DeadLock in UserTransaction
Hi I have discovered a deadlock problem with Orion 1.1.16 which I suspect is a bug: I do the following (in the servlet tier): 1. Begin a user transaction (getting the userTransaction from java:comp/UserTransaction). 2. Then create a new entity bean 3. Then execute a finder method which should return, among others, the newly created entity bean. 4. Commit the transaction The finder method locks in the database access. All bean methods are set to the "Required" transaction property. This means that they should participate in the user transaction (and not create their own). The database access isolation level is set to "committed". I am using SQL Server 7.0 and used the Enterprise Manager to investigate the problem. It appears that the create and finder methods are associated with different sessions in the database and therefore cause the lock. When I change the isolation level to "uncommitted" the deadlock disappears. This is as expected when the two methods run in different sessions. As far as I can see this should not happen, i.e. the container should use the same session (and transaction) for both methods. Please correct me if I am wrong but this is what I understand that the J2EE framework is suppose to do. Thanks Hans Barnard PS. I get the same behaviour with the stable version, 1.0.3b

Hi guys, Does anyone know of a decent site that details what should be described in the web.xml file, I can't find anything on Sun's site that is of any use, and how to go about creating a WAR file. cheers Bob
RE: Real Debuggin On Orion? How

JSP bug in state saving
I have written two JSP pages. The first does a JSP:include of the second in one of its table cells. Page 1 shows an ID with myBeanX.getID() Each of the pages uses MyBeanX with the same variable name and a scope of session. The included page, page 2, is actually a login page that does a myBeanX.setID = id for login from the page> and then calls the main page, page one, as its action. Page 2 also displays the current id with myBeanX.getID(). When page 1 is called, from page 2, it shows the previous ID while page 2, the included page, shows the "just set ID". Page 2 is the expected behavior. Page 1 is laggin behind. Comments, suggestions would be appreciated. Thank you.

RE: JSP bug in state saving
Using '%@ include...' is a static process. If you're using 'jsp:useBean...' in both that could be causing your problems. Also, why do you include page two into page one and then set the action to call page one again? Why not create another JSP page to process the login and then you can always do a redirect to whatever page you'd like. I'm not sure what your code looks like so it's just a guess. You're probably not using the 'jsp:usebean...' correctly in this situation. Code snippets would help.

RE: Real Debuggin On Orion? How
Steven, AFAIK, there does not exist the ability to do what you're looking for with any application server/IDE combo. I think you are going to be stuck running the entire application server in debug mode to step through the code. While I haven't tried it with Orion, I've debugged servlets in Resin using the 1.3 JDK, the JPDA (http://java.sun.com/products/jpda/) and Forte (http://www.sun.com/forte/). I don't see why this wouldn't work the same for Orion. To get around the issues with multiple developers, you might want to use CVS, a central "unit test" development server, and individual servers installed on each of the developers machines. Developers would check out the code to their local machine, test on their local copy of Orion (with the ability to run it in debugging mode without screwing everyone else up) and post their changes back to the unit test server to check for completeness. As a side note, CVS is a good thing if you're not using it already, especially when multiple developers get into the mix...

Multiple User Debugging Env? Doesnt' Exist?
Dear Darren: Thank for you reply. I'm coming to the same conclusion, and I would like to ask the Orion community at large, how does everyone do debugging? 1) Do you set up individual web servers for each developer, and thus use a normal debugging convention? 2) Is there any way to share a server, in particular, allow debugging by various developer of their actives, while allowing other user to work normally.

Adding a load-on-startup value to the web.xml file does not load the corresponding servlet until a URL from the enclosing web application is accessed.

Web-app reload still not working..
Hi, To whom may know what is going on, I am still having trouble getting the auto-code reload feature working. I posted before that the HtmlBean was giving a class cast exception, and Karl wrote back showing me some things that may be why. I implemented them and I am still having the problem. Karl mentioned that my bean is application scope so when Orion reloads the app, it can't cast the "old" version of HtmlBean to the new version reloaded. I put in the "implements Serializable" and added a private static final long serialVersionUID = 94989087234L (some number), and that still didn't fix it. The odd thing is, I am not working on the HtmlBean, I work on the AvailBean, which is a session scope bean. So, let me see if I got this straight. After testing something on the site, I can go to the code, change the source, and all I have to do is save it. Orion will recompile it and reload the whole code-base again. In the process Orion "saves" any http session objects (assuming they are all serializable objects) to disk, then reloads those objects into each session when reloading the web-app. This is to preserve the state of the HttpSesion across web app restarts, right? Is there anything I am missing here? Next, what exactly does this serialVersionUID do? Do I need to change it each time I change that class so upon reloading the changed bean, it knows its not the same one? Or do I just place the private static final long serialVersionUID = in each and every bean and/or object that can be put in the session, and thats it..leave it alone for good? How is it used by Orion (for that matter, any JVM/Servlet engine). I was told that it was not necessary in our code, but Karl mentioned it yesterday to me in the reply email, so I am a little confused about its use now. Lastly, is there any problem with application scoped beans and restarting web apps? Thanks again.
RE: Multiple User Debugging Env? Doesnt' Exist?
I would agree with Darren, each developer should have their own instance of Orion Server running on their own desktop. I'm assuming their machines are big enough and if you're using any of the full featured IDE's like VisualAge, VisualCafe, or JBuilder, than they probably can handle an instance of Orion. One of the kindest things Evermind is doing is allowing developers free use of their software for development purposes. Allaire just recently announced that same approach, why, because when you the developers use your software they're most likely to recommend it's use for production. I digress, sorry. Trying to share an instance of the web server for developing servlets is futile. I've been developing enterprise applications since 1983 on my PC, some were strictly PC apps others were mainframe Cobol, and most were distributed using C/C++ and now Java. I can't imagine sharing a development environment with other developers at least not until you get to integrated testing. You'll be amazed at how the time for development actually reduces and you can end up with more features and a more solid product. If it takes someone 5 days to do something in a shared environment that would take 2 in a dedicated one, by the time the 5th day rolls around they won't feel like spending more time testing and fine tuning their piece. I think the biggest challenge will be to ensure you have someone who really understands the Orion environment, otherwise, all is lost.There area lot of developers that don't want to know how to admin apiece of software like OrionServer, they just want to be users. If that's the case, then I would think about running multiple instances of Orion on the server for each developer or teams of developers assuming you have at least one person who now becomes a dedicated admin resource. my 2 cents.

Doesnt' Exist? Dear Darren: Thank for you reply. I'm coming to the same conclusion, and I would like to ask the Orion community at large, how does everyone do debugging? 1) Do you set up individual web servers for each developer, and thus use a normal debugging convention? 2) Is there any way to share a server, in particular, allow debugging by various developer of their actives, while allowing other user to work normally. I'm coming to believe this later paradigm (i.e. "2") is not ever done and is probably impractical. What environment do you have for debugging? Any comments welcomed.

How Steven, AFAIK, there does not exist the ability to do what you're looking for with any application server/IDE combo. I think you are going to be stuck running the entire application server in debug mode to step through the code. While I haven't tried it with Orion, I've debugged servlets in Resin using the 1.3 JDK, the JPDA (http://java.sun.com/products/jpda/) and Forte (http://www.sun.com/forte/). I don't see why this wouldn't work the same for Orion. To get around the issues with multiple developers, you might want to use CVS, a central "unit test" development server, and individual servers installed on each of the developers machines. Developers would check out the code to their local machine, test on their local copy of Orion (with the ability to run it in debugging mode without screwing everyone else up) and post their changes back to the unit test server to check for completeness. As a side note, CVS is a good thing if you're not using it already, especially when multiple developers get into the mix...

How Rob: Thanks for the reply. From your description it sounds like the operation and control of tomcat is taken over by the IDE. No one else would be able to use this server while you are in this debug mode. This same strategy should/must be doable for Orion or any other java based server. Perhaps my desire to have a server BOTH be running for some users, and also be able to
Error in ejbCreate() ...
My EJB (ServExecEJB) is a Stateless Session Bean. After the execution of ServExecEJB.ejbCreate() the following exception is thrown: com.evermind.server.rmi.OrionRemoteException: Error in ejbCreate(): Only beans with user-managed transactions can invoke getUserTransaction() at com.evermind.server.ejb.StatelessSessionEJBHome.getContextInstance(JAX) In my ejb deployment descriptor I specified transaction-typeBean/transaction-type, so I wonder why this exception occurs!

RE: Creation Of WAR Files?
I believe Orion has a GUI tool that creates a WAR for you, but that is beyond me. When I am developing, I don't WAR up the dir. I keep it expanded. You point to the WAR directory structure in default-web-site.xml in the /config folder. Just read up on that and you should be set to have a WAR file for development. Then you can JAR up the dir: jar cvf myfile.war root-dir That should jar up your entire www structure, including the WEB-INF folder which has /classes - the compiled code of your app /lib - the .jar and .zip libraries loaded for you by Orion (as per the servlet 2.2 spec) web.xml - the descriptor that explain to Orion how to run. Anything in /classes automatically becomes part of the classpath, that is part of the servlet 2.2 spec and should work on any servlet 2.2 container. Anything in the /lib folder should be loaded by the application server automatically and become part of the classpath as well. We put jdbc.zip (for Oracle 8i) there, along with activation.jar, mail.jar, jasp.jar, and other .jar files we need. At runtime they are automatically seen by your app (in the import statements of your classes). Nothing special to do. Orion has a very kewl feature that allows you, during development, to point to a "source" directory that matches the package structure output of your compiled classes. It then checks the source dir for changes (time-date) compared to the .class file it was compiled in to. If there is a change, it recompiles and reloads the web-app for you. This allows you not to have to shut down and restart orion every time you make a code change. Most app servers support this for classes in the /servlets dir, and generally that is javabeans and servlets. Orion (and Resin does this too) will reload the web app if any classes changed. The only downside is that it can take a few seconds for it to check the files. I believe its faster than restarting though. Dear Orion-Interest Group: Can I simply create a war file by: 1)Properly creating an WEB-INF directory. 2)Properly creating a WEB-INF/web.xml file. 3)Properly supplying WEB-INF/classes/*.class files. 4)Executing "jar cvf myNewWarFile.war WEB-INF" And I figure out all the more powerful graphics tools a bit later once I get the basic concepts down.

Fw: Creation Of WAR Files?
Kevin: Thanks for the reply. My interest in a WAR file is for placing an application in a production environment. It's very nice to simply ship it over, and keep track of it, as a single file. Thanks for you description below. It helps. Would/should JSP files also be located in the WEB-INF directory, or is it ok for them to be in a sibling directory that is also jar-ed up into the war file?
