JNI for linux

[Chao Liu]

Hello, A problem was happened when I use JNI in linux to call my c programme. I used jdk1.3 and the following is my little test programm: ------JavaCallC.java------------------- import java.lang.*; public class  JavaCallC {  public JavaCallC()  {   System.loadLibrary("javac");  }  public native int StrInIntOut(String str);  public native String IntInStrOut(int iIndex);  public static void main(String[] args)  {      int tempint;   String tempstr;   JavaCallC obj = new JavaCallC();      tempint=obj.StrInIntOut( "Hello");      tempstr=obj.IntInStrOut(34);   System.out.print(tempint);      System.out.print(tempstr);  } } -------------------end--------------------------- then javac JavaCallC.java, javah -jni JavaCallC ----------------JavaCallC.c----------------------- #include <jni.h>    /* I have also try "include JavaCallC.h",error is still JNIEXPORT jint JNICALL Java_JavaCallC_StrInIntOut(JNIEnv * jenv, jobject jobj, jstring jstr) {  const char * thestr;  thestr=(*jenv)->GetStringUTFChars(jenv,jstr,0);  return 1234; } JNIEXPORT jstring JNICALL Java_JavaCallC_IntInStrOut(JNIEnv * jenv, jobject jobj, jint icount) {  char cptext[]="Java callc test";  long getint=icount;  return (*jenv)->NewStringUTF(jenv,cptext); } ------end--------------- then gcc -shared -o libjavac.so JavaCallC.c then java JavaCallC error was happened. Exception in thread "main" java.lang.UnsatisfiedLinkError: no javac in java.library.path         at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1312)         at java.lang.Runtime.loadLibrary0(Runtime.java:749)         at java.lang.System.loadLibrary(System.java:820)         at JavaCallC.<init>(JavaCallC.java:6)         at JavaCallC.main(JavaCallC.java:17)
