JAXB Unmarshalling Exception when Encountering < and >

ello,

I am getting unmarshalling exceptions at any encounter of sequences &lt; and &gt; in my xml. I tried wrappering the corresponding pieces with CDATA like <![CDATA[&gt;]]>, but the exception still occurs.

I am using the following classes for performing the unmarshalling activities:

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import javax.xml.transform.Source;
import javax.xml.transform.stream.StreamSource;

and the exception takes place in the "f = (Filter) u.unmarshal(s);" part of the code below:

JAXBContext jbc = null;
Unmarshaller u = null;
Filter f = null;
try {
jbc = JAXBContext.newInstance(Filter.class);
} catch (JAXBException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
u = jbc.createUnmarshaller();
} catch (JAXBException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
StringReader sr_xml = new StringReader(filter);
Source s = new StreamSource(sr_xml);
try {
f = (Filter) u.unmarshal(s);
} catch (JAXBException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

I would be grateful for any insights into how to resolve this. thank you for any response!

Can you create a small test case for this?   This definitely seems strange as 
the XML parser should be decoding those just fine.    JAXB shouldn't ever even 
see the encoded form of them.

Hi,
this should not happen in the normal out-of-the-box setup. Maybe you
are using some special XML parser or JAXB implementation that does not
resolve these references?

Regard, aki
