problem with jdk version [message #74290]

Hi,

I'm trying to integrate the osgi framework as a service in a project. I'm
working with a proprietary VM, which is compliant with jdk 1.1, although
it implements all the API's upto jdk 1.3. It does not support the java 2
security model. When I try to load the framework onto my emdedded device,
I get the following exceptions:

java.lang.NoSuchMethodError:
java/lang/Class.getProtectionDomain()Ljava/security/Protecti onDomain;
at
org/eclipse/core/runtime/adaptor/EclipseStarter.initializePr operties()V
(EclipseStarter.java:1336:49)
at
org/eclipse/core/runtime/adaptor/EclipseStarter.startup([Lja va/lang/String;Ljava/lang/Runnable;)Lorg/osgi/framework/Bund leContext;
(EclipseStarter.java:272:33)
at
org/eclipse/core/runtime/adaptor/EclipseStarter.run([Ljava/l ang/String;Ljava/lang/Runnable;)Ljava/lang/Object;
(EclipseStarter.java:173:37)
at
org/eclipse/core/runtime/adaptor/EclipseStarter.main([Ljava/ lang/String;)V
(EclipseStarter.java:150:42)

I was wondering if I could use the existing implementation of OSGi or I
could download a previous version of eclipse?

Thanks,
Rohit.

Those classes are through out most OSGi implementations as security is a
fundamental part of the spec. Not sure what you can do here. I would
have thought that that method would be on Class if it is a 1.3
implementation...

Unfortunately, this was something added in Java 1.2. Given that your VM does not support the Java 2 security model, and that your VM is a 1.1 vm (regardless of what other APIs might be available), it's very likely that the Class object does not support this method, and that therefore there's not much you can do about it. EclipseStarter needs to have a 1.2 VM+ IIRC to run, since it calls getProtectionDomain().

http://java.sun.com/j2se/1.3/docs/api/java/lang/Class.html#g etProtectionDomain()

Note that if you supply the framework (or system path) then this piece of code doesn't get triggered. You might try to run it with -Dosgi.framework=/path/to/ or -Dosgi.syspath= to specify the location of the (OSGi) plugins.

This might not work; that's just based on an eyeball of my understanding of the code.

Thanks for reply!

I just skimmed through the OSGi specs and my guess is we should be able to
disable the security model by given AllPermissions to all the modules. Am
I right?

If there is a way to disable the Java 2 Security model, can you please
send me some pointers on how to do it?

Thanks again!

It's not the permissions -- it's the fact that Java 1.1 doesn't have this method, so doesn't exist on the Class object. So no, you can't do what you're suggesting as it doesn't make sense. I suggest that you use a more recent VM.

Not really sure what to say here. AFAIK you have to do something
special to make security be turned on. So, "don't do that" :-) Not
alot of help...
