Re: [castor-dev] Castor behaves differently within JBoss

[Keith Chew]

 

I don't know. According to a previous post by Thomas, he mentioned that it's fixed in CVS. But from your desciption, it is indeed working as a standalone (Thomas is correct), but fails in Jboss.

 

Tell me if you figure this one out. I need the key generator too, just waiting for a fix.

Indeed, removing "Sequence" key-generator from the referred object seems to alleviate this problem. But why?

Thanks, Keith. It is a great workaround for now, but I can't live without the key generation long-term....My DB admin will kill me ;-)

Can you do a quick change to disable key generation on Company?
 
I recall having this problem, but it is supposed to be fixed in CVS. However, I have already disabled key generation for my class.
 
Just try that. It's worth a go.

Referring object (Test) does not use key generation, but referred object (Company) does use SEQUENCE.

I have had similar problems. Quick question. Are you using the key generator for your referenced object?

Subject: [castor-dev] Castor behaves differently within JBoss

Hi,

I have just established that Castor, if used within JBoss, will not persist references to other objects.

The same code/mapping will work just fine stand-alone.

For example if we have an object of class Test reference an object of type Company, that reference will not be saved to the DB table if run in JBoss.

I suspect that I may have something misconfigured. However, dependencies (not references) are persisted correctly.

What do I need to do here? Any JBoss-Castor exeperts?

Oleg Nitz, are you there?

Thanks in advance,

Environment:

JBoss 2.4.3, Oracle 8.7.1 All transactions are bean-managed, set to "RequiresNew"

This DOES NOT SAVE the reference to Company (JBOSS Session Bean)

This is a session bean (remote) method:

public Test createTest(Company c)

    throws InvalidArgumentException, ReflexServerException, RemoteException

    {

        Company co = null;

        Test t = null;

        if (c == null)

            throw new InvalidArgumentException("Argument cannot be null");

        try {           

            co = (Company) pm.findByPrimaryKey(test.Company.class, new Integer(30));

            t = new Test(70);

            t.setOwnerCompany(co);

            System.out.println("Co " + co);

            System.out.println("test " + t);           

            pm.create(t);

        }

        catch (Exception ex) {

            if (ex instanceof InvalidArgumentException)

               throw new InvalidArgumentException(ex.getMessage());

            else {

                ex.printStackTrace();

                throw new ReflexServerException(ex.getMessage());

            }

        }

        return t;

    }

This WORKS:

public void test() {

        Company co = null;

        Test t = null;

        Database db;

        try {

            db = jdo.getDatabase();

            db.setAutoStore(true);

            db.begin();

            writer.println("Begin transaction");

            co = (Company) db.load(test.Company.class, new Integer(30));

            t = new Test(70);

            t.setOwnerCompany(co);

            System.out.println("Co " + co);

            System.out.println("test " + t);

            db.create(t);

            db.commit();

        }

        catch (Exception ex) {

            ex.printStackTrace();

            System.out.println("Exception " + ex);

        }

    }

Mapping:

<class name="test.Company" identity="companyID"  key-generator="SEQUENCE">

        <cache-type type="count-limited" capacity="200"/>

        <description>Company</description>

        <map-to table="Companies"/>

        <field name="companyID" type="integer">

            <sql name="companyID" type="numeric"/>

        </field>

        <field name="companyCode" type="string">

            <sql name="code" type="varchar"/>

        </field>

        <field name="tests" type="test.Test" collection="arraylist">

            <sql many-key="ownerCompanyID" />

        </field>

    </class>

    <class name="test.Test" identity="testID">

        <cache-type type="count-limited" capacity="200"/>

        <map-to table="Tests"/>

        <field name="testID" type="long">

            <sql name="testID" type="numeric"/>

        </field>

        <field name="ownerCompany" type="test.Company">

            <sql name="ownerCompanyID"/>

        </field>

     </class>
