LD_LIBRARY_PATH vs jna.library.path

[Damien Gallagher]

Hi

I was just wondering what the difference is between LD_LIBRARY_PATH AND jna.library.path

I am trying to deploy my code onto tomcat on ubuntu but I keep get Unsatisfied Link Errors

I changed tomcat to run as the ubuntu user and added the export LD_LIBRARY_PATH to the .profile file

Also I set the jna.library.path system variable but I am not having any joy

Any help here would be appreciated

Thank you

Damien

LD_LIBRARY_PATH affects the system loader's search, which means _all_ libraries requested to be loaded, including dependencies.  jna.library.path affects only the library explicitly loaded by JNA, and has no effect on loading dependencies.

As a side note, you should have a dedicated tomcat user if you're at all concerned about security.

Run with -Djna.debug_load=true to see the paths that JNA tries.

Thanks Timothy

That is a good suggestion - I have the separate user for tomcat and now I understand the difference in the different variables
