We need to process (read and parse) big xml files (500 Mo to 1 or 2 Go). What's the best framework or Java library to use for this requirement ? Then what's a good OXM (in this case xml to object mapping) solution for this kind of file ?
View RepliesWhen I map my servlet to the ROOT of the site, the javascript, CSS and image files are not served. The conversation between the server and browser shows the files are being sent, but they are not rendered in the browser. This happens in both Firefox and Chrome.
If I change the mapping to anything other than the root, such as /x/, everything works as it should.

I need to process 10000 xml files and verify and insert the data into database. I am loading all the files in the file object and iterating one by one. I am getting the memory issue. How to handle this?
View Replies View RelatedI've been trying to write a program for some time now, but im encountering problems while trying to complete it. The program has a student class and a course class (set up with some info about the class, like #, professor name, course title, course time). Now, i have a text file in the workspace, and i have to import the data from the textfile, and thats just what i did, but then there is an option which allows the user to delete a course only by inputing the course number, and when he does that, the program outputs the course's name, and confirms the deletion of the course (From the student's record, i created a vector for that and imported all the courses from the text file). But how can i let the program know what's the name of the course when the user inputs the course number ???
When the data is read from the file, objects should be created and added to the student's course record. <- i think here's where i messed up ? i imported the data, but how can i actually make them objects before adding them into the vector ?
PHP Code:
public static void main(String[] args) throws IOException
{
Scanner scan = new Scanner(System.in);
Vector Record = new Vector();
try {FileReader filereader = new FileReader("CLASSES.txt");
BufferedReader bufferedreader = new BufferedReader(filereader);
String test = "";
while(test != null)
{
Record.addElement(test);
test = bufferedreader.readLine();
} mh_sh_highlight_all('php');
I have a project in java that asks me to load some information from previous object files and add new objects to them afterwards. I created the files, but when I close the program and search for the previous information that should've been saved in the object file , it return nothing.
Here is the code.
Add method:
public boolean addUser (User u){
users[Ucount]=u;
Ucount++;
return true;
}
The save method:
public void saveUser (){
try{
FileOutputStream FOS = new FileOutputStream("User.txt", true);
ObjectOutputStream OOS = new ObjectOutputStream (FOS);
[Code] ....
The read method:
public void readUser (){
try{
FileInputStream FIS = new FileInputStream ("User.txt");
ObjectInputStream OIS = new ObjectInputStream (FIS);
for (int i=0;i<Ucount;i++){
[Code] ....
*Note: When I open the object file I could see that the information are actually there, so I think there's a problem with the read method I'm not sure what it is.
I have a servlet that is not mapping to my URL:
<servlet-mapping>
<servlet-name>view</servlet-name>
<url-pattern>/View/*</url-pattern>
</servlet-mapping>
When I try to call the Servlet from a JSP:
<a href="/View/viewFlow?V1">V1</a>
The resulting link is [URL].... It's bypassing the project name. The link should be [URL]...
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter pw = response.getWriter();
String connectionURL = "jdbc:mysql://localhost:3306/userdb";// userdb is the database
Connection connection;
[Code] .....
When casting a char which is read from a file to an int, can i assume that the mapping used will be ASCII? I've learned that unicode uses ASCII mappings for the characters that overlap.
Are there any other possibilities for int values of one character? I still have trouble understanding character encodings.
I am writing a program where I need to split an array of full names into First names and Surnames, using mapping. However, I am struggling how to split it up... and my First Names and Surnames list are both just displaying the full name.
public static void main(String[] args) {
String[] names;
names = new String[8];
Scanner s = new Scanner(System.in);
for (int i = 0; i < names.length; i++) {
System.out.println("Enter full student name:");
[Code] ....
I have this mapping:
<servlet>
<servlet-name>wsdl</servlet-name>
<jsp-file>/wsdl/bankconnect.html</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>wsdl</servlet-name>
<url-pattern>/wsdl</url-pattern>
</servlet-mapping>
And this works fine: URL....The war file is deployed under the context root /bankconnect/ I want to make a servlet mapping, before the context root "i still want the context root bankconnect". URL....
I'm working on a project and I'm just about to implement different stages (menus etc). The program is opened in an intro stage that just renders a text (slick, Unicode font) looking like this:
After switching to a different stage hat uses shadow mapping and then back to the intro stage it looks like this:
I've found that removing the line:
glCopyTexImage2D(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT, 0, 0, shadowMapWidth, shadowMapHeight, 0);
solves the problem but then the shadow mapping isn't working.
I'm looking for a working example of shadow mapping with java code using shaders. There are so many c++ or c tutorials out there but i haven't managed to rewrite them since I'm too bad in c/c++. I've been trying to implement this a long time but can't get the hang of it. Any example out there? Preferably as sstripped down as possible except for the shadow mapping.

We generally use [URL] ..... for running web applications.
What I want is to access my web app using something like this: [URL] ....
How to achieve this? Actually what i want to ask is that how URL like WWW.example.com is mapped to web applications? Assuming that i am using tomcat server.
I have downloaded and testing these two mapping libraries. I wrote a program which has 100000 iterations and maps the beans of the same class:
public class IntBean {
@JMap
private int int1;
@JMap
private int int2;
[Code] ....
Mappers are created BEFORE iterations start:
private JMapper jmapper = new JMapper(IntBean.class, IntBean.class);
private MapperFactory orikaFactory = new DefaultMapperFactory.Builder().build();
private MapperFacade orikaFacade = null;
orikaFactory.registerClassMap(orikaFactory.classMap(IntBean.class,IntBean.class).byDefault().toClassMap()); orikaFacade = orikaFactory.getMapperFacade();
What is in each iteration:this.orikaFacade.map(a1, a2);
or
a2 = (A) this.jmapper2.getDestination(a1);
I know, that Orika and Jmapper are great libraries from Google and they use reflection in a different way than for example Dozer, which is much slower, they se reflection to generete code somehow..
I have 3 questions:
1) How they work - when the code is generated, during maven build, in runtime - everytime when I create mapper in code? Are they change class code byte dynamically?
2) Why there is this speed difference that I noticed?
3) Which library would you choose and why? Both have the same capabilities? Why both come from Google? Why Google didnt develop Orika and created Jmapper instead?
So, i got the following code:
@Path("{bill-id}/request")
@Path("{user-id}")
and the following pattern
myhost/c15a856/request
somehow, the container always decides to match it to @Path("{user-id}"). How do I resolve this

I created a main class called X and two Y and Z classes.
Y and Z implements Runnable classes.
class X contains a static array A that can be accessed in Y and Z.
The Run () method of the class Y reads an input file and populates the vector A.
The Run () method of the Z class uses data stored into the vector A to process some data.
The objective of using threads in this problem is: as the vector A is filled in the Run () method of class Y, the Run () method of the class Z will processing the received values in the vector A.
to do this I did the following calls in the main method of class X:
ObjectY y = new Y ();
Thready thread = new Thread (objectY);
threadY.start ();
ObjectZ new Z = Z ();
Threadz thread = new Thread (objectZ);
threadZ.start ();
is that correct? I'm getting the expected results, but dont know if the code is parallelized in fact.

I am working on a management gui for a program. I have implemented the start server button. But now I need to get something working so that when I press stop server the javaw.exe process which is running the the other jar file is stopped and ended.
The gui is going to be using a javaw.exe as well and I don't want to end the entire thing.
I just want to end the javaw.exe process that is running the other jar file.
This is my code for starting it:
JButton btnNewButton_2 = new JButton("Start Server");
btnNewButton_2.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
Runtime rt = Runtime.getRuntime();
try {
Process pr = rt.exec("java -jar DEDServer_release.jar");
[Code] ....
I just need to figure out what to do to stop it now.
I am looking for a way to have a Servlet (my container is Tomcat) calling a JSP file and processing it in order to retrieve the generated HTML. The compete scenario:
I have virtual shop and whenever a purchase is being carried out, the customer is redirected to a Servlet that post-processes the purchase (list of the items, etc.)
Among all these, the Servlet is also supposed to send me an email about the new purchase. I would like to have nice designed HTML mail and not just a simple plain text notification. I thought of having a designated JSP as a view, and it will only be available from the Servlet container, for this purpose. One way is having the Servlet create an HTTPClient (or any other method of network communication) to my own host and ask for the JSP.
I wonder if there is a simpler way to ask my own container to process a JSP, since I am not really making a request to an outside web application. Something like getServletContext.processAndReturnJsp("mail.jsp")
BTW, if you think my approach is too cumbersome to fill an email with HTML code, it would be great to know of a simpler way.
