Re: GWT + MySQL
Hi Greg, Finally I found someone who has been working on MySQL in GWT. I am working on a project that involves both. But I am kind of stuck with the similar issue. Can send a sample example to better understanding of GWT and MySQL. I am using GWT-RPC.

Thanks Joe, It's just that I've had a very bad experience with Mochahost.

Just about any host. Nothing special needed for GWT. If you're using a Java backend, then you'll need a host that can support a war/ear deployment or get your own VPS.

Re: GWT + MySQL
Here's the important part of your bug: Exception while dispatching incoming RPC call com.google.gwt.user.client.rpc.SerializationException: Type 'com.mysql.jdbc.exceptions.jdbc4.CommunicationsException' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded Your code is trying to send a com.mysql.jdbc.exceptions.jdbc4.CommunicationsException via RPC, which it can NOT do. My guess is that your servlet code is throwing that exception, but that is just a guess. But step 1 is to check all your RPC routines, and make sure none of them have a throws clause.

Re: GWT + MySQL
I've used MySQL in just about every GWT app I've written, so it's quite possible to use it. Including during development running Jetty. 1: All JDBC calls MUST come from the server. The client code can NOT see any jar files, ever. 2: You can NOT reference com.mysql.jdbc.Driver, or any other package that comes from a jar file, in any class that will end up in the client. It doesn't matter if that code is only called from the server. Any class that imports anything from a jar file (or from any of the classes that aren't on the client use whitelist) MUST be in the server package. My guess is that you have one or more classes in *.shared that are importing com.mysql.jdbc.Driver. Move those classes to *.server, or move all the MySQL functionality out of them and into classes that are in *.server. Greg On Nov 30, 2:54 am, mgm wrote: > I am having the same issue..

Is the mysql driver jar file in the server's runtime classpath? It ought to be in your war file.

Re: GWT + MySQL
I doubt that your mySQL JDBC source code will correctly translate to JavaScript (You must have the source code to even start down this road). Even if it did, you probably won't have any of the supporting libraries on the client side. Instead, you use GWT's RPC mechanism to call routines on your server. Those routines will then send data to the client.

Hi there, I've spent numerous hours this week trying to get my existing GWT application to connect with an existing MySQL database with no luck. I've created my code to connect to the database using JDBC and is kept in the server package to ensure it remains as java code.

Re: GWT MySQL
Hi, try using the hibernate entity manager. I am also producing a web pages based on mysql. Remeber to disable the App Engine of the GWT project in eclipse and delete the all the jar file related with datanucleus in your buildpath. Datanucleus is not compatible with hibernate the application will consistenly complain that it cannot correctly configure the JDO datasource. etwa On Jan 13, 3:36 pm, ANDRES BRUN wrote: > Hello everybody > > Which is the better way for work with GWT and MySQL, jsp's, php's, > webservices or what?

Re: GWT MySQL
Thanks everybody for your answers and I hope take a good decision. I like PHP in the server because I think that is more speed than other technologies but I like JSP/Servlets too. The server is Linux (Debian or Ubuntu) and the DB is MySQL 5. Thank you again.

Re: GWT MySQL PHP
GWT can communicate over HTTP requests with any server side technology supporting HTTP. So your PHP app should provide a (maybe RESTful) interface, which can be called by Ajax request and uses either JSON or XML as data format. I don't know how you can tell PHP to that, but on the GWT site, you should use the RequestBuilder to create a HTTP request an than parse the result as JSON. Make sure your architecture is clean. GWT is for RIAs, so it should be designed, as it would be able to run without a server. HTTP requests are just for getting some raw data from the server, so you should care to have a very slim communication layer between client and server.

Re: GWT Mysql Error - java.net.InetAddress is a restricted class.
Short Answer : Just disable Google App Engine for your project, and things should start working. Its a setting in the Google Eclipse Plugin. Long Answer : GWT and Google App Engine (GAE) are two separate projects, and you don't have to use them together. If you enable GAE - you cannot use any other database. If you disable GAE and only use GWT - you can use whatever you want on the server side. Client side restrictions still apply. Many, many users have accidentally enabled GAE (or is it enabled by default?) and have faced this issue, so this isn't new. --Sri 2009/11/18 Muthukumaran Balan > Hi Sri, > > I am using Hibernate to access the database and used the example from > http://code.google.com/webtoolkit/articles/using_gwt_with_hibernate.html. > When i create a hibernate session from rpc servlet, it throws error > "INetAddress is a restricted class". :( > > Even i tried GiLead library, even in that when i tried to create a > hibernate session and set it to persistance manager it throws the same > error. :( > > regards, > Muthu > > On Nov 18, 12:25 pm, Sripathi Krishnan > wrote: > > If you are using Google App Engine, you cannot access databases even @ > > server side.

Hi Sri, I am using Hibernate to access the database and used the example from http://code.google.com/webtoolkit/articles/using_gwt_with_hibernate.html. When i create a hibernate session from rpc servlet, it throws error "INetAddress is a restricted class". :( Even i tried GiLead library, even in that when i tried to create a hibernate session and set it to persistance manager it throws the same error. :( regards, Muthu On Nov 18, 12:25 pm, Sripathi Krishnan wrote: > If you are using Google App Engine, you cannot access databases even @ > server side.

Re: GWT Mysql Error - java.net.InetAddress is a restricted class.
Thanks for the reply chris. The code for accessing the database is running on the server-side of the RPC[servlet]. Moreover, if mysql-jdbc-driver cant use these inetaddress class, then we cannot access the database even @ server side? is there anyother way or my configuration is wrong? thanks and regards, Muthu On Nov 18, 2:08 am, Chris Ramsdale wrote: > You may want to post this on the general App Engine forum, but the net net > is that certain APIs and classes are white listed (and subsequently black > listed) within App Engine. > > List of white listed JRE > classes:http://code.google.com/appengine/docs/java/jrewhitelist.html > > App Engine Group:http://groups.google.com/group/google-appengine > > On Tue, Nov 17, 2009 at 4:01 AM, Muthukumaran Balan wrote: > > > > > Hi All, > > > I am getting " java.net.InetAddress is a restricted class." error when > > trying to get a Hibernate Session for MySQL DB as below.

You may want to post this on the general App Engine forum, but the net net is that certain APIs and classes are white listed (and subsequently black listed) within App Engine.

Re: Java+GWT+MySQl probleme to load drivers
Quel est ton problème et surtout le rapport avec GWT ?
Tout ce qui est SQL est du coté serveur. GWT étant le front-end
excepté les RPC.

Java+GWT+MySQl probleme to load drivers
Hello
whene i test my connection with Mysql db using a main test class
(without the GWT client) it works fine, but when my impl class
call the connection class I get error to load drivers, I dont really
understand why, is there something that I should add to GWT ? my db
driver are set in classPath and whene I test the communication between
client and server in GWT with a simple helloword it works...I'am
stuck ...any idea whats going on ...
thanks
this is my connection class
public class MySqlConnection {
private static String url = db_config.param_db[0];
private static String driver = db_config.param_db[1];
private static String user = db_config.param_db[2];
private static String pass = db_config.param_db[3];
private static Connection con = null;
private static MySqlConnection _instance ;
private MySqlConnection(){}
public static MySqlConnection getInstance() {
if(_instance == null) {
return new MySqlConnection();
}
return _instance;
}
public static Connection getConnection() {
if(con == null) {
connect();
}
return con;
}
//méthode de connexion
public static void connect(){
try {
Class.forName(driver).newInstance();
con = DriverManager.getConnection(url, user, pass);
} catch (Exception e) {

Re: GWT + mysql (noob questions)
Cool thanks for all the feedback. I think for now I'll just dig into the lower level stuff myself. I'm just going to use the java.sql classes, and handle things that way. I really don't have much data to store in the database at this point anyway. Already since I am using the command pattern so I can more easily implement Gears for offline access, I should be able to use the same encapsulation to put in a Hibernate version of my "live" data access?Anyway, thats down the road a bit. Very much trying to follow the old KISS philosophy on this! Honestly, I can't really say enough about that Ray Ryan talk. At this point I think I've watched it probably 5 times. It got to the point where I had the example gwt-dispatch/gwt-presenter example code open in one space, youtube up in another space, and the pdf of the slides up in another spaceall while coding the patterns in Eclipse. hahaha And yes, Gin is on my current milestone to do list. I've got the basic UI done for most the application (letting the designers fight about the specifics :) )I just implemented MVP/command patterns for the login process. Now I am wanting to be able to store the login data in the database (hence my original question). Then I am planning to unit test my login process, which will include my implementing Gin. Probably should have been more 'test driven' from the get-go, but really wanted to dig in quickly. I plan to write unit tests up front for my future milestones. If you couldn't tell, I have been stuck in a 20 year old legacy codebase for over 10 years.

That is true for the most part but as Charlie said it's not a pure win because getting it to do what you want, how you want it to do it can be very tricky.

I haven't really dug into IBATIS but it sounds like it may be an easier to use ORM. For me, the hibernate full text search is very valuable. It can be very fast but you really need to understand how it works to get it to do things right. The way the handle lazy instantiation often feels obtuse to me and i'm continually getting a better handle on it. There are a few books out on it if you're really interested as well as a lot of documentation online. If you do use it just never trust that it will query for data the way you expect it to. You have to stay on top of it or else it is very easy to cause situations where it will query repeatedly for data that you should be able to get with one round trip. On and BTW, i'm also a huge fan of the MVP pattern. I'm very glad that i saw Ray Ryan's presentation before i got to far into my project. He saved me from having to write a *lot* of boilerplate code. Are you also using Gin? I was reluctant at first because i was getting framework fatigue but it is pretty handy for being able to unittest your presenters.

Re: GWT + mysql (noob questions)
I've used hibernate extensively and have had serious issues with it. The actual SQL code is all generated auto-magically which can lead to problems. I much prefer IBATIS, where the SQL is plainly visible and editable, and you still get simple POJO manipulation. IBATOR can generate most of the sql you will need it also, it has been far less painful for me then hibernate. Just my 2 cents.

Re: GWT + mysql (noob questions)
Thanks for the information. I feel fairly comfortable with GWT and GWT-RPC now. I implemented the command pattern & MVP pattern as per Ray Ryans talk, for my communication over RPC. That gave me a pretty good crash course! I am sure there are details in there I'll be learning along the way though! As for Hibernate, I am just trying to decide if its something to invest time in now. Cause I really hate using technology just for whiz-bang/bandwagon reasons. It sounds like hibernate, when integrated into my app, allows me to avoid having to worry about the lower level SELECTs & parsing results etcetc? All that code is handled by hibernate, so I can just make calls to classes for accessing/storing data and everything is persisted behind the scenes for me by hibernate?

Re: GWT + mysql (noob questions)
I dont have any tutorials at hand but your understanding of where the DB code lies is correct. It's totally on the server side and has nothing to do with GWT. Your GWT app would get access to the data via RPC. The RPC methods would in turn get data from the DB. Hibernate is an ORM (object relational mapper) which allows you to tie Classes to DB tables in a way that is largely transparent to your application. One problem though in using hibernate with GWT is that the classes created via hibernate cant be serialized to the client via RPC (not that i know of anyway) so a lot of people use different libraries to make clones of the faux-POJO's so that they can be serialized. (I do this in the project that i'm working on but i did it by hand) (um, POJO means plain old java object). If you're interested in using hibernate you should probably use it from the start because retrofitting the application after the fact would on undoubtedly be extremely painful. But with that said and with as much as i love hibernate if you're using all of these new technologies together for the first time you may become overwhelmed and hibernate is a fairly involved framework so you might be better off getting a good grip on GWT and GWT's RPC mechanism first. but as always, ymmv On Sep 23, 10:53 am, PJ Gray wrote: > I am writing a fairly large web app using GWT in Eclipse.

GWT + mysql (noob questions)
I am writing a fairly large web app using GWT in Eclipse.My background is as a c++ desktop developer, so while I have used java before, sometimes I stumble on easy stuff. Anyway, I am currently attempting to implement a database to store data from my webapp. I am far from an expert in SQL, but I have done some desktop programming of SQL before, so I feel comfortable enough doing SELECTs and whatnot. (Most recently I did some development using the iPhone Sqlite stuff). Can someone point me to a good tutorial or something that gives an example of storing simple user data in a database from a GWT app? I found a servlet based java/mysql example, so I am concentrating on classes like datasource right now. I can only assume the SQL stuff needs to be contained on the server side of a GWT app anyway, so I was going to start there. But I had questions like: - what is the process for connecting to a database in hosted mode? Is just left to me to get something like MySql installed locally, and then follow instructions like listed here ( http://humblecode.blogspot.com/2009/05/gwt-16-using-jndi-datasource.html) in order to connect? - when I do deploy to a live webserver, is it just a matter of switching the database config (username/password, database name etc)? (as long as I have everything setup in mysql on my live webserver obviously) - how does 'Hibernate' fit into all this? I read about it, and see it mentioned everywhere.It looks like a library for persisting my java objects in the database, rather than pulling information out of my objects and storing the data only? Is that accurate?If so, I could write my persistance layer in such a way that I could start by storing the data raw (Strings, longs whatever), then later as my app becomes more complex, I could implement Hibernate to start storing my model objects directly?

Re: GWT + MySQL
you need at least a server for the transaction between the gui (browser) and the dbms. some uses apache.tomcat or some other java servlet/container/application server. some are using php with extjs, but never let some js on your db. try using json or rpc. if you code the access codes in plain javascript, every honk can manipulate the data, so hide them inside the serverpart ;) gwt is in java, if you are firm with that, try using tomcat (for smaller apps) cause the clustering is not that funny stuff ... later on you can distribute that on different server, with ejb or so .. but that needs some more skills... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Hi all! i am new in this group and i don't know if you already discussed what i am supposed to ask right now. I have a project in our Software Engineering subject, and we used eclipse with gwt for the whole project.

Re: GWT + MySQL Best Practices?
Quickly: For a simple project why not, but as soon as you have multiple project (store / business / dao / webapp ) or if you have some dependencies maven dependencies management is a real plus.

Re: GWT + MySQL Best Practices?
Imho, maven is overdesigned if you don't have junit tests and other stuff. Ant is more than enough for just creating a war file(i do it with one button-click in eclipse). The only manual step is to copy it to your webapps-folder on the server ;-) On 27 Nov., 14:02, "olivier nouguier" <[EMAIL PROTECTED]> wrote: > It does all ;) > From GWT compilation, junit coverage, packaging ... very easily once > you've made the effort . > But I agree that it's quite complex. > > As an example, you can look athttp://code.google.com/p/net-orcades-spring/ > It's maven driven, and quite functional, but It's my very personal > opinion (about my work :) > > > > On Thu, Nov 27, 2008 at 12:11 PM, Lonifasiko <[EMAIL PROTECTED]> wrote: > > > What does Maven better than Ant?

Re: GWT + MySQL Best Practices?
It does all ;) >From GWT compilation, junit coverage, packaging ... very easily once you've made the effort . But I agree that it's quite complex. As an example, you can look at http://code.google.com/p/net-orcades-spring/ It's maven driven, and quite functional, but It's my very personal opinion (about my work :) On Thu, Nov 27, 2008 at 12:11 PM, Lonifasiko <[EMAIL PROTECTED]> wrote: > > What does Maven better than Ant?

Re: GWT + MySQL Best Practices?
Hi, We're also evaluating the possibility of using an architecture composed by GWT + Servlets + MySQL. I thought it was going to exist another option to communicate GWT more directly with MySQL, but seems like a combination of GWT-RPC and servlets is one of the best ways to achieve this interaction with DB. In our test project, instead of Tomcat, we're using JBoss to deploy all the application, both client side code and server-side code, packaged into a unique .war file. At the moment must admit we're also copying files and generating the .war package each time manually, but I've also decided, based on other comments in the group, to use an ANT script to automatize this hellish task, sure it saves me very much time and problems. By the way, do you see any advantages/disadvantages of using JBoss AS to host the whole application? Why did you choose for example Tomcat? Thanks and regards.

Re: GWT + MySQL Best Practices?
For automating the deployment (instead of manually copying) ant is the only way to go. I've heard stories that Maven is even easier, but we haven't jumped onto that band wagon (yet). When we build with no server, we have an ant build file that does all that, and then deploys to our external server. We do it old school and jump out to the file system and run via command line, but I've done from inside Eclipse as well.

GWT + MySQL Best Practices?
Hi guys, I'm developing a project with GWT + Servlets + MySQL. At this point, I've got the project setup using the "-noserver" flag and I have Connector/J configured on an external Tomcat 6 server so that my servlets can access the DB. Communication to/from server is through GWT-RPC . My Problem: This is a bit of a pain b/c anytime I make a change to the servlet code (which resides in the same Eclipse project as my GWT code...and I'd prefer to keep it this way), I have to copy the *.class file (for the servlet) over to the CATALINA_HOME/webapps/myproject/WEB- INF/classes/blahblahblah folder. This seems extremely manual and I'm hopeful that there's a better way to do it. What is the recommended way of doing this type of development? Ideally, I'd it would just pickup the changes to both the client and server code as it used to when I was working in hosted mode. Unfortunately, I couldn't figure out how to get MySQL and Connector/J setup in the integrated Tomcat, so I went with the "- noserver" option and configured it with an external instance of Tomcat instead. This manual copying crap is starting to get super annoying, so I'm reaching out for help. What's the best practices for this? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT+MYSQL
Yes you create it yourself and place your server code, specifically the RPC service, under that folder. You cannot put any server code into the "Client" folder because it will try to compile it into javascript for the browser. jk On Oct 10, 11:58 am, shan <[EMAIL PROTECTED]> wrote: > Hi, > I am new to GWT.i am attempting to connect mysql database with GWT. > > i found a very good example in this > link.http://code.google.com/p/gwt-examples/source/browse/trunk/gwt-test-My... > > if anyone tried this example pls let me know one thing. > > under this mysqlconn folder it has Client, Public, Server folder. > > usually we will have only client and public folder. my doubt do we > need to create that server folder under mysqlconn by ourself's. > > -thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
