3-tier, client synchronization, JavaGroups

Hi,

we try to run Cayenne(3.0m6) in 3-tier mode with client synchronization.

We set up a configuration to use cross-vm caching through JavaGroups (2.2.1)
(with standard configuration).
We have a simple object with a string attribute (ItemCategory, name).
We have a tomcat5.5 deployed with the default HessianServlet (Hessian
version: 3.1.6).
We have a client that connects to the server, like
        String myChatRoom = "1111";
        ClientConnection connection = new HessianConnection(
                "http://192.168.3.154:8081/HVS_CAYENNE_V3/HVS_DATA", "hvs",
"hvs",
                myChatRoom);
        DataChannel channel = new ClientChannel(connection);
        context = new CayenneContext(channel, true, true);

then the client fetches an object
        SelectQuery select = new SelectQuery(ItemCategory.class);
        category = (ItemCategory)
context.performQuery(select).iterator().next();

we have a simple gui, which can update the name property:
        category.setName(nameField.getText());
        context.commitChanges();
the server accepts the requests, changes the database and logs also the
following message:
2009-08-04 14:03:29,125 DEBUG http-8081-Processor23
org.apache.cayenne.access.DataRowStore - postSnapshotsChangeEvent:

Maven 2 Modeler - dependences problem

Hi, I'm back!
Hope this time I can stick with cayenne and contribute as well.

Hi Gilberto!

Don't know where Objectstyle repo had gone, but now everything seems to
build OK. Looking forward for your contributions! :)

Maven 2 Modeler - Configuration

Hi,

I need more information about this plugin. Until now, this [1] is only
source I've could find.

Can I setup my database on pom.xml file? For example:
[code]
			<plugin>
				<groupId>org.apache.cayenne.plugins</groupId>
				<artifactId>maven-cayenne-modeler-plugin</artifactId>
				<version>${cm.version}</version>
				<configuration>
					<driver>${jdbc.driverClassName}</driver>
					<username>${jdbc.username}</username>
					<password>${jdbc.password}</password>
					<url>${jdbc.url}</url>
					<src>src/test/resources/cayenne.xml</src>
				</configuration>
				<dependencies>
					<dependency>
						<groupId>${jdbc.groupId}</groupId>
						<artifactId>${jdbc.artifactId}</artifactId>
						<version>${jdbc.version}</version>
					</dependency>
				</dependencies>
			</plugin>
		</plugins>
[/code]

How can I set it to:
* open the cayenne.xml from the project it is running;
* use maven classpath

Re: Maven 2 Modeler - dependences problem

I must have misunderstood you first. There is certainly a problem with
launching modeler plugin. Adding Objectstyle repo to my pom helped for me:

<repositories>
<repository>
            <id>objectstyle</id>
            <name>Objectstyle Repository</name>
            <url>http://objectstyle.org/maven2</url>
            <layout>default</layout>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
            <releases>
                <enabled>true</enabled>
            </releases>
        </repository>
    </repositories>

Please do so until the problem is fixed.
Also shapshots seem to be not updated, so Modeler3.0M5 (not M6) is starting.

Cayenne POJO inheritance

Hi, sometime ago I've tried cayenne JPA [1] and that time I couldn't
touch POJO source code.
Now this is a personal learning and I want do the cayenne way.

So trying Andrus advices:

1 reverse engineer the DB in question with CayenneModeler
2 manually tweak the model to match the property names in the existing
POJO Java classes
3 Run class generator to generate the _Xyz superclasses.
4 Change the existing classes by hand to inherit from _Xyz counterpart.
5 Remove existing persistence fields, and use superclass getters and
setters to access them. * Change the API throughout the code to use
Cayenne ObjectContext and Queries.

I've stopped on 4 when I saw the source generated
(osu-park/src/main/resources/codigo). The class inheritance looks a
little odd.

While testing my original code I do this
(osu-park/src/test/java/park/model/party/PessoaTest.java):
[code]
public class PessoaTest {

	 <at> Test
	public final void testPessoaFisica() {
		Pessoa p;
		p = new PessoaFisica(1, "Gilberto", "F", "Endereço",
Date.valueOf("2009-01-01"), "RG", "CPF");
		assertNotNull(p);
	}

	 <at> Test
	public final void testPessoaJuridica() {
		Pessoa p;
		p = new PessoaJuridica(1, "Souza e cia", "J", "Endereço",
Date.valueOf("2009-01-01"), "CNPJ");
		assertNotNull(p);
	}
}
[/code]

How would it be with the new generated code? I think I need a good reference!

Thanks,

Example of getting data from non-JDBC datasource?

Does anyone have an example of how to get data from a non-JDBC data 
source, or some docs/instructions/etc. of how this can be done?

Re: Example of getting data from non-JDBC datasource?

No non-jdbc examples that I know of, but I'd say you needed to create
your own implementation of Interface DbAdapter.

http://cayenne.apache.org/doc/api/org/apache/cayenne/dba/DbAdapter.html

You could use the JdbcAdaptor as an example:
