Hi,

These last few days I've been looking into calculator2, as suggested by Luciano. I took a list of necessary modules that Adriano sent me from the calculator2 jars and augmented it until the point in which I received the same error stack trace 1 that he reported in this thread. I am now getting the same errors on the Android Emulator 2 and have posted the error stack trace in 3. An excerpt of this trace is included below and a couple of questions follow it afterwards.

ERROR/AndroidRuntime(2255):

How

can

I

ensure

that

the

composite

containing

the

service

is

being

loaded?

The

full

stack

trace

includes

warnings

for

CompositeBuilderImpl

not

having

the

appropriate

component

references.

This

makes

me

think

that

the

composite

is

not

being

created

and

thus

results

in

the

errors

above.

Am

I

missing

something?

Suggestions

are

welcomed

and

appreciated.

The

resulting

set

of

modules

is

based

on

the

tuscany-runtime2

and

tuscany-api

jars

from

revision

673092.

In

the

context

of

this

thread

4

in

which

grouping

and

aggregating

modules

was

discussed

I

am

now

a

user

looking

to

embed

Tuscany

functionality

in

Android.

The

thread

helped

me

to

identify

the

subset

of

Tuscany

to

port,

it

consists

of

the

modules

shown

below:

android-jdk-classes

tuscany-assembly

tuscany-assembly-xml
