calculator-scaclient example

[Orhan Aksoy <oa...@gmail.com>]

Hi all,

I cannot get the calculator-scaclient example to run. Here's what I have
tried:

To run the sample, first I start the contribution-calculator.

> cd tuscany-sca-2.0-M5\samples\binding-sca\contribution-calculator
> mvn tuscany:run

Then, I see the [INFO] logs, and at the end, I see

SCA API ClassLoader: org.codehaus.classworlds.RealmClassLoader@b8bef7
3 + 2=5.0
3 - 2=1.0
3 * 2=6.0
3 / 2=1.5
[INFO] Ctrl-C to end...


Then I run the sca client

> cd tuscany-sca-2.0-M5\samples\calculator-scaclient
> mvn exec:java

After the CalculatorService.add(2, 3) call, the program blocks for a few
seconds, then I get the connection lost message.
The output is as follows:

That is actually working. If you look closely in the output you'll see
the line with "5.0" which is the expected result from the calculator
service of adding 2 and 3.

The output does get lost amongst that connection lost WARNING message
which can be ignored, its coming from Hazelcast and the message will
stop appearing when Tuscany updates to a more recent hazelcast
release.
