Re: GWT Hibernate Project Structure
Thanks Yau, That would be great. Any info you could give me on how you setup your project would be great. Are you using Eclipse? Also, is it the correct procedure to place your Hibernate jars and dependencies in the war/WEB- INF/lib directory and then add them to the build path? Thanks for your help!

Re: GWT Hibernate Project Structure
I haven't tried Maven but I'm using GWT + Hibernate3 + Gilead. It's very difficult to setup Gilead as the example provided by GWT is very very outdated and no longer compatible. It took me 2 days to figure out how to set it up with the correct jar, import path and syntax. If you're still interested in Gilead, I can provide some info.

Re: GWT Hibernate Project Structure
Thanks Gabriel, I've read differing opinions on whether client and server code should be split into two projects. At this point, I really don't care which about which approach I use as long as I get something up and running that is error free. Could someone explain to me a specific procedure for setting up a GWT + Maven2 + Hibernate3 project in Eclipse? For instance, if I were to use only one project, do I create a new GWT project with the GWT Eclipse plugin and then modify its directory structure to conform to Maven's standard directory layout? Or, do I create a Maven project with the m2eclipse plugin and then enable GWT in that project? Frankly, I'm not sure where the best place to start is. This is my first project using multiple technologies together, and although I feel like I understand a good deal of how these technologies work individually, I don't understand how to make them work together. Any help would be most appreciated.

Re: GWT Hibernate Project Structure
Hi, Do you have a reason for splitting the application into two projects? If not, there is nothing preventing you from using a single project for both client and server. If you do need to have two projects, you can use two (server and client) or three (server, client and common) modules under one maven project and define the dependencies among them (if you hadn't used Maven, you could have used the IDE to define the dependencies between projects). I suggest you read the documentation here: http://code.google.com/eclipse/docs/users_guide.html On May 21, 6:20 am, Maurice Nee wrote: > Hi, > > This is my first ever forum post.

GWT Hibernate Project Structure
Hi, This is my first ever forum post. I really need some help with understanding how to setup a GWT 2.0 Hibernate3 project. I understand the GWT RPC mechanism and the problems with serializing Hibernate POJOs. I would prefer to use DTO's rather than Gilead or Dozer. So far, I have a Hibernate Project built with Maven2 in Eclipse using the m2eclipse plugin and the HibernateTools plugin for Eclipse. I also have a GWT 2.0 project built with the GWT plugin for Eclipse. I'm using MySql as the RDBMS. What I don't understand is how to setup, configure, and deploy the two projects in such a way that they can communicate with each other. Let's say with the above setup, I'm trying to persist a Person object that has only an id, and a name as fields. In my Hibernate project, I would create a Person.hbm.xml Hibernate mapping document, and then generate the corresponding Hibernate Java POJO and MySql table. Then, in my GWT project, I would create a serializable PersonDTO.java class that can be sent 'across the wire' to and from the server via GWT RPC. Then, for simplicity's sake, let's say that in the client package of my GWT project I create a CreatePersonService.java interface and a CreatePersonServiceAsync.java interface with one method, void createPerson(). I would then need a CreatePersonServiceImp.java class on the server side that implements createPerson(). Fine, but here's where I get confused. If the createPersonServiceImp.java class is going to transform a PersonDTO.java class into its Hibernate POJO equivalent, then it needs to utilize classes from both my GWT Eclipse project and Hibernate Eclipse project. So which project do I put it in? It needs to have access to GWT classes like PersonDTO, AsyncCallback and other RPC classes. It also needs access to Hibernate classes like SessionFactory, Transaction, etc. So it needs to have access to my GWT jars and Hibernate jars which are in two separate projects. How do do I link them so that CreatePersonServiceImp.java has access to all the libraries it needs. Finally, how do I correctly merge both of these projects into one WAR file for deploying onto a server? Or am I way off track? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
