Problems using two versions of the same service

[Beta User]

I am having a problem getting a prototype of deploying and using two versions of the same service working. I have a service, SimpleOSGiService and a corresponding Web application which I have created two versions of each. When I deploy only one version of the service bundle and its corresponding Web application everything works as expected. When I attempt to deploy both versions at the same time I am getting conflicts that are exposed based on the order I deploy the services.

I am using the admin console to deploy:

Method 1:
deploy simpleosgiservice-0.1.0.jar
deploy simpleosgiservice-0.2.0.jar
deploy simpleosgiapp-0.1.war
deploy simpleosgiapp-0.2.war

I get an error when deploying simpleosgiapp-0.2.war:
[2008-09-09 17:15:07.312] latform-tomcat-thread-51 <SPDE0018E> Unable to install application from location 'file:/C:/springsource-ap-1.0.0.RC1/work/com.springsource.platform.primordial/upload/simpleosgiapp-0.2.war'. Could not satisfy constraints for bundle 'com.express-scripts.ccs.simpleosgiapp' at version '0.2.0'.
Cannot resolve: com.express-scripts.ccs.simpleosgiapp
Resolver report:
Bundle: com.express-scripts.ccs.simpleosgiapp_0.2.0 - Missing Constraint: Import-Package: com.express_scripts.cus.simpleosgiservice; version="0.2.0"

V0.1 of the app executes correctly.


Method 2:
deploy simpleosgiservice-0.2.0.jar
deploy simpleosgiservice-0.1.0.jar
deploy simpleosgiapp-0.2.war
deploy simpleosgiapp-0.1.war

No errors during deploy but when I execute web app V0.1 I get a NoSuchMethod exception on the class that differs between the two versions. V0.2 of the app executes correctly.

Any help would be appreciated.

Steve, if the simpleosgiservice-0.2.0.jar is not backwards compatible (which it probably isn't reading you get NoSuchMethodError), you have to declare the dependency in simpleosgiapp-0.1.war as com.express_scripts.cus.simpleosgiservice;version= "[0.1.0,0.2.0)". Version range "0.1.0" means "[0.1.0,Infinity)" as far as I am concerned.

Because of this, when you deploy simpleosgiapp-0.1.war, it picks up simpleosgiservice-0.2.0.jar.

I have changed the manifest in the war to import the package as follows:

simpleosgiapp-0.1.war:
com.express_scripts.cus.simpleosgiservice;version= "[0.1.0,0.1.0]"

simpleosgiapp-0.2.war:
com.express_scripts.cus.simpleosgiservice;version= "[0.2.0,0.2.0]"

Again, when I deploy only one version of the service bundle and its corresponding Web application everything works as expected. When attempting to deploy both versions of the service and web application I run into problems.

Method 1:
deploy simpleosgiservice-0.1.0.jar
deploy simpleosgiservice-0.2.0.jar
deploy simpleosgiapp-0.1.war

deploy simpleosgiservice-0.2.0.jar
deploy simpleosgiservice-0.1.0.jar
deploy simpleosgiapp-0.2.war

V0.2 of the web application executes as expected. Am I missing something obvious? It seems like this should work.

Steven,

This looks strange. If you don't mind, can you create a JIRA and include your bundles at attachments.

JIRA can be found at: https://issuetracker.springsource.com/.
