Keeping Entity EJBs synchronized with Database

Is it possible that container managed persistance takes care of synchronizing entity beans' states with database record even if there is some external non-Java application that changes the state of the records straigth at database?
For example:
1. I map CMP entity bean to a database table's row and query it's state from J2EE client
2. I modify some data releted to that particular bean in the database: change some values by command line (SQL+ at the case of Oracle) on the row in the table in the database
3. I query again the same bean's state
Now, is the state I will get at the section 3 the same I got at section 1? If so, then CMP hasn't synchronized the bean's state and I get wrong value when reading it at second time.
Can I automatize this synchronization task some how? This is very important issue when trying to take J2EE architecture in use on old legacy database systems which still have their own non-J2EE clients running.

So if the entity bean is not used in a transaction it's state will not be re-read from the database, correct?There is no such thing.... if you invoke an entity bean in an unspecified transaction context I believe the spec defines it as a non-deterministic situation but in general the state will be re-read(but why would you want to do that?).
Has the container do a database query for each read of B bean state?This is a vendor specific issue.... it depends on your EJB container provider, I know some vendors have all kinds of configurations to optimize these situations.
Which are all the situations when an entity bean's state is (re-)read from the database?In general the state will be re-read at the first time a bean is invoked in a single transaction, but vendors offer a lot of mechanisms to configure all kinds of "sunchronization strategies".
Do you really mean that every time I read a bean's state it will be the same with the database?
Is there any exceptions? The important thing to notice is that we have to assume that state of the database
changes all the time by non-J2EE legacy clients. You should be able to control this with the locking mechanisms(as mentioned before) that your container and RDBMS provides. in your situation, it sounds like pessimistic concurrency control would be appropriate.

Mapping of an entity EJB to multiple database tables using CMP?

Can one entity EJB have attributes split between (mapped to) multiple databse tables?
Would CMR work properly between two such entity EJBs (both mapped to multiple database
tables).

Hi Milos.
Can one entity EJB have attributes split between (mapped to) >>multiple databasetables?
A CMP Entity should be always mapped a record in a single DB table.
Thanks.

Cannot 'Synchronize with database' my entity objects

Hello,
I have successfully created entities in my model using the 'new buisness components from tables' function. But now my database moddel has changed and I would like to synchronize my entities with database to get newest colums, but when right clicking an entity, the 'Synchronize with database' link is greyed and cannot be selected.
I have a database connection configured in my application resources and I can still import new tables in my project.
Do you have any idea of what is happening? This is not the case for all my applications. I can still synchronize in some other ones
Thank you for your help
Stephane

Synchronize with the database will be avaialble for the Entity Object
I think there is a problem with the particular entity that got created when you did the business components out of tables..
This is not the case for all my applications. I can still synchronize in some other onesif this is not happening with any other EO in any other application.. then you can try
recreating the EO from the table..
compare what is the change in between the EO that can synchronize and your current EO that cannot synchronize..
another option might be to check the application.. if that is havign some hidden property to synchronize..
last is to go with sameer's approach, to doubt about the table is not proper... in the same applciation create an EO with another table and try to synchronize.. you will get to actually the point where there is a problem..
good luck.

Session EJB vs ENtity EJB

Why/When would you use Session EJB instead of Entity EJB to access Database values

You might use a Session Bean to access the database when you didn't want the overhead of Entity Beans or if the data you were retrieving didn't relate to the entity structure easily.
Have a look at the Fast Lane Reader pattern in the J2EE Design Patterns section to get more information about an example. Here the data is only being read and presented to the user so support for updating the values, security and concurrency isn't needed and is purely overhead.
Hope this helps.

Database Views with Entity EJBs

Is it possible to use Weblogic Workshop to create a CMP entity EJB on an Oracle database view for a Weblogic 8.1 server?
Is there special configuration I need to do for either the Oracle or Weblogic side to accomplish this?
Thanks.
Tania

I can manually create the EJB, an it builds just
fine, but when I go to deploy it, I get the following
error:
[EJB:011076]Unable to deploy the EJB
'AssortmentMerchandise' because the databas
e table 'K_BA01.BAV_ASRT_CLUSTR_DAT' is not
accessible. Please ensure that this
table exists and is accessible.
The view is on the same datasource that I have
successfully created all of my other entity EJBs
(from tables).
I can select data from the view using JDBC and the
same datasource that I am trying to associate the EJB
to.
Any ideas what might be wrong with my view?Are you using synonyms or aliases? I would double check those...
Log in using same username and password as weblogic and try a simple query:
select * from K_BA01.BAV_ASRT_CLUSTR_DAT

How to use the same Entity EJB to access the same table in 2 syb databases

We are trying to convert an application to J2EE. We have the following
concern. The application requires the use of 10 sybase databases with
identical tables. One database per branch. We would like to be able to use the same set of entity EJBs to access all databases.
One solution we can think of is to use bmp entity beans and have a dispatcher session bean pass the database that the entity bean has to connect to.
Would it work?
Is there a more elegant way to do this?

I don't know if there is a more elegant way to do it, but that will work. I have a similar scenario, one database per customer. You'll have to use BMP and get your connections based on the branch.
Each one of my DAO methods requires that a customer ID be passed in for each method. The customer ID is part of the primary key for each entity bean; therefore, if I need to find a deposit (entity) for a customer, I pass the customer ID and deposit ID to my session facade, create the PK using these, do a findByPrimaryKey, etc. In the ejbLoad, I use the customer ID and the deposit ID to pass into the DAO. There, another class (ConnectionFactory) returns a proper connection based on the customer ID passed, which I use to do my queries.

CMP Entity Bean with database specific features

Hi there,
I�m studying Entity Beans and I'm doing some experiences with SQL Server.
At first, I built a CMP Bean and marked in deploytool to create the tables. Ok, it worked.
Now, I'm trying to interact to an existent database. But, I got a problem: the primary key is defined by the Server. I can read it and I can remove entries. But, when I try to insert some entry, I can't pass the key in SQL statement. I edited the generated statement to do it, but it doesn't work. I get a RollbackException.
My question is: is it possible to do what I'm intending to do with CMP? What am I doing wrong?
Do you think that, to do this, I should use BMP Entity beans?
Thanks in advance,
Anicio

"CMP provides you with database independence and less coding efforts."
BMP is not database dependent, unless you invoke database specific things in your SQL (something I do not do). CMP on the otherhand is inherently appserver specific (which was it's goal when BEA, IBM, et al. came up with it), and still limits your design possibilities. See this thread for an example:
http://forum.java.sun.com/thread.jsp?forum=13&thread=318785
As for less coding effort, that is a relative statment. Yes a simple CMP bean requires less coding to develop the first time. I personally view a few lines of SQL to load and store the data as being fairly trivial. But that needs to be offset with the problems inherent in using appserver specific CMP implementations.
As an example, try mapping WebSphere CMP to a pre-existing database without using IBM's IDE. It's an incredible pain in the ass since WebSphere does not come with a "meet-in-the-middle" solution. Any J2EE developer that has had the experience of working with different appservers (especially if they have had to port an app, as I have) can attest to the complications that arise with each implementation.
A BMP bean, written with non-DB-specific SQL, is the most portable, most flexible approach to EntityBeans. Yes, it requires the developer to be able to write some SQL, which should not take a significant amout of time. WRT queries, you have to write them, either SQL, EQL, or some appserver specific format.
As an aside, the use of code generators to simplify the creation of EJBs lends itself well to BMP. By using a (or writing your own) code generator, you can mitigate the annoying SQL bugs that creep up early in development.

Oracle Dabase Schema with OC4J CMP Entity EJB

I have tables in a schema called vsxlib. My Entity EJBs that map to SQL SERVER tables (no schema) work perfectly. My Entity CMP EJBs that connect need to connect to the vsxlib schema only partially work.
The findAll method works. When I add a where clause, I get no results back.
When I try a findByPrimaryKey, I get a ObjectNotFoundException.
Does OC4J version 9.0.3 support database schemas? There were examples posted at http://otn.oracle.com/sample_code/tech/java/j2ee/javacookbook/transactionsample/readme.html#descfiles say that they have an Entity bean working within a db schema.
Could it be permission related????
I even tried creating a synonym pointing to the table within the vsxlib schema.. No Luck.
I had this same problem with JBoss3.2 and found out that they did not support db schemas. That is why I was wanting to switch to OC4J because I thought for sure, being an oracle product that it would support db schemas.
Any help is greatly appreciated.

Hi Alex,
I think you may be misunderstanding the meaning of 'database schemas'. For your information, in the Oracle database, a schema is the same as a database user. For example all the database tables belonging to user SCOTT (TIGER) are said to be in the SCOTT schema.
OC4J uses the term 'database schema' differently. Here it refers to the mapping of database datatypes to java classes. Look at the "j2ee/home/config/database-schemas" subdirectoryof the OC4J installation for more details. The "data-sources.xml" file has a 'schema' tag (not sure if that's the correct name) which points OC4J to the datatype mapping XML file -- usually one of those that come with the distribution. However, I use OC4J stand-alone version and I don't need to worry about the mappings at all -- OC4J already knows the mappings for an Oracle database (I assume).
In order to access a particular Oracle schema, I merely have to log in to the database as the appropriate user. So, using the previous example, if I configure the "data-sources.xml" file to use 'scott' as the database login, then OC4J can access the SCOTT schema. You can find more details about Oracle's use of the term 'schema' in the Oracle documentation, which is available from:
http://tahiti.oracle.com
Hope this has answered your question.
Good Luck,
Avi.

Problem with database schema objects in the entity object wizard

Hi All,
When creating a new entity object, I am facing a problem with database schema objects in the entity object wizard, database schema objects (check boxes for tables,synonyms...) are disabled. Actually I am using a synonym but I am not able to select the synonym check box.
Can any of you folks tell me how to enable the database schema objects (check boxes for tables,synonyms...).
Thanks in Advance.

Synchronize with Database on Entity Object re-creates Association

hi
Please consider this example application created using JDeveloper 11.1.1.4.0
at http://www.consideringred.com/files/oracle/2011/MovedAssociationApp-v0.01.zip
It has an EmpManagerFkAssoc Association which has been moved from the "movedassociationapp.model.entities" package to the "movedassociationapp.model.assoc" package (using the "Refactor - Move..." context-menu option).
When selecting "Synchronize with Database..." in the context-menu of the Employees Entity Object, and clicking the "Synchronize All" button, this results in JDeveloper re-creating the EmpManagerFkAssoc Association,
as shown in the screencast at http://screencast.com/t/l7jaoU2C
- (q1) Is this Association re-creation intended behaviour (if so, please explain, if not, which bug number)?
many thanks

Ferez,
have you seen this thread in the ADF forum, Cannot 'Synchronize with database' my entity objects ?
It mentions the existence of a bug that may cause this (though no reference number), and one user posted a workaround they were using.

What id shows at the bottom of the Featured tabs in the App Store apps on the two devices ? If they still show your account id then try tapping on the id and log out of it and your wife can then try logging in with her account.

Entity EJB deployment on Oracle through JDeveloper 3.2

I have a project which is using Oracle 9iAS as the for the web server. There were intial plans to use the 8i database within the 9iAS machine as the place where the EJBs would be stored. There was a comment from the Oracle support people that the EJBs would be better off stored on the backend. We are trying to do the same.
We have experienced mainly two problems
1) While trying to deploy the container managed beans through JDeveloper, just after creating the deployment profile, an error ORA - 00904 comes up. (no columns). Then there is a prompt to install BC4J. On doing that the error comes up again and while it goes further, it says 'Exhausted ResultSet'. But the BMP entity beans are working OK.
2) We had a bug report from the Oracle people on entity bean support through JDeveloper on non-NT machines. But we have been trying to deploy beans on the Solaris DB using JDeveloper and we keep getting 'peer socket disconnected errors'. I'll try the workaround which was suggestesd by the Oracle people to solve the problem and get back on this.
I don't know how Oracle will measure up to the performance when EJBs are running. But the problems mentioned above would have to be solved first.
Can anyone help out?
Thanks in advance.
Aby Philip

I can't resist a comment here. Oracle folks seem to always recommend putting the EJBs in back-end database. How many real-world enterprise-scale applications (i.e., one's that would need EJBs at all) have a non-shared back-end database? And in those cases, who in their right mind would accept running application code in the back-end database? I guess Oracle just hasn't really bought in to the concept of multi-tiered applications. The whole reason for separating the business logic tier from the EIS tier is to insulate the EIS services from the demands of the business logic code.
So from that perspective, I would highly recommend running an 8.1.7 instance in your middle tier to house your EJBs. Then you can hook up to your EIS tier either with database links, or (for better performance) by caching data in the EJB database from the EIS tier.
As for your specific issues, I can't help with the first. On issue 2, I am installing the 8.1.7.1 patch set today and I'll let you know if it fixes the JDeveloper --> Solaris deployment problem.

Clustering read-only bean-managed entity ejbs

          I'm designing a data caching approach that relies on using read-only entity ejbs with bean-managed persistence. My design is based on the fact that WebLogic blocks on entity bean access by concurrent users for a given bean instance (unique primary key). I would like to keep only one entity bean instance active(timeoutSetting=0) for eacy primary key for all users to share. That way I only have to hit the database one time to initially populate data in the entity bean. I'm worried about this approach in a WebLogic clustered environment. From reading notes in this newsgroup and other doc, it appears that WebLogic might not use one instance of the entity bean (based upon unique primary key) in a clustered environment. Is that true (that being multiple users could get their own instance of the entity bean with the same primary key)?
          Thanks,
          Bryan


Typically, the read-write EJBs are on each WL server instance, so there is
          no remote invocation -- it is all done by reference.

Is it possible to connect indesign with database/OOD...

Hello fellow Indesign user,
Not sure if this question belongs here or in scripting...
I'm just a moderate user in ID CS4 and I got this daunting task to find/invest a way to use Indesign (our existing layout software) to create "brochures/instruction manuals" using databases or OOD. Meanings, use a template, add a code that corresponds to a similar code with pre-defined data-entity in a database/OOD, and automatically add the text/pictures from the database/OOD.
We are not talking about addresses or simple things like that, but brochures and instruction manuals in different languages with different or similar operation for each machine. Some instructions are the same and some are not. Get my drift?
We are using ID Cs4 in the company right now, not the smartest tool to use when producing 25 different brochures/technical manuals with different languages. Changing one content in one manual, meaning we have to change all 25 brochures/manuals.... manually...
Many of you may think -"why did you start ID in the first place". The answer: I don't know, I wasn't here then... It is not until now they discovered -"Oh, we need a new system… " and guess who got the task to evaluate it…
I need to know if it is possible and to what extent we can use ID with database or an OOD-system to retrieve data (mostly custom data with bulletin, font, size, pictures, etc).
Articles, links and other information would be very helpful….
Thanks!

What kind TM exist out there and is it possible to integrate it with ID? (I can probably check Wikipedia, but it feels correct to ask the right question to ask to the right person here. How does your firm manage multilingual contents in ID? You gotto have the same problem as I do, at least to some extent…
How is it even possible to have an automated system and still have that flexible design freedom in ID..? Many questions here…
To invest a complete new system is not an option anymore. I made some calculation and plenty of phone calls. The figures does not look good at all… it’s simply not worth the time and money. So what are the options, if we keep ID in the firm?
Well, I should have had lots of time to answer your questions this evening, but it turns out that we're both out of luck. I'll cover a few things quickly to give you some Google-fodder:
1) Okay, I won't suggest expensive commercial solutions.
2) Read up about how to flow XML content into and out of ID
2b) Store your content in the DB of your choice, spit out XML, and then update your INDDs with it.
3) Think about an open-source TM app like OmegaT
4) Do you do all of your translations in-house? If not, ask your suppliers how they work.
5) But really, if you don't have a completely obsessive person in charge of making sure everything is up to date, you're asking for trouble. I'm reminded of a quote by Edward Tufte who was talking about project management; I can't remember the quote, but the idea boiled down to the fact that you can do just as good a job with whiteboards as you can with databases. At least right now you know that you haven't kept all versions up to date... if you were housing all your content in a database, then the update process is somewhat hidden from you, and you wouldn't know if something broke unlesss you caught it in QA. If you're not doing all the updates... then you can't do good QA.This is a recipe for disaster.
5b) Establish a good workflow with whatever tools you have (database, whiteboards, little strings with knots tied in 'em, notches carved in the thighbones of extinct birds of prey, etc.) and give someone the power to sanction/punish/fire people who disobey workflow rules. I am not kidding.
I will make more useful suggestions (suggestions more useful than 5b, at any rate) in the near future.
