Re: [Smartfrog-support] sfStart and program arguments

[Guijarro, J. <jul...@hp...>]

Hi Gary,

Welcome to the list.

What I get from your question is that you are trying to pass some java
properties to a program that is deployed using sfStart. If my
understanding is correct then what you need to do is to have a daemon
that either was started with those parameters included on the command
line or you will need your component to use something like system
properties to get those parameters to your other program.

sfStart is used to parse a description and verify that everything is
correct and then to pass that description to the daemon. Then, the
daemon is the one that deploys the components that will load your
application.

To start a daemon with special parameters you can use -J . For example:
rem JVMARGS are declared using -J token=20
rem e.g. -J "-Djava.library.path=3D/libs -Xmx400M"
rem e.g. -J "-Djava.library.path=3D/libs" -J -Xmx400M

If you use SmartFrog with security on you will find that SmartFrog uses
the Java Security Manager and also needs a java security policy file.
This file is set in the script setSFSecurityProperties. For both to work
together, you should merge all the security policies in one file. If you
only need that policy file because or RMI, and you don't care about its
restrictions, then you could enable the "all permitted" policy file that
we have for dynamic classloading with no security by just removing the
comment (#) in

# export SFDYNAMICCLASSLOADING_ON=3DENABLED

I haven't tried it but to hard code a security policy in a java program
you could try this:

String myFile=3D"....";
System.setProperty("java.security.policy",myFile);
System.setSecurityManager(new SecurityManager());
