Specifying system properties/security manager for OC4J

Question

I have a couple of related questions regarding OC4J/orion.jar:
1. Generically, how can we specify system properties to orion.jar? Being an executable JAR, simply using -D does not work.
2. Specifically, I need to launch the OC4J app server with a Java security manager (with associated security policies, etc.) Java's way of doing this is via -Djava.security.manager=... but this does not work with executable JARs it seems. I tried specifying these parameters via -D and I got a security exception:
Exception in thread "main" java.security.AccessControlException: access denied (java.util.PropertyP
rmission java.protocol.handler.pkgs write)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.System.setProperty(Unknown Source)
at com.evermind.server.ApplicationServer.initProtocolHandlers(ApplicationServer.java:652)
at com.evermind.server.ApplicationServer.launchCommandline(ApplicationServer.java:319)
at com.evermind.server.ApplicationServer.main(ApplicationServer.java:314)
So, how do I install the Java security manager with orion.jar? Is there any other way to specify system properties to this, or is there any other way to install the Java security manager for OC4J?
Any help much appreciated.

Answer 1

Thanks, that seemed to work. However it seems that spawned another little problem. I was using the -Xbootclasspath/a option while firing up orion.jar because I needed to append something to OC4J's default classpath (that is specified in orion.jar's Manifest). Now, when I start OC4J with the -D options for the security policy, it seems to ignore the -Xbootclasspath argument. I have not yet been able to confirm this fact, but based on the ClassNotFoundError I'm running into, that does seem to be the problem.
So I guess my question is, could specifying the -D options to the executable JAR cause it to ignore any other options you may be passing to it (such as -Xbootclasspath)? Is there any sequence in which these args need to be passed?
Thanks.

Hi,
You can try this :
- Check if you have a file java2.policy in <OC4J_HOME>\config\policy and check if the permission java.util.PropertyPermission "read,write" is granted to <OC4J_HOME>.
if there is no file, you can create one based on <JAVA_HOME>\lib\security\java.policy and grant the approriate privileges.
- Launch OC4J :
java -Djava.security.manager -Djava.security.policy=<OC4J_HOME>/config/java2.policy -jar orion.jar
OR java -Djava.security.manager -Djava.security.policy=<PATH_TO_FILE_POLICY>/<YOUR_FILE>.policy -jar orion.jar
