We have this object that exists in the servlet session that I want to make
available to inject into other Seam components. So I tried to create a factory
pattern object:
public class SessionObjFactory {
|
| public ParamBean getParamBean()
| {
| return
(ParamBean)Contexts.getSessionContext().get(SessionConstants.PARAMS);
| }
|
| public void setParamBean(ParamBean params)
| {
| Contexts.getSessionContext().set(SessionConstants.PARAMS, params);
| }
|
| }
and specified a SessionObjFactory.component.xml (wanted to use the auto-create
option which does not seem to be available in the Factory annotation).
<component>
<factory name="paramBean" value="#{sessionScope.paramBean}"
scope="session"/>
</component>
on startup I see the following exception:
17:11:05,069 ERROR [[/]] Exception sending context initialized event to listener

What is going on I thought the factory pattern can be used to create any Pojo
object? I can't find any documentation for having to create some Converter
object for factories?
