javax.jms.MessageFormatException when ObjectMessage.getObject()
Hi,
I'm sending message via topic:
ObjectMessage
message = session.createObjectMessage(new
Event());
session.createPublisher(topic).publish(message, deliveryMode, priority,
expiration);
When I catch the message in my MDB,I get
exception in getObject():
public void
onMessage(Message msg)
{1.Thread.currentThread().getContextClassLoader().loadClass("com.cleverlance.cmds.comm.Event");2.((ObjectMessage)msg).getObject();Class
Event is in classpath and is visible for classloader (line 1 is ok). When
running line 2, I get javax.jms.MessageFormatException:
com.cleverlance.cmds.comm.Event
Class Event is very simple:
package
com.cleverlance.cmds.comm;
public class Event
implements java.io.Serializable {
public
Event();
}
Do you know what's wrong?
Thanks.
Re: BigDecimal problem...
Hi Nicolas,
seems like you caught a bug in the Postgresql's JDBC driver.
I had similar problem using the driver from Postgresql 7.1.3,
you can either upgrage your driver to version 7.2 or
apply the following patch and rebuild it:

Thanks, but I have already mapped BigDecimal type in this database schema.
As I'm using Postgres dbms for development I have mapped it as follows but
without any success:
type-mapping type=java.math.BigDecimal name=decimal /
As far as the pk type is concerned it is not up to me, being an Orion user
basically I've always used long types. Still my task is to port this
application from Weblogic to Orion - J2EE protability ;).
Anyways, thanks for helping me out.

This could be your database-scheme. I notice that most of the database
schemas that come with Orion (look at the config/database-schemas) do not
include a field for java.math.BigDecimal. However, the SapDB.xml schema
does. Copy this bit into your database schema, and this will probably fix
your problem:
type-mapping type=java.math.BigDecimal name=fixed(15,15) /
Why aren't you using Long as the pk? Many who use orion use Long's. This
could be why you found this problem, because you were the first to use a
BigDecimal as a pk.
If you are new to Orion, come join us at www.elephantwalker.com. We have the

Subject: BigDecimal problem...
Hi,
I'm having a really annoying problem with Orion. I'm importing an
application from Weblogic to Orion. It consists of basic CMP EntityBeans so
that I can test whether I can port a much bigger application. Anyways, those
Beans use BigDecimal as Primary keys.
In the design of this application, some of those beans have a parenthood
relationship as well as references to other beans. As the application should
allow null parenthood for instance, the beans should store null value in the
associated DB field.
This being said, this test framework works fine with weblogic. As far as
Orion is concerned, I get NullPointerExceptions when creating the beans,
which by default have null references to other beans. As I found it weird I
messed up with the automatically-generated classes -e.g.
PersonBeanHome_EntityHomeWrapper14.java - and I found out that when a bean
generates PreparedStatements and instanciates them, it checks whether String
or Date fields are null and if so call the setNull(...) method, but does not
for BigDecimal fields leading to the NullPointerException.
Well, d'you have any idea how to walk round this?
Thanks,
Nicolas
Re: File Upload from an Application
you need to use 1. type="file" in the form within the browser. 2. get a ServletInputStream (?) from the request object in Orion and parse out the byte stream. do a search for ServletInputStream in google or something and you should find some examples. afaik, there is no simple method to call to extract an uploaded file from a request but parsing out the ServletInputStream data is not that hard. greg. - Original Message - From: Michael Maurer To: Orion-Interest Sent: Monday, March 04, 2002 5:38 PM Subject: File Upload from an Application Hi I am trying to upload a file from an application to the orion server, but could not find the right solution so far.

Re: javax.jms.MessageFormatException when ObjectMessage.getObject()
I solved this problem by putting transmitting class
(Event) into orion's lib directory.It's not clear solution, but it
works.
I realized that bean's classloader knows the where
the class Event is, but message's classloader knows only path to orion's
lib.

RE: File Upload from an Application
Also, You will need to use a POST form, with the parameter: enctype=multipart/form-data. Don't forget to handle the parameters as well as the files, they're no longer visible with req.getParameter() when you use this. There is a few MultipartParsers out there, including an Orion version. I would recommend wrapping these in an interface, so you can easily swap them. Not that I don't trust them or anything, but its code I have no control over.

RE: How can I perform an action when web user is first logged on?
If you want to use form-based authentication, the only 'legal' way that I can think of is to write a sessionfilter that checks when a principal exists for the first time during a session. Otherwise you'd have to do your own authentication, calling RoleManager.login() and if it succeeds write a record to the database with the current date. (Of course this could be within a filter, too) This would be much easier if either login() or authenticate() would be handled by the UserManager (which is user configurable), but alas that is not so ... A real hack would be to have two forms on the login page, the first one being submitted on buttonpress to itself, where it handles the creation of the login record, and then when resent automatically submitting the loginform (which must have been filled out previously) to j_security_check by script ... drawbacks: the user may notice the screen reloading, and I noticed most people here try to avoid html client side programming like the pestilence:) cheers --peter -Original Message- From: Alex Paransky [mailto:[EMAIL PROTECTED]] Sent: Sunday, March 03, 2002 9:30 AM To: Orion-Interest Subject: How can I perform an action when web user is first logged on?

Re: How can I perform an action when web user is first logged on?
This would work great except that you cannot 'force' a container to bring up the login page (portably). UserManager doesn't help you because it too is an Orion specific API (just like RoleManager) About the only way to do portable user management/authentication/authorisation is with an open source project called OSUser (part of OpenSymphony which I participate in). See http://www.opensymphony.com/osuser for details. I currently have an application porting well (single EAR) between JBoss and Orion, and Weblogic/Pramati/JRun support are almost done. It also supports Resin (if you just want WARs).
