I need to execute a perl file from a resource folder, So that i can able to run the perl file after changing the project to a jar file. And also i need to pass an argument also.
I am validating an xml file using XQuery in Java using XQJ API. When the query is triggered it is giving the ClassNotFoundException for orai18n.text.OraCollator. I have placed the orai18n-collation.jar file in MANIFEST.MF file and it is loaded in to the class path.
Not sure on why it is giving the exception.
The JDK i am using JDK1.7 and application server is weblogic.
Picked up _JAVA_OPTIONS: -Xmx10g -XX:MaxPermSize=10g
can get the values for 1.0

I was doing coding exercise from a book ('OCP Java SE 6 - Practice Exams' by Kathy Sierra and Bert Bates). I came to a question that told to demonstrate the difference between 'default' and 'protected' access rules by creating/making a directory structure and putting a couple of classes in different packages.
For this, I made a total of four classes, out of which, three classes are-Car, TestingCars, CarDimensions. (The fourth is not yet used in testing code till now, so, I am giving only the other three classes.) Their coding is given below.
Out of these classes, the classes- TestingCars and Car - are in a directory (say, FolderName). And, the class- CarDimensions is in FolderName's sub-folder.
The class 'CarDimensions' is public (and its components too are public). And, I am testing all the classes from the class- 'TestingCars'. But, this class (TestingCars) is not able to find the public class- 'CarDimensions' which is in its sub-folder and gives two 'Cannot find symbol' errors citing the class-CarDimensions. Also, If all three classes are put in one single directory, the programs work, without any error.
Coding: Class TestingCars:class TestingCars { public static void main(String[] args) { Car c = new Car(); c.setType("FourWheeler");
[Code]....
I could not find why the public class- CarDimensions- is not getting found by the TestingCars class.
Within my program I allow users to write their own code to be executed. I then save that code in a .java file and then compile. This gives me a .java file and a .class file within the same package in the src folder. However, the compilation process also creates a .class file in the build folder. When the user edits their code and then re-runs it, the .class file in the build folder does not get updated with the new data, but the .class in the src folder does.
What I want to do is to execute the .class file in the src folder and not the build folder. So far I have the following method, but that somehow refers to the .class file in the build folder:
public void runMethod(String packageFilePath, String className){ try{ URI fileURI = new URI("file:/src/uk/learningAid/UserInputs/"); URL url = fileURI.toURL(); URL[] urls = new URL[]{url};
Where can I learn or how can I, being the most efficient way known to do so, create a folder outside my JAR file with the java source code, this then will copy YAML documents from my JAR file to that folder, then I need to read the YAML documents some way. I'm making an addon for a game, I am using an API that allows you to make a config.yml easily, and add and read entries from it, but I've read that I need to make my own methods to be able to create additional YAML documents.
I don't exactly know what to type in google to perhaps find such a page, but I did try to find a tutorial page about this or something and couldn't.
I've partially figured out how to create a folder, but I have a problem, how can I RETURN one directory to make the folder, I don't want to make the folder in the JAR file I want to make it just outside the Jar file in the same folder that the Jar file is at.
Means like in php we can install xampp and there for a new app we need to create a folder in htdocs folder...and after that , that folder works like a app.
I have observed a strange behavior in my system. whenever i installed jdk1.8.0_11, the issue is that, unknowingly the 'Bin' folder which is underneath 'C:Program FilesJavajdk1.8.0_11' is emptied. When and how it is emptied i wouldn't be knowing. I have to download the entire jdk every time in order to have Bin folder content every time.
I am using my office laptop, Is that the problem? I mean office IT department have any control on this? If so , what can i do to over come this problem?
I am currently using the following Rally API Java code(below...in Java 1.7) to create an object and attach a file to it. This code works fine. But I need the code to be a little less specific and attach all files located under a folder (not just one file). How could one potentially rewrite this code (or use a different constructor/method) to accommodate such a thing? Also additional code how to narrow down results to all files with a creation date >= today.
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.

I am developing an web application with servlets and jsp. I have an issue to store images. I am storing images in folder and their relative path's in mysql database.
When I retrieve path from database then using <IMG> tag i have displayed image like:
I am working my way through "Head First Java" and typing the code in the book into Notepad++ as I go. In the first few chapters the code was simple and only had one class (main). Now the code has two or more classes. Originally I would compile the code in the Command Window by typing "javac" and the program's name. After it compiled I would execute the program by typing "java -classpath . " and the program's name. However, now when program has several classes I get the following error: Could not find or load main class. Below is a program I am having issues with... does it need to be saved as two separate files?
class DogTestDrive { public static void main (String [] args) { Dog one = new Dog(); one.size = 70; Dog two = new Dog(); two.size = 8;
I am not necessarily 'new' to java, however I have always used NetBeans so I am not entirely sure how to do what I need with the terminal commands. I am trying to execute a java jar file(which works perfectly on windows) on the Raspberri Pi, essentially debian linux.
As I mentioned previously, I have a java jar file which I can execute on windows, but it depends on three other libraries, namely RXTX, MySQL, and JSON. I am not positive how to compile this into a jar, or execute it in debian.
This was how I attempted to load two of those libraries, however the last line is the error I received.
Error: Could not find or load main class Automation_System.core.HAS
Specifically, the problem seems to be that I cannot use the -cp flag to indicate classpaths, and the -jar flag indicating I am executing a jar in the same command. I am not sure how to point the compiler to my main class HAS in the core package of the jar, and also to the libraries referenced.
I'm trying to make a statement of elapsed time print out after I've executed everything with a ThreadPoolExecutor. What happens is that instead of printing out after all the iterations within the for each loop are done, it prints out the elapsed statement in the middle of the iterations or even in the beginning of the whole execute() method. Here is my code:
package com.atem; import java.util.ArrayList; import java.util.List; import java.util.concurrent.Executors; import java.util.concurrent.ThreadPoolExecutor; public final class Example {
I've just installed the last Java kit JDK plus netbeans and I've done my first project in Java. It is running perfect from command line<but is is difficult to execute each time from there my tests> but I couldn't run the jar file from windows with double click he jar file even I've spent 3 hour on google to find different methods (registry modifying, control panel/program running in windows, a patch file etc, ) ....
I have been writing some loops for some days now. I'm just unable to predict the output for the following different piece of code even though I wrote 'em
public class Numbers { public static void main(String[] args) { int numbers[] = {1, 2, 3, 20, 80, 200}; for(int i = 0; i < numbers.length; i++) { System.out.println(numbers[i++] = 5); } } }
When a thread completes its execution, it will be destroyed.In Java thread pool implemenation, how does threads come back to ready state after executing the task.?
I have to implement a system where I have to do almost same processing on a jsp page. The slight differences on the present page is based on whether the current page came from page 1 or page 2. So how can I do this?
When i access to this page and save it as xml in realtime, the tags in xml file saved is empty while it is initialized and everything is working properly.
