The slimbox JS lib is not working
Hello. I want to be able to import the html code of another web page which is on my web server to my gwt web app. I use this code to download the content of a html page on my web server: http://codepad.org/aiVlWCt2 . This is my entry point html (top part) http://codepad.org/k5zMcqJ2 where i load the js libs i want to be able to use. This http://codepad.org/XiReL6EV is the html file i import to my gwt web app by using the RequestBuilder. The contents of that html file are imported fine, but the js slimbox2 js lib is not working at all. What can i do to solve this? When I press on one of the images the slimbox script executes and does the animation as expected. This behaviour happens when i dont comment out the libs from the imported html file and I use it to my web app by using a Frame. I don't want to use a Frame, because it makes my web page looking nasty even if i set the Frames border equal to none. I don't want to have java on the server side because i want to be able to find a cheap hosting service to deploy this web app. I prefer not having a server side at all to be honest. Please enlighten me to solve this problem. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

gwt + email
Hi. I made an RPC for sending an email
this is the Impl file:
package faceRecognition.server;

EmailService {
@Override
public String send(String emailTo, String subject, String body) {
String msg = "";
msg = Gmail.send("this", emailTo, subject, body);
return(msg);
}
}
when i commented out the line "msg = Gmail.send("this", emailTo,
subject, body);"
everything is ok. the problem is in the method Gmail.send:

getPasswordAuthentication() {
return new PasswordAuthentication(username,

}
});
session.setDebug(debug);
Message msg = new MimeMessage(session);
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress
[recipients.length];
for (int i = 0; i < recipients.length; i++) {
addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);
// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/html");
//Transport.send(msg);
javax.mail.Transport.send(msg); //HERE I GET THE FOLLOWING
ERROR
}
}

2. how can i just say to the browser that the pdf file is in the
Files dir and dont declare the host as well?

include html from a gwt web app
When programming in jsp you can use the jsp:include when you want to
include an html file in that part where the tag is. Can i do something
similar in my gwt web app?
Like when i press a button to do
rp = RootPanel.get("mainContainer");
rp.clear();
//here do the include
This will help me separate html from my gwt web application and when
pressing several buttons to load the specific context. Any ideas?

GWT upload file handle exception
hi I have a form which sends a request to a servlet for uploading a
file. How can i handle the exceptions? THe exceptions are caught in
the doPost method of the servlet. The form in my app looks like:
form = new FormPanel();
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
form.setAction("/myfacerecognitionwa/upload");
form.addSubmitHandler(new SubmitHandler(){
@Override
public void onSubmit(SubmitEvent event) {
try{
}catch(Exception e){
Window.alert("Error: " +
e.getMessage());
return;
}
Window.alert("The file was uploaded!");
}
});
vPanel = new VerticalPanel();
upload = new FileUpload();
upload.setName("upload");
vPanel.add(upload);
vPanel.add(new Button("Submit", new ClickHandler()
{
public void onClick(ClickEvent event) {
form.submit();
}
}));
form.add(vPanel);
What can I do? I want to catch the exceptions and show them using
Window.alert("Error: " + ioe.getMessage());
