Re: [xmlblaster] Errors when testing C-API

Many Thanks. I tried it and it seems like they are
transforming &lt; to < at some point.



Here is the predicate that I am submitting:


Submitted Predicate:
/xmlBlaster/key[metadata/BasicTemporal/beginning_date_time_
group/hour_time &lt; 22 ]




and the exception that it pushes back is:



org.infospherics.commonAPI.impl.exception.PlatformFailureException:
XmlBlasterEx
ception errorCode=[resource.configuration]
serverSideException=true location=[Sa
xHandlerBase.parse()] message=[#exported Error while
SAX parsing :3:-1 : org.xml
.sax.SAXParseException: The content beginning "< " is
not legal markup. Perhaps
the " " (&#20;) character should be a letter.] [See

I wonder if there is something wrong in how I am
invoking the interface. Here is the code:



System.out.println("\n\n\nSubmitted Predicate:
"+submitPredicate+"\n\n\n");

this.con.subscribe("<key
oid='"+this.type+"#"+this.version+"'
queryType='XPATH'>"+
           submitPredicate+"</key>", "<qos/>"); 


If it works for you then I must be doing something
wrong. Any ideas would be greatly appreciated.

Many Thanks,
Vaughn
