Dynamic configuration of applications

Hello all,
I've written a J2EE application in NWDS. In this app I have to do a http-call on the same server. Is it possible to get configuration parameter of the WebAS at runtime? I need some ports of my WebAS. I also need some configuration parameters from other running j2ee application. Is there a possibility to get them?
regards,
remo

Thanks for showing the possible direction. But, I don't think that a own MBean helps, because my app should work on every WebAS and the http-protocol runs not ever on the same port. To write this port in a own MBean for my app don't help for deploying the app on a other WebAS who the port is different. Or have I understood MBeans wrong?
What can help, is to query a existing MBean, but in which Bean is the http-port saved and how can I reach thie MBean?

Dynamic configuration of properties/descriptor files?

Hello all,
I am trying to use configuration files used in j2ee applications (property files, deployment descriptors) in a more dynamic manner. I have been searching for a suitable solution for some time now.
I have come across the following syntax within a configuration or properties file in a legacy project that I am to maintain.
<some-tag>
<some-config value=${theVariable}/>
</some-tag>
Notice the JSTL-like syntax ${theVariable}
The above code comes from an xreg config file, read at startup.
I do not think that there is custom code that parses the file so that it is updated, but I think that this is a pretty cool mechanism for dynamic configuration of applications especially if the properties come from the shell environment variables and can be set at will, or from the java -D option.
If anyone knows anything about this technique please respond to the present mail or to [email protected]
thank you,
Joe

Hi,
I have very similar requirement, In my scenario I need to pick up files from 4 static locations and based on the file name and pick up type(file/ftp) I can find out the destination's connectivity information from a Cross-Referencing table(Based on MS-SQL Database table- I can get this using look API) in this table we maintaining more than 100 destinations(host/user_name/password etc).
Now I need to set the connectivity information dynamically at runtime. I know this is not possible with Standard XI but does anyone thinks this is possible by any technical way using with XI.. Adapter Modules or Java Proxies?
This is very Critical to win the war with other middleware tools. Please let me know your thoughts and comments...
thanks,

Dynamic configuration for the application

I'm a newbie and trying to evaluate JSF. I took part in a project with struts framework and i could say i don't like struts cause of some limitation and i suspect that JSF has the same limitation. First of all, there are JSP pages. I can't use JSP pages/templates stored somewhere else except web application. I'd like to store my templates in the database. This will give me ability to add/change/remove jsp page without redeploying war-archive. Yes, i can use exploded war-archive and add JSP pages straight into file system, but i don't like this way. Next problem is the configuration file like struts-config (faces-config, whatever). I have to write down all my navigation logic and beans mapping to this file and it's really annoying me. This kind of project requires dynamic configuration for the all web application and i'd like to add/change/remove pages, beans, actions without restarting/reconfiguring webapp. Today, I looked thru documentation and source code and found that FactoryFinder class could use my own classes but i'm not sure it will be enough for the dynamic configuration for the beans. In any case, it's a huge problem with the templates.
Right now i'm thinking about 1(one) JSP with XML/XSLT rendered HTML content and JSF for event/action handling. I mean, i'll use XSLT to render dynamic content and JSF for dispatching events. In that case i have to render form tag names in the HTML as JSF engine (i'm not sure if it possible). If it will take a lot of time to do this i'll have to switch a home-grown framework.
So, i really need advices how to implement this sort of dynamic behavior in the web application.
regars,
anton

A lot of what you're seeing are genuine limitations, but happily, JSF is so pluggable that you can overcome them.
JSPs are problematic in exactly the way you describe - unless your app server has support for pulling JSPs out of a database, etc., you're SOL. JSF, however, lets you use something other than JSPs by replacing the ViewHandler. That's a fair bit of work, but it is doable.
For navigation logic, you'd replace the NavigationHandler. As long as you're willing to write the code that can pull navigation rules from an external source, life is good.
For managed beans, all you need to replace is the VariableResolver - again, if you can pull the rules from an external source, you have full control.
This is all far from easy - and it's a huge amount of work for one person - but I'd imagine these pieces will become available from various sources. A core goal of JSF 1.0 was making the framework as a whole pluggable so that others can innovate on top of the framework.

Dynamic configuration variable lifetime?

We are migrating from PI 7.1 to PI 731 and one of our applications uses dynamic configuration variable. It is a custom dynamic config variable saved in the first message (IDOC to PI BPM). We have asynch to synch scenario and send a synchronous message from BPM.
Once the response is received, the message is sent back from BPM (Second send step). During this message, we have a receiver determination (which uses the previously defined dynamic config variable). When I look at this message in sxmb_moni, I see no 'Dynamic Configuration ' and my receiver determination fails.. This used to work in PI 7.1 before and was curious if something was changed in PI 7.31?
I had noticed previously that dynamic configuration variable was removed when the logic went in exception processing of the BPM (even in PI 7.1).

As I had indicated, I was creating a custom dynamic configuration variable (with custom namespace and custom name). It was not a standard...
Essentially, a short cut to store the variable from input message (which will no longer be available in my response).

Is there a way to restart my Java cloud service? What are "non-dynamic configuration changes"?

I am trying to deploy an ADF application to my trial instance of Java cloud, I am getting the following error:
2013-10-15 08:24:18 CDT: Deploy Application started
2013-10-15 08:24:19 CDT: weblogic.management.DeploymentException: [Deployer:149189]An attempt was made to execute the 'deploy' operation on an application named 'xyzAPP' that is not currently available. The application may have been created after non-dynamic configuration changes were activated. If so, the operation can not be performed until server is restarted so that the application will be available.

There are tutorials available for deploying your first ADF app to the cloud, which I followed carefully. Except for one thing, the ADF app was originally developed in Jdeveloper 11.1.2.4 and then migrated to 11.1.1.6. Could that be what is causing the problem? How can I try to troubleshoot this?

Hi,
You will have to raise an sr towards the hosting team to perform the restart.

Dynamic Birthday List Application

Hello,
I have a requirement to develop a dynamic "Birthday List" application which will display the birthdays of all employees for that particular day.
I am planning to put a birthday excel sheet somewhere in the portal server and this application will fetch the information from the excel.
I have to incorporate this application in my WPC page so can't use webdynpro to develope this.
Any suggestion what is the best way to develop this application.
Any tool which is available which can be used for this purpose?
Our portal is NW 7.01 SP 06
Thanks
Deb

Dear Deb,
How are you.
You can create the custom Java application (i.e PAR) or webdynpro application and fetch the "Birthday List" from excel sheet in the custom applicatio and match with current date. Based matched data you can build the page to show in the SAP Portal.
If there is no data in the current date, then you can show "No Data Available" and If there is match data in the current date available, then you can show the associated page.
If you are using the PAR or Webdynpro iview, you can show in the WPC. For this you need to use the [Configuring Entry Points for iViews|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/06/4776399abf4b73945acb8fb4f41473/content.htm]
Hope it will helps.

Getting an error in Dynamic Configuration

Hi Guys,
I need to dynamically post the file into different directories based on the file in the source payload.
In Receiver File Communication Channel
Target Directory : *
Filename : *
Checked the ASMA Attributes for filename and directory
Iam refering this weblog
/people/william.li/blog/2006/04/18/dynamic-configuration-of-some-communication-channel-parameters-using-message-mapping
In the mapping
<filename> ---> UDF --> topnode of target message.
My UDF is as below
public String Directory(String a,Container container){
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
DynamicConfigurationKey key1 = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "Directory");
String FileName = conf.get(key);
FileName = a;
conf.put(key, FileName);
String Directory = conf.get(key1);
Directory = "/SAPInterface/XI/PPD/DHX/out";
conf.put(key1, Directory);
return " ";
But in runtime(moni) iam getting error as
com.sap.aii.af.ra.ms.api.MessagingException: The Adapter Message Property 'FileName' was configured as mandatory element, but there is no 'DynamicConfiguration' element in the XI Message header: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: The Adapter Message Property 'FileName' was configured as mandatory element, but there is no 'DynamicConfiguration' element in the XI Message header
Please suggest me how to correct this.
Thanks
Srinivas

Hi Srinivas,
You said you are having dynamic directories to post the file. But I see you hardcorded or put constant for directory which is /SAPInterface/XI/PPD/DHX/out. I think you need to put //SAPInterface/XI/PPD/DHX/out.
Try this in udf:
public String Directory(String a,Container container){
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
DynamicConfigurationKey key1 = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "Directory");
String FileName = conf.get(key);
FileName = a;
conf.put(key, FileName);
Directory = "//SAPInterface/XI/PPD/DHX/out";
conf.put(key1, Directory);
return " ";
Put FileName and Directory in file name and directory paramters in receiver communication cahnnel and cehck.

Two FileName in Dynamic Configuration

Hi All,
I have a very rare problem. In an interface which uses BPM, where file is the sender and Proxy is the target,
there is an ABAP Class in the mapping which uses Dyanmic Configuration to retrieve the FileName and create a Proxy structure and posts it to the ECC. In this scenario, Multiple files are picked from different folder using advanced Selection and sent to BPM which uses the ABAP Class.
When i run the interface with 5 different files placed at source, In SXMB_MONI, I can see that after 3 files are processed successfully with a single filename in the Dynamic Configuration, the 4th or the 5th one wil have 2 filenames in the dynamic configuration out of which the first filename will be the copy of the earlier processed filename and the second one wil be the actual required filename. The above behaviour keeps on chainging.
How can this be possible as the Context Object 'FileName' can have only single filename through out the interface instance, as there is no setting of the filename done in dynamic configuration.
Please reply if anyone has a solution to the above problem.
Thanks.

Hi Jaideep..
Thanks for the reply.
Yes.. its a serial processing. Let me explain a bit more.
as i said above, after the 3rd BPM instance (Just as an example.. keeps on chainging), the 4th instance has a unique filename compared to before 3. but after processing, the Dynamic Configuration in SXMB_MONI will have 2 fileNames. which will have a copy of any one of the earlier filenames along with actual filename.

Acces dynamic configuration variable (e.g. filename) in ABAP mapping class

Hi experts
I am searching for a possibility to acces a dynamic configuration variable (DCV) in an ABAP mapping class. Since I could not find a solution in SDN and other sources, I hope somebody in this forum can help me.
What I already found is the following code which can be used to set a DCV, but what I would be interested in is how to read a DCV.
Any help is appreciated.

Dynamic configuration required in sender file - Adapter Module

Hi Everybody,
I am developing an Adapter Module in the file adapter (sender) using Adapter Specific Message Attributes.
I am using Dynamic configuration inside the Module Process method in the adapter module.
We are getting an error saying Dynamic Configuration cannot be resolved.
Can anybody tell me the package to be used.
Thanks,
Zabiulla

You can access the dynamic configuration in adapter module like this:
Message msg = (Message) inputModuleData.getPrincipalData();
String fileName = msg.getMessageProperty("http://sap.com/xi/XI/System/File", "FileName");
You do not need any addition library besides the adapter module API.
Hope that helps

Dynamic Configuration File Names

Hi,
I have a RFC->XI->File scenario.
I have to put the target files names based on the calculation of values in 2 fields in the input.
I tried using Dynamic Configuration in my message mapping for this.
This is the code:
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create(u201Chttp://sap.com/xi/XI/System/Fileu201D,u201CFileNameu201D);
String MyFileName = a + "_" + b +".xml";
conf.put(key, myFileName);
I checked ASMA in both the sender RFC adapter as well as the receiver file adapter.
But it never works.
I saw the dynamic configuration tab in SXMB_MONI but i can see only the RFC destination parameter.
Cant see the file filename parameter.
What is the problem here?

No need enable ASMA on RFC sender adapter.
See if the file channel is activated after selecting ASMA with FileName.
The UDF might not be use in the mapping. Check this.
