Hi Dennis
I thought I'd try to get JiBX to generate a .XSD file from my
binding. I understand SchemaGen can sometimes accomplish this,
but is not supported for all user-defined bindings. I the
NullPointerException below in case it is easily resolved.
I have two instances in my binding where a <collection> contains a
<structure>. In each of these cases I get an NPE at at
org.jibx.schema.generator.SchemaGen.setDocumentation(SchemaGen.java:234).
It occurs because the domain class to which the <structure> is
mapped does not appear in the Map m_classmap within class
PackageCustom. So pack.get(classname) returns null, and
subsequently null.isUseJavaDocs() throws the NPE.
Further details will be made available if required.
Many thanks, Robin.
My binding constructs are (these are just extracts):
<mapping name="pointer"
class="net.uk.roos.configurator.server.domain.Pointer">
<value name="name" field="name"/>
<collection field="revIdAttributionList">
<structure name="revId"
type="net.uk.roos.configurator.server.domain.RevIdAttribution">
<value name="workstream" field="workstream"
style="attribute"/>
<value field="revisionIdString"
style="text"/>
</structure>
</collection>
</mapping>
<mapping name="configurator"
class="net.uk.roos.configurator.server.domain.Configurator">
<collection field="environments" name="environments"/>
<collection field="workstreams" name="workstreams"/>
<collection field="pointers" name="pointers"/>
<collection field="issues" name="issues"/>
<collection field="workstreamConfig">
<structure name="revisions"
type="net.uk.roos.configurator.server.domain.WorkstreamSpecificConfiguration">
<value name="workstream" field="workstreamName"
style="attribute"/>
<collection field="revisions"/>
</structure>
</collection>
</mapping>
And the NPEs are thrown during processing of the RevIdAttribution
and WorkstreamspecificConfiguration classes.
My command-line arguments to SchemaGen are:
-n uri=http://net.uk.roos.configurator.schema.1.0 -s
C:\projects\configurator\configurator\configurator-server\src\main\java
-v
C:\projects\configurator\configurator\configurator-server\src\main\config\binding.xml
The console output and exception is as follows:
