RE: HELP DEPLOY

Hi Rana,

You can also check this thread in the lists archives:
http://news.gmane.org/gmane.comp.java.smartfrog.user/cutoff=72

Title: "Component Deployment."

The right method to use for deploying and stating a description is 
sfCreateNewChild()

This method deploys the description and calls and guards the sfDeploy and sfStart lifecycle steps in the new component.

You use sfDeployComponentDescription only when you want to control the calls to the lifecycle methods.

To create a component description you can:
- Create the component description at runtime as Flavio described.
- Get the component description for a "extend LAZY" or "DATA" structure from your description
- Get the component description reading a smartfrog file from somwhere: ex "xxx.sf" using the method: 
org.smartfrog.sfcore.componentdescription.
ComponentDescriptionImpl.sfComponentDescription (String url).

(Remember that if you are using securith then the .sf file has to be in a properly signed jar file.)
