Re: [WebMacro-user] Help about using webmacro with J2ee

[Eric B. R. <eb...@tc...>]

Hi Jian!   Let me apologize up front.  The WebMacro project is in the =20=

process of moving our mailing lists to SourceForge (should be complete =20=

in the next few days), and you're the first to post to our new =20
SourceForge list.  Unfortunately, our j2ee experts are not on this list =20=

yet.  I'm cc'ing our old list just to see if anyone has any ideas.  =20
Hopefully, if they do, they'll make sure to include the new list in =20
their reponse.

I know little about j2ee, so bear with me...

What I do know about j2ee is that it is supposed to be secure and that =20=

the security policies can be configured.  Is this true?

Anyways, it looks to me as if the java.lang.ClassLoader class (or even =20=

the java.lang.ClassLoader.getSystemClassLoader() method) is something =20=

that cannot be accessed by regular code.  WebMacro does all sorts of =20
loading via the classloader.

I'm wondering if you can expand your security policy to allow access to =20=

(at least) java.lang.ClassLoader.getSystemClassLoader().  Perhaps even =20=

all methods of the class.

Does this help?  I hope it does

eric
