Problem when trying to delete CMP entity bean
Hi,
When I try to remove a CMP entity bean, I have this error :
re09.projet_ejb.syndic.AdminException: Exception thrown from bean; nested exception is: javax.ejb.EJBException: nested exception is: com.sun.jdo.api.persistence.support.JDOUnsupportedOptionException: JDO76207: Update of a primary key field is not allowed.It's only happening when I try to remove a bean which has a relation with another bean. The relation type is One to Many. I tried to search on this forum to find an answer but I found nothing that could help me.

Sry I just found the mistake, the cascade delete was not on the right place :s

Got it sorted so I thought I would share the solution here: The problem wasnt related to LR 5.2 but was to do with Mac OS X 10.8.5 AKA Mountain Lion. I had also noticed that I was having an issue around deleting anything on my MAC. When I tried to delete a file from anywhere I was asked to submit my password. The message I got was finder wants to make a change please submit password. I checked through the mountain Lion forums and found a solution here; https://discussions.apple.com/message/20499360#20499360%2320499360
I implemented it and the problem has dissappeared.

Problems accessing fields in a CMP entity bean from a session bean
Hello everybody,
I'm getting the next problem: when I try to access a field in a CMP entity bean that I have instantiated from a session bean (trhoug entitybean.getNameOfField), I get the error "the entity bean does not exist in the database".
This entity bean is accessing a table in an external database (not the DB of the WAS), but I know that it's getting the correct data from the table, since I check the entitybean.size() and the entitybean.findByPrimaryKey(), and I get the right information. For some reason, the only thing that it doesn't work in the entity bean are the getter/setter methods (I created them automatically after having created the entity fields).
I access the entity bean through its local interface...
I know it's really difficult to give an answer with so few details, but... does anybody think I forgot something important to configure??
Thank very much in advance!!
Isidrogetter and setter methods for cmp-fields are abstract.
getter and setter methods for cmr-fields are abstract.

Hi:
Which method in a CMP Entity bean should be abstract? just only SetXXX
and
GetXXX?
Thanks!

can anyone suggest me on howto solve this problemI suspect that there is a type mismatch somewhere in the CMP fields (there is a ClassCastException in the trace).
Please check the generated code (UserBean1689033004_JDOState.java line 969) that can be found under

Problem when trying to delete rejected files in LR 5.2.
When I try to delete rejected files I enter the library module, select all photographs by their rejected flag status and using the cmd and backspace keys, I get the usual message offering me the options of canceling, deleting from the disk or remove from catalogue. Choosing delete from disc I then get a pop up window that says there were (x amount) of files that could not be moved to the trash folder. It does this whether I try to delete all images flagged as rejected at the same time or go file by file and delete them in ones and twos. I am using a mac. The trash folder is empty.
Got it sorted so I thought I would share the solution here: The problem wasnt related to LR 5.2 but was to do with Mac OS X 10.8.5 AKA Mountain Lion. I had also noticed that I was having an issue around deleting anything on my MAC. When I tried to delete a file from anywhere I was asked to submit my password. The message I got was finder wants to make a change please submit password. I checked through the mountain Lion forums and found a solution here; https://discussions.apple.com/message/20499360#20499360%2320499360
I implemented it and the problem has dissappeared. -

CMP entity beans from tables in 9.0.3 jdev preview
I am trying to generate CMP entity beans from oracle tables using 9.0.3 jdeveloper preview. My oracle db version is 9.2. I notice that if a table has a single column primary key, no xxxPK.java file is created. However, if the primary key is multi-column an xxxPK.java file is created. Is this correct behavior? I expected an xxxPK.java file to be created regardless of the number of columns in the primary key for the table. Has anyone else noticed this? I am new to EJB so forgive my ignorance.
Comparing to JDev 902, I think this is a much better decision. Having to change beans with a single field PK to not using a custon PK class, to avoid using that class was a pain in JDev 902. There4s little benefit in using a custom class when there4s only a single field in it... some will say that it prevents having to do majot changes to your code if the PK changes in the future and add another field. But a careful database design will void this almost completely. So having JDev 903 use a java native class is a better option in this situation. At least from my personal point of view.

Error in deploying CMP Entity Beans
Hello,
When I created a CMP Entity Bean using the JDeveloper Release Candidate and try to deploy it I get the following message:
Auto-creating table: create table POGROUP_PRESS_RELEASE (press_release_id integer not null primary key, press_release_date varchar (255) null, title varchar (255) null, time varchar (255) null, release_type varchar (255) null, URL VARCHAR2(100))
Warning: Error creating table: ORA-00955: name is already used by an existing object
What does this mean? Does it mean that this bean cannot be deployed. If the table already exists in the database shouldn't it use the table instead of trying to create the table?
Any help would be appreciated,
Gopiinitialize "table" attribute of <entity-deployment> element to POGROUP_PRESS_RELEASE.This will prevent auto-create functionality of OC4J.
However this <entity-deployment> tag present only in orion-ejb-jar.xml.So you have to create this file and include along with ejb-jar.xml in jar file.
Sample orion-ejb-jar.xml looks like this....
<orion-ejb-jar deployment-version="1.0.2.2" deployment-time="ea013a2eda">
<enterprise-beans>
<entity-deployment name="TestHome" location="TestHome" wrapper="TestHome_EntityHomeWrapper5" table="POGROUP_PRESS_RELEASE" data-source="jdbc/OracleDS">
<primkey-mapping>
<cmp-field-mapping name="m_ID" persistence-name="ID" />
</primkey-mapping>
<resource-ref-mapping name="jdbc/OracleCoreDS" />
</entity-deployment>
</enterprise-beans>
</entity-deployment>
</orion-ejb-jar>
For complete DTD :
http://xmlns.oracle.com/ias/dtds/orion-ejb-jar.dtd
Hope this helps.....

Do I must include orion-ejb-jar.xml in my CMP entity bean?
Deal all:
I've had a problem about deployment of my CMP entity bean.
I don't know if I need to include orion-ejb-jar.xml in the jar
file? Could anyone tell me what files I should include them in
jar file and what config file(like data-sources.xml) I should
modify them?
Thanks!!The orion-ejb-jar.xml is not necessary...oc4j/orion auto-
generates this configuration file when the application is
deployed. You would only need this file if you are using o-r
mapping, or changing some deployment time option with your ejb.
The config/data-sources.xml file is used by the container. If
you are using oracle, you will need to use the data-sources.xml
for your database (the path needs the proper database name, and
server host, and you will need to put in the password and
username). Use the example with the oc4j docs to help you, or
the one already in your config directory.

Error when trying to delete a vendor from SC
Hi all,
I am encountering a problem when trying to delete a vendor from a contract and assign preferred vendor.
The messages are
"Enter exactly one partner of type preferred vendor"
"Partner data couldnot be determined".
In BBP_PD, I find two entries in partner table with partner_fct = 39.
I am also not able to delete one of this entry.
Please suggest.
Thanks
NandalalHi Nandlal,
Can you see the business partner nos correctly for the vendors you are trying to assign?
Are these vendors assigned to pur org?
DO you get all greens in BBP_BP_OM_INTEGRATE?

ORA-01407 when removing a CMP Entity Bean with WLS 9.1
Hi all !
I hope you can help me to solve this ?:|
I'm migrating my application from WLS 8.1 SP3 to WLS 9.1.
I'm getting now an SQLException when I try to remove a CMP Entity Bean.
The stacktrace is as follows:
java.sql.SQLException: ORA-01407: cannot update ("USER"."MY_TABLE"."THE_CMR_FIELD") to NULL
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:145)

at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:3498)
at weblogic.jdbc.wrapper.PreparedStatement.executeUpdate(PreparedStatement.java:128)
Of course, I replaced the table and column names above to be more readable ;-)
The table MY_TABLE has a CMR field called THE_CMR_FIELD. The column is not nullable in the database (by the way, it's an Oracle 9i).
Everything is fine under WLS8.1
I tried two different Oracle JDBC drivers (9.2.0.5 and 10.2.0.1.0), but the result is always the same within WLS9.1.
Any ideas or suggestions (or even questions) are more than welcome!
Thanks

</pre>
In fact I have this setup:
<pre>
workpattern 1..n workpatternday -| 1..n dayperiod
| 1..n daycoreperiod
</pre>
And before 'ejbRemove'ing the workpattern I first remove the days and before that the periods and core periods.
I start with the periods and instead of removing them in the DB he tries to update the FK to the day with '' (p6spy result).
When I remove the not null constraint on the foreign key everything passes to the day where the workpatternId cannot be set to null.
He does not throw errors on the coreperiod (where the not null constraint to day is still present).
When I invert the sequence of deleting
(first the core periods then the 'regular' periods) he complains about the dayId on the core periods table.
So it's completely absurd :S
I hope weblogic 8.1 might solve this problem as this development code is still to be migrated to 8.1 before going in production...
I would just like to know what's wrong. There are other places with just about the same relationships (CMR and DB) where he does not complain... -

How to use same transaction when calling CMP entity beans and DAO (JDBC)
We are currently using Weblogic 8.1 SP2 with an Oracle 10g database (using XA thin and non-XA drivers).
We have a session bean that invokes an entity bean and a DAO (data access object pattern) in order to add data in 2 separate tables (account and history). Rows are added to the first (account) table using a CMP Entity bean while inserts are done in the 2nd (history) table using a DAO. Here is some pseudo code:
addHistorySessionBean (trans-attribute="Required")
begin
Step #1 - call addAccountEntityBean (trans- attribute="Required")
Step #2 - call addHistoryDAO (get datasource, connection)
end
The 2nd table (history) has a foreign key constraint to ensure that the corresponding key exists in the first (account) table. Unfortunately, DAO inserts on the 2nd (history) table fail with a foreign key constraint violation (INTEGRITY CONSTRAINT VIOLATION - PARENT KEY NOT FOUND!) since they cannot see the row added to the 1st (account) table in step #1 by the CMP entity bean.
How does one ensure that all this is done in a single transaction ? It appears that the app server creates two seperate transactions (one for the session bean facade and the entity bean and a 2nd transaction (when we retrieve a connection using the same data source JNDI name) for the DAO.
A post on server side suggested using a "<resource-ref>" in the session bean to tie the two potentially separate transactions together, but that does not work for us. However, I am not sure if we are doing that correctly. After we define the resource ref in the session facade bean, do we use the resource ref "name" attribute to lookup the datasource or do we still lookup the datasource by JNDI name ? Do we need to define the resource-ref tag in the entity bean also ?
Does Weblogic allow using a single transaction for this type of a scenario ? How does one specify within Weblogic that the same transaction should be utilized by the entity bean and any subsequent DAOs?
People have also suggested that we defer constraint checking until the transaction(s) are committed but that sounds like a work acount without addressing this issue. Would postponing the constraint checking in Oracle cause any additional overhead ?
Any suggestions with specific examples or documentation on how to address this issue will be gratefully appreciated.Thanks for your suggestion. Unfortunately, this does not work since it appears that there are 2 separate transactions going on here. One, the original one initiated by the session bean and used by the entity bean and the other initiated by the DAO. Any other ideas appreciated.
Hi,
Try setting the delay-database-inserts tag to
ejbCreate in RDBMS descriptor file.

CMP Entity Bean's problem with MS-SQL Server 2000
Hi everyone!
I have a problem regarding CMP Entity Bean on OC4J.
I made one CMP Entity Bean and deployed it to OC4J.
It was successful.
I used MS-SQL Server 2000 as Datasource.
So, I installed MS-SQL Server's JDBC Driver and add some jar files to classpath.
And I updated 'data-sources.xml' in OC4J's config directory.
Then, I updated also 'orion-ejb-jar.xml' in my application's directory.
I changed data-source's name to my data-source's name which use MS-SQL Server 2000.
Finally, I started OC4J and EJB Client program which called Enitiy Bean's create method.
But, The error occured which was 'Database error: java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]LINE 1: '.' Wrong sentence'.
What's wrong? I need any helps.
Here is stack overflow message. Thank you. Best regards.

From the information you have supplied, my guess is that the SQL
string that OC4J is sending to SQL-Server is incorrect. So it may
help if you could see the exact SQL string. In order to see the
SQL string, I suggest you either run OC4J in "debug" mode, or try
using "P6 Spy".
The following web page has details on running OC4J in "debug" mode:
http://kb.atlassian.com/content/atlassian/howto/orionproperties.jsp
And here is the web page for "P6 Spy"
http://www.provision6.com/
And these other web sites may also be of help (in general):

Error while using sybase trigger with the CMP entity bean,ejb version 2.1
Hi All,
I am using ejb version 2.1 and using entity bean (Transaction required) ,i am trying to update data in sybase(ver 12.3) database table
I am using session bean(Transaction required) to update the multiple entity beans in a while loop.It is working fine .But when i am trying to run it with the trigger which updates multiple tables in different sybase databases on update of each entity.Then it throws NoSuchEntityException and it rollback the whole transaction.
My trigger has only few simple update statements and the trigger runs fine without my CMP entity bean.is the CMP does not support the update triggers in sybase or is it the problem with the transaction.
Please help
Thanks
AnshuIf you can have a look at a cmp example in the samples that ship with the server. My guess is that the weblogic-ejb-jar.xml file is missing the <persistence-use> element which for 810 would look like:
<persistence>
<persistence-use>
<type-identifier>WebLogic_CMP_RDBMS</type-identifier>
<type-version>7.0</type-version>
<type-storage>META-INF/weblogic-cmp-rdbms-jar.xml</type-storage>
</persistence-use>
</persistence>
I seem to recall that the elements might be slightly different in structure for the wls700 version of the DTD, so please check that (I cannot, I'm at home and don't have everything here).
Give that a try and see if it doesn't solve your compilation failure.
Also, the compilation should not be throwing a null pointer exception in a case like that, I consider that to be a bug.
