    text
    copied!<p>Below is the absolute trivial, minimal example that demonstrates the problem. Three schema files: <em>A.xsd</em>, <em>B.xsd</em>, <em>C.xsd</em> in the following import configuration:</p> <pre><code>C.xsd ---------------- imports ----------------&gt; A.xsd \ / \---- imports ---&gt; B.xsd --- imports ----/ </code></pre> <p>So <em>A.xsd</em> is imported directly by <em>C.xsd</em> and again indirectly through <em>B.xsd</em>. The problem occurs when trying to run <strong>xjc</strong> (ver. <strong>2.2.4</strong>) on <em>C.xsd</em> when <strong>both</strong> a catalog <strong>and</strong> a binding file is used (even an empty one).</p> <h2>A.xsd</h2> <pre><code>&lt;schema targetNamespace="foo://a" xmlns="http://www.w3.org/2001/XMLSchema"&gt; &lt;simpleType name="year"&gt; &lt;restriction base="dateTime"&gt; &lt;pattern value="\d{4}"/&gt; &lt;/restriction&gt; &lt;/simpleType&gt; &lt;/schema&gt; </code></pre> <h2>B.xsd</h2> <pre><code>&lt;schema targetNamespace="foo://b" xmlns="http://www.w3.org/2001/XMLSchema"&gt; &lt;import namespace="foo://a" schemaLocation="boo://a.xsd"/&gt; &lt;/schema&gt; </code></pre> <h2>C.xsd</h2> <pre><code>&lt;schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="foo://c"&gt; &lt;import namespace="foo://a" schemaLocation="A.xsd"/&gt; &lt;import namespace="foo://b" schemaLocation="B.xsd"/&gt; &lt;/schema&gt; </code></pre> <h2>catalog.xml</h2> <pre><code>&lt;catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"&gt; &lt;system systemId="boo://a.xsd" uri="A.xsd"/&gt; &lt;/catalog&gt; </code></pre> <h2>binding.xjb</h2> <pre><code>&lt;bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.1"/&gt; </code></pre> <p>Given the above files, all placed in the same directory the below invocation succeeds:</p> <pre><code>xjc -d src -extension -catalog catalog.xml C.xsd </code></pre> <p>whereas the following invocation:</p> <pre><code>xjc -d src -extension -catalog catalog.xml C.xsd -b bindings.xjb </code></pre> <p>... <strong>fails</strong> with the bug-like message (pointing to some internal mess-up?):</p> <pre><code>parsing a schema... [ERROR] 'year' is already defined line 8 of file:/home/brutus/A.xsd [ERROR] (related to above error) the first definition appears here line 3 of file:/home/brutus/A.xsd Failed to parse a schema. </code></pre> <h2>UPDATE</h2> <p>Posted a <a href="https://java.net/jira/browse/JAXB-963" rel="nofollow">bug report</a>.</p>
