I’ve been following the e-commerce tutorial located here: http://netbeans.org/kb/docs/javaee/ecommerce/intro.html

Code repo of project here.

I have ran into a few problems that I believe are related:

1: Trying to view the customers’ orders on the Admin page results in: 

**WARNING**: EJB5184:A system exception occurred during an invocation on EJB OrderManager, method: public java.util.Map session.OrderManager.getOrderDetails(int)

**WARNING**: javax.ejb.EJBTransactionRolledbackException

**WARNING**: EJB5184:A system exception occurred during an invocation on EJB OrderedproductFacade, method: public java.util.List session.OrderedproductFacade.findByOrderId(java.lang.Object)

**WARNING**: javax.ejb.TransactionRolledbackLocalException: Exception thrown from bean
Caused by: java.lang.IllegalArgumentException: You have attempted to set a parameter value using a name of customerOrderId that does not exist in the query string SELECT o FROM Orderedproduct o WHERE o.orderedproductPK.custOrderid = :custOrderid.

2: Trying to view details for a particular order in the admin page results in:

WARNING: StandardWrapperValve[AdminServlet]: PWC1406: Servlet.service() for servlet AdminServlet threw exception
Caused by: java.lang.IllegalArgumentException: You have attempted to set a parameter value using a name of customerOrderId that does not exist in the query string SELECT o FROM Orderedproduct o WHERE o.orderedproductPK.custOrderid = :custOrderid.

Both problems have the ‘findByOrderId’ method in common and I am at a loss as to what is wrong with it.

The offending method is located in the following directory: src/jsf_crud/src/java/session/OrderedProductFacade.java

(I would link it as a hyperlink but spam prevention measures prevent me)

Not sure what the best course of action is, any recommendations?

    Your query needs a parameter called “custOrderid” and not “customerOrderId”

    Either change the query or change the called parameter.

    The query in the OrderedProduct class uses “customerOrderId”
