How to use java to create an XML document from an SQL database?

Hi,
I'm a complete novice at XML and have only recently started programming in Java.
I'm currently trying to develop a package in Java 1.1.8 which requires a set of very specifically formatted XML documents. These documents would need to be updated regularly by people with no knowledge of Java and I would like to make it as simple as possible.
Since the data will already be in an SQL database, I thought it might be possible to generate the XML documents from the data using a small Java application, but I'm not too sure how to go about this or if this is even possible! Any help or pointers in the right direction would be very much appreciated.

Do you have the option of upgrading to a newer version of the JDK?
JAXB does what you are wanting very easily. Also there are tools if you don't want to write your own. JAXB is available as early release on Sun's site as is the newest JDK. Otherwise, you have to design a factory and interface that will do this for you (which is what JAXB basically is in a very simplified view).

Error while generating an XML Document from XML Schema with JAXB

Hi,
I am following this OTN tutorial to generate the XML document from Java classes got from the XSD document.
http://www.oracle.com/technology/pub/notes/technote_jaxb.html
I am able to generate all the Java classes but getting error on compiling the XMLConstructor.java class which is use for generating the XML document :
I am using JDK 1.5 and
Oracle 10g XML Developer's Kit (XDK) Production for Java. xdk_nt_10_1_0_2_0_production
(though these are warnings I am not able to run it.)

Generating an XML Document from an internal table in ABAP

Good day to all of you;
With ABAP, in the R/3 system, I'm trying to figure out a way to accomplish the following:
1) SELECT a set of Purchase Order data into an internal table.
2) Generate an XML document, containing the above data, using a specific schema.
I've been playing around with function module SAP_CONVERT_TO_XML_FORMAT which has the following interface:
CALL FUNCTION 'SAP_CONVERT_TO_XML_FORMAT'
      EXPORTING
      I_FIELD_SEPERATOR    = ''
      I_LINE_HEADER        = ''
        I_FILENAME           = v_fname
      I_APPL_KEEP          = ''
      I_XML_DOC_NAME      = v_docname
      IMPORTING
        PE_BIN_FILESIZE      = v_byte
      TABLES
        I_TAB_SAP_DATA       = i_SapData
      CHANGING
        I_TAB_CONVERTED_DATA = i_XMLData
      EXCEPTIONS
        CONVERSION_FAILED    = 1
        OTHERS               = 2.
I'm uncertain as to whether or not the Export parameter, I_XML_DOC_NAME refers to some schema or definition and therefore have been excluding it. In doing so, the generated XML document seems to use the field name/type information from my itab for the tags.
If this function module requires an XML Document Name, how do I create one and where do I store it in R/3? If this is not the recommended solution, is anyone familiar with a way to load an XML schema, retrieve some data then have SAP generate an XML document using the schema?
Many thanks for any help available.

Hi Geoff,
I would like to generate an XML file which contains data as shown below:
<Insert>
<result>
<type>A</type>
<id>1</id>
<date>11/11/2006</date>
<source>Web</source>
</result>
</Insert>
I'm using the below given query for this purpose:
SELECT XMLQuery('<Insert>

       let $id := $c/ROW/ID/text(),
           $code := $c/ROW/CODE/text(),

<id>{$id}</id>
<date>{$date}</date>

V_Insert stores the required result.
How do I save this result to a XML Document?
Please help.

Generating an xml document from SQLplus

Dear list,
We have over 240 database tables in our tablespace, which we would like to very quickly export to an xml file.
Is there any solution ?
regards
Ben

Are the xml documents stored in a XMLType column?
XMLType tables may be retrieved as XML.
http://www.oracle.com/technology/sample_code/tech/java/codesnippet/xmldb/transformxml/TransformXML.html
For tables with non-XMLType columns retrieve the document with XSU utility.

Generating Nested XML Documents

Hi,
We want to generate nested XML documents from sql queries using pl/sql.
If the output of the query is
EMPNO NAME MGRNO
1 Super Admin 0
2 Mgr1 1
4 SubMgr1_1 2
5 SubMgr2_1 2
3 Mgr2 1
6 SubMgr1_2 3
then XML generated should be in the format
Super Admin
Mgr1
SubMgr1_1
SubMgr2_1
Mgr2
SubMgr1_2
Your early response is appreciated.
Thanks.

No, the id is not unique, it is part of the data. Also, I don't need to update the XML document.
I store the data part (id, status, nodenum) in the "resp" table with a primary key as a combination of id and some other info. The table "nodes" will have a foreign key and multiple occurrences of node. Same with table "restricts" with multiple restrict.
Do I need to create a DOM tree then store each part of the XML into appropriate tables? And how do I do that? (which APIs, etc.)
Thanks,
Thuvan

Generate an XML file from a DOM tree

Hi,
I'm trying to generate an XML file from a DOM tree that I obtained from another XML file with the Xerces library. I used the following operation :
public static void writeXmlFile(Document doc, String filename) {
try {
Source source = new DOMSource(doc);
File file = new File(filename);
Result result = new StreamResult(file);
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(source, result);
} catch (TransformerConfigurationException e) {
System.err.println(e);
System.exit(1);
} catch (TransformerException e) {
System.err.println(e);
System.exit(1);
But I have this Windows/Linux problem. When I execute this on Windows, everything is correct. But if I try on Linux (every distribution does the same thing), I obtain an XML file where everything is written on just ONE LINE : there is neither identation nor carriage return at the end of a line ... And that is pretty annoying 'cause I need to SEE what I generate ...
Thanks for your answer,
Blueberryfin.

Actually I would think that no indents and no new-lines would be more correct, but maybe it's an option for parsers to do it either way if you don't specify it. If you want to specify it, look at this post from last month:
http://forum.java.sun.com/thread.jsp?forum=34&thread=383400

Hi All,
I need help on the following requirement very badly. Pls help me.
I have a requirement to implement with java and XML. I am quit new to XML.Can any of you pls help me.
I have a DTD file. I need to generate XML document from it using java code. I have to use DTD as a template to generate my XML document.
After going through WEB sites, I understtod that, we have to user Java API JAXB for my requirement. But I could not find JAXB.jar anywhere.
I need to know the following inforamtion ....
1. Is my understanding of using JAXB for my requirement is correct?
2. Where can I get JAXB.jar?
3. What are the steps to create XML document from a DTD in Java?
If can give me a sample code for this would help me a lot.
Pls pls reply me. Your help is greatly appreciated.
Thanks in Advance.

Best way to generate the XML files from a DTD file

Hey,
I am writing an application that needs to convert a complicated data structure into an xml file. I have design a DTD file that describes the data structure.
My question is what is the best, most efficient way to covert the data structures (objects) into the XML files with a DTD file.
Thank you very much.
Candy

Convert the DTd to an XML Schema. Generate java classes from Schema with Jaxb. Create an XML document from the java classes.

How do you include a DTD when generating an XML document

Hi
I have just started to use the Java XML Pack to generate a XML document.
How do you put the dtd element
<!DOCTYPE Controller SYSTEM "controller.dtd">
in the generated document.
I am using the following piece of code
public void generate(...)
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.newDocument();
Element rootElement = createElement("Controller");
// Fill out the nodes etc
// Save the result
TransformerFactory tFactory =
TransformerFactory.newInstance();
Transformer transformer = Factory.newTransformer();
File f = new File("dummy.xml");
FileWriter fw = new FileWriter(f);
DOMSource d1 = new
DOMSource(rootElement,"controller.dtd");
StreamResult result = new StreamResult(fw);
transformer.transform(d1, result);
Thanks

Hello,
I had to go through quite some pain to get this done about a year ago,anyways,here is the solution.
all the import files are in jaxp1.1 bundle.
below is a test class code.
import org.apache.crimson.tree.XmlDocument;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import java.io.*;
public class CreateDTDInXMLFile {
public CreateDTDInXMLFile() {
public static void main(String[] args) {
try {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.newDocument();
Element root = document.createElement("root");
Element name = document.createElement("name");
name.appendChild(document.createTextNode("Khalid"));
Element address = document.createElement("address");
address.appendChild(document.createTextNode("2022 11th Ave SW"));
root.appendChild(name);
root.appendChild(address);
document.appendChild(root);
((XmlDocument)document).write(System.out);
//the above will print the simple xml doc,now add the dtd
//suppose the dtd is [<!DOCTYPE root SYSTEM "address.dtd">]
((XmlDocument)document).setDoctype(null,"address.dtd",null);
//now print the xml doc again
System.out.println("\n");
((XmlDocument)document).write(System.out);
} catch(ParserConfigurationException pce) {
pce.printStackTrace();
return;
}catch (IOException ioe) {
ioe.printStackTrace();
This will take care of the agony..

GetXMLSchema java method generates invalid XML Schema document

Hi all,
I managed to get the xdk FAQ demo to work eventually on oracle 9.2.0.1.0 for windows, I noticed however that when I generate an XML Schema definition against a query, the document contains an outdated namespace declaration (minor flaw) and "nullable" attributes instead of "nillable", resulting in an invalid XML Schema document when edited with certain tools like Altova's XmlSpy.
How can I fix this?
See below for the XML Schema source.
Bye,
Flavio
<xsd:schema xmlns:xsd="http://www.w3.org/2000/10/XMLSchema">
<xsd:element name="ROWSET">

<xsd:complexType>
<xsd:sequence>
<xsd:element name="CATEGORY" type="xsd:string" minOccurs="0"/>
<xsd:element name="QUESTION" type="xsd:string" minOccurs="0"/>

</xsd:sequence>
<xsd:attribute name="num" type="xsd:integer"/>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>

With my (trial) copy of XMLSPY (version 2004 rel.3), I get following pop-up when opening that schema:
"This schema is written in an old standard:
http://www.w3.org/2000/10/XMLSchema
Do you want XMLSPY to convert it to the new one:
http://www.w3.org/2001/XMLSchema"
When I click "Yes" and save, I get a perfectly valid schema (with nullable replaced by nillable).

Is it possible in java 5 to generate a XML document from object?
