Re: sfManagementConsole &SFScriptExecutionImplnot being Serializable

For some reason the sfExport flag in the shell components is set to
false.

We did this because we did not want the exec interfaces to be remotely
accessible for security resons. Consequently, when it tried to serialize
the component, it does nor serialize the stub, but the component itself.
Very few prims, if any, can actually be serialized as components (and
anyway, this is not what you want).

I am not sure that we needed to be quite so strict, as the key
interfaces are not Remote anyway. Thus we could probably have set the
sfExport to true reasonably safely.

So if it matters to you that unExported components generate this effect
in the console - set the sfExport flag to true. )You might also have to
build the stub, depending on the release you are using.)

Use a console deployed directly in the host where SFScriptExecution is
deployed and it will talk to it directly.

You will find that any component that contains Streams cannot be
serialized.

SFScriptExecution uses java exec() that cannot be serialized and that is
why you get that message.

BTW, does the console crash or throws and exception?

Subject: [Smartfrog-developer] sfManagementConsole &
SFScriptExecutionImplnot being Serializable

Hello,

We're having some trouble here with the sfManagementConsole : an
attribute of one of our components is
  shell LAZY ATTRIB myShell;
where myShell is an instance of SFScriptExecutionImpl.
So, when the management console tries to display our component, it
crashes with an RMi exception, as SFScriptExecutionImpl is not
Serializable.

What could we do as a workaround ? Plus, I thought that all Prims were
supposed to be Serializable ?

Thanks for your help,
