Unmarshalling an XML fragment representing a JAXB object without XmlRootElement I've recently had a requirement to unmarshal an XML fragment that was passed into one of my services. This in itself is typically not and issue and I've written code that does that plenty a time, however in this case I was having to unmarshal a fragment for a complex type, not for an element. That's where it got a little bit more complicated.
Compiling the FHIR schema with XJC I've written previously about fixing HL7 CDA schema compilation with XJC, now that I've been looking at FHIR it seems that there are name collisions in that schema too. The actual problem arises out of the W3C XHTML 1.0 Schema and not the FHIR schema per se.
Generate JAXB jar from a Maven dependency that has multiple referenced schemas I've been trying to get the maven-jaxb2-plugin to generate a JAXB jar out of XSDs that are stored inside a dependency that I have no control of. This was quite doable for a simple, single XSD Maven dependency that didn't import any other schemas, but when dealing with a more complex schema that did import multiple other XSDs from the same dependency jar, it didn't "just" work. After trying many approaches I found a solution however.
Generate XML Schema documentation the easy way with XS3P I have to work with the CDA XML schema on a regular basis and sometimes it is easier to check things either via a tool that can visualise the schema or through hyperlinked documentation that describes the schema in a concise way. Unfortunately, as I found out, most tools can't handle a complex schema that has multiple cyclic references within it. So what's the solution? Use a tool that doesn't analyse the XSD! This is where xs3p comes in.
JiBX fails to generate Java XML bindings for schemas with circular references I wanted to compare how JiBX stacks against JAXB in terms of performance. From their website, they claim "It also provides very high performance, outperforming all other Java data binding tools across a wide variety of tests.". This sounded great, especially since I've identified that JAXB is a bottleneck. I downloaded JiBX 1.2.6 and proceeded to generate my bindings, only to find that it could not handle my schema.
