Google Map API Weather
Hi, I want to add weather layer to google map. I am using Eclipse n Java programming. But the API I got from gwt-maps group does not contain weather library. Can somebody give me the right link to download. For using the weather layer, I need to have weather library in gwt-map WAR, which I couldn't find in anywhere. If anyone knows the right link or have used it, please let me know. Thanks, Vrushali -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

org.postgresql.util.PSQLException
Hi,
I am getting error when I am trying to connect to Postgresql database
from my program. The code I have written is on server side. And I have
added postgres.sql.jar in run configurations build path. I am not able
to figure out the solution. I have tried using other java classes like
BaseDatasource, etc but getting errors there too.
Program -
public Connection makeDatabaseConn(){
try{
Class.forName("org.postgresql.Driver");
String url = "jdbc:postgresql://
localhost:5432/my_db";
con = DriverManager.getConnection(url,
"postgres",
"password");
con.setAutoCommit(true);
}catch( Exception e )
{
e.printStackTrace();
}
return con;
}
Error -
org.postgresql.util.PSQLException: Your security policy has prevented
the connection from being attempted. You probably need to grant the

Re: Hosted mode issues
Hi,
I went through the link but I am not able to resolve my issue. Can you give
me a example. I am new with Java Programming. But following through the link
also I am getting errors.
I copied the war folder from workspace to
C:\apache-tomcat\webapps\tutorialDemo1
and for arguments in Run confi Eclipse
-noserver -remoteUI "${gwt_remote_ui_server_port}:${unique_id}" -startupUrl
TutorialDemo1.html -logLevel INFO -codeServerPort 9997 -war

Let me know what I am doing wrong.
Thanks,

Hosted mode issues
Hi I want to use GWT hostel mode so I can access other URL's using
sendRequest() without any issues. I searched all the earlier posts and
couldn't get the right solution for how to use hosted mode or edit the
Program Arguments or VM arguments.
Following code I have put in Program Arguments:
-port 8080 -server
com.google.appengine.tools.development.gwt.AppEngineLauncher -remoteUI
"${gwt_remote_ui_server_port}:${unique_id}" -startupUrl
TutorialDemo1.html -logLevel INFO -codeServerPort 9997 -war C:\Users
\Vrushu\workspace\tutorialDemo1\war
edu.xml.gwt.ibm.tutorialDemo1.TutorialDemo1
The html pafe displayed is blank.
I want the url with localhost:8080 so I can access Jar file from
Tomcat and also interact with other servers online.

Re: RequestPermissionException: URL is invalid or violates the same-origin security restriction
Thanks Jen, Can you give me a example for the third option for proxy. I am new with Java and GWT both. It will be very helpful if I have a example. I am using Apache Tomcat webserver. Proxy will be more useful since I will need to interact with few more servers in future.

No source code is available for type javax.xml.parsers.DocumentBuilderFactory
Hi,
I am new to Java and GWT. I am trying to parse a xml, which I have
written as stringbuilder.
1) I tried using XMLParser.parse(xmlstring); but it gave a
DOMException tat string is crossing max length. Is there any way to
work around this.
2) I used DocumentBuilderFactory ... the code is as follows. It gives
the error as
No source code is available for type
javax.xml.parsers.DocumentBuilderFactory - It is some sort of
Inheritance issue. But I am unaware of what exactly inherit name i
should be using. Please guide.
