hello all,<br>
<br>
I am a newbi on Drools and started my test work with a modified exapmle<br>
included in drools v4.0.7.The compiled drl from a very simple modified xls<br>
file is like the follwing :<br>
<br>
<br>
----------------------code-----------------------<br>
package org.drools.examples.decisiontable;<br>
#generated from Decision Table<br>
import org.apache.commons.lang.time.DateUtils;<br>
import java.util.Date;<br>
#From row number: 11<br>
rule "Pricing bracket_11"<br>
<br>
when<br>
DateUtils.SEMI_MONTH==1001<br></blockquote><div><br>This looks very wrong. The result of compiling a correct decision table should look like<br> SomeFactName( someFieldName == 1001)<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
then<br>
policy.setBasePrice(9999999);<br></blockquote><div><br>Where does the variable "policy" come from? It isn't bound to anything.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
end<br>
-------------------------code---------------------<br>
<br>
but I got an exception stack when trying to addPackage after compile :<br>
<br>

yes,I was trying to test the usage of org.apache.commons.lang.time.DateUtils<br>
inside a xls file,but it seemed something went wrong.</blockquote><div> </div><div>Spreadsheets over xls are not a convenient vehicle for testing conditional expressions or rule patterns in general. Write some DRL rules for this purpose.<br>
<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Can someone tell me<br>
what caused the exception?</blockquote><div><br>Syntax errors. Make sure to read the documentation on spreadsheets; how to define a Fact type for a conditional element (a "pattern") and how to add constraints to it.<br>
<br>-W<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> thanks a lot<br>
