Converts a VARRAY object into a BLOB

Hi
Is it possible to convert a VARRAY collection into a BLOB?
Kind regards
Taoufik

Yes.
I would expect that the functionality in UTL_RAW
http://www.psoug.org/reference/utl_raw.html
might be helpful in doing so.

API for converting a Java object into XML?

Do you know of any Java API that I could use to convert a Java
object into its equivalent XML representation?
For example if I have a class called "Foo" with variables va, vb
and I have an instance of Foo with va having the value 1 and vb
having the value 2, I would like be able to generate the
following XML fragment:
<Foo>
<va>1</va>
<vb>2</vb>
</Foo>
Thanks,

Converting the scanner object into string object....

Hello everyone. I've finished my hw and one thing made me curious about it. I hope you can help me. Now, I've tried to make this code in NetBeans IDE 6.0:
Scanner src = new Scanner(System.in);
String s = src.toString().toLowerCase(Turkish /* locale thing*/);
My purpose is to take users entries to console as string and than make the letters in lower case. But, my language is turkish. So I've problem with it because there is no Locale Turkish object in IDE.
So what do you suggest. Do you know a downloadable or updatable solution for this. Or if you're sure that there is no prepared solution, what do you suggest.

I've looked that page but I've found some of the answers at http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html#toLowerCase(java.util.Locale)
I knew that I can't write a code like that. I was just wondering if I could change the locale (after I initialize the string obj.) while toLowerCase().
I needed that becouse when I want to ask a question at console: I must ask it in whatever user's language is. And also get the answers in their own language. Then I'll match the answers with my answers. for example console will ask:
please enter your language? T?rk?e, English, Dutch, ?vrit, ...
and the user will enter some characters to chose their language IN THEIR OWN ALPHABET that I'll match those with the ones that I created the answers (inside the codes) in all languages.
If there is a match the program will work with that alphabet.
I was asking for an easier way to get on with this. There may be a class that I can reach any kind of alphabets. or a method maybe.

Converting Dom Document object into XML file removes the DTD

Hi All
My xml is dtd. I have one xml file. i changed the node value after that i want to create a xml file with the same name. I created new xml file but i am not seeing the old dtd in the new file. This process is done with the help of jaxp.
My code is given below
File fileInput = new File("input.xml");
          File fileOutput = new File("output.xml");
          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          factory.setExpandEntityReferences(false);
          DocumentBuilder builder = factory.newDocumentBuilder();
          Document document = builder.parse(fileInput);
          TransformerFactory tFactory = TransformerFactory.newInstance();
          Transformer transformer = tFactory.newTransformer();
transformer.setOutputProperty(javax.xml.transform.OutputKeys.INDENT, "true");
          transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
          DOMSource source = new DOMSource(document);
          FileOutputStream fos = new FileOutputStream(fileOutput);
          StreamResult result = new StreamResult(fos);
          transformer.transform(source, result);
Thanks in advance

The Transformer API does not guarantee the preservation of that information. You may want to check the DOM L3 Load/Save package (http://java.sun.com/javase/6/docs/api/index.html). Alternatively, you may force things by setting the additional output properties 'doctype-public' and 'doctype-system'.

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:
@Entity
@Table(
    name="WebUser",
    uniqueConstraints={@UniqueConstraint(columnNames={"username"})}
public class WebUser implements Serializable {
    private static final long serialVersionUID = 1L;

    @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 + "]";
        return "web.model.User[username=" + username +"]";
    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;

How do i convert an image object to a byte array ?

Hi
how do i convert an image object into a byte array
early reply apperciated

Oh sorry my method and the other method need to have the pixels from the Image passed to them which you get my using pixelgrabber:
//create width and height variables from image
          int w = img.getWidth(this);
          int h = img.getHeight(this);
          //retrive picture from image
          int[] pix = new int[w * h];
          PixelGrabber pg = new PixelGrabber(img, 0, 0, w, h, pix, 0, w);
          try{ pg.grabPixels();
          } catch (InterruptedException ioe) {
               System.err.println("Interrupted");
          if ((pg.getStatus() & ImageObserver.ABORT) != 0) {

SAP objects into Webservices

Hello Experts,
Can anybody guide me to explain how to convert the SAP objects into webservices.
For example, convert Leads in SAP to be exposed as webservices.
Thanks,
Vijay

Hello,
Quick answer to find the standard services without J2EE Engine or XI there is a BSP application that can be used to list the Web Services.
http://<host_name>:<port_number>/sap/bc/bsp/sap/WebServiceBrowser/search.html?sap-client=<relevant_client>
See this link: [Generating WSDL in SAP WebAS|http://help.sap.com/saphelp_webas620/helpdata/en/94/f8c8c8e68811d6b2dc00508b5d5211/content.htm]
Detailed answer
Classical way of creating Web services in ABAP stack is easy. If you are familiar with SAP RFC (Remore Function Calls), every RFC enabled Function Module can be "published" as a web service. The trick is the SOAP (runtime) service available since WAS 6.20. See the [Basic Concepts of SAP SOAP runtime|http://help.sap.com/saphelp_webas620/helpdata/en/94/f8c8a2e68811d6b2dc00508b5d5211/content.htm] here.
So, literally you don't have to anything to "generate" web services for "standard objects" - if BAPIs and RFC enabled FMs are those standard objects you are looking for.
To enable the use of Web Services in external tools, a description of the interface must exist in the Web Service Description Language WSDL. - This is common knowledge right?
In the SAP Web AS, you can generate these descriptions using the Web Service Browser, which is a BSP application.
You can access the Web Service Browser using the URL:
http://<host_name>:<port_number>/sap/bc/bsp/sap/WebServiceBrowser/search.html?sap-client=<relevant_client>
Trick to find the <host_name>, <port_number> and <relevant_client>:
You can determine values of host_name and port_number in transaction SMICM (choose GoTo -> Services or Shift - F1.
Hope this is very useful.

Conver String object into char

Hi friends,
I don't know how convert the String object into char(Primitive data type), using wrapper class?
Kindly let me know.

Have a look in the String API documentation for a method that returns an array of char.
(It's not really what most people would describe as a wrapper class: that's more like converting a single char into an instance of Character.)

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.

Error : while converting a WD ABAP object into SAP Transaction

Hi,
I am trying to converting a WD ABAP object into SAP Transaction but i am getting the following error while executing the transaction :
Network Access Message: The page cannot be displayed

This seems to be your specific network configuration. It seems that your corporate network is blocking HTTPS requests which don't use port 443. Your ABAP system is configured to use a port other than 443. Either talk to your basis admins about changing your ABAP system configuration to use port 443 or talk to your network administrators to allow whichever port the ABAP system is running on.
