I am trying to create rules from the database so creating a list which have rulename,lhs and rhs. Also I am trying to create rules using two pojo object but some how i am getting exception in rule syntax. Below is the code snippet.

for (int i = 0; i < 5; i++) {

dbRules = new DbRules(i, "Rule Name - " + i, "  $mdmContractHeader : MdmContractHeader( $s : supplierName )  $contractHeader1 : ContractHeader ( supplierName == $s ) "

+ " &&  contractHeader:ContractHeader(supplierId >= 100)",

"System.out.print(\"Test, Drools rule - " + i

+ ".! \"); System.out.println(contractHeader.getSupplierName());");

list.add(dbRules);

}

and Below is the error in console.
