I have an arraylist in my servlet which i need to pass to jsp as a response for a javascript call. This is an arraylist of DTOs. There are 24 DTO objects in the list. The DTO has an int variable and a HashMap. And i need to pass this into the javascript code in my jsp page. Do i use json? Do i send the entire list as a json object or should i iterate through the arraylist (from servlet) and serialize all the DTOs and pass that to the jsp?

I have a SOAP Client with wsdl to send a query to a SOAP Server. Along with the SOAP response I am supposed to attach a generated csv file (Not required to open and read - just attach).
SOAP Handler has been implemented at server.
Since it is client code I am not supposed to paste the exact contents online.
I can create new SOAPMessage and use AttachmentPart to attach the file but I am stumped regarding where to set it as response. We have used only javax.xml and apache.cxf.

I am calling a SOAP based webservice using JAX-WS and a client jar. I want to get a request and response somehow and save it for audit purposes. How I can do this?
When I google it, only Handlers come up, but, as far as I understand, it is not applicable on client side.
I have been using JavaFX for some time now and have encountered many performance issues, mainly with the initial display of GUI elements. For example, a simple stage with a table view (with about 10 columns) and chart takes about 5 seconds to display. A color picker will take about 3 seconds from the time I click the control to when it displays the pallet. This only happens when the controls are first displayed. This can't be right. I have searched and none seems to have a similar problem so I thought I would ask here just to make sure. Here is a sample Hello world that shows the problem with the color picker (takes ~ 3 seconds to show pallet when clicked).
public class HelloWorld extends Application
{
@Override
public void start(Stage primaryStage) {
StackPane root = new StackPane();
ColorPicker cp = new ColorPicker();
root.getChildren().add(cp);

View Replies View RelatedI work on SSH for creating a external tool to manage remote OS.
I find out the JSch library and i create the java GUI project as jar application, and worked for me very well. (i am working on Netbeans ).
I introduce the JSch library with Netbeans as follow. Right click on the Project-> Properties -> Libraries ->Compile ->Add JAR/Folder.
After that i try to transform the project to applet in order to work it form web server.
I made the transformation in all the code.
When i run the applet through the Netbeans it worked for me. When i build the project to create the jar file.
I create a folder with the my.jar file, index.html, a folder named (lib) which contains the jsch-0.1.50.jar file.
Then try to run the index.html, the GUI appear but cannot connect to the remote with the SSH, and does not give any error.
I think that the problem is that my.jar cannot communicate with the jsch-0.1.50.jar.
Why the project runs trough the Netbeans an does not run when i call it from the next html code.

I have written a code to download .csv file with records from DB.
To download records i am uploading a .CSV file containing telephone number.
After downloading the .CSV file page is not getting refreshed.
Below is the code snippet i am using,where i am setting response content type as test/csv.
ServletOutputStream op = resp.getOutputStream();
// Set content type of output
resp.setContentType("text/csv");
resp.setHeader("Content-Disposition", "attachment; filename="test"");
op.flush();
op.close();
How that page will get refreshed after csv file download or after response.
I get this error when I load a HTML page with WebEngine. The HTML is getting generated by an own (Java-)ServerSocket. How can I figure out where the problem is? I can load the HTML file successfully when loading the(same) generated HTML file from the local filesystem. Maybe the http headers causing these problems ? On the other hand I can load the page without problems in Firefox. How to get more information ?
View Replies View RelatedThe project is to develop the game Translate the Word .... It is asking user to translate a word proposed to and check if the input response is correct. At the end of the game score will be calculated and displayed.
Game Play :
1 - Ask the user to specify , through the console , its name and the number of words to offer . It is up to you to handle exceptions (eg number of words greater than the number you provided )
2 - Recover user response ( the word translated ) and check whether to continue . (eg you want to continue (y / n)) after each proposal.
3 - compare the response of the user with that which is preset for the word in question .
4 - Show the score at the end ( or at the breakpoint ) .
5 - Save the file in a user name , the score , the number of questions and the start date and end of the game played .
Some notes to consider :
1 - The language (eg, English - French , English - Arabic , etc. . ): It is up to you to specify the language adopted in the game and inform the user of your choice.
2 - The word bank to offer : It is up to you to develop the appropriate means to get the words to propose to the user. That said , the words and their translations can be retrieved :
a. a TXT file
b . an XML file . ( Tutorials DOM and SAX )
c . CSV file ( OpenCSV Tutorial )
d. a database ( Tutorial Access)
e . through APIs (eg Wordnet and google translate etc . ) .
f . a combination of the previous options a, bc , d and / or e . (eg words stored in a txt file and answers retrieved from the api google translate)
g . etc. .
Examples of files and databases are attached to the project statement . You will need to add one or more external libraries to your project. Click here for details on adding external libraries to Netbeans .
3 - A user will be associated with the question score if he can translate the word correctly. The score for each question can be calculated based on the number of words / questions to be proposed .
Development : In this project you will need at least a class called Question to encapsulate the word and its translations and provide all necessary methods to manipulate the object type Question.
An interface called IParser to make extensible project. Any class that implements IParser is a parser file (XML , TXT , CSV , etc.). / Database. In your project there will be a single class that implements IParser and will be used to retrieve words and their translations.
Add the ability to store the questions and answers of the user on the hard disk. Make the class Serializable Question
I'm trying to work out how to get a string from a servlet in to the JSP, The code I thought would work was as follows.
request.getSession().setAttribute("test", "this is a test");
request.getRequestDispatcher("C:myjsp.jsp").forward(request, response);
<%
String s1 = (String) session.getAttribute("test");
%>
<%= s1 %>
This is returning null ...

I am new in XSLT and I started to support an application which has the servlet below. Which are the patterns in this servlet related to XSLT? Beyond the basic methods get and post, I didn't understand the purpose of too many methods. Obviously I can debug but I can figure out every purpose because it is not clean code: at least when I compare with much more straight forward servlets that I have supported. It seems that who has developed this application has used some common practice of wrapping DOM and SAX methods.
