Converting EJB Object into XML

All:
Suppose I have an EJB that is named MyDog, it has attributes as follows:
name
breed
weight
age
Is there a way to convert this Object into an XML document? Something like:
<?xml version=\"1.0\" ?>
<MyDog>
<name>Bubba</name>
<breed>Australian Shepherd</breed>
<weight>65 lbs</weight>
<age>6 years old</age>
</MyDog>
I can't find any information on doing this - any ideas, links, etc? There has to be a way to do this, but I can't find it. I'm welcome to any ideas out there!

check JAXB - might be usefull for you: http://java.sun.com/xml/jaxb/index.html

  • Converting Document object into XML file

    I was wondering how to convert a document object to XML file? I have read the documentation about document and Node but nothing explains the procedure of the conversion. Ive been told that it can be done, but not sure how. I have converted an XML file into Document by parsing DocumentBuilder. Just not sure how to do the reverse. Any help appreciated.

    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer trans = tf.newTransformer();
    trans.transform(new DOMSource(yourDOMsRootNode), new StreamResult(new FileOutputStream(yourFileName)));or something a lot like that.

  • How can I convert table object into table record format?

    I need to write a store procedure to convert table object into table record. The stored procedure will have a table object IN and then pass the data into another stored procedure with a table record IN. Data passed in may contain more than one record in the table object. Is there any example I can take a look? Thanks.

    I'm afraid it's a bit labourious but here's an example.
    I think it's a good idea to work with SQL objects rather than PL/SQL nested tables.

  • WD(ABAP) - How to convert PDF object to XML

    I know there is a way available to converting PDF object to XML in JAVA. However how to achieve this goal in ABAP?
    In Web Dynpro ABAP, I can bind a context attribute to the pdfSource property of interactive form element. There also should be method to able to convert the binary content of this attribute to XML format, right? Does anyone know it?
    Your help would be greatly appreciated.

    Hi all,
    As an extension to Fred's question, is it possible to later use the generated XML data and present it in a PDF template?  It used to be possible using the FDF format, but Adobe seem to have discontinued that. 
    My basic requirement is to send the form data to a third party in XML format and for them to be able to view it in human-readable format, preferably using a PDF as a template. 
    Is this possible?
    Thanks,

  • Converting webi reports into Xml

    Hi all ,
    Can we convert the BO Edge 3.1 Webi reports into XML Format?
    Pls suggest me a solution and if we can convert, pls describe the procedure to be followed inorder to convert the reports into xml files?
    Thanks in advance,
    Thanks & regards,
    Amrita.B

    Hello,
    While this is not possible (directly) for the entire report, you could do one of the following:
    1. If you're on SP2 (or higher), you could publish Webi Report Content as a web service. There is more information in the pdf at http://help.sap.com/businessobject/product_guides/boexir31SP2/en/xi31_sp2_webi_rich_en.pdf (pg 304) .
    2.  Use QAAWS to publish queries used in the report as web services.

  • Convert gzip files into XML format

    We have a requirement where we receive gzip files. These files are zipped file containing base64 binary format csv files. We would have to convert these files into XML format. Please let me know any of the following.
    1. Is there any Xpath query or XSL function (somthing similar like doTranslateFromNative() ) to convert from gzip files to XML format.
    2. If we need to unzip the zipfile outside fusion, then java code piece to unzip the gzip file. I guess after that we can use the usual doTranslateFromNative() function to translate to XML format, since after unzipping the gzip file, they are base64 binary formats.
    Thanks in advance,
    Toms

    There is an option to do pre-processing and post processing of Files when using File adapter. You need to create a valve which will first do pre processing and send the output to FileAdapter.
    You can get more information here:
    http://docs.oracle.com/cd/E23943_01/integration.1111/e10231/adptr_file.htm#CACDHGGG
    under section: 4.2.14 Pre-Processing and Post-Processing of Files
    Essentially you will use Java to unzip the file first and then the unzipped content will be passed to the adapter.

  • How to convert .stl file into .xml file. Subtitles to IMPORT INTO FCPro

    I have a subtitles file which was created in dvd studio pro. I exported that file and made a .stl file (which can be opened with TextEdit).
    I need to import that file into FCP to then make a quicktime file w/subs to be exported.
    I'm trying to use TitleExchange which tells you you CAN convert .stl files into .xml (FCPro type of file) but when I try to import the .stl subtitle file into TitleExchange to be converted to .xml I get the following error:

  • Convert jsp page into xml  or dom for search

    Hello everyone,
    I have to build an application that searches for message beans in all jsp page. I did it the traditional way, using scanner and string methods. Its working but its not perfect. So i want to convert all my jsp page into xml format and then process them. My jsp pages are quite complicated. I used some jars that convert them into jspx . But its not working. Please help
    Thanks in advance

    Well its like this.I need to develop a program that reads all the message bean keys.. We have lots of struts webapps. All messages in the jsp pages have been externalised and internationalised. Now i have to build a program that given a webapp path prints out all the message bean keys used in the webapp. I have developed the program using the Plexus Directory scanner to filter all the jsp pages and java util Scanner to read line by line and used String functions to search for keys.
    Now thats not the best soultion. The best way, imo, is to cinvert the jsp into xml pages and then we can parse the xml pages easily. The' problem is to find a way to convert the jsp pages(jstl +javascript) into xml.
    Can you help me out?
    Thanks

  • Convert an Object into a String

    Good day to everyone. I am trying to do a little coding in which a user will input his desired username. I want to check the database if the desired username of the current user is existing, so there'll be no duplication. I'm using JPA for the model and JSF for the controller and view.
    Here's my Model.
    @Entity
    public class WebUser implements Serializable {
        private static final long serialVersionUID = 1L;
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        private Long id;
        private String lastName;
        private String firstName;
        private String middleName;
        private String username;
        private String password;
        public Long getId() {
            return id;
        public void setId(Long id) {
            this.id = id;
        @Override
        public int hashCode() {
            int hash = 0;
            hash += (id != null ? id.hashCode() : 0);
            return hash;
        @Override
        public boolean equals(Object object) {
            // TODO: Warning - this method won't work in the case the id fields are not set
            if (!(object instanceof WebUser)) {
                return false;
            WebUser other = (WebUser) object;
            if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
                return false;
            return true;
        @Override
        public String toString() {
            return "web.model.WebUser[id=" + id + "]";
        public String getLastName() {
            return lastName;
        public void setLastName(String lastName) {
            this.lastName = lastName;
        public String getFirstName() {
            return firstName;
        public void setFirstName(String firstName) {
            this.firstName = firstName;
        public String getMiddleName() {
            return middleName;
        public void setMiddleName(String middleName) {
            this.middleName = middleName;
        public String getUsername() {
            return username;
        public void setUsername(String username) {
            this.username = username;
        public String getPassword() {
            return password;
        public void setPassword(String password) {
            this.password = password;
    }The controller and jsp are auto-generated from Netbeans. My question is, how will I convert the 'WebUser' object into a String so I can compare the value from input text to the value in the database?
    Here is my validation method inside WebUserController.java
    public void validateUsername(FacesContext facesContext, UIComponent component, Object value) throws ValidatorException {
            String newUsername = (String) value;
            System.out.println("new user name: " +newUsername);
            System.out.println("component: " +component);
            int webUserSize;
            StringBuffer sb = new StringBuffer();
            //webUsers.toString();
            if ((webUsers == null) || (webUsers != null)) {
                System.out.println("web users null");
                List<WebUser> allWebUsers = getWebUsers();
                webUserSize = allWebUsers.size();
                System.out.println("all web users: " +allWebUsers);
                System.out.println("size " +webUserSize);
                for(int i=1; i<=webUserSize; ++i) {
                    sb.append(allWebUsers);
                    System.out.println("username: " +sb.append(allWebUsers));
            }Honestly I'm new to java and having a hard time with this one. Hope someone can help me. Thanks a lot.
    I know my code is a mess. :(

    Thanks for the help guys! I used the "unique constraint" annotation of JPA and my problem is solved.
    Here's the code:

        uniqueConstraints={@UniqueConstraint(columnNames={"username"})}
    public class WebUser implements Serializable {

        private String lastName;
        private String firstName;
        private String middleName;
        private String username;
        private String password;
        public Long getId() {
            return id;
        public void setId(Long id) {
            this.id = id;
        @Override
