ClassNotFoundErrors on calculator-android after translating SCA and
mobile-android code with Retrotranslator
------------------------------------------------------------------------------------------------------------
Key: TUSCANY-2440
URL: https://issues.apache.org/jira/browse/TUSCANY-2440
Project: Tuscany
Issue Type: Improvement
Components: Java SCA Core Runtime
Affects Versions: Java-SCA-1.2
Environment: Mac OS X 10.5, Maven version: 2.0.6, java version
"1.5.0_13", Apache Ant version 1.7.0
Reporter: Oscar Castaneda
Priority: Minor
The current Android SDK does not support Annotations, as a result
calculator-android runs with Annotation related errors. A suggested workaround
[1] for issues related to Annotations is to translate source code with
Retrotranslator [1]. After succesfully translating the SCA modules and modified
Android modules with Retrotranslator the Annotation related errors cease.
However, running calculator-android results in ClassNotFound errors for
java.rmi.Remote in the first test and java.beans.Introspector in a more recent
test.
Three workarounds have been suggested:
1) Comment out all the code that uses the RMI API
2) Follow suggestions in [3] to either replace java.rmi.Remote with
java.lang.Cloneable (as the result of using a retrotranslator option) or taking
the RMI source from Apache Harmony and putting it in a retrotranslated JAR.
3) Removing RMI should be as simple as removing the tuscany-binding-rmi
dependency from host-android.
Upon failure of these workarounds the alternative is to minimize the number of
component types supported (java) and bindings (default sca binding) and then
try to run the calculator sample application. When calculator-android runs
successfully further steps will be discussed on dev-list.
