I tried a brute-force approach in which I trapped the two calls to
PackageCustom.getClassCustomization(String name) for the cases
which I knew would return null, and at that point invoked
PackageCustom.addClassCustomization(String name) and set
m_useJavadoc=new Boolean(false) before letting each invocation
return. So the NPE was suppressed and execution continued.
I now see three types of log message:
-----
Warning: Handling not implemented for unspecified mapping; on
collection element at (line 3, col 43, in binding.xml)
This occurs for every <collection> element, even though a
<mapping> element is present with class set to the type of the
collection, e.g.
2 <mapping name="repository"
class="net.uk.roos.configurator.server.domain.Repository">
3 <collection field="applications"/>
4 </mapping>
5
6 <mapping name="application"
class="net.uk.roos.configurator.server.domain.Application">
<!-- value mappings defined here -->
9 </mapping>
In this case, line 3 refers to an attribute of class Repository
which is of type ArrayList<Application>, and a mapping for class
Application is defined at line 6.
-----
Warning: No schema equivalent known for type - treating as string;
on value element at (line 62, col 81, in binding.xml)
62 <value style="attribute" name="issueRef"
field="issue" ident="ref"/>
This defines an attribute the value of which must be separately
declared in a different XML element. I'm happy for that to be
treated as unconstrained text in the .XSD if there is no
equivalent in XML Schema.
-----
Error: Unsupported component; on value element at (line 52, col
72, in binding.xml)
49 <collection field="revIdAttributionList">
50 <structure name="revId"
type="net.uk.roos.configurator.server.domain.RevIdAttribution">
51 <value name="workstream" field="workstream"
style="attribute"/>
52 <value field="revisionIdString"
style="text"/>
53 </structure>
54 </collection>
55 </mapping>
Line 52 is defining the text element content for one of the two
"structures within a collection" for which I had to force my way
past the NPE, so it does not surprise me that there should be
further trouble here.
-----
I think you'll all agree there is little point my continuing at
this stage. But if anyone has further suggestions, or if it is
conceivable that SchemaGen could easily be extended to accommodate
these binding constructs and at least generate a viable (albeit
sub-optimal) .XSD then that would be great.
Cheers, Robin.
