Hi all,
1. Where can I find out more details about dl
interface(load, use, unload shared library)? any manual or URL?
2. We know that JNI need to create .so shared
library file. Could we load, use this file? E.g. I created fromjava.java and
fromjavaImp.c.
I compiled fromjava by
javac fromjava.java
javah -jni fromjava
I compiled fromjavaImp.c by
gcc -shared
-I/usr/java/jdk1.3/include -I/usr/java/jdk1.3/include/linux fromjavaImp.c -o
libfromm.so
to get libfromm.so file. When I run java
fromjava , it will pass a java string str to native program
fromjavaImp.c (libfromm.so).
Could we use other C
program e.g. breaklib.c to load this libfromm.so, and get the string (passed
from java)?
3. It looks comlicated, is it? Actually what I
trying to do is JVM (JNI_CreateJavaVM) invokes JNI. JNI module will pass
java string to C native program. JVM module will get this string from the native
program (libfromm.so) and process it.
p/s: I tried so hard to access java string
from C by using C invokes Java (JVM), but I failed. So, I create jvm
inside C , and access java string by loading libfromm.so(JNI). Is it possible?
If anyone know how to access java string from C by using C invokes Java (JVM),
please let me know. Any example?
Thank you very much
