I have spent some time investigating this, and have some of the answers.
I took the deployment descriptors that were in Rickard's
deployed classes directory, and stripped them down to the bits relevant
to a single CMP entity (Account, with its ejb reference removed).
I then used EJX to generate new deployment descriptors (ejb-jar.xml,
jboss.xml, jaws.xml) from scratch, trying to match the stripped-down
targets. I got close - there are a couple of issues left that will need
someone else's help. (Look for ***** markers below)
Here's the process, step by step:
1. Create an ejb-jar for an Account bean with CMP
Start EJX, click on New, select EJB1.1 XML
Expand the EJBJar tree node, select Enterprise beans.
In the right-hand pane, click Add entity bean, and in the resulting
dialog give it the EJB name: Account.
Expand the Enterprise Beans tree node, select Account.
Fill in the details:
Display name: Account
Remote interface: org.ejboss.test.bank.interfaces.Account
Home interface: org.ejboss.test.bank.interfaces.AccountHome
Bean class: org.ejboss.test.bank.interfaces.AccountBeanCMP
Primary key field: id
Primary key class: java.lang.String
Persistence type: Container managed
Reentrant: Reentrant
Click Add CMP field and give the name: id
Click Add CMP field and give the name: balance
Click Add CMP field and give the name: owner
In the CMP tab, type in descriptions for these fields:
Account Id
Account balance
Account owner name
Save as ejb-jar (this matches Rickard's content perfectly)
2. Create a jboss.xml deployment descriptor for the Account bean
In EJX, click on Open, use Files of type: jBoss XML, and open
the ejb-jar.xml you just saved.
Expand the jboss and Deployed beans tree nodes, and select Account.
In the Entity tab, enter
JNDI name: bank/Account
Container configuration: CMP EntityBean
(you can copy and paste this from the CMP EntityBean container
configuration)
Look at the CMP Entity Bean container configuration. Ensure you have the
right JRMP container invoker for your JDK version.
Set Persistence manager: JAWS O/R CMP
If you want the smallest possible XML file, delete the container
configurations you are not using. (Right button on the tree node and
select Remove.)
Save (no prompt for a file name - it saves as jboss.xml in the directory
you found the ejb-jar.xml in).
***** The resulting jboss.xml file matches the target
***** except for one minor difference - it has
***** <secure>true</secure> where Rickard has
***** <secure>false</secure>.
3. Create a jaws.xml CMP deployment descriptor for the Account bean
In EJX, click on Open, use Files of type: JAWS XML, and open
the ejb-jar.xml again.
Expand JAWS configuration tree node, select Deployed beans.
In the Enterprise beans tab, enter
Data source: Hypersonic
Type mapping: Hypersonic SQL
[BUG: mappings are not displayed properly]
Select Account tree node.
In the Entity tab, enter
Table name: Account
Create on deploy: checked
Remove on un-deploy: not checked
Tuned updates: not checked
In the CMP mappings tab, fill in the blank fields as follows:
Description Column name SQL type Field name
----------- ----------- -------- ----------
Account owner name owner ejb/Customer owner
Account id id VARCHAR(256) id
Account balance balance REAL balance
Finding by primary key is already looked after: you only have
to add finders that do queries on content. Rickard has one that
looks for accounts with balances greater than a given parameter.
In the Entity tab, click Add finder
In the Finders tab, enter:
Finder name Order Query
----------- ----- -----
findLargeAccounts balance balance > {0}
If you want to keep your XML file size to a minimum, delete the type
mappings for the databases you are not using (Right button on the tree
node and select Remove.)
Save (no prompt for a file name - saves as jaws.xml in the directory you
found the ejb-jar.xml in).
***** THIS DOES NOT POPULATE THE <jdbc-type> ELEMENTS IN THE jaws.xml.
Rickard's jaws.xml had VARCHAR for the id, REAL for the balance, and REF
for the owner.
So close...
