Use prefix when a default namespace

I'm trying to use the SimpleDateFormat.format() function in the following way but it obviously doesn't work. Is there way to do this?
<%
SimpleDateFormat formatter = new SimpleDateFormat("MMM-dd-yyyy", Locale.CANADA);
%>
<td>${formatter.format(client.birthdate)}</td>

You're trying to invoke a reference in EL which is declared in a scriptlet. That isn't going to work. Do the one or the other. You can also consider the fmt:formatDate tag of the fmt taglib [1]. It also makes use of the SimpleDateFormat.

"...Prefix when a default namespace..." error inside javascript

I get this exception:
The function $ must be used with a prefix when a default namespace is not specified
in this piece of jsp code
<html:checkbox property="copyAddress" value="true"
onclick="if (this.checked) { $('postal').hide()} else { $('postal').show(); }"/>Also, I get this error locally but not in the server. I use tomcat 5.5, jsp-api 2.0 and servlet-api 2.4.
What's wrong? Please help me
Edited by: poroto20 on Jan 13, 2010 6:56 AM

I would move this method over to its own function and pass the arg in full.
Also if this is JQuery then it sould read, if this is Struts then there are better ways of doing this.
if (this.checked) { $('#postal').hide()} else { $('#postal').show(); }"
{code}
When you create the method wrap it up in a try catch (Javascript try catch) and see what outputs. You can also use Firefox/Firebug to get better debugging information regarding JS errors.
Also you should read as follows, otherwise you will get a JS error
{code}
if (this.checked) $('postal').hide(); else $('postal').show();
{code}
Note the ";" after the hide();

Is it possible to use a CONSTANT as Default Namespace?

Hi,
I create from a table and an XML-field a view. For the command XMLTABLE I have to use a DEFAULT namespace.
Is it possible instead of a fixed string to use a constant variable which I read using a function?
As example:
CREATE OR REPLACE VIEW pain_001 AS
SELECT i.iban_ausz_id IBAN_AUSZ_ID
,oc.PmtCdtInstrId PmtInf_CdtInstrId
FROM IBAN_AUSZ_E i
,XMLTABLE(XmlNamespaces(DEFAULT 'http://www.six-interbank-clearing.com/de/pain.001.001.03.ch.02.xsd'),
'/Document/CstmrCdtTrfInitn/PmtInf/CdtTrfTxInf'
PASSING i.pain_001
COLUMNS
PmtCdtInstrId NUMBER PATH 'PmtId/InstrId'
) oc
I want to replace 'http://www.six-interbank-clearing.com/de/pain.001.001.03.ch.02.xsd' with a function wich returns a constant variable like "package_name.get_const".
Is this possible?
Thanks in Advance.

Is this possible?No, it's not possible. It has to be a string literal.but for dynamic sql (EXECUTE IMMEDIATE) looks like it's possible

Format using default namespace prefix.

Is there any way to format XML using default namespace prefix in an expression?
My expression is as follows:
oraext:get-content-as-string(bpws:getVariableData('JmsMdx_InputVariable','body'))

This seems wrong to me. I've filed Bug 2400119 to get this looked into by development.
I'd expect any document with an appropriate qualified name to be found by your XPath expression, irrespective of whether syntactically one of the documents happened to use the default namespace syntax.

Output XML with a default namespace using XQuery

I'm having a problem with namespaces in an XQuery within ALSB.
We receive XML from a file which doesn't have any namespace and have to transform it into a different structure, giving it a default namespace such as below:
Input XML
<inputRoot>
     <inputAccountName>Joe Bloggs</inputAccountName>
     <inputAccountNumber>10938393</inputAccountNumber>
</inputRoot>
Desired output XML
<outputRoot xmlns="http://www.example.org/outputSchema">
     <outputAccounts>
          <outputAccountName>Joe Bloggs</outputAccountName>
          <outputAccountNumber>10938393</outputAccountNumber>
     </outputAccounts>
</outputRoot>
When I attempt to do this using XQuery mapper tool, I end up with a namespace prefix on the outputRoot. The XQuery and result follows:
XQuery
declare namespace xf = "http://tempuri.org/XQueryProject/scratchTransformations/test/";
declare namespace ns0 = "http://www.example.org/outputSchema";
declare function xf:test($inputRoot1 as element(inputRoot))
as element(ns0:outputRoot) {
<ns0:outputRoot>
<outputAccounts>
<outputAccountName>{ data($inputRoot1/inputAccountName) }</outputAccountName>
<outputAccountNumber>{ data($inputRoot1/inputAccountNumber) }</outputAccountNumber>
</outputAccounts>
</ns0:outputRoot>
declare variable $inputRoot1 as element(inputRoot) external;
xf:test($inputRoot1)
Result
<ns0:outputRoot xmlns:ns0="http://www.example.org/outputSchema">
     <outputAccounts>
          <outputAccountName>inputAccountName_1</outputAccountName>
          <outputAccountNumber>inputAccountNumber_1</outputAccountNumber>
     </outputAccounts>
</ns0:outputRoot>
How can I write the XQuery in such a way thay the namespace prefix isn't output? I've tried many different methods with no success. I can't declare a default element namespace because my input element doesn't have a namespace
Thanks in advance

I spoke too soon, it didn't work quite as perfectly as I'd thought :-) It turns out our client can't handle the xml with the namespace prefix but we've worked out the solution to return XML in the format we originally needed.
Example below:
XQuery
declare namespace xf = "http://tempuri.org/XQueryProject/scratchTransformations/test/";
declare default element namespace "http://www.example.org/outputSchema";
declare namespace ns1 = ""
declare function xf:test($inputRoot1 as element(ns1:inputRoot))
as element(outputRoot) {
<outputRoot>
<outputAccounts>
<outputAccountName>{ data($inputRoot1/inputAccountName) }</outputAccountName>
<outputAccountNumber>{ data($inputRoot1/inputAccountNumber) }</outputAccountNumber>
</outputAccounts>
</outputRoot>
declare variable $inputRoot1 as element(inputRoot) external;
xf:test($inputRoot1)

XML DB: using default namespace gives different result

In Oracle9i R2 I created an XMLTYPE table based on a XML schema. The schema uses a namespace. When I insert an instance document that has a namespace prefix for every element querying works fine. When I insert an instance document that has the namespace defined as the default namespace, the query returns an empty row for that document. It seems to me that before storing the document the namespaces must be expanded and hence there should be no difference between the two documents and the query should return a value for both rows. Any thoughts? Thanks in advance! Below is the script and the results of the queries.

This seems wrong to me. I've filed Bug 2400119 to get this looked into by development.
I'd expect any document with an appropriate qualified name to be found by your XPath expression, irrespective of whether syntactically one of the documents happened to use the default namespace syntax.

Can you validate an XMLElement that uses the default namespace?

We have a partner that we communicate with via XML over HTTP and the schema that they gave us for their request/response does not specify a namespace. I am able to import the schema and create variables from its elements to send the request and get a response back but when I try to validate the response I am getting an error.
We are using SOA Suite 11g and the bpelx:validate action to try to validate the variable but it consistently gives back the following error message.
java.lang.IllegalArgumentException: null schema location for ns=null [Cause=null schema location for ns=null]
I am pretty sure this is because there is no namespace specified in the response data. Is there anyway that I can validate this XML against the schema without a namespace? This is an existing interface that we are converting so we don't have the flexibility to ask the partner to change their interface. I am able to validate the same XML data in XML Spy against the schema and have been able to recreate this problem with a different small xsd with the default namespace.
I think I can write a java utility to perform the validation and call it using the embedded java action but I am hoping there is a way to do it within the tool.

How to suppress n0: default Namespace prefix in Transformations

Hi,
I use Simple Transformations for serialization of deep structured data.
In the XML File the whole tree needs to use a special namespace. Therefore i use the attribute xmlns="ABC.de" without a namespace prefix in my root element. During serialization SAP generates a default namespace prefix like 'n0:'.
Is it possible to suppress the generated namespace prefix?
Thank you very much for reply
René
Edited by: René Libbert on Feb 14, 2012 8:09 AM

Maybe somebody is interested.
It seems to be a problem on old 640. On a NW 702 the result is as expected. NW 700 was not tested.
Workaround for the 640 is to use as result a STRING field not an XSTRING.

SELECT returns no result when there is a default namespace definition inXML

Hi,
I have a problem that my select doesn't return any result when there is a default namespace definition in my XML file.
I'm using oracle 11g release 1
XML file stored as a binary XML:
<SIMS xmlns="http://sims.ics.muni.cz" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://sims.ics.muni.cz jh_sims_matricni_vystupy_or.xsd">

This select return no result:
SELECT student.jmeno FROM jh_sims_bin_no_schema s, XMLTable('/SIMS/Vystup/Student' PASSING s.OBJECT_VALUE COLUMNS jmeno VARCHAR2(10) PATH 'Jmeno') student
When I remove default namespace definition (xmlns="http://sims.ics.muni.cz") everything works fine and the same SELECT returns "Petr". Also when the file is stored in object relational storage everything works fine!

Thanks for any help!
Jan Hruby

Hi Jan,
You need to specify the default namespace of the document in the XMLNamespaces clause :
SELECT student.jmeno
FROM jh_sims_bin_no_schema s,
     XMLTable(
      XMLNamespaces(default 'http://sims.ics.muni.cz'),
      '/SIMS/Vystup/Student'
      PASSING s.OBJECT_VALUE
      COLUMNS jmeno VARCHAR2(10) PATH 'Jmeno'
     ) student
;

Suppress default namespace when extracting XML

How can I avoid that Oracle includes the target namespace of my schema as the default namespace when using the EXTRACT function?
E.g., select xmlelement("XmlData",
xmlagg(extract(tx.transmission, '/Transmission/Item')))
from transmissions tx
returns something like
<XmlData>
<Item xmlns="http://myschematargetnamespace" N="1">abcdef</Item>
<Item xmlns="http://myschematargetnamespace" N="2">abcdef</Item>
</XmlData>
Any ideas will be appreciated very much!
P.S. Can anybody tell me how I configure sqlplus to display the complete XML instead of only two lines?

Well not sure about your XML issue yet but as for SQLplus, you need to set certain session parameters.
type
SQL> show all
for a list of possible options but for your case I think something like
SQL> set long 10000
will help (this means limit to 10000 chars).
'set linesize' and 'set pagesize' could help too, eg:
SQL> set linesize 500 (if your terminal will accept 500 cols)
SQL> set pagesize 90
etc...
Voila.

I have two apple id accounts ,when i used to update application it used to prompt a default id and if the application was downloaded using the other id i would cancel and it would prompt the other id but not any more .

i have two apple id accounts ,when i used to update application it used to prompt a default id (the old one) and if the application was downloaded using the other id i would cancel and it would prompt the other id but not any more .
it just prompt the old id which im not signed in with im signed in using the new id and when i cancel nothing happens and when i try to update applications separately i have the same problem .
im signed in using the new id
the old one is my wife's so i can't delete it
the problem happens when i update all or each application by its own
using ios 5.0.1 on a iphone 3gs
the applications are downloaded using both the new and old id's
any help will be greatly appreciatedِ

These are user-to-user forums, you are not talking to Apple here and they don't monitor these forums - I've asked the hosts to remove yout account ids from your post.
In terms of combining accounts it's not currently possible to do so, nor to copy/transfer content from account to another.

Assign default namespace to XML fragment using XQuery

Hi everybody!
I need to add a default namespace declaration to a XML fragment using XQuery. I wrote following statement to assign fragment to $body:
<soap-env:Body>{
fn-bea:inlinedXML($content/text())}
</soap-env:Body>
The problem is "$content/text()" has no namespace declaration so I need to assign a default namespace (xmlns="") to it in order to apply some XQuery transformations to its content.
I know this can be easily done with a XSLT but I would like use XQuery instead.
Could anyone tell me how I could perform this task?
Thank you in advance,
Daniel.

Resetting Default Namespace Using JDOM

Is it possible to reset the default namespace on a JDOM Document? I've tried setting a namespace declaration on the root element with the following code:
Element myRootElement = myDocument.getRootElement();
Namespace namespace = Namespace.getNamespace("http://whatever.com");
myRootElement.addNamespaceDeclaration(namespace);Since the Document already has a default namespace, I get the following stack trace:
org.jdom.IllegalAddException: The namespace xmlns="http://whatever.com" could not be added as a namespace to "rdf:RDF": The namespace prefix "" collides with an additional namespace declared by the element
at org.jdom.Element.addNamespaceDeclaration(Element.java:339)Does anyone have any suggestions or hints? Perhaps its not even possible? Thanks in advance for any help.

pass the RootElement to the following method:
public void someMethod(org.jdom.Element element) {
org.jdom.Namespace xhtml = org.jdom.Namespace.getNamespace("html","http://www.watever.com");
if (element.getNamespace() == org.jdom.Namespace.NO_NAMESPACE) {
element.setNamespace(xhtml);
java.util.List childElements = element.getChildren();
java.util.Iterator iterator = childElements.iterator();
while (iterator.hasNext()) {
org.jdom.Element child = (org.jdom.Element) iterator.next();
someMethod(child);
}

Use prefix when a default namespace
