Displaying All Variable In HTML?
Jan 6, 2015
i have got an array which has come from a text file.
Parts of the array have been placed into a string.
So string one will have about 50 different values which I am able to print into the console using System.out.println("FirstString"); This prints all of the variables from the array so I end up with 50 words.
I am now trying to get this into a HTML document.
I have correctly done this and I get some out put when the webpage opens.
My problem is that I only have 1 work which is displayed.

Im new to jsp. I have the following html in my jsp
<select name="job" id="job">
<option value="Booked">Booked</option>
<option value="Assigned">Assigned</option>
<option value="In Process">In Process</option>
<option value="Completed">Completed</option>
</select>
How do I assign job in the scriplet like how we do <% String job = request.getParameter("job")%> but on the same page? <% String job = request. getParameter("job")%> returns null value.

Given the case I have an object which is assigned only once. What is the difference in doing:
public class MyClass {
private MyObj obj = new MyObj("Hello world");
private MyClass(){}
//...
}
and
public class MyClass {
private MyObj obj;
private MyClass(){
obj = new MyObj("Hello world");
}
//...
}
Is there a difference in performance or usability? (Given also the case there are no static calls expected) ....

The term "Local variable" is related to scope. That is a local variable is one which is defined in a certain block of code, and its scope is confined inside that block of code.And a "Member variable" is simple an instance variable.
I read in a discussion forum that when local variables are declared (example code below), their name reservation takes place in memory but they are not automatically initialized to anything. On the other hand, when member variables are declared, they are automatically initialized to null by default.
Java Code: public void myFunction () {
int [] myInt; // A local, member variable (because "static" keyword is not there) declared
} mh_sh_highlight_all('java');
So it seems that they are comparing local variables and member variables. While I think a member variable can also be be local in a block of code, isn't it?

Given a reference variable : Car c1 = new Car();
when we create another variable and set it equal to the first : Car c2 = c1;
we're pointing c2 at the same car object that c1 points to (as opposed to pointing c2 at c1, which in turn points at the car). So if we have code like,
Car c1 = new Car();
Car[] cA = {c1, c1, c1, c1};
are we doing the same? Are we creating four *new* reference variables, each of which points at the same car (again as opposed to pointing them at c1 itself)? I think so, but want to make sure I'm understanding this correctly.

I have a JFrame jf and JPanel jp on it. jp has five TextFields named cel1, cel2.. cel5. I wish to construct a String Cel + for loop index and run a for loop to reset the values of all the text fields using a single statement such as cel1.SetText("abc"). Similar things can be done in foxfro. How does one do it in java?

I am creating a search module page. It has many input ext field and a search button.
On my jsp, I have the following:
<label>Reference ID:
<input id="referenceID"
name="referenceID"
type="text"
value="<c:out value="${transaction.refId}" />"/>
</label>
On my servlet, I have the following (code fragment):
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Transaction transaction = new Transaction();
transaction.setRefId(request.getParameter("referenceID")== null || request.getParameter("referenceID")== "" ?null:Long.parseLong(request.getParameter("referenceID")));
request.setAttribute("transaction ", transaction );
}
Is there any alternative on executing request.getParameter on the id's of input text in order to set it on the Transaction bean so that the values will display on the user when the page reloads?

I have a large product with many maven projects, all of which can be hierarchically tracked back to the same parent. The projects have javadocs and whatnot.
Icommand line instructions (Windows 7) to generate the full API documents html on my local machine (of all the projects together). If there is a maven command for doing this from the CMD, more the better.

I do not think this is possible, but I'd like to confirm. If I have an HTML page that has an embedded Java applet, and that applet in turn renders an HTML document (within the applet window), is the HTML *within* the applet part of / accessible through the DOM for the parent page?

Is there anything wrong with writing JSP tags in psuedo-HTML? I've been writing tags in XHTML, but it would seem that XHTML could not be compliant with both an XHTML standard and the HTML5 standard.

My problem is my teacher told me that i have to add a radiobutton on html. According to radiobutton servlet has to choose write parameters on DB or File. And he wants me to add a method to do this work.
1)Get Parameters
2)Choose to write DB or File according to parameters
3)if it is DB create connection and do writing process
4)if it is file create file and do writing process.
Second piece of code should be removed. İnstead of this i have to use a single method. But i don't know how to do this(not writing code). Should i use another servlet or a class...
package GB;
import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
[Code] ....

I have a requirement to do the following;
-Allow users to upload a zip containing an html document + associated images.
-Allow emails to be sent using the contents of that upload as the html of an email.
That's fine. What I'm finding to be tricky is a requirement to show a preview of the html.These files will be accessible to the file system of the tomcat web server, but how can I effectively serve them into an iframe?

You basically paste a url Into a textarea and choose an Image for the link.The Image link Is then appended to a html file.
I'd like to put everything In a single jar file but I'm not sure what to do so the user can access the html file.
The only two options I can think of are:
a) create the html document on the fly when the jar runs.
b) Is to run a bat command when the jar Is executed that will extract the jar files.
The user can either choose from a number of Images In the logos folder for common websites or add new Images. Since the folder isn't empty , It seems like extracting the jar files Is necessary.

I would like to make a database using HTML and Java. I already made something like this using swing. I am just looking for some pointers here. I just started looking into Java Play 2 and I have a feeling this is what I am looking for. JavaEE is very complicated and I have read that it is being phased out. What is your opinion on this?
I want to make a static HTML page and put it on my home network and treat one of my computers as the sever accessing mySQL.

I am having a difficult time trying to get results from the code below. The purpose is for my program to insert the DHL tracking number in the tracking text box, and then for the program to "click" the search button and get the tracking results.
This is the code:
import com.gargoylesoftware.htmlunit.WebClient;
import java.io.*;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.html.HtmlInput;
import com.gargoylesoftware.htmlunit.html.HtmlSubmitInput;
import java.net.*;
public class DHL {
[Code]...
These are the results I am getting in the console (in red), which look like an error:
Apr 23, 2015 7:55:49 PM com.gargoylesoftware.htmlunit.javascript.host.html.HTMLElement addbehavior
WARNING: Unimplemented behavior: #default#userdata
Exception in thread "main" com.gargoylesoftware.htmlunit.ElementNotFoundException: elementName=[*] attributeName=[name] attributeValue=[sbtc]
at com.gargoylesoftware.htmlunit.html.HtmlPage.getElementByName(HtmlPage.java:1747)
at htmlTest.main(htmlTest.java:17)
I just cannot figure it out for the life of me. Also, is there a community that focuses on HTML Unit?
