Re: What's the best/easiest way of doing server-side persistence with GWT?
Hi, could you release your GWT mysql project somewhere on the web. Would be very helpful for me see real complete project of GWT and database integration. I have to say, that in my case we plan to use stored procedures only on the db side for access data. thx. kensai On 21 kvě, 16:50, Robnauticus- wrote: > Hello, > I have completed a GWT / Hibernate / gilead / mysql project.

SmartGWT and Database integration example
Hello there, could someone provide me with complete eclipse project where schould be used rather SmartGWT then GWT gui components integrated with any sql type database engine? This will really help me. Thank you. Kensai -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT or SmartGWT and Oracle - Stored procedures
Well, I went trough many tutorials and howtos on internet. The one was amazing and it solved all my needs. DataSource definition is in XML and I can execute CRUD operations using storedc procedures on the database side. I am talking about project SmartClient. One can define DataSource using this way: call spUpdateWSSWatchSources($values._watchID, $wssSourceIDs) This is very easy to write, but licence for one developer could be very expensive, I think about almost 2000 dolars for the Power version which supports the SQL templating, exactly putting into the XML definiton of the datasource element I can forget buying this for this project, maybe in the future. But what next? How to proceed with SmartGWT and SQL engine? Current answer is using EoD SQL as ORM subsystem. There are some bad things about loosing lazzy loading feature, etc., but in my case it seems to be the best way now as you can see at: http://lemnik.wordpress.com/2009/09/18/eod-sql-applied-%E2%80%93-part-5-5-gwt-applications/ Any your suggestion would be helpful.

Re: GWT, servlet, JSP and datastore
Tristan maybe you could help me, do you have any completed Eclipse project with grid connected to database? I would thank you if you could provide me such thing to learn more. I am on dead point. We will use only stored procedures for communication with database and I am not able to find any rich subject related to this over net. Our application will run finally on intranet, so in our case there is no possibility of using online google app engine, altough I already tried to use it and it worked well.

GWT or SmartGWT and Oracle - Stored procedures
Hello, I am new to GWT at all. My approach is to have an editable grid on the client side and one or more tables on the database side (Oracle in my case). Could someone post really working project with all files which supports all 4 standard operations (select, insert, update, delete)? In my case I want to do all these operations using stored procedures to avoid SQL injection attacks. Any external link or pure sample will help. I was not able to find any complete project which is I think best to learn it as complex logic. Thank you very much.

Re: GWT, servlet, JSP and datastore
Hi Laurent, I am also new to GWT, also fascinated :-). I also already went trough samples and tutorials and well stopped at the point how to bind components to, in my case, database table in Oracle database. I don't know what do you mean exactly by "Google datastore" but I think you mean the Datastore class in GWT framework. Even GWT is very good for creating nice GUI on the client side, it's object-relational mapping is still in incubation period and you following options how to proceed: 1.) You need to manually write the functions which manipulate with data on the server side and call it via AJAX (JavaScript) from the client side when necessary. 2.) Look at EoD SQL project at http://eodsql.sourceforge.net/ this library may help you, there are also tutorials how to use it together with GWT 3.) This is the easiest, free for trial then payed, option. Use SmartGWT Professional or Enterprise. Take a look at it http://code.google.com/p/smartgwt/. It has integrated tomcat inside. In the SDK there are lot of examples and tutorials, but also something what you will find maybe really useful: Datasource generator - generate XML DS descriptional file, works with standard database engines, etc. Visual designer - you can create client layouts in visual way, in this tool you are also able to use for example Datagrid directly with Datasource you created in generator, and you have component directly interacting with any datasource. I found SmartGWT SDK best for learning, as standard GWT, you have access to all Java, XML files, but from Visual designer you also generate JSP file and can see what have you created. Hope I helped you. Also send me your experiences I you already found something better, different.
