9i;JSP; BC4J Data Tags...

Hi,
What's different between these two tags in BC4J Data Tags pallet:
<jbo:InputText> & <jbo:InputRender>

Hello,
Here is the difference (from the online documentation)
<jbo: InputText> Inserts a text-input field form element into
your page.
JSP Syntax <jbo:InputText
datasource="datasourceId" dataitem="attributename"
[ cols=numberCharactersWide ]/>
Examples
Order Id:<jbo:InputText datasource="Orders" dataitem="Id" />
Description The input render converts all values to a String for
storage in the database.
<jbo: InputRender>
Inserts a input form element that allows user to edit data of
all types, including complex object types.
JSP Syntax
<jbo:InputRender
datasource="datasourceId"
dataitem="attributename"/>
Examples
<form enctype="multipart/form-data"
NAME="iForm" METHOD="POST"
ACTION="Submit_AddImage.jsp" >
Image Id:<jbo:InputRender datasource="ds1" dataitem="Id" />
Image File:<jbo:InputRender datasource="ds1"
dataitem="Image" /><input type="submit" /> </form>
Description
Input form uses a field render specific to the object type.
Hope this helps. You can search on the online documentation for
description about this and other components.
Thanks,

Jdev3.2,Jsp,BC4J, Data Tags : Unexpected exception Caught

I wrote an jsp aplication, with data tags based on BC4J module.
when I run the application the first time, everything is Ok. the second Time an Unexpected exception is thrown.
the first module displayed in the error message is
msg=null oracle.jbo.ApplicationModule oracle.jbo.html.jsp.JSPApplicationRegistry.getAppModuleInstance(java.lang.String, javax.servlet.jsp.PageContext)
I thought that the problem is the module so
I runned the application module in the BC4J tester tool every thing is ok
I created a new aplication module but without any result.
I created a jsp Application based on the same application module but using the datawebbean and everything is ok also.
and here is a code that let the exception thrown.
<%@ taglib uri="/webapp/DataTags.tld" prefix="jbo" %>
<jbo:ApplicationModule configname="test1.Test1Module.Test1ModuleLocal" id="Test1Module" username="wns" password="offline" />
<jbo:DataSource id="cat" appid="Test1Module" viewobject="TfixcategoryView" ></jbo:DataSource>
<select NAME="categoryList" size="10" multiple="yes">
<jbo:RowsetIterate datasource="cat" >
<option VALUE="<jbo:ShowValue datasource="cat" dataitem="Idcategory" ></jbo:ShowValue>"><jbo:ShowValue datasource="cat" dataitem="Dsnmcategory" ></jbo:ShowValue> </option>
</jbo:RowsetIterate>
</select>
can some help me to find a solution.
cheers

hi Juan
I didn't copy all the code source. but the releasepageresources tag is there. and I have only put this code because when I delete it no exception is thrown so the problem is there( in data tags).
more than this when this exception is thrown I have only to relog to a new windows 2000 session and no exception is thrown.

HOW TO: Create a JSP Edit Record Form Using BC4J Data Tags

This is a JDeveloper Tech Note found on the OTN Documentation page. This note describes the use of the BC4J data tags to create row edit/submit JSP pages. Here is the link:
http://technet.oracle.com/docs/products/jdev/technotes/datatag_input/Edit_Form.html

Are you using Java 1.4.* ?
Use JFormattedTextField.
import javax.swing.*;
import java.text.*;
import java.awt.*;
import java.util.*;
public class DateExample
    public static void main( String [] args )
      // Here's what you're interested in...
      DateFormat dateFormat = new SimpleDateFormat( "MM/dd/yyyy" );
      JFormattedTextField field = new JFormattedTextField( dateFormat );
      field.setColumns( 11 );
      field.setText( dateFormat.format(new Date()) );
      JPanel panel = new JPanel();
      panel.add( field );
      panel.add( new JButton( "Hey" ) );
      JFrame f = new JFrame();
      f.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
      f.getContentPane().add( panel );
      f.pack();
      f.setVisible( true );
}It also works with other types of Format objects (ex. Currency, Decimal, etc.)

HOW TO: Create a JSP Insert Record Form Using BC4J Data Tags

This is a JDeveloper Tech Note found on the OTN Documentation page. This note describes the use of the BC4J data tags to create insert/submit JSP pages. Here is a link:

You can loop throgh query records whit an implicit cursor (which automatically manages the open cursor, fetch and next record):
for rec in (select intime,outtime,barcode,attend_date from dail_att; )
loop
     t_in :=rec.intime;
     t_out :=rec.outtime;
     t_code :=rec.barcode;
     t_date := attend_date;
         PUT YOUR CODE HERE ... (if ..then... elsif... logic)
         you can avoid setting variables 'cause you can directly use the implicit cursor variables: rec.intime etc.
end loop;
END;Anyway, I suggest you to check the where condition of your block ... because if not all data are retrieved there should be a problem in your query ... so even the cursor (if based on very same query) will return less data than expected.

Creating rows Using BC4J Data Tags

Hi!
I want to create rows using BC4J data tags.
I have 2 jsp pages: one containig forms and one to insert data.
Is it possible to insert new rows into 2 or more tables?
How can I differ the attributes to one table and to another?
How can I do this?
Thanks!

The path is:
Select "File/New" in the menu.
Select "BC4J JSP" in the gallery.
Select "Browse & Edit Form" wizard.
This is in JDeveloper 9.0.2.

Question about BC4J data tags, Oracle sessions and Locking!

Hi ,
I have seen numerous examples of JSPs using data tags and in all the examples the data tag for the application module has the "username" and "password" harcoded in it.
My questions are:
1) For a stateful application should we be including the username and password in every JSP page. I personally believe that we should not.
2) If we have a username and password in every JSP page will it not start a new ORACLE user session and if so will it not cause locking problems?
3) If we don't hard code the username and password in every JSP page, will it reuse the same ORACLE session ?
4) How do we avoid locking problems when we use data tags?
5)I can understand the inclusion of username and password in every JSP page if it is a stateless application but again Is there a way we can avoid hardcoding the username and password in every single page?
I would appreciate if some one can let me know if any of my assumptions are incorrect.
JDeveloper Team/Juan any advice?

The username and password are optional. They can be provided via the connections.properties file. The multple entries for username and password don't mean that separate connection are made. The first time the ApplicationModule tag is encountered, your application instance is created. If you are running in reserved mode (look at your releasePageResources tag) the application instance is kept until your Http session times out. If you are running in Stateful or Stateless mode, you application instance is returned to the application pool and retrieved the next time you need an instance. Please refer to the application pool documentation and to the source in oracle\jbo\common\ampool provided in jbohtmlsrc.zip.

Jsp,bc4j,Data web Bean , error : NO ROWS AVAILABLE FOR EDITING

HI
I'm developping a jsp application based on Bc4j. when trying to insert a new row with missing fields which must be not null,
in order to be able to edit the row and correct the non seized fields, I display the edit page and it works for several views. but this time when editing fields and submitting the edit form an error is raised with the message no rows available for editing.
the particularity for these views(which causes the error) is that are details for a view which is detail for an other.
can someone please suggest some solution for such a problem
thanks in advance

this is a typicall error that occurs when trying to execute the Row data tag with action "Update" and there is not row obtained through the rowkeyparam (normally MyRowKey url parameter passed from the Edit page). I don4t have sufficient information to give you an exact solution.
I don4t understand all your escenario, you spoke about "Insert new row with missing values in required fields", but if you don4t specify a right value to that fields, the insert fail.
Then you display the Edit page to edit that just inserted row, to correct (specify?) the values of that fields. The error occurs in the EditSubmit page.
The EditSubmit page execute de Row data tag, according to the implementation of Rowtag, first recover the row reference (from rowkeyparam url parameter) and then, if that row reference is null, throws the "No rows available for editing" Runtime Exception. This means that the datasource used in your EditSubmit page not include that RowKey reference (obtained from Edit page as Url parameter).

JSP, BC4j: Date Conversion

Hi,
In my JSP application, I have a form that is used to inert data. I have used the input data tag to allow users to enter date for a particular field. The date appears in the format "2000-01-31". How do I convert it to the format "31-JAN-01"? I used the following code but it gives me the result as "31-Jan-01" instead of "31-JAN-01":
<%
SimpleDateFormat myFormat = new SimpleDateFormat();
SimpleDateFormat myFormat2 = new SimpleDateFormat();
myFormat.applyPattern("yyyy-MM-dd");
myFormat2.applyPattern("dd-MMM-yy");
String tempDisplayDate = new String (myFormat2.format(myFormat.parse("2000-01-31")));
%>
Thanks

".toUpperCase()" on that tempDisplayDate, either during or after creation?

JSP, BC4J, Row Tag: what is the best way to delete multiple rows?

Hi all.
I have a JSP Edit page with three datasources on it. The tables these VO's represent (A, B and C) have a Parent --> Child (1:1 between A and B) relationship and then another Parent --> Child (1:n between B and C) relationship. So the user retrieves one row for Table A, 1 matching row for table B and then between 0 and 6 matching rows for Table C (there cannot be more than 6 because the user can only add these rows from a finite list).
In my EditSubmit page, I want to perform a RowTag Update action on Tables A and B and they both work no problem. They can't update any rows from Table C but they can add or delete from the list of 0 - 6 rows (the UI is actually a list of 6 checkboxes that they can turn on or off). I figure that the easiest way to handle this rather than keep a list of original values and compare them is simply to delete all existing rows and then add any that the user checked.
This is causing a problem. I have added a hidden field to the form that picks up the RowKey for each existing row. I can get these RowKeys in the Submit page but cannot find a way of using them with the Delete Row Tag.
In the end, the only way I could get it to work was the following code (which I stole from the RowTag.java file in jbohtmlsrc.zip):
if (stakeMailRowKeys != null) {
for (int counter = 0; counter < stakeMailRowKeys.length; counter++) {
Key stakeMailKey = new Key(stakeMailRowKeys[counter], stakeMailingRS.getViewObject().getKeyAttributeDefs());
stakeMailRows = stakeMailingRS.findByKey(stakeMailKey,1);
stakeMailingRow = stakeMailRows[0];
// Tell the row to delete itself from the database
stakeMailingRow.remove();Is there a simpler way to do this (I figure there probably is)? I have another problem with updating the constrained View Objects but I will leave that out of this thread for now.
TIA,
Simon

I don't know if this will help you, but this is what I do:
I separate the logic into a delete.jsp page. If you can create a View Object that will represent the rows you want to delete and append a where clause to select only the rows you want to delete. Then loop through the view deleting each row. Lets just say you have department and employee tables. and you want to delete employees within a given department. Create a view object that brings back all employees.
In your delete.jsp find out the department no. by request.getParameter("dept_id");
then append this to the where clause of your view Object and execute the query:
vo.setWhereClause(request.getParameter("dept_id");
vo.executeQuery;
now loop through and remove the rows:
while(vo.next){
vo.getCurrentRow().remove();
and commit or post changes accordingly.
There are many ways of doing this action. The easiest way I have found is to create the ViewObjects based on what actions you want to take on them. Make bc4j work for you.

JSP/BC4J app: How to get view object row data into a scriplet variable?

I have a JSP application using BC4J data tags. Within a rowsetiterate tag, how can I get the data value of an attribute for the current row into a scriplet variable?
Thanks,
Steve

Using the <jbo:Row> tag like this:
<jbo:RowsetIterate .... >
    <%--
     | Establish a scriptable variable "curRow" for the current row
     +-->
    <jbo:Row id="curRow" action="current"/>
    <%
      String foo = (String)curRow.getAttribute("YourAttrName");
    %>

Nesting a BC4J JSP data tag within a Struts tag?

Has anybody tried nesting a BC4J JSP data tag within a Struts JSP tag? I can't get it to work. For example,
<logic:equal name="sort" value="<jbo:ShowDefinition datasource='ds' dataitem='CustomerName' definition='ColumnName' />">
blah blah blah
</logic:equal>

Try using single quotes in the value=' ' and double quotes in the jbo tag usage.

JSP, Data tags, How to build a form edit with multiple records

Hi, I'm using Jdev 9i.
I would like to have a JSP form where I can update, delete, insert records displayed in the same page.
I know that I can use the data tag jbo:DataEdit to do it, but it only works with a single record, I want to have several records in the same page, displayed horizontally.
The best example is a form to add items in an invoice:
Productid description quantity price
1001 xxx 10 20.00
1002 yyy 15 30.00
1003 zzz 7 10.00
Could you give some help please?
Thanks in advance.

The form display is dictated by how you process the submit. I would build the form by using standard html tags. Here is another pseudo example:
<FORM ACTION="target.jsp" >
<TABLE>
<TR>
<TD>
DeptNo
</TD>
<TD>
DName
</TD>
<TR>
<%
int nRow = 0;
%>
<jbo:RowsetIterate datasource="ds">
<%
// increment the row number
nRow++;
String sDeptno = "Deptno" + nRow;
String sDname = "Dname" + nRow;
String sRowKey = "RowKey" + nRow;
%>
<jbo:Row id="myrow" action="current">
<TR>
<TD>
<input type="text" name="<%=sDeptno%>" value='<jbo:ShowValue dataitem="Deptno" />' />
</TD>
<TD>
<input type="text" name="<%=sDname%>" value='<jbo:ShowValue dataitem="Dname" />' />
<input type="text" name="<%=sRowKey%>" value='<jbo:ShowValue dataitem="RowKey" />' />
</TD>
<TR>
</jbo:Row>
</jbo:RowsetIterate>
<input type="submit" />
</TABLE>
</FORM>
NOTE: This should get you started!!!

Adf-Struts/JSP/BC4J- and setting date fields from jsp

Hi,
I'm working with the new ADF Frameworks (JDev 9.0.5.1) and ran into some questions regarding exception handling using BC4J, Struts and JSPs.
I have a DATE column in database and an entity and VO with a datefield with type oracle.jbo.domain.Date.
My JSP shows a textfield and the user should enter a valid date. Everything fine, until date is of wrong format or contains illegal characters...
Problem:
ADF tries to do a setAttribute on the datefield in VO row which expects a parameter with type oracle.jbo.domain.Date. When the user entered e.g. "NiceWeather" as date, I get an IIlegalArgumentException while converting to the correct Date format. This exception isn't thrown by bc4j as AttrValException and therefore my JSP renders a global error instead of a message directly behind the date field.
I tried to validate the datefield in my DataForm and in my Action in the validateModelUpdates() method, but with no fitting solution.
Any ideas how to validate a datefield with adf/struts/jsp/bc4j?
Thanks for your help!
Torsten.

Torsen - In the first instance I'd recommed that you try and handle it declaritively using the Struts Validator Framework . See http://otn.oracle.com/products/jdev/howtos/10g/StrutsValidator/struts_validator_howto.html
There is a section in there on how to use the validator with ADF databound pages and you can check the format the user enters via generated JavaScript.
Also check out the matching sample project:
http://otn.oracle.com/sample_code/products/jdev/10g/ADFandStrutsValidator.zip - this has a data field check on it as well
