java.lang.NoClassDefFoundError-Selenium RC with Junit and EClipse IDE

1.I downloaded Jdk-7 and set the path in C:\Program Files\Java\jdk1.7.0\bin(Environment variable in Control panel)

2.I downloaded selenium server in C:\downloads(I am able to run the server using the following commands,
java –jar selenium-server-standalone-2.4.0.jar)
3.I downloaded Eclipse IDE and Created new project(myproject) and I created a package under this project com.example.tests.
while I create new project I added junit3.jar using Add library and I added Java client driver using Add External Jars
4.I recorded the script(I am opening google page and searching seleium) using selenium IDE and Exported Test case as-Junit3(RemoteControl) and I saved it.
(I am able to open this script and I copied the changed code from-C:\selenium\selrcexjav )
5.I created a new class(selrcexjav) under myprojec\com.example.tests
6.I past all the code here and i did modifications.This is my modified script

package com.example.tests;
import com.thoughtworks.selenium.*;
import java.util.regex.Pattern;
import junit.framework.*; //added
public class selrcjav extends SeleneseTestCase {
public void setUp() throws Exception {
setUp("http://www.google.com/", "*chrome");
}
public void testSelrcjav() throws Exception {
selenium.open("about:home");
selenium.type("id=searchText", "selenium");
selenium.click("id=searchSubmit");
selenium.waitForPageToLoad("30000");
selenium.click("link=Selenium - Web Browser Automation");
selenium.waitForPageToLoad("30000");
assertTrue(selenium.isTextPresent("Selenium"));
}

public static Test suite() {

//method added

return new TestSuite(selrcjav.class);

}

public void tearDown(){

//Added . Will be called when the test will complete

selenium.stop();

}

public static void main(String args[]) {

// Added. Execution will started from here.

junit.textui.TestRunner.run(suite());






7.I started the selnium server and I try to compile this as a java application in eclipse.
I am getting following error in eclipse

Hi Uma,

I was confronted the same problem. After an hour work and a bit luck I finally could get one step forward:

I was a little bit confused, because the package com.google.common.base actually is part of the selenium server. So I gave it a try and added the server-jar file to the run configuration of the jUnit test - and it worked!

Hope I also managed to upload the screenshot correctly:

Thanks for the solution.

I am not using Eclipse and running Junit test from command line and getting the exact error.

Does some one know how to add server-jar file to the run configuration of the jUnit test, when not using Eclipse.

Hi neeshal,

you have to put the jar-files to your classpath.
I find the explanation at the following site very usefull:
http://junit.sourceforge.net/doc/faq/faq.htm

Go to section 6.1 ("What CLASSPATH settings are needed to run JUnit?") and 6.2 ("Why do I get a NoClassDefFoundError when trying to test JUnit or run the samples?").

Greets,
Holger
