java 1.4 fail with java.lang.UnsatisfiedLinkError but 1.5, 1.6 ok

[TsanChung]

My JNI program is working with java 1.5 & 1.6 but fail with java 1.4
on a HP-UX B.11.23 U ia64 computer.
Please help even though java 1.4 is old.

My JNI program is working with java 1.5 & 1.6 but fail with java 1.4
on a HP-UX B.11.23 U ia64 computer.
Please help even though java 1.4 is old.

$ /opt/java1.4/bin/java -d32 -jar jHw.jar
Failed to load MycompAPI and MycompAPI_64 libraries.
java.lang.UnsatisfiedLinkError: no MycompAPI_64 in java.library.path

What this error means is that the library MycompAPI_64 (MycompAPI_64.so
on *nix machines, MycompAPI_64.dll) cannot be found in the library path
for Java 1.4.

If you print out the System property "java.library.path" under all the
versions, you can track down the location of the library and copy it to
the 1.4 library path.

What this error means is that the library MycompAPI_64 (MycompAPI_64.so

the 1.4 library path.

I had done this for java 1.6, 1.5 and 1.4 respectively but it did not
solve "java.library.path" problem.
export CLASSPATH=.:/opt/java6/jre/lib/ext
export SHLIB_PATH=.:/opt/java6/jre/lib/ext

export CLASSPATH=.:/opt/java1.5/jre/lib/ext

export CLASSPATH=.:/opt/java1.4/jre/lib/ext
export SHLIB_PATH=.:/opt/java1.4/jre/lib/ext

I had copied all the required files to /opt/java6/jre/lib/ext, /opt/
java1.5/jre/lib/ext, /opt/java1.4/jre/lib/ext.

java.library.path for java 1.4 is set up as:
/opt/java1.4/jre/lib/IA64N:/opt/java1.4/jre/lib/IA64N/server:/opt/
java1.4/jre/../lib/IA64N:.:/opt/java1.4/jre/lib/ext:/usr/lib

Why java 1.4 still fail?

 

[TsanChung]

Which java version did you compile with?

   BugBear

I compiled with java 1.4.2.08 on another hpux computer and copied the
files to this hpux computer.

The build machine info are:
# java -version

java version "1.4.2.08"

1.4.2.08-050401-17:46)

Check the library path in both cases.

Your native code must be on the library path.

PM Steven Harper is fixated on the costs of implementing Kyoto, estimated as high as 1% of GDP.
However, he refuses to consider the costs of not implementing Kyoto which the
famous economist Nicholas Stern estimated at 5 to 20% of GDP

The library path of java 1.4 & 1.6 are printed by the java program:
System.out.println(System.getProperty("java.library.path"));

/opt/java1.4/jre/lib/IA64N:/opt/java1.4/jre/lib/IA64N/server:/opt/
java1.4/jre/../lib/IA64N:/opt/java1.4/jre/lib/ext:.:/usr/lib
/opt/java6/jre/lib/IA64N:/opt/java6/jre/lib/IA64N/server:/opt/java6/
jre/../lib/IA64N:/opt/java6/jre/lib/ext:.:/usr/lib

My native code is copied to both /opt/java1.4/jre/lib/ext and /opt/
java6/jre/lib/ext.
I do not understand why java 1.4 do not find it but java 1.6 find it.

I do not understand why java 1.4 do not find it but java 1.6 find it.

Problem is solved!
My native code cause load error with java 1.4 but not java 1.6.
Changing the compile options solve this problem.

For me its not working it is working some project but not running for few when I am using already built .so and .h file to create new project and using new shared library.
