Cant' constraint DOM editing operations with a schema

Hi,
I use the DOM for editing an XML document. I want to control editing operations with a schema. I use something like that:
DOMParser domParser = new DOMParser();
domParser.setValidationMode(XMLParser.SCHEMA_VALIDATION);
XSDBuilder builder = new XSDBuilder();
URL url = new URL(SchemaUrl);
XMLSchema schemadoc = (XMLSchema) builder.build(url);
domParser.setXMLSchema(schemadoc);
domParser.parse(XmlDocumentUrl);
// here i want to remove an empty node
if ((node.getNodeType() == Node.ELEMENT_NODE) && (!node.hasChildNodes())) {
NodeEditVAL node2edit = (NodeEditVAL)node.getParentNode();
if ( (node2edit.canRemoveChild(nodet) == XMLNode.VAL_TRUE )) {
node.getParentNode().removeChild(node);
canRemoveChild() always returns VAL_TRUE even if the node is mandatory according the schema.
Thanks for your help,
Philippe

Hi Philippe,
I wrote a test case and I am observing the same behaviour as you. I have logged an internal bug against the XML parser team. I will post a reply when I get more information from them.

Crash of Oracle XE when check constraint uses in-operator with desc. values

ORA-03113 and other errors in conjunction with lost of connection occur in Oracle XE under the following conditions:
/* Crash (values of check constraint in descending order) */
DROP TABLE CRASHTEST CASCADE CONSTRAINTS;
CREATE TABLE CRASHTEST
CRASHTEST_ID NUMBER(9),
CRASHTEST_OK NUMBER(1) DEFAULT 0
ALTER TABLE CRASHTEST ADD (CONSTRAINT CRASHTEST_CK CHECK (CRASHTEST_OK IN (0,-1)));
INSERT INTO CRASHTEST (CRASHTEST_ID, CRASHTEST_OK) VALUES (1, 0);
INSERT INTO CRASHTEST (CRASHTEST_ID, CRASHTEST_OK) VALUES (2, -1);
COMMIT;
SELECT * FROM CRASHTEST WHERE CRASHTEST_OK = 0;
If all values of the in-clause within the check constraint are entered in ascending order, no error occurs:
/* No Crash (values of check constraint in ascending order) */
DROP TABLE CRASHTEST CASCADE CONSTRAINTS;
CREATE TABLE CRASHTEST
CRASHTEST_ID NUMBER(9),
CRASHTEST_OK NUMBER(1) DEFAULT 0
ALTER TABLE CRASHTEST ADD (CONSTRAINT CRASHTEST_CK CHECK (CRASHTEST_OK IN (-1,0)));
INSERT INTO CRASHTEST (CRASHTEST_ID, CRASHTEST_OK) VALUES (1, 0);
INSERT INTO CRASHTEST (CRASHTEST_ID, CRASHTEST_OK) VALUES (2, -1);
COMMIT;
SELECT * FROM CRASHTEST WHERE CRASHTEST_OK = 0;
Especially interesting is the fact, that the error is caused by a check constraint in conjunction with a select statement!
Hopefully, there are no other hidden bombs stealing my time...
Have a nice day,
Sven

It might be interesting to post that in the XE forum to notify Oracle developers and XE users.

ERROR: MyService.jws:715:There are two or more operations with the same schema-element 'ns0:MyNameSpace' on the input message in a web service file or callback interface.

I have two web service operations that have the same complex type as their input
parameter. I want to map this type to an existing schema. I can successfully
do this with the first operation using XQuery but when I attempt to do this with
the second operation I get the following error:
ERROR: MyService.jws:715:There are two or more operations with the same schema-element
'ns0:MyNamespace' on the input message in a web service file or callback interface.
ERROR: SUGGESTION: Use different schema-element values for each of those operations.
How can I use different schema-element values? The input parameters are to be
mapped to the same schema and same element since they are the same for both operations....

I am having the same problem. How did you resolve this..?? could you please tell me the solution??
Thanks

Can an editable form be saved so it cant be edited again with Adobe Reader?

Im creating PDF forms for someone. They are using Adobe Reader to fill out the form fields on the PDF. They will be sending it off to others after. What I want to know is with Reader, is there a way that after they fill out the information, they can save it so it cant be re-edited or anything?

You would have to set up a button, bookmark, or something else that when triggered runs a script that sets the fields to read-only. You will have to set this up in Acrobat before you Reader-enable the document and distribute it.
Here's some code that sets a single field to read-only:
getField("Text1").readonly = true;

UDPATE:
Spoke with Express lane, and issue was escalated. Kudos to the support guys that handled this one (Brian and Yi). Went through everything in detail and took all the crash dumps off the iphones and ipads to send to engineering.
After backing up the contacts, the recommendation was to delete all contacts in iCloud. Doing that caused my iCloud to crash (in the browser), so more crash dumps were sent to apple.
Eventually got all contacts deleted, then did a resync. Looks like IOS devices are coming back to life and syncing again.
Also, Outlook iCloud connector has just been updated to ver 1.0.1 so i installed that on their recommendation.
BOTTOM LINE workaround:
1. Backup contacts
2. Delete contacts in iCloud
3. Delete accounts on IOS devices
4. Recreate accounts on IOS devices.
Hoping a real root cause can be found and real fix implemented. This has caused me to doubt the stability of iCloud, so i will procees with caution.

Does Oracle not support element reference to other element with dot?
For instance, body -> body.content

Catch all error information while validating xml content with xsd schema

Hi experts,
I created a java mapping to validating the input xml content with xsd schema (schema validation). What I want is to catch all error message to the xml not just the first error. I used SAXParser in sapxmltoolkit.jar to do the schema validation. The below is a part of my java mapping.
XMLReader parser = XMLReaderFactory.createXMLReader("com.sap.engine.lib.xml.parser.SAXParser");
parser.setFeature( "http://xml.org/sax/features/validation" , true);
parser.setFeature( "http://apache.org/xml/features/validation/schema" , true);
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");          parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource",this.getClass().getClassLoader().getResourceAsStream(schema)); // schema is my schema name
parser.setErrorHandler(new ParseErrorHandler()); // ParseErrorHandler is my own ErrorHandler which extends DefaultHandler
parser.parse(new InputSource(new ByteArrayInputStream(sinput.getBytes())));
// In error handler, I comment all code so as not to throw any exception
public class ParseErrorHandler extends DefaultHandler
     public void error(SAXParseException e) throws SAXException
          // sSystem.out.println("Error" + e.getMessage());
          // throw e;
     public void fatalError(SAXParseException e)
          // throw e;

VS 2013 error: "Attempted TextBuffer edit operation while another edit is in progress"

I´m using Visual Studio 2013 Version 12.0.21005.1 with VB.NET on Framework 4.5.50938, OS is Windows 7 SP1 32 Bit.
I´m randomly getting the error message
"Attempted TextBuffer edit operation while another edit is in progress"
when trying to edit a source file. The file then remains inaccessible until I restart Visual Studio.
This message seems to appear at random and out of nowhere, sometimes after running or debugging the program, sometimes in the middle of editing. I can edit one file, switch to another one and receive this error.
Sometimes I can work half an hour before this message appears, sometimes only a couple of minutes. I´ve been looking all over the web for solutions but can´t find anything.
This error is beginning to severely disturb my work, so any ideas would be highly appreciated.

Hi AndyF69,
Sorry for that we couldn’t repro this issue.
Please check whether you install any add-ins or extension tools in your VS, please disable/remove them, and check it again. I doubt that it would be related to them.
Please also run your VS in safe mode.
http://msdn.microsoft.com/en-us/library/ms241278.aspx
If still no help, please re-install/repair your VS.

Remember: we cannot see your machine. There are 9 different versions of iPhoto and they run on 8 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Basic things like :
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For instance: 'iPhoto won't export' is best explained by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted?
- Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have.

Error in multiple operation with change document object for custom table

hi all,
I have developed a change document object for a custom table ZTEST and developed a report program for insertion, updation & deletion..everything works fine if I do only once ie. if I created only 1 entries. If I created 2 new entries , I am getting an Error "DUPREC:POS&Z3RL_TAB&Z3RL_TAB" and EXIT the transaction.
why I am getting this error??? is it not possible to do multiple operation with the change document???
kindly help.

Mapping with xml-schema XML-data to relational tables

Hello,
is it possible to map data from xml documents to relational tables with xml-schema?
I mean not in nested tables but in relational tables with primary and foreign keys!
With SQL Server 2005 it is very easy, I dont believe that Oracle couldn't do this!
I searched but i cant find anything about that!
Thx
user445232

indeed, oracle does this for xml schema based xmltype data, however, these underlying tables are not accessable to the application. Maybe It should for next version, so folks who like to use relational model can use it without mapping it manually.
Actually, nested tables, are the same, their underlying tables (segments) are indeed relational tables, oracle manages them internally and not visiable to the application. You can find them in the user_segments, user_objects views though.

JDeveloper - ESB / BPEL - JMS Adapter - prefix queue name with db schema

When I use the JMS Adapter in ESB to create a new message queue producer or consume using database (AQ) I'm experiencing a problem when selecting the queue.
I can browse the queue in the database but when I have selected the queue JDeveloper prefix it with the schema name owning the queue.
Example:
java:comp/resource/DocumentQueueResourceProvider/Queues/QUEUES.DOCUMENT_IMPORT_QUEUE
Schema owner is QUEUES and the name of the queue is DOCUMENT_IMPORT_QUEUE.
The problem is when I try to use it its unable to look up the queue and I have to manually remove the prefix from .wsdl file before deploying it - as with setting mcf.IsTransacted='false'.
When the resource provider finds the queue and exposes it in the JNDI three it does it without the prefix.
Question: How do I either:
a) make the schema prefix be removed by JDeveloper
b) make the resource provider prefix the queue name with the schema name.
Anybody?
Best regards
Christian Damsgaard

Problem with database schema objects in the entity object wizard

Hi All,
When creating a new entity object, I am facing a problem with database schema objects in the entity object wizard, database schema objects (check boxes for tables,synonyms...) are disabled. Actually I am using a synonym but I am not able to select the synonym check box.
Can any of you folks tell me how to enable the database schema objects (check boxes for tables,synonyms...).
Thanks in Advance.

Edit Procedure with selected values

Hi,
I have an edit form where i drugged my view as an adf form.
I created in my Application Module a method called "save()" which what i do is just commit:
try {
getDBTransaction().commit();
} catch (JboException ex) {
getDBTransaction().rollback();
throw ex;
On my form i have some radio buttons. One of them is called LandType, with two options (OptionA and OptionB).
Please note that this is an edit operation so there is a preselected value when i edit a record.
I created some entity level validation which is conditional based on the selection of the above radio button. For example i have 2 input boxes, "InputA" and "InputB". If the user selects "OptionA" the "InputA" is required. If the user selectd "OptionB" then "InputB" is required.
For the create operation everything runs smoothly.
For the edit operation i face this problem.
I have a record with "OptionA" selected and "InputA" with some value ("InputB" is empty)
When i change to "OptionB", i render the "InputB" text box and i get my error message for an empty field("InputB"). If i press again save (calls my commit method in my AppModule) then the radio button from "OptionB" goes back to "OptionA" and if i click again save, it saves the changes!!!
How can i overcome this? I want the new value selected to remain.
Thanks
Antonis

Some glitch in my blogging software currently prevents me from posting it on my blog, but I've uploaded a 10.1.3.3-based example workspace here:
http://otn.oracle.com/products/jdev/tips/muench/condreq/OptionalRequiredFields.zip
This is the example blurb that will eventually appear as example #124 on my blog when I am again able to upload to it.
This example illustrates how to validate and render
conditionally-required attributes. After running the included
CreateTables.sql script to create the
OPTIONAL_REQUIRED_TEST table, run the TestPage.jspx to
see that when a row has its RowType attribute set to the value
A then the ValueA inputText component renders, while if
its RowType attribute is instead set to the value B then
the ValueB inputText field renders. These fields set the
showRequired property to true to show the required field
indicator to the end-user even though the underlying ValueA and
ValueB attribute are not marked as mandatory. The conditional
mandatory validation is performed in the TestEntity entity
object using entity-level method validators. The radio group UI
component is marked to have its autoSubmit property true, and
the ValueChangeListener method in the backing bean for the page
sets a request-scope attribute as a flag to indicate that the row type
is changing. This flag is then referenced by the
ConditionalValidationPageController -- identical in function to
the one you might have seen in Example# 62 "Cascading Lists in JSF" --
which is configured to be used by the TestPage by setting the
ControllerClass property of its page definition. This
customized page controller avoids validating the row if it detects
that the row type is changing. The conditional rendering of the ValueA
or ValueB inputText components is handled declaratively using an
appropriate EL expression for the component's rendered
property. When the autoSubmit radio group (with component id
"RowTypeRadio") causes its partial-page request, the panelForm
component in which the ValueA and ValueB inputText's reside is
declaratively "repainted" by having its partialTriggers
attribute set to that "RowTypeRadio" id value. By performing the
partial-page triggering on the enclosing panelForm component, you
avoid the gotchas related to having PPR events delivered to
currently-unrendered components.
