Problems deploying entity beans with local interfaces on Jboss?

I'm trying to deploy a simple entity bean using local interfaces on Jboss 3.2.1 and I obtain the following exception:
19:08:51,875 WARN [verifier] EJB spec violation:
Bean : UsersEJB
Section: 9.2.2
Warning: The entity bean class must not be defined as abstract.
19:08:51,875 WARN [verifier] EJB spec violation:

Section: 9.4.7.1
Warning: The primkey-field element must name a public field in the bean implemen

Any idea?
Thanks,

I guess you are missing <cmp-version>2.x</cmp-version> for your first warning and <primkey-field>primary key field </primkey-field> for you second warning in your ejb-jar.xml

Deploying entity beans with Local interfaces on Jboss

Hi, I'm trying to deploying a simple entity bean on Jboss. The EJB has been developed with Local Interfaces because then I want to access it with a session bean facade.
I get the following error:

23:41:25,984 WARN [verifier] EJB spec violation:

I'm following what is wrote in the Professional EJB editeb by wrox?
Is it possible to deploy an entity bean alone with Local interfaces? Is there something I'm missing? It's true that I defined the implementation class as abstract, but because there are abstract getter/setter methods.
Thanks for any help,

Do I need to Create Primary Key Class for Entity beans with Local interface

Do I need to Create Primary Key Class for Entity beans with Local interface?
I have created my entity bean with the wizard in Sun One Studio and it does not create a primary key class for you.
I thought that the primary key class was required. My key is made up of only one field.
Anyone know the answer.
Jim

u dont need to create a primary key class for a entity bean.if ur table's primary key feild(int ,float) is a built in or primitive data type,then u dont need one.But if ur table has a primary key field which is non primitive (for example StudentID,ItemID etc)then u have to create a primary key class.
hope this helps :-)

CMP Entity beans using local interfaces

Why CMP entity beans with CMR relation ship using local interfaces only?
Why we should not use remote interface to get the CMR field relationship?
Pls give me the solutions

"Local interfaces provide the foundation for container-managed relationships among entity beans and session beans. The bean uses the local interface to maintain its references to other beans. For example, an entity bean uses its local interfaces to maintain relationships to other entity beans. Using local interfaces, beans can also expose their state and use pass-by-reference to pass their state between related bean instances. "

Problem with Local Interfaces (WSAD 5)

I built an Entity Bean with Local Interface and a Remote Interface (apperently they both have the same JNDI name in WSAD)
and when I look up for the name from other Session Bean (same EJB group) and I try to cast it to the local interface there is a classCastException.............
HELP ME

Nidhi
I had the same problems as you that went away. If you have both remote and local interfaces defined, and your remote inerface can be accessed via JNDI lookup using (say) "ejb/sessionbean/stateless/HelloHome", then you can access the local intercafe using "local:ejb/ejb/sessionbean/stateless/HelloHome".
The URL http://localhost:9080/UTC/initialize?port=2809 is very useful to browse the JNDI tree. Just expand "Local EJB beans" and position your mouse over the item of interest. The JNDI lookup name will echo in the bottom (solid) frame of the browser. The only problem is that the jndilookup name will appear (mistakenly) as local:/ejb/ejb/stateless......, just get rid of the first forward-slash to make it look like local:ejb/ejb/stateless....
Hope this helps

CMP Entity Bean with ejb-ql finder methods and INFORMIX database

Hi,
I have some CMP Entity Beans with finder methods defined in ejb-ql. In my ejb-jar, within <entity> definitions I have something like:
    <entity>
      <abstract-schema-name>BeanName</abstract-schema-name>
      <cmp-field><field-name>fieldOne</field-name></cmp-field>
      <cmp-field><field-name>fieldTwo</field-name></cmp-field>
      <query>
        <query-method>
          <method-name>findAll</method-name>
          <method-params></method-params>
        </query-method>
        <ejb-ql>SELECT OBJECT(o) FROM BeanName o</ejb-ql>
      </query>
    <entity>
And in persistent.xml:
<db-properties>
     <data-source-name>datasource_name</data-source-name>
</db-properties>
<entity-bean>
     <ejb-name>BeanName</ejb-name>
     <table-name>table_name</table-name>
     <field-map key-type="NoKey">
     <field-name>fieldOne</field-name>
     <column><column-name>column_one</column-name></column>
      </field-map>
     <field-map key-type="NoKey">
     <field-name>fieldTwo</field-name>
     <column><column-name>column_two</column-name></column>
      </field-map>
      <finder-descriptor>
          <method-name>findAll</method-name>
          <method-params/>
     </finder-descriptor>
Once deployed, on server side, I can found a java source file (with corresponding compiled class file) in path:
j2ee/cluster/server0/apps/companyName/MyEARApp/EJBContainer/temp/temp38837373733/route/to/package/
with names:
BeanName0_0pm.java
BeanName0_0PM.class
and the generated java file contains this code:
public java.util.Enumeration ejbFindAll() throws javax.ejb.FinderException, javax.ejb.EJBException {
    TransactionContext tc = pm.getTransactionContext();
    Connection conn = null;
    PreparedStatement pSt = null;
    ResultSet ejb_rs = null;
    int status = javax.transaction.xa.XAResource.TMSUCCESS;
    try {
      conn = pm.getConnectionForFindMethod();
      pSt = conn.prepareStatement("SELECT \"O\".\"COLUMN_ONE\",\"O\".\"COLUMN_TWO\", FROM \"TABLE_NAME\" \"O\"");
      ejb_rs = pSt.executeQuery();
I'm trying to call this method but it throws a SQLException when preparing the statement.
It seems that Informix does not like this SQL syntax because of upper case names, doble quotes on table alias, or something else.
When editing persistent.xml in netweaver, I can define the element <datasource-vendor> as ORACLE, SAPDB, MS_SQL_SERVER, DB2_UDB_AS400 or DB2_UDB_OS390 but INFORMIX is not an accepted value.
Is there any way to define how this SQL query is build?
Thanks in advance.

The return type of the finder method defined in the remote home interface is either the entity bean's remote interface or a collection of objects implementing the entity bean's remote interface. The return type of the finder method defined in the local home interface is either the entity bean's local interface or a collection of objects implementing the entity bean's local interface

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.

Deploying EJB with Local Interfaces.

HI everybody
I am trying example on EJB with LocalInterfaces with BMP.
My bean without Local interface is deployed and working fine.
Then i have changed Home & Remote interface code. Again i have deployed it . It is deployed but i am unable to Look Up.
I am using J2SDKEE1.3 server & JDK1.3.
I have changed both interface files as follow:-
I have made my Home interface as :
public interface RetrieveConditionHome extends javax.ejb.EJBLocalHome {
     public RetrieveCondition create(String SQL_WHERE_ID, String SQL_WHERE_NAME,
          String FROM_TABLE , String WHERE_CLAUSE , String LAST_UPD_USER_ID ,
          Date LAST_UPD_TMSTMP, int ROW_VERSION)
          throws CreateException;
I have made my Remote interface as :
public interface RetrieveCondition extends javax.ejb.EJBLocalObject {
     public String getSQLWHERENAME() ;
-Viren

In JMS tutorial : They have stated ejbCreateLocal method.
I am not using this method in my Bean class. I am using general ejbCreate method as we normally do .
I am really confused about these methods : ejbCreate & ejbCreateLocal.

Deployment error in 9.0.3 for app with local interface

While attempting to port an EJB-application from jboss to oracle, I have encountered a deployment error in 9.0.3 9iASR2 which I cannot decipher. The same ear-file is successfully deployed on the 9.0.3. OC4J standalone version (both on a machine running winXP)
I get a "syntax error in source" when I attempt the deployment and all my local-interface class-files end up on the j2ee_home root, i.e. <oracle-home>/j2ee/home/.
Am I too early using local interface on version 9.0.3, is my packaging messed up or should I look for my bugs in some missed logfile?
BTW: where do I find deployment stack traces for this version of 9iAS?
Dag

Hi,
you can find deployment stack traces in the following location \ORACLE\806\opmn\logs. i think this might help u.
I am also facing a problem like com.evermind.compiler.CompilationException: Syntax error in source,did u know cause for this.
Thanks and Regards,

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

Error While deploying Entity Bean

Hi,
We are using JDeveloper 3.2.2 to deploy EJB into Oracle 9ias (Oracle 8.1.7 database). The following error occured while deploying entity bean.
"Persistence provider declared in the deployment descriptor is not supported
*** Errors occurred while deploying the EJB to 8i JVM ***
*** Deployment completed ***"
Please help us with the solution if anyone have come across this kind of error.

Thank you Raghu, We were in a position to deploy the entity bean to the database. We solved the problem by adding the following parameters to the init.ora file
(a) Java_max_sessionspace_size
(b) java_soft_sessionspace_limit
When I tried to create an EJB for a table in another schema, it started deploying the BC4J to that schama also. Is it necessary that BC4J should deploy in all the schemas of the database ? Can I deploy BC4J to one schema and grant required permissions to others users or create public synonym for BC4J ? Can you please tell me how I can deploy BC4J globally for an instance of Oracle (Applicable to all the schemas in that instance) ?

Is it possible to map the cmp fields of the entity bean with out dictionary

Dear sirs,
I have created the EJB project module and WEB Module. Now i have to map the CMP fields of the entity bean to the underlying table. Is it possible to map the cmp fields of the entity bean with out java dictionary? If yes how can we do that.
I have got some error while mapping an EJB's CMP fields to the table through dictionary. I was actually intended to map 79 fields but it gives an error that more than 64 fields are not allowed while building the dictionary.
1. Can you tell me what could be the possible reason?
2. Is it possible to map the cmp fields of the entity bean with out java dictionary? If yes how can we do that.
Kindly helo me,
Sudheesh K S

Hi,
Sudheesh please check up if the below link helps,there are other ways of writing the persistent.xml for container managed entity bean.
http://help.sap.com/saphelp_nw04s/helpdata/en/9b/f695f0c84acf46a4e0b31f69d8a9b7/frameset.htm, probably in the studio you cannot browse through tables not in the java dictionary,but manually editing it may still solve the problem.
Also here is another link that specifies the databases supported by J2EE Engine.
http://help.sap.com/saphelp_nw04s/helpdata/en/66/a5283eeb47b40be10000000a114084/frameset.htm
The below link shows how to specify the database vendor and datasource

Creating entity beans with auto numbered primary key

I have two entity bean with a CMR between them. I am successfully creating the first one but when I try and create the child entity bean I get a NullPointerException.
Now I think this is because the gernerated code tries to get the primary key of the created entity bean and this is not set as it is set using a auto number in the database (An oracle sequence and trigger).
Is there anyway i can get round this problem?
Thanks in advance,
Adrian

This is the auto generated code:
     public dmd.sync.ejbs.entity.AppliancePackInfoLocal create_Local(dmd.sync.dataobjects.dto.AppliancePackInfoDTO appliancePackInfoDTO, dmd.sync.ejbs.entity.AmppLocal amppLocal) throws javax.ejb.CreateException, java.rmi.RemoteException {
          BeanO beanO = null;
          dmd.sync.ejbs.entity.AppliancePackInfoLocal result = null;
          boolean createFailed = false;
          boolean preCreateFlag = false;
          try {
               beanO = super.createBeanO();
               dmd.sync.ejbs.entity.AppliancePackInfoBean bean = (dmd.sync.ejbs.entity.AppliancePackInfoBean) beanO.getEnterpriseBean();
               preCreateFlag = super.preEjbCreate(beanO);
               bean.ejbCreate(appliancePackInfoDTO, amppLocal);
               Object ejsKey = keyFromBean(bean);
               result = (dmd.sync.ejbs.entity.AppliancePackInfoLocal) super.postCreate_Local(beanO, ejsKey, true);
               bean.ejbPostCreate(appliancePackInfoDTO, amppLocal);
               super.afterPostCreate(beanO, ejsKey);
It must be falling over on the last line as it calls the ejbPostCreate fine.

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.

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