JFrame Reload After MySQL Update
Apr 22, 2014I've got a similar problem like here: URL...
private void btnAktualisierenActionPerformed(java.awt.event.ActionEvent evt) {
if(sql.conOK) {
tabelle.table.tableChanged(null);
tablePanel.remove(scrollPanel);
// The following fetches the new database data and adds the new jFrame
tableExists = false;
this.getTable();
tabelle.setOptions();
}
else
lblStatusCon.setText("Bitte zur Datenbank verbinden.");
}
this is what I've been doing. It shows only the new jTable when I resize the window.

JavaFX 2.0 :: JavaScript Not Working After Reload In WebEngine

Mar 19, 2015I'm beginner with javaFX and i need to change language of the screen. but how to reload the screen when the language was changed. The application have a button where have the language available. I want just refresh screen when the user change language. Here is the start method to show the stage.
@Override
public void start(Stage stage) throws Exception
{
this.stage = stage;
Locale locale = Locale.getDefault();
ResourceBundle rb = ResourceBundle.getBundle("resources/Label",locale);
[Code] .....
Here is the function to change the language(in the same class with start function),the rb is the new ResourceBundle:
public void refresh(ResourceBundle rb)
{
//change the language here
}
1. I don't want to use the resourceBundle to get value in resource file and set label in scene one by one.like following:
this.btnLabel.setText(rb.getString(key.test));
...
2. I don't want to reload the scene,like following:
public void refresh(ResourceBundle rb)
{
try
{
loader = new FXMLLoader(getClass().getResource("FXMLDocument.fxml"),rb);
root = (Parent)loader.load();
[Code] .....
So do we have a solution to just set the resourceBundle and reload the scene easier?

Servlets :: Submit Buttons In JSP File
Apr 30, 2014A user can dislike/like a topic. However I have to submit buttons in my jsp file, the issue is that when a user presses like/dislike it should print out on the consile line. It does that perfectly but it prints out both when it should only print out either like or dislike.
My JSP code:
<form name = "ViewTripServlet" action="ViewTripServlet" method="post">
</br>
</br>
</br>
<input type="image" name = "like" value="submit" src=images/like.png onMouseOver="this.src='images/like.png'">
</br>
</br>
</br>
<input type="image" name = "dislike" value="submit" src=images/dislike.png onMouseOver="this.src='images/dislike.png'">
</form>
Servlet Code:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ViewTri vT = new ViewTrip();
vT.user_like(request.getParameter("like"));
vT.user_dislike(request.getParameter("dislike"));

Servlets :: Reset URL To JSP File After Servlet Call
Feb 14, 2014I am a JSP/Servlet newbie currently adding the first servlets to a web site that had been static all along. My local instance worked great but the servlets did not respond on the test instance. Apparently, my hosting service provider requires me to use an invoker servlet mapping.
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
Adding this to local web.xml broke the application but the servlets respond on test instance (when their calls are not preceded by another servlet call). A Servlet fails when it is called immediately after another servlet has been called.
What I saw happening on test is URL for first call is of the form:
xxx.org/<app-name>/servlet/<servlet-name>?Id=1
And URL for the second call became:
xxx.org/<app-name>/servlet/servlet/<servlet-name>?Id=1
The servlets are invoked using "href=servlet/<servlet-name>?Id="
How can I avoid the inclusion of 'servlet' in the URL and reset the URL to the JSP page it navigates to after processing of the servlet?
P.S.: I am also trying to enable the Invoker servlet on local so I can troubleshoot easier. I went through the changes to Tomcat's web.xml and context.xml. However, my local servlets did not respond even after calling them using "href=<servlet-name>?Id=". Is there a way I can check if my invoker is active?

Servlets :: No Error Shown While Compiling Java File But Also No Output
Jan 22, 2015I made a web app to test the ServletContextListener in tomcat according to the book head first servlets and jsps and used the code
out.println("test context attributes set by listener<br>");
Dog dog = (Dog) getServletContext().getAttribute("dog");
out.println("Dog's breed is: "+dog.getBreed());
in the listener class.But the output is showing the first line only and the second println() is not showing any output whereas my Dog class compiled successfully and I didn't see any NullPointerException as expected in the book but somehow it seems like the problem is in the 2nd line of code only but I don't know what.
I also tried to add a 4th line at the end with println() only but with a simple text even that is not running but when I put that same line after the 1st line, the output is shown.I am unable to see what has gone wrong in the 2nd line of code.
Servlets :: Response Content Type - Download CSV File With Records From DB

Servlets :: Large File Upload From Client To Content Management System
Sep 3, 2009I have a requirement where a large file (100 -200MB) is uploaded from the client to a content management system. I am using a servlet with Apache Commons File Upload API. Apache FileUpload has 2 ways of handling files,
1) Non-Streaming
2) Streaming
Currently I use the Non-Streaming approach where the servlet stores the file in a temp location and upload the same into the content management system - This is taking lot of time so I am trying to implement Streaming API.
Content Management API supports streaming in 2 methods,
a) SetContent - Takes the file's ByteArrayOutputStream as input -> This gives OutOfMemoryException because the file being large
b) AppendContent - Takes the file's ByteArrayOutputStream as input -> This method can be called multiple times to upload the large file but I dont know how to do this. The Apache File Upload gives InputStream of the file and I need to split that into chuncks and append into the content management system.
How to convert InputStream to 4KB ByteArrayOutputStream so that I can use the AppendContent method in content management API?
