Documention for creating portlets using pl/sql???

Hi,
can anyone help me get links for any kind of documentation about creating portlets using pl/sql for Oracle Application Server Portal 10g
thanks
M

I think this will help out...
Check out Chapter 8, "Creating PL/SQL Portlets" in the Oracle Portal 10.1.4 Developer's Guide.

Documentation for creating midi device plugin bundle?

I've got a custom MIDI controller (vmeter), and wanted to know if there was any documentation for creating a plugin bundle file to make Logic Pro integration easier? The documentation says plug-ins can be added to the Logic Pro Applicaiton folder / Contents/MIDI Device Plugins subfolder. Any advice on how to make those .bundle files?

Depending on the format of your "templates", you could go with any of the options – Plugin, IAC or JavaScript.
Plugins give you the most power, but as you note, have to be written in C/C++ using Visual Studio. For Acrobat X, you need VS2008. You should be able to compile the sample plugins in the SDK – just be sure to follow the instructions/docs about where to put the SDK folders. OR consider installing the using the Plugin Wizard that is in the Tools directory which will help you create new projects.
IAC or JavaScript. There isn't anything in IAC proper that will help you and you don't want to use the ActiveX control, you want to use the COM APIs. Again, try the included samples for C# or VB.
HOWEVER, what you can do it is call the JavaScript APIs (there is one for adding a watermark which you'll use) from your .NET application. See the docs about the JSObject.

JMS/AQ: Setting properties for JMS message using PL/SQL

I have created a procedure in PL/SQL that uses JMS messages, and now I need to include a property so that the subscriber can use a message selector to filter out unwanted messages. Is this possible using PL/SQL?
A previous post said: "... But you can have properties in the message payload itself and also define selectors on the message content ...". But I looked at Sun's tutorial and there it said: "A message selector cannot select messages on the basis of the content of the message body."
I have 300 different screens and messages apply only to one screen at a time. When the user is looking at screen 'A' I want him to only recieve messages that apply to screen 'A'. I thought I would do this with message selector, but is there any other way?
Here is my code(borrowed from an earlier post)
PROCEDURE ENQUEUE_JMS_MESSAGE AS
BEGIN
DECLARE
Enqueue_options DBMS_AQ.enqueue_options_t;
Message_properties DBMS_AQ.message_properties_t;
Message_handle RAW(16);
User_prop_array SYS.AQ$_JMS_USERPROPARRAY;
Agent SYS.AQ$_AGENT;
Header SYS.AQ$_JMS_HEADER;
Message SYS.AQ$_JMS_TEXT_MESSAGE;
Message_text VARCHAR2(100);
BEGIN
Agent := SYS.AQ$_AGENT('',NULL,0);
User_prop_array := SYS.AQ$_JMS_USERPROPARRAY();
Header := SYS.AQ$_JMS_HEADER( Agent, '', 'aq1', '', '', '', User_prop_array);
Message_text := 'Message 1 from PL/SQL';
Message := SYS.AQ$_JMS_TEXT_MESSAGE(Header, LENGTH(Message_text), Message_text, NULL);
DBMS_AQ.ENQUEUE(queue_name => 'tstopic',
Enqueue_options => enqueue_options,
Message_properties => message_properties,
Payload => message,
Msgid => message_handle);
END;
END;
-Christer

Thanks for the answer. I managed to set the Correlation id and retrieve it using getJMSCorrelationID(). But I did not manage to use the MessageSelector on it. I have used the Topicbrowser which is not part of the JMS standard? I tried to enqueue the messages using Java too and tried to use the topicbrowser on both JMSCorrelationID and user defined properties withou success. Is there some special requirements of the TopicBrowser?
Enumeration messages;
oracle.jms.TopicBrowser browser =tsess.createBrowser(topic, "TS", "JMSCorrelationID = 'TST'");
int count = 0;
messages = browser.getEnumeration();
if(messages.hasMoreElements())
System.out.println("message"); //never executed
dtxtmsg = (TextMessage)(tsub1.receiveNoWait()) ; //returns a message
String corrID = dtxtmsg.getJMSCorrelationID(); //returns: TST
Thanks for your help so far...it would really save my day if you have some ideas on this too!

Creating Repositories using MS SQL Server DataBase in Data Service Reposito

HI All,
I installed BODS and I am trying to create repository using Data Service Repository Manager but I am getting the following error message :
Cannot open connection to the repository. The error message from the underlying DBMS is <ODBC call <SQLDriverConnect> for data source <localhost> failed: <[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.>. Notify Customer Support.>. (BODI-20006)
An error occurred during creation of the local repository. (BODI-300054)
While installing BODS i used the option to create DB .... Before that even I had Microsoft SQL server installed for MDM which was working fine (Able to Log on and so on)...
Do I need to install Oracle in order to create repositories? How to proceed further please suggest.
many Thanks
Rajeev.

Hi!
What version of SQL Server are you using for the repositories? Maybe the error is because DS can not create repositories in SQL Server 2008. You can read and write data with SQL2008, but you need to create the repositories in SQL2005 or another RDBMS. I'm not sure when DS is going to be able to create them in SQL2008.
I hope this could help you. Greetings!
See you

Best Practices for creating PDFs using PLPDF?

Does anyone have any suggestions for Best Practices in making PDF files using PLPDF?
I have been using it for about a month now, and the best that I have come up with is to use MS Access to prototype the layout of a report. Once I have all the graphics areas and text areas lined up how I would want them, I then write PLSQL code to create a procedure which is called from an HTMLDB page. MS Access is handy in that it provides the XY coordinates for each text area and graphics area. It also provides the dimensions of the respective cells. So long as I call plpdf.Init('P', 'in', 'letter') at the beginning of the procedure, both my MS Access prototype and my plpdf code are both using inches - this makes the translation relatively easy.
Has anybody found anything else easier/better?
Regards,

You can make it happen by creating a private connection for 40 users by capi script and when creating portlet select 2nd option in Users Logged in section. In this the portlet uses there own private connection every time user logs in.
So that it won't ask for password.
Another thing is there is an option of entering password or not in ASC in discoverer section, if your version 10.1.2.2. Let me know if you need more information

Creating Files Using PL/SQL?

Hi,
Is there a way to create a file using PL/Sql? It seems that the
utl_file package doesn't allow you to create a file. It only
allows you to read, write to a file that already exists there.
Thanks
Vic

Make sure the following is set in the init.ora:
UTL_FILE_DIR = /path/to/your/file/directory (for unix)
or
UTL_FILE_DIR = <drive>:\path\to\your\file\directory (for windows)

Need Ideas for creating and using Custom Business Object

Hello Guys,
I am developing an application which uses a Request->Approve->Create approach for creating Purchase documents.
Now I am a little puzzled about how to make use of the Business Object BUS2014.
The application I am developing has its own unique 'Request Number' (say REQID) which will point to the Request for Creation of a purchase order.
Whenever a Request is created (from a Z-Tcode) a workflow needs to be initiated and it has to be sent to the approver.
The Purchase Document will be created once the approver approves.
Now my confusion here is, if I use BUS2014, the object will be instantiated only during the final step of the workflow. But I need an instance during the beginning of the Requestor ->Approver negotiations as I am playing with events. These events needs an Object_key.
How should I proceed here?
Should I create a new logical Business Object like ZPOREQ where I have the above mentioned REQID as the key?
And should I have an attribute of type BUS2014 inside the custom BO?
How will I make use of the methods like BUS2014.Create etc which I may need to create the purchase document?
Any small direction will be a huge help for me to get used to this wilderness.

Hi,
You should continue with the ABAP class idea. The business objects are kind of "obsolete" already, and if there is a need to create a new "object", ABAP classes are the way to go. Business objects are still useful, but I normally use them only when an existing standard business object fulfills the requirements (possibly with slight additions) which is almost never.
From my point of view you can use the existing class. Depending on the circumstances I normally have just one class that I use for both workflow and the possible other functionality that is required, but you have to understand that I have this goal in my mind already when starting the development process. As your class most probably has many useful features already (such as you have the header and item data as attributes etc. (if I understood correctly?), these are also useful in in workflow (class attributes will be available in WF container etc.).
If you are hesitant to use the same class directly in your workflow, you could also create a new class ZCL_REQUEST_FOR_WF (with the workflow interface), and then simply add your existing class ZCL_WF_REQUEST as an attribute to this new class. Then this new workflow class could include the pure workflow stuff, and your existing class the non-workflow stuff. But this most probably will not make much sense - just implement the if_workflow interface in your existing class (this is just one possibility that you might consider.)

Karri

Mainframe data loaded into Oracle tables - Test for low values using PL/SQL

Mainframe legacy data has been copied straight from the legacy tables into mirrored tables in Oracle. Some columns from the mainframe data had 'low values' in them. These columns were defined on the Oracle tables as varchar2 types. In looking at the data, some of these columns appear to have data that looks like little square boxes, not sure but maybe that is the way Oracle interprets the 'low values' in the original data into varchar. When I run a select to find all rows where this column is not null, it selects these columns. In the results of the select statement, the columns appear to be blank, however, in looking at the data in the column using SQL Developer, I can see the odd 'square boxes'. My guess is that the select statement is detecting that something exists in this column. Long story short, some how I am going to have to test this legacy data on the Oracle table using Pl/Sql to test for 'low values'. Does anyone have any suggestions on how I could do this????? Help! The mainframe data we are loading into these tables is loaded with columns with low values.
I am using Oracle 11i.
Thanks

Need help on creating portlets using JSR268.

Hi All,
I want some details about how to create portlets with JSR 268 statndards.
I am creating portlets with address and location viewer using google maps service.
how to pass address parameters to the map portlet ?
thanks
Gopi

If you want to pass parameters from one portlet to another, you should use parameters. I am currently working on a blog post that shows these features. I'm hoping to have it finished by the end of the day...
Meanwhile i can tell you that you need to create parameters in the portlet.xml as shown in this image: https://picasaweb.google.com/yannick.ongena/IPC#5636361095514333538
Then you need to tell assign that parameter to the portlet as shown here: https://picasaweb.google.com/yannick.ongena/IPC#5636361093578581890
A thirth thing to do is set the value of the parameter. In your locations portlet you should write following code to set the parameter:
PortletRequest req = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
req.setParameter("nameOfParameter",value); In your maps portlet you can read the value of the parameter with following code:
PortletRequest req = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
String param = (String)req.getParameter("nameOfParameter");
if(param == null)
return "someDefaultValue";
return param;You might need to set a partialTrigger on the maps portlet that points to the location portlets. That's it.

Portal API's to display "page published as a portlet" using pl/sql

I have a custom pl/sql portlet that we have developed. We want to programatically display the contents of another portlet which is a "portal page published as a portlet". I know when you have a provider portlet you can simply call it like this:
portal.provider_name.show();
But how do you display a page published as a portlet using portal API's?

Nobody has a clue?

Dynamically create javascripts using pl/sql code from page header

I understand by placing a javascript code in the page header is one of the way adding javascript functionality to your pages.
But lets say I need (dynamically) bring my javascripts into the page header using my pl/sql package/functions like core_func_jscript_pkg.get_jscript('jf_isnumber');
1- How can I call my pl/sql package/functions from page header area of Apex?
If I need to use 20 javascripts functions into a page which I have them stored in database (using them on my other pages) and I don't want to copy or re-write them in Apex, instead I like to have 20 line of calls to my pl/sql package like:
core_func_jscript_pkg.get_jscript('myFirstJavascript');
core_func_jscript_pkg.get_jscript('mySecondJavascript');
core_func_jscript_pkg.get_jscript('myThirdJavascript');
core_func_jscript_pkg.get_jscript('myFourthJavascript');
... and so on.
2- In past we wrote our web apps using pl/sql example:
htp.p('<html>');
htp.p('<head>');
core_func_jscript_pkg.get_jscript('jf_get_today_date');
core_func_jscript_pkg.get_jscript('someothe_scripts');
htp.p('</head>');
htp.p('</html>');
I like to do the same thing in Apex, Can I accomplish this in Apex?
Thanks again
