Adding CMP-fields to a EJB in sun ONE studio 5

I have a CMP EJB, and initialized its fields against a table in a database (PointBase). When I later try adding additional fields, these fields naturally doesnt exist in the database.
Then i make a test-module for the CMP EJB. When I try mapping the CMP-fields, I get in trouble with the field that doesnt exist in the database-table.
How can I get around this problem, must I really manually update the database schema, or can I somehow "tell" SUN ONE studio to make the field for me.

yes, but is there a way of letting J2EE handle all
this "Under the hood", so i dont even have to worry
about the internal datastructure in the database?You could drop the table from the database and then have Studio or deploytool create the tables (now with the additional fields) on deployment.

Hep, we have the same problem. I am still trying to figure out why. I have some idea about the reason but I am testing my founding. It seems to me that the problem shows up when I add my database driver in Runtime/Databases/drivers tree (IBM DB2 driver: db2jcc.jar)
Like I am saying I am still checking the connection. When I am convinced that indeed that is the problem, I will then try to find out why and what to do to make my life easier.

Oracle.jdbc.driver.OracleDriver not found in Sun ONE Studio

I get this message when I try to connect to the database while creating an EJB. I have tried adding the path to my CLASSPATH, and to adding it to the various CLASSPATHs within Sun ONE Studio. IDE_HOME is defined correctly but OracleDriver.class is still not found. Anyone know what my problem might be?
Thanks,
Michael A. Moran

Hi Sujatha,
Thanks for responding. My CLASSPATH is as follows:
madonna% echo $CLASSPATH
/export/oracle/jdbc/lib:/export/oracle/jlib:/export/oracle/jsp/lib:/export/oracle/sqlj/lib/runtime.zip:/export/oracle/oem_webstage:/export/oracle/lib/aurora_client.jar:/export/oracle/jdbc/lib/classes12.zip:/export/oracle/sqlj/lib/translator.zip:/export/oracle/sqlj/lib/runtime12.jar:/export/oracle/lib/vbjorb.jar:/export/oracle/lib/vbjapp.jar:/export/oracle/lib/mts.jar:/export/oracle/javavm/lib/aurora.zip:/export/oracle/javavm/utl/ejb/lib/vbj30ssl.jar:/export/oracle/jlib/javax-ssl-1_2.jar:/export/oracle/jlib/jssl-1_2.jar:/export/oracle/lib/servlet.jar:/export/oracle/lib/http_client.jar:/export/oracle/lib/http_server.jar:/export/oracle/oem_webstage/oracle/jdbc/OracleDriver.class:/export/oracle:/export/oracle/jdbc/lib/nls_charset12.jar
Which as you can see includes classes12.zip and /export/oracle/oem_webstage/oracle/jdbc/OracleDriver.class
I have also set all the IDE internal classpath variables to the same settings. It has no effect. I still get the same message.

Trouble with mapping CMR field using Sun One Studio

I am having trouble adding a cmr between 2 entity beans. It is a simple one to one relationship, navigatable in only one direction. In the database I have a foreign key defined between the two tables that store the data for the beans.
I add the relation by selecting the 2 beans and define it as one directional, one to one , with the name "bb". I then map the relationship field via the properties/As Sun One tab. I use the foreign key defined in the database. All seems to be well.
Using Sun One AppServer 7 and Studio 4
Upon deploying the application I receive:
CMP Mapping Error in bean Sites:: Warning: The field bb is not mapped.
Set the column mapping for the field.

The CMR/CMP mappings is very instable.
Sunone Studio 5 has a lot of bugs when mapping CMP/CMR but i never saw this one, try to upgrade.
Please vote for this bug. It's killing me!!!!!!!!!!!!!!!

Build a EJB/ Application with Sun One Studio and deploy to Weblogic

Dear all,
My boss require me to use Sun One Studio 4 update 1 to do the development, but
I find it's a nightmare to deploy the EJB/ application to the WebLogic 6.1.
I've already installed the weblogic plug-in in the Sun One Studio.
During deploying I could not find any setting that ask me for the weblogic-ejb-jar.xml.
So I think the deployment will fail.
Is there any others tutorial or e-book that can help me to familiar with the deployment
process?
Many Thanks for all of you.

where do you get the weblogic plugin from ?
i am intrested in doing the same thing

Sun ONE Studio 4 Update 1 does not allow to deploy a module

I have created CMP entity beans based on a database schema captured using the jdbcodbc driver.Each one with its primary key and correctly validate.
Then I have created a module and added to the module all CMP beans. Then when I attempt to deploy the module I got the following error: Conents are not valid for Sun ONE Application Server and in the log: Validation failed for EntityBeans.XConnectTableBean. Verify that all fields are mapped.
The I went to the SUN ONE AS entity properties within the module. I changed the defualt value of Mapped Schema to the correct schema, but when I tryed to change the Mapped Primary Table to the correct table the OK button was grayed out with the following status message: Table CTPTable does not have a primary key. This is of course not true.
Did I something wrong or this is a bug on Sun ONE Studio 4 Update 1?
Is there any work around?
Thanks in Advance

Yes,
It was a known bug and fixed with the newer realeses. Try to use the capture schema utility of the appserver (Install directory>/bin/capture-schema).

Using JMF API with Sun One Studio v4 update 1 (community ed.)

Having great difficulty trying to utilise the JMF API I've just downloaded with Sun One Studio v4, update 1 (community edition).
After installing the API, I tried copying the the .jar files under the lib folder of JMF to the lib folder of sun one studio.
Although admittedly a novice in the field of adding API's I have attempted to add the .jar files into the libary of recognised modules but made no progress.
The problem is that although JMF API is installed, Sun One Studio does not seem to be aware of this and so does not recognise any associated libraries e.g. java.media or JMFApplet.
I would appreciate advice from anyone who knows how to configure Sun One Studio to utilise the JMF API.
Mark

All right, I think I may have solved it. After mounting jmf.jar I needed to update the parser database. All the libraries seem to be there.
Can someone clarify though, the trial program i'm using makes reference to: java.media
I don't have this module. I do instead have javax.media which I believe includes all the methods of the java version. Am I right or am I missing this crucial module??

Connecting to MySQL from Sun One Studio

Hi,
I am trying to connect to the MySQL from the Sun One Studio 5. I followed these steps.
1. I downloaded the MySQL software and installed on my local computer, it was successful.
2. I got the drivers [b][b][b]mysql-connector-java-3.0.8-stable-bin.jar and placed it in the <stdudio5>/lib/ext/ directory.
3. And I successfully got through that one also, and in the database section it showed me the icon for connecting to mysql database. I gave the url, username, and password. It worked fine.
4. Then I created the connection pool, JDBC resource, and Persistence manager for my server instance. It was also successful.
5. When I built a cmp bean accessing the table in mySQL database, it is giving me these errors.
If you notice these error, it is asking for vendor type. But i don't have any option to choose the vendor type when i configured the database resources.
Can soem body suggest some other method and clear this error. I am struggling with this since a week.
Thank you.

The AS7 error suggests that you have not set up the server startup classpath to include the driver jar. The steps to do this are included in the article mentioned in Chris's reply, namely:

Sun One studio

where to find the sun-cmp-mapping.xml in the Sun One studio enterprise 6.. I get the following error while validating:
CMP Mapping Error in bean empEntity:: The field deptid has an invalid fetch group. Default is not a valid fetch group for managed fields. If your field is not a managed field, it may be treated as one if you have a CMR to this bean which is mapped to the same column as deptid.
Select a different fetch group.
I need to change the fetch group for this field, but to no avail.. Please help..

You need to download the J3D separately, I installed in order:
J2SE1.4.2, then Sun ONE Studio 4, then J3D1.3, and wrote code in java3d with forte, and everything compiled quite nicely without having to do any tweaking.

Another bug in sun one studio?

is this another bug in sun one studio or something else.
i have set the author to a different name through
tools -> options -> java sources
but when i create session beans or cmp beans, it uses the previous name.
however java main classes display the new name

This looks like a bug to me. I didn't see anything in the bug database that was similar, so I would suggest that you file a bug at:

NetBeans With J2EE versus Sun One Studio Enterprise

What is the difference between NetBeans with J2EE and Sun One Studio Enterprise?
Which of the two would be more appropriate to use for creating GUI applications? Which one would be more appropriate for an EJB based web application?

Sun One Studio is Netbeans with additional "enterprise" functionality. As thing now stand, S1S is 1-2 releases behind NB, due to the time required to add the additional functionality. The added stuff is useful for large systems, and Sun supports S1S - but not NB.
Depending on your specific requirements, either one might do the job.
Both are now free, and it appears that they will stay that way.
And both can use Application Server and Tomcat (or JBoss, etc in the the case of NB 5), and both work with J2EE.

Setup MySQL datasource for Sun ONE Studio

Hello all,
I've tried to post this message on the Sun ONE studio forum, however, there were compilation errors with JSP pages. As I needed the answer urgently, I decided to get some help here.
I've successfully made connection to MySQL database during the CMP development. However, when I tried to run it, it said the JNDI Datasource can't be blank and provide username & password if necessary. I went back and gave it a name as jdbc/MySQL, and also provided the username & password. I then reran the app, and I got the following error
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.RemoteException: Unable to get JDBC DataSource for CMP ....
I've mounted the mysql.jar and hacked some other things to no success. Please help.
Thanks & regards,

Sun ONE Studio 4 CE (Can't seem to edit)

I can't seem to edit a certain segment of code. More specifically, the initComponents method. Please refer to the picture.
http://www.sugarworldinc/JavaOne_question.gif
I also right clicked the node, and there doesn't seem to be any option to make it editable. What am I trying to do? I'm trying to take out one of the fields in jTable1.
Thank you for your time.

Correct!
Well, since the source files (.java) are ASCII (text), I went in and edited the text via notepad. After saving the file, I opened up Sun One Studio and it actually reverted the code back to it's original state (the auto-generated text).
