Seam 2.0.1.GA and hot-deploy

gjeudy Mar 23, 2009 10:26 PM
Hi guys,
I have an exploded WAR and i'm trying the hotdeploy feature. Since seam components can only be deployed when copied under WEB-INF/dev and since classes in that folder cannot be seen by other classloader I decided to put all Seam components (no entities) including JSF validators and JSF converters in that folder.
When I regression test the application validator components are causing problems. No exceptions thrown when rendering the page initially but then I get the following exception on postback:

This only happens when hot-deployment is enabled.
Does hot-deploy support seam components that are also JSF converters or JSF validators ?
1. Re: Seam 2.0.1.GA and hot-deploy

gjeudy Mar 24, 2009 2:39 PM (in response to gjeudy)
Ok I discovered by trial and error that you cannot hot-deploy Seam JSF Converter or validator because JSF classes (loaded by WAR classloader) cannot see hot-deployed converters/validators. The below code snippet in StateHolder class throws a ClassNotFoundException:

// else the object to save did implement StateHolder try { toRestoreClass = loadClass(className, this); } catch (ClassNotFoundException e) { throw new IllegalStateException(e.getMessage()); }

Can any Seam developers comment on the exact eligibility of Seam components for hot-deployment? To me it seems like only vanilla Seam POJOs are eligible and moreover they must not be referenced by classes outside the hotdeploy folder...

Yes, only pojo Seam components and support classes for them are eligible for hot deploy.
