Java object printing

Hi,
I am printing a java object for e.g:
Object o="{27-01-1989}";
System.out.println("date="+o);
In this snippet,it prints "date={27-01-1989}"
For this how to ignore these curly braces.

I am returning a class. It returns like that only.No, you're returning an object. You can't return classes, they're an abstract concept.
What is the actual class of your object? Is it Date? If yes, then use SimpleDateFormat to format it to your liking.
If it's something else, look into the substring() methods of String.

Printing pdf's from a Java object

I have a java object that puts the pdf's in an array to print. The array is in the correct order, however the printing is priting the pdf's in the order of Time First Received. Is this a problem with Acro Reader and is there a fix for it, or is this problem something else?

How are you printing the pdf's?

Problem in java.awt.print

Hi here is my code .
I am generating page dynamically and passing to printer.
Printing Functionalities working file. But I am taking some data from database (Access). And in this code for example i have 4 records in Database and i am generating 4 pages (each page for resord).
I am getting only 2 records. And for other two records i am getting blank page.
Reason is My ResultSet object is moving to next record twice.
I mean if i have 6 records i get only 3 pages.
If i have 10 records i get only 5 pages and If i have 1 record i dont get any page.
How shall i solve this problem.
Thanx in advance.

Parse of a xml file to an java object model

Hello,
I'm trying to do a program that receive an xml file and ought to create all the neccesary java objects according to the content of the parsed xml file.
I've all the class created for all the objects that could be present into the xml and the idea is to go down in the tree of nodes recursively until it returns nodes more simple. Then, I create the last object and while I come back of the recursively calls, I create the objects more complex until I reached to the main object.
Until now, I have part of this code, that is the one wich have to parse the parts of the xml.
public static void readFile(String root){
          DocumentBuilderFactory factory = DocumentBuilderFactory
               .newInstance();
          try {
               DocumentBuilder builder = factory.newDocumentBuilder();
               Scanner scanner = new Scanner(new File(root)).useDelimiter("\\Z");
               String contents = scanner.next();
               scanner.close();
               Document document = builder.parse(new ByteArrayInputStream(contents.getBytes()));
               Node node = null;
               NodeList nodes = null;
               Element element = document.getDocumentElement();
               System.out.println(element.getNodeName());
               NodeList subNodes;
               NamedNodeMap attributes;
               //if (element.hasAttributes())
               visitNodes(element);
          } catch (ParserConfigurationException e) {

          } catch (SAXException e) {

                    System.out.println("Document node Name " + childNode.getNodeName());
                    visitNodes(childNode);
               }else if (childNode.getNodeType() == childNode.ELEMENT_NODE){

               }else if (childNode.getNodeType() == childNode.TEXT_NODE && !childNode.getNodeValue().contains("\n\t")){
                    System.out.println("Node value " + childNode.getNodeValue());

               System.out.print(node.getNodeName() + " ");
               System.out.print(node.getNodeValue() + " ");
              }I don't know the use of childNodeType. For example, I expected that the XML tags with childs in his structure, enter by the option NODE_DOCUMENT and the tags without childs by the ELEMENT_NODE.
But the most important problem I've found are the nodes [#text] because after one ELEMENT_NODE I always found this node and when I ask if the node hasChilds, always returns true by this node.
Has any option to obtain this text value, that finally I want to display without doing other recursively call when I enter into the ELEMENT_NODE option?
When one Node is of type DOCUMENT_NODE or DOCUMENT_COMMENT? My program always enter by the ELEMENT_NODE type
Have you any other suggestions? All the help or idea will be well received.
Thanks for all.

Hello again,
My native language is Spanish and sorry by my English I attemp write as better I can, using my own knowledge and the google traductor.
I have solved my initial problem with the xml parser.
Firstly, I read the complete XML file, validated previously.
The code I've used is this:
public static String readCompleteFile (String root){
          String content = "";
          try {
               Scanner scanner = new Scanner(new File(root)).useDelimiter("\\Z");
               content = scanner.next();
               scanner.close();
          } catch (IOException e) {
               e.printStackTrace();
          return content;
     }Now, I've the file in memory and I hope I can explain me better.
I can receive different types of XML that could be or not partly equals.
For this purpose I've created an external jar library with all the possible objects contained in my xml files.
Each one of this objects depend on other, until found leaf nodes.
For example, If I receive one xml with a scheme like the next:
<Person>
    <Name>Juliet</Name>
    <Father Age="30r">Peter</Father>
    <Mother age="29">Theresa</Mother>
    <Brother>
    </Brother>
    <Education>
        <School>
        </school>
    </education>
</person>
<person>
</person>The first class, which initializes the parse, should selecting all the person tags into the file and treat them one by one. This means that for each person tag found, I must to call each subobject wich appears in the tag. using as parameter his own part of the tag and so on until you reach a node that has no more than values and or attributes. When the last node is completed I'm going to go back for completing the parent objects until I return to the original object. Then I'll have all the XML in java objects.
The method that I must implement as constructor in every object is similar to this:
public class Person{
final String[] SUBOBJETOS = {"Father", "Mother", "Brothers", "Education"};
private String name;
     private Father father;
     private Mother mother;
     private ArrayList brothers;
     private Education education;
     public Person(String xml){
       XmlUtil utilXml = new XmlUtil();
          String xmlFather = utilXml.textBetweenXmlTags(xml, SUBOBJETOS[0]);
          String xmlMother = utilXml.textBetweenXmlTags(xml, SUBOBJETOS[1]);
          String xmlBrothers = utilXml.textBetweenMultipleXmlTags(xml, SUBOBJETOS[2]);
          String xmlEducation = utilXml.textBetweenXmlTags(xml, SUBOBJETOS[3]);
          if (!xmlFather.equals("")){
               this.setFather(new Father(xmlFather));
          if (!xmlMother.equals("")){
               this.setMother(new Father(xmlMother));
          if (!xmlBrothers.equals("")){
            ArrayList aux = new ArrayList();
            String xmlBrother;
            while xmlBrothers != null && !xmlBrothers.equals("")){
              xmlBrother = utilXml.textBetweenXmlTags(xmlBrothers, SUBOBJETOS[2]);
              aux.add(new Brother(xmlBrother);
              xmlBrothers = utilXml.removeTagTreated(xmlBrothers, SUBOBJETOS[2]);
            this.setBrothers(aux);
          if (!xmlEducation.equals("")){
               this.setEducation(new Father(xmlEducation));
}If the object is a leaf object, the constructor will be like this:
public class Mother {
     //Elements
     private String name;
     private String age;
     public Mother(String xml){
          XmlUtil utilXml = new XmlUtil();
          HashMap objects = utilXml.parsearString(xml);
          ArraysList objectsList = new ArrayList();
          String[] Object = new String[2];
          this.setName((String)objects.get("Mother"));
          if (objects.get("attributes")!= null){
               objectsList = objects.get("attributes");
               for (int i = 0; i < objectsList.size();i++){
                 Object = objectsList.get(i);
                 if (object[0].equals("age"))
                   this.setAge(object[1]);
                 else
     }Each class will have its getter and setter but I do not have implemented in the examples.
Finally, the parser is as follows:
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.HashMap;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

public class XmlUtil {

          HashMap objet = new HashMap();
          DocumentBuilderFactory factory;
          DocumentBuilder builder;
          Document document;
          try{
               if (content != null && !content.equals("")){
                    factory = DocumentBuilderFactory.newInstance();
                    builder = factory.newDocumentBuilder();
                    document = builder.parse(new ByteArrayInputStream(content.getBytes()));
                    object = visitNodes(document);
               }else{
                    object = null;
          } catch (ParserConfigurationException e) {
               e.printStackTrace();
               return null;
          } catch (SAXException e) {
               e.printStackTrace();
               return null;
          } catch (IOException e) {
               e.printStackTrace();
               return null;
          return object;
     private HashMap visitNodes (Node node){
          String nodeName = "";
          String nodeValue = "";
          ArrayList attributes = new ArrayList();
          HashMap object = new HashMap();
          Node childNode = node.getFirstChild();
          if (childNode.getNodeType() == Node.ELEMENT_NODE){
               nodeName = childNode.getNodeName();
               if (childNode.hasAttributes()){
                    attributes = visitAttributes(childNode.getAttributes());
               }else{
                    attributes = null;
               nodeValue = getNodeValue(childNode);
               object.put(nodeName, nodeValue);
               object.put("attributes", attributes);
          return object;
     private static String getNodeValue (Node node){
          if (node.hasChildNodes() && node.getFirstChild().getNodeType() == Node.TEXT_NODE && !node.getFirstChild().getNodeValue().contains("\n\t"))
               return node.getFirstChild().getNodeValue();
          else
               return "";
     private ArrayList visitAttributes(NamedNodeMap attributes){
          Node node;
          ArrayList ListAttributes = new ArrayList();
          String [] attribute = new String[2];
          for(int i = 0; i < attributes.getLength(); i++){
               atribute = new String[2];
               node = attributes.item(i);
               if (node.getNodeType() == Node.ATTRIBUTE_NODE){
                    attribute[0] = node.getNodeName();
                    attribute[1] = node.getNodeValue();
                    ListAttributes.add(attribute);
          return ListAttributes;
}This code functioning properly. However, as exist around 400 objects to the xml, I wanted to create a method for more easily invoking objects that are below other and that's what I can't get to do at the moment.
The code I use is:
import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
public class UtilClasses {
     public Object UtilClasses(String package, String object, String xml){
          try {
            Class class = Class.forName(package + "." + object);
            //parameter types for methods
            Class[] partypes = new Class[]{Object.class};
            //Create method object . methodname and parameter types
            Method meth = class.getMethod(object, partypes);
            //parameter types for constructor
            Class[] constrpartypes = new Class[]{String.class};
            //Create constructor object . parameter types
            Constructor constr = claseObjeto.getConstructor(constrpartypes);
            //create instance
            Object obj = constr.newInstance(new String[]{xml});
            //Arguments to be passed into method
            Object[] arglist = new Object[]{xml};
            //invoke method!!
            String output = (String) meth.invoke(dummyto, arglist);
            System.out.println(output);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SecurityException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        } catch (InstantiationException e) {
            e.printStackTrace();
          return null;
     }This is an example obtained from the Internet that I've wanted modified to my needs. The problem is that when the class calls this method to invoke the constructor and does not fail, this does not do what I expect, because it creates an empty constructor. If not, the parent class gives a casting error.
I hope that now have been more clear my intentions and that no one has fallen asleep reading this lengthy explanation.
greetings.

How to create new java objects in native methods?

Hello,
Is it possible to create java objects and return the same to the java code from a native method?
Also is it possible to pass java objects other than String objects (for example, Vector objects) as parameters to native methods and is it possible to return such objects back to the java code?
If so how can I access those objects (say for example, accessing Vector elements) inside the native code?
What should I do in order to achieve them?
Regards,
Satish

bschauwe is correct in that constructing Java objects and calling methods on Java objects from native code is tough and takes some study. While you're at it, you might want to check out Jace, http://jace.reyelts.com/jace. It's a free open-source toolkit that really takes the nastiness out of doing this sort of stuff. For example,/**
* A C++ function that takes a java.util.Vector and plays around with it.
public void useVector( java::util::Vector& vector ) {
// Print out all the contents of the vector
for ( Iterator it = vector.iterator(); it.hasNext(); ) {
cout << it.next();
// Add some new elements to the vector
vector.addElement( "Hello" );
vector.addElement( "world" );
} All this code just results in calls to standard JNI functions like FindClass, NewObject, GetMethodID, NewStringUTF, CallObjectMethod, etc...

HI !
i dont think that the servicepack is an issue in this case.
anyway i ahve tried it on 6.1SP4 and still getting similar results.
any pointers will be highly appreciated.
Thanks,

I just skimmed through your email. You said you
are using WLS 6.1 SP1. Can you try this using
the latest SP. There are many bug fixes done
after SP1.
Web service support in 6.1 is very limited. But, It
looks like 6.1 can handle the case you are trying out.

Problem with too small page size using Java 2D Printing API.

Hello,
I have problem with resolution of printer using Java 2D Printing API. Despite my printer has 600 x 600 DPI, inside java.awt.print.Printable.print(Graphics, PageFormat, int) I receive page format with 600 x 840 page size.
I have tried to set resolution using javax.print.attribute.PrintRequestAttributeSetand javax.print.attribute.standard.PrinterResolution, but with no result.
Can anybody solve this problem?
Regards,
Karl.

600 x 840 is a Point value; Point is defined as 1/72nd of an inch. Printers do have much higher DPI than this, but I believe that this DPI has to do with richness of the printed image, not an actual ability to color with that level of resolution. You might want to try calling zoom on your Graphics2D object. Otherwise, I don't know what else you can try.

Displaying Complex Java Objects using netui

I have a java object with the following structure.
obj1
int name;
String ID;
ArrayList obj2;//coniatns multiple obj2 objects
obj2
int name;
String ID;
ArrayList obj3; //coniatns multiple obj3 objects
obj3
int name;
String ID;
How and what netui tags can I use to display this kind of structure for obj1?
I tried repeaters and it is not working for me.
Also if I have a structure like this
ArrayList obj4; //contains arrays's of multiple items.
obj4
String[] eventTime;
String[] eventDate;
How can I display this in a grid fashion using netui? The netui:gid tag only
wirks with RowSet and I have an ArrayList?
If I want to use simple jsp and not use netui tags what is the context for accessing
my form that I have in my page flow from the jsp? e.g. if I have a form in my
page flow called listForm which has gets and sets for
String[] eventTime;
String[] eventDate;
what is the context I use in my jsp to print values of eventTime and eventDate
in a grid like fashion without using nteui? I tried 'request' context but it
does not work. In netui we can use actionForm or pageFlow etc but what about
simple jsp context?
Please reply soon. Thanks

Try the <netui-data:getData> tag in the workshop documentation, It gives an example

Java objects to Flex

Hopefully this is the right forum, if not pleas accept my
apologies.
We need to return dollars and percent type numbers from java
back to Flex using the BlazeDS interface.
When I create a Java test object to return that looks like:
public class Test2 implements Serializable{
private String abc = "abc";
private Date sqlDate;
private Time sqlTime;
private Timestamp timestamp;
private BigDecimal bd;
private float lFloat;
private Float bFloat;
private double lDouble;
private Double bDouble;
The constructor fills in values and the java server (JBoss)
returns the object back to Flex. The matching flex object looks
like:
[Bindable]
public class Test2
public var abc:String;
public var sqlDate:Date;
public var sqlTime:Date;
public var timestamp:Date;
public var bd:Number;
public var lFloat:Number;
public var bFloat:Number;
public var lDouble:Number;
public var bDouble:Number;
} /* Test2*/
when I print out the returned object using the trace command,
I get:
ReferenceError: Error #1056: Cannot create property BFloat on
jdbcTables.businessdelegate.Test2.
ReferenceError: Error #1056: Cannot create property LFloat on
jdbcTables.businessdelegate.Test2.
ReferenceError: Error #1056: Cannot create property LDouble
on jdbcTables.businessdelegate.Test2.
t2.bd=3.03
t2.lFloat=NaN
t2.bFloat=NaN
t2.lDouble=NaN
t2.bDouble=NaN
If I read
http://livedocs.adobe.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDo cs_Parts&file=00001103.html
correctly these fields should be converted properly.
Am I missing something or is the web page wrong? Is there
another kind of Java object can I use to return a floating point
number, I really don't like BigDecimal, it's sooo expensive.
Thanks
Bill Tims

Ok, I figured out THIS problem. The real issue is the
capitalization of the name. If I use an upper case character as the
2nd character, blaze and flex don't see that they are variable,
i.e. aBcd as a variable name doesn't work, whereas abcd does work.
Since this problem doesn't appear on the PHP side, I'm guessing the
problem is on the Blaze side.

Why user defined objects printing address

If we try to print Builtin java objects it will give The class name and properties. If we try to print a user defined class even though it extends from a bultin class it is not happening so why?

Hi Joyce,
The dll option allows you to add custom data validation and functions for the UDO. It doesn't have any affect on whether the default form opens or not.
What version of SBO are you working with? The default forms were enhanced in version 9 but, as far as I'm aware, if you selected the option in the UDO registration to use a default form then it should always open (ie if the menu option appears then the screen should be available). One thing to note is that you sometimes have to log out and log back in to SBO before the client recognises the new UDO (you should only need to do this the first time you add the UDO and not when making changes to an existing one).
Kind Regards,
Owen

Storing Java objects into a Derby db

Hi, Im new to Apache Derby, Id like to know how store a Java Object into a db field.
Im working with the JPCap library and the Packet class has many attributes and values, it will be easier if I could save the complete object in a just one field.
Thanks in advantage.

DB script:
"Create Table APP.PACKETS (ID INTEGER not null primary key, PACKET LONG VARCHAR FOR BIT DATA)"
Test:
import jpcap.packet.TCPPacket;
import java.io.ByteArrayOutputStream;
import java.io.ObjectOutputStream;
import java.io.ByteArrayInputStream;
import java.io.ObjectInputStream;
import java.io.IOException;
private static int increment;
public static void addPacket() {
System.out.println("Inserting...");
TCPPacket packet = new TCPPacket(12, 8080, 56, 78, false, false, false, false, true, true, true, true, 10, 10);
try {
ByteArrayOutputStream byteOutStream = new ByteArrayOutputStream();
ObjectOutputStream objOutStream = new ObjectOutputStream(byteOutStream);
objOutStream.writeObject(packet);
objOutStream.flush();
objOutStream.close();
byteOutStream.close();
PreparedStatement pstmt = conn.prepareStatement("Insert Into APP.PACKETS Values(?, ?)");
pstmt.setInt(1, ++increment) ;
pstmt.setBytes(2, byteOutStream.toByteArray());
pstmt.execute();
conn.commit() ;
System.out.println("Inserted!");
} catch(IOException e) {
e.printStackTrace();
} catch(SQLException e) {
e.printStackTrace();
public static void showPackets() {
String query = "Select * From APP.PACKETS ";
Statement st = null;
ResultSet rs = null;
int id = -1;
byte[] data = null;
try {
st = conn.createStatement();
rs = st.executeQuery(query);
while (rs.next()) {
id = rs.getInt("id") ;
data = rs.getBytes("packet") ;
ByteArrayInputStream byteInStream = new ByteArrayInputStream(data);
ObjectInputStream objInStream = new ObjectInputStream(byteInStream);
Object obj = objInStream.readObject();
objInStream.close();
byteInStream.close();
if (obj instanceof TCPPacket) {
TCPPacket p = (TCPPacket)obj;
System.out.println(p.dst_port); // Print anything
} else {
System.out.println("No Found!");
} catch(IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch(SQLException e) {
e.printStackTrace();
Thats one of several ways to insert Java Objects...

JAVA Object to XML to JAVA to XML

I have to achieve below in java:-
-Create input XMLs from Java class (that resides in a jar).
-Take input from user then store that data to Java object and submit for processing.
-After processing print response java object again in XML.
What is the best API to achieve this. Will be helpful if any example is available.

Thanks for the Reply =)
I have a Java Object that have some fileds like arraylist<Class> I want to take care of these fields as well.
If that arrayList<Class> have another fields that can be normal fileds or arraylist of another class, need to take care of all fields during XML generation
Example:-
Root Class have below fields
private int ArCt;
private ArrayList<ClassChild1> Ar;
Setters
Getters
ClassChild1.class
private int PlnCd;
private int cArCt;
private ArrayList cAr<ClassChild2> cAr;
ClassChild2.class
private String PlNm
XML Needed - Example from above object
<root>
<ArCt>1</ArCt>
<Ar>
<ClassChild1>
<PlnCd>S</PlnCd>
<cArCt>2</<cArCt>
<cAr>
<ClassChild2>
<PlNm>Plan1</PlNm>
</ClassChild2>
<ClassChild2>
<PlNm>Plan2</PlNm>
</ClassChild2>
</cAr>
</ClassChild1>
</Ar>
</root>

Generation of XML file from Java objects using castor

I have the following java file(Customer.java).
public class Customer
     private String ID;
     private FirstName firstName;
     private MiddleName middleName;
     private LastName lastName;
     private ArrayList address;
     public ArrayList getAddress() {
          return address;
     public void setAddress(ArrayList address) {
          this.address = address;
     public FirstName getFirstName() {
          return firstName;
     public void setFirstName(FirstName firstName) {
          this.firstName = firstName;
     public String getID() {
          return ID;
     public void setID(String id) {
          ID = id;
     public LastName getLastName() {
          return lastName;
     public void setLastName(LastName lastName) {
          this.lastName = lastName;
     public MiddleName getMiddleName() {
          return middleName;
     public void setMiddleName(MiddleName middleName) {
          this.middleName = middleName;
Using castor i have created an xml file(customer.xml) which has the following format.
<?xml version="1.0" encoding="UTF-8" ?>
- <customer ID="fbs0001">
<FIRSTNAME>Fred</FIRSTNAME>
<MIDDLENAME>B</MIDDLENAME>
<LASTNAME>Scerbo</LASTNAME>
- <ADDRESS>
<FIRSTLINE>No 18, Sheshadri road</FIRSTLINE>
<SECONDLINE>Gandhinagar Bangalore</SECONDLINE>
</ADDRESS>
- <ADDRESS>
<FIRSTLINE>ITPL</FIRSTLINE>
<SECONDLINE>Whitefield Bangalore</SECONDLINE>
</ADDRESS>
</customer>
I have used a mapping file to get this output.Is there a way where i can get the output xml in the following format without changing the Java object structure.If yes then please suggest how this can be done.
<?xml version="1.0" encoding="UTF-8" ?>
- <customer ID="fbs0001">
<FIRSTNAME>Fred</FIRSTNAME>
<MIDDLENAME>B</MIDDLENAME>
<LASTNAME>Scerbo</LASTNAME>
</customer>
<ADDRESS>
<FIRSTLINE>No 18, Sheshadri road</FIRSTLINE>
<SECONDLINE>Gandhinagar Bangalore</SECONDLINE>
</ADDRESS>
- <ADDRESS>
<FIRSTLINE>ITPL</FIRSTLINE>
<SECONDLINE>Whitefield Bangalore</SECONDLINE>
</ADDRESS>
I mean the output xml file should have the address as a separate tag not withing the root tag customer.

Hello,
Castor's own discussion groups might be able to point you to the solution you're looking for (if this use case is possible using Castor).
Oracle has its own object-to-XML mapping tool that is part of the TopLink product. It allows you to map existing objects to an existing XML Schema. This can be done visually using the TopLink Workbench, or programmatically using the TopLink APIs. TopLink OXM also supports the JAXB specification.
Using TopLink OXM to get the desired XML result I would recommend the following. Map the Customer and Address classes to XML, but don't map the relationship between Customer and Address. Then make the calls to the marshaller something like the following:
marshaller.marshal(aCustomer, System.out);
for(int x=0; x<aCustomer.getAddress().size(); x++) {
     marshal(aCustomer.getAddress().get(x), System.out);
Example - Using TopLink OXM to map an existing object model to an existing XML Schema:

Configure client printer in java.awt.print

I have number of records in database.
If User clicks on PRINT button (ON A JSP PAGE)each record should be printed(ON CLIENT PRINTER) on a separate sheet.
I can only able to access printer connected to server not to client.
I am using javax.print and java.awt.print packages

I am not sure this..
Instead of if pls give while and check:
try{
while(rsValue.next()) {
g.setFont(fntHeading);
g.setColor(Color.red);
g.drawString("Main Report",200,100);
