[Java-SCA] Running the example

Hi,

Downloaded SCA v0.9 / Java. When I try the calculator example, I get:

C:\...\org.apache.tuscany.sca\samples\calculator>ant run
Buildfile: build.xml

run:
     [java] Exception in thread "main"
javax.xml.stream.FactoryConfigurationError: Provider
javax.xml.stream.XMLInputFactory could not be instantiated:

)
     [java]     at
calculator.CalculatorClient.main(CalculatorClient.java:31)
     [java] Java Result: 1

BUILD SUCCESSFUL
Total time: 12 seconds

I guess I miss something in the classpath, but I am a little lost.

Jean,

Are you running with Java 6?  We have had a report of this problem 
previously when people were running Tuscany with Java 6.

Without having checked in detail, I suspect that this problem is caused 
because we build and test Tuscany on Java 5.  In Java 5, the XML stream 
API is not part of the JDK and so Tuscany adds it in through the use of 
the the Woodstox streaming parser.  In Java 6, there is an 
implementation of the XML stream API built into the base JDK.  I suspect 
that there must be a clash between the Woodstox parser and the built-in 
parser.  We shall have to investigate further to find a fix.

In the short run, I'd recommend running Tuscany with some version of Java 5.


Yours,  Mike.
