I edited some lines from "[URL] ...." and saved it as html file; now if a friend want to do a search in Wikipedia for cats, the edited page should show up instead of original page.Is there a way to do this using java script.
View RepliesI want to know can we put the data of html file example
<html>
<body><applet code="classname" width="100" height="100">
</applet>
</body>
</html>
into my Applet's java file it can be done i have read it somewhere and have also implemented it ..... but now unable to memorize it
I have a JSP file at my local system and want to covert it to HTML through Java. Any reference link or tell me how to accomplish this?
View Replies View RelatedI just created an applet that I want to call from a html file.
The applet code looks like this (and works):
package jav12;
import java.awt.*;
import javax.swing.*;
public class Welcome extends JApplet {
public Welcome(){
}
public void init() {
getContentPane().add(new Label("Yessss it works",Label.CENTER));
[Code] ....
When I click on the html file the content of the page is blocked and the applet isn't loaded. What can I do to fix this. I think it has something to do with rights. This is a crosspost to JApplet content blocked
I need to convert a .txt file to html text, where the first line is changed to have < h1 > < /h1 > around it and the rest is wrapped in < p > < /p > so for example I read a .txt file that says:
chapter 1
this is a sentence
it would output:
<h1>chapter 1</h1>
<p>this is a sentence</p>
here is what I have so far and I cannot get anything to output.
FileInputStream filestream;
BufferedReader reader;
FileOutputStream output;
String firstline;
String body = "<p>";
String line;
[Code] ......
I compiled the applet, then put the applet in an HTML file using notepad and saved the html file in the right place for it to run correctly. The HTML file runs smoothly, but then it only shows the scrollbar part of my applet, and not the images or any text...
Why is This?????
Java Code:
import java.awt.*;
import java.applet.Applet;
import java.awt.event.*;
import javax.swing.ImageIcon;
public class Temperature_Convert extends Applet
implements AdjustmentListener {
private Image temp;
private Scrollbar bar;
private int old, newtemp = 0;

I have downloaded the target page's html-file successfully, but how can I find out WHEN that version had its latest update?
Here's how the page is downloaded:
public void dlPage(URL url) {
try {
br = new BufferedReader(new InputStreamReader(url.openStream()));
fileOut = new BufferedWriter(new FileWriter(url.getHost()+".html"));
while( (line=br.readLine() ) != null ) {
fileOut.write(line);
fileOut.write("

I was thinking of using URLConnection's method getLastModified() for comparison. But dont have a clue how to read it from this file. Am I perhaps solving the download-part incorrectly?
Snapshot downloaded file text:
I need to get the html in string when i hit the hit the jsp in servlets basically i need to put the output of jsp in pdf file when i hit one link i need to download that data in pdf file. I am using itextpdf.
Sample code
pResponse.setContentType("application/pdf");
((HttpServletResponse) pResponse).setHeader("Content-Disposition", "attachment; filename=report.pdf");
//Get the output stream for writing PDF object
OutputStream outStream=pResponse.getOutputStream();
ByteArrayOutputStream baosPDF = new ByteArrayOutputStream();

I need to convert the sample download.jsp to html so that i can parse
// XMLWorkerHelper.getInstance().parseXHtml(docWriter, document,new FileInputStream(jspPath),new FileInputStream(csspath) ,null ,new XMLWorkerFontProvider());
JFrame parentFrame = new JFrame();
File f12=new File("E:
ewfile.txt");
JFileChooser fileChooser = new JFileChooser();
fileChooser.setSelectedFile(f12);
fileChooser.setDialogTitle("Specify a file to save");
int userSelection = fileChooser.showSaveDialog(parentFrame);

I want to save selected text file as html file in target directory....
I know that the simple deployment using only applet tags inside HTML causes severe security restriction for the applet on the client side. but can this simple HTML file contains .jar files inside the applet tags instead of .class files.
View Replies View RelatedI inherited a navigation system which is like this:
index.jsp
homepage.jsp
When I click on the "view source" in the browser, I get two headers like this:

I know this is not good. I have inherited the nav system from someone else and I have a lot of complicated AJAX and JQuery going on inside my module. I am not sure how to resolve.
I have a secured Struts application in WebSphere that uses FORM j_security_check for authentication.There is also a Post Logon "filter" defined which runs some code after a login is processed.The extract from web.xml showing the login configuration and filter is as follows:
<login-config>
<auth-method>FORM</auth-method>
<realm-name>MyRealm</realm-name>
<form-login-config>
<form-login-page>/login.html</form-login-page>
<form-error-page>/error.html</form-error-page>
[code]....
If a user isn't logged into the application and they try to access one of the secured servlets, for example quotes.do, they are directed to the login page to enter their information.If they login successfully, they are then directed to quotes.do, rather than the default "welcome" page. Is there a setting in the web.xml or the post logon filter where I can force j_security_check to ALWAYS go to the default welcome page after a successful login?
I am trying to run a sign up page. The page is working properly and takes me to the login page when completed as it should. But when a field is left blank it is supposed to show an error message and keep them on the signup page, and it is not doing that. Sign Up Action:
<%
String field = "";
String message = "";
if ((request.getParameter("lastname") != null) &&
(request.getParameter("firstname") != null) &&
(request.getParameter("sadress") != null) &&
(request.getParameter("city") != null) &&
(request.getParameter("state") != null) &&

I am trying Single signon to a different application from my application. i use redirect to open the new URL in a separate window. MY single signon works well. But i am losing the session values in my application.
Because of this when i close the new window and click on any link in my application, i am getting error sicne all application objects inside session are reset to null. how to retain the session values after Redirect.
I have write a SSO class for Single Sign on But i am getting one issue i am using JSF2 for my web application...here is my SSO class :
public class ApplicationSSO implements SSO {
public String authenticateUser(RequestContext request) {
UmUsersList user = (UmUsersList) request.getSessionContext().getAttribute("USER");
return user.getUmulEmailId();
}
[Code] .....
As you can see i have write below line
JSFUtils.redirectPage("../login/Login.xhtml");
It mean if User null it will redirect to Login page but it is not working. How to solve the issue i am end up with
An error has occurred.
For detailed error information, please see the HTML source code, and contact the forum Administrator.

I have a JavaFX application with multiple scenes. In the application one scene plays the "master" role and the others are loaded according to actions . The issue i have is that i need to redirect all the PrintStream activity to a specific TextArea on the "master" scene, and by "all" i am meaning every PrintStream activity on every scene should be redirected to this specific TextArea . The code i am using on the "master" is :
Node node =primaryStage.getScene().lookup("#ShowInfo");
TextArea ta =(TextArea)node;
FXConsole console = FXConsole.getInstance(ta);
PrintStream ps = new PrintStream(console, true);
System.setOut(ps);
System.setErr(ps);
System.out.println("Test");
I am using the Singleton pattern for the rest of the scenes :
FXConsole console = FXConsole.getInstance(null);
PrintStream ps = new PrintStream(console, true);
System.setOut(ps);
System.setErr(ps);
System.out.print("Hello There");
ps.close();
The issue is that i don't like this implementation ....
I use the jsch libraries to create a SHH connection to a remote linux machine. In the next code, given from a tutorial of the JSCH creator, you can see it is implemented shell communication, it is a direct communication from a cmd window. You enter a command from the cmd window and you get aback the results in the cmd window.
Java Code:
String user = "username";
String host = "hostname";
ession session=jsch.getSession(user, host, 22);
String passwd = JOptionPane.showInputDialog("Enter password");
session.setPassword(passwd);
Channel channel=session.openChannel("shell");
session.connect();
channel.setInputStream(System.in);
channel.setOutputStream(System.out); mh_sh_highlight_all('java');
How i can redirect the next two lines to jTextField1 and jTextField2. To give an example i want to sen the command from the jTextField1 and to get the results from the jTextField2.
Java Code:
channel.setInputStream(System.in);
channel.setOutputStream(System.out); mh_sh_highlight_all('java');
I have a simple application ( only 2 JSPs files and one servlet the main components the whole webapp directory is attached ), I am using security constraint to redirect the user to HTTPS instead of HTTP when he submit from first page to the second page.
The problem is when the user submit the first page I get the error HTTP Status 405 - HTTP method GET is not supported by this URL although I m using only POST.
I have traced the firefox browser using httpfox and the result was the first HTTP request was done using POST correctly but after redirect the browser send GET.
This problem appears with FireFOx and IE but doesnot appear with google chrome.

I have a JavaFX application with multiple scenes. In this applications one scene plays the role of "master" role and the others are loaded according to actions on the "master" scene(buttons,menu items)
The issue is that i need to redirect all the PrintStream activity to a specific TextArea on the "master" scene...
So everything that normally goes to the console to get redirected to that specific TextArea and this should be global,on every scene that is outputting something it should displayed on the specific TextArea on the "master" scene
The code i am using right now on the "master" scene is :
Node node =primaryStage.getScene().lookup("#ShowInfo");
TextArea ta =(TextArea)node;
FXConsole console = FXConsole.getInstance(ta);
PrintStream ps = new PrintStream(console, true);
System.setOut(ps);
System.setErr(ps);
System.out.println("Test");
For the rest of the scenes i am using the Singleton Pattern to keep the pointing to the Specific TextArea
FXConsole console = FXConsole.getInstance(null);
PrintStream ps = new PrintStream(console, true);
System.setOut(ps);
System.setErr(ps);
System.out.print("Hello There");
ps.close();
The issue is that i don't like this implementation so ...is there a better solution
I have a scenario here where the JSF lifecycle is not getting invoked. I have a filter, whose responsibility is to filter only authorized requests.the code of the filter is given below
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest)request;
HttpServletResponse httpResponse = (HttpServletResponse)response;
[code]....
now in the else block i am filtering the unauthorized requests, and sending them back to the Login.xhtml page of the application.The problem i am encountering here is that, the images and styles associated with the page are not getting loaded, what i am thinking is that when i am using redirect or forward, the FacesServlet is not getting called, and it is directly going to Login page i.e. no Lifecyle is being called.how to Filter the requests and at same time not lose the styles?

I am using a command button to post a form to backing bean method. At the end of that method I am attempting to redirect to an external site after setting various options in the response. I get an IllegalState Exception because of the redirect.

I am reading input from a file that has following information:
line 1 = numbers of integers in array,
line 2 = elements in array1,
line 3 = elements in array2.
These lines constitute a test case. There are 1000 test cases in the input file.
So basically, I read the length of arrays, populate the arrays by reading from the file.
The code is below ( I have not included reading input code):
while(test_case<1000){
if (count == 1){ //count keeps track of lines in input file
vec_length = Integer.parseInt (tokenizer.nextToken());
count++;
continue;
}
if (count == 2){ //populates array1
vector1 = new int[vec_length];
for (int i = 0; i < vector1.length; i++)
vector1[i] = Integer.parseInt (tokenizer.nextToken());
count++;
continue;
}
Array2 is populated using the same as above code. However when I use the following code:
for (int i=0; i<vec_length; i++)
temp += vector1[i]*vector2[i];
I get " local variable vector1 and vector2 have not been initialized error". But both arrays have been initialized in the if{} block. Is it because initialization was local to if block?
As a studyproject I'm currently writing a class the allows me to get al fun dates (like when eastern is in a given year, what day a given date has, calculate the date of tomorrow).
While working on the following method:
public String getNextDate (int day, int month, int year) {
String nextDate;
int nextDay = getNextDay(day, month, year);
int nextMonth = getNextMonth (day, month, year);
int nextYear = getNextYear (day, month, year);
return nextDate = "the day after " + month +"-" + day + "-" + year + " is " +
nextMonth + "-" + nextDay + "-" + nextYear + ".";
}
I get a notion in my lovely IDE (eclipse) reminding me I'm not using nextDate ("The value of the local variable nextDate is not used"). But I feel I really do use nextDay here. So either I'm making a coding(style) mistake giving me this notion or I should just ignore this notion.
you can also refer this link Local variables in java?Local variables in java?To meet temporary requirements of the programmers some times..we have to create variables inside method or bock or constructor such type of variables are called as Local Variables.
----> Local variables also known as stack variables or automatic variables or temporary variables
----> Local variables will be stored inside Stack.
-----> The local variables will be created while executing the block
in which we declared it and destroyed once the block completed. Hence the scope of local variables is exactly same as the block in which we declared it.
