Clairifcation on EJB's Invoking Non-EJB's in App server
I am wondering if you someone from Team Sybase could clarify something for
me. In a note below
Jonathan Baker replyed to this group saying that the CORBA method on calling
a PBNVO from an EJB was the "long way around" and directed the individual
with the question to follow the procedure outlined in Chapter 9 of the
Jaguar Programmers Guide "Invoking Non- EJB components from an EJB".
What would be the pros and cons of either approach? And do you have an idea
as to why the Jaguar documentation would only refer to to using the EJB
stubs ?

EJB's Calling EJB's and Authentication Problem
I have a web application in EAServer 4.1.3. The user is forwarded to a servlet within my web application which connects to EAServer and authenticates them before forwarding them to a JSP page. The JSP page makes a call to a Session Bean also in EAServer. From my Session Bean I then make calls to another session bean. If i use the following code it does not work, it fails to find the second bean, presumably at authentication because I get the following error: javax.naming.Context ctx = new InitialContext(); Object obj = ctx.lookup("Package/Component"); ComponentHom...
EJB's and PB NVO's
We are currently on a migration path to full J2EE. Today we have a number of PB NVO's and now we are slowly converting them to EJB's. It is going to be impossible to convert everything to EJB's in one release. So, we are developing a migration plan. My question is, what is the best way to call a PB NVO from an EJB. Should I use the sessionManager? Or is there better method to instantiate NVO'? Short code samples would be a great help. Thanks in advance for the help. -mark Generate EJB stubs for the PB NVO and call them like they were an EJB. Now when a...
When EJB's and ASP's collide...
I'm working on a design for a "single sign-on" architecture. What I have in mind is an EJB with methods that use JNDI to talk to an LDAP server to return either a string that indicates a user's security profile for a given application or name/value pairs indicating the users security profiles for all supported applications. Some of the applications using this might be built on Active Server Pages. Is there any support for ASP clients to EJB's? If not I'm thinking about a PowerBuilder component that can be called from an ASP via CORBA and act as a bridge to...

NtCanuck's `TreeWalk' and AnalogX's `FastCache' Dns Servers
Hello Global Friends, I have been using AnalogX's "FastCache" software as my Local Dns Server for all these years. For the last three years I did not see a new version of FastCache software.

Who's show is SN? Steve's or Leo's?
