[jboss-user] [JBoss Seam] - Stop the violence! How should we be separating our beans?
Our developers are getting ready to come to blows.
How should we be separating our session beans? Is the preferred method for application
design in seam to have 1 ejb for the Action Listener and another to contain the actual
business methods, refer to ex 1? Or should we just combine the 2 beans in to 1 refer to ex
2.
ex 1.
| @Stateful
| @Name("addressmanager")
| public class AddressManagerBean implements AddressManager {
|
| @In
| private Address address;
|
| //..some other business methods.
|
| public boolean allowAddressChange() {
| //perform some sort of rules check.
|
| return rulecheck.checkAddressRules();
| }
| }
|
|
| @Stateful
| @Name("addressmanageraction")
| public class AddressManagerActionBean implements AddressManagerAction {
|
| @In
| private Address address;
|
| @In
| private AddressManager addressManager;
|
| @In
| private FacesMessages facesMessages;
|
| //..some other business methods.
|
| public void checkifAllowAddressChange() {
| if ( ! addressManager.allowAddressChange()) {
| facesMessages.addToControl("FailedAddressChangeRuleCheck",
"The addrress can not be changed.");
| }
| }
| }
|
| //The pages.xml or .jpdl.xml file would contain the navigation rules.

ex 2.
| @Stateful
| @Name("addressmanager")
| public class AddressManagerBean implements AddressManager {
|
| @In
| private Address address;
|
| @In
| private FacesMessages facesMessages;
|
| //..some other business methods.
|
| public boolean checkifAllowAddressChange() {
|
| boolean allowAddressChange rulecheck.checkAddressRules(); //This could maybe be
replaced by Drools
|
|
| if ( ! allowAddressChange()) {
| facesMessages.addToControl("FailedAddressChangeRuleCheck",
"The addrress can not be changed.");
| }
|
| return allowAddressChange();
| }
| }
|
| // The pages.xml or .jpdl.xml file would contain the navigation rules.
