BMP - Do I need to have cmp-field element ..

Hi,
I am using the BMP and i wonder someone can help me to understand if I need to include the <cmp-field/> element in my ejb-jar.xml file.
Currently I am getting error when I do the build and it expects to see the <cmp-field/> tag in my ejb-jar.xml file.
I appreciate your help and time.
Cheers,
A

This is now resolved. for BMP, we dont need to have cmp-field fields in ejb-jar.xml

Need to add new fields to the condition table

Hello All,
The requirement is to create the new condtion table for MM containing the following fields and maintain the entries in this table:
- client
- characteristic
- class
- internal characteristic.
THe condition tables are created via tcode M/03 or through the customizing path
Material Management > Purchasing > Conditions > Define Price Determination Process > Maintain Condition Table.
The problem which i am facing is as follows :
-SAP has the standard procedure for the generation of the condition tables . Selected fields are made available by SAP in the field catalog and we can select only from the those available fields. Once we select the required fields the condition table is automatically generated in the background.
-As the requirement is, we need to have 4 fields in the generated condition table (client, characteristic, class and internal characteristic), but the problem is that none of these fields are available in the field catalog which is provided by SAP (in tcode M/03, M/04 and M/05).
-Designing of the Z table wonu2019t be useful as we would not be able to use the Z table as the condition table.
Can you please suggest how can we add the desired field to the existing field catalog in M/03 or is there any other alternate solution to this ?
Thanks in advance for your help.

Please post your code which you developped until now and show us where the problem is. I cant see any ABAP related question.

Cmp-field of type 'java.lang.Long' does not have a no-arg constructor

Hi,
I am a newer of Oracle9i JDeveloper and I am learning it by "Oracle9i JDeveloper Reviewers Guide". I did the sample as the guideline in "Oracle9i JDeveloper Reviewers Guide". But when I tried to run the sample I made, the error : "cmp-field of type 'java.lang.Long' does not have a no-arg constructor which is needed for properties/fields based mapping" was appeared.
Any one know how to correct it?
Thanks in advance.
Best Regards,

I'm getting the same thing. The message doesn't indicate which of the four beans I have that use type Long is encountering this. I suspect that since it says 'constructor' it is one of the two which uses an Long for a primary key.

Can I cause checking a box to add 1 to a calculated form field? I have a field that sums the numbers entered in several previous fields and need to be able to add "1" if a checkbox is selected as well.

Can I cause checking a box to add 1 to a calculated form field? I have a field that sums the numbers entered in several previous fields and need to be able to add "1" if a checkbox is selected as well.

I think it has something to do with the way the value of the check box is exported, but I'm not sure. With nothing being exported to Data5, Data6 displays the sum of Data1-4 rounded down to the nearest whole number and updates automatically as Data1-4 are updated.
Right now, assuming Data1-4 are 0, where data 5 is the output of the second example and any box is checked, "1" is displayed in data5 but nothing is added to data 6. Selecting any other check box or deselecting that check box will cause data6 to add 1 even if data5 displays "0". By way of example:
Selecting Check box 16 results in Data5 displays 1 and Data6 displays zero.
Then, if any or all of Checkbox17-20 are selected, Data5 displays 1 and Data6 displays 1.
Then, if any or all of Checkbox17-20 are deselected, Data5 Displays 1 and Data6 displays1.
Then, if Checkbox16 is deselected, Data5 displays 0 and Data6 displays 1.

All cmp-fields that double as cmr-fields must have an object type??

Greetings,
I'm deploying an application in weblogic 8.1sp2 that worked fine in
jboss 3.2. The error is:

this relationship has a primitive type. All cmp-fields that double as
cmr-fields must have an object type. . at
weblogic.ejb20.ejbc.EJBCompiler.doCompile(EJBCompiler.java:255) at
Does it means that I should cmp field from "int" type to "Integer"
object??? If true, I really don't know why the requirement since in
jboss worked just fine. But do you confirm it?

Pedro Salazar

I believe there is a requirement that any field used as a primary or
foreign key must be an object and implement hashCode/equals.
I'd post in weblogic.developer.interest.ejb.cmp if you want more
information.

What version of Reader are they using, exactly? And are you sure they're
using Reader itself and not opening the file inside a browser window, for
example?

Weird Problem with BLOB CMP field

Hi,
I am trying to deploy an EJB2.0 CMP Bean in Weblogic6.1 .The Bean has one of the CMP Field as a serializable object mapped to a BLOB Datatype in Oracle8i
When i try to creae this Entity Bean
I get "java.io.IOException: ORA-22920: row containing the LOB value is not locked" as a nested exception.
When i increased the isolation level . I got "java.io.IOException: ORA-01002 fetch out of sequence" as the nested exception
And one more horrible thing that is happening is the other arguments to the create method are getting updated in the DB except the Blob field(Supposed to rollback? when there is an EJB Exception ??)
Any thoughts? Comments?
Regards
Sathya

Hi,
I seem to recall that there are multiple issues with BLOBS & WLS. I'll describe my setup, and you can see if your missing anything:
- In weblogic-cmp-rdbms-jar.xml you need to set the column type as a Blob:
<field-map>
<cmp-field>binary</cmp-field>
<dbms-column>binary</dbms-column>
<dbms-column-type>OracleBlob</dbms-column-type>
</field-map>
- In weblogic-ejb-jar.xml you may need to set the isolation level of your set method:
<transaction-isolation>
<isolation-level>TRANSACTION_READ_COMMITTED_FOR_UPDATE</isolation-level>
<method>
<ejb-name>TerminalSoftwareKernelBDO</ejb-name>
<method-name>setBinary</method-name>
</method>
</transaction-isolation>
- The bean get/set methods should look like this:
public abstract void setBinary(java.lang.Object binary);
public abstract java.lang.Object getBinary();
- In WLS 6.1 up to Service Pack 2 (I don't know about SP3 yet), BLOBs are incorrectly implemented. For some (odd) reason you can only put serialized objects into the DB... I think this means that if you have a BLOB put in by anything but WLS, WLS get very unhappy. So empty out your table with the blobs first.
Hope that helps.
Daniel.

A cmr-field and a cmp-field on the bean are using the same name. The names

Hi:
I am using weblogic 8.1 and MyEclipse 5.1.1. I am deploying my ear application through MyEclipse 5.1.1 as an ear file.
When I ran the following EJB QL:
SELECT OBJECT(p) FROM Product p.category = ?1
I get the following error:
n relation Category-Product, a cmr-field and a cmp-field on the bean are using the same name. The names of cmr and cmp fields must be unique.
It is basically complaining that I have a field
<cmr-field>
                         <cmr-field-name>category</cmr-field-name>
                    </cmr-field>
in my ejb-jar.xml and also the same category in the
<cmp-field><field-name>category</field-name></cmp-field>
field. The problem is that if I changed the value of the cmr-field, I have to add a get and set in my productLocal.java and when you do that you have to do the same in the ejb-jar.xml.
Here is my ejb-jar.xml:

Hello,
I have two ejbs, one called EstablishmentEJB and another called VisitorCommentsEJB. The relationship is of one EstablishmentEJB instance to many VisitorCommentsEJB instances.
Here are the definitions for the tables:
CREATE TABLE establishments (
DB_ESTABLISHMENT_ID int(11) NOT NULL default '0',
DB_POSTCODE varchar(100) NOT NULL default '',
DB_ESTABLISHMENT_NAME varchar(255) NOT NULL default '',
PRIMARY KEY (DB_ESTABLISHMENT_ID)
) TYPE=InnoDB;
CREATE TABLE visitors_comments (
DB_VISITOR_COMMENT_ID int(11) NOT NULL auto_increment,
DB_ESTABLISHMENT_ID int(11) NOT NULL default '0',
DB_COMMENT varchar(255) NOT NULL default '',
PRIMARY KEY (DB_VISITOR_COMMENT_ID)
) TYPE=InnoDB;Here are the xml DDs:

Thanks all for replying,
The error occurs when I run the client and not at deploy time. Here is the client code:
     public void addComment(Integer primaryKey, String comment) {
          System.out.println("primaryKey------>" + primaryKey);
          try {
               PGEstablishmentLocalHome establishmentHome = (PGEstablishmentLocalHome) PGServiceLocator.getInstance().getLocalHome("PGEstablishmentHome_L");
               PGEstablishmentLocal establishmentLocal = establishmentHome.findByPrimaryKey(primaryKey);
               establishmentLocal.addComment(primaryKey,comment);
          } catch (PGServiceLocatorException e) {
               e.printStackTrace();
          } catch (FinderException e) {
               e.printStackTrace();
u haven't defined the PK entry in the Establishment EJB Bean in DDYes look in the standard DD.
What's more I need both DD as I would with most ejb containers.
The field DB_ESTABLISHMENT_ID is required and I cannot set it to NULL.
Any other help greatly appreciated.

How to add new CMP field to CMP bean

I am back for your amusement. I have seen similar things to this in other postings, but I have not been able to find one that, when action is taken, solves my problem.
I am using Sun Java Studio Enterprise 7 2004Q4
Our database changed by adding one new field. I need to update the bean for that table. Since the bean was created from a schema, I thought I need to update the schema first. Having found no way to do that yet, I recreated the schema under a different name, deleted the old one and renamed the new one to the old name. Follow that? :|
Ok. So now I have a new schema with the old name. I still have the old one in CVS so I can get it back (see I am learning someting).
I then went to the bean and added a new CMP field. I updated all my code to use the new field accessors. Changed the create method to have one more field and use the accessor.
Then in the module where the bean is being used I mapped the new field to the field in the database. The CMP is in a relationship with two other beans, but this field is not used (not yet anyway).
I then compiled and depoyed. Everything went ok. "I am really getting the hang of this EJB stuff", I said to my self. Then I tried to run it.... I should have saved the comment for another time... :(
I got this message and exception :
"Validation error in class com.PersonCMPBean685435892_JDOState: com.sun.jdo.api.persistence.model.util.ModelValidationException: Warning: Cannot find the column person.p_umd_id for mapping the field pUmdId in the class com.PersonCMPBean685435892_JDOState.
Verify that the schema file exists and that its contents are correct."
com.sun.jdo.api.persistence.support.JDOUserException: The mapping for class com.PersonCMPBean685435892_JDOState is invalid. Compile the class in the IDE, correct any errors, and verify that all required files are packaged for execution.
The schema exists. The field is in the new schema. Hmmm. I screwed up. Stamp it on my forehead with the others from working with EJB.... :)
So what did I do wrong? How is this supposed to be done. Is there an easier way to update the schema?
Any help will be greatly appreciated. Thank you.

Ok. I found something that works, albeit I don't think it is the recommended way. But since I can't find a recommended way, I will settle for working. This was a suggestion from someone else who had this problem ( http://swforum.sun.com/jive/thread.jspa?forumID=122&threadID=23428 ). But I have broken it down into steps and refined it a bit.
1. Create a new schema under a different name.
2. Go to the module that has a bean that is using the old schema.
3. Find the reference for the bean under the module and look at the properties for the bean.
4. In the properties in the Sun Java System As section there is a property called Mapped Schema. Change it to the new schema.
5. deploy
There's more...
If you need to have the same name for the schema, like I did because I keep it in CVS, do this:
6. Shutdown the IDE
7. Go to the directory where the schema is and rename it to whatever you need (whatever you had originally).
8. restart the IDE
9. repeat steps 2-4
10. restart the IDE again before you deploy!
I know this is insane. But it is all I could figure out so far. If anybody has something else that is better, please, please, please let me know!

Javax.ejb.EJBException: Method is not a known CMP field accessor...

Hi !
I have a little problem. When I deploy my jar file, I have the next message :
"javax.ejb.EJBException: Method is not a known CMP field accessor, CMR field accessor, or ejbSelect method: methodName=compareTo"
Is there someone to tell me why ? ^_^
I didn't put the source code in this topic, not to pollute it, but if you need it, tell me ;)
Thx for your help.

Hi Spidey !
Thx for you help but... Giving my method doesn't require the use of EJBQL, I don't think I have to define it in my deployment descriptor (this is not a query)...
I give you an idea of my (experimental ^_^) source code :
public class CountryBean implements EntityBean{
public int compareTo(Country c){
SOP("COMPARE TO");
return 0;
public class MySession implements SessionBean{
public int doIt(){
MyComparator comparator = new MyComparator();
return comparator.compare(country1, country2);
public class MyComparator implements Comparator{
public int compare(Object o1, Object o2){
return compare((Country)o1, (Country)o2);
public int compare(Country c1, Country c2){
SOP("COMPARE");
return c1.compareTo(c2);
When I call doIt(), the message "COMPARE" is written and just after, there's this message (the message "COMPARE TO" is never written):
"11:29:44,204 ERROR [LogInterceptor] TransactionRolledbackException, causedBy:
javax.ejb.EJBException: Method is not a known CMP field accessor, CMR field accessor, or ejbSelect method: methodName=compareTo

at org.jboss.proxy.compiler.Runtime.invoke(Runtime.java:59)
at CountryBean$Proxy.compareTo(<generated>)"
I hope this is clear ^__^
Thx for helping me ;)

Need to get 2 fields displaying on same line, but close together

hi -- I have 2 related fields that I want to display on the same line -- the first has length of 10, the second length of 20.
On the same page, I also have some fields that are length 100.
Let's call my first field ID and my second field NAME. I want NAME to display quite close to ID (maybe about 5 characters apart).
I have its Begin On New Line = NO in display attritutes, Field = YES, and col and row span = 1.
But the field of length 100 -- let's call it BIG -- causes problems. NAME displays way out to the right, beyond the end of BIG.
I've tried setting the column span on BIG to 3 or 4; it helps a bit, but not much.
I'm not sure how column widths on a page (if there is such a thing) are defined, but I'd like to get NAME displaying in the
column after ID (or close to it, whatever will help me do this), where the space between ID and NAME is maybe 5 or 10 characters.
How can I do this?
Thanks much,
carol

hi Denes -- I've looked extensively at your example, and I think I understand conceptually what needs to happen. But I'm not
quite getting yet. I've been playing around alot with the column span of the various items on my page... I'm wondering if you'd
take a look at something I posted on apex.oracle.com. (workspace dew_mir, user [email protected], pswd labitu). Application 30636
Field LOV Display, page 2.
Of the left fields, Site Name, Site Common Name and Description are col span of 3. Latitude, Longitude, Elevation, Date Time Loaded
and Date Format are col span of 2. The rest (the short ID fields) are 1.
Objecttype Name and Lat Name represent the fields I want displaying further to the left. I'd expect Objecttype Name to
be rendered after the end of the first column, which I would think would be just to the left of the short ID fields. Instead,
it looks like it starts after the 2 column fields. For Lat Name, I'd expect that to be rendered at the end of the second column,
which I'd think would be just to the left of the lat/long/elevation fields, but it's after the 3 column fields.
Clearly there's something I don't understand about how columns are set up.
Thanks,
Carol

I want to remove my credit card from my daughter's itunes account but i can't delete the information without getting a notification that i must have the fields filled out

I want to remove my credit card from my daughter's itunes account but i can't delete the information without getting a notification that i must have the fields filled out. When she first got the ipod touch, we did not need to supply credit card information for her to set up her account. Only now that I entered it for one purchase, I can't remove it. Now my daughter has purchased over $300 in downloads the last two weeks.

You definitely can.
To remove your payment information open iTunes and go into your account. An easy way to access your account is from quick links on the store home page. After you login there will be a payment type listed with an edit button next to it. Click edit then select none under card type (next to visa, mastercard, etc).
Afterwards at the bottom of the page select done, then your card will no longer be on file. It will prompt you for a card next time you try to download something that isn't free.

BMP - Do I need to have cmp-field element ..
