pitfalls migrating an app from orion to wls
Hi, just wanted to ask the list if anyone has migrated a compley app from orion to weblogic. we have a customer who wants us to port an app we developed for them from orion to weblogic (corporate policy). so far we have identified security (we have used orion security APIs) and cmp (we use EJB1.1 CMP and weblogic's capabilities in that area really suck) as two areas that need some work. any experiences anyone would like to share? thanks in advance robert p.s.: I sent this message yesterday but it didn't make it through.

Like Statements in orion-ejb-jar.xml
I would like to perform like Statements in finder methods. Therfor I changed in the orion-ejb-jar.xml the sql Statement to where xxx like ? ! But Orion always overwrites it to where xxx = ? Is there a way to use like statements in Orion or do one have to use sql Queries? Thanks Michael

100 Continue
Hi Im having a propblem sending a POST to a servlet in orion Im trying to send a POST from a PDA with Windows CE installed The servlet just parses the stream and stores the content in a database When the POST is submitted, everything after the 100 Continue response is being stored in the database The data sent before 100 Continue is somehow lost When I try to send the same POST data from an JAVA app, everything is stored in the database and it works fine It seems to me that the PDA client cannot handle the 100 Continue response and continuing sending the POST data and orion is not able to receive it Has anyone any sugesstions? By the way Im using mac OSX with orion 152 Has anyone been able to run a J2EE app with orion 154? Im getting a JVM error (segmentation fault) just by starting it Havent tried with the new MRJ 131 though regards /Linus
RE: pitfalls migrating an app from orion to wls
Hi Robert, indeed many posts seem to just disappear on here, but the guys at Ironflare are working to fix that... In the meantime, I just wanted to offer that I work for a company that develops what we call Portal Lifecycle Management tools (read application lifecycle for the web) on the J2EE platform. We currently support both Orion 1.5.x and WebLogic 6.1 (we require EJB 2.0 compliance), meaning we use a single portal definition and can perform deployment to either platform in a few simple steps (local Orion deployment is fully automated). Since there are many differences in the most recent few releases of both Orion and WL, we could probably have endless discussions on the issues with porting from one to the other, but if you have more specific information (i.e. what versions of Orion the app is from and what version of WL is targeted), I could probably offer additional advice. As far as Security goes, we have written adaptors for managing users and groups in Orion and WL separately -- i.e. we wrote a custom UserManager for Orion and a custom Realm for WL that communicate with our EJB's. Also, if you want to write platform-neutral user management, check out the OSUser module of the OpenSymphony project, which is being developed specifically to address the different user manager implementations (and integrate them with external services such as LDAP or other legacy/proprietary security services) found in vendor J2EE implementations. Also, just FYI, we had many problems with Orion's CMP (wouldn't generate finder queries with multiple parameters) and WL's auto-table generation, so we ended up extending the EJBGEN package to generate both the orion-ejb-jar.xml and SQL scripts so we could create the tables for the CMP beans ourselves. Good luck and if you have questions, I'll be glad to offer additional advice. You might also try out the new forums at Atlassian (http://www.atlassian.com) or The ElephantWalker (http://www.elephantwalker.com) to get additional perspective on the subject. -Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Robert Krüger Sent: Tuesday, March 05, 2002 2:45 AM To: Orion-Interest Subject: pitfalls migrating an app from orion to wls Hi, just wanted to ask the list if anyone has migrated a compley app from orion to weblogic. we have a customer who wants us to port an app we developed for them from orion to weblogic (corporate policy). so far we have identified security (we have used orion security APIs) and cmp (we use EJB1.1 CMP and weblogic's capabilities in that area really suck) as two areas that need some work. any experiences anyone would like to share? thanks in advance robert p.s.: I sent this message yesterday but it didn't make it through.

RE: Like Statements in orion-ejb-jar.xml
I have used like statements successfully. Make sure of the following: 1) you have created an orion-ejb.jar.xml file in the META-INF directory of your name-ejb.jar file. This must contain the query. 2) you have deleted the existing orion-ejb.jar file from the deployment directory if you had already deployed your application. If you just overwrite/edit the orion-ejb-jar.xml in the deployment directory then this will not work. WARNING: When orion finally supports EJB-QL, the semantics of LIKE will change. EJB-QL does not allow like to be used with input parameters. Hence specifying an EJB-QL query of the type: "SELECT OBJECT(c) FROM Customer c WHERE c.name LIKE ?1" is illegal. You can only use constants or CMP fields in the like. Therefore if you base the running of your application on a LIKE comparison you will not be able to move to full EJB 2.0 compliance without some major reworks.

InitialContext Issue
Okay everyone I really need some help here We have an issue that I think I
have seen before, but I can't seem to find it in the newsgroup or archives
Currently we have a ColdFusion server running on our front end(try not to
laugh too hard) and Orion running in the back We created a LoginBean Class
which resides on the ColfSusion server and validates username and password
via a session bean on the orion server This works great until two people
try to login at the same time(ie the second tries to login before the
first completes the process) When this occurs, the first one to hit the
site gets validated and the second throws:
NamingException: unable to instantiate
comevermindserverApplicationClientInitialContextFactory
hen our LoginBean instantiates it calls a private method called
getJndiContext() which sets it's member variable jndiContext for use within
the class This is where the error is occuring
private void getJndiContext()
{
//get the context
if(jndiContext == null)
{
try
{
jndiContext = new InitialContext(); -! ERROR Occurs
Here !
userHome = (UserHome)
PortableRemoteObjectnarrow(jndiContextlookup(User),UserHomeclass);
profileHome = (ProfileSessionHome)
PortableRemoteObjectnarrow(jndiContextlookup(ProfileSession),ProfileSess
ionHomeclass);
}
catch(NamingException ne)
{
Logtxt(this, Naming Exception: + negetMessage(), LOGFILE);
neprintStackTrace();
}
}
}
I believe the rest of the class is unsbstantial when dealing with this
issue
So then I thought it could not create multiple instances of the same object
on the cold Fusion side So, I created a teb object that implemented
Runnable and created a New LoginBean for each instance thinking it would
work locally but not in Cold Fusion
here is the code for the test object:
import javarmiRemoteException;
/** User is an EJB containing user information(ie First Name, Last Name,
email, etc) */
import comweapiprofileUser;
public class RunnableLoginBean implements Runnable
{
LoginBean login;
StringBuffer sb;
public RunnableLoginBean()
{
this(null,null);
}
public RunnableLoginBean(String u, String p)
{
login = new LoginBean();
loginsetUserName(u);
loginsetPassword(p);
sb = new StringBuffer();
}
public RunnableLoginBean(String u, String p, StringBuffer sb)
{
thissb = sb;
login = new LoginBean();
loginsetUserName(u);
loginsetPassword(p);
}
public void run()
{
if(loginisUserValid())
{
try
{
sbappend(Hello : + logingetUser()getFirstName() +\n);
}
catch(RemoteException re)
{
sbappend(Error: + regetMessage());
reprintStackTrace();
}
}
else
{
sbappend(Login failed for : + logingetUserName() +\n);
}
}
public String test(int count)
{
for(int i=0; i count;i++)
{
Thread t1 = new Thread(new RunnableLoginBean(jhogan,password,
thissb));
t1start();
}
try
{
Threadsleep(5000); //make sure the threads are done before
printing
}
catch(Exception e)
{
sbappend(Error waiting: + egetMessage());
eprintStackTrace();
}
return thissbtoString();
}
public static void main(String[] args)
{
RunnableLoginBean lb = new RunnableLoginBean();
Systemoutprintln(lbtest(10));
}
}
This works fine on both my machine and the cold fusion server But if 2
users hit the same page at the same time(ie the second hits before the
first is finished), all ten(10) of the first connector's tests pass, and all
ten(10) of the second connector's tests throw the instantiation error I
seem to remember seeing this problem with JRUN before Since JRun and
ColdFusion are built by the same company I am assuming right now they may
use the same code for session/object storage and thus the problem may happen
on both platforms It's almost as if they have a Singleton Hashtable of
classes per object call and thus cannot instantiate more than one instance
of a class per application call
I am at a loss as to why this would happen Any ideas on why this is
happening and what we can do to fix it?
Thanx in advance
Greg

Check your config files in orion/config. It looks like a tag wasn't properly closed or is missing from server.xml application.xml, or global-web-application.xml. If you still have the originals or the tar ball, re xtract the files to another directory and compare them, or cross reference it with the Orion documentation for those files.

RE: pitfalls migrating an app from orion to wls
We recently completed a full migration, but in the other direction: WebLogic 6.0 to Orion 1.5.2. I think one of the major gotchas we ran across was the fact that WebLogic doesn't deal with .ear files very well, especially when trying to start the server with an existing ear. We were never able to get WebLogic to run pre-existing .ear as the default web application. Apart from that, we found that WebLogic's JNDI and JMS implementations were a lot more fleshed out, so expect improvements there. I don't know about the CMP aspect -- we use BMP. -Original Message- From: Robert Krüger [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 05, 2002 2:45 AM To: Orion-Interest Subject: pitfalls migrating an app from orion to wls Hi, just wanted to ask the list if anyone has migrated a compley app from orion to weblogic. we have a customer who wants us to port an app we developed for them from orion to weblogic (corporate policy). so far we have identified security (we have used orion security APIs) and cmp (we use EJB1.1 CMP and weblogic's capabilities in that area really suck) as two areas that need some work. any experiences anyone would like to share? thanks in advance robert p.s.: I sent this message yesterday but it didn't make it through.

Default autocommit is true or false?
Hi, list!
A strange problem.
I have a session bean that access a datasource. When a connection is
requested and method Connection.getAutoCommit() is called, I always obtain
true. The default autocommit isn't false?
Stranger! See this code:
try {
Connection con = getConnection(); //obtain connection in datasource
con.setAutoCommit(false);
stmt.executeUpdate(sql1);
stmt.executeUpdate(sql2);
} catch(Exception) {
sessionContext.setRollbackOnly();
}
When stmt.executeUpdate(sql) throws a SQLException, my session bean calls
setRollbackOnly and the transaction should rollback. In fact, I saw that
stmt.executeUpdate(sql1) didn't have effect in database just after this
method have execute. But after about 1 minute, I turn to database and I saw
that the effect of stmt.executeUpdate(sql1) was commited.
I repeat the experiment many times, and the same occurred after one minute.
It sounds like the container had setted the autocommit true after some
timeout. Does anyone knows what is happenning? The default autocommit isn't
false?

A Question about context-root directive
This is a resend, yesterdays version seems to have vanished... I'll confess, I'm a little confused. Documentation relating to J2EE states that the context-root directive in the application.xml or web.xml files should be used to provide a unique prefix for your web application to be access from: eg: web web-uriMyApp-web/web-uri context-rootweb1/context-root /web Will be accessed via: http://host:port/web1/myFile.jsp However, this setting seems to have no influence on orion, which prefers this sort of this to be set up in the web-site.xml file like: web-app application=MyApp name=MyApp-web root=/web1 / Am I missing something? Does orion ignore this context-root setting? I can't seem to find any document that discusses it. Any help appreciated.

Using Objects as a parameter with CMP finder methods
Is there a directive to add on the command line to make Orion log all generated SQL statements? Also, if I have a EJB CMP and I am writing a finder method and I want to pass a JavaBean as a parameter, how do I tell the finder which method or variable to use in the where clause? Is it possible to declare a java-Object as a finder parameter with CMP? For Example: where $name = $1getName() Thanks!
Deploying components common to EJB-tier and WEB-tier

Can I put them(the .jar file having the common components) in the same ear file as the .jar(for ejbs) and .war(for web components) files and be able to invoke them from both the web tier and ejb tier. Can you please tell me how the components can be invoked if I follow this approach.

More help for the newbie - javax.naming.NamingNotFoundException
I'm trying to learn ejb's using Orion's web
server. I'm currently running 1.5.4. I appreciate all the help I've
gotten so far.
Basically, I'm trying to get the CabinBean example
from O'Reilly publishings "Enterprise JavaBeans 2nd Edition" working. I
think I'm pretty close. I just need to understand a couple
things.
I'm basically referencing the enterprise beans from
an application outside the ejb container (a regualar class with a static void
main method). I've got all the required things put together. I have
the ejb-jar.xml in the META-INF of the cabin.jar. I have the
application.xml in the META-INF of the cabin.ear. I have an
application-client.xml in a META-INF of where my application is running.
It seems to be looking at the application xml like it should.
The problem is, when i do:
Context jndiContext = new
InitialContext();Object ref =
jndiContext.lookup("java:comp/env/ejb/CabinHome");
The client fails on the lookup statement. I
get the following error:
javax.naming.NamingNotFoundException: ejb/CabinHome
not found in Application Client
Now, when I look at my beans in the orionconsole,
it doesn't look like they are necessarily deployed under comp/env/ejb/. It
looks like it's listed under comp. Maybe this doesn't matter.
I've done some RMI programming in the past, and
understand some things about the naming lookup. For starters, where is it
specified where the beans actually get binded to?? For instance, with rmi,
if I had a bean called 'whatever', I could explicitly bind it to
"newbean/whatever", and then my lookup statement would be:
lookup("newbean/whatever"). Could someone explain this to me a
bit...
Mostly, I'm just trying to get my beans located
from my client program. Any insight on this would be greatly
appreciated.
Also, In my jndi.properties file, I'm using
ApplicatonClientInitialContextFactory. When I tried using
RMIInitialContextFactory, i got errors. Just curious as to what the
differences are, and what the proper factory is, and where it should be
used.
Thanks again for all of your help.
Joe
