Need some help to implement Clustering
Hi, I am unable to implement session failover in orion1.5.2 , getting 'Error while receiving sessions from the cluster'. SETUP: I have 2 win2k servers running jdk 1.3.0_02 and jikes 1.15 with Orion1.5.2. The servers have ids 82 and 83. PROBLEM: Both 82 and 83 are up, I go to page1.jsp and then to page2.jsp, I see session being created and all the values that are being sent to the other server in the same island(1). If my session is in 83 and when I bring 83 down, my session is transferred to 82. Perfect. Page2.jsp has a counter similar to sessionServlet. When I bring up 83, everything works fine in the web site, However I looked at the logs and I found this error 'Error while receiving sessions from the cluster' in 83(see below). I am also attaching the bean and both the jsp pages. I am just curious, when you use a Java Bean, shouldn't you see a *.ser file in the persistence directory of the application?. I have also attached(see below) the out.log just in case you notice anything else. *** application.log_83 3/19/02 11:27 AM Started 3/19/02 11:27 AM config-web-app: 1.5.2 Started 3/19/02 11:27 AM config-web-app: 1.5.2 Stopped 3/19/02 11:27 AM Stopped (JVM termination) 3/19/02 11:28 AM Started 3/19/02 11:28 AM config-web-app: Error while receiving sessions from the cluster java.lang.ClassNotFoundException: com/micronpc/util/ChannelUtilityBean at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at com.evermind._dp.resolveClass(Unknown Source) at java.io.ObjectInputStream.inputClassDescriptor(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at java.io.ObjectInputStream.inputObject(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at com.evermind.server.ApplicationServer._wy(Unknown Source) at com.evermind.server.http.EvermindHttpSession.readObject(Unknown Source) at com.evermind.server.http.EvermindHttpSession._hy(Unknown Source) at com.evermind.server.http.ClusteredHttpSession._hy(Unknown Source) at com.evermind.server.http.ClusteredHttpSession._hy(Unknown Source) at com.evermind._ah._toc(Unknown Source) at com.evermind._cqb._tfc(Unknown Source) at com.evermind._cqb._os(Unknown Source) at com.evermind._hr.run(Unknown Source) at com.evermind._if.run(Unknown Source) 3/19/02 11:28 AM config-web-app: 1.5.2 Started *** out.log for server 82 * HTTP-clustering service started...

RE: problem in accessing ejb from a bean in web-inf/classesdirec tory .
I tried the following 2 ways and get the same error:
Object hdrObj = cntx.lookup("java:comp/env/B2BOrderHeader");
headerHome = (B2BOrderHeaderHome)
and
headerHome = (B2BOrderHeaderHome)cntx.lookup("B2BOrderHeader");
error:

The line 142 is:
headerHome = (B2BOrderHeaderHome) cntx.lookup("B2BOrderHeader");
Thanks in advance for your help

I think I remember vagely a thread in this list about java:comp/,
but that was 3000 messages ago :). Anyway, this works fine for me.

problem in accessing ejb from a bean in web-inf/classesdirectory .
Hi,
I have an ejb installed in my local orion server(ver 1.4.0).I can
access the ejb from a standalone application and everything works great.I
created a java bean(called OrderBeanWrapper) which gets the initial context
and does a lookup of the ejb.When I attempt a lookup , I get a Naming
Exception.
The error description is as follows:
javax.naming.NameNotFoundException: B2BOrderHeader not found in
defaultWebApp
at com.evermind.util.t.lookup(JAX)
at com.evermind.server.hl.f3(JAX)

The java bean is called from a jsp.Lines 136 and 137 are as follows:
Object hdrObj = cntx.lookup("java:comp/env/B2BOrderHeader");
headerHome = (B2BOrderHeaderHome)
javax.rmi.PortableRemoteObject.narrow(hdrObj,B2BOrderHeaderHome.class);
Thanks in advance for you help
