Ron Gavlin commented on TUSCANY-711:
------------------------------------
After further investigation, I have confirmed this is definately a Tuscany SDO
problem with class SDOXSDEcoreBuilder. The problem is caused by a limitation in
Tuscany's efforts to override the standard EMF name-mangling algorithm.
Problematic-Line 226 of SDOXSDEcoreBuilder is as follows:
/**
* Override default EMF behavior so that the name is not mangled.
*/
protected String validName(String name, int casing, String prefix) {
return name;
}
For namespace "http://www.example.com/simple-1";, this method is eventually
called with parameters ("1", 2, "_"). The EMF NameMangler base class would
return the correct value, "_1". The SDO-overridden method returns "1" which
eventually gets used incorrectly as a namespace prefix. I can see a few fixes
to this problem:
1. Modify SDOXSDEcoreBuilder.validName to handle this special case. I am not
sure this is correct.
2. Add override method SDOXSDEcoreBuilder.getEPackage(XSDNamedComponent
xsdNamedComponent). Reimplement the method replacing the invocation of
qualifiedPackageName(targetNamespace) with
SDOXSDEcoreBuilder.getDefaultPackageName(targetNamespace)
3. Add override method SDOXSDEcoreBuilder.qualifiedPackageName(String
targetNamespace) which simply delegates to
SDOXSDEcoreBuilder.getDefaultPackageName(targetNamespace). This looks like the
most straightforward solution. Are there drawbacks?
This is a showstopper problem for us. Any guidance would be appreciated.
Thanks in advance,

> Project: Tuscany
> Issue Type: Bug
> Components: Java SDO Implementation
> Affects Versions: Java-M1
> Environment: Win2K Sun JDK 1.4.2_11
> Reporter: Ron Gavlin
> Priority: Critical
>
> The Tuscany SDO Serializer generates an invalid namespace prefix for
> namespaces that end with a '-' followed by a number.
> For example, Tuscany SDO generates the invalid namespace prefix "1" for
> namespace http://www.example.com/simple-1. Any DataObjects saved with the
> .../simple-1 namespace cannot be subsequently loaded.
> I suspect this may be an EMF bug.
