Java Subscription Function

I created a custom java subscription function to be called from a business event and it worked fine the first time but when I started to add lines of code to it, those new lines are not being executed. I even tried deleting the class file and it was still executing the old code. It looks like the java class is being loaded in a jvm. Can you guys point me to the jvm that handles the java subscription function? What process do I need to restart to flush the jvm. If it is something else other than the jvm, what do i need to restart for the new class to take effect? Any documentation on the architecture will be helpful as well.

You are attempting to use Business Event system to get a status back to the calling program (in your case Product Workbench). Please note that your calling transaction (Product Workbench transaction) and the Business Event subscription's transaction are different.
Once you raise the business event, the BES sets a savepoint before executing the subscription and rolls back to that subscription when you raise the BusinessEventException. So the subscription transaction is rolledback but the exception is not really raised back to the Product Workbench.
If you are on Oracle Applications 12.0 you have a workaround though. The BusinessEvent class provides a new method called getResponseData. So you may pass a status back to the calling program by setting the response data of BusinessEvent object and from Product Worbench, call getResponseData and decide whether to continue or rollback the transaction.
Thanks

How to get the value retruned by java script function into my jsp page

Hai all,
I had a particular java script function which returns a date.
function getDate() {
var sDate;
// This code executes when the user clicks on a day in the calendar.
if ("TD" == event.srcElement.tagName)
// Test whether day is valid.
if ("" != event.srcElement.innerText)
//alert(event.srcElement.innerText);
sDate = document.all.year.value + "-" + document.all.month.value + "-" + event.srcElement.innerText;
document.all.ret.value = sDate;
var mahi=window.open("configurexml.jsp?xyz=document.all.ret.value")
return sDate;}
Now i want to display this particular date in my jsp page. can anyone tell me the correct approach or a sample code to diaplay this date in my jsp page.

Here where i am printing the date i had to get the value from the js function. how to do that. plz help me....

Are you talking about server-side java code (servlets/jsp) or client side (applet)? Given we are in the JSP forum I'll assume we're talking server side.
If so, you are making a common but fundamental mistake. JavaScript executes on the client, not on the server. If you want client data on the server it has to get there somehow. The simplest way to do this in JSP land is via HTTP. So... have your JavaScript code call a JSP (or servlet) and pass the value you want as a URL parameter. Of course this will also change the browser location, so if you don't want this to happen use a frame or iframe to capture your HTTP request.
For example:
Javascript....
function someFunction() {
return 1;
var value = someFunction();
location.href="somejsp.jsp?value=" + value;

How to set the classpath and path from the jsp to call java class function

Hi Exprets,
I have a requirement to call a java class function which returns a hashmap object from the jsp. The java class in present in one jar file and that jar file is location somewhere in unix path. So the requirement is to set the classpath for that jar file and then create the object of the java class and then call the function.
If any one know how to achieve it, please reply as soon as possible.
thanks in advance,

It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.

Wrong value in java stored function

Hi All,
i have written a java stored function,
at the end of the code it insert record into the database
among other columns also a number(18,3) column,
when I debug it (out side of server) - works fine.
when I load it to database i get wrong values in column
(like instead of 76.546 i get 77.667) I can't figure out where it comes from.
I use big decimal in java code.
if i Hard code the value in java code it works fine!
am I missing something ?, calculations/ data type different out side then inside database? using oracle 10.2.0.2
Cheers
Sahar

Hi
the code calculate some averages of amounts ( money) according to several
conditions,and parameters given to the function and stores the average into table in the database
the money columns are of data type 18,3 , both source and target tables have same structure.
thanks

Why returning string from java stored function failed ? HELP ME, PLEASE

Hi everybody,
I created java stored function: it's doing http post, parsing xml from http reply, and returning string result.
Sometimes, it doesn't return any value. What can be a reason ?
The high level procedure, has following form:
class SBE {
public static String call(String arg0) {
SBE sbe=new SBE("d:\\oracle\\ora81\\network\\log\\SBE.log");
String result=SBEParser.go(sbe.sendRequest(arg0, ""), sbe.logger);
sbe.logger.log(result);
sbe.logger.log("Finish SBE intetraction");
return result;
PLSQL wrapper has a simple form:
create or replace package PG_SBE as
function CALL(arg0 in varchar2) return varchar2;
end;
create or replace package body PG_SBE as
function CALL(arg0 varchar2) return varchar2 as language java name 'SBE.call(java.lang.String) return java.lang.String';
end;
In log file ("d:\\oracle\\ora81\\network\\log\\SBE.log"), I can find message :
"Finish SBE intetraction"
but query:
select pg_sbe.call("any argument") from dual;
doesn't finish.
What can be a reason ? What can I do to trace stage of convertion java string to varchar ?
Please help me...
Best regards
Marek

hi Stefan thanx.....even after changing the call statement i get the same error. i changed query string as...

This comes up periodically. It just isn't possible using that type of approach. Probably the best you could do is the create an ADT (containing collections) and use that to pass a 'batch' of information.
Hopefully this will get addressed in the next release of the database.

Recursing through table / complex return types in Java Stored Functions

I have a table representing a tree with arbitrary depth, of the form:
ID NUMBER(10) PRIMARY KEY,
NAME VARCHAR2(20),
PARENT NUMBER(10)
with PARENT being a foreign key for ID, so that top-level nodes in the tree have a NULL PARENT, and other nodes have the ID of their parent node in the PARENT field.
I want a good way to get a row representing a node as well as all its ancestor nodes recursively up to the top level. I do this a lot in my Java application, and right now it works by just getting each row, checking if PARENT is null, and recursing again until I get the top-level node. Since this recursion is in Java and I do multiple queries it's rather slow, and I'd rather perform this operation in the database (using a Java Stored Function/Procedure or PL/SQL).
I'm no good at PL/SQL so don't have a clue how to go about doing this sort of thing, and although I can write a Java Stored Function that does the same recursion I do in the application, I don't know how to return the results. I can't return a REF CURSOR type since the results are from multiple queries, and I can't find any documentation about how to return structured types from a JSF.
If anyone could give me a near-complete PL/SQL listing that does this or (better) help me to complete my Java Stored Function by returning the results in a structured type.

You are my own personal God (for the day). Thanks, exactly what I needed, and all in one query with no procedural.

Calling Java function from java script function

Hello,
I have a jsp in which on button click i am calling a java script function. now there is some data that i want to insert in a table on click of the same button. But in order to do that i need to write java code. but if i write java code inside the script function that is called on button click it doesnt work. what i understand is that i need to make a java function inside the jsp & call that from the script function. can someone tell me how to do that ?
this is the code i have written

Logging in java defined functions

Hi,
Are there any means of logging in java defined functions used in mapping?
Regards

Hi,
You can do MapTrace in the UD
MappingTrace trace = container.getTrace();
trace.addInfo("trace Text");
Thanks,

Customized java date function in heart of JDK

hi
how can i force JDK to return Persian or Arabic date instead of christian era?
i have an application in java platform. i couldn't change code of program, because source is closed and is not reachable. i want to know how can i use a wrapper for date function in java? if it is possible how can i replace java date functionality with my desired date function?
thanks for any help

Thanks for your help.
however i looking for one thing, similar a function wrapper that can substitute original method.
I don't know where the application use date function and how calls it. so i think that it is possible to change behavior of java itself.

Using the JAVA ImportXmlTemplate function, should I always use XSL directory?

Using the JAVA ImportXmlTemplate function requires XSL directory, I do not need XSL for my updates, how can I workaround this requirement?

Ok, thanks for your quick answer. I saw you last blog posting regarding simple bar codes, I hope your next one turns up soon (read: today ;-) ).
I did take a swing at writing my own class according to the user guide, using JDeveloper. One of my problems is that I am not that familiar with the whole java world, my experience lies almost entirely within .NET development. So when I read stuff like "make sure the class is available in the classpath for the JVM" and things like that, it is not a detailed enough description for me in order to make anything out of it. Do you think you can clarify that for me?
I also wonder if you have any tips and tricks on how to trace/log information from the class when it executes? Because I think that I can actually get it to be called, it's just that something goes wrong and the generated PDF becomes badly formatted and has no content. I can see that some calls are made to a Logger class inside the example class. I guess that I need to set up some runtime configuration for that information to turn up in a file, but again me lacking experience from the java world prevents me from accomplishing that :-)
Regarding tracing and logging from the java classes for the BI Publisher, can I get them to trace or log debug information in some clever way?
The app I am developing is a .NET app that calls these classes using a product called juggerNET. I am developing a print direct application for JDEdwards EnterpriseOne since BI Publisher is not entirely integrated into it yet.
I would greatly appreciate a quick reply this time as well if you can find the time!
Best regards, Jörgen

Why is there a java enable function in the settings app if java ia not supported by ipad2?

Why is there a java enable function in the settings app of the ipad2, ios5, when java is not supported by ios5 on the ipad2? The adds say that java neo, I think that is what it is supposed to be called, was supposedly introduced into the ios5 format to deal with this?

If you're looking in the settings for Safari, that's JavaScript, which despite the similarity in names is completely different from Java. Java is not, never has been, and all indications are never will be supported in iOS. I have no idea what "java neo" might be, but I've never seen Java mentioned in any way in any of Apple's iPad ads.
Regards.
