Hi. Me again. I was wondering how could i code my jsp page when i want the following page.
I have the main contract page where you can see the certain property that is in that contract. Contract and Property are connected by contractproperty which contains both contractID and propertyID.
I need to make form to add a new property to the contract. And i need the contractId to be automatically selected when i start to insert the new property to the contract.
It seems simple to do it with just the JSP page that access the database directly, but when i use java classes to access the database then how should i write the query to allow me to do the following. Currently when i begin to add the new contract i have to select the contract ID manually. So how can i do it automatically.(I cut out not so important parts of the code)
Well this is the form to insert the new property to the contract.
---code--
<h:outputText value="PropertyID:"/>
<h:selectOneMenu id="propertyID" value="#{contractProperty.contractProperty.propertyID}" title="PropertyID" required="true" requiredMessage="The propertyID field is required." >
<f:selectItems value="#{property.propertyItemsAvailableSelectOne}"/>
</h:selectOneMenu>
<h:outputText value="ContractID:"/>
<h:selectOneMenu id="contractID" value="#{contractProperty.contractProperty.contractID}" title="ContractID" required="true" requiredMessage="The contractID field is required." >
<f:selectItems value="#{contract.contractItemsAvailableSelectOne}"/>
</h:selectOneMenu>
<br />
<h:commandLink action="#{contractProperty.create}" value="Create"/>
<br />
--code---This is the contractproperty class file.

Since the code is netbeans generated i'm little behind of understanding it, but i'm doing my best to chew trought it...
