Re: problem with ""rus as tuscany"

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

Subject: 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:
