Problem With System.load( )

nallamolu — Wed, 14 Jan 2009 11:18:19 GMT

Hi World,

I have a senario where
System.load("absolute Path to a .so file" ); works fine for one application & it fails for another senario of System.load("absolute Path to same .so file" ) of another application ?

1.)

String s = "/home/nalgo01/Probeing/libHpuxItanium64Stats.so"
System.out.println(System.load(s));

This senario works fine for one appication.

2.)
The same procedure for other ( same adsolute path for .so ) application fails.

It is giving error as
Error: java.lang.UnsatisfiedLinkError: Can't load library: /home/nalgo01/Probeing/libHpuxItanium64Stats.so

What may be the reason for this.

Why the same .so file being loading on one application and why it is failig on other application

Any help is appreciable.

Thanking you,
Gopi

From the info you give, I would think the problem is with routines/functions which are used in the .so which are not loaded in option 2, while they are available for option 1. But more tracing info might us help you solve this.

Thanks for u r reply,

It is the same .so file which is being used.
Functions/routins are also the same which are used in both application.

Thanking you,

>Error: java.lang.UnsatisfiedLinkError: Can't load library: .../libHpuxItanium64Stats.so

Again a useless error message without details.

>Functions/routines are also the same which are used in both application.

You exercise the same paths in each?

>Elmar: I would think the problem is with routines/functions which are used in the .so which are not loaded in option 2

This could be due to -B deferred. Where the second case calls more functions.

>But more tracing info might us help you solve this.

What kind of tracing, java?
