，它具有我可以用來實際使用庫的所有實現或接口方法。
如疼痛，有這個SIP協議棧
JNI是明顯的選擇，或可能[JNA]（https://github.com/twall/jna）。 – millimoose 2013-05-13 16:17:48
仍然存在問題。它不會生成帶有C源代碼中所有函數的jni。我甚至試圖複製和從C源代碼到所有我的jNI東西與標題以及 – jonney 2013-05-21 10:58:35
