Java Servlet :: How To Create Files On Server (online)

Jun 5, 2013

I'm making a website with articles (like a blog). I have a webpage called admin.html where you insert the data of the article (title, post etc).

Admin.html calls to a servlet and this sends the information to a SQL Database and it stores and my index.jsp calls to database and show the articles.

This works perfect, and a non-programmer can insert new articles. The problem is that I need to create an .html file for every article/post and save it into my server online.

For example if I create "CoolArticle", I need the file "CoolArticle.html" and save it in my hosting.

How I can do it? I never have seen examples online, all were local, so I can't continue.

Java Servlet :: How Is Session Maintained In Application Server

Aug 3, 2012

How is session maintained in the application server, internally what happens when the user has logged in ? We create a session and store the user details which will be stored in the session object in the server with a unique sessionID which will be validated when the same user login the system again? But how exactly the session is maintained in the Server internally?

An Error Occurred While Shelling Out To Javac - Matlab

Jan 26, 2015

I am trying to extract a jar file from Matlab code using javac from Library Compiler (java package).

I have set JAVA_HOME to:

Java Code:

C:Program FilesJavajdk1.7.0_11 mh_sh_highlight_all('java');

and added to PATH:

Java Code:

C:Program FilesJavajdk1.7.0_11bin. mh_sh_highlight_all('java');

When I enter java -version in my console, I get java version jdk1.7.0_11 and running javac -version shows jdk1.7.0_11.

However, it seems that matlab could not find javac, thus, I am not able to compile my .m code into a .jar file. When I tried to compile .m code I got the following:

Java Code:

Error: An error occurred while shelling out to javac (error code = -1).
Unable to build executable.
Executing command: ""C:Program FilesJavajdk1.7.0_11binjavac" mh_sh_highlight_all('java');

This is the directory of my java bin folder and javac.exe exists : CProgram FilesJavajdk1.7.0_11binjavac.exe? What should I check in order to correctly link Matlab to Java?

Blackjack Program - Error Occurred During Initialization Of VM

May 21, 2014

I've been trying to finish this blackjack program I have been making for my programming class, however, there are a few bugs I can't seem to iron out. It's a pretty short program, it's just that I'm an idiot and can't figure basic stuff like this out. Specifically, when I try and run it, I get this error:

Error occurred during initialization of VM
java.lang.OutOfMemoryError: unable to create new native thread

Java Code:

import static java.lang.System.*;
import java.applet.Applet;
import java.util.Scanner;
import java.io.*;
import java.util.Random;
import java.util.Date;

[Code] .....

So, obviously I'm doing something horribly wrong.

Client Info On Server Side

Apr 6, 2014

I want to ask that, when a server listen to A port and it accepts a request from a client then the server accepts the request using accept method,but how does the server get the info about the client like wat is the port no and ip address of the client,I read a answer regarding this that Server never gets the port no of client only the ip address and it connects to client using a connection stream but as far I know from networking, a device must have the ip address and port no of the device it wants to connect to.

JSF :: Server-side State Saving

Nov 25, 2014

in my web.xml the.STATE_SAVING_METHOD setting is server

<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>server</param-value>
</context-param>

for measurement of application security isn't not allow to change this parameter to client , so the problem when I access for application and I open a new page via linker for print for example and I would access for my initial page to make change or modify my initial page it s no possible to make any modification because I have a empty bean , but if the state saving is a client I haven't a problem because a tree map is stored in client browser, so my version of JSF is 1.1.1 ,

Why Global Var Initialized With Static Method And Not By Other Static Global Var Declared After Its Usage

Jul 27, 2013

Take this:

class test
{
static int i=j;
static int j=10;
.....
 
this will give illegal forward reference ....
 
but this will compile successfully ..
 
class test
{
static int i=test1();
static test1()
{
return 20;
}
}
.....
 
plz assume we have main method in both cases ..
 
java would be loading all static members first and would be assigning default values .. and then will be running all the initializers from to bottom ..Why second case is a compile success and not first .. as in second also test1 method is declared after its usage ..

JSF :: What Tags Of Xhtml View Will Be Build As UIComponents In Server Side

Jun 8, 2014

In order to create an xhtml view:

1. All jsf tags like datatable, form, etc.. will generate UIComponents in server side, right?

2. All non JSF tags will not generate UIComponents in server side, right?

3. If you want something in a view that will be the same across users and requests, I mean, It will not change like a label tag, it doesn't make any sense to create it with a JSF tag in order to save memory in server side, right?
