When to use a JMS Bridge and when to use a Proxy

Hi,
We currently are running an OSB with most connections coming in via MQ to a JMS queue. We've been asked to implement a JMS Bridge.
Wen using a messaging bridge to a foreign provider, the documentation recommends using the Foreign JMS option to simplify the creation of bridge destinations anyway.
The key difference with using the bridge, is that you remove responsibility for the network transfer of messages from OSB's proxy and give it to the bridge. However, this now means that the messages are stored in WebLogic JMS with all the implications that brings. Is that really what you want? Isn't the whole point of MQ to be your reliable messaging service and not to use WebLogic JMS instead/as well?
But the Solutions design team mention
Without bridge
MQ >--------Receive -------->---------Send ---------> JMS
| ....... Transaction 1 ....| .....Transaction 2 ......|
With bridge
MQ >--------Receive -------->---------Send ---------> JMS
| ....... ............Transaction 1 .......... ......|
Is this true, so we have to use a bridge?

I think your solution design team is wrong..
MQ --> OSB Proxy Receive ---> OSB Proxy Send --> JMS will be a single XA transaction.
An OSB proxy is preferred in this case for the following reasons:
1. Don't use bridge for receiving messages . Bridge should be used rather for sending messages to non highly available remote messaing providers. Even for this case weblogic recommends SAF .
2. Whatever the savings on transaction as mentioned by your design team doesn't appears to be correct.
3. Weblogic messaging bridge appears to be a buggy product. You will have to apply a couple of patches to make the bridge to work as expected. It will take some time to stabilise it in a production environment. Weblogic's EJB container is much stable and with MDB's it would be less prone to bugs. This is from my personal experience. Others might have a different experience.
4. You can leverage the out of box monitoring facilities provided by OSB. This can give you stats of how many messages were transferred between MQ and JMS, average & max response time etc.

JMS bridge and MQSeries. looking for statistics

          Hi !
          I have to use Weblogic 7 SP4 in cluster with a distant MQSeries queue manager.
          I know I can't have a "exactly once" quality of service. I use a MDB (deplyed
          on each instance of the server).
          I'm looking for statistics about how often a message can be treated 2 (or more)
          times.
          Thanks a lot for any help !
          Florent


Hi Florent,
          Since these are MQ messages, it might be possible to find
          such statistics in MQ. Also, I think that MQ stores a
          redelivery count in their messages - so you can likely
          instrument your application code to get at the count.
          Note that 7.0 actually does support exactly once with WL MDBs driven
          by MQ. If you use transactions you can infer some stats on redeliveries
          by checking the relevant transaction statistics for rollback counts.
          I'm attaching some notes on JMS integration for your
          convenience.

          JMS Integration of Foreign Vendors with BEA WebLogic Server
          The following notes are derived mostly from "http://dev2dev.bea.com/technologies/jms/index.jsp".
          For additional questions, a good forum for WebLogic questions in general is "newsgroups.bea.com". These can be mined for information by using Google's newsgroup search function.
          JMS Integration Overview
          - For integration with "non-Java" and/or "non-JMS" platforms, see "Non-Java Integration Options" below.
          - For a foreign JMS vendor to participate in a WL transaction it must support XA. Specifically, it must support the javax.jms.XA* interfaces.
          - In WL versions 6.0 and up it is possible to make synchronous calls to foreign JMS vendors participate in a WL transaction as long as the foreign vendor supports XA.
          - WL 6.0 and 6.1 MDBs can be driven by foreign vendors non-transactionally. They can be driven transactionally by a select few foreign vendors (MQ is not part of the select few)
          - WL 7.0 and later, MDBs can be driven by foreign vendors transactionally and non-transationally.
          - WL 6.1 and later WL provides a messaging bridge feature. Messaging bridges forward messages between any two JMS destinations, including foreign destinations, and can transfer messages transactionally or non-transactionally.
          - WL 8.1 JMS provides additional features that simplify transactional and JNDI integration of foreign vendors. See http://edocs.bea.com/wls/docs81/jms/intro.html#jms_features
          Integration with 8.1 Details
          A good overview of 8.1 JMS interop capability is the presentation "Integrating Foreign JMS Providers with BEA WebLogic Server" here:
          http://www.bea.com/content/files/eworld/presentations/Wed_03_05_03/Application_Servers/1097-Foreign_JMS_Providers_WLS.pdf
          This document refers to helpful new 8.1 features, which simplify integration. These include:
          http://edocs.bea.com/wls/docs81/ConsoleHelp/jms_config.html#accessing_foreign_providers
          http://edocs.bea.com/wls/docs81/jms/j2ee_components.html#1033768
          And are also summarized here (under interoperability):
          http://edocs.bea.com/wls/docs81/jms/intro.html#jms_features
          Also read the extensive MDB documentation, which extensively covers integrating foreign vendors:
          http://edocs.bea.com/wls/docs81/ejb/message_beans.html
          The 8.1 features are likely sufficient for most 8.1 integration needs, and you may not need to refer "Using Foreign JMS Providers With WLS" white-paper mentioned below.
          Integration with 6.1 and 7.0 Details
          Read the "Using Foreign JMS Providers With WLS" white-paper:
          http://dev2dev.bea.com/products/wlserver/whitepapers/jmsproviders.jsp
          Note that this white-paper does not take into account 8.1 features.
          For 7.0 read the extensive 8.1 MDB documentation, which largely also applies to 7.0:
          http://edocs.bea.com/wls/docs81/ejb/message_beans.html
          Non-Java Integration Options
          - WL JMS has a JNI based C client which is available for Windows and some UNIX platforms. This C client supports 7.0 and up, and will be officially packaged with WLS in 9.0 (virtually unchanged). The C API is currently only supported through the jms newsgroup. See "JMS C API", here:
          http://dev2dev.bea.com/technologies/jms/index.jsp
          - WL supports direct Windows COM access through its "JCOM" feature. This doesn't include the JMS API, but one can invoke EJBs which in turn invoke JMS. See
          http://e-docs.bea.com/wls/docs61/jcom.html
          http://e-docs.bea.com/wls/docs70/jcom/
          http://e-docs.bea.com/wls/docs81/jcom/
          - Similar to JCOM, but more advanced, WL supports IIOP standard based access on multiple platforms. You can use the BEA Tuxedo C client for this purpose (no license fee). This doesn't include the JMS API, but one can invoke EJBs which in turn invoke JMS. See
          http://e-docs.bea.com/wls/docs81/rmi_iiop/
          http://e-docs.bea.com/wls/docs70/rmi_iiop/
          http://e-docs.bea.com/wls/docs61/rmi_iiop/
          Unlike most other approaches, the IIOP client approach also allows the client to begin and commit user (JTA) transactions (not configured).
          - If you already have a BEA Tuxedo license, one option is communicate through BEA Tuxedo (which has various APIs on Windows) and configure a WebLogic Server to respond to these requests via the WTC bridge. Search for "WTC" in the BEA docs. Unlike most other approaches, the Tuxedo API approach also allows the client to begin and commit user (JTA) transactions.
          - Another approach is to interop via web-service standards. Or even to simply to invoke a servlet on the WL server using a basic HTTP call from Windows. These in turn can invoke the JMS API. There is a white-paper on "Interoperability Study of BEA WebLogic Workshop 8.1 and Microsoft .NET 1.1 Web Services", that demonstrates web-services here:
          http://ftpna2.bea.com/pub/downloads/WebLogic-DotNet-Interop.pdf
          - Yet another approach is to use a third party product that is designed to wrap any JMS vendor. There are even open source versions. In no particular order, here are some examples: Open3 WinJMS, CodeMesh, Active JMS, SpiritSoft
          - Finally, there are .NET/C/C++ integration libraries that not specific to JMS, some examples are JNBridge, Jace, and CodeMesh.
          Notes on MQ Remote Capable XA Clients
          Until recently, IBM MQ JMS clients could not work transactionally unless they were running on the same host as their MQ server. This is a limitation unique to MQ that was relaxed with the introduction of IBM's new "WebSphere MQ Extended Transactional Client". See:
          http://publibfp.boulder.ibm.com/epubs/pdf/csqzar00.pdf
          The product is new, and for some reason, configuration of this client seems to be tricky, even when WebLogic is not involved at all. Oddly, the main sticking point seems to be simply making sure that class paths refer to the required IBM jars:
          - Required on WLS where MQ objects are bound into JNDI:
          com.ibm.mq.jar, com.ibm.mqjms.jar
          - Required only if MQ objects are bound into JNDI on a different server:
          com.ibm.mq.jar
          If there are problems when using this client, first get it to work using a pure IBM client without any BEA classes involved. Once that is working, search the WL JMS newsgroup for answers and/or contact BEA customer support.
          Notes on Oracle AQ Integration
          If problems are encountered integrating Oracle's built-in queuing (Oracle AQ) JMS client, there is publicly available wrapper code that can aid integrating AQ directly into MDBs, JMS, or the messaging bridge. The solution is titled "Startup class to bind AQ/Referenceable objects to WLS JNDI", is not supported by BEA, and is posted to:
          http://dev2dev.bea.com/codelibrary/code/startupclass.jsp
          Caveats:
          The solution doesn't directly support concurrent consumers. Perhaps Oracle requires that concurrent consumers each have a unique JMS connection? As a work-around, parallel message processing can be achieved indirectly by forwarding AQ messages into a WL JMS destination - which do support concurrent processing.
          Up-to-date versions of Oracle may be required. For more information, google search the weblogic.developer.interest.jms newsgroup for "Oracle" and "AQ".
          The solution doesn't seem to support transactions, it may be possible to extend it to do so.
          MDB Thread Pool Notes
          WL7.0SP? and WL8.1 and later support the "dispatch-policy" field to specify which thread pool an MDB uses to run its instances. In most cases this field should be configured to help address potential performance issues and/or dead-locks:
          http://edocs.bea.com/wls/docs81/ejb/DDreference-ejb-jar.html#dispatch-policy
          (Note that "dispatch-policy" is ignored for non-transactional foreign vendors; in this case, the MDB "onMessage" callback runs in the foreign vendor's thread.)
          MDB Concurrency Notes
          Queue MDBs driven by foreign providers can run multiple instances concurrently. Topic MDBs driven by foreign providers are limited to one instance (not sure, but transactional foreign driven topic MDBs may not have this limitation). The size of the thread pool that the MDB runs in and the "max-beans-in-free-pool" descriptor limit how many instances run concurrently.
          Design Guide-Lines and Performance Tuning Notes
          The "WebLogic JMS Performance Guide" white-paper contains detailed design, performance, and tuning information for Clustering, Messaging Bridge, JMS, and MDBs.

WLS JMS bridge not forwarding mesages

Hi All,
I want to send messages from a queue in the source weblogic domain to the target queue in another weblogic domain. Both the domains are weblogic server. On the source server agile PLM is deployed. For this communication I established JMS bridge and JMS destination on my source server. The resource adpater is deployed and active. But my bridge is not working. Is not forwarding message to the target queue on the target server.
I inspected the log files. I found the following error
"<BEA-190032> << eis/jms/WLSConnectionFactoryJNDINoTX > ResourceAllocationException thrown by resource adapter on call to ManagedConnectionFactory.createManagedConnection(): "javax.resource.ResourceException: ConnectionFactory: failed to get initial context (InitialContextFactory =weblogic.jndi.WLInitialContextFactory, url = t3://<target_server_ip>:<port>, user name = null) "> "
Also on the monitoring tab of the JMS bridge initially it was showing message "Failed to look up the source adapter" then I deployed the resource adapter. Now on the monitoring tab its showing the message "Connected to the source" instead of shoing "Fowarding Messages" . can anyone tell me what could be the cause. Please help its really urgetnt!!!
Can anyone please tell me what can be the issue?
Thanks in Advance!!

Could you please provide the way you used the connection factory?
I am concerned about *(InitialContextFactory =weblogic.jndi.WLInitialContextFactory, url = t3://<target_server_ip>:<port>, user name = null) "> "*
Please check.

You can associate files from the Bridge level and the Desktop level.
In Bridge CS4, go to Preferences > File Type Associations and change it to Photoshop CS4 for the file types you want.
If you want to open files from the Windows Desktop in CS4, these are the instructions:
Do this from the Windows Desktop:
If you want your image file to open in Photoshop and it doesn't, right click on it and choose

hi jeff
I've seen random crashes on closing and random freezes with a new box and 10.5.6. There are a couple posts here about stability issues, I'm not sure where the problem is, PS, OS, fonts, who knows, but there's something going on.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

I had to reinstall CS4 and now have error messages when opening bridge and photoshop

The error message is "The specified module could not be found. C:\Program Files (x86)\Common Files\Adobe\Adobe Version Cue CS4\Client\4.0.1\Version Cue.DLL

I tried what you suggested and it did not help. whenever I try to open either photoshop or bridge, I get a message saying that there was a problem loading scripts the last time that Bridge was open and do I want to try loading them again? If I click yes, I get that same error message that I reported in my original question and photoshop/bridge will immediately close. If I click no, photoshop and bridge will open but it will not let me open a raw format document. It seems like Adobe Camera Raw is not being recognized.   One of the updates I downloaded was an update to Adobe Camera Raw so the functionality is there, it just can't be accessed. do you think I should try to uninstall and re-install Photoshop again?

Adobe Bridge and CS5 open when iPad connected

Why does Adobe Bridge and Downloader open when I connect my iPad? I cannot find in Preferences any way to toggle this off. HJZ
Message was edited by: Harry Zemel1

The same thing happens when you connect an iPod Touch.
Here's the solution:
1) Plug in your device; when Adobe Bridge pops up, just close them.
2) Open Image Capture app on your Mac (not sure about PCs), bottom left side says, "Connecting this (insert device name here ie. iPod or iPad) opens:"
3) select No application.
Done!

I just made the switch to mac. I am have installed all the new PS6 CC and bridge and I am now trying to add some presets to my ACR but when I search for the folder to place them it is not there. From what I researched it says it should be under camera library/application support/adobe/camera raw/settings but I can only get to library/application support/adobe/ and then there are two different camera raw options I have checked both and there are not settings folder. If anyone can help me please thanks

Apple most likely has the same poor taste that Microsoft does when it come to defaults. Microsoft likes to hide things like settings, preset, folders etc from normal users think the dumb or something else. If Apple also hide things you will have to make some system setting changes that will allow Finder to do it job and find it for you.

Wheh to use abap proxy and when to use idoc

Hi All,
Please provide some clarifications for the below points :
What is Sproxy?
2.     Why we are using Sproxy instead of Idocs
3.   When we are going Proxy ?
4.   What are the types of proxy ?
5.   How to Create to Proxy ?
6.   What the Difference between SProxy and Idocs
   7.   What is SOAP file? When we are using SOAP file ?
Thank you.
Regards,
Bharat

Hi Bharat,
You seem to have a range of Questions. I will try and answer as many as possible.
What is Sproxy?
SPROXY is a transaction [T-Code] on the SAP ECC/CRM etc side where you can see the objects designed in SAP PI ESR and develop its corresponding ABAP code. SPROXY T-Code displays the Service Interface. You can read more about it in the following site:
**************** - XI - ABAP Proxy communication
2.     Why we are using Sproxy instead of Idocs
For Certain implementations Standard IDocs may not be available and it is quite tedious to create a Z- IDoC and therefore it is advantageous to use Proxy. You can read more about this doubt in the following links:
Choosing to use IDOC standard or ABAP Proxy?
IDOC vs Proxy
ABAP Proxy Vs IDOC
3. When we are going Proxy ?
When there are no Standard IDocs available. Please refer above links to get an answer for this.
4.   What are the types of proxy ?
5.   How to Create to Proxy ?
Again the following link has the answers for both these questions:
**************** - XI - ABAP Proxy communication
6.   What the Difference between SProxy and Idocs
Difference is in the way the communication happens. Standard Idocs are already provided and you can use them directly while Proxy you will require to write the code on ECC side. You can refer the following link to understand more:
Advantage of ABAP proxy over BAPI
7. What is SOAP file? When we are using SOAP file ?
I have not heard of anything called SOAP file. SOAP is a protocol used for communication and you can send files as attachment in your SOAP to Any(file/idoc/Soap etc) or vice Versa Interfaces. Infact Proxy itself is SOAP based communication with XI 3.0 Protocol.
Please explore SCN to know more about the various scenarios. There are endless possibilities in SAP PI.
Hope this Helps.
Thanks & Regards,
Tejas Bisen
