Subject: OFFTOPIC: Making a page expired
I am trying to get the browser to display the "this page has expired"
message when the user hits the Back button on the browser.
We have the luxury? of only needing to support IE5.5. No matter what meta

This is especially important in the situation where the user's session has

Any ideas?

byte array OR mapping...
Hello,
I have an Entity Bean :
public class ResultBean implements EntityBean {
[...]
public String id;
[...]
public byte[][] graphResult;
}
The graphResult field is an array of byte arrays. I want it to be stored as
a list of BLOBs. Here is my mapping for this field (orion-ejb-jar.xml) :
cmp-field-mapping name="graphResult"
list-mapping table="graphics"
value-mapping type="[B"
cmp-field-mapping
fields /
/cmp-field-mapping
/value-mapping
/list-mapping
/cmp-field-mapping
The '[B' is the String returned when I do byte[].getClass().toString()
But when I deploy :
Error compiling file:/C:/orion/applications/rapids/rapids-ejb-result.jar:
Dependent OR class [B cannot be abstract unless the ejb-jar.xml has a
dependent tag for it
What's wrong ??? Can someone helps me ??
Thanks

RE: Anyone using Orion in production? [long]
If you think about it, Sun released their source code for JSP and servlets to Apache. IBM and Sun have people working and developing Tomcat, in addition to the Apache volunteers. Yet there are many commercial products implementing JSP and servlets (Jrun, Servlet Exec, Etc.). Similarly, if you have open source servers like jBoss, joNas, openEJB, etc., they will coexist among commercial versions. Yet both commercial and open source versions will stir companies to implement Sun J2EE solutions over Microsoft MTS. I think Orion is a great product, but it will take both open source and commercial products to give J2EE solutions popularity and keep Microsoft MTS at bay. -Original Message- From: Kevin Duffey [mailto:[EMAIL PROTECTED]] Sent: Friday, November 24, 2000 1:43 PM To: Orion-Interest Subject: RE: Anyone using Orion in production?

Re: Can't find DataSource at java:comp/env/jdbc/NameOfDataSourceDS..??
If you open a console (java -jar orionconsole.jar ) you will see that your
jdbc connections are in fact can be found in JNDI at jdbc/myEJBDS and not
java:comp/env/jdbc/myEJBDS.
You are getting casting exception because in your datasources.xml you
defined DataSource as com.evermind.sql.ConnectionDataSource and not
interbase.interclient.DataSource. These two classes are siblings. Java
doesn't support casting between siblings.
This code should be better as it will work with any databases and any
datasource classes.

Hi all,
Strange things abrew. I have my Interbase datasource set up as list below.

I
have to be database specific or vendor specific at any point, and why is
it
not finding it in java:comp/env?

RE: byte array OR mapping...
The '[B' is the String returned when I do byte[].getClass().toString() I don't think you want to do that. Firstly, a byte is not a class. byte is a primitive like int, float, char, etc. which are not classes in Java (maybe you are a Smalltalk programmer?). Second, getClass().toString() isn't correct; you should have used getClass().getName() to get the name of a class. A Class is an object, and toString() usually returns a serialized version of that object (usually, not always). You should probably take your byte[] and place it in a class that implements java.io.Serializable. Most of the database mappings support placing that into a blob: type-mapping="java.io.Serializable" name="blob" -tim

RE: Problems with the Orion CMP primer example.
Sorry for the delay (Thursday was a holiday here (unless you're a turkeyg), and I took Friday off...). However, I see from the mail list that you've fixed the problem. The file $ORION_DIR/config/data-sources.xml contains the configuration for your jdbc connection(s) - part of the data-source element is the jdbc URL, which (at least for hypersonic) includes the path to the database files. For example, from my development system: data-source --- (many attributes skipped...) connection-driver="org.hsql.jdbcDriver" url="jdbc:HypersonicSQL:../oriondb/SBDdb" / In our case the database directory is moved outside the $ORION_DIR tree - mostly because it made it easier to update Orion in the pre-autoupdate days, and uses several files named SDBdb and different extensions. The given path is relative to $ORION_DIR, and the format is described at http://www.hypersonicsql.com/ (click on Operating Modes) under Standalone mode.

Used Instances
In Orion console, what does 'Used Instances' denote? I'm doing batch updates to a database (about 20 daily) and about three quarters on the way, Orion console shows some 59000 used instances of my entity bean somewhere after that, my application crashes with a DeadlockException and shows that the nested exception is an OutOfMemoryException. I'm at a loss here, does Orion actually keep these 59000 entity beans in memory ?? Shouldn't these be pooled ?? (Pooled instances shows 0!!). I'm currently testing the application and would like to know if there's any way to have these beans pooled. The app that does the batch updates is a simple class, it reads the lines in a file and then calls a session bean (stateless) through either of two methods (update or remove) update checks for excistence of the entity, if exists, it sets some values, when a FinderException gets thrown, it calls ejb.create(). remove finds the bean and calls ejb.remove(). I read in the specs(9.4.1): The container can choose to passivate the instance (...) Th container invokes the ejbPassivate() method when the container wants to disassociate the instance form the entity object without removing the entity object. I've been printing some output to stdout telling me when a bean is activated and when it's passivated but sofar as I can see, ejbPassivate() is never called.

You can however in orion-ejb.xml set exclusive-write-access="false" in entity-deployment. Sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] == _ Do You Yahoo!?

Re: Used Instances
Could it be that all of your beans are still in a Tx? I do not believe the beans will be passivated when they are still involved in a Tx. Or are you invoking a new Tx for each line in your file. tim In Orion console, what does 'Used Instances' denote? I'm doing batch updates to a database (about 20 daily) and about three quarters on the way, Orion console shows some 59000 used instances of my entity bean somewhere after that, my application crashes with a DeadlockException and shows that the nested exception is an OutOfMemoryException. I'm at a loss here, does Orion actually keep these 59000 entity beans in memory ?? Shouldn't these be pooled ?? (Pooled instances shows 0!!). I'm currently testing the application and would like to know if there's any way to have these beans pooled. The app that does the batch updates is a simple class, it reads the lines in a file and then calls a session bean (stateless) through either of two methods (update or remove) update checks for excistence of the entity, if exists, it sets some values, when a FinderException gets thrown, it calls ejb.create(). remove finds the bean and calls ejb.remove(). I read in the specs(9.4.1): The container can choose to passivate the instance (...) Th container invokes the ejbPassivate() method when the container wants to disassociate the instance form the entity object without removing the entity object. I've been printing some output to stdout telling me when a bean is activated and when it's passivated but sofar as I can see, ejbPassivate() is never called. Is this some bug in Orion or am I getting mad??? I'm using 1.3.8 sven
Turbine with Orion?
I'm getting ready to set this up (Turbine and Velocity) with Orion. Before I pull my hair out figuring it out, I wanted to see if anyone has already documented this? Thanks.

On the same topic..is there any way to FORCE the browser to always go to the

but whenever a user hits the BACK button they always see the "this page has
expired". Isn't there any way at all to force the browser to go to the
server..in which case I have code in place that would redirect them to a
specific page that is more user friendly and looks like our site..rather
than the MSIE page?

I am trying to get the browser to display the "this page has expired"

We have the luxury? of only needing to support IE5.5. No matter
what meta
tags i use I cant seem to get the browser to display the standard
"this page
has expired" message.
This is especially important in the situation where the user's
session has
expired and the user then uses the back button and tries to click on a
hyperlink on the old page.
Any ideas?
RE: OFFTOPIC: Making a page expired
Jeroen - you are a star
What this header basically does is re-request the URL when the user hits the
back/forward buttons.
That also fixed a couple of other 'what happens if the hit the back/forward
button' issues i was having.
One huge advantage about the 'CACHE-CONTROL' tag is that the browser can
still use the cache to get images, javascript includes, behaviours etc. Best
of both worlds really.

Using examples from Sun for J2EE reference implementation with Orion
I decided to try out the examples at http://developer.java.sun.com/developer/onlineTraining/J2EE/Intro/index.html#contents with Orion. These examples are from Sun and are for the reference implementation of J2EE. I am able to get the samples to work on the reference implementation, but not for Orion. :o( Has anyone else try to "port" these samples to Orion? It should be really easy. Orion is compliant. What is the easiest way to deploy the ear files from these samples? (This is good because the ear files are valid and tested.) I did this because I've been having troubles. I went through the Orion primer. No Problem. I tried to port some custom beans to Orion. Problems! I figured there was something I did wrong in the web.xml file, server.xml or something so I would try some really well formed beans and servlets. If I can't get the beans from the reference implementation running, then So now I figure if someone has already got the samples for the reference implementation to run in Orion, then I am all set. (If they tell me what they did to get them running.) Conversely, I could tell you what I did that did not work. Challenge: I think one of the Orion advocates can get one of these examples to work in no time flat. If not, I will keep plugging along. __ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores.

WRT "aside its always useful to describe WHAT error you are getting /aside" Good point. I had a brain brownout. The only error I got was from the browser. The error was HTTP 500 - Internal server error when I posted to form action="/employee-app/com.objectgeneration.sample.EmployeeForm" method="post" and the error was also HTTP 500 when I posted to form action="/employee-app" method="post" I tried your first suggestion, i.e., I posted with form action="/employee-app/servlet/com.objectgeneration.sample.EmployeeForm" method="post" with the existing setup and I get You guessed it HTTP 500... That is okay at least I got the Post format correct. So in additon to the problem you helped me with... I have yet another problemwhat a mess I am. On to your second suggestion. I see that you changed the name of the servlet, but I am not sure what else you did nor am I sure what is different other than the shorter name, i.e., I already had a servlet mapping. But just in case I am an idiot (which I wont rule out). I followed what you wrote to a tee. [opps I just saw that i forgot to include my servlet mapping sorry another brain brownout.] BTW I also tried someone elses idea of what the servlet mapping should look like, and it did not seem to work. I think I don't have the post correct for a corresponding servlet mapping. What would be the post for that mapping? i.e., what would the post look like for the mapping that you suggested?? I think it would look like form action="/employee-app" method="post" or maybe form action="/employee-app/" method="post" I get a 500 with both of the above. I seems like Orion is finding things okay because I get this message when it starts up Auto-unpacking D:\Personal\Proto\CodeGen\Employee3\rel\employee-app.ear... done. Auto-unpacking D:\Personal\Proto\CodeGen\Employee3\rel\employee-app\employee-app -web.war... done. Auto-deploying employee-app (Assembly had been updated)...
