Major consumability issues with new Node and Domain APIs
--------------------------------------------------------
Key: TUSCANY-2409
URL: https://issues.apache.org/jira/browse/TUSCANY-2409
Project: Tuscany
Issue Type: Bug
Affects Versions: Java-SCA-1.3
Environment: All
Reporter: Simon Nash
Fix For: Java-SCA-1.3
The recent change to remove the previous domain/node implementation has created
severe usabliity issues for the callback-ws-client and callback-ws-server
samples.
1. In callback-ws-client, MyClientImpl, the line
SCANode node =
SCANodeFactory.createNodeWithComposite("myapp.composite");
was changed to
SCANode2 node =
SCANode2Factory.newInstance().createSCANode("target/classes/myapp.composite",
new SCAContribution("test", "target/classes"));
2. In callback-ws-client, CallbackClientTestCase, the line
node = SCANodeFactory.createNodeWithComposite("callbackws.composite");
was changed to
node =
SCANode2Factory.newInstance().createSCANode("jar:file:../callback-ws-service/target/sample-callback-ws-service.jar!/callbackws.composite",
new SCAContribution("server",
"../callback-ws-service/target/sample-callback-ws-service.jar"));
3. In callback-ws-server, CallbackServer, the line
SCANode node =
SCANodeFactory.createNodeWithComposite("callbackws.composite");
was changed to
SCANode2 node =
SCANode2Factory.newInstance().createSCANode("target/classes/callbackws.composite",
new SCAContribution("test", "target/classes"));
4. In callback-ws-server, CallbackServerTestCase, the line
node = SCANodeFactory.createNodeWithComposite("callbackws.composite");
was changed to
node =
SCANode2Factory.newInstance().createSCANode("target/classes/callbackws.composite",
new SCAContribution("test", "target/classes"));
The complexity of these APIs, and the need to embed hard-wired paths and jar
names, is unacceptable for a simple sample. This is "must fix" for the 1.3
release.
It would also be good to convert more samples from the previous host-embedded
APIs to the new domain/node APIs, but this can't happen until the consumability
problems are fixed.
Ideally we would have a "convenience" API similar to the previous
createNodeWithComposite() API. This API would call the other more complex APIs
under the covers.
