Discussion of xml representation types

I have a discussion with a college about representations of xml data to be passed between webservice and client applications.
My Suggestion: org.w3c.dom.Document - as it appears most "modern" ways/apis or parsing xml take this as a native input and there would be no need to convert to an inputSource or other type.
Other Suggestion: A String object - supposedly because it is generic enough to be used by others.

I would still follow the standards. Serialize the XML to bytes. I don't see any point in treating so-called "internal" applications differently, it just makes it harder for people to maintain them in the future.
Besides, there's a rule that I call the "HMS Pinafore" rule of system design:
Chorus: What, never?
Singer: No, never!
Chorus: What, NEVER?
Singer: ... Hardly ever.

Generating an XML representation of arbitrary Java objects

Hi. Just for fun, I'm attempting to write some code which creates an XML representation of an arbitrary java object using reflection. The idea is that only properties with get/set methods should come through in the XML.
Here is the code:

XML Data Type in oracle

I am a developer in .NET with having experience working on SQL server.
I want to know whether there is an xml data type in oracle.
I have an xml in my front end and want to insert record in the database for the values inside that xml. What i am doing currently is that i am retreiving the value in the xml in the .NET code and passing the values a parameter to a stored procedure in oracle. what i want to do is to pass the xml directly to stored procedure in oracle and retrieve the values there (using Xquery) and insert the records.
This is possible with SQL server 2005. I want to know is this possible with Oracle.
Thanks and regards,
Sameer J Narkar

Wonderful - a documentation question!
You will find your answer by going to the general documentation portal at http://tahiti.oracle.com following the path to the database version of interest, and looking in the SQL Reference manual. Chapter 2 discusses all data types, including the several supported for XML.
In addition, under the 'Books' tab, there are several XML-developer specific reference manuals.
(Oracle's support for XML generally blows away the others. The price for the extreme flexibility is an ease-of-use hit.)

DSC with XML data type

Hi,
Can someone explain to me what the difference is between the xml data type and the Document data type in workbench? I would like to use the xml datatype in my DSC thinking it is most likely the best representation of an xml string. But I've heard that Document is more widely used and that it can represent an xml entity as well. Is this right?
My ultimate goal is to write a DSC and use a type that represent an xml string. I would like the component.xml to have the type for my input variables to automatically be typed as "xml" or "document" (whatever the one i should be using is).
I tried creating variables of both types ("xml' and "document", lower case d) and have those passed into my DSC for inspection. The object passed in are as follows:
xml: org.apache.xerces.dom.DocumentImpl
document: com.adobe.idp.Document
But if I use any of those in my component.xml, workbench is typing my variables as "DocumentImpl" or "Document".
Any ideas?
Thanks in advance!
Nic

The xml variable (org.w3c.doc.Document) is a native xml data type. That means you can use xml functions and/or xPath expressions on the content of the variable.
The document variable (com.adobe.idp.Document) is a more generic data type that can store any binary data. If you happen to store xml in that data type, you won't be able to run xml functions or xPath expression directly on the variable content since it's treated as binary data.
If you don't need to manipulate or access the content of the xml, then either data types will work. Otherwise, I would use the xml data type.
In your component xml, make sure your xml data type is set to org.w3c.doc.Document and you'll see xml in Workbench.

Named file entity do not load in from xml files(eg., !DOCTYPE PURANA SYSTEM "purana.dtd" [ !ENTITY CHAPTER_1 SYSTEM "./chapter_1.xml" ] ?xml-stylesheet type="text/xsl" href="purana.xsl"? PURANA TITLE /TITLE &CHAPTER_1; /PURANA )

I create several file name entities in an external DTD.
It used to work sometimes back but I don't remember now when it begun to fail.
typical document for eg., is given below:
<!DOCTYPE PURANA SYSTEM "purana.dtd" [ <!ENTITY CHAPTER_1 SYSTEM "./chapter_1.xml"> ]>
<?xml-stylesheet type="text/xsl" href="purana.xsl"?> <PURANA>
<TITLE>
</TITLE>
&CHAPTER_1;
</PURANA>)
the abbreviation used to work by loading the file using XSL script,
but now it does not even work when the entity is defined within the XML document itself.

Too difficult???
Please helped me.
Thank you, Theo

(261705413) Q RPCC-21 Missing text/xml MIME-type for WSDL files?

Q<RPCC-21> Would it mess up the SOAP operations that clients do when using the
WSDL in a dynamic client to put a text/xml mime type in the WSDL-providing jsp?
A<RPCC-21>: It is a known issue that the MIME-type for WSDL files is not appropriately
transmitted so some web browsers will not identify an appropriate helper application
when they are viewed (for Netscape just press Ctrl-U to view the source). This,
however, does not affect the dynamic client as evidenced by the example code seen
in the code demonstration.

SR,
You probably already have the answer by now, but I just came across the same problem and found the answer elsewhere.
The trick is to have the JavaMail jar in your classpath BEFORE the JAF jar. Given the habit of my development environment to sort jars alphabetifally it had me stumped for a bit.
Good luck

Identifying an XML document type

I am reading XML message off a queue using JMS and I want to determine the XML document type so I can use the proper schema for validation. Since different XML documents will be coming in off the same queue I need to determine the document type so I can use the proper schema for validation.
Is there a good way to do this? So far I have been doing the following but I am looking for a better solution:
*Use the JMS headers to store the XML message type. Not always possible.
*Read the first few lines of the XML as a file and parse for the root node or .xsd.

What I am refering to is a situation where I have one queue that has multiple incoming XML documents.
For example:
PurchaseOrder.xml needs to be read off a queue validated via PurchaseOrder.xsd
PartsOrder.xml needs to be read off the same queue and validated with PartsOrder.xsd. I am trying to find and eloquent solution to identify if I have a PartsOrder or a PurchaseOrder, so I can set the proper schema for validation when parsing the XML doc.

----While running the SP manually below error occured

HI ,
1. You cannot use a table or view that contains xml or clr type as 4-part name in your query
2. You need to cast the column to either nvarchar(max) or varbinary(max) or other appropriate type to use
3. If you have a table that has xml type for example then you need to create a view that contains all columns other than xml and query it instead. Or you can issue a pass-through query using OPEN QUERY with the appropriate columns only.
Here is a work around:
SELECT
Cast(a.XML_Data as XML) as XML_Data
FROM
OPENQUERY([LINKED SERVER NAME HERE],'
SELECT
Cast(XML_Data as Varchar) as XML_Data
FROM
[DATABASE NAME].[SCHEMA].[TABLE NAME]'
) a
Basically, the data is queried on the remote server, converts the XML data to a varchar, sends the data to the requesting server and then reconverts it back to XML.

Xml representation of a string

hi all,
how do i make an xml representation of a string..if anyone knows please post it.
thanks

wow, you guys must be all in the same class, that's 3 times this question has been asked. Look below...

XML dateTime type with timezone info.

Has anyone have problem FTPing xml that conforms to a xml schema with dateTime type?
This is the format of standard XML dateTime type:
"2003-12-17T09:30:47-05:00"
I used the Oracle timestamp datatype, but oracle rejected the dateTime of XML with the error message
"ORA-01830: date format picture ends before converting entire input string."
I have altered the database to use timezone information:
// For eastern time zone.
alter DATABASE SET time_zone = 'Etc/GMT-5';
and use the native oracle datatype
"TIMESTAMP WITH TIME ZONE"
but still doesn't work. I also changed the XML time data to "2003-12-17 09:30:47-05:00", still no good.

I tried couple formats, they all seem to need the "T" in between date and time. If I don't have the "T", I get the error message "ORA-01861: literal does not match format string"
If I use the following input I get the error message
"ORA-31041: Property CreateDate: Memory type (180) not compatible with database type (121)"
"2003-12-11T21:30:47.0"
"2003-12-11T21:30:47.000000"
"2003-12-11T21:30:47.000000000"
"2003-12-11T21:30:47000000"
"2003-12-11T21:30:470000"
If I use the following I get error message "ORA-01830: date format picture ends before converting entire input string"
"2003-12-11T21:30:470000-04:00"
"2003-12-11T21:30:47.000000-05:00"
"2003-12-11T21:30:47.0-05:00"
It leads me to think that "2003-12-11T21:30:47.000000"
is the picture(mask) used by the database. But it has extra "T" in it, and oracle doesn't understand the datatype. Maybe there are two validation going on? one from schema and another during insertion to database? Schema requires "T", but database doesn't understand "T"?
Am I in the right track?
Do you know how do I query the mask used?
Thanks,
--Benjamin

[JAXB 2.x] Defining the XML Schema Type for XmlElementDecl

How can an XML Schema Type (XmlSchemaType) be defined for an XmlElementDecl/Ref?
The classes are as follows:
    @XmlRegistry
    class ObjectFactory {
        // XmlSchemaType is desired, but cannot be used with XmlElementDecl/Ref: @XmlSchemaType(name = "unsignedShort")
        @XmlElementDecl(namespace = "urn:com:test:namespace", name = "char", scope = com.test.Arguments.class)
        @XmlJavaTypeAdapter(com.test.CharacterAdapter.class )
        public JAXBElement<Character> createArgumentsChar(Character value) {
            return new JAXBElement<Character>(_ArgumentsChar_QNAME, Character.class, com.test.Arguments.class, value);
    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "", propOrder = { "arguments" })
    class Arguments {
        @XmlElementRefs( {
                @XmlElementRef(name = "char", namespace = "urn:com:test:namespace", type = JAXBElement.class),
        protected List<JAXBElement<?>> arguments;
    }The desired schema is as follows:
    <xs:element name="arguments" minOccurs="0">
        <xs:complexType>
            <xs:sequence>
                <xs:choice minOccurs="0" maxOccurs="unbounded">
                    <xs:element name="char" type="xs:unsignedShort" />
                </xs:choice>
            </xs:sequence>
        </xs:complexType>
    </xs:element>However, when generating the schema from these classes (schemagen), the resulting "char" element type is "xs:string," not "xs:unsignedShort" as desired. What annotation can be used to indicate that the type should be xs:unsignedShort? If the addition of an annotation is not possible, are there any other ways to accomplish this?

XML Data Type

Hi
Does the latest version of Designer support XML Data Type?
Thanks,
Ila

No there is no direct support for XML datatype..
However, you can follow Note 204966.1 Using Designer Domains to Exploit New Datatypes
hope this helps
