[rules-users] NoSuchMethodError

[Hehl, Thomas]

OK, I upgraded to 4.0.2 and here is the updated error:

 

java.lang.NoSuchMethodError:

I have found this function in the file core-3.2.3.v_686_R32x.jar in the
drools/lib directory for 4.2.

 

One of the things that has happened recently is that I have upgraded from
3.2 to 3.3.1. I thought this might be part of the problem, but I looked at
the core jar for 3.3.1 and it has the same method.

 

The thing that puzzles me is that I'm not including the core file in my
distribution, but if that's the problem, why am I not getting a
ClassNotFoundException?

 

Thanks.

I am running 4.01 and I started get this exception on a new piece of code:

It is blowing up on this line of code:

 

builder.addPackageFromDrl( new StringReader(drl) );

 

Which is the drl created from the spreadsheet compiler on the decision
table.

 

This rules class has been tested thoroughly under junit. It wasn't until I
deployed the library into my webapp that this issue turned up.

 

Does anyone have any idea what I should be doing next?

 

Thanks.
