I presume you want: <colocationGroup> <groupGenerator class="a.b.c.D1" forType="a.b.c.X1" /> <groupGenerator class="a.b.c.D2" forType="a.b.c.X2" /> <groupGenerator class="a.b.c.D3" forType="a.b.c.X3" /> </colocationGroup > in which case you'd need: @XmlAccessorType(XmlAccessType.PROPERTY) class ColocationGroupCfg ... { List<GroupGeneratorCfg> groupGeneratorCfgs = new LinkedList< GroupGeneratorCfg>(); @XmlElement(name="groupGenerator") public void setGroupGeneratorCfgs(List<GroupGeneratorCfg> l) { ... } } class GroupGeneratorCfg ... { @XmlAttribute(name="class") String clazz; @XmlAttribute String forType; } Vladimir can confirm though, he's our resident JAXB wizard. :) On 18 May 2011, at 15:17, Pete Muir wrote: -- Manik Surtani manik(a)jboss.org twitter.com/maniksurtani Lead, Infinispan http://www.infinispan.org
