Wait XML File Generation and Present in APEX

Hi All,
I need advice on how can I implement following -
I will be creating Input XML file using database procedure called from APEX, which will then go and executed the call using web services and create output XML file in one of the output directory. What I need help is -
1. Once execute the initial call, then I need to be keep looking for file under output directory. Once the file is generated then I can show it on APEX, but I would like to know how can I implement, so continuously watch the directory for the file and as soon as file generated pick that file and present on APEX and stop watching directory for file.
2. Also APEX will be used by many users concurrently, so how can I create and direct unique file for their own sessions, so myfile should not go to another user?
Please advice

There are lots of thread on ingesting XML and generating XML in this forum. Have a read through some of them and you should get some ideas on where to start. In particular look for threads on rcreating elational views of XML documents and using the SQL/XML Operators

Hi Keith
11g uses the EPG so the images are stored in the database, however are also accessible as a webfolder. This is the same as (or very similar to) XE which I've previously successfully installed this on. The files have been uploaded to the images directory as I'm able to reference /i/sample.html in the iframe successfully. I've never needed to change the .xml file and run apxldimg script, a simple copy and paste has always worked. However, I will try this just to make sure.
Hi Denes
I've tried putting in the absolute path of the directory, which I assume you mean the full path i.e. http://localhost:8080/images/charts_library. But this makes no difference. I know there are differences with 11g, the EPG and that you have to open http://localhost:8080/images/ as a web folder rather than http://localhost:8080/i/ to access the files in the images directory. However, the database that your example application on http://htmldb.oracle.com is running on is an 11g database. It's running 11.1.0.6.0 the same as my database, so it must be possible and by the fact you didn't know this I assume you didn't need to make any changes to make it work!

Error in XML file generation :240416

Hi All,
I am facing problem with XML file generation.
Steps:
1. Source-->Query Transform and maintained Nested Stucture

4. Make XML format as target and given XML generate path
source table-->Query(nested structure)-->XML Format
when I validate the job no errors found.
Note: XSD file is in Local mechine and XML file will be generated in SFTP.
Prooblems:
1. Getting below error
The input XML refers to file which is not part of the definition of this XML Schema format. Check your schema and XML files,
and check that the root element in the XML file corresponds to the root element in the XML Schema
Validate your XML Schema using external schema validators (found at w3.org)
Thanks,

Hi,
I think issue Because in your Query Transform output the Root element is Query and XML target is having some other root element. Make the Query trasform name similar to root element and try...

How to find PG.xml file name and path associated with a FUNCTION

Hi,
I am having a function:IRC_VIS_HOME_PAGE with Web HTML value as below:
OA.jsp?akRegionCode=IRC_VIS_HOME_PAGE&akRegionApplicationId=800&OAPB=IRC_BRAND
How to find PG.xml file name and path assoicated with above funtion.
Thanks,
ashok

Ashok,
Function IRC_VIS_HOME_PAGE will have 2 parameter defined for it which are OASF and OAHP where
OASF=<SelectedFunctionName> - this tells the Framework to select this function in the given "Home Page" menu context.
OAHP=<HomePageMenuName> - this is used ONLY with the OASF parameter, and it is used to establish the current menu context. It should point to a "Home Page" menu.

Regarding xml file sequence and sales order sequence not equal

Hi frnds,
                                 The XML File generates after sorting the line items, the sorting is done alphabetically on material master codes but the when the program converts the XML to Sales orders, the line item numbers does not matches with the line item of the XML File, like to understand how the XML conversion happens and is it possible to keep the same sequence of the XML file?

Could you pleas help me to solve this issue.
Thanks in advance.

Hello,
For processing XMLs always try to make use of the class CL_XML_DOCUMENT.
You can download the XML stream to a local file using the method of EXPORT_TO_FILE class CL_XML_DOCUMENT.

Basic doubt about XML file generation

Hi,
I am new to Java. I am facing some trouble designing and implementing a particular problem involving XML files.
Problem:
I have an XML file which contains a set of properties and their default value. What I need to do is to read another file/stream which will have name=value strings and then, for all the names that I find there, change default value to current value. These names can appear in any order. For example,
<name1 value=default1/>
<name2 value=default2/>
<name3 value=default3/>
And I will get something like "set name3=value3 name1=value1" (This data comes to me from a stream -usb device- and not from a file). Then I should change it to
<name1 value=value1/>
<name2 value=default2/>
<name3 value=value3/>
What is the best possible way to do this in Java? This has to go into an embedded system so it will be nice if it can be done with minimum memory and less processing power.
I am currently reading J2EEtutorial (1.4). I have not read much. But I am confused if I should be using SAX, DOM or XSLT. To speak the truth, I don't even know the difference between all those. Any help will be greatly appreciated.
Thanks & Regards,
Suseelan

Use a DOM parser to parse the original XML.
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder domBuilder = domFactory.newDocumentBuilder();
Document document = domBuilder.parse( inputStreamToFile );Then read in the contents from your USB stream into say an array or Vector. Then go through each child node in the domBuilder class, get the nodes name and see if it's in the Vector of objects from the USB stream. If it is, then replace the "Value" attribute in the dom node with what is in the Vector.
Make sense?

Web.xml file generation problem

Hi,
I am trying to create web.xml file automatically using "java weblogic.marathon.ddinit.WebInit
" command.
I got the following message in the command prompt:
Found Web components. Initializing descriptors
filters=0 servlets=0 tags=0
Above command is creating the web.xml and weblogic.xml files but it is not including
the servlet-mapping information. why?
Thanks,
Prakash

It doesn't look like it found any servlets. You'd have to show me your
files if I'm to understand what's going on.

XML file generation in Java

Hello,
I'm using XML files to communicate two systems. The XML files fulfill a W3C Schema.
I want to know if there is any Java library, API or something like this, to generate automatically XML files that fulfill a schema, giving the schema file and the data to fill the XML file.
Thanks,
Laura.

There may be several alternative ways, but maybe the simplest way around is using object views and spool the data coming -
CREATE TABLE warehouse_table (
WarehouseID NUMBER,
Area NUMBER,
Docks NUMBER,
DockType VARCHAR2(100),
WaterAccess VARCHAR2(10),
RailAccess VARCHAR2(10),
Parking VARCHAR2(20),
VClearance NUMBER );
INSERT INTO warehouse_table
VALUES(5, 103000,3,’Side Load’,'false’,'true’,'Lot’,15);
CREATE VIEW warehouse_view OF XMLTYPE
– XMLSCHEMA “http://www.oracle.com/xwarehouses.xsd”
– ELEMENT “Warehouse”
WITH OBJECT ID
(extract(OBJECT_VALUE, ‘/Warehouse/Area/text()’).getnumberval())
AS SELECT XMLELEMENT(”Warehouse”,

Datalink sequence method (XML file generation problem using Rdf)

Hi All
I want to Generate XML File using RDF , Here i used 4 datablocks and i lilnked each datablock with datalink like 1 to 2, 1to 3 and 1 to 4 respectively. while executing the report it choosing only one link like 1 to 2 and writting the data in the file for the same. its not touching 3rd and 4th datablocks I need to have data for all the blocks that are available.
One more thing i want to close each blockonce the data is written in the file.But in this case the tags get open wites data goes to the other block write the data for this block come back to the first block and closes the block.
eg: <Start>
<First block>
<Second block>
<Third Block>
</Third block>
</second block>
</First block>
</Start>
My requirment is
<start>
<First block>
</First block>
<Second block>
</Second block>
<Third Block>
</Third block>
</Start>

You might want to look at the SQL/XML operators XMLAGG, XMLELEMENT, XMLFOREST, XMLATTRIBUTES. They provide you with fine grained control over the XML generated.

How can I make an XML file print �, � and �

When I write an xml file by hand I can use the European alphabet and the letters �,� and �. I can also write to an ordinary text file from my Java code and still be able to display the letters as they should.
But when writing to an xml file in my Java code the letters are converted to some weird mishmash characters.
Why is this? What can I do?
// Elin

I'm assuming you are working on a Windows computer (although you can run into this on any computer.)
If you don't tell java the kind of character encoding you want, then you get an assumed desired character encoding - in Windows, the OEM characterset which does not include the characters you are trying to write.
A way to handle this is to output the kind of file you really want - that is - with the encoding you want. I suggest you might try UTF-8, which you can get by simply instantiating your output writer with the encoding string "UTF-8".

Compare two XML files: Analysis and Design

Hi, Java/XML/JDOM experts,
I realised that an open source of Java utility to compare two XML is still missing. So I would like to write one for my JDOM excises.
I plan to do it in three steps:
1.Define the problem domain.
2.Design the classes to be developed.
3.Coding
Below is the problem domain. Would you review it and tell me if it is fine?
Best regards,
AG
Compare two XML files
Schema assumption:
The xml files used for the comparison must have the same schema.
Definition:
1. Two elements of simple type are said equal if their name and value are identical.
2. Two elements of complex type are said comparable if their name, attributes are identical.
3. Two elements of complex type are said equal if they are comparable and their children elements are identical.

Hi,
Thanks for reviewing my idea.
The xml files used for the comparison must have the
same schema.Including not having a schema at all? And if they do
have a schema, must they be valid according to the
schema?I will only support schema based xml files. To include a schema is a good practice. So I will valid them agaisnt schema (is this possible with JDOM? I am testing ...)
>
2. Two elements of complex type are said comparableif
their name, attributes are identical.
3. Two elements of complex type are said equal ifthey
are comparable and their children elements are
identical.Do you plan to require child elements to appear in the
same order for the two documents to be equal? (Note
that XML specifically says that the order of
attributes is not significant.)No. The order is not significant as I use the attributes as the keys to find comparable element counterpart.
Here is the sample code already tested. Any comments are welcome!
The next step is to define the "delta xml schema" that will guide me to store the comparasion results. Do you have any suggestions?
Regards.
AG
public static boolean comparable(Element element1, Element element2)
     boolean returnValue=false;
     if (element1.getName()!=element2.getName()) {
          return returnValue;
} else {
          returnValue=true;
                    System.out.println ("place 2");
     List attributeList=element1.getAttributes();
     Iterator attributeIterator=attributeList.iterator();
     Attribute workingAttribute=null;
     while (attributeIterator.hasNext()) {
                         if (!workingAttribute.getValue().equals(
                         element2.getAttribute(workingAttribute.getName(), workingAttribute.getNamespace()).getValue()))

Automatic xml file generation

parsing xml file and then getting data from xml is ok but is there any api that support xml file generatoion from data itself
help plz

JDOM has an XMLOutputter.
DOM Level 3 allegedly supports outputting from the DOM itself.
However if you don't want to use JDOM, and you don't have access to DOM Level 3, there is a way to do it using transformers. I'm not sure if this is a trick or whether it's considered the standard way to do it.
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
Document dom; // this is what you want outputted
OutputStream stream; // this is where you want it outputted
Transformer identity = TransformerFactory.newInstance().newTransformer();
identity.transform(new DOMSource(dom), new StreamResult(stream));Note that it's not actually much code if you keep the identity transform around for reuse. JDOM's approach is a lot simpler though. :-)

Hi I am looking for a simple way of creating a xml file, populate it with data and saving it. Is there any simple way to achieve this ?

What API/language are you using?
If it's Cocoa look at NSXMLDocument
