To deal with updates of existing data, where for instance collection is involved, the hibernate merge operation comes in handy. I did not get into Gilead because I could not get the Gilead dynamic proxy stuff to work out, and in the end, I didn't need it anyway. -Dave --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT RPC Hibernate - again and again
The latest I guess (depending on the version of GWT you use???). There is a forum (there was at least one for h4gwt) where the author can help you... You should be carefull though which version of the gwt-servlet.jar you use. I spend a whole day trying to figure out why an older version of this jar refused to serialize my objects after an upgrade...

Re: GWT RPC Hibernate - again and again
Damn .. you are the man hat solved my problem. I started with the StockWatcher application, and then added my Hibernate POJO's and DAO;s. However, I had the DAO's under the client directory, when I managed to move those DAO's to the /server section, then it worked. I am now able to get my data from the database, and it did show up on my UI. So ... there are a number of issues I am working through ... but I've gotten past this log jam.

Re: GWT RPC Hibernate - again and again
fyi: I have posted a feature request into Hibernates Jira asking for a new entity mode be added. Current Hibernate supports the current entity modes. XML POJO MAP This means that entities can be retrieved and updated again in these formats. Now, if we could just add JSON to this list. Having JSON would mean you would be able to get an object graph out of hibernate as JSON, send it down using GWT, update it and send it back to Hibernate. This would solve many, many issues. I think it requires a new Tuplizer implementation for Hibernate. I meight even have a go at this when I have time. What do you all think? Here's the Jira issue.

Re: GWT RPC Hibernate - again and again
Hello Thomas, Do you have Hibernate working with annotations? If you don't have an cfg.xml file set up and mapping files, Hibernate will not work. You are also attempting to call spring classes inside of GWT which will not work. I created a Domain package that serves as the in-between for your shared client/server data classes that are passed via RPC. In your .gwt.xml file for your project you need to add source path=domain / to the file to tell GWT that it can use those classes as well as the client package. Now you have the problem with serializing Hibernate object from client/ server. Gilead is what I am using, there are other ways to do this but Bruno did a great job creating the lib. Basically the Hibernate objects that are generated are too complex to be converted to js objects so Gilead takes the nasty work out of the conversion. Take a look at which core java libraries can be converted to js by GWT. Anything else will fail for the most part so don't try to include it in your client code. The server package will allow you to do anything you want java-wise.

GWT RPC Hibernate - again and again
I am going to keep asking and keep bugging and jumping up and down until I get an answer that can help me. I have the book Pro Web 2.0 Application Development with GWT and Chapter 6 is about saving work with Hibernate to the database ... too bad it expects a hibernate.cfg.xml file and Object.hbm.xml files, we have neither. We have Spring 2.5.6 Beans and use Hibernate-Annotations. The DAO's and POJO's all work, that is something we did ahead of time. After research in this group, and on Google in general, I have found that I should look at Gilead. So, I downloaded the latest jars and the latest sample (using GWT 1.6) and sure enough, AGAIN, the sample uses hibernate.cfg.xml and Object.hbm.xml files Maybe I just need to tweak that sample and get rid of the hibernate.cfg.xml and hbm.xml files ... Maybe I should just change them use use HIbernate-Annotations? I'll test this out and see if it works. If anyone can let me know if this will work, or if there is a better way, that would be great.
