CMP JOINQUERY - URGENT

hi,
Is it possible to write a join query in CMP. from multiple tables to retrive the data using find by method.
if no please give me reason. if yes how can we write.
thanks in advance

I mean to say u don't write any queries in CMP. Use BMP instead for such a requirement.

One reason that I sometimes get 'NoSuchMethodError' is when I make a change to a
java class that is imported into another java class. When I go to run the
importing class, it will throw a 'NoSuchMethodError' on any methods that I've
changed in the imported class. The solution is to recompile the importing class
with the changed classes in the classpath.

URGENT HELP ON BMP CMP!!!

Hi everybody!!
I've wrote few CMP EJB's before and now Im trying to write a BMP EJB.
In the finder methods I�ve to select data from two tables:
"product_catalog" and "product" (relation One to many)
The query that matches my needs is:
SELECT DISTINCT a.product_code, b.product_description
FROM product a, product_catalog b
WHERE a.product_code = b.product_code
AND (a.region_code = '00' OR a.region_code = 'variable argument')
AND b.product_line <> '08'
Note that in the FROM clause of the query data is retrieved from two tables and that the WHERE conditions involve both tables.
�A query like this can be implemented into a finder method of a BMP EJB?
�What about the descriptor? -Im using Websphere Application Server 4.0-
�How can I tell the container which fields will be persistent?
�Which fields should I've to specify as primary key fields? �The ones from the parent table? �What about the ones from the child table? �What about the query in the ejbLod() and the ejbStore() methods that select and update data from the table(s)?
I've looked at the J2EE tutorial examples but none of the examples uses a query like mine.
As you can see I need URGENT help on this.
All the help you can give will be greatfully welcome!!
THANKS!!!

Greetings,
Note that in the FROM clause of the query data is
retrieved from two tables and that the WHERE
conditions involve both tables.IOW: an "inner join"...
�A query like this can be implemented into a finder
method of a BMP EJB?BMP differs from CMP in that as the bean coder: you are in control of the query and therefore can be as simple or as complex as required without required to the container's query language support. However, remember the implementation rules of finder methods:
1. A finder method's purpose is simply to locate entities in the resource; and, therefore...
2. A finder method returns an instance of the PrimaryKey class (or collection thereof).
Also...
a. The container calls a corresponding ejbFind method on an instance in the free pool; and, therefore...
b. A finder method should not attempt to manipulate bean state.
Therefore, as long as the data returned by your join query (a.product_code, b.product_description), compose a PrimaryKey class instance, you are fine.
However, I will add that it should be remembered that an EBs purpose is to provide an OO representation of shareable, persistent, data ("entities") in an enterprise resource. They have a specific purpose and do not merely provide "data access" or act as "resource managers". From your example given, it seems your "entity" may be uniquely identified from 'a.product_code', a common primary(?) key in both tables and that the code is actually trying to act as a report writer. If your SELECTed data (a.product_code, b.product_description) do not together comprise a unique entity representation in your application then this is incorrect usage. In this case you should either generate the query from a Session Bean or create separate Entity Beans for each of your tables 'a' and 'b' and handle your 'joins' in business methods.
�What about the descriptor? -Im using Websphere
Application Server 4.0-Your descriptor will identify the bean's <persistence-type> as "Bean". This is all it needs to know about the bean since the Bean is Manag[ing] it's own Persistence (BMP ;).
�How can I tell the container which fields will be
persistent?Er, you don't. BMP beans manage their own persistence and, therefore, manage their own fields. Refer again to the above.
�Which fields should I've to specify as primary key
fields? �The ones from the parent table? �What about
the ones from the child table? �What about the query
in the ejbLod() and the ejbStore() methods that select
and update data from the table(s)?These are all questions related to how your application requires an "OO representation of its resource data" to be mapped to the backend resource(s). Only "you" can really answer these questions. However, refer back to the above for some implicit pointers. :)
I've looked at the J2EE tutorial examples but none of
the examples uses a query like mine.The tutorial is intended for beginners to J2EE development and, therefore, provide only simplistic examples. For a more thorough examination, refer to the J2EE Blueprints.
As you can see I need URGENT help on this.
All the help you can give will be greatfully
welcome!!I hope this helps.
THANKS!!!

Please help me it is urgent, if i could understand it i can proceed further

Hi,
I had the same error as you. I'm agree with arvind_India (previous). You must :
1. Define a correct Connection Pool (warning: deploy it on your managed server).
2. Test your connection Pool on your managed server.
3. Create a DataSource from your connection Pool.
4. Deploy your DataSource on your managed server.
5. Verify the JNDI TREE of your managed server (Now, the JNDI name of your dataSource must appair).
6. Deploy your Entity Bean (the error has disapeared).

Urgent: Can't lookup entity bean

Dear all,
I define a business process in workflow engine, which invoke a java class to get
DB data through CMP entity bean. The entity bean was packed in to a ear and was
workable/callable within the same ear.
However, when the workflow engine can't invoke the entity bean, the workflow engine
always throw exception as following.
javax.naming.LinkException: . Root exception is javax.naming.NameNotFoundException:
Unable to resolve 'app/ejb/ConsignmentEntityBean.jar#Consignments/local-home'
Resolved: 'app/ejb' Unresolved:'ConsignmentEntityBean.jar#Consignments' ; remaining
name 'ConsignmentEntityBean.jar#Consignments/local-home'
I think the problem may occur in deployment/configuration. Since the problem is
very urgent, anyone can help me? To all developers, How do you package/deploy
Entity Bean in Integration Server?
Thx,
Philip

I solved this.
Since I was testing the action code only, I didn't define a navigation entry corresponding to the action string returned for this button:
<h:commandButton value="Add" style="height:21px; width:51px;font-size:8pt; font-color: black;" action="#{resourceBean.addAction}">
</h:commandButton>After I added a nav definition, it worked. I don't know why at this point. I suspect a key step in the lifecycle was pre-empted...someone else can probably explain why. If I get a chance to research it after I'm done with my project, I'll update this post.
Thanks.

How to upload a BLOB file from CMP Entity Beans

Hi,
I want to upload a .xls file as a BLOB using CMP. And also to get back the BLOB from the database through CMP. I am using oracle 8i DataBase and weblogic 8.1 server with weblogic workshop as IDE.
I don't have any idea to save a file as BLOB.
Could any one please help me to solve this as it is very urgent.
regards
KumudaRajarshi

I would just put the .xls file into a byte array in a
class that implements the serializable
interface. This class then becomes a column in your
database table(as a blob) represented by an
attribute in your entity bean. On sun appserver7
serializable is mapped to a blob column in the
database by default. You don't have to deal with a
blob at all in the code, just your
serializable type. You may have to use a type 2
driver to get it to work with files
over 4 or 5k.
See the appserver7 EJBdevguide, page 92 for details.could you descrbe the detail how to use the class to become the column as blob?
is that any sample code can be provided?
it's very urgent, please help..
thanks

Hi Ashutosh Gulkhobre,
I coppied the dump from the ST22.
Now please tell me solution fro this error ?
Runtime Errors OBJECTS_OBJREF_NOT_ASSIGNED_NO
Exception CX_SY_REF_IS_INITIAL
Date and Time 27.06.2007 09:54:55
 Short text
 Access via 'NULL' object reference not possible.
 What happened?
 Error in the ABAP Application Program
 The current ABAP program "SAPLHRXSS_PER_MAC" had to be terminated because it
 has
 come across a statement that unfortunately cannot be executed.
 What can you do?
 Note down which actions and inputs caused the error.
 To process the problem further, contact you SAP system
 administrator.
 Using Transaction ST22 for ABAP Dump Analysis, you can look
 at and manage termination messages, and you can also
 keep them for a long time.
 Error analysis
 An exception occurred that is explained in detail below.
 The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
 caught in
 procedure "HRXSS_PER_CLEANUP" "(FUNCTION)", nor was it propagated by a RAISING
 clause.
 Since the caller of the procedure could not have anticipated that the
 exception would occur, the current program is terminated.
 The reason for the exception is:
 You attempted to use a 'NULL' object reference (points to 'nothing')
 access a component.
 An object reference must point to an object (an instance of a class)
 before it can be used to access components.
 Either the reference was never set or it was set to 'NULL' using the
 CLEAR statement.
 How to correct the error
 Probably the only way to eliminate the error is to correct the program.
 If the error occures in a non-modified SAP program, you may be able to
 find an interim solution in an SAP Note.
 If you have access to SAP Notes, carry out a search with the following
 keywords:
 "OBJECTS_OBJREF_NOT_ASSIGNED_NO" "CX_SY_REF_IS_INITIAL"
 "SAPLHRXSS_PER_MAC" or "LHRXSS_PER_MACU04"
 "HRXSS_PER_CLEANUP"
 If you cannot solve the problem yourself and want to send an error
 notification to SAP, include the following information:
 1. The description of the current problem (short dump)
 To save the description, choose "System->List->Save->Local File
 (Unconverted)".
 2. Corresponding system log
 Display the system log by calling transaction SM21.
 Restrict the time interval to 10 minutes before and five minutes
 after the short dump. Then choose "System->List->Save->Local File
 (Unconverted)".
 3. If the problem occurs in a problem of your own or a modified SAP
 program: The source code of the program
 In the editor, choose "Utilities->More
 Utilities->Upload/Download->Download".
 4. Details about the conditions under which the error occurred or which
 actions and input led to the error.
 The exception must either be prevented, caught within proedure
 "HRXSS_PER_CLEANUP" "(FUNCTION)", or its possible occurrence must be declared
 in the
 RAISING clause of the procedure.
 To prevent the exception, note the following:

 The main program was "SAPMSSY1 ".
 In the source code you have the termination point in line 13
 of the (Include) program "LHRXSS_PER_MACU04".
 The termination is caused because exception "CX_SY_REF_IS_INITIAL" occurred in
 procedure "HRXSS_PER_CLEANUP" "(FUNCTION)", but it was neither handled locally
 nor declared
 in the RAISING clause of its signature.
 The procedure is in program "SAPLHRXSS_PER_MAC "; its source code begins in

Creation of CMP bean for a Composite Primary key????

Hi
i am having a composite primary keys in one of my table in the database.
I am trying to create a new entity bean for this table but i don't know how to create one in case when there is a composite primary key for a table.
Can anybody let me know is it possible to do it.
what is the procedure to be followed for the creation of the Entity bean in case of a composite primary key.
I am using MySql as the database .Creating CMP type of Entity bean.
Any help in this regard will be greatly useful to me as this is very urgent.
Thanks & Regards
Vikram K

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.

Please help urgently.... strange error

Hello Everyone,
I have done a project which comprises of CMP Entity bean, stateless Session Bean. I have tested the project on inprise App server, it works fine. I use DB2 database. I have successfully installed the project on WAS4.0 Advanced edition. But my problem is that when I try to run the client program I get the Non-application exception -------
CNTR0019E: Non-application exception occurred while processing method create:
com.ibm.websphere.cpi.CPIException: COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0204N "BAIJU.CHILDREF" is an undefined name. SQLSTATE=42704; nested exception is:

----- Begin backtrace for detailCOM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT]
SQL0204N "BAIJU.CHILDREF" is an undefined name. SQLSTATE=42704
In the above error message "BAIJU.CHILDREF" is not actual table name (actual table name
on which i have created the entity bean is "BAIJU.CHILD_REF").I have noticed that Websphere by default removes any underscore ("_") from the table name or the Column name of the table (I have checked this in Schema.dbxmi & Map.mapxmi files). I have many tables names & column names which has underscore character in it. Every tables which has
underscores ("_") gives almost similar error.
The tables which doesn't have underscore ("_") in there name & which contains the column names without underscore ("_") works fine.
Does this means that Application deployed on WAs 4.0 should not have underscores ("_")
as the table & column name ??????
please help me urgently......
regards..
Ashish.

Are you using the DB2 JDBC driver, by default db2 will treat _ as wildcards for table names, you have to disable the wildcard property or else rename your table.
You can do this by using the client configuration assistant and disabling the wildcard property or by editting the db2cli.ini file directly.
Ensure that you have registered the database as an cli/odbc datasource so that the properties can be set, when u do this an entry will be created in the db2cli.ini file which is located in the c:\sqllib folder, edit the entry for the datasource and add the following line
UNDERSCORE=0

Dear JDC member;
I recommend to try to add local interfaces...They are optionnal, but they can make things work.
Also, the other issue with CMP you have to map correctly the fields to your tables.

If DB Column java.sql.Types=CHAR = Workshop autogen EJB CMP Filed=Boolean

Hi everybody 
When a user automatically
creates/generates an Entity Bean via BEA Workshop EJB Project option: â€˜new
Entity bean from database tableâ€™ and DB Table Column is of type CHAR,
Workshop creates a @ejbgen:cmp-field of Java type Boolean, NOT of
Character!
I completely agree that the developer
must be acquainted with the Data Base and DB Tables as well and he can manually
correct SET & GET
Boolean to Character in EJB source code view or heâ€™ll receive an error if he
tries to setFieldName(String/Character) in ejb
methods.
But suppose that a developer has
urgently received an order to build an EJB Project for a thousand of DB Tables
and he hasnâ€™t been acquainted with all of them. He has created the EJBs via 
â€˜new -> Entity bean from database tableâ€™. He has created some EJB Finders,
for example a finder:Â ejbgen:finder Collection findAll().
(Suppose he hasnâ€™t used group-name finder property)
He has invoked findAll()
method and depends on the JDBC Driver used, he will receive an 
ERROR,
printed within the Server start console at least OR the result after 
getFieldName() will be 'false', not an expected char
symbol.
Anxious conclusion: 
If Â DB Column Â java.sql.Types
= CHAR Â Â Â thenÂ Â
getJavaObjectType = BooleanÂ then corresponding
EJB CMP FiledÂ will always be Â Â BooleanÂ in BEA Workshop !
Following description considers the
PROBLEM:
Class
weblogic.jdbc.utils.schema.Column from weblogic.jar and its method
String getJavaType() has a switch(getType()) with case:
Â if(this.getSize() == 1) 
Â Â Â return "boolean"; 
else 
Â Â Â return "String";
and 

another Â method String getJavaObjectType() 
{
String s = this.getJavaType();
...
Â Â Â Â
if(s.equals("boolean")) 
Â Â Â Â Â Â Â return "Boolean";
Â Â Â Â
if(s.equals("char")) 
Â Â Â Â Â Â Â return "Character";
... } 
but according to switch(getType()) which
has NOTÂ a 'case' return char, 
'Character' will never be returned, so:
@ejbgen:cmp-field of Java type 
Character will never be generated by Workshop.
More often than not Â Iâ€™ve
ran into this little but disturbing problem, so Iâ€™ve corrected 
weblogic.jdbc.utils.schema.Column.getJavaType switch case as:
â€¦
Â Â Â Â Â Â Â
case 1: Â Â Â Â // '\001'Â //CHAR

Â Â Â Â Â Â Â Â Â Â Â if(this.getSize() == 1)
Â Â Â Â Â Â Â Â Â Â
Â Â Â Â Â return "char";Â 
â€¦
private
static final boolean 
CHAR_TO_BOOLEAN = false;Â Â Â Â //as
a field variable
â€¦
Â 
Using this
correction and precompiled class Iâ€™ve built and tested a lot of projects w/o
problems so far.
Best regards: George Moykin
P.S. I appologize to site Admins for posting the same topic in EJB forum, but it refers to EJBs too.

Hi, 
In your database, we have some columns of CHAR type and this is the decision of our DB architects. I understand the case â€˜maleâ€™ or â€˜femaleâ€™, true or false, either; but only if I must choose between 2 variants. Our DB columns contain char symbols such as â€˜:â€™, â€˜;â€™,â€™-â€™ etc. and for some inner purposes our architects decided DB columns to be of type CHAR, not VARCHAR. In this case, the Workshop transformation â€˜CHAR to BOOLEANâ€™ doesnâ€™t do useful work. So, Iâ€™ve decided to modify some weblogic.jar classes (as described) and now Iâ€™m able to generate Entity EJB from DBMS Tables w/o manual intervention. 
Best Regards

Re: Using CMP Entity Beans in Business Logic

One thing that you need to answer here is
"In the queries for the subsequent tables, in the where clause will the fields be the same and is it that only their values change?"
In the above is true I'd suggest going for a CMP as you save a lot of coding and transaction management out there.
If the above is not true and even the fields in the where clause change on fly there is no way that you can go for CMP. You will have to go for BMP.
Hope this helps decide

Hi.
You might try posting this message to the weblogic.developer.interest.cmp
newsgroup.

Hi,
I have made a few CMP entity beans which are mapped to single tables in
Oracle 8i.
Create and remove of a row is working fine via the entity bean.
But when i try to update a particular row it is not happening.
The steps that I am doing are :
1. call home.findByPrimaryKey(instance of the Primary key class)
2. remote.setXXX for the field to be modified.
when i invoke setXXX() method the methods are called in the following
sequence : ejbLoad() > setXXX() > ejbStore()
but the data is not getting persisted in the Data base ....in the column it
is still the same old data.
is it something to do with a commit call or some configuration issue??....
Is there any other step to be called
I am using Weblogic 6.1 Sp2
Any help will be appreciated....This is really urgent...

URGENT HELP ON BMP EJB!!!

Hi everybody!!
I've wrote few CMP EJB's before and now Im trying to write a BMP EJB.
In the finder methods I�ve to select data from two tables:
"product_catalog" and "product" (relation One to many)
The query that matches my needs is:
SELECT DISTINCT a.product_code, b.product_description
FROM product a, product_catalog b
WHERE a.product_code = b.product_code
AND (a.region_code = '00' OR a.region_code = 'variable argument')
AND b.product_line <> '08'
Note that in the FROM clause of the query data is retrieved from two tables and that the WHERE conditions involve both tables.
�A query like this can be implemented into a finder method of a BMP EJB?
�What about the descriptor? -Im using Websphere Application Server 4.0-
�How can I tell the container which fields will be persistent?
�Which fields should I've to specify as primary key fields? �The ones from the parent table? �What about the ones from the child table? �What about the query in the ejbLod() and the ejbStore() methods that select and update data from the table(s)?
I've looked at the J2EE tutorial examples but none of the examples uses a query like mine.
As you can see I need URGENT help on this.
All the help you can give will be greatfully welcome!!
THANKS!!!

Cmr filed . urgent help me

hello
I want CMR-FIELD to be the part of compound primary key class. How can i do this
b/c compound primary key class only takes CMP-FIELD. please help, it is very
much urgent.........
i am using in j2ee with ejb2.0
thanx
sai

You should just specify the field as cmp-field as usual then add the field in the cmr-field tag in the relationships portion of the deployment descriptor. There should be no problem with identifying relationships where the primary key is also a foreign key to another entity.
