Re: [xmlblaster] Errors when testing C-API

[Vaughn Combs <vaughn_combs at yahoo.com>]

I wonder if either of you have any comments on this
one. I posted this one almost 2 weeks ago but havent
heard any responses:



I notice that, for my added metadata :

<xmlBlaster>
 <key oid='Pubber'>
 
<metadata><baseObject><InfoObjectType><Name>mil.af.rl.jbi.training.basic</Nam
><MajorVersion>1</MajorVersion><MinorVersion>0</MinorVersion></InfoObjectType><
baseObject><BasicTemporal><beginning_date_time_group><day>11</day><hour_time>21
/hour_time><minute_time>23</minute_time><time_zone>Z</time_zone><month_name>Jun
</month_name><year>2001</year></beginning_date_time_group><ending_date_time_gro
p><day>12</day><hour_time>06</hour_time><minute_time>13</minute_time><time_zone
Z</time_zone><month_name>June</month_name><year>2001</year></ending_date_time_g
oup></BasicTemporal></metadata>
 </key>
<content size='2'>
Hi
</content>
 <qos>
 
<sender>/node/xmlBlaster_192_122_1_201_3412/client/combsv/-46</sender>
  <subscribe
id='__subId:xmlBlaster_192_122_1_201_3412-XPATH1112448315531000000
/>
  <rcvTimestamp nanos='1112448326390000000'/>
  <queue index='0' size='1'/>
  <isUpdate/>
 </qos>
</xmlBlaster>


 
I have expected results for the following predicate:
 


/xmlBlaster/key[metadata/BasicTemporal/beginning_date_time_group/hour_time>=21
]

 

but for:


/xmlBlaster/key[metadata/BasicTemporal/beginning_date_time_group/hour_time<22]


I get the following exception upon submission of the
subscription:


org.infospherics.commonAPI.impl.exception.PlatformFailureException:
XmlBlasterException errorCode=[resource.configuration]
serverSideException=false
location=[SaxHandlerBase.parse()] message=[#exported
Error while SAX parsing :1:-1 :
org.xml.sax.SAXParseException: The content beginning
"<2" is not legal markup. Perhaps the "2" ( )
character should be a letter.] [See URL
http://www.xmlblaster.org/xmlBlaster/doc/requirements/admin.errorcodes.listing.html#resource.configuration]

Any ideas or suggestions?

Many Thanks,

Vaughn
