JBoss tools - Seam generate entities from existing entities

[mortena]

I've evaluated and tested the JBoss tools generate entities from existing entities and it turns out that the entities are overwritten by hbm2java instead of being used as they are. This undermines the usage of this tool to get a running seam application from a set of EJB3 entities:

* It removes all inheritance information in the entities
* It removes all documentation etc. in the entities

So:

* Why are the entities overwritten instead of being used as they are?
* Can this be configured so that the entities are used as they are?

In an iterative (real life) situation extra properties would be added to existing entities over time. If the Seam generate entities are run several times some information would be thrown away due to this procedure.

Max says this needs some (minor) changes to (hibernate) tooling to support (you could configure this on or off).

I guess you should take a look at the hibernate tools forum and jira, and submit a patch :)

[maxandersen]

btw. for seam-gen you could just comment out the hbm2java generation in there and not regenerate.

btw. morten - report it in jira; much higher chance for me to notice it ;)

it seems to me this question is related to JBSEAM-843

Hmm. I think that you should consider using fewer lines of communication.

There's an awful lot of tools involved. seam-gen, jboss-tools, eclipse, jira, this forum, hibernate tools forum, ...

:-)

How can I get the "Seam Generate Entities" function working in eclipse without regnerating the entities?

JBoss Tools -> JBoss Tools forum (easy, right ;)

"How can I get the "Seam Generate Entities" function working in eclipse without regnerating the entities?"

For now you can remove the hbm2java from the generated code generation launch and just rerun it.

For getting that more permantly in there report an issue in jboss tools.

It is *related* to JBSEAM-843 but we don't use the ant tasks in jboss tools so this is not the same.

Where should I remove it from (a build file?)

Go to Run > Hibernate code Generation and select the "yourproject-generate-entities" configuration.

go to exporters and remove the hbm2java/.java exporter.

btw. I created and fixed http://jira.jboss.com/jira/browse/JBIDE-1336 just for you ;)

There is no plan to create a "generate-ui" task?

For 1.2.1 there is "http://jira.jboss.org/jira/browse/JBSEAM-1206"

Removing hbm2java is not enough because the entities from db are still considered. No way to use my entitites?

Pete Muir just integreted JSEAM 843 (Generate application from existing entities) in CVS.

For 1.2.1 there is "http://jira.jboss.org/jira/browse/JBSEAM-1206"

This issue is related to "improve i18n in seam-gen". What is the link with this thread?

[pmuir]

See, we look at votes :)

marious - I talked about how to do it in jboss tools.

if you want to do it in ant files you need to swithc jdbc-configuration out with jpa-configuration.
