It works

+ +

This Web app runs a sample Tuscany runtime shell similar to samples/launcher-shell.
+To see how it works and what configuration commands are supported, just read the Shell program's source code.

+ +

Configuration commands can be provided through a text document served from a Web location, for example:
+http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/launcher-shell/scripts/test-start.txt

+ +

To run that particular configuration script just point your Web browser to:
+http://localhost:8080/scashell/run?conf=http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/launcher-shell/scripts/test-start.txt
+To run the script again and refresh the runtime shell, just refresh that page in your Web browser. +

+ +

Sample configuration script samples are available in the Tuscany Subversion repository there. + + + -- cgit v1.2.3
