Re: PasswordTextBox: Making password character visible for a moment
Hi Raja, I think the way to achieve this is by making use of the keyboard listener functionality. This might need some explicit code. First you define a normal textbox, then when the user types something, set a keyboard listener, and then a timer. Then you can temporarily store the that character of the password in some string which keeps getting appended as and when the user keeps typing. And with every keyboard key-in, call the keyboard listener, then the timer say for 100 ms and then replace that with a * or #. That should get your logic working. Just for your info, the only reason why this was introduced in cellphones was because, in a cellphone, each button might correspond to multiple characters. If you implement this algorithm in normal web-pages (which I feel would not really be needed) then you might need to have a specific logic to distinguish between a browser-access and cellphone-access and enable this logic only for the browser version and have a normal password textbox for the cellphone version. Just think over!!

Re: How to avoid Double Submit in GWT?
One nice idea would be to bring a popup with a loading kinda image.. Since the popup is there the user will not be able to click anything and the popup would also server as a means to display loading.. The advantage here is, if ur page has lot many buttons, rather than making each button disabled and then enabling them back when the service call is completed, this will be a simple mechanism to achieve what you need. In case u dont need the "loading" displayed, u can just use a blank popup!! Regards, W On Wed, Dec 29, 2010 at 1:54 AM, Srividhya Ramachandran wrote: > How to avoid Double Submit in GWT?

Re: Help: Development of large App with GWT
Hey create a project which by itself acts as a GWT designer (Someone has already done a similar thing actually!!, with the DND options and all), Then u can have modules for server interaction which by itself can be automated so that all u need to do is indicate the table name and u get the data automatically!! This will be like a complete package for developing web application and u can claim that people who use this project just need to do some customizations rather than coding!! This will definitely turn out to be a really interesting project!! (P.S. : Later u can share the code with the GWT community even so that it can make the work of developers really really easy!! :-) ) Regards, Abhiram On Mon, Oct 4, 2010 at 2:09 PM, Noor wrote: > This is persuading but examiners can tell if even i didn't write ant > javascript, i did write it in java > > -- > You received this message because you are subscribed to the Google Groups > "Google Web Toolkit" group. > To post to this group, send email to google-web-tool...@googlegroups.com. > To unsubscribe from this group, send email to > google-web-toolkit+unsubscr...@googlegroups.com > . > For more options, visit this group at > http://groups.google.com/group/google-web-toolkit?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Send e-mail in GWT
The simplest way to do this would be, Create a front end page with the neccesary stuff like Recipient's id, Subject Title, Mail Body and send all this data to the server side alone with the sender username and password also as this is needed for the authentication. Then, make use of *mail.jar *for sending the mail from the server side. This has functionality to send the email and with all the necessary parameters like Mail Body, Subject Title etc.. (Dont know the exact function names, but there is a provision!!). This shud get ur email functionality working!! ~ Abhiram Wuntakal On Mon, Oct 4, 2010 at 12:07 PM, naveen wrote: > Hi team, > > My requirement is to send a mail from my website. > > i will elaborate the requirement.

Re: How to integrate an open source web app into a GWT application
Hi, I am really not sure if this might be totally wrong. But u can take this as a suggestion from where you can start the solution. Embed the JSP code in html and make that part of a html widget. You can place this html widget in one of the panels. Then u can build any other GWT sub application in the other sub-panels. Not sure if this is exactly right, but I think this shud work..

Re: Upload folders and/or Upload Files already on the server
Hi Guru, The way web applications work I guess such an activity is not possible. The only thing u can do from a client side is to allow him to upload a particular file, u can control other activities like getting the list of files if the user specifies the directory name. On the other hand you can plan a logic by which, the user is able to select the files and drag and drop into a space from where you can upload the files one by one from your code. This would be similar to the way you do multiple file upload in Gmail. You can try to implement that functionality which might solve your problem.

Re: Mouse Over Image
Hi,
I had implemented a very similar functionality, where I had to display a
label as soon as there is a mouse-over on the image and where there a
mouse-out, the label had to disappear. This is what I did.
defined an image at a position fixed Rootpanel.
defined a html(instead of a label) at the centre of the image (as per x,y
coordinates)
initially made it setvisible(false) just the was u did
for a mouse-over set the html visibility true
for a mouse-out set the html visibility false.
This worked perfectly fine for me. i guess the trick is to use the HTML
widget instead of the label, although u will get all the properties of the
label with that. use this and it will work fine.
let me know if u need any other info

GWT Print
Hi, I have been using the standard GWT printing methodology but I see that the border lines and the grid lines get missed out in the print. And the final printout only has the texts without any decorations. Can someone suggest a nice GWT Print logic where the grids/scrollTables appear with the borders and all ?

Re: help for sending e-mail using rpc / gwt
Hey Felipe,
Here is what you need to do:
Client Side :
SendEmail.java (Entrypoint or a Popup) - A very basic design would be of
a TextArea / RichTextArea where you can have the body of the email written.
Then you can provide a "Send" Button. On the click of the send button,
create an object of the Async class and call the SendEmail function with the
String parameter.
SendEmailService.java - A simple method with a String parameter,
something like this.
public void SendEmail(String body) throws Exception.
SendEmailServiceAsync.java - A simple method again with a String
parameter this way:
public void SendEmail(AsyncCallback callback).
Server Side:
SendEmailServiceImpl.java - Implement the function I had sent earlier and
you shud be able to send the email with that successfully.
Note : If you want to send other parameters like username etc from the
client side, then I would advise using a Vo rather than a String parameter
alone.
Hope this helps..
Let me know if u need any other help. No matter how silly.. (I have asked
sillier doubts when I had started understanding GWT, he he)
Regards,
Abhi

Re: help for sending e-mail using rpc / gwt
Hi Felipe,
RPC implementation would be simple. Just write an ordinary
RemoteServiceServlet and write a function to pass a String parameter (or a
Vo) with the emailBody to the ServiceImpl code. From ServiceImpl, you can
use the code below to send the email.
Let me know if this answers your question.

Re: help for sending e-mail using rpc / gwt
Hi Felipe,
This block of code would help you send an email from the application. The
trick basically is to get the textual data from the client side and pass it
to the server side and then use this piece of code to send the email. This
is actually with the file attachment feature even.
Initially, you need to have a few variables declared for the username,
password, SMTP etc...
private static String SMTP_HOST_NAME = "abc-abc.abc.com";
private static String SMTP_AUTH_USER = "a...@abc.com";
private static String SMTP_AUTH_PWD = "abcpassword";
private static final String emailMsgTxt = "Sample Message - Testing the
email application";
private static final String emailSubjectTxt = "Sample Mail";
private static String emailFromAddress = "ab...@abcde.com";
private static final String[] emailList = new String[100];
String fileAttachment = SRCFOLDER + "sample.pdf";
public void sendEmail(EmailDetailsVo emailVo) {
emailList[0] = emailVo.getEmailRecipient();
Writer output = null;
String text = "sample Text";
OutputStream file;
System.out.println("Inside send email2");
fileAttachment = SRCFOLDER + "sample.pdf";
try {
file = new FileOutputStream(
new File(
SRCFOLDER + "sample.pdf"));
Document document = new Document();
try {
PdfWriter.getInstance(document, file);
document.open();
document.add(new Paragraph(String_Body_Of_The_Email));
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
document.close();
try {
file.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", SMTP_HOST_NAME);
props.put("mail.smtp.auth", "true");
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getDefaultInstance(props, auth);
MimeMessage message1 = new MimeMessage(session);
try {
message1.setFrom(new InternetAddress(emailFromAddress));
message1.addRecipient(Message.RecipientType.TO,
new InternetAddress(emailList[0]));
message1.setSubject(emailVo.getEmailSubject());
message1.addRecipient(Message.RecipientType.CC,
new InternetAddress(emailVo.getCcEmailAddress()));
// create the message part
MimeBodyPart messageBodyPart = new MimeBodyPart();
// fill message
messageBodyPart.setText(emailVo.getEmailBody());
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(fileAttachment);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName("MainPdf.pdf");
multipart.addBodyPart(messageBodyPart);
// Put parts in message
message1.setContent(multipart);
// Send the message
Transport.send(message1);
} catch (AddressException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// return null;
}
public class SMTPAuthenticator extends javax.mail.Authenticator {
public PasswordAuthentication getPasswordAuthentication() {
String username = SMTP_AUTH_USER;
String password = SMTP_AUTH_PWD;
return new PasswordAuthentication(username, password);
}
}

Re: How to prevent the big and specific file to be uploaded
Hey Ankit,
AFAIK, you wont get to know the size of the file unless you transfer it to
the server. But from the client side you can restrict the file extension by
extracting the file name as follows :
final FileUpload upload = new FileUpload();
upload.setName("uploadFormElement");
absolutePanel.add(upload,8,37);
String fileNameVal = upload.getFilename();
You can put appropriate check to ensure that certain kind of files alone
can be uploaded.
HTH,

Abhi

Quick question on GWT Print
Hi all,
I am trying to use Print class for printing the contents of a
particular Popup Panel.
I believe, i need to use the
Print.it(DOM.getElementById("myId"));
code for this functionality. But I am not able to set the Id for
the panel. Can someone please send me the code to set the id for a
particular element?
Thanks and regards,
Abhiram

Re: image help
Hey I have this not-so-technical work around for u. Apply a Mouse over handler for the image. on a mouse-over, just change the image to some other image (probably a smaller one which says "Dude, U cant download this!!!") and again on a Mouse-out bring back the original image. Guess that will solve your problem and people will not be able to download it... But as Sripathi says, it would be better to show a smaller size, low resolution image, as people can always do a ScreenPrint and extract exactly that image alone!! Hope a combination of these two things would solve ur problem. ~ Abhi On Tue, Mar 30, 2010 at 3:02 AM, Sripathi Krishnan < sripathikrish...@gmail.com> wrote: > but if they can just right click it and "Save Image As" there isn't any >> point. >> > > Disabling right click is no solution.

Printing the contents of TextArea
Hi All,
I am trying to print the contents of a textArea. But i am able to
print only the part of the text which is visible and not the ones that
I see when i scroll down. Can someone one tell me the proper print
functionality that needs to be used to actually display the entire
content of the text area (same behaviour is seen in scrollpanel even).
Right now I am using this functionality.
native void printx(String s) /*-{
var win1 = window.open('', 'reportwindow');
win1.document.open();
win1.document.write("Report");
win1.document.write(" body,td {font-family:sans-
serif;font-size:10pt;}");
win1.document.write(" \r\n")
win1.document.write("function Print(){window.print()}")
win1.document.write("");
win1.document.write(s);
win1.document.write("");
win1.document.close();
win1.close();
}-*/;
public void printIt(String html){
printx(html);
}
Please let me know what is the approach to be followed.
Thanks and regards,
Abhiram

Query regarding printing a widget
Hi All,
I just needed some help regarding a functionality where i need to
print the contents of a widget.
I am using the Print.it() function. I am able to print the HTML
string using the function Print.it("Just Print.it()!"). This
happens successfully, but am not able to print the contents of a
particular rootPanel. The rootPanel has a couple of buttons and a
textBox with some text. I have been using the following command for
this
Print.it(rootPanel.get("__printingFrame"));
I know I am missing something here. But am not sure how to proceed.
When i fire this command I just get the text " [object] " printed.
Can someone help me out at this point? What else do i need to do to
get the contents of the TextBox printed.
This was the entry that I made in html file.
I saw some previous codes where I got some info, but am looking out
for a very specific example where a textBox is passed as an argument
and I get only the contents of it printed.
Can someone please suggest what do I need to do?
regards,
Abhiram

Re: Gwt KeyboardListener
Hi Jagadesh, The problem would be because of the place of definition of your widgets. Guess right now you are defining the Age TextBox after FirstName TextBox.

Re: how to send variables in form panel
Hey Yoez, Not sure if it helps. But i have a workaround solution for this. Make it a two-step process. First use a RemoteServiceServlet to pass across your variables to the server side and then save these values into some variables on the server side. Then you can use a HTTPServlet to pass across your file contents to the server side. Now you have the file as well as the variables.

Re: File Upload not working after migrating to GWT1.7
Hi Eric,
Thanks for that. But I had a similar piece of code earlier, but I had
*form.setAction(GWT.getModuleBaseURL()
+"/UploadServlet"); *instead of *form.setAction(GWT.getHostPageBaseURL() +
"UploadServlet");
*I was getting the error "The requested resource
(/GWTFileUpload/UploadServlet) is not available." This is the same error
which I am getting when I replaced my setAction with the line of code which
you suggested. Not sure what is the problem. Everything seems to be fine.
You have any clue about this?

File Upload not working after migrating to GWT1.7
Hi All,
I had my File Upload module working properly in 1.5.3. But it has
not been working after I migrated to GWT 1.7.
I realised that "addFormHandler" is deprecated in 1.7 and so I changed
it to "addSubmitHandler". Earlier the setAction was set as
form.setAction(GWT.getModuleBaseURL() +"/MyServlet");
I changed it to
form.setAction("C:/apache-tomcat-6.0.16/webapps/GWTFileUpload/WEB-
INF/classes/com/abc/pt06/uploadfile/server/UploadServlet");
which is the real path of my servlet after starting the tomcat.
But still it does not seem to be working. I just get an "Error on
Page" alert in IE and in Firefox, i get an alert like "Firefox does'nt
know how to open this address, because the protocol(c) isn't
associated with any program."
Can someone please suggest what I need to do to get this working. Or
some sample code where FileUpload has been working properly in GWT
1.7.
Regards,
Abhiram

Re: GWT Button style using HTML - Mozilla Compatibility
Hi Zak,
Thanks for that.
But i was planning to have uniform style for all the buttons. I have some
15-20 different kinds of buttons. I dint want to write a separate CSS for
each of them. I just realized that using HTML would be a really convenient
way of implementing the icons for buttons. And I finally got the right piece
of HTML code which works perfect across all the browsers and my browser
compatibility issue got solved!!
Thanks anyways..

Re: GWT Button style using HTML - Mozilla Compatibility
I got some really cool styles with HTML tags and so thought of sticking on
to it. Any idea why the image which I set on the button using HTML did not
appear in Firefox?

GWT Button style using HTML - Mozilla Compatibility
Hi all,
I used the setHTML property for the Button to get some really nice
styles for the buttons in my application. This works perfectly in IE
but does not seem to work in Mozilla and Chrome. In Mozilla and Chrome
I dont see the images on the button which are visible on IE.
My sample code is as below:
button.setHTML(" Home ");
Can someone please let me know if I am missing something here?
regards,
Abhiram

Email from GWT appliction
Hi all, I am stuck up at a particular place where I need to send an email from my GWT application. Although it is majorly a Java related query, thought u guys might help me out with this one.. I have an application to send an email and it works properly at my end. I am using the Gmail SMTP server which is "smtp.gmail.com" and am able to successully send an email. FYI, i tried this code from a system in India. But i tried the same code at another system placed at US, but the code did not work. It says could not connect to the SMTP host. I tried a few other SMTP addresses namely "gmail-smtp-msa.l.google.com" and "gmail-smtp.l.google.com" and all these work properly from India but they dont work properly from the US system. Can someone please tell me if I need to make any other changes to get this thing working or is there any method by which I can know what is the SMTP that I need to use.

Wanted to know if there are any complications which might occur later (during migration to another version or something!!).

Re: Image icons for Widgets
ok, i will elaborate a bit...
there are 2 buttons, save Button1 and Button2. Button1 needs an image Image1
and Button2 needs Image2.
The styles of both the buttons are same except for the images that appear on
them.
I am writing two styles Style1 with the background-image as Image1 for the
Button1.
And the other Style2 with the background-image as Image2 for the Button2.
Cant I not write a single style for both the buttons and some code to
indicate which image would be used for the button (dynamically).
That would save me the task of creating multiple styles for all the buttons
that I have.
Please let me know if there is any such functionality available...

Image icons for Widgets
Hi,
I have a requirement where in I need to add image icons for widgets
like buttons and menu items. I am using a CSS style for this wherein I
specify the background image this way.
.Style1 {
background: url(Image1.gif) no-repeat;
text-align: right;
}
This works fine, but was wondering if there is a better way of doing
it. Coz, in this approach I need to create a new Style for each and
every widget. Although the background for all the widgets are same,
there are multiple css styles created because of this approach. Can
anyone tell me if there is a more optimal method of doing this.
Regards,
Abhiram

Re: Passing a argument to GWT application
Not sure if this is the right thing to do. but u can try the history token as a work around. Pass the rowid as a history token to ur application url... Then retrieve the history token in ur code and u can later query the database accordingly.. Dont u want to put a textBox in the initial screen which takes up the rowid as the parameter and gets u the data accordingly? that i guess, would be the most logical thing to do... regards, Abhiram On Tue, Jun 9, 2009 at 4:19 AM, OffTheWall wrote: > > I want to pass my GWT application a recordID at the time I call the > URL.

GWT Incubator - ScrollTable with TextBox
Hi all, I wanted to know if Scrolltable is a panel good enough to hold TextBox widgets. I have created a ScrollTable (using gwt-incubator_1-5_Dec_28) with TextBoxes in a particular column and labels in other columns. I can extract the label value using the function "scrollTable.getDataTable().getText(row,col)". But i am not able to get the value at the TextBox using this function. It always returns null. Am i missing something here? Is there any other way to get the value of the text in the textBox present at a particular cell? PS : I am not using the TextBox array logic to get the data at the textBox because there are certain problems when i delete the row in the scrollTable.

Hi all, I am facing a strange problem. After i load my menu items (its a combination of horizontal and vertical menu bars), i see that the menu becomes pretty slow.

Re: Images for Push Buttons
Hi Donald,
Thanks for your reply, but i am sorry, i guess u have misunderstood my
problem. My problem is...
I have 3 buttons Button1, Button2 and Button3. All three have different
functionalities. So I have a different image to be displayed on each of the
buttons. If i use CSS then i need to have a different style for each of the
buttons. But all the buttons look similar except for the image that gets on
top of the button.
My doubt is, is there a way to have the image displayed on the Button by
setting the image directly from the Code (Not from the css), so that when i
define the button i have the image defined for it as well.
Hope my doubt is much clear now. Please let me know if you can suggest any
solution for this problem.
Best Regards,
Abhiram

Best approach for saving and displaying images
Hi, I am developing an application for displaying images which are stored on the server. Which would be the best approach to save the images on the server? 1> Save the image as a CLOB data in the database or 2> Save the images in a folder in the server? 3> Or any other better technique... :-) Please suggest.. regards, Abhiram --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Images for Push Buttons
Hi, I wanted to know the procedure to add images to PushButtons. I have found a css style by which i can add it. But that would mean that for every button with an image, i need to write a style rather than having a single style. Is there any way to specify the image for the face of the push button from the code itself? regards, Abhiram --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Imports in the Client Side
Hi all, I am developing a password hashing approach for my project. I first convert my password string into a MD5 String and and send it across to the server side where i compare it with the MD5 string saved in the database. I used a code for doing the string conversion to MD5 at client side but I am getting errors for the following import statements that I used. import java.io.FileInputStream; import java.io.InputStream; import java.io.UnsupportedEncodingException; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; And the error was something like "java.io.FileInputStream can not be found in source packages. Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly." Please let me know if i am missing out something as I am not sure what i need to add in the .gwt.xml file for this. First of all, is it possible to put this code in the client side? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Reading XML on Client
I dont think so u can do any such operations on the client side. You can rather use the file upload widget, transfer the code to the sever side and make use of simple File Read opeartions to read the contents of the XML file. Then you can bring back this data and display it on the client side. hope this helps. regards, Abhiram On Thu, May 14, 2009 at 3:50 PM, Pints wrote: > > Hi, > > Can any share the ideas that how can i read XML on client in GWT? > > thanks, > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Sending email from Server Side
Hi Salvador,
Thanks a lot for that quick response. Well, i am not much familiar with the
protocols.
I used the smtp.gmail.com instead of the ip string. Now i am getting stuck
at an other place and I am getting an error like "gwt
com.sun.mail.smtp.smtpsendfailedexception: 530 must issue a STARTTLS command
first."
Please suggest if u know a way out of this issue.
Thanks,
Abhiram

Sending email from Server Side
Hi all,
I am writing an application to send an email from the server side. I
am using the mail.jar for this purpose. I have written a function for
this as below:
protected void sendMessage(String smtpHost, String fromAddress, String
fromName, String to, String subject, String text) throws
UnsupportedEncodingException, MessagingException
{
System.out.println("ABC");
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", smtpHost);
// Get session
javax.mail.Session session = javax.mail.Session.getDefaultInstance
(props, null);
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress(fromAddress, fromName));
// Set the to address
message.addRecipient(Message.RecipientType.TO, new InternetAddress
(to));
// Set the subject
message.setSubject(subject);
// Set the content
message.setContent(text, "text/html");
// Send message
Transport.send(message);
}
and i am invoking the function using this line of code.
sendMessage("209.85.171.83", "abhir...@gmail.com", "abhiram",
"abhir...@gmail.com", "Hi", "Message-Body");
Here, i found the ip address is of gmail.com which i got by pinging
for gmail.com. Please let me know if this approach is right as I am
getting an error like "Could not connect to SMTP host : 66.249.93.109,
port:25 ".
Thanks and Regards,
Abhiram

Re: Image Quality Affected during File Upload
Hi Vitali, I finally was able to solve the problem. Actually i had converted the bytestream to a string as an intermediate step. Then was converting the string back to a bytestream before writing this to a file. During this process, i used to lose some data i guess. I changed the code so that the data gets into the file directly from the original bytestream and it worked perfectly well. Thanks anyways, for your suggestions!! regards, Abhiram On Sun, May 10, 2009 at 10:06 AM, abhiram wrote: > > hi vitali, > > i am sure there is no problem with my viewer.

Re: Image Quality Affected during File Upload
hi vitali, i am sure there is no problem with my viewer. I believe the data is getting tampered when recieved by the servlet. Further, one more thing that i noticed was that, if the image is of low quality say a "16 Color Bitmap" image, then the data is getting transferred almost perfectly and the image is being seen perfectly. So,i thought, higher the resolution, the data is getting tampered... Please let me know if something needs to be done at the servlet side coding for capturing the data perfectly...
