Re: [Wrapper-user] multiple wrapper.java.liibrary.path statements

[Leif M. <le...@ta...>]

Willy,
    Whenever you encounter problems like this, the first thing you 
should try is to
set the wrapper.debug=true property in the configuration file.   When 
you relaunch
the wrapper you will get a host of useful information, including the 
full command
line used to launch the JVM.   Take a close look at the library path 
that the
Wrapper is generating and make sure that it is what you are expecting.

    UNIX platforms show the command as an array.  For debugging it is 
possible
to copy the command into an empty shell script and launch the JVM manually.
(If you try this, the wrapper.key system property must be removed from the
generated command line.)   This has proved useful mainly as a confidence 
builder
to prove that the Wrapper is or is not the cause of a given problem.

Cheers,
Leif
