[rules-users] The buss pass example of inference results in compilation errors, how to solve these?

Hi, In the Drools documentation is "the buss pass" example of how to use inference. rule "Infer Adult" when $p : Person( age >= 18 ) then insert( new IsAdult( $p ) ) end However, when I try this myself I get compilation errors on IsAdult and a missing ";" after the insert statement. (I am using the Drools plugin in Eclipse) Here is an example of my own what has the same issue: //list any import classes here. import com.example.vdc.VdcLandingPage; import com.invoicestore.domain.Debtor; //declare any global variables here global VdcLandingPage UI; rule "Infer bad debtor" when $debtor : Debtor( isBadDebtor() == true ) then insert( new IsBadDebtor( $debtor ) ); end BuildError: Unable to Analyse Expression drools.insert( new IsBadDebtor( $debtor ) );: [Error: Failed to compileShared: 1 compilation error(s): - (1,16) could not resolve class: IsBadDebtor] [Near : {... drools.insert( new IsBadDebtor( $debtor ) ); ....}] ^ [Line: 23, Column: 0] I have studied the Drools documentation and cannot find anything what might lead to a solution. I have tried to set the dialect to "mvel" but that is not solving the problem. Any suggestions how to solve this? -- View this message in context: http://drools.46999.n3.nabble.com/The-buss-pass-example-of-inference-resu...
