java.net.InetAddress is a restricted class Issue
Hi, I am a GWT novice / newbie. I have written a GWT app that connects to MySQL. While I am trying to get DB connection. I have got the error in the subject java.net.InetAddress is a restricted class'. I tried to find solution for this issue. The only solution right now is to disable the Google App Engine. A lot of people get alright after they follow the suggested solution. For my case, I tried to disable by unchecking the Use Google App Engine check box in project properties window but after that i am not able to run the app from browser anymore. For that reason, I tried to create a war file of my work and deploy it to TOMCAT6 but still I am not able to get it solved. Is there any body who can help me out there? I do need a help to solve thing asap as I am gonna use this GWT for my project. Thanks in advance. FYI, I am using : OS - ubuntu 9.10 Eclipse version - 3.5 GWT version : 2.0 jdk version : 1.6 -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Can you paste logs or error messages or stack traces after you disabled GAE? --Sri On 25 April 2010 01:23, A.K alexanderfut...@gmail.com wrote: Hi, I am a GWT novice / newbie.

are you sure that whatever java code (except for the java.util package) you're using is not listed under .client package?

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].

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 nbmku...@gmail.com 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.

Re: java.net.InetAddress
You CAN make a browser go to another server, but there's no way to receive information from it. Its possible there's some hacky way to figure something out, but this is just doomed to failure, because email servers don't have to be webservers, and vice versa. For example, there are still loads of servers that don't direct FOOBAR.com port 80 to the webserver, only www.FOOBAR.com. And yet email address are virtually always [EMAIL PROTECTED] and not [EMAIL PROTECTED] Thus, the answer is not only - no, you can't do this, but the answer is: No, you're Doing It Wrong. You don't validate email addresses by checking if there's a webserver running on it. If you must check it... you send an email to it, with a link in it.

Re: java.net.InetAddress
No, you can't do what you want on the client. If you want to validate
that the given domain has email capability you'll need to send a
request to your server side and then lookup if the domain as any MX
records configured for it. If so, you know at the very least that
someone's registered an email server for the domain.

Is there any way to access the class java.net.InetAddress--or
something providing similar functionality--from the client side of a
GWT app? I know that everything compiles to Javascript so I guess the
question would be whether that imposes a constraint such that this is
impossible.
I'm trying to verify whether a given email address is valid when it is
entered in on the client side by a user. Ideally I'd like to do
something like the following to check if a given domain name is valid:
InetAddress x;
try {
x = InetAddress.getByName(www.google.com);
System.out.println(Success: got to google and the IP address is:
+x.getHostAddress());} catch (UnknownHostException e1) {
System.out.println(Failure: didn't get to google, Unknown host
exception);
}
But I'm not sure if anything like this can be done on the client
side. Any ideas?
Thanks!!
