classpath - Mahout Java compilation issue -

-

I am reading Mehout In Action and I am working in chapter 2. 

  $ javac RecommenderIntro .java RecommenderIntro.java thread: Error: package org.apache.mahout.cf.taste.impl.model.file Import Organization does not exist. Org.apache.mahout.cf.taste.impl.model.file *; ^ RecommenderIntro.java:3: Error: package org.apache.mahout.cf.taste.impl.neighborhood does not exist import org.apache.mahout.cf.taste.impl.neighborhood. *; ^ RecommenderIntro.java:4: Error: package org.apache.mahout.cf.taste.impl.recommender Import Association org.apache.mahout.cf.taste.impl.recommender does not exist. *;   
 I have installed Mahout via yum:    $ sudo yum install mahout ... Downloading packages: mahout-0.7 + 12 -1.cdh4.2.0 P0.9.el6.noarch.rpm | 94 MB 05:17 Running rpm_check_debug Running Transaction Transaction Transaction Running Transaction Updating: MaHout -0.7 + 12-1 CDH 4.2.0.p0.9 L6.Narp 1/2 Cleanup: Mhout -0.7 + 8-1 cdh 4 .1.2.p0.12.el6.noarch 2/2 Verification: Mahavat-07 + 12-1 cd 4.2.0.p0.9. 66.noarch 1/2 Verification: Mahavat -0.7 + 8-1 CDH 4.1.2. P0.12.el6.noarch 2/2 Updated: mahout.noarch 0: 0.7 + 12-1.cdh4.2.0.p0.9.el6 complete!   
 I'm completely new to Java  
 Am I compiling it incorrectly?  
 Do I need to include some paths on the command line with applying Javak?  
  
 
 
 This is a simple Java question, installing a package is nothing but your  javac < / Code> affects the order you always need to include all sections required by compiling in your  -cp  argument.  
 It is easy to use a build system, such as an IDE, or Maven, where you can import dependency.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

I am using a Google line chart on my page, which refreshes every 5 seconds but weird thing It is that every refresh chart causes the line to be removed, although the size of the chart remains the same. My script - google.load ('visualization', '1', {package: ['corechart']}); Google.setOnLoadCallback (drawLine); // call clickChart when the google.load () function meets the drawLine () {var gaugeData = new google.visualization.DataTable (); GaugeData.addColumn ('string', 'time'); // X-axis gazeta.dk column ('number', 'memory'); // Y-axis gazedata.edc column ('number', 'cpu'); // Y-axis square gauge option = {title: 'system description'}; // tile of var gauge chart; Var tempArray; // store json object value from server var tempArray2; // Server gauge = Modify the json object value = new google.visualization.LineChart (document.getElementById ('line_chart_div')); SetInterval (function () {$ aja...

-
So, I ended up making a Sudoku Solver, but I want to improve it. To do this, I need to reach betterJTextField to documentListener . I am using a documentListener to read from my betterJTextFields in real-time, I have the problem that insertUpdate (DocumentEvent e) . I need to reach Better Zest Field that happened to DocumentEvent . For example, if invalid input, would be better zestfield turn red etc. I have all my better zestfield in the matrix if you should know. Each area handles a number in the Sudoku. @ Override public zero inserted (DocumentEvent e) {// Code removed which checks that the input in the fine zest field is OK. } ( JFormattedTextfield extended JTextField ) public class betterJeststeffiledJFormattedTextField {private int row; Private int column; Public BetterJustStस्टfield (format format, infinite row, EIT column) {super (format); This.row = Line; This.column = Column; // To-O Auto-Generated Constructor Stub} Public Ent Miller () {ret...
