I'm using a knowledgeagent to point out a changeset XML which contains the<br>
following DTABLE:<br><br>
...<br>
<resource source='file:/../templatetest.xls' type='DTABLE' /><br>
...<br><br>
when I compile I get the following error:<br><br>
Unable to Analyse Expression request == "/":<br>
[Error: unable to resolve method using strict-mode:<br>
ultra.Default.ultra.MYHTTPD.request()]<br>
[Near : {... request == "/" ....}]<br>
^<br>
[Line: 7, Column: 10] : [Rule name='print the incoming query_9']<br><br>
The weird this is that MYHTTPD class is a javabean and contains getRequest<br>
and setRequest methods.<br>
notice that it tries a no getter method<br>
ultra.Default.ultra.MYHTTPD.request().<br>
If I do the same logic from a normal DRL rules file it works fine.<br>
MYHTTPD is generated so I cannot past the source here, but it's correct and<br>
as I mentioned working in DRL files.<br><br>
this is how the XSL file looks like:<br><br>
RuleSet A rules test<br>
Import ultra.Default.ultra.MYHTTPD<br><br>
RuleTable print the incoming query<br>
CONDITION ACTION<br>
MYHTTPD<br>
request System.out.println($param);<br>
Matcher Logger<br>
/ "webserver root"<br><br>
Anybody who knows what this is about?<br><br>
Thanks // Olle<br><span class="HOEnZb"><font color="#888888"><br><br><br><br><br><br>
