java - JNI UnsatisfiedLinkError undefined symbol -


i trying load .so file (libinfexprparser.so) using jni. not have source code shared object. getting following error:

exception in thread "main" java.lang.unsatisfiedlinkerror:/home/tomcat/sahithi/exprparser/libinfexprparser.so: /home/tomcat/sahithi/exprparser/libinfexprparser.so: undefined symbol: _zn8iustringc1epkcm @ java.lang.classloader$nativelibrary.load(native method) @ java.lang.classloader.loadlibrary0(unknown source) @ java.lang.classloader.loadlibrary(unknown source) @ java.lang.runtime.loadlibrary0(unknown source)
@ java.lang.system.loadlibrary(unknown source) @ expressionparser.main.(main.java:20)

java code: 

native void parseexpr();  static {     system.loadlibrary("infexprparser");     system.out.println("loaded expr parser"); }  public static void main(string[] args) {     main mainobj = new main().parseexpr();     }

i using redhat linux 64 bit.

edit:

i ran following command list of dependent libraries:

out of 6 shared libraries, 5 present in these locations: /lib , /lib64
libstdc++.so.6 present in these locations: /usr/lib , /usr/lib64
don't know location searched dependent libraries. tried setting ld_library_path , executed jar follows:

$ export ld_library_path=/lib64:/usr/lib64 $ java -jar -djava.library.path=/home/tomcat/sahithi/exprparser:/lib64:/usr/lib64 expressionparser.jar  $ export ld_library_path=/lib:/usr/lib $ java -jar -djava.library.path=/home/tomcat/sahithi/exprparser:/lib:/usr/lib expressionparser.jar

none of seemed work. got same error before. there else can try? thanks.

that library depends on other shared library isn't present, contains missing entry point.

review installation instructions.
