Flex and EJB with JBOSS

Hi!
I have a web application running on JBOSS 4.0.4 and using EJB/EJB3.
The main goal is simple, i need to substitute some JSP pages with flex.
I'm a total newbie with flex and i don't even know how to get started.
What do i need? Only BlazeDS or something more? Is there some tutorial with a step by step explanation?
I appreciate your help.

You cant really replace Struts with Flex, maybe a view part
, thats about is, you still need backend processioning
logic,all that you are asking is difficult to answer is one reply,
IMHO, best thing you can do is to dive into following URLs :

Error trying to get LiveCycle ES up and running with JBoss/SQL Server

I am having an error trying to get LiveCycle ES Trial up and running with JBOSS and SQL Server. The LiveCycle ES and JBOSS engines are running on Windows Server 2003 SP #2 under VMWare Server with 2 vCPUs/1 GB vRAM. The SQL Server database is SQL 2005 x86-64 with SP #2 on a separate server. I have carefully followed all of the instructions for setting up jboss, modifying all of the appropriate XML files, downloading the SQL JDBC drivers and putting it in the %JBOSS_HOME%\server\all\lib directory, etc. I tried both the SQL JDBC 1.1 and 1.2 drivers and they both fail. The error I get is on startup of jboss using cmd /c start /low run.bat -c all (and yes I also just tried run.bat -c all) it runs along file until it gets here 2008-06-18 16:00:03,123 INFO [org.jboss.resource.connectionmanager.ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=IDP_DS' to JNDI name 'java:IDP_DS' 2008-06-18 16:00:03,123 INFO [org.jboss.resource.connectionmanager.ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=EDC_DS' to JNDI name 'java:EDC_DS' 2008-06-18 16:00:03,373 INFO [org.jboss.resource.connectionmanager.ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=ConnectionFactoryBinding,name=JmsXA' to JNDI name 'java:JmsXA' 2008-06-18 16:00:03,373 INFO [org.jboss.resource.connectionmanager.ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=ConnectionFactoryBinding,name=adobe_JmsQueueXA' to JNDI name 'java:adobe_JmsQueueXA' 2008-06-18 16:00:03,389 INFO [org.jboss.resource.connectionmanager.ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=ConnectionFactoryBinding,name=adobe_JmsTopicXA' to JNDI name 'java:adobe_JmsTopicXA' 2008-06-18 16:00:03,482 INFO [org.jboss.resource.connectionmanager.ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=DefaultDS' to JNDI name 'java:DefaultDS' 2008-06-18 16:00:03,514 WARN [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Throwable while attempting to get a new connection: null org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Failed to register driver for: com.microsoft.jdbc.sqlserver.SQLServerDriver; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: com.microsoft.jdbc.sqlserver.SQLServerDriver)) at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.createManagedConnecti on(LocalManagedConnectionFactory.java:164) [ lots more error scrolls ] this repeats multiple times I can see that it does acknowledge that I put the sqljdbc.jar file in the appropriate directory from the boot.log <snip> 15:59:44,856 DEBUG [SARDeployer] deployed classes for file:/C:/jboss/server/all/lib/sqljdbc.jar <snip> please help!

APJ We ran into many issues setting up a very similar environment. In the end we had to use a specially configured JBoss, supplied by Adobe, to make a connection with the SQL database. Since you have SQL w/ SP2 on it, you will need the 1.2 driver for sure, but you may want to talk to Adobe support about obtaining the version of JBoss they supplied us with. The Adobe Support Reference Number is: 1-52422366. Even with the alternate JBoss we had to perform the following steps to get the configuration right: 1. Install Livecycle from the installation DVD. Follow the instructions for installing LiveCycle supplied by Adobe, including all pre-installation instructions. Make sure NT service is installed with parameters, and dont run Configuration Manager. 2. Rename %LIVECYCLE_INSTALL%\jboss to %LIVECYCLE_INSTALL%\jboss_orig 3. Extract the zipped new, good instance of JBoss (supplied by Adobe) to the %LIVECYCLE_INSTALL%\ folder 4. Go to the %LiveCycle_Home%\deploy folder and make a copy of the file adobeimport_SQLServer.jar file. Rename the copy of the file to aadobeimport_SQLServer.jar. There seems to be a bug in configuration manager that looks for a file with the extra a appended to the beginning of the file name, where that file normally isnt there. Make sure that the adobeimport_SQLServer.jar file is still in this folder as well. 5. Edit the data source file (%JBOSS_HOME%\server\all\deploy\ adobe-ds.xml) to point to the correct database for the LiveCycle Server. a. Update the <connection-url>, <user-name>, and <password> tags with the correct database connection information. b. If BAM is to be used on the server (this should be done on the Production server) then delete both lines that state Remove this line, if BAM is used. 6. Go to the login configuration file (%JBOSS_HOME%\server\all\conf\login-config.xml), and edit the section labeled <application-policy name = "MSSQLDbRealm">. a. Change the Principal, UserName, and Password options to point to the correct database. These will be the same as what was changed in the adobe-ds.xml file from the step above. 7. Edit the system variables on the server. Add to the Path variable %JBOSS_HOME%\bin, and add the variable JBOSS_HOME with the path to the JBoss folder on the server. (D:\Adobe\LiveCycle8\jboss for example) 8. From windows services start the JBoss for Adobe LiveCycle ES v8.0 service. Review the JBoss server log (%JBOSS_HOME%\server\all\log\server.log) to verify that JBoss starts without throwing any exception errors (A document timeout exception is the only acceptable exception for starting the service). 9. Run the LiveCycle Configuration Manager (%LiveCycle_Home%\ConfigurationManager\bin\ConfigurationManager.bat). a. Select to Not Upgrade fromLiveCycle 7.x. b. Check all boxes on the Solution Component Selection screen. c. For the Task Selection screen check all the boxes except for the Import LiveCycle ES Samples into LiveCycle ES if on the production server. d. Run through the rest of the configuration manager interface to setup the LiveCycle server with the new application server. Follow the steps supplied by Adobe for this. 10. Once configuration manager has completed, reboot the server, and verify that JBoss starts up again without any exceptions or errors (again a document timeout exception is an acceptable exception. Look at the server log to verify this (%JBOSS_HOME%\server\all\log\server.log)).

Sun RI and MyFaces with JBoss AS

Hi all,
I am using JBoss AS and have a JSF application. By default, JBoss bundle MyFaces JSF with Jboss. I have everything working fine with MyFaces. However, I encounter problem when I tried to display the banding for dataTable using Oracle ADF. From my research, it seems ADF table's banding does not work with MyFaces so I want to test out using Sun RI JSF with Jboss. I remove MyFaces jar files and put Sun RI jar file in WEB_INF/lib directory and remove the line in web.xml
<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>
This is done following Jboss documentation. But when Tomcat starts up, it seems still look for org.apache.myfaces.webapp.StartupServletContextListener class and throw ClassNotFoundException (because I removed myfaces jars). Has anyone benn able switched to use Sun RI in JBoss AS version 4.0.5?
Thanks a lot,
LNgo

Hello Raymond,
I must say that I downloaded the JBoss Portal Binary and not the bundle JBoss AS + JBoss Portal, because I already had a JBoss AS working, so it was the best way to do it (as it is said in the JBossPortalReferenceGuide). I have both things (server and portal) in the same directory, but I don't know if maybe one of them should contain the other (I have seen that in the bundle, the portal directory contains the JBoss application server) When I downloaded the JBoss Portal and tried to deploy it by directing my web browser to http://localhost:8080/portal it did not work, so I decided to copy the jboss-portal.sar directory from the JBoss Portal to the deploy of my server. Maybe this was a mistake.
But anyway I have seen that JBoss Portal 2.6 comes with the myfaces jars, and as JBoss AS 4.2 uses Sun RI by default, it is going to collapse anyway. Should I just remove these jars from the portal? As I told you before, I tried doing it and I got two errors of not found classes.
Please, any help would be really appreciated, I am losing a lot of time with this bug, because the server keeps getting out of memory due to it.
Thanks in advance.

Flex and CFC with Remote Object

I wrote a simple cold fusion componenet on my webserver at:
http://www.paramountmediainc.com/webservices/eadexchange/agent_sys.cfc
Now I want to play with that in Flex with a Remote Object.
I'm writing the flex on my local machine. I tried this approach but
was uncessfull:
<mx:RemoteObject id="acctRO" showBusyCursor="true"
source="webservices.eadexchange.agent_sys"
endpoint="
http://www.paramountmediainc.com/flashservices/gateway">
I get the following error ...
TypeError: Error #1034: Type Coercion failed: cannot convert
Object@3b15da1 to mx.messaging.messages.ErrorMessage.
Any ideas what I'm doing wrong here?

Spatial Data in EJB with JBOSS

Hello,
how do I handle Entity Beans with spatial fields (type sdo_geometry)to JBoss?
I have problems to insert data this way: I get
an SQL-Exception "Invalid column type"
I think the problem is the jdbc-datatype mapping in JBoss (jbosscmp-jdbc). No matter which jdbc-type I use, the exception occurs anyway.

Hi Syedurur,
You may be in the wrong forum as OBIEE only utilizes MapViewer as far as I know.
MapViewer
So as Stefan notes, you are not going to be able to use SDE.ST_GEOMETRY with OBIEE as its not an Oracle product. However, your ArcSDE registered MDSYS.SDO_GEOMETRY geometry should work fine. Yet in your example you posted you seem to have Web Mercator (3857) ordinates but the SDO_SRID is WGS 84 (8307) so that is mangled and not going to draw anything correctly. Try changing the SDO_SRID to 3857.
Now Stefan is a bit incorrect about the ease of moving from SDE.ST_GEOMETRY to MDSYS.SDO_GEOMETRY. The folks at ESRI make it simple to move in the other direction but - surprise! - not to move away from their proprietary spatial type.
ArcGIS Help (10.2, 10.2.1, and 10.2.2)
Now you can still accomplish this by exporting your data from the geodatabase and then importing it back in as SDO but that is certainly not as simple as using the above one-step migration tool.
In theory you could convert SDE.ST_GEOMETRY to MDSYS.SDO_GEOMETRY on the fly in the database with SQL. Both ESRI and Oracle proudly spout their unwavering support for OGC standards. Thus this should work
SELECT MDSYS.SDO_GEOMETRY(SDE.ST_AsText(a.shape),8307) FROM my_ESRI_ST_GEO_table a;
(Note change the 8307 to the matching Oracle SRID of your data)
But my experience was that the very old Oracle Java WKT parser mixed with the somewhat non-standard ESRI External DLL WKT writer is not a very reliable combination. But do give it a try and feel free to report back to us how it goes. I really have not tried this in a couple of years so perhaps things are better now.
Cheers and Happy New Years,
Paul

Flex and Seam

Do you think it may be possible to integrate Flex Data
Services with JBoss's Seam framework?
Thanks,
Pepe.

> Seam?
Yes.
> It looks like you'd be shoe horning Flex into an MVC
> that was designed to be page controller based
JSF is a component based framework not an MVC framework a la
Struts.
> with all the page refreshes of the early 2000 web era.
In fact, Seam's livecycle is much near to Flex's that what at
first sight may seem.
Seam Remote, which is an AJAX remoting framework, allows to
call EJBs methods
directly from Javascript => no page refreshes.
What I was asking with this open question is if someone has
tried to develop an
EJB3Adapter or SeamAdapter that synchronizes the FDS
framework with the workflow part of Seam.
OTOH a JSF render kit for Flex, if something like that is
possible, would be a cool path to explore.
Regards,
Pepe.

Deployment Isssue with Jboss and Blazeds

Hi,
I was trying to deploy Blazeds over Jboss 4.0.5.GA , for that i copied blazeds.war, ds-console.war and samples.war to Jboss deploy folder and restarted my jboss server.
when i'm trying to access samples application by using url http://localhost:8180/samples it is throwing
The requested resource (/ds-console/) is not available. exception
at Jboss console i'm geeting below error with all the three wars i deployed earlier
status: Deployment FAILED reason: flex/messaging/MessageBrokerServlet (Unsupported major.minor version 49.0)
state: FAILED
watch: file:/C:/SabaWeb/JBoss_Tomcat/server/default/deploy/blazeds.war
altDD: null
lastDeployed: 1256250757909
lastModified: 1256250757878
I think that is because of i'm not using jdk 1.5 or jboss 5 insted i'm using jdk 1.4 because of some dependency for my existing application
Please let me know which version of blazeds should i use for the above configuration (jboss 4.05 with jdk 1.4) or blazeds is not supported for jdk 1.4 at all
the version i tried was blazeds-turnkey-3.2.0.3978
Thanks,
Anuj

Remove all spaces from the directory path of where jboss is installed.
E.g. change
"c:\my docs\my boss dir" to
"c:\mydocs\myjbossdir".Strange I know. It appears to be an Eclipse issue rather than a jboss issue.
Cheers
Steve
P.S. You might have to change the server timeout to > 50secs (double click on server entry from within Eclipse (Ganymede)).

Problem in creating client side PDF with image using flex and AlivePD

I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance
Atishay

I am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing?

Silent print a PDF from a web page using Flex. We are targeting Windows and Mac with Arcobat reader installed

We are planning to Silent print a PDF from a web page using Flex. We are targeting Windows and Mac with Arcobat reader installed. I have tried using the AIR appliaction and it worked, But our requirement is NO INSTALL to the user machine for the silent printing. It is just from web page and silent printing to the default printer to the desktop/Laptop. Can anyone share your thoughts and experience with us. It will be very helpful..
For AIR : I tried the thread Re: AIR and PDF showing/silent printing

Hey CodeMonkey & Ross,
Did you either of you ever find a solution? I'm stuck too, it seems I can get remote printing on all these PDFs to work but it just prints a blank page since I've been using Javascript in the browser, not Adobe's (they are Engineering drawings that I do not have permission to edit so I can't just insert code into them but I need to make work instructions). I've been scouring the internet for hours now, it seems that this thread is the only relevant/useful one at this point. No one else was trying to achieve this for similar reasons to mine.
Thanks guys,
Lox

EJB with JAVA 2 and 8i 8.1.5

Hello,
we have a problem with EJB , JDeveloper 3 and 8i (8.1.5). The FAQ states, that the client JDK must be 1.16 and the with the ORALCE 8i classes are only runnable under this JDK. When we want to use JDK 2 we need to use 8i Version 8.1.6.
How can we get the ORACLE 8i 8.1.6 client classes, without downloading the whole 8i 8.1.6 ORACLE Server? Is there any ftp server with only the client classes on it? Can anybody help?
Thankx in advance
Sven

mtomlins: No - why should it not make sense to have JDK 1.2 only on the client?! The JServer FAQ says this works, if you have the 8.1.6 client classes. On the 8.1.5 server you can use only JDK 1.1, of course.

Thanks, Flex harUI, for the direction in regards to isolating build changes. That aside (still working on it), can you offer any direction in regards to my original question on SDK and AIR compatibility? I'm specifically looking for a version compatibility mapping or anything that definitively states, "Flex SDK x.y.z works with the following versions of AIR". This information is crucial for us in order to more specifically plan our own roadmap built upon these two frameworks as we consider both existing installations of our software and future distributions.

Getting Started with Flex and Java RPC for Free?

Good Morning,
Please forgive me if this is the wrong place to post- I'm
just having trouble wrapping my head around what is and what isn't
available for free in the Adobe Flex world.
I've been working on an application for the last few months
using Open Laszlo (
http://www.openlaszlo.org/),
but I've been running into frustrations with their lack of
up-to-date documentation, and I've found it difficult to bring new
people into the project, since the set of users who know it is so
small.
While I do like that I can compile to DHTML, that's not
enough to hold me there.
I've been looking into Adobe Flex, and it seems like a good
alternative- I'm comfortable paying $500 for the IDE-
I use Eclipse currently, so having a plugin for it sounds
ideal. That said, when I look into ways to talk to a Java backend,
everything points to Flex Data services, which is now part of some
larger package costing tens of thousands of dollars.
I don't need advanced messages, or data synchronization, as
nice as it would be.. All I really need is the ability to call a
Java method, and get an object back, which I can then work with in
Flex.
I see the forum message that asks
"How
do I 'do' Flash for free?, but this only talks about RPC very
broadly. Given that the message is from over a year ago, I thought
it would be better form to start a new topic, than replying to it.
Can someone explain to me what components I'd need, both on
the client side and the server side?
Is there a set of manuals that explain how to do Flex RPC
from Java?
Can Flex compile to any versions of flash earlier than 9?
(Flash 6/7 is still in wide deployment)
Do I want to start using Flex 2, or Flex 3? Are the
components compatible? Will the F3 docs be ready?
Finally, where can I purchase the Charting components? The
ability to create charts such as
this
overcome a decent price barrier.
Thank you for any insight you can offer, and direction you
can provide.

when they did it).
What did the RMI talk to? Are there docs on this?

Another approach, generate the proxy from the java
interfaces. Or better yet, generate it dynamically with CGLIB.

Finally, I'm investigating using Mule for the integration.
Let me know what you think about those suggestions.
We have our own messages, but how would MULE translate them

You know quite a bit more about this, can you take a step

Problem with Stateful EJB in JBOSS

Hi,
J have a problem with invoking stateful EJB methods from my web application deployed in Jboss 4.0.5.GA both. The same EJB with WebLogic functions perfectly, instead with Jboss it often throws the following exception:

Is there someone can help me?
thanks forward.

 We got resolved it through bea. This is a know problem of WLS6.1 Sp4. Bea has provided
 us with a patch, after which every thing seems to be working fine.
 Please open a case with bea mentioning the CR092146. You can read the description
 of this CR on internet.
 This will certainly solve your problem.

Creating SSL certificate and configuring it with JBOSS 4.0.1

I have to post some data to a secured site from my application.
For this, I am creating connection to that site using URLConnection and to send data I create OutputStream using the connection.
But, while creating the stream it is showing SSLException and message is No trusted certificate found.
For this, I need to create SSL certificate (mostly using keytool command) and configure it with my application server which is JBOSS 4.0.1
Now, my problem is that I don't know the exact steps to create a certificate and configure it with JBOSS. Please provide the steps in detail.

I think you have this back to front. Unless this exception came from the server, in which case it is misconfigured, you don't have to create a certificate, you have to import the server's certificate, or that of one of its signers, into the client's truststore, and tell Java where the truststore is if it's in a non-standard location.
See http://java.sun.com/j2se/1.5.0/docs/guide/security/jsse/JSSERefGuide.html. You'll have to ask about the JBoss part in a JBoss forum.
