problem with ""rus as tuscany"

Hi all! 
I found a pdf tutorial on the net which title reads "FirstStepsWithSCADesigner". I follow correctly each step twice but something doesn't work.

Could someone help me?


When I compile the client class(in the package src/test) i get this:

4-nov-2008 18.06.17 org.apache.tuscany.sca.assembly.xml.CompositeProcessor
AVVERTENZA: No namespace found: Composite = Restaurant

whereas if a run as tuscany the restuarant.composite I get this:

Hi Marco

I have to admit that I haven't tried the STP tooling. What versions of STP
and Tuscany are you using?

The problems you are seeing are caused by problems in the composite file. Is
the restaurant.composite generated by STP or did you type it in manually.
For example,

The warning about "no namespace found" won't stop it working but mean the
composite description should look something like.

<sca:composite xmlns:sca="http://www.osoa.org/xmlns/sca/1.0"
           targetNamespace="http://restaurant"
           xmlns:restaurant="http://restaurant"
           name="Restaurant">
etc.

The errors are more serious. The BillServiceComponent doesn't seem to be
providing a reference called tipService for some reason. Can you compare
what you have against some of our examples. E.g. take a look at our basic
Calculator sample (
http://svn.apache.org/repos/asf/tuscany/java/sca/samples/calculator/). If
you can't see anything obviously wrong post your BillServiceImpl and your
composite file?

Regards

Simon

Re: problem with ""rus as tuscany"

Posted by Raymond Feng <en...@gmail.com>.
Looks like the fatal error is "javax.xml.stream.XMLStreamException: 
Non-default namespace can not map to empty URI (as per Namespace 1.0 # 2) in 
XML 1.0 documents". A similar issue has been reported by 
https://issues.apache.org/jira/browse/TUSCANY-2631.

Can you find the violating XML document with the following pattern? Please 
note a non-default namespace ns1 is now mapped to "".

<deployable xmlns="http://www.osoa.org/xmlns/sca/1.0" composite="ns1:dfsdf" 
xmlns:ns1=""></deployable>

My interpretation is that the XML is not valid per the XML namespace 
statement: http://www.w3.org/TR/xml-names/

[Definition: If the attribute name matches PrefixedAttName, then the NCName 
gives the namespace prefix, used to associate element and attribute names 
with the namespace name in the attribute value in the scope of the element 
to which the declaration is attached. In such declarations, the namespace 
name may not be empty. ]

You probably have to do this way:

<sca:deployable xmlns="" composite="xyz" 
xml:sca="http://www.osoa.org/xmlns/sca/1.0"/>

Thanks,
Raymond
