Subject: Using Tuscany for dynamic component loading
Hi All,
I am wondering whether the Tuscany is able to perform dynamic component
loading at runtime. I would like to have the Tuscany runtime as an
execution environment for my service components to be composed on the fly.
Firstly, can i do it?
Yes, you can do it. There are two ways to construct a Composite model
programtically:
1) Use the factories (modules/tuscany-assembly)
2) Use the DSL (modules/tuscany-assembly-java-dsl, an
example:org.apache.tuscany.sca.assembly.dsl.BigBankBuilder.java)
also, another thing is that when I run the calculator example, it
specifies a composite file for service components. what happen if I want
to write my own program, how can I tell the Tuscany runtime where to look
for this composite file?
The composite file will be scanned from the archive automatically. You can
write a file META-INF/sca-contributions.xml to list all the deployable
composites (QNames). Please see
http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/samples/implementation-composite/src/main/resources/META-INF/sca-contribution.xml.
