Dynamic re-creation of Entity/View Objects
Does anybody know if the following is possible with JDeveloper/ADF, and if so, any suggestions on where to start?
My boss wants to be able to re-define a series of database views dynamically at any time, adding/removing columns. This will be handled by PL/SQL etc so it is not part of the JDeveloper question.
But he then wants the J2EE Swing GUI application to be able to "see" the changes to the view immediately e.g. to display new fields on the client form, without having to re-compile any code.
The Swing GUI appears to be a given, unfortunately as it would be easier to re-create at least the GUI dynamically using JSP etc.
Right now, I'm trying to figure out how to pass the database changes through the J2EE tiers e.g. how do I dynamically re-define the Entity Object based on the modified view, without re-compiling it? How do I reflect these changes in the corresponding View Object(s)?
Personally I think this requirement will be the death of the project, as it will absorb 95% of our limited intellectual/Java resources for 5% of the functionality: Welcome to Dilbertland!
But given this requirement, does anybody out there have any ideas?
Thanks,
Chris
Hi Chris ,
well you can always create dynamic attribute in the view object using viewObject.addDynamicAttribute(DynamicAttributeName);
and you can store any serialazable object in this attribute like any other attribute. It should be serializable coz BC4J needs to send it to Database in case you are using spillover feture
to cache records.
you can also create Dynamic view object based on an entity or a SQL query.
AppModule.createViewObjectFromQueryStmt();
But of course dynamic view based on SQl Query
will not be updatable. I doubt , You can dynamically create attribute on Entity or dynamic Entities.
I have already posted one question for this ..and waiting for reply ..:-(
Updatable , Dynamic VIEW OBJECT ??
hope it'll help

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! -
Updating a Multi Entity view object to add row only to child entity
I have a View object VO1 made of multiple entities e.g. EO1 and EO2 which have a composition association with cardinality 1 is to many EO1 being the entity corresponding to parent table and EO2 is the child table. All the entities in the association are updatable.
The data is displayed using VO1 on the page. So for each row in child table, parent table attributes are dispalyed correctly due to the join condition.
If I create a new record on the VO1 iterator using the create operation binding and save it, it correctly saves a new record in header table and related child table.
Now I need to provide with one more create operation on the page such that when user can add a child row for the existing header row using the same screen.
Essentially I need a create operation which, on selecting a row from the displayed table which is based on VO1 , creates a new row in the VO1 iterator such that the EO1 attributes are pre filled with the header table information from the selected row and the child attributes can be added by the user and submitted.
Tried Using create with params on VO1 by passing the header information, this lets me enter the data on screen just the way its required ,but this obviously only tries to add a new record to header table with the existing primary key itself and the operation fails on save giving duplicate key error for the header table.
Unable to figure out where to change the default behavior to fetch a exisitng entity rather than create a new entity in the header table entity object for this multiple entity VO1.Hi ,
So how do i send in the sample. Do i send in the code base don HR schema ..
Or just explain the above with emp dept tables. -
View link creation on two view objects, and both view objects are populated program(not from sql)
I have master and detail VO , both views data is loaded in program. Now for show/hide feature, I create View Link Object and using one element from both child and master VO , View Link Object created properly.
But I can not able to add that view link object into AM.
Now because of that , I cannot say what is a instance name of that view link object.
Hence getting following error -- Invalid or missing view link. Please attach view link with the bean.

Issues in persisting dynamic entity and view objects using MDS
Hi All,
I'm trying to create dynamic entity and view objects per user session and to persist these objects throughout the session, I'm trying to use MDS configurations(either file or Database) in adf-config.xml.
I'm facing following two errors while trying to run the app module:
1. MDS error (MetadataNotFoundException): MDS-00013: no metadata found for metadata object "/model/DynamicEntityGenModuleOperations.xml"
2. oracle.mds.exception.ReadOnlyStoreException: MDS-01273: The operation on the resource /sessiondef/dynamic/DynamicDeptEntityDef.xml failed because source metadata store mapped to the namespace / DEFAULT is read only.
I've gone through the following links which talks about the cause of the issue, but still can't figure out the issue in the code or the config file. Please help if, someone has faced a similar issue.

//////////////////////////////////////////////////////////////////////////////////////////////////////////Hi Frank,
I m trying to save entity and view object xml by calling writeXMLContents() and saveXMLContents() so that these objects can be retrieved using the xmls later on.
These methods internally use MDS configuration in adf-config.xml, which is creating the issue.
Please share your thoughts on resolving this or if, there is any other way of creating dynamic entity/view objects for db tables created at runtime.

How to build a full dynamic WHERE expression in ADFBC Faces View Object ?
Dear Steve
>
I need an example about how to build a full dynamic WHERE expression in
ADFBC View Object
In UIX I known to do that, but i don't kwown how to do in ADFBC Faces.
please help me to see an example.
thanks
Juan CarlosYou write an AM level method to set the where clause and you expose it as a client method. (just like you did before)
Then you can drag this method onto a page as a button and then pressing on this button will execute the method.
If you want this to be done automatically without pressing a button - you go to the pagedef.xml file for your page and add a methodInvocation binding to that AM method, and then add a method executable to the executables section calling this method. -
Possible bug when creating multiple detail view objects
using jdev 11.1.1.0.0 to build jsf/adf applications. I wanted to report what seems like a bug in 11g. I have a parent table which has two child tables. After creating the appropriate entities, associations, views, and view links, the app module looks like this:
MasterView
--DetailView1
--DetailView2
The two detail view objects are on the same level, they are both direct children of the Master view.
Here's what's happening:
1) I create the master entity/view objects (MasterView)
2) I create one of the detail entity/view objects (DetailView1).
3) I create the association and view link to establish relationship between MasterView and DetailView1. Everything works fine.
4) I create the entity/view objects for second detail view (DetailView2)
5) When I attempt to create a second view link (based off an association) to establish the relationship between MasterView and DetailView2, the query clauses of the Create View Link wizard (screens 4 and 5) do not get created properly. I finish the wizard and save. Not only does this view link not get created properly, but in the process the query clauses that were defined in the first view link between MasterView and DetailView1 are wiped out. This will break any coordination between master and detail views in both the app module tester and runtime. Has anyone seen this problem?fyi, it looks like this issue has been resolved with jdev 11.1.1.0.2 (Update 2)

Changing SQL Query in View Object during runtime
Hello everyone,
I've got some problems with view objects which I dropped on my JSP page.
1.)
What I want to do is changing SQL query during running my application. I have view object based on select query: "SELECT * FROM DEPARTMENTS". And after clicking button (or something else) I want to change the query: "SELECT * FROM EMPLOYEES" and I want to see this changes in my JSP page. Setting the query and executing it doesn't work. How can i do it?
2.)
I want to create view object programmatically, but I don't know exactly how many columns / attributes it will have. If I know the names of the attributes it's ok, but i don't know it... So I've got function, its body is:
Row rowForInsert = this.createRow();
this.addDynamicAttribute("ParamName");
rowForInsert.setAttribute("ParamName", "asda");
this.insertRow(rowForInsert);
but this code doesn't work (I can't see any changes on my JSP Page).Thank's a lot!
But there's another thing to do which I can't deal with.
I want to create view object in one jspx page, a I don't want to move to another.
And this method doesn't work.
What can I do?
I've got following error (I'm using dynamic table, when I create view object first time it's ok, but when i want to create another, there's execption):

Dynamic View Object Creation and Scope Question
I'm trying to come up with a way to load up an SQL statement into a view object, execute it, process the results, then keep looping, populating the view object with a new statement, etc. I also need to handle any bad SQL statement and just keep going. I'm running into a problem that is split between the way java scopes objects and the available methods of a view object. Here's some psuedo code:
while (more queries)
ViewObject myView = am.createViewObjectFromQueryStmt("myView",query); //fails if previous query was bad
myView.executeQuery();
Row myRow = myView.first();
int rc = myView.getRowCount();
int x = 1;
myView.first();
outStr = "";
int cc = 0;
while (x <= rc) //get query output
Object[] result = myRow.getAttributeValues();
while (cc < result.length)
outStr = outStr+result[cc].toString();
cc = cc+1;
x = x+1;
myView.remove();
catch (Exception sql)
sql.printStackTrace(); myView.remove(); //won't compile, out of scope
finally
myView.remove(); //won't compile, out of scope
//do something with query output
Basically, if the queries are all perfect, everything works fine, but if a query fails, I can't execute a myView.remove in an exception handler. Nor can I clean it up in a finally block. The only other way I can think of to handle this would be to re-use the same view object and just change the SQL being passed to it, but there's no methods to set the SQL directly on the view object, only at creation time as a method call from the application module.
Can anyone offer any suggestions as to how to deal with this?I figured this out. You can pass a null name to the createViewObjectFromQueryStmt method, which apparently creates a unqiue name for you. I got around my variable scoping issue by re-thinking my loop logic.

ADF BC: range paging on dynamic view object
hi!
i have a dynamically generated sql query and i want to get the results one page at a time. for this to work i create at runtime a view object and try to use range paging:
String sql = "SELECT ...";
ViewObject vo = appModule.createViewObjectFromQueryStmt("tmpVO"+System.currentTimeMillis(), sql);
vo.setRangeSize(pageSize);
vo.setAccessMode(RowSet.RANGE_PAGING);
vo.scrollToRangePage(pageNo);
vo.getEstimatedRowCount();
Row[] rows = vo.getAllRowsInRange();
vo.remove();
but when i run this it was pretty slow. so i traced the database session and saw that the executed query was the sql string, not the range paging select (SELECT * FROM (SELECT /*+ FIRST_ROWS */ IQ.*, ROWNUM AS Z_R_N FROM (...).
i use range paging on other view objects that are not dynamically generated and it works fine. please tell me what can i do to get only the specified page from the data base.
thank you
Edited:
here is the select i run:
SELECT UnitEO.UNIT_TYPE, UnitEO.UNIT_NR,
UnitTypeEO.USER_UNIT_TYPE,
UnitEO.UNIT_NR UNIT_NUMBER,

PS: I am using JDev 10.1.3.36.73You have a couple of choices. You could create one view object with a bind variable parameter(s) and in the application module you have 10 instances of that VO with appropriate values set for the bind variable in each instance.
Or if you are using the LOV feature of a VO then you can set an attribute to point to one VO and then using a view cirteria applied to that specific LOV you can then "filter" the data that would appear in that LOV.
Does that help?

Updatable , Dynamic VIEW OBJECT ??
Hi ,
I want to create a dynamic VO which is updatable.
I dont have any information about the table on which my View Object is based on, at DESIGN TIME. At run time I create query for the view and create dynamic view using AM.createViewObjectFromQueryStmt(String, String) but this kind of view will not be an updatable view.
I think if I use createViewObjectFromQueryClauses() from entity, it will be updatable,,,but in that I will have to create entities for all the table in my schema ..which sounds BAD...
is there any thing as DYnamic Entities ??
or any other trick to do this.....
BC4J should support something like changing QUERY_DATA_SOURCE_NAME at runtime in oracle forms.. which allow you to update record.
Thanx,
PrasoonHi Prasoon,
Steve Muench's "Dive Into BC4J" page has the following example: http://radio.weblogs.com/0118231/stories/2003/07/15/creatingUpdateableMultientityViewObjectDefinitionsDynamically.html
But this is based on pre-defined Entity Objects. It might give you some ideas, though.
Good luck!

Dynamic view object loses bind variables after passivation
I am creating a view object definition/view object programmatically in Jdev 11.1.1.2.0. The query requires a named bind parameter. All was working fine but now I am testing with app module pooling disabled and the bind variable is not being restored after passivation -- it's like the definition has disappeared or something.
Here is my VO creation code:
ViewObject vo = findViewObject("FinalistsWithEvalDataVO");
if (vo != null){
vo.remove();
ViewDefImpl voDef = new ViewDefImpl("FinalistsWithEvalDataVODef");
// I add a bunch of viewAttrs here...
voDef.setQuery(fullQuery);
voDef.setFullSql(true);
voDef.setBindingStyle(SQLBuilder.BINDING_STYLE_ORACLE_NAME);
voDef.resolveDefObject();
voDef.registerDefObject();
vo = createViewObject("FinalistsWithEvalDataVO", voDef);
vo.defineNamedWhereClauseParam("Bind_SchlrAyId", null, new int[] {0});
vo.setNamedWhereClauseParam("Bind_SchlrAyId", new Number(1)); //For testing
vo.executeQuery();
The query executes fine right there and then the VO seems to passivate fine. I even see the bind var in passivation:
<exArgs count="1">
<arg name="Bind_SchlrAyId" type="oracle.jbo.domain.Number">
<![CDATA[1]]>
</arg>
</exArgs>
But then when it reactivates prior to rendering the page, it invariably throws a missing parameter exception and this in the log:
<ViewUsageHelper><createViewAttributeDefImpls> [7409] *** createViewAttributeDefImpls: oracle.jdbc.driver.OraclePreparedStatementWrapper@1af78e1
<ViewUsageHelper><createViewAttributeDefImpls> [7410] Bind params for ViewObject: [FinalistsWithEvalDataVO]AwardViewingServiceAM.FinalistsWithEvalDataVO
<ViewUsageHelper><createViewAttributeDefImpls> [7411] ViewUsageHelper.createViewAttributeDefImpls failed...
<ViewUsageHelper><createViewAttributeDefImpls> [7412] java.sql.SQLException: Missing IN or OUT parameter at index:: 1
I have worked on this for hours and can't see anything wrong. Like I said, it works fine when not forcing passivation...
Any help would be appreciated.
Thanks.
-Ed@Jobinesh - Thanks for the suggestions. I have read all the documentation I can find. Everything works fine without passivation. Everything still breaks with passivation. I have given up on trying to get the bind variable to restore after passivation and am currently just building the query with all values embedded in the query rather than bind variables. This is bad practice but avoids the problem. However, now that I avoided that obstacle, I'm on to the next issue with passivation of this dynamic view object, which is that the current row primary key apparently cannot be reset after activation. I get the following error:
<Key><parseBytes> [7244] Key(String, AttributeDef[]): Invalid Key String found. AttributeCount:1 does not match Key attributes
<DCBindingContainer><reportException> [7254] oracle.jbo.InvalidParamException: JBO-25006: Value 00010000000A30303033383133343734 passed as parameter String to method Constructor:Key is invalid: {3}.

at oracle.jbo.Key.<init>(Key.java:179)
at oracle.jbo.server.IteratorStateHolder.getCurrentRowKey(IteratorStateHolder.java:34)
at oracle.jbo.server.ViewRowSetIteratorImpl.activateIteratorState(ViewRowSetIteratorImpl.java:3877)
I've been trying various workarounds for over a day now with no luck. Very frustrating.
Thanks for trying to help.

Error in Creation of a New View Object from Existing Entites
I define a Complex JOIN in the expert mode of the View Object Creation Mode. On trying to access the VO, the system returns an error, unable to creat View Objecy.
THe SQL Statement begins with
SELECT * from ( select ...My actual Query)
Is it possible to define ur own view objects with the same flexibility as the Data TablesHi Saket,
Following will be required for created a custom business object.
1. Object Type - ZTEST (Internal Techincal Key)
2. Object Name - ZTESTNAME (Technical Key Name)
3. Name - TEST (Name of BO, it is used while selecting the object type)
4. Description - (Short Description of BO)
5. Program - ZTESTPROGRAM (ABAP program in which the methods of the object type are implemented)
6. Application - A or B.. etc (Area to which your BO is related)
Please remember that you can learn these basic things by giving F1 help on those fields and in HELP.SAP.COM.

Two View Objects & One Entity Object
Has anyone ever had it where they create a row from a view object, set some attributes, insert it into that view object, and it shows up in another view object (as well as the one the row was actually inserted on)? Both of these view objects are using the same single entity object, it's just that their where clauses are slightly different. When I do a commit and then executeQuery, all is good and the new row only shows up in the intended view object.
Here is the code in my app module to do a row insertion on one of the view objects.
public void addQCNote(int userID, Number theStudyID, String theNote)
try
//StudyFtsViewObjImpl freeTextVO = getStudyFtsViewObj();
StudyFtsQCOnlyViewObjImpl freeTextVO = getStudyFtsReadOnlyViewObj();
freeTextVO.setWhereClauseParam(0, theStudyID);
DBSequence freeTextTypeCode = null;
StudyFTSQCCodeValueViewObjImpl freeTextCodeValue = getStudyFTSCodeValueViewObj();
freeTextCodeValue.executeQuery();
Row[] freeTextCodeValueCurrentRowArray = freeTextCodeValue.getAllRowsInRange();
// There SHOULD only be one ... but if there is more, pick one - geeez.
for (int i = 0; i < freeTextCodeValueCurrentRowArray.length; i++)
Row currentFTRow = freeTextCodeValueCurrentRowArray[0];
freeTextTypeCode = ((DBSequence) (currentFTRow.getAttribute(StudyFTSQCCodeValueViewObjRowImpl.CODEVALUE1)));
Row freeTextRow = freeTextVO.createRow();
// Sets up default values for insertion into db at commit time
freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.PARENTENTITYID, theStudyID);
freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.PARENTENTITYNAME, "STUDY");
freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.FREETEXT, theNote);
freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.FREETEXTTYPECD, freeTextTypeCode);
freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.CREATEDID, new Number(userID));
freeTextVO.insertRow(freeTextRow);
freeTextVO.setCurrentRow(freeTextRow);
catch (Exception ex)
System.out.println("Exception in AR3MainAppModule.addQCNote: " + ex.toString());

Uix two view-objects on one entity-object synchronize
Hi All
I want to add some uix pages to an old project using ADF UIX and Business Components.
I have an entity object to a table witch about 50 fields.
Now I create two view objects due to a better performance. One witch seven attributes for the overwiew and one with all attributes for the detail page.
They are related via a view link.
I create the overview as a read-only-table and the detail-page as an input-form.
The proplem is that the synchronization don't work. The detail page shows the first dataset ever.
Has anyone a solution or a tip where I can found that?
Is where a performance problem if I use one view-object for both pages?
Thanks in advance
RogerUse custom DataAction for the first page:
package controller;
import oracle.adf.controller.struts.actions.DataAction;
import oracle.adf.controller.struts.actions.DataActionContext;
public class Class1 extends DataAction
protected void validateModelUpdates(DataActionContext actionContext)
//super.validateModelUpdates(actionContext);
// put you custom validation here
}http://www.oracle.com/technology/products/jdev/collateral/papers/10g/ADFBindingPrimer/index.html#usingdataaction

In terms of performance. Which adapter works better ? ADC-VGA or DVI -VGA
Or are parameters different ? Presently my CRT 20" Sony requires an adapter for my G4. My graphics card suggest that I can add another monitor. It will be a LCD with DVI output. Is the performance better from the ADC-VGA option for the CRT ? Thanks
