How to call a SQL function from an XSL expression

Hi
In R12, in Payroll Deposit adivce/Check writer, We need to sort the earnings tag <AC_Earnings> in to two different categories as regular and other earnings. In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :

How to call a jsp page from oaf and run in jDeveloper

Re: how to call a jsp page from oaf
Please help me to do this.
Thanks in advance.
Regards,

Raj,
1. Hope you have placed the custom jsp page (which you have downloaded from server) under "jdevhome\jdev\myhtml\OA_HTML" directory ?
2. Try to run the custom jsp page from Jdeveloper directly and check whether its working properly or not ?
(i.e. add jsp page to any project in Jdeveloper then right click on jsp page and select Run xxx.jsp)
3. If page errors out then custom jsp page seems require few parameters to run it successfully. Pass all requied parameters and test.
4. There is no problem in the way you are calling jsp page from OAF page.
regards,
Anand

Hi,
You are running a jsp report through rwservlet. In this case paper layout will be displayed. You have to deploy your jsp as web report to get the web layout. Please refer to the doc below, which describes how to deploy the web report.
http://download-uk.oracle.com/docs/html/B10314_01/pbr_run.htm#1011901
To run the jsp report, URL may look like
http://www.wwt.com/reports/<jsp name>?<parameter list>
Hope this helps

How to call a php function from java...

helllo fellow java developers!
Im trying to figure out how I can call a php function from my java code.
I know it sounds a bit unintiutive, seeing how java is a rich programming language, BUT java simply cannot do the task that the php script can do. It simply acts differently.
So I am trying to call a php function, that returns a string object, and capture that string object....
is this possible?
something like....
String strMyString = phpFunction( strVariable )
???????/ any ideaS?

idea #1 - come up with a better plan that doesn't involve invoking php from java.
Give one example of something php can do that java can't.
idea #2 - forget java, and just write it in php.
Involving multiple frameworks/languages/runtime environments is a recipe for an overcomplicated solution that will be impossible to maintain.
I'd say keep it simple and stupid, and stick with one language.
If you're still hooked on the idea, maybe try [this link|http://www.infoq.com/news/2007/10/php-java-stack]

How to call two RFC in a single JAVA method.

Dear all,
I just want to know that how to call two RFC in a single java method which is defined in CRM implementation file. I'm using NWDS as the customization IDE & working on ISA 7.0.

Hi Sunil,
In the Backend Implementation class, in any method you can call multiple RFCs.
It will be the same way as you do for the single RFC call.
Following syntax is for your reference.
Get the JCO connection
JCoConnection connection = getDefaultJCoConnection();
JCO.Function func = connection.getJCoFunction("ZXXXXXXX");
set the import parameters
Execute it.
connection.execute(func);
get the data from export / table parameters
Now call the second RFC
func = connection.getJCoFunction("ZYYYYYYYYYY");
set the import parameters
Execute it.
get the data from export / table parameters
close the connection
Hope this will help you.
-Chandra.

How to execute a jsp instruction from a java class?

How to execute a jsp instruction from a java class?
Any help please.
Thank's

I'll detail my problem:
Supposing that I have a jsp file called: start.jsp
In the start.jsp I instanciated an object called global from the class Global ( for example ).
Then, I called a custom taglib:
<ix:mytag/>
In the suitable tld file: the mytag is defined:
<tag>
<tag class>Tag1<.....
The java file Tag1 has method:
doStartTag(){
// here is the problem
global.doSomeFunctions();
Okay, the problem is that the object gobal is not defined in the class Tag1. what to do?
I think that I have to pass the object global as a parameter to the class Tag1. How to do that?
Actually, the problem was to insert the follwoing in the doStartTag method:
doStartTag(){
pageContext.getOut().print("<%= hello world %>");
The output is <%= hello world %> not hello world.
Okay, the new problem is how to pass an object as a parameter to a class called from a tld file.
Any help please.
Thank's too much

How to call a html file in a java file

how to call a html file inside a java file ?

Hopeless. Are you by any chance a rare gas? You seem completely inert. LOL You totally pwned him there :rolls eyes:
well, no, I think he's looking for something to this degree:
in HTML, there is a mailto: command that makes the system default handled way to email emails open up. He's looking for a command thats very nice and opens a html file in the system default browser.
So, Dick, Runtime.exec would work execpt that he needs a way to find the default system browser to call exec on, AND he has to know how to pass html file locations to the executable via command line arguments
He just didnt try to phrase it at all :P
