How to populate form bean (Action form) from Action (Struts)

Hello to all..
I have a problem populating a from bean in struts from Action class...
What I would like is ..
1. how can I populate a formbean from Action so when a page (JSP) with tags will be displayed some tags will be set and some no (depends on data from database)..
example...
look at the picture...
http://freeweb.siol.net/peterv6i/ax1.jsp
I have a AO2.jsp page linked to action2 and also i have a formbean with set/get methods...
nex step.. when I call action2 I' retrive datas from my database and in Action class I would like to populate formbean which is from page AO3 (which will be displayed)..
Is this possible? here is my code but work only for 1 user.. if there are 2 or more users on page I get internal server error (Exception)..
this is my Action class
public class Action2 extends Action
public[b] ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
System.out.println("Action2");
session = request.getSession();
if (session.isNew()) {
response.sendRedirect("AO2.jsp");
AO3formbean frm = new AO3formbean(); <-- this is formbean from page AO3.jsp which I like to populate
frm.setName("xxxxxx");
frm.setSurname("ekekelek");
session.setAttribute("AO3formbean", frm); <-- here I put a formbean in session
return mapping.findForward("success");
then the AO3.jsp page will be called which use a AO3formbean... and here problems come... If only one user use the application all is ok.. but when two or more users use the same form with different session the page will not work well.. sometimes i get exception, sometimes white page.. sometimes nonsense datas are displayed..
Anybody know if is possibile to populate a formbean and store it in session or I must change whole code?
for example...
In my form i must enter a car assicurance policy number... (page AO2.jsp)..
then in the action form I must connect to my database and retrive information from table and populate bean which is also a formbean on the page AO3 which will be desplayed.. (if I'am doing something wrong please let me know the right way)
best regards

Passing values to form bean string array from dynamic added textboxes

Hi,
I am unable to pass values to form bean string array from a jsp in which I have incorporated dynamically adding of textboxes in javascript.
I have given add/delete row option in the jsp. If there is single row, this is working fine. But after adding a row, I am not able to either do any validations on added textboxes or pass the values to the String array form bean variable.
code snippet:
var cell6 = row.insertCell(4);
var element5 = document.createElement("input");
element5.type = "text";
element5.className = "formtext1";
element5.size = "5";
element5.value = "00.00";
element5.name= "qty"; // this is a string array of the form bean.
element5.onchange=function() {checkNumeric(this);};
cell6.appendChild(element5);
<html:text styleClass="formtext1" property="qty" value="" size="5" styleId="qty" onchange="checkNumeric(this)"/></td>
form bean declaration
private String[] qty; Please help.

Shivanand,
There's no need to post that much code when you could create a very short test case that demonstrates only the problem you are having.
You're using &NAME. notation on something that isn't a page or application item. You can't reference PL/SQL variables that way (or any other way) outside the PL/SQL scope. For your situation, you could create a page item named P55_DOCID and assign it a value in the PL/SQL process (:P55_DOCID := DOCID;), then reference &P55_DOCID. in HTML areas like the success message.

hi,
assuming u use jstl, u need to create javascript variable during html generation out of the values got from struts form bean. it could look like this:
------ .jsp file ----
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<script type="text/javascript">
var X = [];
var Y = [];
<c:forEach items="${formBeanName.mdfProductNames}" var="grpProdName">
X.push( '${grpProdName.mdfProductName}' );
Y.push( '${grpProdName.subGroup}' );
</c:forEach>
// here u already have the two arrays filled up with data
</script>
------- end of .jsp file
"formBeanName" is a name of a formbean u use to store the list of your beans

How to populate Java Beans List from the DB ?

Hi,
I have three tables called State,District and College.
Assume, State table has fields statid,statename,statedescr
District table has fields districtId,districtname,districtdescr and stateid
College table has fields collegeid,collegename,collegedescr and districtid
and all ids for the respective tables are primary keys .. and District and College tables have foriegn keys as expected...
I want to send the whole information to the front end... I had designed three beans StateBean,DistrictBean and CollegeBean.. where all the three beans will have the related fiields and respective getter and setter methods like below
StateBean -- stateid,stateName,stateDesc and DistrictBeanList
DistrictBean -- districtid,districtName,districtDesc and CollegeBeanList
CollegeBean -- collegeid,collegeName,collegeDesc
I would like to have the JDBC code (any driver,any DB) so that I need to build one StateBeanList (collection of all the statebeans information) ... (like how to write the query to get the whole information from the DB and populate the same into one list..(Query or queries + resultset operation)
I hope you understand my problem ...
Please let me know if I have to be more clear...
Thanks in Advance,
Vidhya...

Thanks Sachin,
Atleast you understand something of my requirement..
But Actually I want the logic like
if the query is like
select * from State
while(rs.next) {
StateBean object = new StateBean(); // StateBean
object.yourcorrespondingsetter(rs.getString(1));
object.yourcorrespondingsetter(rs.getString(2));
object.yourcorrespondingsetter(rs.getString(3));
object.setDistrictBeanList(districtbeanlistalreadypopulated); // how to populate the list of districtBeans list before ....
listobject.add(object ); // object internally has to have districtBean list, so the district bean list has to be loaded with all the distrct Beans in which every DistrictBean will be loaded with list of CollegeBeans ... Which district belongs to which state and which college belongs which district is all there in the table information ...
Now I want the query or queries to do that .... Can someone help me ?

While
the contacts list is usually filled out for contacts that are outside the company, there are times when you would use a contacts list to store internal and external resources. Wouldn’t it be nice if you didn’t have to re-type your internal contacts’
information that are already in the system? Now you can with a little InfoPath customization on the contacts list.
Here’s our plan:
Create the contacts list, and open in InfoPath
Create a data connection to the User Profile web service
Customize the form adding some text, a people picker and a button
Create InfoPath rules that will populate the contact fields from the user fields in the User Profile store
Let’s get going! Before we begin, make sure you have InfoPath 2010 installed locally on your computer. I also want to give credit Laura
Rogers and Darvish Shadravan’s book Using
Microsoft InfoPath 2010 with Microsoft SharePoint 2010 Step by Step. I know it looks like a lot of steps, but it’s easy once you get the hang of it.
So obviously we need a contacts list. If you don’t already have one, go to the SharePoint site where it will live, and create a contacts list.
From the list, click the List tab on the ribbon, then click Customize form:
So now we have our form open in InfoPath 2010. Let’s add our elements to the form.
Above all the fields, let’s add some text instructing users what to do with the the field we’re about to add (.e.g To enter an existing user’s information, choose the user below).
Insert a people picker control by clicking the Person/Group Picker control in the Controls section of the ribbon. This will add a column to the contacts list called group.
Below the people picker, insert a button control from the same section of the ribbon as above. With the button still highlighted, click the Control Tools|Properties tab on the ribbon.
Then in the Label box, change the text to something more appropriate to our task (e.g. Click here to load user data!).
You can drag the button control a little larger to account for the text.
We should end up with something like this:
Before we can populate the fields with user data, we need to create a connection to the User Profile Service.
Add a data connection to the User Profile Service
Click the Data tab on the ribbon, and click the option From Web Service, and From SOAP Web Service.
For the location, enter the URL of your SharePoint site in the following format – http://<site url>/_vti_bin/UserProfileService.asmx?WSDL. Click Next.
Note - for the URL, it can be any SharePoint site URL, not just to the site where your list is.
For the operation, choose GetUserProfileByName. Click Next.
Click Next on the next two screens.
On the final screen, uncheck the box for “Automatically retrieve data when form is opened”. This is because we are going to retrieve the data when the button is clicked, also for performance reasons.
Now we need to wire up the actions on our button to populate the fields with the information for the user in the people picker control.
Tell the form to read the user from the people picker control
Click the Home tab on the ribbon.
Click the button control we created, and under the Rules section of the ribbon, click Manage Rules. Notice the pane appear on the far right.
In the Rules pane, click New –> Action. Change the name to something like “Query and load user data”.
Leave the condition to default (none – rule runs when button is clicked).
Click the Add button next to “Run these actions:”, and choose “Set a field’s value”.
For Field, click the button on the right to load the select a field dialog. Click the Show advanced view on the bottom. At the top, click the drop down and choose the GetUserProfileByName
(Secondary) option. Expand myFields and queryFields to the last option and highlightAccountName. Click ok.
For Value, click the formula icon. On the formula screen, click the Insert Field or Group button. Again click the show advanced view link, but this time leave the data
connection as Main. Expand dataFields, then mySharePointListItem_RW. At the bottom you should see a folder called group (the people picker control we just added to the form). Expand this, then pc:Person,
and highlightAccountId. Click Ok twice to get back to the Rules pane.
If we didn’t do this and just queried the user profile service, it would load the data of the currently logged in user. So we need to tell the form what user to load the data for. We take the AccountID field from the people
picker control and inject into the AccountName query field of the User Profile Service data connection.
Load the user profile service information for the chosen user
Click the Add button next to “Run these actions:”, and choose Query for data.
In the popup, for Data connection, click the one we created earlier – GetUserProfileByName and clickOk.
We’re closing in on our goal. Let’s see our progress. We should see something like this:
Now that we have the user’s data read into the form, we can populate the fields in the contact form. The number of steps to complete will depend on how many fields you want to populate. We need to add an action step for
each field. I’ll show you one example and then you will just repeat the steps for the other fields. Let’s update the Job Title field.
Populate the contact form fields with existing user’s data
Click the Add button next to “Run these actions:”, and choose “Set a field’s value”.
For Field, click the button on the right to load the select a field dialog. Highlight the field Job Title.
For Value, click the formula icon. On the formula screen, click the Insert Field or Group button. Click the Show advanced view on the bottom. At the top, click the
drop down and choose theGetUserProfileByName (Secondary) option. Expand the fields all the way down until you see the Value field. Highlight it but don’t click ok, but click the Filter
Data button, then Add.
For the first dropdown that says Value, choose Select a field or group. The value field will be highlighted, but click the field Name field
under PropertyData. Click Ok.
In the blank field after “is equal to”, click in the box and choose Type text. Then type the text Title.
Click ok until you get back to the Manage Rules pane. The last previous screen will look like this.
We’re going to update common fields that are in the user’s profile, and likely from Active Directory. You can update fields like first and last name, company, mobile and work phone number, etc. For the other fields, the
steps are the same except the Field you choose to update from the form, and the very last step where you enter the text will change. Here’s what the rules look like when we’re done:
We’re all done, good work! You can preview the form and try it now. Click Ctrl+Shift+B to preview the form. Once you’re satisfied, you can publish the form back to the library. Click File –> Quick
Publish. Once it’s done, you will get confirmation:
Now open your form in SharePoint. From the contact list, click Add new item. Type in a name, and click the button and watch the magic happen!

Struts: how to populate info into a form?

Hi there,
quick question in struts: a user logs in the system and immediately sees his account information (composed of name, address...)
the user's info is retrieved from the db during the login phase.
Q: after the login, how can I populate the user's info in the form of the accountPage.jsp?
I tried to do this (login.java):
UserInfomationFrom uif = new UserInformationForm();
uif.setUser(user);but that of course dies because of the scope
thanks

How to populate a multi row form in Apex

Hi
I have a form in Application Express built using "Tabular Form" option while creating the page. The table being filled by the form is as follows
Cell_ID(varchar) reading_date(date) Value1(num) Value2(num) Location(varchar2)
Now I need to do the following
1. I want the page to display 200 rows for data entry on page load itself instead of user clicking Add Row button 200 times. ( For every location 200 entries need to be made for 200 diff Cell_IDs at the same date )
2. I want each row to take value for the Date column from the single date picker item displayed on top of page instead of entering the same date 200 times by user.
3. The cell_IDs are automatically populated with values loc1_001 loc1_002 .......... loc1_200 on selection of Location from another Item (select list) placed on top of the page.
Please Help anyone. Looking forward to a response.

How to populate DB column with filename from file browse item?

Hi,
Using APEX 3.1.2, I'm trying to easily allow maintenance of a filename stored in a DB column (VARCHAR2(1000)). Using the column as a file browse item seemed to be the way to go, but of course I don't want the resulting file to be uploaded and it appears as though an existing filename is not shown in a form when the row is retrieved.
After much searching, I found Checking filename length in File Browse item before uploading , but I'm not able to connect the dots. I was thinking that I could create a hidden file browse item and use a button to call Javascript function to activate it, then save the resulting filename to my DB column item and wipe out the hidden item before it was uploaded. But the hidden item doesn't appear, so I'm not able to reference it's form input name.
Hopefully this mess makes sense. Anyone?
Thanks!
Rich
Edited by: socpres on Sep 5, 2008 2:02 PM because message was truncated after attempting to preview it first.

Hi John,
From what I can tell, the path of a local file browsed from a file browse item cannot be retrieved because of security concerns. Although, it seems that while Firefox 3 only returns the filename sans directory, IE6 returns the full path:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" dir="ltr">
<head><title>Form Test</title>
</head><body>
<script type="text/javascript" language="JavaScript">
function GetDirectory()
strFile = document.FileForm.filename.value;
intPos = strFile.lastIndexOf("\\");
strDirectory = strFile.substring(0, intPos);
alert(strDirectory);
document.FileForm.Directory.value = strDirectory;
</script>
<form id="FileForm" name="FileForm">
<input type="file" id="filename" name="filename" value="" onChange="GetDirectory(this.value)">
<input type="hidden" id="Directory" name="Directory" value="">
</form>
</body>
</html>
This Win-specific code displays the path via IE6, but not in Firefox 3. Then again, I can't seem to preview posts here using FF3, either...

How to populate data selection in infopackage from spreadsheet

Hello,
I have to load data for thousands of missing CRM orders into BI via the BI-CRM extractor 0CRM_SALES_ORDER_I . We have list of those missing orders in a spreadsheet.
How do I populate these order numbers into the data selection tab of the data source?
I tried adding multiple orders at a time..butit doesnt load any data. On the other hand, when I was loading a single order at a time, it does load all the data.
Loading thousands of them manually will be a hectic job
Also, I cannot use ranges as they are not at all in range
Can somebody provide a workaround which hopefully will not involve any transports
Thanks!

This seems to be really cool! and I am able to open the editor in production too...
The only problem is I really have not ides how we can pass the parameters here..how we get the program to look up a spreadsheet and populate those records
Thanks for your input..it will be really helpful if you can provide me anymore information you have on htis..in the meanwhile, I will be doing some trial and error myself
thanks!

How-To populate SELECT LIST default value from SQL Query

OK, I've done my homework, and did not find my answer in the Forum, so here it is.
I have a Page that displays fields from a SQL Query. The Page also has below that radiogroups, checkboxes, and Select Lists to allow the user to change values in the fields that are displayed at the top of the Region. I am able to pre-populate the radiogroups and checkboxes by performing a SELECT in the 'Source value or expression' of the Source area of the Page Item.
However, I am unable to do the same for the Select List fields. Their default value ends up being the first value in the LOV ('-- None --' for NULL values). Source Used: Only when current value in session state is null. Source Type: SQL Query. Also, when I first go into the Page when running it, and check the Session State values, they are all null, so I don't understand why the field is not populated by the SQL Query statement as the radiogroups and checkboxes are.
Any suggestions??? I've tried all sorts of combinations.

Thank you for the suggestion.
I had considered that, but cannot do so, because we are using Oracle Application Express more for development than for data containment.
We have all our data in an Oracle 10.g DB which is separate from the OAEX server, and the OAEX app will reference that data via VIEWs and DB LINKs. We are doing so primarily as an added data security layer, where the data is housed separate from the app, in case the Web site is ever compromised. The data that can be viewed is restricted to a subset of the actual data that is available.
Since the data is on a separate server, (I assume) we will not be able to set the source type to Database column, because (I asume) that is dependent upon the data being housed by the OAEX server.
That still leaves me with having to populate the field with a SELECT statement from the Oracle DB. This unfortuneately is almost a show-stopper for me because of down-stream processing data requirements. Have not been able to come up with contingencies yet.

How to Populate a table type variable from a cursor

Hi
I have a stored procedure (P1) that returns a ref cursor as the output.
Another procedure (P2) receives this ref cursor (C).
In this procedure (P2), I want to do a Bulk Collect from this ref cursor (C) in
a table type variable that has been declared locally in the procedure P2. I have created appropriate Object Type and Table Types at the database level.
Please advise how to do it. I tried to do it in different ways, but was not able to do it - each time I faced incompatible data-type related issues.
