Hi Maneesh,

Following are the mvp frameworks I found from here

mvp4g
gwt-platform
gwt-presenter
gwt-dispatch etc

My question here is if I choose mvp4g, will it be compatible with SmartGWT components?

Hello Ranchers,

In my new project client has requested to use GWT/SmartGWT for developing presentation tier. (Note: Screens are not much complex)
I am aware about the MVP Pattern but I need to decide which flavor of the MVP pattern I should use which meets following criteria.

1. I should be able to integrate/use SmartGWT components seamlessly with the MVP framework.
2. It would be great if framework provides me flexibility to support UI to be displayed on Mobile or iPad sort of devices.

Any guidance on this would be highly appreciated.

Thanks!!
Bhavesh

IMO,

Spring and EJB 3.0 are not alternative to each other. We can fine tune our application by taking advantage of both the technologies.

For e.g; Server components can be written in EJB 3.0 and other tiers can be developed elegantly using Spring framework.

It is completely depend on the architectural need of the particular application and based on that analysis only we can make decision.

Should not be biased on any of these technologies.

Hello Ranchers,

I came across a scenario where I have to user Hibernate hbm files along with Annotated EJB3.0 Entity Beans where I am facing an issue while retrieving entity configured as hbm file.

Issue : The identity value of the entity is coming with default '0' value set where actual value of id should be primary key value stored in database.

For understanding it well please refer following code:

Annotated abstract Entity:

@MappedSuperclass public abstract class BaseEntity implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "id") private long id; @Version @Column(name = "VERSION", nullable=false) private int version = 0; public BaseEntity() { super(); } public long getId() { return this.id; } public void setId(long id) { this.id = id; } public int getVersion() { return version; } public void setVersion(int version) { this.version = version; } }

Entity Configured via hbm file :

/** * @author bhaveshsh * */ public class Device extends BaseEntity { private String description; private DeviceType deviceType; private Set<User> deviceUsers; public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public DeviceType getDeviceType() { return deviceType; } public void setDeviceType(DeviceType deviceType) { this.deviceType = deviceType; } public Set<User> getDeviceUsers() { return deviceUsers; } public void setDeviceUsers(Set<User> deviceUsers) { this.deviceUsers = deviceUsers; } }

Hbm Configuration file : "device.hbm.xml"

<hibernate-mapping> <class name="com.sample.ejb.entities.Device" table="device_master" dynamic-update="true"> <id column="ID" type="long"> <generator class="native" /> </id> <property name="description" type="java.lang.String" column="DEVICE_DESCRIPTION" /> <property name="deviceType" not-null="true" column="DEVICE_TYPE"> <type name="com.sample.ejb.entities.GenericEnumUserType"> <param name="enumClass">com.sample.ejb.entities.DeviceType</param> </type> </property> <set name="deviceUsers" lazy="true" inverse="true" table="user_device_map"> <key column="DEVICE_ID"></key> <many-to-many class="com.sample.ejb.entities.User" column="USER_ID"></many-to-many> </set> </class> </hibernate-mapping>

I am using stateless session beans for implementation of service and dao layers.

following is the code through which I am trying to fetch an instance of Device.

Query query = entityManager.createQuery("from Device as device where device.id = :deviceId"); query.setParameter("deviceId", id); Device device = (Device) query.getSingleResult();

Problem: Code mentioned above works fine but the id value doesn't populate properly and come up as default '0' value.
Can anybody figure it out why it is happening?

Before your last post I just got your point of using ClientLoginModule which is enough as far as actual authentication happens at server side where I have used DataBaseServerLoginModule.

I am just done with implementation with ClientLoginModule and changed configuration file with just following,

client-auth{ org.jboss.security.ClientLoginModule required ; };

Now everything (authorization and authentication) is working smoothly with my EJB 3.0 modules.

You really rock Jai, Thanks for your help and Happy Independence day in advance .

Thanks Jai for response,

Are you sure you want to use the DataBaseServerLoginModule on the client side (and not on server side)?

If I do not use this module then what should be the best practice for client side security implementation. My application is going to be a standalone swing application.

That login module requires not just the transaction manager but also the datasource to be accessible on the client side

I have given data source information in config file as below
SampleAuth { org.jboss.security.auth.spi.DatabaseServerLoginModule required debug=true dsJndiName="java:/RoviDS" principalsQuery="select um.password from user_master um where username=?" rolesQuery="select rm.ROLE_NAME, 'Roles' from role_master rm, user_role_map urm where rm.id=urm.role_id and urm.user_id=?" ; };

I have read somewhere that transaction manager is not allowed to be used outside the container then how would I achieve this?

I don't understand why it requires transaction while executing select queries on database.
It seems I have to give up on this, no progress since last 3 days

Hello friends,

This is first time I am implementing JAAS mechanism in my EJB3.0 + Jboss 5.1.0 applicaiton.
I really appreciate if anybody can guide me to resolve following exception which am getting while performing authentication through standalone Java application.

Note: One strange thing I have noticed it that I am not seeing java:/jaas/SampleAuth anywhere in JBoss Console log

Please help me where the problem is.

Gone through several resources over the net but not finding solution to this issue.

Am also facing the same exception with the similar configuration of security as Chris has done

Has anybody resolved or came across this exception?

Did anybody find anything on it?

Hi all,

I am implementing secured web service for the first time using rampart module of Apache Axis2.

Please help me to investigate this issue. where did I made the mistake or missed something ?

welcome to javaranch avneesh.

I would recommend O'reilly "Java Web Services" by David A. Chappell & Tylor Jewell.
Fundamentals explained in here very easy to understand (brief and concise).

Once you understand fundamentals and building blocks of Web services you can go for further advanced materials.

Do don't want to go by that stratagy because I want to use same set of domain entities across the application (for both client and server) because it will reduce the maintenance because we are dealing with single set of entities.
