Hi.I'm back again with my weekly progress. Not easy at all to write after
each week, and i hope i won't soon give up.

Stage 2 Running Tuscany SCA from Android

Running the existing version of calculator-android fires the following error
in the android Logcat:

Regarding my experience with Abdera, the tweakings i performed with the
calculator-android, and the openness of android, i suggest these:

   - Creating an eclipse workspace for tuscany’s projects on which the
   calculator-android depends on;
   - Replacing their references to the JRE library by another reference but
   to Android Library (android.jar)
   - Replacing all references to external jars by relevant projects source
   code. I first thought that checking out those projects in the workspace will
   be ok but as they include android’s native packages namespace (ex:
   javax.xml), they’ll surely for security reason will be rejected at launch by
   android (java.lang.verifyError exceptions). I guess the solution now will be
   to rebuild the android.jar with the sources of these projects.

   I’ve listed projects that should be included in the calculator-android
   build path, and create a new workspace with’em and the calculator-android
   project.

   tuscany-assembly
   tuscany-assembly-xml
   tuscany-assembly-xsd
   tuscany-binding-sca
   tuscany-binding-sca-xml
   tuscany-contribution
   tuscany-contribution-impl
   tuscany-contribution-java
   tuscany-contribution-namespace
   tuscany-contribution-xml
   tuscany-core
   tuscany-core-databinding
   tuscany-core-spi
   tuscany-databinding
   tuscany-databinding-jaxb
   tuscany-definitions
   tuscany-definitions-xml
   tuscany-endpoint
   tuscany-extensibility
   tuscany-host-android(embedded)
   tuscany-implementation-java
   tuscany-implementation-java-runtime
   tuscany-implementation-java-xml
   tuscany-implementation-node
   tuscany-interface
   tuscany-interface-java
   tuscany-interface-java-jaxws
   tuscany-interface-java-xml
   tuscany-monitor
   tuscany-node-api
   tuscany-node-impl
   tuscany-policy
   tuscany-policy-xml
   tuscany-policy-xml-ws
   tuscany-sca-api
   tuscany-sca-api-extensions
   tuscany-workspace
   tuscany-workspace-impl
   tuscany-workspace-xml
   tuscany-xsd

   I then build a list of the needed jars, and have started downloading
   their source code. Here are the concerned projects:

   easymock-2.4 --ok
   axiom-api-1.2.7 --ok
   axiom-impl-1.2.7 --ok
   commons-logging-1.1.1 --ok
   geronimo-activation_1.1_spec-1.0.1 --ok
   geronimo-javamail_1.4_spec-1.2 --ok
   geronimo-stax-api_1.0_spec-1.0.1 --ok
   jaxen-1.1.1 --ok
   junit-4.5 --ok
   neethi-2.0.4 --ok
   stax-api-1.0-2 --ok
   wstx-asl-3.2.4 --ok
   activation-1.1 --ok
   cglib-nodep-2.2 --ok
   jaxb-api-2.1 --ok
   jaxws-api-2.1 --ok
   XmlSchema-1.4.2 --ok
   jaxb-impl-2.1.7 --ok
   asm-all-3.1 --ok
   groovy-all-minimal-1.5.4 --ok
   jsr-181-api-1.0
   jsr250-api-1.0
   jdk tools (com.sun...)

   *Projects for which i already have sources (svn, cvs, zip & jnlp
   download), are marked “ok”. *

   It just dawned on me that these projects may also have references to some
   jars files. It’s going to be harder then i think. Uploading all these
   projects into my workspace and resolving their dependencies by getting their
   sources too won’t be easy at all.
   Later i’ll add those projects sources to android sources and perform a
   “make sdk”. I hope to have then an “Tuscanily” operational android.jar.

   *Questions:*
   - Can anyone give help on how to have the jsr listed above implementation
      sources?
      - In which directory exactly and how should i organize those source
      files in android sources directory to get them built in the new
android.jar?
      - Is there anyway rebuilding android.jar, using some jar files? Some
      may say that i’m lazy ;.) but!!!!!
