JAXB SAXParseException while generating models from *.xsd delivered by EURID (EPP Protocol)

Question

I'm trying to generate Java code from the *.xsd files delivered by EurID.

Currently I'm receiving several exceptions:

Error while parsing schema(s).Location [ file:~/src/main/resources/epp-1.0.xsd{375,32}].
org.xml.sax.SAXParseException; systemId: file:~/src/main/resources/epp-1.0.xsd; lineNumber: 375; columnNumber: 32; src-resolve: Cannot resolve the name 'eppcom:minTokenType' to a(n) 'type definition' component.

For the reference host.xsd file contents is here: http://pastebin.com/ZdAGrNXF and eppcom.xsd is here: http://pastebin.com/hYSwXQ11

I've already spent like 5 days trying to figure out what is wrong - trying different combinations of maven plugin options etc. The SO's community is my last chance now. Thank you in advance for the tips.

Answer 1

I had the same problem trying to validate xml with epp-1.0.xsd (http://www.iana.org/assignments/xml-registry/schema/epp-1.0.xsd) and replacing

<import namespace="urn:ietf:params:xml:ns:eppcom-1.0"/>

in epp-1.0.xsd file with

<import namespace="urn:ietf:params:xml:ns:eppcom-1.0" schemaLocation="http://www.iana.org/assignments/xml-registry/schema/eppcom-1.0.xsd"/>

solved the problem.

Answer 2

The JRE/JDK I've used was not complete somehow. Installation of JDK with Java EE solved the problem of JaxB.

Answer 3

I am changed xsd. Add attribute schemaLocation to import elements in all xsd schemas. Then generating of class was ok.

If I use catalog for resolving namespaces, then I have problems with duplicit definition of some elements.
