jaxb:extensionBindingPrefixes by disabling the strict mode or by using the extension

http://maven.40175.n5.nabble.com/Error-during-compiling-xsd-s-using-maven-xjc-td3779661.html

Hi

When i try to compile and generate java files using jaxb through xjc maven plugin i am getting the error.

Please suggest how to use the jaxb:extensionBindingPrefixes by disabling the strict mode or by using the extension

The issue is because in the xsd schema in using jaxb:extensionBindingPrefixes="xjc" as follows:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
            xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
            jaxb:extensionBindingPrefixes="xjc"
            elementFormDefault="qualified"
            jaxb:version="2.0">

[ERROR] file:/C:/mvnExample/SampleConfig.xsd[16,32]
org.xml.sax.SAXParseException: vendor extension bindings (jaxb:extensionBindingPrefixes) are not allowed in the strict mode. Use -extension.

You can try by adding <extension>true</extension> under <configuration> </configuration> in your pom file

 

============

http://jaxb.java.net/nonav/2.2.3u1/docs/xjc.html

-extension

By default, the XJC binding compiler strictly enforces the rules outlined in the Compatibility chapter of the JAXB Specification. Appendix E.2 defines a set of W3C XML Schema features that are not completely supported by JAXB v1.0. In some cases, you may be allowed to use them in the "-extension" mode enabled by this switch. In the default (strict) mode, you are also limited to using only the binding customizations defined in the specification. By using the "-extension" switch, you will be allowed to use theJAXB Vendor Extensions.
