Java Bean object

hi..
Can we create a java bean object in workbench and set properties in it through process? If yes, please provide, pointers to it.
Thanks and Regards
Ambika Mittal

To get one of your own objects into a LiveCycle process (so you can create a process variable of your type) you will need to create a custom component. Custom components allow you to create both services and java objects that can be accessed by LiveCycle.
In this case you would wrap your java object in a jar file that includes a component.xml file (this tells LC how to use your code). If you include a <data-type> entry for your objects then you will be able to create variables of your objects type.
I wrote a couple of articles on creating custom components that may help: http://www.adobe.com/devnet/livecycle/articles/dsc_development_pt2.html

Java Bean object in Developer 6

Hi
When i create a java bean object in developer 6.0 the object is

Dear,
Your path & class_path has not been set in the control panel.
Go to system, then environment set your required path. It will
work.

How to convert csv files into java bean objects?

Hi,
I have a CSV file, I want to store the data availabale in that csv file into java bean, I am new to this csv files how can I convert CSV files into java beans.
Please help me.
Adavanced Thanks,
Mahendra

You can use the java.io API to read (and write) files. Use BufferedReader to read the CSV file line by line. Use String#split() to split each line into an array of parts which were separated by comma (or semicolon). If necessary run some escaping of quotes. Finally collect all parts in a two-dimensional List of Strings or a List of Javabeans.

How to include PJC and Java Beans in forms

I have tried a lot to include java codes in my forms ..So I decide to start with ProgressBarPJC(cause it is tested and provided with demo) but I could not set implementation class of java bean object to
oracle.forms.demos.ProgressBarPJC it does not accept it but it accept ProgressBar instead of ProgressBarPJC. I don't know why? I have made changes in Forms90_builder_classpath to access f90all.jar and progressbar.jar. I have Progressbar.class and progressbarpjc.classs both but i don't know how to set implementation class to ProgressBarPJC.
don't you think there is lots of configuration and path setting to use any JPC or Jar in forms? I am totally confused with this integration.
Please solve this matter
Thanking you,
Neeraj

and even more information samples and step by step instructions are on the Java spotligh on the Forms Upgrade Center : http://otn.oracle.com/formsupgrade

Java Bean usage

folks
i have a pageflow and i have one jsp in a pageflow and i am using a Java Bean class inside this pageflow to collect all the information from the JSP when the user submits the page, Well i want to know whether i can use this Java Bean outside of the JPF as a value object or i should use a different value object, Infact my JPF is talks to a Java Control, So i was thinking how do i get that Java Bean object inside a Java Control,
Any advices is appreciated,
Thanks
portalman

here is an idea: forget about patterns, stop worrying about doing it "the one and only correct way" and simply use your brain.
Its all personal preference and usually very much depending on the situation. You could use only one bean, but some situations will call for the creation of a separate bean that can hold additional information, or even several beans. Sometimes the framework you use already forces the creation of specific beans.
There is only one thing that will help you to determine which situation calls for which approach: experience. Until then you'll just have to make plenty of mistakes like the rest of us have at the beginning of our careers. But there is one tip I can give you that may save you some time: if you look at your code and things just aren't as simple as they should be: you have a design flaw. Usually when you keep going with it, you'll hit some sort of limitation that'll cause you to see how the code design should have been from the beginning. Eventually you'll get into that situation often enough that you'll automatically do it right from the beginning. As I said: experience.

Returning java bean from web service

hello i just want to know if it is still platform independent if i make an array of java bean object as a return value from a webservice?
if the return value of a webservice is a java bean, is it required for the client to have a copy of the java bean class? what will happen if the client of the java webservice is in PHP or other language besides java? will it still be compatible?
thanks in advance guys..

Yes, you should be able to return a Java bean from a Web service. What will happen is your web service framework, such as JAX-WS (http://jax-ws.dev.java.net) will generate WSDL and Schema that describes the operation and its use of Java bean. Then the client web service framework used will take the WSDL and Schema description and generate something that can marshal/unmarshal the contents of the bean.

Urgent : java bean having bidirectional one to many relationship

Hi,
We have complex requirement in our application.
We need to copy java bean having bidirectional one to many relationship to another javabean having bidirectional one to many relationship..
E.g
Class Basket1 {
public String color;
pubic String type;
public List<Basket1> basketList = new ArrayList()
Class Basket2 {
public String color;
pubic String type;
public List<Basket2> basketList = new ArrayList()
We need to exact copy Basket1 to Basket2. We are in trouble to copy List of child because we do not have how many child Basket1 have of same type..
Can someone help us how we can implement such kind of complex object bidirectional one to many relationship??

I can't see anything bidirectional about these relationships. What I can see is a couple of BasketN classes that look identical so I don't know why they both exist, and they both contain lists of themselves as members, which suggests some kind of tree structure. Nothing bidirectional there. I can see tat these things can form circular object graphs but I don't see why you would want to do that.
We need to exact copy Basket1 to Basket2And I don't know what that means. Please explain.

How to rebind a bean object programmatically in EJB 3.0

hi,
There is a bean object (EJB 3.0) which i want to rebind. How can I do it through another application running under same netweaver server.
For eg,
      one session bean object is bound to "java:comp/env/Converter" jndi name by one application. Here, i need to modify this object and rebind to the same jndi name. so i used as follows,
   context.rebind("java:comp/env/converter", beanobj );
   //'beanobj' is the modified bean (modified attribute's value)
it was bound successfully, but when i look up the bean object, i got the ClassCastException,
like "java.lang.ClassCastException : $Proxy5_1001 at ......"
can anybody help me?
regards,
Panneer.

@Vladimir Pavlov
I did not understand what you are trying to convey...
Whenever an attribute of this bean is modified we want to access that latest value.... Is there any way to know, when the attribute is modified? Just with get/set we can not know, when it is modified... am i right?
We want to achieve this without modifying the existing source code of the EJB....
@ Ivo Simeonov
As of my knowledge, to use interceptors we need to modify the EJB source code, but we do not want to touch the source code....
All this has to be achieved dynamically when the application is deployed in the production.... is it possible???

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 ?

I 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 ?

Upload to Excel using Java Bean

Hi
My requirement is that to upload the data to an excel sheet from a JTable(JTable is actually a java bean which gets its input from forms) and the user need to be given either to view the excel/save the excel/print the excel in any of the networked printers.
Please cud someone help me with their inputs.
Thanks again
Deepa

can you send me your code bean and form?
I have example that i can send you to export to excel using webutil and OLE object.

Context mapping vs. Java beans

Hi,
I'm making a "Server" Component (Java Web Dynpro) that exposes a view to other "Client" Components (other Java Web DynPros). The Clients can insert the exposed view into their views to use the Server's services.
The Server, obviously, has to be initialized with specific data from the Client.
At first I thought of creating a context node in the Server, structured with all the attributes needed for its configuration, and then expose that node in the interface. In this way the Client creates a local copy of that node via node mapping and then populates its attributes with values. Once the client populates it in its wdDoInit() method, the embedded view's wdDoInit() method is called and the Server's View can initialize itself.
Now, instead, I was considering using Java Beans (a class that wraps all the data that I've currently put in the context) because:
1- The Client should not be able to alter the Server's configuration once it has been initialized. With context mapping the Client can alter at runtime the configuration node's content.
2- The Server configuration has to be shared between multiple Server's views. When passing a configuration NodeElement as argument to methods shared between views, I've always the problem that I have to deal with the type of the NodeElement (the public interface of the component controller, the private interfaces of the views).
What is the right way to do things in this scenario?
Thanks to anyone who drops an answer,
See you,
Pietro
PS. If it's unclear, let me know!

You can implement some inteface at server,
declare usage of this interface at client.
then,
you can initalise server component by getting that interface from server component,
and calling methods with desired objects as arguments.
other methods of this interface can be used to return server's configuration,
so it will be shared.

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.
