Re: Very Strange problem with a static varible on a jsp
I see what you mean. So it seems that the only solution to be sure a class is not unloaded is to make your own class loader for that class.

Problem in custom User Managers !!!
Hi All I am trying out my hands on using a custom user manager for user/groups in orion for ejbs. This access to the ejbs is defined in the orion-ejb-jar.xml at the method level. i.e. we are giving method permissions for the ejbs in ejb-jar.xml file. Also the orion-application and orion-ejb-jar.xml have been configured for the same. Now i added the group names (though not actually required) to the principals.xml and tried to access the ejb methods through a java client. But orion throws a security exception, even if valid user name is provided. It's basically failing to recognise/read a group name and validate the users against the group. The inGroup(username, groupname)/isMemberOf() method in my custom user manager ( derived from SimpleUserManager from orionsupport.com) does not get called at all!! Do I need to override the methods(like getGroups..) of the UserWrapper class ( implementing User) in SimpleUserManager class? The whole problem started when I shifted from a web application to a simple java client accessing ejbs... Please help... Thanks in advance Yash Get 250 color business cards for FREE! http://businesscards.lycos.com/vp/fastpath/
RE: Problem in custom User Managers !!!
The security exception that is being thrown through rmi is because of the default rmi restriction that only administrators have access to rmi. If you have created a custom user manager, and not created an administrator user...this will cause the exception. Try this...startup up the orionconsole, and try to quary your ejb's. If you can see them, but you can't get any queries, you will see the response that the password/username doesn't work. If this is the case, you need to change the default rmi security from administrator to one of your default groups for your usermanager. I hope this helps...

Re: Directory Listing
You could use the java.net.URL class from your servlet to get the directory listing that is produced. Then you can process that however you like. The snag is that you would have to have the servlet at a different URL. In other words, if http://foo.com/ gives you the directory listing, you would have to put the servlet at (say) http://foo.com/prettyList - because if you arranged to have it served from http://foo.com/ it would be trying to read its own output, which would get it rather confused, I'd think.

Class Reloading in Web-Apps
What are the capabilites of Orion in terms of class reloading, in relation to a deployed web application, while the server is running. If you change a java file, and recompile it to the ./WEB-INF/classes directory, should Orion not detect the change and use the new class? Are there any restrictions on whether the class is reloaded depending upon it's serialization to a session? Thanks. ./ted

But there has not been any >problem except CLOB problem up to now. Interesting. No problems handling CLOBs here except when using a Type 1 or 2 driver. It seems in JDK 1.3.x Sun is preventing sharing of the c++ library for one reason or another, which means you can only load it once, which means that your connection pooler can only be used once on the machine for all your apps. What we did was move everything to the Type 4 driver (Thin client), and write code to handle CLOB insert/updates through Oracle's DBMS_LOB procedures. The only trick to it is that every time you want to update a CLOB, you have to re initialize it with EMPTY_LOB(), then do the update with the new data. If you don't do that you will end up with incorrect data. The data 'corruption' if you don't do the EMPTY_LOB() manifests itself in the form of old data over new data. This is because when you do an update, and the number of bytes in the data is smaller than the number of bytes in the original data, the CLOB will get updated with the new number of chars, but anything over that remains in the CLOB column. YUK. Of course if anyone knows another way around this please let me know :-) Hope this helps. R Robert S.
