Calling entity bean from a session bean in Orion 1.5.3
Hi, I want to access an entity bean from a session bean . I have added the ejb-ref tag in the ejb-jar.xml and the same works perfectly on orion 1.3.8 But on Orion 1.5.3 I get the following error javax.naming.NamingException: No EJB found with an ejb-name matching the ejb-link 'Entity' at com.evermind[Orion/1.5.3 (build 10509)]._ccb._po(.:64) at com.evermind[Orion/1.5.3 (build 10509)]._lsb._wk(.:33) at com.evermind[Orion/1.5.3 (build 10509)].server.rmi.RMIContext._ywd(.:857) at com.evermind[Orion/1.5.3 (build 10509)].server.rmi.RMIContext._xnb(.:660) at com.evermind[Orion/1.5.3 (build 10509)].server.rmi.RMIContext.lookup(.:63) at com.evermind[Orion/1.5.3 (build 10509)]._bl._eh(.:189) at com.evermind[Orion/1.5.3 (build 10509)]._bl.lookup(.:63) at com.evermind[Orion/1.5.3 (build 10509)]._ccb._po(.:34) at com.evermind[Orion/1.5.3 (build 10509)]._in.lookup(.:53) at com.evermind[Orion/1.5.3 (build 10509)]._bl._eh(.:121) at com.evermind[Orion/1.5.3 (build 10509)]._bl.lookup(.:63) This is my ejb-jar.xml session display-nameA/display-name ejb-nameA/ejb-name homeAHome/home remoteA/remote ejb-classABean/ejb-class session-typeStateless/session-type transaction-typeBean/transaction-type ejb-ref descriptionSubscriber EJB/description ejb-ref-nameejb/BHome/ejb-ref-name ejb-ref-typeEntity/ejb-ref-type homeBHome/home remoteB/remote ejb-linkEntity/ejb-link /ejb-ref /session Please advice.

java.lang.OutOfMemoryError;
Hi , We get java.lang.OutOfMemoryError; on production server frequetly.I know this problem was discussed in this list before. I implemented all the sugestions in this mailing list but still the error keeps on coming .I would like to know the following 1) As an answer to the above mentioned problem I saw a sugestion in this mailing list to limit the # of instances by adding max-instances attribute to orion-ejb-jar.xml which would force orion to passivate less used beans.I downloaded orion 1.5.2 and set the same.But observed that passivation is never called. Is there a way to make sure that orion passivates beans which are not used . 2) Some people have mentioned increasing the memory. Has any body tried this solution and i would like to know whether the problem got solved.How can I increase the memory ? 3)Has anybody solved this problem ? Any sugestions Thanks in advance Regards Rajeev

Has any body tried this solution and i would like to know whether the problem got solved.How can I increase the memory ? first, by hardware (buy some chips), secondly, by specifying a minimun/maximun heap size of the JVM when you invoke it these are the ones I use (W2K, Sun's JVM 1.3.0) -Xms128m (minimun heap size 128 MB) -Xmx320m (maximun heap size 320 MB) 3)Has anybody solved this problem ? No. There´s always a limit to the amount of memory available on any given system ;-) Let's hope that(buggy orion code) gets fixed soon- don't forget to cast your vote on Bugzilla, that is, if vote casting is finally enabled Any sugestions Thanks in advance Regards Rajeev
Orion as Win2000 service using jnt !
Hi Friends I am trying to set up Orion as a Win2000 Service. First I tried to set it up using RunExecSvc.exe as explained in orionsupport.com. But I was not successful in getting this exe run as it always exited suddenly. Then taking a hint from this mailing list I tried with jnt. D:\jntd:\jnt\jnt "/InstallAsService: Orion" "/SDD:\orion" java -jar d:\orion \orion.jar I get the following statements. Java Service Launcher V1.0.1 beta Copyright (C) 2000 by eWorkSmart, LLC 04/17/01 17:04:40 - Installing as service "Orion" (Orion). 04/17/01 17:04:40 - This has been installed as "Orion". This service is set to automatically start when the system boots. To start the service now, use the "Services" icon found in the control panel. 04/17/01 17:04:40 - NT Service options: Use /InstallAsService:ServiceName[:dependent1,dependent2,...] to install. Use /RemoveAsService:ServiceName to remove (uninstall) as a service. Use /SetServiceParams:ServiceName to change the startup parameters for this serv ice. Note: Any additional parameters on the command line will be setup as the startup parameters for the service when using the /InstallAsService or /SetServiceParams options. But after starting the Orion Service from Services, When I try to access the application then it throws an error saying web server can not be found. Any idea why this is happening ? Thanks and Regards Rajeev

I was experiencing the same kind of trouble just the other day. May fault
was in implementing the PK class I had forgot to implement the equals and
the hashCode methods, hope it helps.
Example of one of my PK classes:
package knut.ejb.entity;
public class UserContactPK implements java.io.Serializable {
public String ownerId;
public String contactId;
public UserContactPK(String ownerId,String contactId) {
this.ownerId = ownerId;
this.contactId = contactId;
}
public String getOwnerId() {
return ownerId;
}
public String getContactId() {
return contactId;
}
public String toString () {
return ownerId+":"+contactId;
}
public boolean equals(Object other) {
if (other instanceof UserContactPK) {
return ownerId.equals(((UserContactPK)other).ownerId)
contactId.equals(((UserContactPK)other).contactId);
}
return false;
}
public int hashCode() {
return ownerId.hashCode();
}
}

calls ejbload for each request.(Bean is yet to be passivated).Can any body
