Re: Writing custom Resource Manager
I am also interested whether this can also be performed. Evan Vaala Vidur Dhanda wrote: Hello, Is it possible to write a custom resource manager in EJB1.1 and Orion? Much like EJBs can use a DataSource, I would like to write an application specific resource manager. How can I do that? Thanks, Vidur PS. If possible, please cc me the replies.

Retrieving EJB's across platforms
I am having a problem calling EJB's across platforms. I created a routine in
jsp(temporarily) from the coded supplied to this group by Jens Stutte(Thank
you!) in a previous posting. I have EJB's called "inventory" on two different
boxes. My main Orion server is running on local host. This Test.jsp on
retrieves the context from server xyz.xyz.xyz.xyz. However when I retrieve the
"home" inventory be it keeps pulling in the "home" inventory bean from local
host.
However, on xyz.xyz.xyz.xyz as a test I bound in foo=bar( ctx.bind("foo","bar")
) and I am able to(from localhost) retrieve that value from the xyz.xyz.xyz.xyz
server. See code below.
Am I doing something wrong? Or might this be a bug.
Both xyz.xyz.xyz.xyz have the inventory ejb loaded. They do use the same
interfaces, but the InventoryEJB classes are coded differently.
Any help would be appreciated!
Thanks!

Server.xml classpath problem - 0.9.1c
I posted this earlier in the week. It still doesn't seem to work in 0.9.1c.

I just upgraded to 0.9.1 and I'm having problems with my library path entry
in server.xml. I noticed that the format of this tag has changed slightly,
so I simply copied my list of jars (delimited by ;'s) from my 0.8.2
server.xml to the 0.9.1 server.xml, but it is unable to find a class that
0.8.2 had no problem finding. RH Linux 6.1, Sun JDK 1.2.2 RC2.
I am having the same problem. In my case I have narrowed it down to be only
classes that are defined in a VariableInfo object when subclassing a
TagExtraInfo class. The only work around that I have found at this point is to
jar the needed classes into orion.jar.
As Jeff mentioned, the library path did work ok in 0.8.2, but not in 0.8.3 and
above.
Here is a snip of my code and the error message:
public class PageIdTagExtraInfo extends TagExtraInfo {
public VariableInfo[] getVariableInfo(TagData data) {
return new VariableInfo[]
{
new VariableInfo(data.getAttributeString("id"),
"ra.web.PageId",
true,
VariableInfo.AT_END),
Error returned from Browser:
