Re: SV: LDAP and EJBs
Thanks Patrik!
There's one issue which still puzzles me. Do I have to write my own
rollback code for LDAP operations when a transaction rolls back? I
browsed the JNDI API and SPI and I couldn't figure out if JNDI somehow
supports transactions (like JDBC does with begin(), rollback() and
commit()).
If my code is following for instance:
UpdatingFacadeEJB implements SessionBean {
public void doTheUpdate() {
ldapDelegate.writeLdapEntry();
rdbmsDelegate.writeRdbmsRow();
}
}
Let's say that ldapDelegate.writeLdapEntry() succeeds but
rdbmsDelegate.writeRdbmsRow() fails by throwing an EJBException. In this
case can the container's transaction manager somehow rollback the LDAP
operations done earlier in ldapDelegate.writeLdapEntry() method?

You would have one sessionbean being business delegate in front of the
EntityBean manipulating the RDBMS and another managing the LDAP

sessionbeans with one method that does the whole trick with
transactional attributes set up to require a transaction before
entering the method.
interface UpdatingFacade : SessionBean {
void doTheUpdate() throws RemoteException;
}
interface LdapDelegate : SessionBean {
void writeLdapEntry() throws RemoteException;
}
interface RdbmsDelegate : SessionBean or EntityBean {
void writeRdbmsRow() throws RemoteException;
}
Then you want an error in the writeLdapEntry() aswell as the
writeRdbmsRow() to throw an EJBException breaking the transaction
begun by doTheUpdate() method. Both writeXxx methods must require that
a transaction already exists before being called. The doTheUpdate()
method can really have it either way, as long as there is an active
transaction associated to the thread calling it.

Ämne: LDAP and EJBs
Hi everyone!
I have a use case where I need to interface an LDAP directory and a
relational database within a same transaction. That is, to create a
new
row to RDBMS from session bean using entity bean and to create an LDAP
entry from the same session bean using Sun's LDAP provider through
JNDI.
1. Is this possible?
2. Can I use container managed transactions?
Thanks a lot!

Registering EJB's on the fly
Dear All, I'm wondering how I can register EJB's on the fly in Orion. Say I have a bean that is registered and known. As the program runs I decide I also want it registered under a different name in the JNDI registry. thus, in pseudo code: BeanBHome b = lookup(ejb/BeanB); // ok, fine BeanBHome c = lookup(ejb/BeanC); // *agk!* fails jndi.register(ejb/BeanC, BeanBHome); BeanBHome c = lookup(ejb/BeanC); // ah, now it works! Is this possible? Kees Jan You are only young once, but you can stay immature all your life.

HOT deployment ??
I still don't understand when my changes are NOT picked up ?? During development I don't have a ear file, I just have a dir with all the classes/xml files. Untill now, when I change something in an EJB class, I have to stop orion, delete the deployment dir en start again Why like this ?? As if I do it the other ways, like: + using the admin.jar tool, something like: java -jar /opt/Orion/admin.jar ormi://localhost admin pass -deploy -file /opt/Orion/applications/sgs.ear -deploymentName sgs + touching the xml files in the META dir (the orion signals an update). + Removing the deployment dir during operation... it gives Java Exception: Broken pipe errror... If I do it like above it ofter occurs that it doesn't pick up my changes. Also when I replace a class that is not part of the EJB's, which it loaded during runtime, it still keeps on using the old class... what am I doing wrong It can't believe that is can't be done more simple!!?? BTW: when I do a: ++ java -jar /opt/Orion/admin.jar ormi://localhost admin pass -restart, I do get: -- Recovery completed, 0 connections committed and 0 rolled back... Orion/1.5.1 initialized Restarting... Error starting JMS-Server: Unable to bind socket: Address already in use Error starting RMI-Server: IO Error: Address already in use - ++ The shutdown command does work however. So please some advices on what I am doing wrong, and how I should do it (do I needs to change some JVM settings ??). I am running RedHat 7.0. Eddie
FYI: XML parsing and orion server woes solved
I have discovered a neat way to have my cake and eat it too. The problem: Orion is configured (via an include in the jar file) to use crimson. Crimson doesn't support schema and adding xerces to the lib directory makes no difference at all. I didn't want to hack the orion.jar file as this will be wiped out the next time I upgrade. The solution: Download the latest xerces.jar from http://xml.apache.organd replace it in the orion directory. Next replace the crimson.jar file in the orion directory with the one attached to this message. Voila! All I did was make a crimson.jar file that contains a manifest file with an include for xerces.jar and two JAXP config files that setup xerces as the default JAXP parser. Really orionserver should probably just come configured to use the latest xerces anyway but until that time, here is a relatively elegant work-around. Hope this helps. Regards, Simon. crimson.jar
rmi question
I have found that instantiating a class with a static member to manage a pool of application connections (to a proprietary host app) does not work, because passivated beans, when activated do not get the static member from the current running vm, but an empty one. That's life in EJB servers and I'm not confused about that. (just using the static class violates the EJB standard... ). After reading a lot of email archives I gather that it is necessary to create an RMI server to accomplish a single interface to this object fro all the EJB's in the app (potentially clustered). That's nice, but I have to know how to do several things: -package the rmi server component in the ear -start the server when the app starts or start it from within the first session bean. Is this possible? If I implement an RMI server will I now have a nightmare of configuration requirements to get my app to work on a variety of servers? Thanks Wendell Nichols

RE: communication among ejbs in different applications
Hi, Juan: Thank for your help. In fact, recently, we tested several combinations of App a and App b. ( Becasue the parent attribute is only for Orion, we gave it up.) And, also we tested the context solution by using JNDI. The results are : Senario 1: If we put the appA.jar in the classPath of appB, and put the appB.jar in the classpath of appA, we can pass the compiling sucessfully, but got Class not defined error when we tried to initialize a context in one EJB in App A to look up the EJB in App B; If we forced the App A to jar with App B, so the appA-ejb.jar file contains both App A classes and App B classes. In this way, we did see the all ejbs in App B via context, but when we cast it, we got CastException error message. Still the old question, can we make this kind call? Thanks!

The entire site works, but I can't hit it via https.

RE: help...Error deserializing session
Sounds like you have a stateful session bean that has a member variable which is of a non-serializable type, from the looks of it, some sort of JDBC object, such as Connection or Statement. When your bean is activated or passivated, it's trying to serialize or deserialize that member variable causing the error. Declare the offending variable as transient, and ensure that you initialize the variable before you use it in your code.

Have you tried using the tunnelServlet to pass all static requests to Apache? Its a little bass-ackwards, but orion could be faster than apache in this respect. Also, are you running orion, the loadbalancer, and apache on the same machine? This could be just a load issue. Lastly, orion is generally faster than apache at serving up static content. There are very good reasons for using apache for static content, though, that have nothing to do with speed.
