Hi Julian (or others),
I have implemented this as an MBean that instantiates each portlet instance
during its start method, and destroys them again during the stop method.
Before instantiation however I check if the instance name is already used, if
so I write a warn to the log.
The first time
OK, now that I have been directed to instantiating the foreign portlet
programatically, I've tried.
I'm doing things from a servlet's init method. Now please do not tell me to use
an MBean. It doesn't fit in my environment, and it should be possible to do it
from a servlet's init method,
I have implemented it as follows:
ValueMap preferences = instance.getPreferences();
| while (iterator.hasNext())
| {
| Element preference = (Element) iterator.next();
| String name = preference.valueOf(PREFERENCE_NAME);
| Value originalValue = preferences.getValue(name);
|
at the end preferences are stored as strings in the db with an integer which
says what data type it is.
this is the potential usage as in reality we only use strings because JSR168
does not support more than that (unless you write your extension).
what is the interface you are using ?
Hi,
I am currently implementing the above mentioned component, and I would much
appreciate if someone can explain me how I can create a typed Value instance
for the preferences?
Does JBoss portal provides any means for retrieving th etype of a preference
value or do I have to implement this
Peter thank you for clarifying that, and Julian thank you for showing how to
get hold of the instance container.
We will work on an MBean based solution that inserts its definitions using the
instance container.
Grtz,
Marcel

If you write an MBean, the best way is to inject it into your MBean using :
|mbean ...
| ...
| depends
| optional-attribute-name=InstanceContainer
| proxy-type=attributeportal:container=Instance/depends
|...
|mbean

Hi Julian (or others),
Can you please explain what the best way is to get hold of the
InstanceContainer object?

To clear up my earlier post, I am not implying that I can have a war file with
just a porltet-instances.xml file and an *-object.xml file. That will not work
because the Portal ignores portlet-instances.xml files if there is no portlet
to deploy. Thus, I need to declare at least one porltet,
We would like to NOT define the specific instances including all its parameters
in the portlet war file. This would mean that we need to repackage the war file
each time an instance needs to be added.
We want to create a separate war file that contains the portal definition in a
Today what you want is not possible anymore due to the issue I explained before
(portlets may be deployed before the -object.xml file).
However it is possible to do it programatically using the services I explained
before.
What could be possible is to have the insertion of XML files using JMX,
portlet-instances.xml file have to be packaged with a war file because they
require the portlet to be present and the only way to achieve that is by doing
such a deployment.
otherwise the -instances.xml file could be created before the war file
containing the portlet is deployed.
you still
Consider this situation. I have a portlet in a war file, and in the
portlet-instance.xml file I declare an instance of my portlet, and also create
an instance of, for example, CMSPortlet. On 2.4.x, I can deploy my war file and
get both my portlet and the CMSPorltet instances. Are you saying
2.6 work the same as 2.4 works, so there may be some misunderstanding here.
What is not possible in 2.4 and 2.6 is to create portlet instances in
-object.xml outside of war files.
