hash - GWT + JBoss + MessageDigest + "SHA-512 not supported" -


I have found some strange behavior, and I think it will interfere with reporting here, (As I did not find any clue on this problem by asking Google).

So, my environment is:

Java 7.25

GWT 2.5.1

Jboss 7.1.1

I have done some login workflows like this:

1) Enter the customer login / password

2) The password is SHA-512 on the client side head

< P> 3) Only the palm password on the client side is snuffed and then head on the SHA-522 server side.

FYI, this is the same function hashing SHA-512 on both client and server side. The code to select hash algorithm is: 

  Message digest digest = mesedgadget.jestinstance ("SHA-512");

When I run my project on GWT Development Moded (one with Embedded Jettie Container), everything goes fine.

Then I generate a war of my project, and employ it on zebus, and the problem is: Method MessageDigest.getInstance ("SHA-512") e -getMessage () => "SHA-512 Not supported "with NoSuchAlgorithmException but only server side hashing on client side is fine (so basically, RPC method sends an empty password to server instead of SHA-512)

I do not think This is expected behavior, and I wonder if someone is about it Some clues in ATM I do not know what the origin of the problem is, I am looking deeply:

  • Trying with gwt 2.6.1 (even though the changelog is like this <
  • Trying with other hash algorithms
  • Checking war construction logs (maybe there is a Maven problem? I suspect but who knows )

Any suggestions will be greatly appreciated :)

I guess the expected behavior is if you check the list, then java.security * is not it works in Dev mode because it runs within a real JVM, not compiled with Javascript.

But why do you also need to have a password hashing in the client? Imho it should be server-side.

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
