[Wrapper-user] Security errors with the wrapper and Jini

[Jos M. <jos...@ho...>]

I'm trying to use the java service wrapper to automatically start a number 
of jini services on both NT and Linux. I've successfully managed to get the 
java class server configured, but I've run into some problems with 
jrmp-phoenix which is the replacement for RMID.

I'm using the WrapperSimpleApp starter and am receiving a 
java.lang.IllegalAccessException error when the wrapper tries to invoke the 
main method of phoenix.

This error appears very similar to one posted to this group on 2003-10-27 
23:16 by Alan Parry thought the suggestion of incorrect jar placement in 
that post doesn't apply here (I think).

To reduce the problem to use of WrapperSimpleApp I've executed the following

java ^
-cp lib\wrapper.jar;lib\start.jar;lib\phoenix.jar ^
-Djava.security.manager= ^
-Djava.security.policy=config\jsk-all.policy ^
    org.tanukisoftware.wrapper.WrapperSimpleApp ^
    com.sun.jini.start.ServiceStarter ^
    config\start-jarserver.config

from a directory that contains lib and config. The jsk-all.policy file 
contains

grant {
	permission java.security.AllPermission;
};

And this sucessfully fires off the java class server

However

java ^
-cp lib\wrapper.jar;lib\start.jar;lib\phoenix.jar ^
-Djava.security.manager= ^
-Djava.security.policy=config\jsk-all.policy ^
-Dwrapper.debug="TRUE" ^
    org.tanukisoftware.wrapper.WrapperSimpleApp ^
    com.sun.jini.phoenix.Activation ^
    config\jrmp-phoenix.config

which ought to do much the same with phoenix produces

Wrapper Manager: JVM #1
Wrapper Manager: Registering shutdown hook
Wrapper Manager: Not using wrapper.  (key not specified)

I wonder if anyone has experience of what policy settings might have gone 
wrong here?

Many Thanks

Jos

[Kumar S. <ku...@ho...>]

I had also got a similar error a couple of days ago. But I noticed that when
I moved the main method to another class containing just the main method, it
worked fine. Try it out and let us know if this workaround works for you or
was it just something specific to my setup.

Thanks,
Kumar

Re: [Wrapper-user] Security errors with the wrapper and Jini

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

Jos,
This looks like a problem with your policy file. I cover this very
briefly on the
following page:
http://wrapper.tanukisoftware.org/doc/english/faq.html

Try specifying the wrapper's jar file explicitly as follows:

// Give Wrapper classes full permissions
grant codeBase "file:../lib/wrapper.jar" {
permission java.security.AllPermission;
};

That has worked for me in the past with RMI.

As I said in that thread you mentioned. Placing the wrapper.jar into the
Java ext directory ill work because the jar will be views as one of the
JVM's
own privileged jars. But doing that is not advised. For a number of reasons,
it is best to do everything possible to avoid changing the contents of the
JVM's directory. It will lead to all kind of problems when other programs
are run using that JVM, and it makes installing the app on other machines
that much more complicated.

Post back with results.

Cheers,
Leif
