Code sample to dequeue messages

I am looking for a code sample to dequeue messages from CRM OD? How do I retrieve the xml file after it is generated. Do I need to use a web service to retrieve that?
Preference would be to get the code snippet in java, but not necessary.
Thanks.

Hi,
I'm assuming you are referring to integration event messages? If so, then yes, you do need to use WS in order to retrieve them from CRMOD. Please refer to the CRM On Demand online help for Integration Events. It will provide details on downloading the WSDL file for Integration Events and the schema files which are required to process the events once they are retrieved. The WS User Guide contains details regarding the use of the GetEvents and DeleteEvents methods to retrieve and delete events from the queue.
Sorry, I don't currently have a code sample that I can provide.
Thanks,
Sean

Exception while dequeuing message

Hi,

Laura, I need some code samples you mentioned...

Laura,
I posted a message a few days ago regarding calling Stored Procedures in my JDev 3.1 (JDK 1.2.2) BC4J application. I need to be able to call them two different ways. The first involves passing some parameters to the SP and recieving back the ResultSet. In the other instance I simply need to make a call to them to perform some tasks on the DB side. Nothing will be returned from these SP's. You discussed implementing the SQL as a VO and gave me some code showing me how I might do this. You also mentioned that it is possible to create a method on the AppMod and call this from the JSP client. I need to know which method should work best for me and to get the code samples for the second option.
Thanks.
Rob

Hi,
Here is the code I used for the custom method on my VO (same could be used from the app module rather than a specific VO). The stored procedure I am calling here performs some calculations and returns an integer value:
public int getTotalHits(String mon, String year) {
CallableStatement stmt = null;
int total;
String totalhits = "{? = call walkthru.total_hits(?,?)}";
stmt = getDBTransaction().createCallableStatement(totalhits, 1);
try
// Bind the Statement Parameters and Execute this Statement
stmt.registerOutParameter(1,Types.INTEGER);
stmt.setString(2,mon);
stmt.setString(3,year);
stmt.execute();
total = stmt.getInt(1);
catch (Exception ex)
throw new oracle.jbo.JboException(ex);
finally
try
stmt.close();
catch (Exception nex)
return total;
After adding the custom method to your appmoduleImpl.java file and rebuilt your BC4J project, do the following:
1. Select the Application Module object and choose Edit from the context menu.
2. Click on the Client Methods page. You should see the method you added in the Available list.
3. Select the method and shuttle it to the Selected list.
4. Click Finish. You should see a new file generated under the application module object node in the Navigator named appmodule.java that contains the client stubs for your method.
5. Save and rebuild your BC4J project.
I wrote a custom web bean to use from my JSP page to call the method on my VO:
public class GetTotals extends oracle.jdeveloper.html.DataWebBeanImpl {
public void render() {
int totalhits;
try
Row[] rows;
// Retrieve all records by default, the qView variable is defined in the base class
qView.setRangeSize(-1);
qView.first();
rows = qView.getAllRowsInRange();
// instantiate a view object for our exported method
// and call the stored procedure to get the total
ViewObject vo = qView.getViewObject();
wtQueryView theView = (wtQueryView) vo;
totalhits = theView.getTotalHits(session.getValue("m").toString(),session.getValue("y").toString());
out.println(totalhits);
} catch(Exception ex)
throw new RuntimeException(ex.getMessage());
I just call the render method on this custom web bean from the JSP. I am not passing parameters to the render method of the bean, but instead access the parameters I need from the session:
session.getValue("m").toString()
I set these session parameters from the JSP that is called when the user submits their query criteria form. For example:
// get the view parameter from the form String month = request.getParameter("month");
String year = request.getParameter("year");
// store the information for reference later session.putValue("m", month); session.putValue("y", year);
Hope this helps.

Hello Raja,
Check to see if your internet access blocks ftp connections. This looks like a response that one gets when attempting to access an ftp site through a proxy server that will not allow ftp protocol. Many companies do this as a security measure.

Does listen get unblocked if there is uncommitted dequeued message

Here is the scenario.
I have 2 threads.
1 comes in; Does listen on a multi consumer queue. Gets a message and starts
processing.
At this point 2 comes in; Does the listen; At this point there are no new messages
on the queue. But thread 1 has not committed the dequeue. Will the listen wait
for the duration specified ? or will it return right away?
If it did return right away, then I cannot really do a listen until the thread 1 has committed.
What is expected behavior?
Thanks
Vijay

The answer to your question is I don't know because I would never enqueue or dequeue messages with default parameters. Not only is it a bad practice in that behavior can potentially change after upgrading or applying patches but doing so makes maintenance infinitely more difficult, as you are now discovering, because no one necessarily remembers for each version what the default behavior is.
When you want a specific behavior you code that specific behavior.
Read the docs on the following:
dbms_aq.dequeue_options_t
dbms_aq.enqueue_options_t
dbms_aq.message_properties_t
Then define the properties you want.
You can find some information about them here:
http://www.psoug.org/reference/dbms_aq.html

Is there a RH standard for formatting code samples?

In the RH default style sheet, I do not see a pre HTML tag or other tag that will display code samples in a monospaced font.
I created custom styles for a single line code sample and another style for multiline samples.
We want our code samples to be shaded. If I shade multiple lines, each line being separated with a paragraph, there is a small amount of
white space between each line. We do not like this either.
I then created a custom table style with a single shaded cell. I add my multiline sample code, then I apply the custom paragraph style to get
the font and spacing between lines that I want.
Is there a different best practice for this, so that the code sample would be rendered correctly if viewed from other devices that read the HTML and
may look for the pre HTML tag?
I am using RoboHelp 9 and I provide the output as Eclipse help. Our help files are integrated into Eclipse help in the Eclipse IDE.
Thank you.
Cynthia

Hi Cynthia
As much as it pains me to say it, this is one case where using a Form element might be your best bet. I say this because often code samples are used or presented with the intent of copying and pasting into something like Windows Notepad. And if you used the TextArea form element, you can place the code there and make it pretty easy for folks to copy it for use elsewhere.
I stand to be corrected on this because I am not a "power CSS" person. (meaning I am aware there are complete two and three day classes one might attend on all the nuances of CSS) But RoboHelp won't really do anything to help you a great deal in formatting things. But it might be possible, somehow, to configure CSS to accomplish your goal of making the code look as you want.
Cheers... Rick

Dequeuing messages not working

I am trying to dequeue messages through the use of a java durable subscriber. That is the only subscriber. I successfully get the message and then call the method _session.commit();. Neither throw any errors and I am confused as to why the queue shows the message as processed yet it is still in the queue. Is there an orcale process that needs to be running to remove these dequeued messages? Propagation between databases is not a valid solution. So, some of the examples do not hold for my current setup.
my setup:
oracle 9i
create table, schema, objects, trigger to push jms messages into queue
java client to dequeue messages.
One strange thing I notice, at least to me, is that in order for the trigger to place messages into the queue, i need to either start the java durable subscriber up so it creates a subscriber or run the following: EXECUTE create_subs ( "name", "queue_name", null, null );. Now do I now have two subscribers once I start the java client up after running the PL/SQL command?
per my requirements I need to be able to queue things through a trigger, thus I need to be able to queue messages without having a java durable subscriber running.
Is there a way to determine who is subscribed? For some reason I am not seeing the information i need in any document or on any list.
Any help would be greatly appreciated.
Thanks,
James

createDurableSubscriber creates a new subscriber or gets an handle to an existing subscriber.
When you enqueue a message - you must either have created the subscriber or explicitly specified the recipient during the publish. From what you are seeing it seems that you are trying to enqueue a message without creating the subscriber.
If you want to do this then you must explicilty specify the recipient in the publish call. You'll need to use OJMS extensions in AQjmsSession to do this. The recipients can be specified as an array of AQjmsAgent s

Recently can't play music samples on Amazon France (and Germany, though they've now gone over to Flash, which seems to have fixed it after (re)installing Flash Player) via their usual 'Listen to all' button. Can only play samples individually. Message says roughly RealPlayer not installed on my navigator (see box below), but I've changed nothing and have always had RealPlayer on my PC at least.

Hello Neil.
It has been reported by other uses that RealPlayer is having some compatibility problems with Firefox. I believe this is mostly notorious with RealPlayer Plugin Record Plugin, but it may be the same thing here. Please contact RealPlayer developers for support.
