ClassCastException confusion
Hi all
I have a class that is connecting to 2 beans. The one bean works while
the other gives me a
java.lang.ClassCastException: __Proxy4 at
com.test.manager.TestManager.main(TestManager.java:45)
exception. I have checked the listings. I could not find a similar case
where one bean worked and the other did not.
Object homeObject = initcontext.lookup("java:comp/env/TestManager");
TestManagerHome home = (TestManagerHome

TestManager locator =

Re: URGENT: talking with other app server?
Hi James.
I think , you can implement it.
Your servlet will just act as a client for other Application server.
For weblogic, you can download the evaluation version of Weblogic which is
free.
After deploying the bean to Weblogic you can include following lines
in the servlet.
Properties p = new Properties();
p.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialC
ontextFactory");
p.put(javax.naming.Context.PROVIDER_URL,"t3://:7001");
p.put(Context.SECURITY_PRINCIPAL,"");
p.put(Context.SECURITY_CREDENTIALS,"");
Context cx = new InitialContext(p);
Object objHome = cx.lookup(""); [jndi-name which is
specified in weblogic-ejb-jar.xml]
.etc.
While running Orion you have to also provide the classpath for Weblogic to
get Initial Context factory
which can be
\classes .

EJB SLSB Question
I can't find a _definite_ answer to my question. Hopefully, someone can give me some pointers. Is it legal, per EJB 1.1, for multiple client threads to access a SLSB? Here's why this is important for me. Apparently, there is no portable way for a SLSB to tell a client that it has timed out. Hence, if a client caches a SLSB, it is prone to some "random" error. So, I figured, I will write a "keep-alive" thread and wrap the SLSB in an application object as a delegate. And in the SLSB, I will implement a no-op - ping(). Now, there's the possibility, that the SLSB will be in a method call when the keep-alive thread decides to do a ping. DO I need to guard against that?

SUGGESTION: Display nested EJBExceptions ...
EJBException allows for the nesting of exceptions. Since EJBException indicates a system fault, it makes sense to display as much information as possible about it. When my application throws an EJBException, the browser displays a stack trace, but only for the EJBException. Would it not make sense to display the stack trace of the nested exception as well? It would be a simple matter of add the line: exception.getCausedByException().printStackTrace(); somewhere in some file, and it would help a lot.

Re: Problems with CMP PrimKey...
Hey, I'm not too hip on CMP for EJB 1.1, but for 2.0 the prim-key-class is given if you have a custom primary key class; the primkey-field is used if no custom primary key class is defined. Of course that can only work if there's a single field in the primary key. Gary On Wed, 8 Nov 2000, Sean P.

findByPrimaryKey problem, Oracle char(10) space padding
I'm having a problem with Orion's findByPrimaryKey() method when the column type is CHAR(10). The problem is Oracle pads out the column to fill in the extra spaces. For example, if you store "KEY" in a CHAR(10) field, Oracle saves it at "KEY ". This does not affect any queries run directly through JDBC or SQL-Plus (you can write "WHERE key = 'KEY' " without worrying about the spaces). Orion seems to have problems with it though. What I've found is Orion will only locate a record if I manually pad out the string when I'm creating my PK class. What exactly does Orion do for these finder methods? If it ran the query against the database, it should (theoretically) be handled by Oracle. Is there any way to see the SQL Orion sends to the database? I don't think it loads the table into memory beforehand, but is there some manipulation I can do to the EJB.java file (maybe in the ejbPostCreate()) to trim the values. I guess I don't totally understand how Orion compares the PrimaryKey class to the records in the database. Thanks in advance John

The J2EE RI´s DeployTool (which I usually use to package for major builds) has a set of tests designed for checking whether your .ear suits the specs.

Re: Transaction propagation question
Yes, J2EE doesn't support nested transactions. However, a similar effect can be achieved through the suspension of existing transactions. As far as I can tell, what's supposed to happen is Transaction 1 gets suspended while Transaction 2 starts, and commits or rollsback. Then Transaction 1 resumes and commits or rollsback. Because Transaction 2 will generally throw an exception when it rollsback, Transaction 1 will also generally rollback, which results in an approximation of a nested transaction. However, this is never explicitly stated in the spec, so it would behoove you to make sure to rollback transactions yourself in your code when you must be SURE they get rolled back. Since you (Aziz) defined the SQL Delete statement, it doesn't necessarity have to be rolled back if some other transaction rolled back. I say "doesn't necessarily" because it really depends on the order and way in which you are doing things. However, you might want to try adding the following code to your catch clause in the HelloBean or HashCodeBean class. sessionContext.setRollbackOnly(); // sessionContext is the SessionContext object that is passed to the Bean in setSessionContext and stored as a member variable as per the EJB 1.1 spec Hope this helps. Anyway, transactions in Orion are still sketchy at best... -Dan "Juan Lorandi (Chile)" wrote: I think it defaults to NotSupported; also have in mind that J2EE only allows flat transactions, so, if you a a secuence Required ---> Requires New T1 T2 it will perform 2 transactions, not connected between each other, that is, if T2 fails, T1 doesn't fail autoamtically. -Original Message- From: Aziz Sharif [mailto:[EMAIL PROTECTED]] Sent: Viernes, 03 de Noviembre de 2000 18:11 To: Orion-Interest Subject: Transaction propagation question I have a question regarding transaction propagation. I took the orion primer example and modified it so that the servlet calls Hello and then the Hello Bean calls A HashCoder bean. Both Hello and HashCoder beans are stateless session beans and perform SQL. The Hello does a delete and the HashCoder an incorrect select (causing a SQLException). I was expection these two operations to happen in the same transaction, so that the SQLException would cause the delete to automatically rollback since for both these beans I specified Container managed transaction. But it did actually delete the row. So it seems they two methods were running in different transactions. The only thing I did not do is to specify the tranaction attribute to the bean's methods to be Required or anything else. I don't know what it defaults to in orion. I am using DB2 v. 6.1 as the Database, the in both beans I acquire the connection through JNDI DataSource. I configured the data-sources.xml for DB2 as follows: class="com.evermind.sql.DriverManagerDataSource" name="Db2" location="jdbc/Db2CoreDS" xa-location="jdbc/xa/Db2XADS" ejb-location="jdbc/Db2DS" connection-driver="COM.ibm.db2.jdbc.app.DB2Driver" username="db2admin" password="db2admin" url="JDBC:DB2:EB2" inactivity-timeout="30" /> I am attaching the zip file containing the modified orion primer example, that can be built simply by tying ant. I would like to know how to get something like this where multiple session beans participate in a single transaction such that if any one throws an SQLException the transaction is rolled back by the container.

EJB 1.1 findByPrimaryKey in orion 1.4.3 broken ?
I'm developing an EJB app for a while now on orion. The last version I had installed was 1.4.0. Most of my app was already working like a beauty. Today I auto updated to 1.4.3 and it seems that findByPrimaryKey where the primary key is a comppound primary key, got broken. I did some test and all my calls to findByPrimaryKey(java,lang.String) seemed to work. However all calls to findByPrimaryKey(new PrimaryKeyClass)) throw a finder exception. I reverted back to 1.3.8 which is running on an other machine, copying orion.jar to my dev box and all worked perfectly again. Has anyone seen this??? It would be very nice if autoupdate.jar would create a backup for the updated files for example in the form of: orion/backup/xxx.jar.version.no this would enable us to revert back to the last stable version some more graciously. sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==
RE: There has GOTTA be a BETTER way !!!!
My take on EJB is that while they seem to be more work (now that I have done it a couple of times..but I am far from pro caliber here), they are actually a bit less work if you are using CMP, instead of BMP. However, I have heard that EJB 2.0 CMP is more complicated, and it along the same amount of work. What scares the hell out of me is all the descriptor xml files. When you make a change in code..you can build it and see problems if they exist. When editing XML files, its not immediately apparent if there is a problem in a CMP mapping, a reference tag, etc. Only when you try to run the app do you see the problem. It would be nice if there was some auto-mated tool that would look at the source (or compiled classes) and sort of "compile" an xml file and flag if errors exist. I don't see that happening though..probably too much work to get that to work right. > -Original Message- > From: Keith Kwiatek [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, November 07, 2000 11:48 AM > To: Orion-Interest > Cc: [EMAIL PROTECTED] > Subject: Re: There has GOTTA be a BETTER way > > > Does anyone know if jdeveloper (which is based on Jbuilder) > has the same > functionality? > > Keith > > - Original Message - > From: Cory Adams <[EMAIL PROTECTED]> > To: Orion-Interest <[EMAIL PROTECTED]> > Sent: Tuesday, November 07, 2000 9:34 AM > Subject: Re: There has GOTTA be a BETTER way > > > > JBuilder 4 Enterprise allows you do build Entity CMP beans > this way.

RE: BMP vs CMP with Orion
This can be complex as you have to indicate which relation to use. Does it
only work for simple cases?
For instance below you have three relations to the field person.name
1. one direct
2. via father
3. via mother
Table person(name, father_fk, mother_fk);
Translating to:
class person {
.
.
.
private String name
private father person
private mother person
}

I have had no problem with shutting down Orion 1.3.8 nor Orion 1.4.3 under Solaris 8 with JDK 1.3.0. As a nonroot id "orion" (I have changed the default port in config/default-web-site.xml to be above 1024) I set the following: setenv JAVA_HOME /usr/j2se setenv LD_LIBRARY_PATH /usr/j2se/jre/lib/sparc/server:/usr/j2se/jre/lib/sparc and use the following command to start Orion (while logged in as "orion" from Orion's install directory (referred to as [ORION_HOME])): /usr/j2se/bin/java -server -Xms8m -Xmx48m -jar orion.jar & I use the following command to stop Orion (while logged in as "orion" from [ORION_HOME]): /usr/j2se/bin/java -jar admin.jar ormi://localhost admin mypassword -shutdown While setting up Orion, I copied the file /usr/j2se/lib/tools.jar to [ORION_HOME]. I also reset the default password with the command (use chmod to allow only "orion" to read the clear text password file): /usr/j2se/bin/java -jar orion.jar -install chmod 600 iconfig/principals.xml Note: JDK 1.2.2_06 runs Orion faster than 1.3.0 under Solaris 8.

RE: What's new? - Where is 1.4.2??
Actually, no, you can't always do this, for two reasons. First, on a Unix system, we the orion user the permission to write to itself. This is a basic security procedure. As a xonsequence, autoupdate won't work. Second, although I may be able to do this, I may not want to. There is risk in grabbing the newest experimental server and I'm not always willing to accept that risk. If things are working for me and I have a tight deadline, I prefer not to update unless there is a fix or an enhansement I need. Therefore, I prefer to check the changes.txt file first.

Bug with Java Code and HTML Comments?
All, Something else I just noticed... Java code (scriptlets) within HTML comments is ignored... while JSP Expressions are evaluated... does this not make sense? Or is it just me? Here is a simple example : <% int val = 1; %> The value is: <%=val%> The value is: <%=val%> You would think that within the HTML comment you would see that the value is 1.. and you DO =)... but you would also think that the val would then be changed to 5... but it doesn't.. it still equals 1 when we print it out at the end. Here is the Output HTML The value is: 1 The value is: 1 The java scriptlet has not been evaluated.. this works with other app servers.. an Orion bug or feature? To me Java code should only be ignored it is within JAVA COMMENTS... not HTML COMMENTS. I run into this all the time because I have comments around my JavaScript code... and the JavaScript code I am generating is fairly dynamic. Dylan Parker
autoencode breaks my HTML?
Hello, all. Has anyone else has strange occurences where autoencoding-urls breaks their HTML? I have one instance where adding a space makes it work.. without it results in a badly broken anchor tag. Example: This doesn't work : <%="SOME_TEXT"%> OUTPUTS: This works : <%="SOME_TEXT"%> OUTPUTS: SOME_TEXT The difference is the space after the '>' of the A tag. I turn autoencode-urls off (both absolute and relative) and the problem disappears. It seems it has to do with when you have scriptlet or an expression directly following the closing bracket of an anchor tag... A problem with the auto-encoding code? Can anyone else verify this? I'm using Orion 1.3.8 under Win2k with JDK1.2.2 if it helps. Thanks, Dylan Parker

Non-serializable object turns into null
Hello I had forgotten to mark some helper classes, which are sent from an EJB to a JSP, as implementing Serializable. I didn't notice any side-effects when I was running Orion 1.3.something (the JSP and the EJB containers being in the same JVM). When I upgraded to 1.4.3 this morning, everything broke ;) Instead of throwing a "can't serialize" type exception, non-serializable objects come back to the client as null with no warning. Is that correct behaviour? Makes it a bit tricky to debug ;) In order to get an exception to happen (so I could figure out which object was causing the problem by reading the message) I had to write the object to an ObjectOutputStream before returning it.

ejb 2.0 relations in orion 1.4.3 broken ?
The current ATM example uses EJB 2.0 definitions of ont-to-many relationships (account_owner -> account) . When I deployed it on orion 1.4.3 it workes quite well until I added some accounts. After shutting down orion and re-login all accounts are lost.

Auto-started clients, JMS and transactions
Hello, I just installed 1.4.3. The good news is that my previous problems with JMS subscribers, when running as auto-started clients, not getting messages delivered is resolved. However, it appears that the auto-started client's message handler (onMessage()) is invoked within the transaction context of the publishing EJB call. Is this expected behavior? I would think that the message handlers would be invoked outside of the transaction. If this is expected behavior, how can I design around it? Here's a stacktrace that shows the calls (the non-reentrant exception, I believe, is an artifact of the problem) The flow is that the EntityBean (datawatchItemBean), in its postCreate publishes a message and an auto-started client (DataWatchEngine) subscribes to these messages. I'm not an expert on JMS (barely getting started with messaging) and would appreciate all help. Thanks, Vidur com.evermind.server.rmi.OrionRemoteException: Recursive call to non-reentrant be an at com.evermind.server.ejb.AbstractEJBObject.startCall(JAX) at DataWatchItem_EntityBeanWrapper18.getDataWatchEntry(DataWatchItem_Ent ityBeanWrapper18.java:1014) at com.epistemic.km.server.DataWatchEngine$NotificationHandler.onNotify( DataWatchEngine.java:195) at com.epistemic.km.server.ServerNotificationListener$MessageListenerImp l.onMessage(ServerNotificationListener.java:30) at com.evermind.server.jms.ct.lr(JAX) at com.evermind.server.jms.cu.lr(JAX) at com.evermind.server.jms.EvermindTopicConnection.l8(JAX) at com.evermind.server.jms.JMSServer.lq(JAX) at com.evermind.server.jms.ch.k9(JAX) at com.evermind.server.jms.cu.l5(JAX) at com.evermind.server.jms.cv.publish(JAX) at com.evermind.server.jms.cv.publish(JAX) at com.epistemic.km.server.Notifier.publish(Notifier.java:87) at com.epistemic.km.server.Notifier.notifyCreate(Notifier.java:101) at com.epistemic.km.server.DataWatchItemBean.ejbPostCreate(DataWatchItem Bean.java:69) at DataWatchItemHome_EntityHomeWrapper51.create(DataWatchItemHome_Entity HomeWrapper51.java:506) at com.epistemic.km.server.DataWatchServiceBean.addWatch(DataWatchServic eBean.java:110) at DataWatchService_StatelessSessionBeanWrapper8.addWatch(DataWatchServi ce_StatelessSessionBeanWrapper8.java:138) at java.lang.reflect.Method.invoke(Native Method) at com.evermind.server.rmi.bf.do(JAX) at com.evermind.util.f.run(JAX) -- Vidur Dhanda Active Solutions tel: 617/566-1252 [EMAIL PROTECTED] www.active-solutions-inc.com
Shutting down orion
Although I can shutdown orion using the admin.jar with a 1.2 JVM, I've found that I cannot with a 1.3 JVM. The server ceases to accept connections, but its process does not go away. (Running on Redhat/Debian Linux) Anyone else noticed this?
startup & shutdown classes
In weblogic's properties file, I can register classes that are laoded into WL server and execute each time WL is tarted or shut down. Can I do something similar in Orion ?

DB-connection timeout
I know that others have had performance problems with timeouts when running out of DB-connections. Has anybody figured out where this value is set? Some have stated that the problem disappears when running Orion with enough memory, but we see no difference even with large amounts of mem. Is there some other magic lever to pull? /Marcus -- Marcus Ahnve email: [EMAIL PROTECTED] Lecando AB Office: +46-(0)8-634 94 18 Sweden Mobile: +46-(0)70-462 19 18 www.lecando.comICQ#: 4564879

Just without a lot of the wizards, the jbcl (various borland db enabled tools, layout managers, etc) classes and things like group tools, or source code. With some effort you can configure the foundation to do a lot of the things enterprise does. For example, you can get the j2ee stuff from sun to include as a library (so jbuilder will browse the source automatically) and use the sun deployment tool from a menu in jbuilder. So you can see if you like the environment and then decide about the enterprise version. Which has all of the bells and whistles turned on. Of couse you don't actually need any of this stuff but it's all nice to have. dave

There is a one to one mapping between the home interface, the remote interface and the bean implementation. EJB 1.1 (or 2.0 AFAIK for that reason) does not allow you to have several implementations answering to one set of interfaces. You could possibly solve it halfway by declaring a common super interface which the two remote ones extend, but you will still need two set of interfaces. /Marcus -- Marcus Ahnve email: [EMAIL PROTECTED] Lecando AB Office: +46-(0)8-634 94 18 Sweden Mobile: +46-(0)70-462 19 18 www.lecando.comICQ#: 4564879
validateXML
Last week I discovered the validateXML command line option and thought is was great. The more I use it, though, I realize it's near useless. Here is why. The two validating parser's that ship with Orion (Apache's xerces and Sun's jaxp) validate the DTD as well as the xml file. The problem is, it seems to find problems with the dtd's (some of which are sun dtds and some of which are Orion dtds). Why are the dtds invalid? I have no idea. What's more, these dtds are inside the orion.jar file. So fixing them is a pain. Please someone comment if they have found otherwise. Or if you have a solution. Thanks.

RE: HIGH PRIORITY:Contact Information??????
As the movie says, "just show them the money". :-) We just went ahead and bought it, and the license showed up within 24 hours. The procedure is so simple that maybe folks are still expecting an elaborate process akin to purchasing a $50,000 or $100,000 software application. Orion is only $1500, after all, and for those sums I expect no process other than payment. Putting it another way, if you want to license the server, the link is there on the main website.

Re: Where is Orion's copy of ejb-jar dtd?
<> Thanks Rober. I don't think that's it though. I got the same error with the Orion provided "news" ejb. I think It's trying to validate against the 2.0 DTD. Dave Ford Smart Soft - The Java Training Company http://www.SmartSoftTraining.com
ejb-jar.xml DTD: 2.0 or 1.1
I have found that Orion is validating my ejb-jar.xml against the wrong DTD. My ejb-jar.xml has a 1.1. DOCTYPE specified but it's STILL being validated against the ejb 2.0 doc type. How do I turn this behavior off? Thanks, Dave Ford Smart Soft - The Java Training Company http://www.SmartSoftTraining.com
Re: Where is Orion's copy of ejb-jar dtd?
I've just moved a bit closer to a solution. I found in the docs that I can specify (as a command line argumnet "which" xml parser to use: java -Dxml.parser=xerces -jar orion.jar -validateXML or java -Dxml.parser=javax.xml -jar orion.jar -validateXML Upon using the xerces parser, I got a new error message: Error loading package at file:/C:/@web/ClassNotes/EjbJmsJndi/@StudentEjbApp/, Error parsing META-INF /ejb-jar.xml in C:\@web\ClassNotes\EjbJmsJndi\@StudentEjbApp: Fatal error at line 912 offset 1: A ') ' is required in the declaration of element type "role-source". Warning at line 1: Valid documents must have a http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd"> So my new question is, how do I tell Orion to use the 1.1 DTD instead of 2.0 DTD to validate my ejb-jar.xml?

Re: ejb-link
Hi again! I want to look at them as two separate beans, only with the same interfaces. They are both declared and have different names, the only thing they have in common is the remote and home interfaces. I really would like to be able to access them both. But when I do the references only one of them works.

Personally I think > it's a bug in Orion, but I hope to be proven wrong :) You're in luck, because this is a EJB feature. ejb-jar.xml is defined by JavaSoft and is the same everywhere you go in EJB country. You simply can not do this. When referencing one bean from another you are essentially being just another client of that bean. And since clients can not, and should not, know anything about the current implementation, you are not able to declare which implementation bean to use. /Marcus -- Marcus Ahnve email: [EMAIL PROTECTED] Lecando AB Office: +46-(0)8-634 94 18 Sweden Mobile: +46-(0)70-462 19 18 www.lecando.comICQ#: 4564879
ClassCastException
Hi ppl,
I have a stateless session bean ChannelManager. I wrote a test class
ChannelManagerTest to test the bean.
Line 12: ChannelManager channelManager = (ChannelManager)
JNDIHelper.getHome("akela.pesos.content.news.ChannelManager");
( JNDIHelper is tested and is working just fine )
I get the following exception when I execute it:
java akela.pesos.client.ChannelManagerTest
Exception in thread "main" java.lang.ClassCastException: __Proxy4
at
akela.pesos.client.ChannelManagerTest.main(ChannelManagerTest.java:12)
jndi.properties is:

Any idea ?

IMHO it's all a matter of architecture, which in turn is very dependent on the preconditions of the project. If you are running a green field development process, I would definitely go for designing EJB's up front and create the DB according to them. Which is by the way how we do it here at Lecando. On the other hand, if you have to adapt to an existing DB or have development process that is DB-centric I guess you just have to do with whatever the DB guys throw at you.

RE: Placement of jars for JSP
Title: RE: Placement of jars for JSP Well, if you point out your tld from your web.xml file like: database-taglib /WEB-INF/database.tld you can have your taglib.tld in your WEB-INF directory. You can have the classes used by the taglib in your /WEB-INF/classes/ if you want.
