Category: Integration
Status: Closed

Severity: MEDIUM
Reported against release: 0.8
Fixed in release: 0.8.2 (Beta Refresh 2)

PROBLEM:

The Jini-Browser.xml file in the openwings-0.8\bin directory is a 
component descriptor that is intended to allow users to run the jini 
browser program. However, it does not work when started in the shell 
with a "process -start", or with owrun.  

The following error occurs:

java.lang.SecurityException
	at 
com.mot.openwings.container.jvm.ContainerJVMSecurityManager.checkPermiss
ion(ContainerJVMSecurityManager.java:173)
	at java.lang.System.setSecurityManager0(System.java:222)
	at java.lang.System.setSecurityManager(System.java:214)
	at com.sun.jini.example.browser.Browser.main(Browser.java:1322)
	at com.sun.jini.example.browser.Browser.main(Browser.java:1340)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
	at sun.reflect.NativeMethodAccessorImpl.invoke
(NativeMethodAccessorImpl.java:42)
	at sun.reflect.DelegatingMethodAccessorImpl.invoke
(DelegatingMethodAccessorImpl.java:28)
	at java.lang.reflect.Method.invoke(Method.java:313)
	at com.mot.openwings.container.jvm.ProcessMainThread.run
(ContainerJVMProcessThread.java:486)

This ComponentDescriptor should match the version embedded in the 
ContainerManagerPolicy.

Verify on a build dated 12/14/01 or later.

ANALYSIS:

The Jini browser cannot run inside an Openwings container because it 
attempts to set a SecurityManager without first checking to see if one 
is set. The container SecurityManager disallows the Jini-browser's 
request to change the SecurityManager, and the Jini-Browser program 
cannot recover from this. 

The solution is to run the Jini-browser as a standalone program.

WORKAROUND:

Edit the Jini-Browser.xml file, and change the value 
of "sharedContainerHint" flag to "false".
