A client calls several applications ?
Hi, I 'm using an orion application server on which is deployed 3 applications. I've got a problem when a client try to use these applications. The client call a bean of the first application, and after calls differents beans of the second application. There is sometime a problem during the call to the second application. This problem is not systematic... Let 's see the message : rulbok and acs are the name of my applications On the client : Exception passing by from remote server: com.evermind.server.rmi.OrionRemoteException: Disconnected: Protocol error: invalid domain for this connection: rulbok com.evermind.server.rmi.OrionRemoteException: Disconnected: Protocol error: invalid domain for this connection: rulbok at com.evermind.server.rmi.RMIConnection.disconnect(RMIConnection.java:1769) at com.evermind.server.rmi.RMIConnection.run(RMIConnection.java:541) at java.lang.Thread.run(Thread.java:539) On the server : Read command: 8 Read command: 25 Disconnected: Protocol error: invalid domain for this connection: acs Disconnected: Protocol error: invalid domain for this connection: acs What is very surprising is that the client sometime continue and sometime is frozen Thanks for your help. -- Rémy--
EJB from an Applet
Hi all, I'm developing an application using swing that executes remotes EJB.

Orion 1.5.4 changes '.' to '_' in table specification in orion-ejb-jar.xml
When we are trying to deploy an existing .EAR file to Orion 1.5.4, Orion changes the orion-ejb-jar.xml file in a way that makes the deployed CMP entity beans to fail: The tables are situated in a database on a AS400 server, and when connecting from the app-server we can not log on with the 'user' owning the tables. Because of this, our orion-ejb-jar.xml specifies the tables to be used by entity-beans like: table=dtks000.quote When starting Orion, this is now changed to: table=dtks000_quote which does not work. This is not the same behavior as in Orion 1.5.3. Is there anyone who can tell me whats wrong? regards, Trond Rønneberg, Mogul Technology _ Join the worlds largest e-mail service with MSN Hotmail. http://www.hotmail.com

Re: BMP Entity Bean Performance Problem
Tim,
As I am not sure of the exact nature of your entity beans, I can't give
you any detailed suggestions, but many people impement a 'dirty' flag in
their code.
eg:
void setName(String name)
{
dirty=true;
this.name = name;
}
ejbStore()
{
if (!dirty)
return;
else
{
doUpdate();
dirty=false;
}
}
This limits the number of updates that you are doing.
I assume that you have a very good reason for using BMP, but I would
suggest that you use CMP where possible. The performance benefits are
quite large.
Cheers,
Scott

Hi
I am using JSP (client) and BMP Entity beans (for mysql db) in my
application. I am having a few problems in terms of performance.
1. When I call homeObject.findAll() for the first time, ejbLoad() is invoked
for every row in the database. I know this only happens once so I can
tolerate this but I am open to suggestions.
2. Once the entity beans are loaded, I call
homeObject.findByPrimaryKey().getSomeAttribute(). This calls ejbStore() for
every row in the database as well. This is not acceptable as the EJB is
performing UPDATE * number of rows in DB.
I tried to solve this by implementing a stateful session bean acts a middle
layer between JSP and entity beans. However, the problem still exists
My session bean code:
public class PubcompanyManagerBean implements SessionBean{
private SessionContext context;
private PubCompany pubcompany;
private PubCompanyHome pubcompanyhome;
public void ejbCreate() throws NamingException, RemoteException {}
public void ejbRemove() {}
public void ejbActivate() {}
public void ejbPassivate() {}
public void setSessionContext(SessionContext sc) {
context = sc;
}
// Business logic methods
public Collection getAllPubCompanies() throws NamingException,
RemoteException, FinderException {
Context context = new InitialContext();
pubcompanyhome = (PubCompanyHome)PortableRemoteObject.narrow(
context.lookup(java:comp/env/crm/PubCompany), PubCompanyHome.class);
Collection companyList = pubcompanyhome.findAll();
return companyList;
}
public PubCompany getPubCompany(String companyid) throws NamingException,
RemoteException, FinderException {
Context context = new InitialContext();
pubcompanyhome = (PubCompanyHome)PortableRemoteObject.narrow(
context.lookup(java:comp/env/crm/PubCompany), PubCompanyHome.class);
