Oracle App Server 10.1.3 - IBM MQ 6.0 Msg Redelivery Issue

Hi All,
I have an application which sends message to the Queue configured in MQ. I have
an underlying MDB to receive the messages from the MQ. In some of the business
scenario i am getting an error during processing of the message and MDB doing a
rollback properly.
But the messages are not being moved to the inbound queue again. If i am
stopping the MDB the messages are moving to a inbound queue. I guess i have to
configure some MDB related parameters.
Kindly let me know how and where to configure the parameters if any.
Waiting to hear from you.
Thanks and Regards
Prasanna.

However, the appropriate jar is bundled with the ejb and is also in the applib dir.
Should I add it to the classpath for the server and if so how?How did you bundle it with your ejb jar? Did you do anything particular when deploying it?
I strongly recommend you that you read the chapter 3, Utilizing the OC4J Class Loading Framework of the book "Oracle® Containers for J2EE Developer's Guide", especially the section "Troubleshooting Class Loading-Related Problems in OC4J" if you have not done so. You will see pretty much everything you need to konw about classloading in oc4j.

Oracle App Server 10.1.2.0.2 operability with Axis SOAP engine

Hi We are planning to deploy client stubs generated using the WSDL2Java tool as provided by Apache Axis, i.e., we would be writing the client side logic for invoking a web service deployed on a different server. For this we are using Axis engine to generate stubs and we write our own JSP/HTML pages and deploy this on Oracle App Server 10.1.2.0.2. Is their any issue in adopting this approach. Is Oracle App Server 10.1.2.0.2 compatible with Code created using Apache Axis?

There was a blog that described some level of Axis use with what looks like OC4J 9.0.4 -- so that should extend to 10.1.2. since they are essentially the same thing.

Oracle App Server 10.1.2 (Windows) with STAF

I'm trying to run STAF in a servlet in OAS and STAF has a jar named JSTAF.jar that further uses some dll files. Oracle App server is not able to load the dll files. To overcome this i specified -Djava.library.path=<dll files directory> in the server properties but now OAS is able to load some of STAF dll files but it still gives the following error. Please Suggest are there any options in OAS to make it load all the dll files.:

we have Oracle App Server on Windows server 2003, new installation.
plz help me with this problem.

Not sure why you exeucute opmnctl validate, but
C:\product\10.1.3.1\OracleAS_1\opmn\bin>opmnctl validate opmn.xml
LPX-00202: could not open "opmn.xml" (error 200)opmn.xml isn't in $OH/opmn/bin directory. It's in $OH/opmn/conf.
This is quite difficult to debug from this forum. Check the logs in $OH/opmn/logs and see if that helps. Also try to shut everything down (and check that all processes are gone) and then try to restart.

Oracle App Server 10.1.3.1 + Struts2 parameter map loss

hi,
I am facing an issue with oracle app server 10.1.3.1. With an application deployed in it, any .action hit seems to lose the parameter map. However, i m using Spring MVC with jasper reports for reporting purpose. So hitting a .report seems to go thru without the parameter map loss. I m using struts 2.0.11 in the application.
I have also tried the workaround related to struts.properties - (struts.dispatcher.parametersWorkaround = true). Did not help.
I wrote a CustomActionMapper which is an exact copy of DefaultActionMapper but for the addition of a few log statements to see the parameter map and uri.
I can notice the paramter map coming out empty even when data is posted or queryString with parameters sent.
Any leads on this truly appreciated.

Standalone webcache or Web cache from Oracle Apps Server 10.1.2.0.2?

Hi
I am installing web cache on two servers in web tier and J2EE server (with OHS) on another two servers in apps tier. Should I use standalone webcache or install from Oracle Apps Server package? If I choose Oracle Apps Server package, I have to disable Home, HTTP components. But it is DCM managed. Any suggestions?
And should I deploy my OHS servers on web cache servers in the web tier? In future we want to expand J2EE installation, we will deploy Portal with SSO, OID etc.
Regards
Shen Jie

Shen Jie,
Please review the Enterprise Deployment to see what are the best architectures.
Hope this helps.

I imagine you ended up having to upgrade 10gR2 to 10gR3 at least. Correct?

How to displays the standard open file dialog box in Oracle Apps Server

Hi,
I am having a form, where i am opening a file and putting that file content in a text box.
This is my code written in WHEN-BUTTON-PRESSED trigger:
declare
in_file Text_IO.File_Type;
linebuf VARCHAR2(8000);
filename VARCHAR2(30);
BEGIN
filename:=GET_FILE_NAME('d:\Rajesh\Practice', File_Filter=>'Text Files (*.txt)|*.txt|',select_file=>false);
in_file := Text_IO.Fopen(filename, 'r');
LOOP
Text_IO.Get_Line(in_file, linebuf);
:text_item5:=substr(:text_item5||linebuf||chr(10),1,5000);
END LOOP;
EXCEPTION
WHEN no_data_found THEN
Text_IO.Put_Line('Closing the file...');
Text_IO.Fclose(in_file);
END;
I have posted this in ORacle Apps Server.Where i was not able to get the Open Dialoq Box.It is giving an error as
"FRM-40735:WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-302000.".
I think the GET_FILE_NAME function is not supported in the Apps Server.
Is there any alternative solution for getting the OPEN DIALOG WINDOW in Oracle Apps Server?
Pls let me know.

A call to the file dialog box will call a modal system dialog. So LV can't go on executing VIs in the user interface thread."
Are you sure? I think, that File Dialog, called by LabVIEW File Dialog from Advanced File Functions Palette doesn't blocking any cycles in subVI, which running in UI Thread. Look in my old example (that was prepared for other topic, but may be good for this topic too).
2 linus:
I think, you must a little bit reorganize you application for to do this. You must put your File Dialog into separated cycle. This cycle, of course, will be blocked when File Dialog appear on the screen. But other cy
cle, which responsible for visualization will run continuosly at the same time...

Hi Cema,
Make sure that httpd.conf file (located at /ORACLE_HOME/Apache/Apache/conf ) has not changed.
Is your AS running on Linux? ".so" is used in case of linux only and for windows extension should be ".dll"
Please use the same if your http server is running on windows. HTTP Server documetation may have more details related to this.

Upgrading Oracle Apps Server from 10g (10.1.3.0) to 10.1.3.5

Have the following question.
First time upgrading Oracle Apps Server. So not that familiar in this area.
1. Step 6.1.2 in Oracle Application Server Patch Set Notes it says 
If you are applying 10g Release 3 (10.1.3) Patch Set 5 (10.1.3.5.0) to a 10g Release 3 (10.1.3.0.0) Oracle home and your system uses Enterprise Javabeans 3.0 applications, then you must undeploy your applications before applying the patch 
When I try to start Application Server Control I get the following error, please advice

Do we have to undeploye EJB3.0

Hi,
It seems like you are upgrading E-Business Suite . If thats the case its better post the problem in Ebiz forum. Also post the document id you are following, your app and db release, OS release. We do not deploy J2EE applications on Ebiz Tech Stack app server. So un-deployment should not be applicable here.

Apex Installation On Oracle App Server Apache

Installation using an existing Apache server like on the Oracle Apps Server can be done as a replacement for the Apache that is installed with Apex but may require the installation of mod_plsql into Apache.
If you need to do this, use the documentation for the Oracle Apps Server for installing mod_plsql. The Apex documentation assumes that mod_plsql is installed and is missing steps for a complete installation.
Installing on one web server is advantageous for applications that are integrated with Oracle App Server applications like the SOA Suite.

Use of Xerces Parser in out application with Oracle App Server 9.0.4

The problem in brief:
Our product is a web-app that runs under various Application servers.
One of our customers who uses Oracle App server, recently upgraded from 9.0.2 (9g) to 9.0.4 (10g), and our product no longer works with the latter version.
Our product uses XML parser Xerces 1.1.
In 9.02 it was possible to replace the App servers parser with Xerces 1.1. In 9.02 it was possible to replace the App servers parser with Xerces 1.1 (We modified the opmn.xml file, setting the Java options for our oc4j instance bootclasspath with xerces parser). Hence, our product works.
In 9.0.4, apparently, Oracle moved to a different parser, and it no longer allows the parser to be replaced. If the bootclasspath is modified with XERCES(tested various versions of xerces) parser, rightfully so ORACLE Application server does not start.
Unlike other prominent Application Servers (such as webshpere etc,) the Oracle application server does not support separate JVMs or namespaces for web-apps either.
We like, oralce application server, OC4J instance for our application to use the xerces parser version qualified with our product. We understand, replacing the XML parser for the entire Oracle Application Server is not supported function.
Since, Oracle Application Server is loading the oracle 'xmlparserv2' at system class path, though the applicaton has xerces.jar in application path (either in AppLib or web-inf/lib directory, Its not a class loading issue) it is not getting used (since javax.xml.parsers.documentbuilderFactory is mapped to oracle parser).
So, it looks like the only option available to us is to modify our product to use Oracle's XML parser. This is a major software change, and we want to keep it as last resort option.
Any suggestion and help will be higly appreciated.

Thanks for the intelligent posting on a difficult issue for you.
I wasn't aware of anything specifically being introduced that prevented the bootclasspath technique from working** in the 904 release.
For 904, the bootclasspath needs to be put in the start parameters tag of the java-options tag.
<process-type id="home" module-id="OC4J" status="enabled">
<module-data>
<category id="start-parameters">
<data id="java-options" ... -Xbootclasspath/a:/java/lib/xerces.jar"/>
</category>
</module-data>
</process-type>
You can also try copying the xerces.jar into the jre/lib/ext directory so it's loaded by the system classloader and see if that works**. This will put xerces at the extension level so
**these workarounds are not supported and will put you in an unsupported situation if a problem occurs.
The good news is that have taken steps to clearly enable the separation of container versus appplication class spaces in thenext production release (10.1.3) of OC4J. We will be providing a new classloading model which cleanly separates the two namespaces and allows applications to provide their own versions or distributions of class libraries with no collisions with the OC4J runtime libraries.
I don't know of any easy ways to do what you need -- other than reworking the app to use JAXP so that the parser implementation used is pluggable as you kind of allude to. If it was possible, I'd do that rather than hard coding in the use of the Oracle XML parser.
But just to reiterate, switching in xerces at the bootclasspath level is not a supported operation since it may have an effect on the OC4J runtime operation.

Can I use Oracle app server with mysql

Can I use Oracle app server with mysql. I seem to have the following error when trying to create a datastore. I have mysql.jar in my classpath. Can any one tell me what's wrong.
Error initializing data-source 'jdbc/topup': DriverManagerDataSource driver 'org.gjt.mm.mysql.Driver' not found

Yes you can forward requests from your own apache to the iAS. This can be done using mod_proxy. Some hints about how to do this are availlable on this forum.
mod_oc4j is not a standard apache module, and therefore is not availlable when you download apache. There is no apparent reason to use mod_oc4j on a "regular" webserver (unless you want to build your own iAS). Also there might be some licenseing issues with using mod_oc4j module on a standard apache.
You can encrypt data that is passed from a random Apache to you iAS.
