Writing XML file using javax.xml package

I am writing an XML file with the foll piece of code:
public static void writeXmlFile(Document doc, String filename) {
try {
// Prepare the DOM document for writing
Source source = new DOMSource(doc);
// Prepare the output file
File file = new File(filename);
Result result = new StreamResult(file);
// Write the DOM document to the file
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(source, result);
} catch (TransformerConfigurationException e) {
} catch (TransformerException e) {
In this case above, the whole Document has to be passed to create a new DOMSource. is there any way where in I can pass the individual Nodes to the DOMSource ?
I want the Nodes to be written one by one as writing the whole document is giving me a OutOfMemoryError (I have about a million records to be written in the XML file).
Any help would be greatly appreciated

XML validation using javax.xml.validation

Hello,
I am trying to validate some xml against my xsd.
Here is my xml:
<host>
    <status>Unknown</status>
</host>Here is my xsd:
<?xml version="1.0"?>
                                                                                                                                                             <xsd:schema targetNamespace="blah"

</xsd:restriction>
</xsd:simpleType>
<xsd:element name="host">

     <xsd:all>
       <xsd:element name="status" type="tns:Status"/>
     </xsd:all>

                                                                                                                                                             </xsd:schema>My test code is:
        try
            DocumentBuilder parser = DocumentBuilderFactory.newInstance().newDocumentBuilder();
            Document document = parser.parse(new File("test.xml"));
            // Create a SchemaFactory capable of understanding WXS schemas.
            SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
            // Load a WXS schema, represented by a Schema instance.
            StreamSource schemaFile = new StreamSource(new File("schema.xsd"));
            Schema schema = factory.newSchema(schemaFile);
            // Create a Validator object, which can be used to validate the document
            Validator validator = schema.newValidator();
            // Validate the DOM tree.
            validator.validate(new DOMSource(document));
        catch(Exception e)
            fail("XML validation failed: " + e.getMessage());
        }I get the following error:
ERROR: 'cvc-elt.1: Cannot find the declaration of element 'host'.'
If i replace "type=tns:Status' in the "status" element with just "type=string", it works fine.
Does anyone have any idea what the problem is?
Thank you,
David

To daft_davy:
1. Your XSD document is invalid: the xmlns attribute of schema documents must always have the following value: "http://www.w3.org/2001/XMLSchema"
All other values will result in the following validation error:
org.xml.sax.SAXParseException: s4s-elt-schema-ns: The namespace of element 'schema' must be from the schema namespace, 'http://www.w3.org/2001/XMLSchema'.
Your XSD should look like this:
<?xml version="1.0"?>
<xsd:schema targetNamespace="blah" xmlns:tns="blah" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:simpleType name="Status">
    <xsd:restriction base="xsd:string">
      <xsd:enumeration value="Unknown"/>
    </xsd:restriction>
</xsd:simpleType>
<xsd:element name="host">
    <xsd:complexType>
      <xsd:all>
        <xsd:element name="status" type="tns:Status"/>
      </xsd:all>
    </xsd:complexType>
</xsd:element>
</xsd:schema>2. Your XML document does not match the XSD schema (even if you use the one above) for the following reasons:
a) The root element of the XML document must be associated with the namespace defined by the targetNamespace attribute of the schema.
b) The "blah" namespace at the element <status> in the XML document has to be undeclared because there is no namespace declaration to this element in the schema document either. There are to ways to do this:
<host xmlns="blah">
<status xmlns="">Unknown</status>
</host>or:
<xxx:host xmlns:xxx="blah">
<status>Unknown</status>
</xxx:host>
To watertownjordan:
The namespace URI can be virtually any string, so you don't need to specify a valid URI to define a namespace.

Creating XML File Using xmldom Package

How can I create an XML file from scratch using the PL/SQL xmldom package?
I want to create an XML file using the xmldom package instead of building the individual tags as strings of VARCHAR2 character data. There is quite a bit of documentation regarding manipulating input XML files using DOM -- but not for creating XML files from scratch given known "tagnames" (<lastName>) and retrieved database "values" ("Smith").
<person>
<lastName>Smith</lastName>
</person>
Is there any documentation that you can recommend?
Thank you.

Here is an example.
The create_file procedure creates the file.
The other procedures are generic procs that can be used with any XML.

"encoding = UTF-8" missing while writing XML file using file Adapter

Hi,
We are facing an unique problem writing xml file using file adapter. The file is coming without the encoding part in the header of xml. An excerpt of the file that is getting generated:
<?xml version="1.0" ?>
<customerSet>
<user>
<externalID>51017</externalID>
<userInfo>
<employeeID>51017</employeeID>
<employeeType>Contractor</employeeType>
<userName/>
<firstName>Gail</firstName>
<lastName>Mikasa</lastName>
<email>[email protected]</email>
<costCenter>8506</costCenter>
<departmentCode/>
<departmentName>1200 Corp IT Exec 8506</departmentName>
<businessUnit>1200</businessUnit>
<jobTitle>HR Analyst 4</jobTitle>
<managerID>49541</managerID>
<division>290</division>
<companyName>HQ-Milpitas, US</companyName>
<workphone>
<number/>
</workphone>
<mobilePhone>
<number/>
</customerSet>
</user>
So if you see the header the "encoding=UTF-8" is missing after "version-1.0".
Do we need to configure any properties in File Adapter?? Or is it the standard way of rendering by the adapter.
Please advice.
Thanks in advance!!!

Problem writing xml file using DOM

Hi,
I am trying to write a xml file using DOM. I am using xalan 2.5, xerces 1.4.4, jdk 1.3.1 in JRun 3 on windows.
The code where I get exception :
               TransformerFactory tFactory = TransformerFactory.newInstance();
               Transformer transformer = tFactory.newTransformer();
               transformer.transform(new DOMSource(doc), new StreamResult("pr.xml"));
I get the runtime error as follows:
javax.servlet.ServletException: null
java.lang.NoSuchMethodError
     at org.apache.xml.utils.DOM2Helper.getNamespaceOfNodeDOM2Helper.java:342)
     at org.apache.xml.utils.TreeWalker.startNode(TreeWalker.java:387)
     at org.apache.xml.utils.TreeWalker.traverse(TreeWalker.java:202)
     at org.apache.xalan.transformer.TransformerIdentityImpl.transform(TransformerIdentityImpl.java:343)
Thinking it is because of classpath, I placed xalan 2.5, xerces 1.4.4 jar files in jrun admin lib directory and in server lib directory as well. Still getting the same error.
Any suggestion?
Thanks in advance

xalan is included in JRun 4. However JRun 3 does not.
However I tried with the same code in JRun3 in different system. The error is completely different. I understand this is because of different version of files. trying to solve ;)

You should update your DOM document to represent the changes that you want made.
Then, using the Transformation API you simply transform your document onto a stream representing your file. Something like this:
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
// TODO - set indentation amount!
Source source = new DOMSource(dom);
Result result = new StreamResult(file);
transformer.transform(source, result);Hope this helps.

How to write as XML file using java 1.5

hi all,
i am trying to create an XML file using java 1.5. I took a XML creating java file which was working with java 1.4 and ported same file into java 1.5 with changes according to the SAX and DOM implmentation in java 1.5 and tried to compile. But while writing as a file it throws error "cannot find the symbol."
can any body help me out to solve this issue.......

//error is occuring here Since write method is not available in the Document class
xmlDoc.write(outf);
outf.flush();

Hi,
when I look in the JDK1.4.2 specification I don't see any write method in the Document interface.
However, your solution is the Transformer class. There you transform your DOM tree into any output you need. Your code sould look something like this:     TransformerFactory tf = TransformerFactory.newInstance();
     // set all necessary features for your transformer -> see OutputKeys
     Transformer t = tf.newTransformer();
     t.transform(new DOMSource(xmlDoc), new StreamResult(file));Then you have your XML file stored in the file system.
Hope it helps.

Error while encrypting the xml file using asymmetric cipher...pls help

i am encryption the xml file using asymmetric cyper....
in one class , i am generating private key and public key using "RSA" algorithm..using 1024 byte initialization...
it is generating properly...
and after that in second class i am encrypting the xml file using "DESede" algorithm and i am using public key of above class..
but i am getting exceptione :
java.security.InvalidKeyException: Invalid key length: 162 bytes
at com.sun.crypto.provider.DESedeCipher.engineGetKeySize(DashoA6275)

at demoXmlEncApp.simulateBookSellersEnd(demoXmlEncApp.java:72)
at demoXmlEncApp.main(demoXmlEncApp.java:29)
so, what is that ?
i want to use RSA algo for key generatiion and DESede for cipher initialization .
is there any site for where source code of xml file encryption using asymmetric cipher is available?
pls, help me.....

Sachin,
What sabre150 is trying to explain to you, is that encrypting data (such as an XML file) is a 2-step process. In the first step, you generate a symmetric key (such as DES, 3DES, AES) and encrypt your file with this key (and the appropriate mode and padding).
In order to ensure that your encrypted data cannot be decrypted by unauthorized individuals, you now need to protect the symmetric key. Encrypting your symmetric key with another symmetric key does not solve the problem, since you have a chain of symmetric keys that need to be encrypted into infinity.
Cryptographers solve this problem by encrypting the symmetric key with an asymmetric key, such as as RSA. To perform this second step, you generate an RSA key-pair, encrypt the symmetric key you generated in step 1 with the Public key of the RSA key-pair, and give the recipient of the encrypted XML file, access to the Private key of the RSA key-pair as well as the encrypted symmetric key.
The recipient, then uses the RSA Private key to decrypt the symmetric key first, and then uses the "plaintext" symmetric key to decrypt the XML file.
What sabre150 was also attempting to explain to you, is the traditional way of transporting an encrypted "blob" that consists of data + symmetric key. With a modern key-management system, combining the two would be unnecessary.

          XPath xpath = XPathFactory.newInstance().newXPath();
          NodeList nodes = (NodeList)xpath
               .evaluate("//stud_name[text()='Suresh']", doc, XPathConstants.NODESET);
          // Rename these nodes
          for (int idx = 0; idx < nodes.getLength(); idx++) {
               nodes.item(idx).setTextContent("Suresh-Renamed");

Procedure for read/write an XML-File using UCCX9

Hi Team!
Is there someone who can explain me the procedure of reading/writing an XML-File using Cisco UCCX Rel. 9.0?
In the last couple of days I did a lot of research on the partner community as well as reading the CRS-Editor-PDFs.
But I can’t find a solution.
There are some templates available but they all didn’t seem to work.
I have two xml-files, both uploaded to “Document Management\en_us\”.
The script itself is attached to this posting.
I build that my script according to a sample script I found in the community.
From my point of view I have configured my script exactly like the sample script.
But it still doesn’t work.
I am especially interested in where to store the the appropriate files.
I would be very happy if there is someone who can explain me, what’s wrong there.
Many thanks in advance.
Kind regards
Michael

I'm experiencing the same issue [reading XML causes errors that say things from "no such file" to some odd Java exception.] I'm able to use a template XML file and after authenticating a user, transform the template into a proper XML file and then successfully save it to the en_US Doc Repository with updated values.
However, no matter what I've tried or who I've asked, the READ on the XML file so that I can actually script something that does some routing based on the value of the XML file created in my first script? Ultra fail.
I've even worked with three separate TAC IPCC engineers who were able to reproduce the issue in their test environment, but they were unable to assist. Eventually, whe pressed, I received this response from the last IPCC engineer.:
"Hello Brad,
Yes I know what I provided you with is what you already have achieved and this missing step is precisely what you need: how to setup the script to check the status and value of this XML document and then decide routing according to the state. But unfortunately this is what I found internally. The other resources are the ones you already know: support forums, scripting guides. The other resource with suggest to customer looking for script assistance is the Cisco Account Manager of your company, they know where to get the resources for such issues. Then again as I mentioned before on our phone conversation TAC does not support scripting but certainly if I find something else on my side I will let you know for sure."
I would do ponderous cartwheels of joy if someone who has this working in version 9.x [9.0.2 specifically] could share the deep magic.

Retrieve and Read XML Files using Oracle6i Forms

Dear all .. i have some problem here: How can i retrieve and read a XML files using Oracle6i Forms? What should i do? Thanks - ASAP -

Several ways - Pick up a copy of the Oracle XDK off of OTN. This provides Java and PL/SQL toolkits for dealing with XML files.
The PL/SQL one would be in the Database, so you might have to use the Java one of you need to do it on the Forms machine.
You can use the Java Importer in 6i to create PL/SQL wrappers that you can call from forms into the Java XDK APIs.
Or of course you can just use the TEXT_IO package to read the XML as a text stream and parse it in your own PL/SQL code...

Updating XML file using GUI

Hi
I have created a java class that uses JButton to bring up JFileChooser. I then select a file and add the file details to a xml file. below is the code showing how I capture this information and add to xml:
if(file != null && state==JFileChooser.APPROVE_OPTION)
                         String name= file.getName();
                         String directory = file.getPath();
                         long length = file.length();
                         // convert file length into
                         long kb= length/1024;
                         String s= new String();
                         String a=s.valueOf(kb);
UploadFiles uploadFiles = new UploadFiles();
                    uploadedFiles.addFileElement(name,directory,a);
addFileElement(...) is a method that add the above information to xml file. however, when I select a file, the file details are not added to the xml file; and i also get some errors.
But I know that my addFileElement(..) method is correct since if I use the following code , I am able to write to a xml file:
uploadedFiles.addFileElement("xml.java","directory","size");
So does anyone know why my addFileElement(...) is not working properly.
thanks
Qasim

Below is my code for addFileElement method.First of all I was using DOM, but since this method was not working properly I switched to JDOM. I wrote the same code in Jdom, and now it is working.
public void addFileElement(String name, String directory, String size)
          this.name=name;
          this.directory=directory;
          this.size=size;
          //create a file element to hold information about a file
          Element fileElement=document.createElement("file");
          //create attributes for name
          Attr nameAtt = document.createAttribute("name");
          nameAtt.setValue(name);
          //set directory attribute
          Attr directoryAtt = document.createAttribute("directory");
          directoryAtt.setValue(directory);
          //size attribute for the file
          Attr sizeAtt = document.createAttribute(size);
          sizeAtt.setValue(size);
          //add teh above attributes to the file element
          fileElement.setAttributeNode(nameAtt);
          fileElement.setAttributeNode(directoryAtt);
          fileElement.setAttributeNode(sizeAtt);
          //decide where we want to put this element. first get the 'files' element reference and insert this new element after it.
          NodeList newfile = document.getElementsByTagName("file");
          Element firstFile=(Element)newfile.item(0);
          firstFile.getParentNode().insertBefore(fileElement, firstFile);
          try
               ((XmlDocument) document).write(new FileOutputStream("UploadedFiles.xml"));
          catch (IOException io)
               System.err.println("Problem with writing to file " );
               io.printStackTrace();
