Include jsp containing a view object

I have a header jsf page which has a panelForm bound to a view object i created. Is it even possible to include this header.jsf which has a databound form into another (parent)jsf page? I'm getting errors when i try to include this header jsp using the <f:subview> tag.

any ideas on what i need to do to run the srdemo app? i'm assuming it's a db connection issue since when i try to run it i get an error message saying it can't find SRServiceLocal. The download/install of the db seemed to work fine, but for some reason the app isn't connecting. no big deal here, at least i've got the code examples to look at for help even if i can't run the app. also, the included menu piece you suggested looking at was not really what i had in mind with my jsp:include question. i was wondering if you could include a jsp(x) that had databound components (a table, for example) in it. does anyone know if this is possible?

Preventing the compilation of included .jsps

Hi,
          I am using WLS 5.1sp9
          We have the constraint of compiling our .jsps when weblogic is started, not
          at request time. And we need to use the include directive for some of the
          .jsps, as the included
          .jsps contains references to objects that are declared in the includeing
          .jsp, our included
          .jsps do not compile and that stucks weblogic initialization.
          Here is a simple example:
          a.jsp
          <% int toto = 123; %>
          <%@ include file="includes/myInclude.jsp"%>
          myInclude.jsp
          <b> <%= toto%><b>
          Of course myInclude.jsp cannot be compiled on its own, so we named it
          myInclude.inc, which works but is unelegant.
          Is there a way to still give the .jsp extension to the included file but
          prevent it from being
          compiled by WLS ?
          Cheers,
          Marc.


          No. Nothing more elegant that naming them .inc.

View object SponsorVwView does not include a primary key attribute RowId

Hi,
I have an Entity Object and a View Object which do not have a primary key. So I use a ROWID to act as one. The only thing is that sometimes I get this error which causes the application to fail on the server:
JBO-30003: The application pool (gov.fda.cber.pts.model.services.CberPtsServiceLocal) failed to checkout an application module due to the following exception:
oracle.jbo.JboException: JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: oracle.jbo.PersistenceException, msg=JBO-26028: View object SponsorVwView does not include a primary key attribute RowId of entity base SponsorVw.
Does anyone have any any ideas on this?
Thank you in advance

Hi...
I believe you'll need a PK so Oracle will know how to update the MV. Is there any particular reason for you not having a PK in FAFG_ASSETS table? As an alternative, you may want to create a new column in this table and having a table trigger/sequence populating this column.
But It looks like you are using EBS, so, I don't know if you can add new columns to tables.
See if this thread can help you:

Why this does not works??? (I use jsp: include. to contain two jsp files)

I have a main.jsp, and in this main.jsp, I have two part, leftButton.jsp and view.jsp, I want to include the leftButton.jsp and view.jsp to main.jsp.
The code of main.jsp is like follows:
<%@ page language="java" contentType="text/html" %>
<html>
<head>
<title>JSP include element test</title>
</head>
<body>
<table>
<tr>
<td><jsp: include page="leftButton.jsp" flush="true"></jsp: include></td>
                         <td>     <jsp: include page="view.jsp" flush="true"></jsp: include></td>
                    </tr>
     </table>
</body>
</html>
Why the include does not works? by the way, I embeded a flash.swf file in view.jsp.

Hi Mellon,
You might be better off using a JSPF segment for leftButton.jsp & view.jsp and the <%@ include file="relativeURL" %>.
Be careful that the included file does not contain <html>, </html>, <body>, or </body> tags. Because the entire content of the included file is added to the including JSP page, these tags would conflict with the same tags in the including JSP page, causing an error.
Note: It is conventional to put JSP segements under the WEB-INF/jspf/ folder so the file cannot be accessed directly by a URL
Note: JSPF files end with .jspf, so your files would be leftButton.jspf and view.jspf.

JSP, Data Web Bean, BC4J: Setting the where clause of a View Object at run time

Hi,
I am trying to develop a data web bean in which the where clause of a View Object will be set at run time and the results of the query then displayed.
My BC4J components are located in one project while the coding for the data web bean is in another project. I used the following code bu t it does not work. Could you please let me know what I am doing wrong?
public void populateOSTable(int P_EmpId)
String m_whereString = "EmpView.EMP_ID = " + P_EmpId;
String m_OrderBy = "EmpView.EMP_NAME";
oracle.jbo.ApplicationModule appModule = null;
ViewObject vo = appModule.findApplicationModule("EMPBC.EMPAppModule").findViewObject("EMPBC.EMPView");
vo.setWhereClause(m_whereString);
vo.setOrderByClause(m_OrderBy);
vo.executeQuery();
vo.next();
String empName numAttrs = vo.getAttribute(EmpName);
System.out.println(empName);
Thanks.

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by JDev Team (Laura):
Here is how I have usually done mine:
1. In the JSP, use a RowsetNavigator bean to set the where clause and execute the query.
2. Use a custom web bean to process the results of the query (print to HTML).
for example:
<jsp:useBean class="oracle.jbo.html.databeans.RowsetNavigator" id="rsn" scope="request" >
<%
// get the parameter from the find form
String p = request.getParameter("p");
String s = request.getParameter("s");
// store the information for reference later
session.putValue("p", p);
session.putValue("s", s);
// initialize the app module and view object
rsn.initialize(application,session, request,response,out,"wt_bc_WT_bcModule.wtjoinView");
// set the where clause string
String theclause = "presname = '" + p + "' AND slideno=" + s;
// set the where clause for the VO
rsn.getRowSet().getViewObject().setWhereClause(theclause);
rsn.getRowSet().getViewObject().executeQuery();
rsn.getRowSet().first();
%>
</jsp:useBean>
<jsp:useBean class="wt_bc.walkthruBean" id="wtb" scope="request" >
<%
// initialize the app module and VO
wtb.initialize(application,session, request,response,out,"wt_bc_WT_bcModule.wtjoinView");
wtb.render();
%>
In this case, the render method of my custom web bean mostly gets some session variables, and prints various content depending on the session variable values.
Hope this helps.

Laura can you give the code of your walkthru bean? i wna't to initialize a viewobject, set the where clause and give that viewobject back to initialize my navigatorbar.

What's the maximum number of view criteria that a view object can contain?

We are making extensive use of view criteria in our view objects, mainly for LOV purposes. Is there a figure on the maximum amount of view criteria a view object can contain.

How do I make a view object containing two entity objects updatable?

I have a view object that contains attributes from two entity objects. The query looks like this
SELECT AplCfgPartyEO.ID,
AplCfgPartyEO.ID_HRM_BRW_JOB,
HrmBrwJobEO.CREATED_BY,
HrmBrwJobEO.CREATION_DATE,
HrmBrwJobEO.ID AS ID1,
HrmBrwJobEO.ID_HRM_BAS_JOB_TYPE,
HrmBrwJobEO.JOB_NO,
HrmBrwJobEO.MODIFIED_BY,
HrmBrwJobEO.MODIFY_DATE,
HrmBrwJobEO.ORIGIN,
HrmBrwJobEO.PICTURE
FROM APL_CFG_PARTY AplCfgPartyEO, HRM_BRW_JOB HrmBrwJobEO
WHERE AplCfgPartyEO.ID_HRM_BRW_JOB = HrmBrwJobEO.ID
My problem is that I am only allowed to update the attributes from the AplCfgPartyEO entity object while the attributes from the HrmBrwJobEO entity object become read only. I want to be able to update all of the attributes how do I do that?

If someone will read this later I can inform them that I am using Studio Edition Version 11.1.1.0.2 at the moment. Thanks Chris, your answer solved my problem but I was a little surprised though that it wasn´t updatable by default.

Accessing View Object Information from JSP

Hi!
I know that my question it's a basic one, but I'm having some problems. Let me start by describing my problem.
I need to implement an navigation select box to one table (this table will be a result of a query). I'm "building" the select box with a <c:forEach> iterator. Well, the problem starts where:
<%-- Makes a kind of Math.ceil(double) --%>
<c:set var="resultInDouble" value="${(binding.estimatedRowCount-1)/binding.rangeSize +1}" />
<c:set var="resultInDoubleZero" value="${resultInDouble - resultInDouble % 1}"/>
<fmt:formatNumber value="${resultInDoubleZero}" var="resultInt" pattern="0"/>
<select name="select" >
<c:forEach var="SelectBoxItems" begin="1" end="${resultInt}">
</c:forEach>
</select>
As you can see, first I need to calculate the number of "<option> ... </option" I need to put on the select box, and I do that by making an ceil method emulation (for those that doesn't know ceil, it rounds up a division, like 7/3 = 3). To do this ceil I need to call the estimatedRowCount. And that's the problem: when I call estimatedRowCount, the query that I previous made is repeated to calculate the numberOfRows returned. As you can imagine, I don't want to re-execute the query, but only get the number of all rows.
One solution that I thought, was in the Java Controller File for this page, use the method associated with the ViewObject getRowCount(), that doesn't re-execute the query. With this idea, I would construct the select box with java code, something like this:
<select name="select" >
<%
int ceilResult = Math.ceil(viewObject.getRowCount(),viewObject.getRangeSize());
for (i = 0;i<ceilResult;i++) {
%>
<option> ... </option>
<% } %>
</select>
But with this idea, I hanged with a problem: "How do I in JSP, can "see" the view object?".
Basically i only need a small example source, that in Java Controller File can get the iterator to make the return of the ViewObject getRowCount method.
Does anyone have any idea how to solve this problem, or maybe a new approach ?
Tiago Soares
P.S. I've already tried some others (attempts of) solutions, but they didn't worked. I didn't posted their description, because I was afraid that anyone would read this post, because of the size of it. :)

First of all, please stop reposting this question. Post it once and someone will probably reply to it.
Secondly, you can expose methods of a view object through it's dialog (I think) or you will have to do it in the Application Module.. But it may suit your need better to create a transient column on you VO (one that exists only in memory) and store your value in that.

View Objects , whereclauseparam and PERFORMANCE in JSP

We experience that using the method setWhereClauseParam gives VERY BAD performance in our JSP applications.
According to JDev team and others, "best practice" is to use setWhereClauseParam(s), so we wonder why the performance degrade significantly compared to a simpler approach (=define the whereclause when the datasource is created). To avoid the shared pool to grow we were tempted to use the recommended best-practice-parameter-binding approach, but due to performance we had to drop that idea.
Our JSP (pseudo) code look like this:
<jbo:ApplicationModule id="am" .......
<jbo:DataSource id="ds" appid="am" viewobject="ourView" rangesize="0"/>
<%
ViewObject ourVo= ds.getApplicationModule().FindViewObject("ourView");
ourVo.setWhereClauseParam(0, 'xxx');
ourVo.setWhereClauseParam(1, 'yyy');
%>
<jbo:RowsetIterate datasource="ds" >
bla bla bla ..
</jbo:RowsetIterate>
THIS IS SLOW !! ..... compared to:
<jbo:ApplicationModule id="am" .......
<% String clause = "Col1 = 'xxx' and Col2 = 'yyy' %>
<jbo:DataSource id="ds" appid="am" whereclause='<%= clause %>' viewobject="LabelHeadersView" rangesize="0"/>
<jbo:RowsetIterate datasource="ds" >
bla bla bla ..
</jbo:RowsetIterate>
We get the same results but the last method is times 100 faster ??
Any ideas are appreciated .
Thanks, Jens

OK. I believe I now know what the culprit it. It is your use of the where clause fragment:
(pdk_files_id = ? OR ? IS NULL)
Here's how I arrived at this (while at the same time ruling BC4J out of the picture as a potential cause of the problem).
I following the steps below:
[list]
[*]Connected as SCOTT in SQLPlus, I create the table:
CREATE TABLE files( pdk_files_id NUMBER PRIMARY KEY, name VARCHAR2(20));
[*]I insert one row into the new files table:
INSERT INTO files values (1111, 'SteveTest');
COMMIT;
[*]I connect as SYSTEM, an run the script ORACLE_HOME/sqlplus/admin/plustrce.sql to create the SQL*Plus PLUSTRACE role so that SCOTT will be able to use the SQLPlus AutoTrace feature
[*]As SYSTEM still, I ran the command: GRANT PLUSTRACE TO SCOTT
This gives SCOTT the privilege to use the SQL*Plus autotrace command
[*]I connect as SCOTT, and run the script ORACLE_HOME/rdbms/admin/utlxplan.sql
this created the plan table in my SCOTT schema needed to run the autotrace feature
[*]In SQLPLUS, still connected as SCOTT I issue the command:
SET AUTOTRACE ON EXPLAIN
[*]Then I do the following to create a SQL*Plus bind variable
VAR v VARCHAR2(20)
[*]And then do the following to set its value at the SQL*Plus command prompt:
EXEC :v := '1111';
[list]
Finally, I try some different queries and look at the autotrace output:
SQL> select * from files where pdk_files_id = 1111
2 /
PDK_FILES_ID NAME
        1111 SteveTest
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE
   1    0   TABLE ACCESS (BY INDEX ROWID) OF 'FILES'
   2    1     INDEX (UNIQUE SCAN) OF 'SYS_C003006' (UNIQUE).
This shows that using the literal value 1111 uses the index.
SQL> select * from files where (pdk_files_id = 1111 or 1111 is null)
2 /
PDK_FILES_ID NAME
        1111 SteveTest
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE
   1    0   TABLE ACCESS (BY INDEX ROWID) OF 'FILES'
   2    1     INDEX (UNIQUE SCAN) OF 'SYS_C003006' (UNIQUE).
This shows that using the literal values together with the OR clause, still uses the index.
SQL> select * from files where (pdk_files_id = :v)
2 /
PDK_FILES_ID NAME
        1111 SteveTest
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE
   1    0   TABLE ACCESS (BY INDEX ROWID) OF 'FILES'
   2    1     INDEX (UNIQUE SCAN) OF 'SYS_C003006' (UNIQUE).
Using my ":v" bind variable I defined, it uses the index, too, even though the type of the bind variable is VARCHAR2 and the type of the PDK_FILES_ID column is NUMBER. This is because this is a simple enough case for the database to do automatic type coersion to convert my string value '1111' for the bind variable into the number value 1111 and then use that for the index lookup.
HOWEVER, when I try the case that simulates what you are doing in BC4J, which is using a bind variable together with the OR clause for the NULL test, we see...
SQL> select * from files where (pdk_files_id = :v OR :v IS NULL)
2 /
PDK_FILES_ID NAME
        1111 SteveTest
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE
   1    0   TABLE ACCESS (FULL) OF 'FILES'.
So in this case, the database DOES NOT use the index, and hence explains why your query is slow.
I believe the database works this way because when it hard-parses the SQL statement, it is at this time that it determines the query plan for the SQL statement. The plan needs to remain stable since the same plan will be cached and reused for all uses of the same parsed SQL statement, so the plan cannot be conditional based on the values of the bind variables. Since it cannot decide without knowing the value of the bind variable, it apparently disqualifies your index from being used.
Even introducing an optimizer hint only improves the problem a little. I tried this example:
SQL> select /*+INDEX (files sys_c003006)*/ *
2 from files where (pdk_files_id = :v or :v IS NULL)
3 /
PDK_FILES_ID NAME
        1111 SteveTest
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE (Cost=826 Card=5 Bytes=125)
   1    0   TABLE ACCESS (BY INDEX ROWID) OF 'FILES' (Cost=826 Card=5 Bytes=125)
   2    1     INDEX (FULL SCAN) OF 'SYS_C003006' (UNIQUE) (Cost=26 Card=82).
In this case it still has to fully scan the index where above it was able to do a unique scan.
MORAL OF THE STORY:The tiny cost of having two different View Objects in your application, one to use when you want to find by PDK_FILES_ID, and one to use when you want to find by your other key criteria, is well worth the performance improvement that can be had by using bind variables and using them in a way that the database will use the index.
As Tom Kyte says in his excellent book Expert One on One: Oracle in a passage that made me laugh:
"If I were going to write a book about building Oracle applications that do not scale, "Don't Use Bind Variables" would be the first and last chapter." :-)
So, by using a few design-time-created view objects that uses bind variables and avoid the use of the (COL = ? OR ? IS NULL) construct, you get the following benefits:
[list]
[*]The database doesn't have to hard-parse your SQL statement each time you execute it (which it does if you keep sending queries that have literal values in the SQL statement, making each query different as far as the SGA is concerned)
[*]The indexes will get used correctly as we saw above
[*]Your code actually might be clearer, since you can name one of your view objects "FindFileById" and the other one "FindFileByName", or what have you
[list]
Hope this helps.

Doing queries in view objects that do not include primary keys of entities

Is it possible to create a view object based on an entity that doesn't include the primary key from that entity object. For instance I want to do something like "select distinct (attrib1) from sometable" and obviously attrib1 is not the primary key for that table so I get an error that says, you must include a primary key in your view object. How would I implement something like this in bc4j?

You just need to go into expert mode and create the statement directly with the relevant SQL
e.g. in 9.0.3:
Context Menu -> New View Object
Select no entities in Step 2
Next through to Step 5 of the wizard and enter you expert mode SQL there. E.g. Select distinct deptno from emp
Assign the new VO to the AM data model and away you go.

Repeater fails using {container.item} context within included JSP pages

Greetings,
I'm using Bea Workshop 8.1.2 and netui's based framework.
I'm experiencing a problem relating to the use of jsp:insert tags as a way of templating the code as to make it more maintainable and cost effective.
The problem arises when using repeaters and then binding a <netui> tag with a "container.item" context inside the included jsp page.
Example:
On a PageController we define on its scope a rather simple data structure:
public String[] array={"Item1","Item2","Item3"}
The associated index is as follows:
index.jsp
<netui:html>
<netui-data:repeater dataSource="{pageFlow.array}">
<netui-data:repeaterHeader></netui-data:repeaterHeader>
<netui-data:repeaterItem>
<netui:label value="{container.item}"/><br>
</netui-data:repeaterItem>
<netui-data:repeaterFooter></netui-data:repeaterFooter>
</netui-data:repeater>
</netui:html>
This works as expected, it prints the data in the array list. Fine.
Now, with the <jsp:insert> tag usage, we get two files index.jsp and body.jsp:
index.html
<netui:html>
<netui-data:repeater dataSource="{pageFlow.array}">
<netui-data:repeaterHeader></netui-data:repeaterHeader>
<netui-data:repeaterItem>
<jsp:include page="body.jsp" flush="true"/>
</netui-data:repeaterItem>
<netui-data:repeaterFooter></netui-data:repeaterFooter>
</netui-data:repeater>
</netui:html>
body.jsp
<netui:html>
<netui:label value="{container.item}"/>
<netui:label value="{pageFlow.array[0]}"/>
</netui:html>
With this example the {container.item} tag fails with this exception:
"Caught exception when evaluating expression "{container.item}" with available binding contexts [actionForm, pageFlow, globalApp, request, session, appication, pageContext, bundle, container, url, pageInput]. Root cause: com.bea.wlw.netui.script.xscript.IllegalContextStateException: The Tag "com.bea.wlw.netui.tags.html.Label@cb5dce" does not have a valid parent of type DataAccessProvider. The expression "container["item"]" requires a parent of this type."
BUT - and here is my problem with this - the label tag with {pageFlow.array[0]} PRINTS THE DESIRED ELEMENT.
Also, on an extended example with a <form> tag around the main index html and the array structure inside a FormData class, {actionForm.array[0]} ALSO PRINTS THE DESIRED ELEMENT.
Only {container.item} gloriously fails with an exception complaining about IllegalContextStateException.
This is a total nonorthogonal behaviour, the features do not work as expected and indeed, with the importance of repeaters for netui's development, this preclude us from the minimum standard for structured web application design.
Does anyone have any clue about this behaviour? If not a fix, at least an explanation...
Thanks in advance.

I am trying to insert multiple rows I when submited I am get ting only 1 row in the DatabaseForm.
my netui.log file shows this error:

The actionForm uses a FormData which has a Array of all the fields that need to be populated.
Any idea why only 1 row shows up ?.

JSP, View Object and ? parameter

I have a view object that uses a ? type parameter in its query. The use ? type parameter checkbox has been marked in the view and the view compiles successfully.
Now this view is being used by the Data Web bean JS Tree Browser in a JSP page.
The JSP code
<jsp:useBean class="oracle.jbo.html.databeans.JSTreeBrowser" id="roleMenuTree" scope="request" >
<%
roleMenuTree.setDepthLevel(6);
roleMenuTree.setReleaseApplicationResources(false);
roleMenuTree.setDisplayAttributes("Name");
roleMenuTree.initialize(pageContext,"Tasksys_TasksysAppModule.MenuTreeView");
Object x[] = new Object[1];
x[0] = "tasksys";
roleMenuTree.getRowSet().getViewObject().setWhereClauseParams(x);
roleMenuTree.getRowSet().getViewObject().executeQuery();
roleMenuTree.render();
%>
</jsp:useBean>
But I end up getting the following error. WHY ?
Error: 500
Location: /tasksys/jsp/login_submit.jsp

You need to prepare the query using the setWhereClauseParams(x) call, before you initialize your data web bean. Otherwise, if you call the methods after you initialize your web bean, the context has already been set and the error occurs.
You should insert another data web bean into your page somewhere at the top and use it to setup your query and create a view object. You should remove this bean's Render() method since you are only interested in the Initialize() method here. Add your code to prepare the query and create the view object.
Then when your JS Tree Browser executes, it will be able to call getRowSet() on the View Object you created already.

Can Designer generate ADF Entity Objects, View Objects and Apps Module ?

Hi all,
On what way can Designer integrate with JDeveloper (+ ADF) ?
Can Designer generate ADF Entity Objects, View Objects and Apps Module ?
Thank you for your help,
xtanto

Designer itself has no direct integration with JDeveloper. However, there are three options. First of all, you can get a JDeveloper extension (download this separately) that lets you create a Connection to a Designer repository. From that Connection you can find modules that you defined in Designer and generate Entity and View objects for the tables and columns that you used in those modules, and an Application Module. It does not create JSPs or other user interface objects.
Another option is to buy JHeadstart from Oracle. This contains a set of code generators and ADF extensions that include an ability to get information from a Designer repository. JHeadstart works fine for non-Designer users too, but was built by the same people who wrote Designer Headstart - they know the repository API intimately.
The third option is to download Oracle Designer Extension Builder (ODEB) which was just recently made available. This is a product of a collaboration between Designer users from the Oracle Development Tools Users Group (ODTUG) and Oracle to extend the capabilities of Designer with user written tools and utilities. You could use ODEB to write your own generators for ADF Business Components. Or you could wait and see if someone else in the user community does this. I hope that you or whoever does such a generator will be willing to share it with us all.

Possible?Multi-Entity View Object with one Entity Object that is Read-only.

I know this sounds crazy, but I would like to create a multi-entity view object, where one entity object is based on a table in my application (we'll call it "Users", which basically stores the primary key for the person from the institutional people database), and the other table is a entity object based on a view of the institutional people database table (read only access), which we can call "People".
I know that since no updates will be done to the People table, it really should be a read-only View Object, but I would lose the ability to sort on attributes like Last Name, Hire date, etc, since those would be transient attributes in my ViewObject for the Users. By having People as an entity object, I can then create a multi entity view object and have the ability to join Users to People and be able to sort on the above mentioned fields (like Last Name).
The problem is that when I use the JDev (I'm currently using 10.1.2.1) AppModule BC4J tester, when I click on the multi-entity view object that I added to the AppModule it gives me an error:
oracle.jbo.RowCreateException) JBO-25017: Error while creating a new entity row for People.
----- LEVEL 1: DETAIL 0 -----
(java.lang.InstantiationException) null
I have tried to change all the attributes to updateable in my entity object, but no create method, and I have tried to make them all read-only, but no effect, I get the same error (probably because the People view is read-only in my schema).
Is there a way to change the entity object so that it will not try to create a new row when it runs the Tester? So that the multi entity view object behaves more like a view link, but gives me the added bonus of being able to sort on the Last Name column from the People table?
Thanks for any help on this subject...at worst, I will have to use the view link method to get the job accomplished, but it would be "cooler" if this would work!
Jeremy.

Steve, thanks for your quick response to my question.
To answer your questions, I was trying to create the Multi-entity View Object to give me more flexibility when working with my User table, and my People view. The flexibility I desired was that I would be able to sort my Users based on attributes in the People view. This is not possible when the there is only one Entity in my VO, and the People view data are all transient attributes, because they are not in the SQL statement.
Ultimately, after working with one of my colleagues, we decided to use the approach that you mentioned by creating a read-only VO with the SQL query we want to display to the user (contains both User and People data fields), and then use a different ViewObject when performing other actions on the User Table (such as inserts/updates/deletes). By using the setWhereClauseParam() method in the handleLifeCycle() for the JSP page, we should be able to navigate between the different View Objects, so that the user does not see any difference.
Thanks! Oh, and by the way, I have read your article you included before, and I have used it many times before to tune my View Objects! Thanks!
