Optimize JDK WireService
------------------------
Key: TUSCANY-690
URL: http://issues.apache.org/jira/browse/TUSCANY-690
Project: Tuscany
Issue Type: Improvement
Components: Java SCA Core
Affects Versions: Java-M2
Reporter: Venkatakrishnan
Attachments: Tuscany-kernel-core-jdkwireservice-Sept-4.diff
This is going to involve several things.
To begin with Jim Marino had suggested the creation of dynamic classes for the
proxies (instead of java.lang.reflect.Proxy) using ASM and bytecode generation.
Please refer to the thread
http://www.mail-archive.com/tuscany-dev%40ws.apache.org/msg07271.html
Here is a patch that changes the 'createProxy' method of the JDKService class.
It generates bytecodes for a proxy implementation class for the wire's
interface. It then instantiates this class and returns it (instead of an
instance of java.lang.reflect.Proxy as it used to before). After instantiation
this proxy is set with the chains that correspond to each of the service
methods. Hence during invocation there is no seek into a map based on the
invoked method, to find the right chain. The invocation is made with right
chain directly.
I have been able to successfully compile and run most of the testcases. But a
few fail since there are assetions that check if the proxy generated is of
'java.lang.relect.Proxy' type, which obviously is not. Before I go ahead and
make those changes I would like to know if the current implementation is fine.
I have tested the JavaScript testcases after these changes to the wiring and
they work.
Thanks
