How to validate XML at runtime and show the exact cause of validation failure .

Hi
How can I validate my generated XML at runtine against its schema ? I have used
the validate() method and it does validate correctly against the schema but the
problem is it just returns a boolean . I need to know the exact cause of failure
(like for example The element X was supposed to contain Y,Z etc ). I need to capture
the exact exception (like a Sax Parse exception details).
How do i do that using XMLBeans ??

Hi Bana,
You could use the XmlOptions.setErrorListener(Collection) method to get the detailed error message by invoking validate(option).
Kind Regards,
Jennifer

Help: How to Validate XML using SAXParser and return the entire error list

Hi,
I have a problem, I'm trying to validate a xml document against the DTD. Here Im using SAXParser and having the ErrorHandler object passed when setting the error Handler, like parser.setErrorHandler(errorHandlerObj).
I need an output like where the entire XML document is read and all the errors have to be reported with the line number.
like example:
<b>Line 6: <promp>
[Error]:Element type "promp" must be declared.
Line 8: </prompt>
[Fatal Error]:The end-tag for element type "promp" must end with a '>' delimiter.
who can i achieve this.</b>
what happens with the present code is that it throws the first error it encountered and comes out.
how can i solve this problem

You can try to set the following feature to 'true' for your SAXParser:
http://apache.org/xml/features/continue-after-fatal-error
At least Xerces supports this feature.

How to validate XML against XSD and parse/save in one step using SAXParser?

How to validate XML against XSD and parse/save in one step using SAXParser?
I currently have an XML file and XSD. The XML file specifies the location of the XSD. In Java code I create a SAXParser with parameters indicating that it needs to validate the XML. However, SAXParser.parse does not validate the XML, but it does call my handler functions which save the elements/attributes in memory as it is read. On the other hand, XMLReader.parse does validate the XML against the XSD, but does not save the document in memory.
My code can call XMLReader.parse to validate the XML followed by SAXParser.parse to save the XML document in memory. But this sound inefficient. Besides, while a valid document is being parsed by XMLReader, it can be changed to be invalid and saved, and XMLReader.parse would be looking at the original file and would think that the file is OK, and then SAXParser.parse would parse the document without errors.

Have you looked at the XML DB FAQ thread (second post) in this forum? It has some examples for validating XML against schemas.

How to capture PLSQL package error and show the same in OAF Page.?

Hi all,
I am having the requirement to capture the error from a PL/SQL package and show the error in OAF page with meaning full error.
Assume i am having the create and review page.
The create page having the employeeLOV input field (non mandatory field).
(i have the package which will check whether this LOV value is filled or not.. if not given then the user should be able to see a "understandable message.)
to achieve the above scenario am following the below steps
In my CO,
with in try catch i called the am method which will invoke the XX_CUSTOM_PKG.
so, from the catch it is giving me the message as shown below.
try
((OAApplicationModule)localObject1).invokeMethod("insertData", personParam);--which will call the am method which in turn call the package.
catch(Exception exception)
throw new OAException("Review Error: "+ exception);
Assume there are 2 possiblity of error inside this package one for Date field and another one for Employee field. we don't know which validation the user will encounter.
For Employee field validation it is giving messag as below
Review Error: oracle.apps.fnd.framework.OAException: Exception in insertData:java.sql.SQLException: ORA-20500: Employee field is required. ORA-06512: at "APPS.CUSTOM_UTIL_PKG", line 702 ORA-06512: at line 1
for Date field as below.
Review Error: oracle.apps.fnd.framework.OAException: Exception in insertData:java.sql.SQLException: ORA-20500: Date field should always greater than sysdate. ORA-06512: at "APPS.CUSTOM_UTIL_PKG", line 702 ORA-06512: at line 1
But i need to display only the message "Employee field is required" or "Date field should always greater than sysdate" in the screen.. as information.
Could you please help me to achive the above message? any sample code will be great help for me.
Thanks,
Thiru.

try
((OAApplicationModule)localObject1).invokeMethod("insertData", personParam);--which will call the am method which in turn call the package.
catch(Exception exception)
//throw new OAException("Review Error: "+ exception);
/*Try this code*/
String exception = null;
exception = exception.toString();
if(exception.contains("Employee")){
throw new OAException("Employee field is required");
else if(exception.contains("Date")){
throw new OAException("Date field should always greater than sysdate");
else
throw new OAException(exception.toString());

How can I open a vi and show the block diagram?

Hi,
I am opening an vi using "Open VI Reference" and "Invoke Methodpen FP", but I want to open the vi and show the block diagram, but I haven´t found any method (Invoke Method) to do that and any property.
Any idea?
Thanks!
Gracinda

OK, I can come up with a reason. I have written a program that will search the entire VI Hierarchy of a program and update all of the descriptions for all VIs with the top level program part #, the name of the top level program that the VI is used in, the company copyright info, the ITAR notice, company address, the name of the engineer performing the update, along with the date and time. This will also place as a background image on all the VIs, a watermark of the company name, legality stuff and the copyright. It works very slick in that if there are thousands of sub-vis, such as what I'm working on now, it goes through all of them, makes sure the data is there as per company policy without having to open every one of them look at them and update or not whichever the case may be. The one portion that is tough is that the program will detect if there is a description written about what funtion the VI performs and if there is not a description, then it pops up a dialog requesting the user to write a description. The problem is that without looking at the block diagram for the VI, it can be nearly impossible to write a description for the functionality of the VI. So is there a way to programmatically open a VI, show its block diagram (this would only be in the case of a missing description) and then upon completion of the updates, close the block diagram? (I already open and close the VI programmatically in order to read the VI DESC and update as needed, but that is in the background and of course you can't see the block diagram).
Thanks,
Dan

How to validate XML using java_xml_pack-summer-02?

In jaxp1.1, we validate the xml file in this way:
c:\java -jar Validator.jar myBookStore.xml
However, in java_xml_pack-summer-02, which is latest version of jaxp, the Validator.jar is not available. So, how to validate xml file?
Pls help.

develop your own validator... here is a quick and dirty one, which spits exceptions when error are met:
import java.io.*;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
public class Validator
public static void main(String[] args) throws Exception {
    SAXParserFactory spf = SAXParserFactory.newInstance();
    spf.setValidating(true);
    spf.setNamespaceAware(true);
    SAXParser sp = spf.newSAXParser();
    sp.parse(new File(args[0]), new DefaultHandler());
}

How to programmatically load and show the front panel of a vi but NOT run it?

Is there a way to load and show the front panel of a vi but NOT run it? I am starting with the AsynchronousCallAndForget.vi from the example finder and inserted an invoke node with the FP Open method call prior to the Start Asynchronous Call node. The vi I am loading has the "Run when opened" unchecked and the menu bar IS visible so I can manually click the run arrow. Thanks!
Solved!
Go to Solution.

Why are you using the Async call? If you simply open the VI reference, then call the FP.Open method this works fine. You can then call the VI run method with Wait Until Done set to false if you wish to run it Asynchronously, this is how we did it in ye olde days before we had this new fangled "Start Asynchronous Call" stuff.
