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:
