Return data from Java servlet in form of JSON encoded parameters in Javascr

How to return data from Java servlet in form of JSON encoded parameters in Javascript handler function call?
The same is implemented in php as the following
echo "sT.handleAjaxResponse(";
echo json_encode($response);
echo ");";
How to do the same in Java servlet?
Thanks.

With the rising popularity of JSON (especially with Ajax), support for it has started to appear in the Java community. I am not aware of any standardized approach yet, but expect it is likely we'll see that eventually. For now, you probably want to look at a third-party library such as the [JSON in Java Library|http://www.json.org/java/], Jettison, or [Java Tools for the JSON Format|http://jsontools.berlios.de/].

Can we Return values from Java Bean to Form

Hi All,
I have a Bean area defined on a Form. The Bean Area consists of a Text field which gets populated by path of a file selected using Browse button.
Can I return this path as a parameter from the Java Bean to the form? Is there any function for this?
Regards,
Prathima.

If you designed your bean to offer the ability to exact info/data from it, then yes you can get a value from the bean into the form (pl/sql) - using Get_Custom_Property
Refer to the following which is a good example of how to build a bean. Specifically look at page 12 where is shows how to use Get_Custom_Property.
This is NOT an Oracle supported or provided document or web site, but it is a very good example.

Returning data from child jdialog...problem

Hello
I have a parent form which calls a jdialog. I need to return data from the jdialog.
So i have this class which contains the varaibles i want to set.
public class ProtocolRecordType {
public int num;
public String name;
I from my main i call this class and method. Now i seem to be able to set object values to try and do a pass by reference in teh constructor, but if i use the same variable in a method it says unresolved symbol. Most of the code was generated with netbeans ide.
Can anybody explain this to me ?
Thanks
public class ProtocolsDialog extends javax.swing.JDialog {
/ Creates new form ProtocolsDialog */
public ProtocolsDialog(java.awt.Frame parent, boolean modal, ProtocolRecordType protocol ) {
super(parent, modal);
initComponents();
System.out.println("done constructor");
// public int y=0;
protocol.name="protoname"; <==========setting it here works, i can print this out when it returns to parent frame.
private void Protocol1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
//protocol.name="aaaa";
// ProtocolRecordType.name="";
System.out.println("proto1 selected");
protocol.name=("xxxtest"); +<=================this says cannot find symbol protocol.name+
}

How to pass submitted Data from a servlet to EJB Session Bean in JPA

How to pass Data User submitted Data from a servlet to EJB Session Bean when using JPA :
Hi ,
I have a jsp page in which the user fills up the Data and submits it to the servlet :
Inside servlets i am getting all the parameters and setting it to the Entity Class .
Sample Entity class is shown below :
@Entity
public class Employee {
@Id private int id;
private String name;
public Employee() {}
public Employee(int id) { this.id = id; }
public int getId() { return id; }
public void setId(int id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
}After calling setters of my Entity Class .
I am using JNDI lookup to call my session Bean method and pass this Entity class to the session Bean to persist data
Please let me know what will be the right approach :
1. Passing parameters whole as a Entity Class
that is
public void insertData(Employee emp)
}Or
2. public void insertData(String Name , int ID)
}

they are both right as they both work. Easy huh?
You might argue that if you have to set a lot of fields, use the entity as otherwise you get a method with a gigantic amount of parameters.

Is possible to capture the SP username of who is making submission of the data from an InfoPath 2010 form?

Hi all,
Does anyone know how to capture the SP username of who is making submission of the data from an InfoPath 2010 form? I looking to avoid the user need to type extra information like username/ manager name, etc; and then use code behind to be doing validation
before to push that data to an sql server.
Any suggestion , book reference , link is acceptable
thanks in advance
CRISTINA& MICROSOFT Forum

Hi Cristina,
Please check the following article with using web service UserProfileService.asmx to get the current user profile in InfoPath code behind and use the validating event to do some complex validation, it should help.

How to get return value from java and read by other application?

i want to read return value from java and the other application read it.
for example:
public class test_return {
    test_return(){
    public int check(){
        return 1;
    public static void main(String args[]){
       new test_return().check();
}from that class i make as jar file. How to read the return value (1) by other application?
thx..

If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

Return data from all columns apart from a certain data type.

Bit stuck on something, hope somebody here can help:
I want to do a 'select * from ' a table, to return all columns except ones of a certain datatype. ie. I want to return data from all columns, excluding columns of datatype 'SDO_GEOMETRY'.
This gives me the list of columns:
SELECT COLUMN_NAME
FROM   USER_TAB_COLUMNS
WHERE TABLE_NAME = 'ORDER_ITEM'
AND   DATA_TYPE <> 'SDO_GEOMETRY'; But I can't seem to take it any further...
Now if I knew the columns beforehand, then of course I could just list them, excluding the geometry column, but this is to be used for a plug-in for MS Word, where a user can pick database columns to dynamically fill a report from - but I don't want the geometry columns as these can't be handled in this way.

Hi Reggie,
> connects to the database and presents a list of tables
My guess is that this macro is written so it selects from all_tab_cols.
Change that plugin and let it select from a view like the one above. That way, the users won't be able to see/pick anything that you are not able/willing to present for them.
Edit:
You could even tease your users, and let them see the columns, but not being able to pick them.
create or replace view available_tab_columns
as
   select decode(pickable.data_type, null, 0, 1) pickable
         ,atc.* -- narrow down yourself
     from all_tab_cols atc -- or maybe user_tab_cols
         ,(select 'CHAR' data_type from dual union all
           select 'DATE' from dual union all
        select 'NUMBER' from dual
           -- complete positive list, yourself
          ) pickable
    where atc.data_type = pickable.data_type(+);Regards

The ways to return data from a stored procedure.

Hi, I know there are three ways to pass out a value from a Microsoft SQL stored procedure, but I have no clear idea what Oracle SP can do, I know Oracle doesn't support multi-recordset(v8), can not return a recordset by a inner select query, but I do know there is a cursor object, which doesn't like its counterpart in Microsoft SQL server, is a choice under most situation. Here I wonder anyone who is good at Oracle can give a list of all ways to return data from a SP, including example is more better, thanks.

Here is a way to get return a record from a function and a procedure. You need to be familiar with Oracle packages as well as stored procedures and functions:
CREATE OR REPLACE PACKAGE EmpPkg AS
cursor cEmp(pEmpno in number) is
select empno, ename, job, hiredate, sal
from emp
where empno = pEmpno;
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype);
END;
CREATE OR REPLACE PACKAGE BODY EmpPkg AS
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype IS
rEmp cEmp%rowtype;
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into rEmp;
close cEmp;
return rEmp;
END;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype) IS
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into prEmp;
close cEmp;
END;
END;
Here's how you use the package:
DECLARE
rEmp EmpPkg.cEmp%rowtype;
BEGIN
rEmp := EmpPkg.GetEmployee(7782);
dbms_output.put_line(rEmp.ename);
EmpPkg.GetEmployee(7902, rEmp);
dbms_output.put_line(rEmp.ename);
END;
Note that you can return any Oracle data type from a function. Likewise, you can specify any Oracle data type as an out parameter in a procedure. Also, you can make a parameter both an in and an out datatype like this:
PROCEDURE GetEmployee(pnEmpNo in out number);
I hope this puts you in the right direction.

Saving the data from two info path forms in to a single list in share point 2010

Hi ,
I have two info path forms are in share point page FM 1 and FM 2.
In FM 1 I am getting data from lists by using drop down and casket drop down and FM 2 i need to enter manually after entering
i want to save both forms information(FM 1 & FM 2 ) in to a single list of share point 2010
If any knows the solution please reply me
Thanking You,
Arun Darly

Hi，
Based on your description, my understanding is that you want to save the data from two info path forms in to a single list in share point 2010.
We can't save the data from two info path forms in to a single list, but we can
save the data from two info path forms in to a single library.
Open the FM 1 and FM 2 in Infopath(you have save it Locally once).
Publish the FM 1 and FM 2 as content types named FM 1 and FM 2.
Add the content types FM 1 and FM 2 into a document library, Then you can save the data
from two info path forms in to a single library.

Someone knows the reason of this error and can suggest what to make.

Antonio, maybe you can post this back to the Jacob list. As an alternative to Jacob, what about Apache POI or writing the data as comma-delimited and opening the file using Runtime?
Hope that may help.
Good luck.

Return data from spark list itemrenderer

Does anybody no how to return data from the itemrender for a spark list. say i had a checkbx in my itemrenderer how can I get that info back to my main component if its selected or not. I looked at datagrid and itemeditor but I really rather use a spark list. Thanks

thanks I also found another way to doing it. A click handler on my list when that fires I can check if checkbx has been selected by doing event.target.document.mycheckBx.selected this will not work if using currentTarget cause it take the info from the itemRenderer. Now I understand the difference between currentTarget and target.
not sure if this is a better way to access the data I think I might still just dispatch a event and do it your way.
Its weird that mx:list has a editItemRenderer and s:list does not
thanks again TK

It appears you are trying to store java objects (types) in a database rather than raw data (string, int, date types) that the object contains. If so, I don't think that ever really caught on. Most programmers store the raw data, then pull it out and populate a class. The problem with storing the object is that new versions of classes come out and your old version is stored in the database. If you just store the data, you don't have to worry about what version is in the database. You can populate the new version of the class with the same data.
Also, others can use sql to query your data and use it for their own use independent of what you intended it for. I think most people use the (browser) based utility that comes with the database to create the tables, normalize them, set up primary keys, set up foreign keys, etc rather then run an sql statement as you did above.
