hi, we are using Drools 4.0.7
and have a rule which uses a Hibernate entity (SaleEventItem) and its related
entity (Inventory). Some times, the SaleEventItem passed as the fact has the
Inventory lazy loaded and hence its type is the Hibernate proxy -
Inventory_$$_javassist_93. In this case, the rule runs fine.
But at times, the SaleEventItem which is passed has the Inventory attribute set
explicitly and hence its type is Inventory itself. When the rule fires in this
case, it tries to assign the Inventory into Inventory_$$_javassist_93 which
causes this ClassCastException. java.lang.ClassCastException: com.crom.data.pojo.Inventory
incompatible with
com.crom.data.pojo.Inventory_$$_javassist_93

How do we prevent this? Is it possible to somehow enforce that the type of the variable
in the rule should be Inventory and not Inventory_$$_javassist_93?
The rule is as follows.
dialect "java"
when
$sale:SaleEventItem(inventory != null,
$leaseInfo:inventory.leaseInformation != null,
$saleEventPrize:inventory.leaseInformation.residualPayAmount != null)
then
$sale.setStartPrice((Double)$sale.getInventory().getLeaseInformation().getResidualPayAmount());
Thanks,Sobha

Hi folks,
we have exposed rules services using a web-service - we use XFire/CXF for our
web-services. Server is Weblogic 10.0. The web-services worked in 5.0CR1, after we
upgraded to 5.0, we run into classpath issues between XFire/CXF, Antlr and Weblogic.
Tried quite a few solutions on google, but have had no luck.
Has anyone had similar issues? Is anyone using a similar framework?
