Problem Removing CMP 2.0 Bean from Many side of One-to-Many

I'm getting an exception within the weblogic container when I try to
delete a bean from the many side of a one-to-many CMR.
The two entity beans are called CaseFile and CaseExpert. There are
many CaseExperts for each CaseFile. When you call the remove method
on the CaseExpert, Weblogic throws a null pointer exception when
accessing the EntityCache as shown at the bottom of this message. I'm
using the latest version of Weblogic 7 (WebLogic Server 7.0 Thu Jun
20 11:47:11 PDT 2002 190955). My relationship section of my
ejb-jar.xml file is also shown below.
Any ideas?
Thanks,
David

Hi,
I like to do the following:
1) Map one bean corresponding to table A to many beans corresponding totable
B 2) table B has two columns as the primary keys.
3) One of the primary key column in table B is a foreign key pointing tothe primary
key of table A.
4) bean corresponding to table A has the cmr Collection field
I am not able to map this scenario. I guess the mapping is possible aslong as
each table has its own unrelated primary keys. If anyone has tried this,please...please...help.

How call session bean from Client side

Hi
calling session bean from client side it gives Lookup erroe, it gives JNDI error
how we know session bean is working. in Admin tree bean statis is reb Flaf, and ID is "Down" how we activate it..
null

If you can make a connection using sess_sh, then you know that you have configured your database and listener properly. If it is not working, read the manuals that you can download from technet. They are pretty good, and if you follow the directions, you should see success.
Good Luck!

How-to remove a jsf backing bean from session?

How can I find the reference to a backing bean (with session scope) and then remove the bean?
I may have painted myself into a corner. When most of my pages are navigated to, they get key info from session and then initially populate the page fields. I populate the fields in the constructor with values from the database based on the keys found in session. So the second time a particular page is called the values may be stale or completely unrelated to the page navigated from because the bean already exists and, naturally, the constructor is never called.
I'm thinking if I could remove the backing bean, jsf wouldn't find it so it would be recreated on subsequent navigations. Since the constructor would be called with every navigation to the page, the values would not be stale or unrelated.
Any help would be greatly appreciated.
TIA,
Al Malin

Problem in calling single entity bean from other beans

Hi,
I am implementing session facade with SUN's J2EE 1.3 deploy tool for JBoss server.
I have a entity bean UserBean which creates users in database ( create() )and tells if user exists or not ( findByPrimaryKey() ).
Initially, I had implemented UserBean with remote interfaces. So, any servlet ( my client ) which needed to use UserBean would make a remote call to it. It was used by 5 different servlets.
Now I am going for Local interfaces. So, I am packaging UserBean with other beans which need it.
Problem is, if I package UserBean with , say , ChatLogsBean ( Stateless bean ), it works fine. But when I package it with WebLogsBean ( Stateless bean ) also and deploy all beans together, JBoss gives error messages that instances of UserBean are already created.
How should structure my beans sothat I can avoid these duplication problem ?
Present flow is as follow:
Servlet Stateless Bean Other beans
ChatLogs Servlet --> ChatLogsWrapper --> ChatLogsBean ( Stateless bean ) & UserBean( Entity bean )
WebLogs servlet --> WebLogsWrapper --> WebLogsBean ( Stateless bean ) & UserBean
WordLogs servlet --> WordLogsWrapper --> WordLogsBean ( Stateless bean ) & UserBean
All servlets are packaged into corresponding WARs.
ChatLogsWrapper , ChatLogsBean ,UserBean are packaged into 'ChatWrapper' JAR.
WebLogsWrapper , WebLogsBean , UserBean are packaged into 'webWrapper' JAR
and similarly for WordLogs.
Any help ?
Regards,
Suraj

I suggest you post to one of the forums on jboss.org. There should not be a problem AFAIK having remote and local interfaces to the same EJB. I assume that you gave these unique names (FooHome/FooLocalHome..etc...) for the home and remote interfaces and declared both in the ejb DD.

I need help recovering the DOWNLOAD ICON from the side bar thing

i don't know how but the download was gone from the side bar one day, i guess my parents did something accidentally and took it off. But i don't know. is there any way for me to get that icon back on the side bar?

To your other post - where is the home folder - - it's the little house in the Finder sidebar with your username after it.
Yanda the panda wrote:
but the download folder is completely gone from everywhere
it only pops up a window when i download something
That is not the downloads directory - that's the Safari local Downloads window. Not the same
Now, are you saying that the real Downloads directory has been removed - deleted?
Click on that home folder - the house icon and look carefully for a Downloads Folder. It should look like this:
If you do not see it, perhaps it was moved.
In the Finder search window, enter downloads. Select "This Mac" and "File Name" and see if it pops up.
If not, do you have a backup? TM or something else?
If not, we can create a new Downloads folder but alas, everything in the original is gone.

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.persist(order);
session.getTransaction().commit();
session.close();
I can see Order and Order Line are get persisted but Order Line table don't have order_id populated automatically. Please help me out.

That is because you're not setting it, obviously. Nowhere in your code are you actually populating the order property of the orderlines.

One to many shuffle

Hi Guys
I want to know how do we save the data from one table to another as soon as the user shuffle the things in one to many shuffle
this one to many shuffle is done based on selection of Radio group
When user select a radio button as per that the data will be displayed in one to many shuffle below
what I want is When the user shuffle the things which he wants then it should immediately go and save in another table based on primary keys
How can I do that???
Any suggestion is Appreciated
Thanks ,
Santosh.

You can have af:switcher component to display ADF Form and ADF table and based on your value of Radio button hide/show the facet

CMP Beans from Tables: Why does the Container try to create new tables?

I'm trying to develop an EJB application using JDeveloper on 9iAS. I have several CMPs and have my tables that I want my CMPs to be based on already defined in my DB schema. I want to use CMP but I don't want the Container to create the tables, rather I want the Container to map my CMP EJBs to the already existing tables.
The issue is:
While creating these CMP EJBs in JDeveloper I chose the "New Enterprise Java Bean" EJB creation wizard using the option labeled "Container-managed Entity Beans from Tables". My assumption is that this does what I want, because the wizard prompts for a schema and table you want to map to. Then it creates the attributes & getter/setter methods, PK class, etc. all based on the table defintion automatically. Great. So why when I try to run my application do I get error messages for each EJB such as:
Auto-creating table: create table STREET_TYPE (PK_STYP_ID NUMBER(8), STREET_TYPE VARCHAR2(20), primary key (PK_STYP_ID, STREET_TYPE))
Warning: Error creating table: ORA-00955: name is already used by an existing object
Huh?? I thought the idea is that the CMP EJB is mapped to the existing table in my schema. Why is the Container trying to create new tables?? Is this possible? Or am I missing something fundamental about how Containers create and manage CMPs? Or is this just a JDevelop container issue? TIA

I presume you are getting the problem on application
deploy? This happens when upon initialization of the application using the built-in OC4J container/app server that is part of JDeveloper. Here is the full messaging:

Create CMP Entity Beans from Tables Wizard - Can't see any tables with DB2

Hi,
I'm trying to use the "Create CMP Entity Beans from Tables Wizard" to create an entity from a table in a DB2 database. The problem is, on page 2, I can't see any available tables. I have verified that the connection works (I can open the connection in the Navigator frame and I can see that table).
Note that if I try this wizard on an Oracle database, I can see tables.
WTF? Can someone please help?

I second the motion. I too work in an environment with centralized data management (DBA's) that create and maintain all tables under a generic schema. This has prevented me from using the Create Entity Beans from Table feature of Jdev r3 preview.
At least I can see that I'm not alone.
Thanks
When I select the "Create CMP Entity Beans from Tables Wizard," no tables or views are available to select. The JDev database connection is using an ID assigned to me.
The tables that I am looking for were created by the DBA under his ID and are therefore in that schema. He did create Public Synonyms for them, but the tables still do not show up in the wizard.
Is there a configuration step that I need to do to have those tables show up?
Tables created by a DBA and then accessed by developers using a public synonym is a very common scenario and should be supported by JDeveloper (IMO).
Thanks.
I'm using JDev 9.0.2.8.2.

How to remove Bean from session upon leaving the web page?

Hi...
I got the following problem
I promote a user with a Datatable filled with data, each time the user enters the webpage with the table I go the DB and retrieve all relevant data again (so each time the user gets an OnLine representation of the DB)
to archive that I defined the bean that pulls data from DB in Request scope. and it worked well... but now i added an option to export the table into Pdf made by a servlet.... now to be able to get the bean from the servlet i had to change the scope of the Bean to Session Scope... and all works fine.. BUT... now the page not showing OnLine representation of the DB.. cause its only created once , cause its inside Session Scope...
My question is how can I remove the Bean from Session scope upon the user leaving the page (I don't want to remove the bean from session scope on the next called bean of the other page) i want to remove the Bean upon leaving the current web page... Or maybe force the constructor to be executed each time the Page is loaded (as if it was a Request scope bean)....
Any ideas?
Thanks ahead!
Daniel.

Hi,
When you are moving to another page, you are performing an action right ?
(i mean the request moving to Server side), if you do so, then clear the bean object values list.
for example :
private List<Integer> intList = new ArrayList<Integer>();
public void clear()
intList.clear();
or
store a new object in session, when ever u moved to the second page, so that the old object will be no longer
in use, so it will be garbage collected.Regards,
Sathya.

Check that there isn't a different Trash folder to the one with the proper Trash symbol on it.

EJB 3.0: CMP Entity bean from view

Hi,
I have created an entity bean from a database view.
I don't have a good filed to use as id in my view. So I want to generate the id in my entity bean.
How can I do this ?
Thanks

Hi,
I didn't get your question.
CMP is something, which can be done by hand.
So maybe it is better, to do it manually.
Bea has some workaround, I am sure.
Maybe it is something with deployment descriptors, which
have to be configured to the underlying database.
Sorry for my stupid first answer.
Volker.
