Re: [Wrapper-user] Can't read files - security exception

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

Another user had had a similar problem last summer.   It is a permission 
problem.
When you run the app on its own, only your class needs permission, but 
when run
under the java, your class's main method are actually called by the 
Wrapper code.
This means that the Wrapper.jar classes also need to be given permission.

Take a look at this thread:
https://sourceforge.net/forum/forum.php?thread_id=697368&forum_id=122338

Here was the result from that thread:
--------------------
Ok, I got it working. The problem was simply that the wrapper classes 
need to be granted Permission to be able to access the privileged 
classes in the RMI service. I created the following policy file called 
rmiserver.policy:
---
// Give Wrapper classes full permissions
grant codeBase "file:../lib/wrapper.jar" {
permission java.security.AllPermission;
};
---

Then by using the following settings in wrapper.conf, it all seems to 
work correctly.

---
wrapper.java.mainclass=com.silveregg.wrapper.WrapperSimpleApp
wrapper.java.classpath.1=../lib/wrapper.jar
wrapper.java.additional.1=-Djava.security.policy=../conf/rmiserver.policy
wrapper.app.parameter.1=sun.rmi.registry.RegistryImpl
---
All other properties have their default values.
-------------------

Try adding the above to your policy file and write back with the results.

Cheers,
Leif
