Xml-bean-xml
hi,
i'm looking for a tool/technology that can build an xml document/schema, representing a java bean, and visa versa can load a data from an xml document into a java bean object .
there is always an option to build something like this, but i guess there are well designed ready applications that can save my time and efforts.
thanks for your help.
Hi,
Try this tool: Liquid XML Studio 2008 freeware version. I used it to create a XML file and XML schema from the data of a bean. Just try it.
To Parse data from XML to a bean take a look at JAXP or JDOM parsers (depending on your requirements you will have to use one or another, but the latter is easier to use).
regards,

EJB 3.0 and creating bean .xml files for DataControl
In entity beans I haven't parameter updateble in source for column witch represent Id. I generate Id with TableGenerator strategy.
@TableGenerator(name="TEST_SEQ", initialValue=1, allocationSize=1)
@Column(nullable = false)
@GeneratedValue(strategy=GenerationType.TABLE,generator="TEST_SEQ")
@Id
private Long id;When I create DataControl why some <entity bean>.xml files have IsUpdateable="0" parameter for attribute witch represent Id (primary key) column in entity bean?
<Attribute Name="id" Type="java.lang.Long" IsUpdateable="0"/>In some files this parameter have default value (true), that is it does not show in source!
If I use datacontrol (method findAll for example) with selectOneChoiche component error is:
The selected target attribute has read-only access.Please select an updatable attributeWhen I modify files and after that refresh or create new DataControl I loss my changes in files.Hi Ric,
This is the test case which describe my problem.
Test entity:
@Entity()
@Table(name="TEST")
@NamedQueries({
@NamedQuery(name = "Test.findAll", query = "select o from Test o"),
@NamedQuery(name = "Test.findById ", query = "select o from Testo where o.id = :id")
public class Test extends BaseTest implements Serializable {
@Id
@TableGenerator(name="TEST_SEQ", initialValue=1, allocationSize=1)
@Column(name = "ID", nullable = false)
@GeneratedValue(strategy=GenerationType.TABLE,generator="TEST_SEQ")
private Long id;
private String test;
public String getTest() {
return test;
public String setTest(String param) {
this.test=param;
public Long getId() {
return id;
private void setId(Long id) {
this.id = id;
}Base entity:
@MappedSuperclass
public abstract class BaseTest implements Serializable {
@Column(name = "LASTCHANGE")
private Timestamp lastChange;
public MasterEntity() {
public void setLastChange(Timestamp param) {
this.lastChange = param;
public Timestamp getLastChange() {
return lastChange;
}Main entity:
@Entity()
@Table(name="MAIN")
@NamedQueries({
@NamedQuery(name = "Test.findAll", query = "select o from Test o"),
@NamedQuery(name = "Test.findById", query = "select o from Test o where o.id = :id")
public class Main extends BaseTest implements Serializable {
@Id
@TableGenerator(name="MAIN_SEQ", initialValue=1, allocationSize=1)
@Column(name = "ID", nullable = false)
@GeneratedValue(strategy=GenerationType.TABLE,generator="MAIN_SEQ")
private Long id;
@ManyToOne
@JoinColumn(name = "IDTEST", referencedColumnName="ID")

public Long getId() {
return id;
private void setId(Long id) {
this.id = id;
public Long getTest() {
return test;
private void setTest(Test test) {
this.test = test;
}The part code of session bean:
public Main findById(Long id){
return em.find(Main.class, id);
}When I create DataControl from this sessionBean, the Test.xml(ENTITY->Test) file is generated.
Test.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<JavaBean xmlns=" http://xmlns.oracle.com/adfm/beanmodel" version="11.1.1.45.24"

isJavaBased="true">
<Attribute Name="id" IsUpdateable="0" Type="java.lang.Long"/>
<ConstructorMethod IsCollection="false" Type="void"
id="Test"/>
</JavaBean>Questions:
Why attribute "id" have property isUpdatable="0" ?
I didn't specify "update=false" on my entity 'Test' for that column.
In witch case propery isUpdateble have value "0", "1", "2", "true", "false"? -
Stateless session Bean - xml and ejb-jar.xml file ???
Dear Experts,
Stateless-session bean
For Creating an ear file
we need ejb-jar.xml and weblogic-ejb-jar.xml files
Is these files are already available
or we have to type these files ??
Advance Thanks
Rengaraj.RMy best advice: surrender to use an IDE.
You wonder sometimes at how much productivity (read as 'time') could be wasted by doing something that could be done automatically. For a learning experience or a once only exercise is fine but as a routine thing, not worth it.

Creating XML file from Java Bean
Hi
Are there any standard methods in Java 1.5 to create XML file from java bean,
i can use JAXB or castor to do so,
But i would like to know if there is any thing in java core classes,
I have seen XMLEncoder, but this is not what i want.
Any ideas

Create XML dynamically from schema and Java bean
Hi,
I'm looking for suggestions on the best approach to create an XML file programatically from a schema and Java bean.
The schema used is not fixed and may vary with each request so a dynamic way to create the XML is required.
Is there an API available that allows me to achieve this easily? Any help would be appreciated to point me in the right direction.
Thanks.XMLBeans or JAXB should work for you.

How to get an XML string from a Java Bean without wrting to a file first ?
I know we can save a Java Bean to an XML file with XMLEncoder and then read it back with XMLDecoder.
But how can I get an XML string of a Java Bean without writing to a file first ?
For instance :
My_Class A_Class = new My_Class("a",1,2,"Z", ...);
String XML_String_Of_The_Class = an XML representation of A_Class ?
Of course I can save it to a file with XMLEncoder, and read it in using XMLDecoder, then delete the file, I wonder if it is possible to skip all that and get the XML string directly ?
FrankI think so too, but I am trying to send the object to a servlet as shown below, since I don't know how to send an object to a servlet, I can only turn it into a string and reconstruct it back to an object on the server side after receiving it :
import java.io.*;
import java.net.*;
import java.util.*;
class Servlet_Message // Send a message to an HTTP servlet. The protocol is a GET or POST request with a URLEncoded string holding the arguments sent as name=value pairs.
public static int GET=0;
public static int POST=1;
private URL servlet;
// the URL of the servlet to send messages to
public Servlet_Message(URL servlet) { this.servlet=servlet; }
public String sendMessage(Properties args) throws IOException { return sendMessage(args,POST); }
// Send the request. Return the input stream with the response if the request succeeds.
// @param args the arguments to send to the servlet
// @param method GET or POST
// @exception IOException if error sending request
// @return the response from the servlet to this message
public String sendMessage(Properties args,int method) throws IOException
String Input_Line;
StringBuffer Result_Buf=new StringBuffer();
// Set this up any way you want -- POST can be used for all calls, but request headers
// cannot be set in JDK 1.0.2 so the query string still must be used to pass arguments.
if (method==GET)
URL url=new URL(servlet.toExternalForm()+"?"+toEncodedString(args));
BufferedReader in=new BufferedReader(new InputStreamReader(url.openStream()));
while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
else
URLConnection conn=servlet.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
// Work around a Netscape bug
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
// POST the request data (html form encoded)
DataOutputStream out=new DataOutputStream(conn.getOutputStream());
if (args!=null && args.size()>0)
out.writeBytes(toEncodedString(args));
// System.out.println("ServletMessage args: "+args);
// System.out.println("ServletMessage toEncString args: "+toEncodedString(args));
BufferedReader in=new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
out.flush();
out.close(); // ESSENTIAL for this to work!
return Result_Buf.toString(); // Read the POST response data
// Encode the arguments in the property set as a URL-encoded string. Multiple name=value pairs are separated by ampersands.
// @return the URLEncoded string with name=value pairs
public String toEncodedString(Properties args)
StringBuffer sb=new StringBuffer();
if (args!=null)
String sep="";
Enumeration names=args.propertyNames();
while (names.hasMoreElements())
String name=(String)names.nextElement();
try { sb.append(sep+URLEncoder.encode(name,"UTF-8")+"="+URLEncoder.encode(args.getProperty(name),"UTF-8")); }
// try { sb.append(sep+URLEncoder.encode(name,"UTF-16")+"="+URLEncoder.encode(args.getProperty(name),"UTF-16")); }
catch (UnsupportedEncodingException e) { System.out.println(e); }
sep="&";
return sb.toString();
}As shown above the servlet need to encode a string.
Now my question becomes :
<1> Is it possible to send an object to a servlet, if so how ? And at the receiving end how to get it back to an object ?
<2> If it can't be done, how can I be sure to encode the string in the right format to send it over to the servlet ?

Parsing XML from a session bean
Hi,
I am trying to use a Sax parser for parsing xml received from a back end
legacy system. The code is executed from a Session bean.
Debugging learned me that the parse() method on the parser hangs the
container without any error or exception trace. The code works fine outside
a container.
All help will be highly appreciated.
KurtI found out that the InputStream implementation used parsing source inside
the container is different
then from the one outside (other type of VM of course!). The Weblogic
implementation blocks at the end of
the stream, while the normal SUN JDK 1.3 returns. This is not a bug, the bug
I found is in my proxy that allows
the connection to the backend. This proxy allows HTTP connections, and I
parse the XML received over HTTP.
Regards,
Kurt

That's seems odd. Perhaps there is something going on in your document
handler code that triggers a hang in the environment of the server.
When you see the hang, instruct the VM to give you a thread dump (type
control-<break> on Windows, <control>-\ (backslash) on UNIX in the
window in which the server is running; the results are dumped to
stderr). That will show what every thread in the server is doing. If you
email or post the thread dump, I will take a look at it and see if I can
see what is going on. Also, let us know which platform, VM, parser, and
WebLogic version you are using.

Help required in building up the Java Bean for an XML data
Hi ,
I want to build a Java bean which will actually represent an xml data . The class will be named as User and it will typically represent the data in the follwing xml:
<user>
<cwsId>barbete</cwsId>
<firstName>William</firstName>
<lastName>Barber</lastName>
<status>true</status>
<role>
<roleCode>1000000177</roleCode>
<roleName>Customer Administrator</roleName>
</role>
<language>en</language>
<country>US</country>
<preferences>
<equipmentGroup>2717</equipmentGroup>
<dateFormat>MON-dd-yyyy</dateFormat>
<timeFormat>HH:MI AM</timeFormat>
<timeZone>-12:00</timeZone>
<daylightSavings>Y</daylightSavings>
<location>NC</location>
<recordsPerPage>10</recordsPerPage>
<historyPeriod>3</historyPeriod>
<distanceUnit>MILE</distanceUnit>
<fuelUnit>G</fuelUnit>
<unitIdDisplay>E</unitIdDisplay>
<smuUpdate>W</smuUpdate>
<countries>
<country>
<countryCode>GB</countryCode>
<countryName>UNITED KINGDOM</countryName>
</country>
<country>
<countryCode>US</countryCode>
<countryName>UNITED STATES</countryName>
</country></countries>
</preferences>
</user>
Now for single child nodes like cwsId of the main user node i have kept properties like
private String cwsId;
But i am not sure as to how to represent the nodes which contain subnodes like "preferences"node. Any ideas?What is the standard practice?One thing you could do is create an object model first, which will contain all the data for your user.
then all you need in the bean is a Hashtable with the name of the user as a key, and the user-object (which is actually the complete object model) as a value.
with the XML stated by you, you would get an object model something like this:
Class User
String cwsid;
String firstName;
ArrayList<Role> roles = new ArrayList<Role>(); //I'm assuming a user can have more then one role.
ArrayList<Country> countries = new ArrayList<Country>();
class Role {
String code;
String name;
class Country {
String code;
String name;
}And so on for all the varioous elemets of your XML. -

The Managed Bean in the faces-config.xml File
I am still very new to JSF. I am confused about the managed bean.
For example, I have a button in my web page. A click on this button invokes an action; say, ListAction.java.
In this ListAction class, I instantiate a business delegate; say, ListPersonnel.java and call a method in this business delegate to return an ArrayList: personnel. Of course, this business delegate goes through facade, DAO, etc. to populate the ArrayList. This ArrayList is a collecation of a JavaBean called PersonnelBean that gets and sets a number of personnel information; such as ssn, name, etc.
Upon this ArrayList is successfully populated and received by the ListAction class, I am going to display a web page with a table. In JSF, it is <h:dataTable ...>.
My questions are regarding the managed bean in the faces-config.xml file.
1. Which one is my <managed-bean-class>? packageName.ListAction? or packageName.PersonnelBean? or something else?
2. What should be my <managed-bean-name>? I guess that I can give a name I like. Is it right? What about xyz?
3. Then, how do I specify the "value" attribute of my <h:dataTable ...> tag when I display a web page to show the data table? Is it correct to specify value="#{xyz.personnel}"? What is the correct specification if it is wrong?
4. I guess that I can give any name to the "var" attribute in the <h:dataTable ...> tag. Is it right?1. Which one is my <managed-bean-class>?
packageName.ListAction? or
packageName.PersonnelBean? or something else?ListAction
2. What should be my <managed-bean-name>? I guess
that I can give a name I like. Is it right? What
about xyz?Anything you like. xyz is OK.
3. Then, how do I specify the "value" attribute of my
<h:dataTable ...> tag when I display a web page to
show the data table? Is it correct to specify
value="#{xyz.personnel}"? What is the correct
specification if it is wrong?xyz.personnel is OK assuming that ListAction class has a public
method getPersonnel() which returns the ArrayList of PersonnellBeans.
4. I guess that I can give any name to the "var"
attribute in the <h:dataTable ...> tag. Is it right?Yes, you can give any name you like. -
XML Beans and Weblogic Server 8.1
Hi,
Does anyone know if XML beans is shipped with Weblogic 8.x (or is it only part
of the Weblogic Workshop) ?
Thanks,
ArunGreg,
The classes required for running these command line tools are all there, but
we have not put the script files in the version bundled with WebLogic
server. Its very likely to be part of the next service pack release.
Meanwhile, you can always run the classes from the command line, or write
your own script. For instance, the dumpxsb.cmd has the following:
set cp=
set cp=%cp%;%XMLBEANDIR%\xbean.jar
java -classpath %cp% com.bea.xbean.tool.XsbDumper %*
So you can always write this on your own, or just run the concerned class
from the command line.
Let me know if you have any further queries.
Regards,
Anurag

How to access backing bean of a xml component , in a managed bean of ADF
Hi,
We wrote a xml component in JSF and this component is used in ADF project by including the component as jar .
In a master detail page , we need to update the value of the xml component, when the master row is changed. How to do this.
We are trying to do this by accessing the backing bean of the xml component in ADF project's managed bean. So when ever the row changes, we can access the managed bean in ADF and then can set the value of the xml component by accessing it's backing bean
But i can't access the backing bean instance of the xml component in the ADF managed bean. Could you let me know how to do this. Thanks .Thanks for the response Shay. The xml component is added as a custom component , with a separate faces-config.xml file . This component is added to ADF project as a jar with a custom tag.
In the ADF project , i'm having different managed beans and i can access them from a different managed bean.
The issue is, i can't access the added custom component's backing bean which is available from a different jar , defined in a separate faces-config.xml file . This backing bean is defined with request scope. -
