ejbc uses classloader.getResourceAsStream to find the ejb-jar.xml. Is it possible
that it's finding another copy of the file. I would change something in your
ejb-jar.xml (ie make it so the parser will fail.) and make sure that ejbc hits that
error.
If you're still having problems, can you post your ejb-jar.xml and
weblogic-ejb-jar.xml?

Error deploying entity bean on web logic server

i am trying to deploy a container managed persistence entity bean on web logic server when i run the command ejbc which generates the final jar file ready to deploy having its stub and skeleton it gives me the error that the return type of create(int) method should have a type of bean home interface while in accordance with ejb1.1 specicication it should be the type of primary key and a null value should be returned.
plz let me know where i am doing it wrong.

thanks for ur quick response sir i am using this services provided by sun microsystem first time and
am really thankful to Sun Microsystem for this great deal of help to the new commers but sir my problem is still there.
following is the method which i have written in the code
     public InvoicePK ejbCreate(int id)
          this.id=id;
          return null;
and here it is the error generated by the server deployment tool.
[9.2.8] In EJB Invoice, the return type for the create method create(int) must be the bean's remote interface type.
[9.2.8] In EJB Invoice, the findByPrimaryKey method must return the Entity bean's remote interface type.
[9.2.8] In EJB Invoice, the return type for the method findByPrimaryKey(com.swi.InvoicePK) must be the entity bean's remote interface type (for a single-object finder) or a collection thereof (for a mult-object finder).
the detail of files created by me are as follows.
1. Invoice (Entity Bean)
2. InvoicePK (Primary Key file)
3. MyRemoteInterface (remote interface for entity bean)
4. MyHomeInterface (home interface for entity bean)
plz let me know where i am doing wrong and oblige.

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!!
Isidro

getter 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!

If 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.

WLS 5.1.0 SP 12 ejbc throws NoSuchMethodError on entity beans

Greetings all,
Due to a trashed hard disk, I'm in the middle of getting WebLogic
server reinstalled. Because of some problems with Oracle 8.1.6 and
WLS 5.1.0 SP9, I've been trying to get SP12 to run, with little luck.
I suspect an installation / configuration problem, but I don't know
what it is.
The symptom is that I can't compile entity beans - ejbc throws a
NoSuchMethodError exception. For the sake of simplicity, and to prove
to myself it wasn't our code, I tried building one of the examples,
and it has the same problem. Does anyone see anything I've done
wrong in the configuration?
Below is the captured output from build & wlconfig:

Do all the examples fail to build, or just the EJB CMP examples? I ask
because in 5.1, there's a separate WebLogic_CMP_RDBMS.jar that's part of
the install process, but it's only used for CMP. If the other examples
work, then that's likely to be your problem.

Error While Deploying A CMP Entity Bean With A Composite Primary Key

Hello all,
I have a problem deploying CMP Entity beans with composite primary keys. I have a CMP Entity Bean, which contains a composite primary key composed of two local stubs. If you know more about this please respond to my post on the EJB forum (subject: CMP Bean Local Stub as a Field of a Primary Key Class).
In the mean time, can you please tell me what following error message means and how to resolve it? From what I understand it might be a problem with Sun ONE AS 7, but I would like to make sure it's not me doing something wrong.
[05/Jan/2005:12:49:03] WARNING ( 1896):      Validation error in bean CustomerSubscription: The type of non-static field customer of the key class
test.subscription.CustomerSubscriptionCMP_1530383317_JDOState$Oid must be primitive or must implement java.io.Serializable.
     Update the type of the key class field.
     Warning: All primary key columns in primary table CustomerSubscription of the bean corresponding to the generated class test.subscription.CustomerSubscriptionCMP_1530383317_JDOState must be mapped to key fields.
     Map the following primary key columns to key fields: CustomerSubscription.CustomerEmail,CustomerSubscription.SubscriptionType. If you already have fields mapped to these columns, verify that they are key fields.Is it enough that a primary key class be serializable or all fields have to implement Serializable or be a primitive?
Please let me know if you need more information to answer my question.
Thanks.
Nikola

Hi Nikola,
There are several problems with your CMP bean.
1. Fields of a Primary Key Class must be a subset of CMP fields, so yes, they must be either a primitive or a Serializable type.
2. Sun Application Server does not support Primary Key fields of an arbitrary Serializable type (i.e. those that will be stored
as BLOB in the database), but only primitives, Java wrappers, String, and Date/Time types.
Do you try to use stubs instead of relationships or for some other reason?
If it's the former - look at the CMR fields.
If it's the latter, I suggest to store these fields as regular CMP fields and use some other value as the PK. If you prefer that
the CMP container generates the PK values, use the Unknown
PrimaryKey feature.
Regards,
-marina

Please tell me what's the problem ?
with regards

i found what's the problem i made the url for lookup as the following:
lookup("java:comp/env/Book_catalog")
instead of
lookup("ejb/Book_catalog")
could anyone tell me what's the difference between 'java:comp/env/' and without it
by the way i used for lookup Datasource the following and it's working
DataSource dataSource = (DataSource)jndiContext.lookup("jdbc/TECHBOOK");
thanks

Error while deploying Entity Beans on OC4J 10.1.3

Hi,
We have 350 entity beans in our system. Recently a new table is created as per following script.

Entity Bean for the same has been created. While deploying I am facing the following error.

Hi,
The error was coming because of the table structure. All the columns were composite keys. I alter the structured by removing composite keys and added a new column as primary key. Now it is getting deployed successfully.
Can anybody comment on such a behaviour of OC4J?
Regards,
Jinal Shah

Deploying CMP entity bean throws compilation error.

Jdeveloper build works fine but the server deployment ( embedded) fails. I linked tools.jar to j2ee home dir, same version as jdev uses. Session beans deploy OK.
The table corr to the entity bean has a primary key and the entity bean was created by dragging-dropping table onto UML diagram.
error is >>>cmp-field of type 'java.lang.Long' does not have a no-arg constructor which is needed for properties/fields based mapping<<<, message details follow after dashed line.

Error Deploying CMP Entity Bean

Hi,
I am new to Entity Beans and am trying to deploy a CMP Entity Bean without any success.
I did search this forum for similar issues and tried those suggestions as well but that has not helped. Was wondering if someone could help me out on this.
The Entity bean has 2 fields: name and description.
The ejb-jar.xml file for this bean is:
<enterprise-beans>
<entity>
<ejb-name>Product</ejb-name>
<home>example.cmp.ProductHome</home>
<remote>example.cmp.Product</remote>
<ejb-class>example.cmp.ProductBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
<reentrant>false</reentrant>
<cmp-version>2.x</cmp-version>
<abstract-schema-name>PRODUCTS</abstract-schema-name>
<cmp-field>
<field-name>name</field-name>
</cmp-field>
<cmp-field>
<field-name>description</field-name>
</cmp-field>
<primkey-field>name</primkey-field>
<query>
</query>
</entity>
</enterprise-beans>
The error that I get while deploying the bean is:

Bad Performance/OutOfMemory Error in CMP Entity Bean with Large DB

Hello:
I have an CMP Entity deployed on WLS 7.0
The entity bean maps to a table that has 97,480 records.
It has a finder: findAll() -- SELECT OBJECT(e) FROM Equipment e
I have a JSP client that invokes the findALL()
The performance is very poor ~ 150 seconds just to perform the findAll() - (Benchmark
from within the JSP code)
If more than one simultaneous call is made then I get outOfMemory Error.
WLS is started with max memory of 512MB
EJB is deployed with <max-beans-in-cache>100000</max-beans-in-cache>
(without max-beans-in-cache directive the performance is worse)
Is there any documentation available to help us in deploying CMP Entity Beans
with very large number of records (instances) ?
Any help is greatly appreciated.
Regards
Rajan

Hi
You should use a Select Method, it does support cursors.
Or a Home Select Method combination.

Yes, the problem is that the ejb-jar must contain at least one ejb component. It's a common misconception that Java Persistence API Entity classes are ejb components but they are NOT. The Java Persistence API was developed within the EJB 3.0 JSR and works very well with EJB but the entity classes themselves are not full-fledged ejb components.
