JDEV 10.1.3 EJB 3.0 Is it a way in JDev to monitor the sql generated

Is it a easy way to monitor/log the sql generated by top link (ejb 3.0 with top link as cmp) directly in JDeveloper (embededd oc4j)

Deleting the bean class sources from JDev don't delete the compiled class and the wizard will add a sequential number to the entity bean name and source file. This is not very convenient. As workaround you will have to delete the class file.

JDev9i-Beta;How could I run two JSP applications in Jdev enviroment at the same time?

Hi,
I have two JSP applications located on different directories. I wanted to run both applications at the same time in Jdev enviroment. But the second one failed.
More info:
I successfully ran Application1, then minimized the browser and ran Application2, then again minimized the second browser. After I maximized the first browser(Application1) and tried to go thro pages, I received page not found. Because Jdev sat up the Class Path for the newer application(Application2) and looks for pages there. I believe thats why I could not run both at the same time. How could I get around of this?

hi,
can you provide more details on this. Are these jsp files part of the same project or different projects. I can not duplicate this issue. Please provide us more information.
Thank you

How to make JDev aware of the xmldb API

Hi everybody,
I am a real beginner in Jdev, and I have to develop a
Java Application using Oracle Java developer, against
an XML-native database called eXist. I'll have to use
a java API called xmldb supported by eXist in order to
interact with the database. Although I have basic
knowloedge in Object-oriented programming, but I don't
know where to begin, especially how to make JDev aware
of the xmldb API, and how to create classical
application components (Windows, buttons, etc).
Could you help me with some orientations and
interesting links?.
Thanks a lot.
Mounir.

Hi,
don't know this database, but the database vendor should be able to explain how his DB is accessed from Java. If this requires libraries, then the vendor will provide these in JAR files, which you then configure with JDeveloper (as a custom library Tools --> Manage Libraries) or in the Project
If there is a JDB driver for it, even better. This however is not a deliverable of JDeveloper but the database vendor

Whether java component (Not ejb, not servlet) can be deployed in App Server and get the services provided by App Server

As I mentioned in subject, I am just wondering Whether the java component (Not
ejb, not servlet) can be deployed in App Server and get the services provided
by App Server or not?

Nevermind folks - I got it to work. All my configuration was correct; I had other issues with the ejb-jar file that the verifier informed me of (my previous deployments were with the verifier turned-off).

To JDev Team : SQL generated, Struts, BC4J Admin, ...

Hi,
I've followed the Tutorial 'Generating a Struts-based JSP Application for an
Application Module', where I'm working with only one table.
When I run the 'main.html', on the left side ( navigator ), there are 'Browse' and 'Query' options.
Every time I click on 'Browse', I always have this error :
Error Message: JBO-26044: Error while getting estimated row count for view object TimesheetView1, statement
SELECT count(1) FROM (SELECT Timesheet.ts_id, Timesheet.ts_user, Timesheet.ts_code, Timesheet.ts_date, Timesheet.ts_hour
FROM timesheet Timesheet) ESTCOUNT
My config are :
* Win2K
* JAVA_HOME set to j2sdk1.4.1_01
* mySQL 3.23.49 with JDBC driver mysql-connector-java-2.0.14-bin.jar
* I use ultraDevHack=true as parameter within the URL
Even with 'ultraDevHack=true' parameter, the subselect still not working.
I've seen in the forum that JDev Team have tried with that parameter, and it worked,
but it didn't mention with which version of mySQL and which JDBC driver.
I would like to modify the above SQL into a simpler one 'SELECT COUNT(*) FROM timesheet'.
Anybody know how ?
The View Object Wizard didn't help me at all for the above SQL.
In fact I would like to fully controled, modified, or cuztomised all SQL generated.
Back to main.html, the header contains two buttons 'BC4J Admin' and 'Help'.
When I click on 'BC4J Admin', I have this :

Why is that ?

Any of you have the same problem ?
Is it possible to put some criterias within the Search, i.e. Sort by Date ?
Any help would be appreciated.

Does Jdev 11g Provide the Introspection feature?

Hi Everyone
Does any one have the idea whether Oracle Jdev 11g supports the Introspection Design pattern?
My Requirement is like I have two DTO's(Data Transfer Objects). The Source DTO has 100 attributes approximately. I need to have a feature/framework something like that it takes two DTO's and transfer the data from Source DTO to Target DTO and returns the targetDTO as output.
I have seen this reature in Struts Framwork (org.apache.commons.beanutils )
Thanks in Advance

Why don't you just use the beanutil code?
This is nothing specific to jdev, is just java. One other way is to write this feature yourself using reflection.

Do you have any space in jdeveloper workspace directory ?
i.e C:\Document and settings like path.
Also mention the default integrated domain's path.
If any space is present then create a new domain and workspace without containing any space and run your application.

Pages run from Local JDEV is showing the DEV instance login

Hi,
When I run the page from my local jdev it is showing me the DEV instance login page.
Not sure why..I have been using the JDEV for the develpoment of custom application (OA) since last 8 months.
This is the first time I am getting this problem.
Please help
Thanks
Anna

Have you renamed your system recently? This happens because the properties file may still have old system name, the problem should be resolved by deleting system folder.Also please make sure that your system name should not have null spaces, i remember this problem with jdev 9i.

HOWTO: get JDev to show the foreign keys in Conn Nav & struct window

Hi,
I have SQL tables with foreign keys but the JDev connections navigator and table editor dont show them. They just look like primary keys in the "PK" column. The structure window shows a bunch of constraints with names like "SYS_C00143114" which is not very meaningful to me. Surely JDeveloper knows what these magic numbers mean and can trace the foreign keys for me.
How can I get JDeveloper to show the foreign keys, and which table is referenced by that foreign key? Can I make it navigate from a table's foreign key value to the the correct tuple in the referenced table?
Maybe this is an ER if JDev doesn't do this already. Navigating a schema, or drawing it showing all the foreign key references would be very handy. Navigating through actual table data would be nice too.
Cheers,
Simon.

I found "new->Database Diagram" that does a lot of what I wanted, at least in mapping out the foreign key references. Now if I can just figure out how to print a .png file...
It would still be nice for the connection navigator to trace them also.

Cannot capture the exception generated by EJB components.

Hi, All:
I got a strange problem when developing EJB application under SAP WAS server. I developed an EJB as below:
public class UserAccountBean implements SessionBean{
     String getUserEmail(String accountID) throws SAPSystemException{
          if(error){
               throw new SAPSystemException("Specified user not found.");
Exception I defined as below.
public class SAPSystemException extends Exception {
@param message
     public SAPSystemException(String message) {
          super(message);
In client side I code as below:
public String getUserMail(String accountID){
     UserAccount bean = home.create();
     try{
          String email = bean.getUserEmail(accountID);
     }catch(SAPSystemException e){
          // do something here;
     }catch(Exception e){
          // do some other thing here;
It is strange that the SAPSystemException I throw out in the bean cannot be caught by the block catch(SAPSystemException e), it is only captured as general exception and it is said as UndeclaredThrowableException.
When I deployed EJB components and Web components together, the exception can be captured successfully. But when I deployed them separately, it has problem for exception capture. I think it must be the protocol problem. Before I only use RMI-IIOP but SAP WAS server using RMI-P4. Is anything I can do to solve this problem?
I packed the remote and home interface for the EJB and common classes like value objects and exceptions in both components. Is there anything I forgot to set for the deployment?
Thanks in advance.

Thank you very much Gregor. In fact, I already defined this throws exception in the remote object interface.
public interface UserAccount extends EJBObject {
     public String getUserEmail(String accountID) throws RemoteException, SAPSystemException;
This is application-specific interface and this mechanism works well in my previous in other application server.
I checked the SAP document and found if you using RMI-IIOP, you need to get the client package for your deployed EJBs and put in the path accessible by the WEB components. Based on this suggestion, I put the EJB jar file together with WEB application (Sure the EJB application still deployed in other host and JNDI point to that host. I remembered one book mentioned that if you don't want generate the client package from EJB containter, you can do it this way. For me, I just haven't found the way to get the client package with Administrator Tool it said.), It works!!!. I checked the remote object generated by home object, it is different with EJB jar file there or not. But in the document SAP said that only if you use RMI-IIOP you need do this way, for RMI-P4, you don't need that. Anyway, it seems that RMI-P4 use same way as RMI-IIOP(You only don't need narrow the home object after lookup).
I'll try to find how to get EJB client package from WAS server. For this is my first time to use SAP WAS Server, things a little strange.
Thank you very much for your great help.
Cheers.

VO Query runs very slow in jdev, quickly in Toad/SQL Plus

Hi,
I am trying to create a search application using JSF with ADF BC. I have a VO based on a SQL query, which joins two tables. The search criteria is referenced using bind parameters in the VO.
In Toad, SQL Plus, and SQL Developer, I can run my VO query and the results return quickly, within a couple of seconds. An Explain Plan indicates that all indexes are being correctly used. However, when I try to run my search form (exact same query) in jdev, it executes extremely slowly - almost 5 minutes before a result set is returned. My VO query is below.
select oea.order_yr,
oea.order_type,
oea.order_key,
oea.max_rev,
oeo.profit_center_id,
oeo.contract_total_price,
oeo.complexity
from oe_admin oea,
oe_order oeo
where oea.admin_id = oeo.admin_id
and oeo.profit_center_id = :ProfitCenter
and oea.order_yr = nvl(:OYear, oea.order_yr)
and oea.order_type = nvl(:OType, oea.order_type)
I've been messing with this for several days and I'm out of ideas. Does anyone have any suggestions?

The question is not whether the query uses a viewLink but rather do you have any other views that are linked to this view - if you do have such views you might want to check the setting for whether children are retrieved as well.
Also run ADF BC in debug mode to see the exact query that is being sent to the server and check out the explain plan for that one.

Monitoring the connection state of an EJB

Hi, as far as I know and read about EJB, a SFSB is connection oriented. I have a rich lcient connectiong to a SFSB and I want to monitor this connection. In case of lost connection (e.g. because of timeout) I'w like to react on this event.
Does anyone know whether this is possible?
Thomas

I dont think this could be done, but if you can explain exactly what needs to be done somebody can look into this.

Retrieve the jdev project from the ear file

I have an ear file, but I've lost the original jdev project.
How can I retrieve the project from the ear file?
I would know if there's a function in jdev or with another tool to convert an ear file to the original project in jdeveloper.
Thanks.

Try the File->Import menu option.

How to view the sql queries generated by EJB (CMP)

Hello,
I'm using Oracle9iAS (9.0.2.1.0) Containers for J2EE (build 020827.1652) & Oracle 8.1.7 database.
I have a CMP that has about 400 fields and the corrsoponding table has about 800 fields. I'm able to call create and add a row in database.
Now when I call update method to set the remaining fields of this row (I get the proper instance by calling findByPrimaryKey()) I'm getting an exception ORA-00957 duplicate column name.
I'm using reflection to set all the fields by passing my update method a HashMap and setting those fields that this HashMap contains. And as HashMap cannot contain duplicate keys the possiblility of having duplicates is eliminated.
But why am I getting ORA-00957 duplicate column name.
Is there a way I can configure somehow to view what sql query is being generated by the OC4j container when its firing this query to update the database table.
Any help will be greatly appriciated.
Vipin.
