Re: SerializationException: Why with default Constructor -yes! implements Serializable- yes!
Hey, That's weird tho. Serializable and IsSerializable should both work... If Serializable does not work and IsSerializable does, you still might have a problem in that your serialization policy file, which is created at compile time, might not be getting generated correctly. When you use IsSerializable, the policy file is not consulted. Like I said, your code above works on my machine. Did you test using Serializable and recompiling? -Lyden On Jan 23, 11:21 pm, Shawn Brown wrote: > Hi, > > Why do I get "SerializationException: Type 'IdKeyHolder' was not > included in the set of types which can be serialized by this > SerializationPolicy or its Class object could not be loaded.

Re: SerializationException: Why with default Constructor -yes! implements Serializable- yes!
Hey, Your code looks good. Just to be sure, I created a sample project, and tested it. It works. So...something must be out of sync with your build.

Re: GWT + GILEAD + AXIS2 POJO PROBLEM
Hey, Probably a dumb question, but why do you need to use Axis2? I don't have any experience with it, but I built a GWT app that uses Gilead to deal with Hibernate/GWT serialization issues and was able to serialize my POJOs just fine using GWTs built in RPC mechanism. -Lyden On Jan 19, 2:56 pm, bond wrote: > Hi, > I've a project in witch I'm using Gwt 2.1.1 with Gilead 1.3.3, > Hibernate 3.3 and Axi2. > I created a web service that returns gilead pojo object of domain.

Re: GWT Connection to DB
Hey Again, GWT is client side only. There are no GWT widget that have built in server side functionality. Check out Apache Struts, Apache Wicket, and Apache Click. Here's a great resource for comparing web frameworks.

Re: GWT Connection to DB
Hey, You can use GWT RPC to handle server side logic like connecting to and interacting with a database. Be warned, if you choose to use Hibernate as an ORM, there is a steep learning curve. Hibernate may drive you crazy in the beginning, but once you understand all the unintuitive nuances, it rocks. Still GWT is not immediately well suited to work with Hibernate. Since everything on the client side of a GWT application is compiled into JavaScript, there are serialization problems when sending Hibernate objects to the client side. If you want to use Hibernate, I suggest also using Gilead to solve this problems. However, again since the client side is all compiled into JavaScript, no matter what you do, you will not be able to invoke any Hibernate related functionality on the client side. Remember, you can only reference classes on the client side that are implemented in GWT's JRE Emulation Reference: http://code.google.com/webtoolkit/doc/latest/RefJreEmulation.html You're in for a very long haul if you choose to use Hibernate. It's very sophisticated, but you might want to start out with a simpler setup such as using JSON / PHP / MySQL. Instead of using GWT RPC, just make direct Asynchronous HTTP requests for server side PHP using GWT's RequestBuilder object. Your PHP files will connect to and interact with the database. PHP has numerous built in functions for interacting with a MySQL database. Hope that helps! -Lyden On Jan 19, 1:38 am, Saurav Sarkar wrote: > Hi All, > > I am new to GWT.I installed the google plug-in for Eclipse and also > the Window builder. > > Now i want my application to connect to Database.Is there any GWT form > widget kind of thing which will automatically take care of my form > submissions to the database.Is something available in the Window > Builder also ? > > Or else what is the best practice being used in GWT code while > connecting to DB ?..I even had a look at the GWT-Hibernate libraries. > > Appreciate your response. > > Thanks and Regards, > Saurav -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Deployment: Choosing a Servlet Container and a Comet Framework
Hi all, I'm in the final stages of developing business management software for the company I work for. My project uses GWT 2.0 (might upgrade to 2.1), Hibernate 3.6, MySQL 5.1.46, and Gilead for GWT/Hibernate Serialization. Now it's time for me to start thinking about deployment, and I was hoping to solicit some advice on which Servlet Container to use. I don't have any experience with setting up and configuring a servlet container. Also I will not be using App Engine. Their website and this app will reside on GoDaddy's servers. I'm under a time crunch, but I'm also still considering replacing some client/server polling with a Comet (Server/Push) framework. Any advice on which framework to use would be most appreciated. Debating between: 1. gwteventservice 2. gwt-comet 3. gwt-comet-streamhub 4. rocket-gwt Lastly this is probably a very stupid question, but is there a way to package my app up along with the servlet container from GWT's embedded Jetty Server, and just host that container rather than go through the process of setting up and configuring a container like Tomcat? I'm guessing there are a number of reasons why, even if I could, I wouldn't want to do this... All in all, whichever container is the quickest and easiest to setup and configure for a beginner is going to be my choice.

Re: Reflection: Get Variable Name
Thanks again for the reply. I was planning to send the generated query to a PHP file on the server that connects to a MySQL database and executes the query, but point taken about the security hole. So how would I go about doing this then? Can I just make regular Java classes in the server package of my GWT project and then use RPC to send my DTOs across the wire to those classes where I can use Reflection to analyze the DTOs and build queries from them? Then I guess I would use JDBC to execute the query... Also, will I need to setup a servlet container like Tomcat on the server?

Re: Database and GWT
You have a couple of options: 1. Hibernate (or some other ORM tool) 2. JDBC 3. PHP and JSON Be prepared, the Hibernate learning curve is substantial. If you use Eclipse, you will need to install a slew of plugins for integrating Hibernate and whichever build tool you pefer, (Maven, Ant, etc.).

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.

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.
