Constructor Detail

JavaPackageImpl

public JavaPackageImpl()
                throws java.rmi.RemoteException

Throws:

java.rmi.RemoteException

Method Detail

sfDeploy

public void sfDeploy()
              throws SmartFrogException,
                     java.rmi.RemoteException

Called after instantiation for deployment purposed. Heart monitor is started and if there is a parent the deployed component is added to the heartbeat. Subclasses can override to provide additional deployment behavior.

Specified by:

sfDeploy in interface Prim

Overrides:

sfDeploy in class PrimImpl

Throws:

SmartFrogException - error while deploying

java.rmi.RemoteException - In case of network/rmi error

sfStart

public void sfStart()
             throws SmartFrogException,
                    java.rmi.RemoteException

Can be called to start components. Subclasses should override to provide functionality Do not block in this call, but spawn off any main loops!

Specified by:

sfStart in interface Prim

Overrides:

sfStart in class PrimImpl

Throws:

SmartFrogException - failure while starting

java.rmi.RemoteException - In case of network/rmi error

readValuesAndSetUpClasspath

public void readValuesAndSetUpClasspath()
                                 throws SmartFrogException,
                                        java.rmi.RemoteException

this method does the core of the work

1. read in the attributes
2. fetch the current codebase if needed
3. flatten the filelist
4. extract URIs from everything
5. merge duplicates
6. create (and set) the output attributes

   Throws:

   SmartFrogException

   java.rmi.RemoteException

checkForRequiredClasses

public void checkForRequiredClasses()
                             throws SmartFrogException

look into the classpath and load the classes, then verify that any needed declared required classes are actually present. Throw a liveness exception if not

Throws:

SmartFrogException

getUriClasspathList

public java.util.Vector getUriClasspathList()

get the vector of uris

Specified by:

getUriClasspathList in interface JavaPackage

Returns:

the classpath as a vector
