<p class="MsoNormal">Sorry if I was mis-interpreting what you are originally doing. The other thread poster was literally new()-ing a AuthnRequestBuilder() or something, which is bad because as Scott said it's an implementation class. Casting to KeyInfoBuilder
is different, but still discouraged for the same reasons.<br>

<pre>Well that makes sense I think. So, more like this then?<o:p></o:p></pre>

<pre>Yes, or cast to the SAMLObjectBuilder specialization, but same difference.<o:p></o:p></pre>
<p class="MsoNormal"><br>
<br>
Almost, but have to be careful. The stuff in opensaml-xmlsec-impl doesn't know anything about SAML. So the builders don't implement SAMLObjectBuilder. For example, the signature-oriented ones implement XMLSignatureBuilder, the encryption ones are XMLEncryptionBuilder.
What those interfaces (along with SAMLObjectBuilder) add is the no-arg buildObject() method. They're all sub-interfaces of XMLObjectBuilder, which doesn't have such a method, only methods which take element and/or type QNames (or the constituent inputs).
There was a reason why Chad designed things that way, although off-hand I don't remember.<br>
<br>
So the real answer to your original question is either:<br>
<br>
1) cast the builder you get to XMLObjectBuilder<KeyInfo>. Then you have to call buildObject(KeyInfo.DEFAULT_ELEMENT_NAME).<br>
<br>
2) cast the builder to XMLSignatureBuilder<KeyInfo>. Then you can just call buildObject().<br>

<br>
Yeah, I guess those examples in the wiki docs are really targeting SAMLObjects specifically. Per the above, they're not completely accurate for the non-SAML schemas. The concepts are the same, just not some of the specifics.<br>
