Hi all!!
Im having some problems with calling functions one from another in .drl
Here is some code snippet:
#created on: 2007.04.03
*
package* hr.combis.unimsg.ruleengine.rules.message
#list any import classes here.
*
import* javax.mail.internet.MimeMessage;
*
import* javax.mail.internet.InternetAddress;
*
import* javax.mail.Message;
*
import* javax.mail.Header;
*
import* javax.mail.Multipart;
*
import* javax.mail.Part;
*
import* java.util.Enumeration;
*
import* java.lang.String;
*
import* java.lang.Object;
*
import* java.lang.Integer;
#declare any global variables here
#global IMessageService messageService;
*
rule* "Initial rule"
*when
*
#conditions
msg : MimeMessage( )
*then*
#actions
drools.setFocus("Content group");
*
end
*
*
rule* "Header parsing rule"
*agenda-group* "Header group"
*when
*
#conditions
msg : MimeMessage( )
*then*
#actions
*if* (msg.getContent() != *null* && msg.getAllHeaders() != *null*){
System.out.println("TODO: header processing");
}
*
end
*
*
rule* "Content parsing rule"
*agenda-group* "Content group"
*when
*
#conditions
msg : MimeMessage( )
*then*
#actions
*if* (msg.getContent() != *null*){
*if* (msg.getContent() *instanceof* Multipart){
System.out.println("mail je multipart");
Object body = msg.getContent();
processMultipart((Multipart) body);
}*else*{
System.out.println("mail je singlepart");
singlePart(msg);
}
}
drools.setFocus("Header group");
*
end
*
*
function* *void* singlePart(Part p) {
String fileName = p.getFileName( );
String disposition = p.getDisposition( );
String contentType = p.getContentType( );
*if* (contentType.toLowerCase( ).startsWith("multipart/")) {
System.out.println("Part ima svoje partove");
ProcessMultipart.processMultipart((Multipart) p.getContent( ) );
}
p.writeTo(System.out);
}
*
function* *void* processMultipart(Multipart mp){
System.out.println("procesiram multipart");
*for* (*int* i = 0; i < mp.getCount(); i++){
Part part = mp.getBodyPart(i);
System.out.println("Procesiram part: " + i);
SinglePart.singlePart(part);
}
}
When i assert in working memory multipart message , the first is being
called processMultipart() method, which then calls singlePart() method for
each part and that works just fine. But, when singlePart needs to call
processMultipart() again (thats just the way javamail api works), everything
crashes with no specific explanation. Here is the part of log:
ERROR 07 04 2007 12:36:05,031 - Bad error

Please, help. Thnx

Can u be more specific?
As u can see, there are no imports for processMulipart() and singlePart()
methods.
In order to call one drl function in another u need to access it through
static call from a "class" that has very same name. I've got that tip on
#drools irc.
I'm using drools 3.0.6, and pretty much a newbie in drools, perhaps you have
a better solution?

I believe you failed to import SinglePart.

Ah! I was unaware of and confused by that "class" weirdness.
I think I
am too ignorant to help you. Please ignore me. Sorry.
