Unable To Compile One Of Selenium WebDriver Files To Run From The Command Line
Apr 24, 2015I'm trying to compile one of my Selenium WebDriver .java files to run from the command line. Since it's just one file, I only need to compile the file into a .class file to run it from the cmd line. I don't need to make a .jar file.
The .java file runs fine inside Eclipse, so now I need to make it run from the windows command line.
I tried compiling it using
javac -classpath C:WDJarFilesselenium-server-standalone-2.42.2.jar TasksCreateAssignments.java
but got this error
TasksCreateAssignments.java:23: error: package org.apache.poi.hssf.usermodel does not exist
how can I can fix that?

JSP :: Unable To Compile Class

Unable To Compile Servlet Java File
Jan 20, 2015on my computer, i have configured the environment variables as
CATALINA_HOME : D:apache-tomcat-8.0.9-windows-x64apache-tomcat-8.0.9;
CLASSPATH : D:apache-tomcat-8.0.9-windows-x64apache-tomcat-8.0.9libservlet-api.jar;D:apache-tomcat-8.0.9-windows-x64apache-tomcat-8.0.9libjsp-api.jar;.;
JAVA_HOME : C:Program FilesJavajdk1.8.0_05
path : D:apache-tomcat-8.0.9-windows-x64apache-tomcat-8.0.9in
In reference to the book "Head First Servlets and JSP, 2nd edition", chapter-3(), page-81, the command to compile the servlet file to the desired location is
javac -classpath UsersertApplications2 omcatcommonlibservlet-api.jar:classes:. -d classes src/com/example/web/BeerSelect.java (from the Myprojects/beer-V1 directory)
Whereas I have written
javac -classpath D:apache-tomcat-8.0.9-windows-x64apache-tomcat-8.0.9libservlet-api.jar;classes;. -d classes src/com/example/web/BeerSelect.java
(from the same directory as can be confirmed from the attachment of screenshot of error). this code is in accordance to the location of the respective files in my system, in particular the servlet-api.jar file.
After doing this, my computer is showing the error : file not found.
How do I resolve this? Actually, I don't understand completely what this code is trying to accomplish.

RSA Encryption Decryption Using Separate Codes With GUI
Aug 16, 2014I am creating 2 different java codes for encryption and decryption separately based on RSA algorithm. The codes also involve swings for GUI. The problem with these codes are that my string is getting encrypted but after decrypting it,i do not get the string rather i get string of random numbers and alphabets. I am posting both the codes.
Encryption code:
import java.math.BigInteger;
import java.util.Random;
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class cipher implements ActionListener

Now the decryption code
import java.math.BigInteger;
import java.util.Random;
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class decipher implements ActionListener
[Code] ....
The screenshots for respective codes are as attachments ....
