I am trying to hit the service which has been generated using apache cxf 3.0, I have generated the client using axis2 wsdl2java and whenever I tried to hit the service am getting as
"exception from OLB Service:org.xml.sax.SAXParseException: Content is not allowed in prolog."
Not sure about the cause of the issue. We have made interceptors on the server side to verify whether there is any special characters associated, but there are no such characters from provider.

I have to store data I've pulled from the web i wanted to do this by storing it in a database but after looking at some tutorials i'm not sure if its possible as the databases don't seem to run with the application but instead run as an independent entity.if its possible to have a database in the java application so it runs when the application runs.

I have a java application which uses Google Maps to analyze the traffic condition. But sometimes it can be run and work properly, sometimes not. On some computers on which there is installed java, the program can be run, and on some, again with installed java (jre), exactly the same version, the program can not be run. For example the application first run well on my desktop computer, connected in a LAN, and then stopped working well when run. But when I use laptop which uses the WiFi and run the same computer using VMWare, if I connect to the desktop on which the program can not be run, on the laptop the same program can be run well, in the same room, but using the Wifi.

At our company we run a third-party Java-based GUI application on one of our Linux server machine, displaying the application to our local Windows work stations using the Cygwin X Server.We noticed a few problems with a new version of this application and was able to narrow it down to the following conditions:
1. Java Swing application running on a UNIX host;
2. Java used is 1.6 (problem not noticed when using Java 1.5)
3. Displaying to Cygwin X server (I've heard other windows-based X servers have the same issue, but I don't have access to any others at this time).
If we run the application natively on Windows, I'm told if the application runs on the Linux host and displays natively to that machine's display there are no problems (although I'm not able to verify this myself).The problems are:
1. Any new frame/dialog is opened in the geographic center of the dual displays, rather than in the middle of one or the other;
2. Any attempt to drag the window to a different location on the display seems to work, but as soon as you let go of the drag, the window snaps back to the original location. This only happens the first time you try to move each window.
3. Drop-down controls (JComboBox, for example) just close back up as soon as you click on them. If you click and drag the mouse to attempt to make a selection, no selection can be made.
Are these known problems using 1.6 on UNIX displaying to Windows-based X Servers?
The only real problem is number 3. I expect that if I put more work into the window placement, I should be able to get past number 1. Number 2 is just a minor annoyance.The following is a simple Java Swing application which when run in the correct environment will exhibit the problems.
import java.awt.EventQueue;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

I am trying to put together an encryption/decryption application that will essentially accept a sentence that is submitted, and spit out the encrypted version and then switch it back to the correct sentence. I have been told to nest my information in the class (rather than the main), but am having difficulty actually understanding how to do this. The error that Eclipse is throwing me is also that it "could not find the main class." Here is my code:
import java.util.Arrays;
import java.util.Random;
public class encryptingWords {
public static void main(String[] args) {
final int ALPHASIZE = 26;
final char[] Lalpha =

We have developed a java application, whose primary objective is to read a file(input file), process it and convert it into set of output files. (I have given a generic description of our solution, to avoid irrelevant details).
This program works perfectly fine when the input file is of 4 GB, with memory settings of -Xms4096m -Xmx16384m in a 32 GB RAM
Now we need to run our application with the input file of size 130 GB.
We used a linux box with 250GB RAM and with memory setting of -Xms40g -Xmx200g (also tried couple of other variations) to run the application and hit OutOfMemory Exception.
At this stage of our project it's very hard to consider redesigning the code to accommodate hadoop ( or someother large scale data processing framework), also the current hardware configuration which we can afford is 250GB of RAM.
Any ways to avoid OutOfMemory Exceptions, what is the general practice when developing these kind of applications.?

I was giving a quick skim to some tutorials on the internet where I have found the exception that is handled is also declared in the throws clause of the method wrapping the try-catch block. For a code representation consider the following:
public void methodName() throws IOException {
try {
...
} catch (IOException ex) {
.... TODO handle exception
}
}

I am new to work on JNLP program. I have created a SWING program, JNLP file when i deploy the ear file i am getting 404 error. Please find the steps in details.
1.Created a dynamic web project JWStartProject in eclipse
2.Create a HelloWorld.java class under default package.
import javax.swing.*;
public class HelloWorld extends JFrame {
private static final long serialVersionUID = 4968624166243565348L;
private JLabel label = new JLabel("Hello Java Web START!");
public HelloWorld() {
super("Jave Web Start Example");
this.setSize(350, 200);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
this.setLayout(null);
[Code] ....
Now I exported this project as JWStartProject.war contains following code.
Created Server in Websphere Admin console
Deployed this war file under the server and started.
I have added MIME types also.
I am unable to launch the application. I am getting 404 errors. May I know where I went wrong?

Right, so I got this program. It takes input from the user and assigns it to fields on an object. But, it's meant to check the users input. If the user enters bad input, it's supposed to throw this exception. For each of these exceptions, theres a class specifically for it.
public class PayrollDemo
{
public static void main(String[] args)
{
Payroll pr = new Payroll ("Test Name", 234);
System.out.println("Current Employee Information.
");
System.out.println("Name: " + pr.getName());
System.out.println("ID: " + pr.getID());
System.out.println("Hourly Pay Rate: " + pr.getHourlyPayRate());
[Code] ....
And this is the exception class.
public class InvalidNameException extends Exception
{
/**
No-arg constructor
*/
public InvalidNameException()
{
super("Invalid name");
}
}
PayrollDemo.java:43: error: cannot find symbol
InvalidNameException.InvalidNameException();
^
symbol: method InvalidNameException()
location: class InvalidNameException
1 error
It's just meant to tell the user that they entered an invalid value, which would mean if they entered an empty string instead of a name.

I don't seem to be hitting my RESTful webservices. I am using Hibernate and checked and all my entity classes are working. I've even retrieved data from the database but I cannot hit the web service. I am using Tomcat 7 and Eclipse IDE.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>HibEx1</groupId>
<artifactId>HibEx1</artifactId>
[Code] .....
I have a web xml but there is really nothing in it. The url i am wanting to hit is [URL] ..... Is this a correct URL?
I also tried changing my Path to "/service" and that did not work either. I am getting a Http Status 404 "The requested resource is not available.

I'm developing a SOAP client and have used wsimport to generate the classes, etc. and all is going pretty well, but the server requires several headers that I've been coding up manually, specifically wise:Security and o:Security blocks. While this is a valid approach, I think I'm probably doing things the hard way and I know .NET (SOAP being an MS standard originally) has some really powerful code to generate these headers. Does java have any similar counterparts? As an example, I'm writing code like the following:
SOAPElement token = securityElement.addChildElement("UsernameToken", "o");
token.addAttribute(soapFactory.createName("u:Id"), "UsernameToken-1");
SOAPElement userToken = token.addChildElement("Username", "o");
userToken.addTextNode(user);
