BI Beans with MOLAP

Hi,
I want to do a crosstab based on a cube of my Analytic Workspace.
But I don't want to do have a ROLAP cube built with a relational view of my AW.
Is there a another solution ?
Thanks
Yann

there are a few options:
1) Yann can create the necessary ADTs, RDBMS Views, and CWM2 metadata in order to make his AW usable by the OLAP implementation of the DataSource provided by the BI Beans;
2) When AW Manager is released on top of 9.2.0.4, Yann can create his AW cube in "Standard Form", and then use the DBMS_AWM package to enable the AW cube for use by the OLAP API and the BI Beans;
3) Yann can implement his own data source -- as long as his data source implementation implements the DataDirector and DataAccess interfaces, then he can get a crosstab up and running.

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.

Multiple users accessing entity bean with same PK

Hi,
Some body please clarify the below issue.
(EJB 1.1, WAS3.5)
I have two app servers and two clones each clone is running in each app server.
Stateful session bean access Entity beans to update/read record in the database.
According to my requirement multiple users can access the same entity data (same primary key). Suppose user A created a Stateful session bean SB1 and the SB1 created Entity1 with PK1, this is happening at clone1.
User B accessed the site and the request went to Clone2 and a new SB2 created, but the SB2 need to access the database with Same PK1.
For the above situation, I guess container can not create a new Entity bean with PK1 because EB with PK1 is already there and it tries to allocate same EB1 with SB2, so if two requests are concurrent do the SB2 wait to get the handle of the EB1?
Is there any way to create two Entity beans with same Primary Key at the same time but in different clone?
Thanks,
Sagar

Hi,
The concurrency level has to be set at the level of database and the database will take care of consistency & integrity of the data. So specity the concurrency level on the database connection in each appserver.

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
http://help.sap.com/saphelp_nw04s/helpdata/en/e1/67fc3ee241ba28e10000000a114084/frameset.htm
Hope you are able to solve the problem.
Do let us know if you come up with the solution.

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.

Entity bean with primary key generated by trigger

Hi,
We have a table(oracle) with one column as primary key,
but the primary key is generated by trigger every time
a new row is inserted into this table, inside the trigger,
it uses oracle sequence to get the next val.
If we want to use entity bean with it, what should we specify, it's not application-managed primay key, it's
not auto-generated primary key either. How can we resolve
it without change the database part.
Any thought is appreciated.
Thanks
afang

The code is already there with JDBC call inserting
into the table, the inserting trigger then will generate
sequence key and being inserted into primary key column.
Now wondering if it's possible to change the code to use entity bean but without modifying the trigger (since it contains other business logics).

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.

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

Hi Gaurav,
Other applications used the same the datasource, which I used for this application,
are running fine.
I think there is some bug in the wlserver 6.1 to create the join table. I think
it is the time I should ask the bea wlserver 6.1.

Killing a bean with application scope?

Is there any way to kill a bean with application scope?
I am writing a web application, that most likely the browser window will never be closed. The problem is a user is authenticated onto our site but because the bean containing the users acct info is application scope, if another user logs in it still shows the old user as logged in. So on logout i would like to kill the application, the bean, servletContext...anything that will refresh the bean and the corresponding jsp. Any help is much appreciated.

There is an indirect way if you know servlets. The "application" implicit object that you use in your JSP is the javax.servlet.ServletContext object. Instead of declaring your bean using the jsp:useBean tag, directly put your objects into the ServletContext using ServletContext.putAttribute() method. Objects put in the ServletCOntext are available to all pages in the application. Just use the ServletContext.getAttribute() method to retrieve this bean in any other page.
To "kill the bean", just reset the value of this object to null by calling putAttribute(null).

Calling a Bean with parameters

I would like to be able to call a JSF managed bean with a call such as
How can I code to use a href directly to call a faces managed bean method without using listener?
Thanks in advance.

Take a look at: http://blog.exadel.com/?p=19

Passing a form bean with a link

Hii Javaties
I am passing some parameters from a jsp page to the action class in the following manner
�2=<bean write name="formbean" property="prop2" />Link
Can anyone tell me is this the right approach to pass paramters from a link .
Can i pass the whole form bean with a link ?

From what I understand you are using Struts, and as much as I know you have to configure struts so that when you click for example on a link with the url set as hello.do, it will actually get the hello form bean and handle it. However as much as I know you have to do this from the xml configuration!
I am not expert in struts however, but that is my feeling.

Share stateful session bean in JSF managed beans with different scope

Hi,
I have a JSF application and I want to try to use of stateful session beans.
So I created a new stateful session bean and its local interface.
@Stateful
public class StatefulSessionBean implements StatefulSessionBeanLocalInterface{
private String name;
@Local
public interface StatefulSessionBeanLocalInterface {
...In my JSF application I have a mananed bean with session context which registers the new interface by
this annotation
@EJB(name="sessionbeanref", beanInterface=StatefulSessionBeanLocalInterface.class) and set the name to something.
Now I want to fetch this name in another managed bean with request scope. So I looked up the bean and tried to get the name.
StatefulSessionBeanLocalInterface = (StatefulSessionBeanLocalInterface) new InitialContext().lookup("java:comp/env/sessionbeanref");
System.out.println(currentmailingbean.getName());but the name is null.
Why?

The xsd was created via the netbeans J2EE enterprise application dialog and I think its the most recent.
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">All other annotations seem to work.
Wouldnt the lookup completely fail if the deployment process thought that it is version 1.4 ?

Using java bean with jsp

hello friends,
i'm new to jsp. i want to create an html form that accepts username and a value from four radio buttons and display back the entered name and checked radio button's value using java bean.
i use the <jsp:setProperty id="" property="*"> method. i don't know how to access the radio buttons value from the html.
also when i use an additional field other than username the jsp page is showing error.
Please give me the correct method to use java bean with jsp in this circumstance.
thank you.

thank you, but i have a problem left. the case is like this.
i got the jsp and bean worked fine when i have a sinle input text field.
but when i added a second text field i recieved the following error.
javax.servlet.ServletException: basket.newbean.getUserPass()Ljava/lang/String;
     org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:825)

     org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
where userPass is the new form element. I have made the subsequent chanes in my bean program and jsp file.
pls hlp.

set PRE_CLASSPATH=%BEA_HOME%\modules\javax.persistence_1.1.0.0_2-0.jar;
%BEA_HOME%\modules\com.oracle.jpa2support_1.0.0.0_2-1.jarApplication which works on WLS 10.3.6 is http://download.oracle.com/otn/nt/middleware/11g/wls/1036/wls1036_dev.zip and the one which is not working is
http://download.oracle.com/otn/nt/middleware/11g/wls/1036/wls1036_win32.exe.
How can I resolve these errors and exceptions? Any help is highly appreciable.
Thanks

Looks like you might have a spelling error in your spring config, or are trying to set a read-only property. BdasInterfaceManagerImpl has been configured as having a method called setBdasInterfaceJdbcDao() : does it?
By the way, we now know that you're writing code for JP Morgan - there's a slight risk that this could bite you in the @ss at some point (there are some malicious people around) you might want to take that into consideration next time!
