Error appears before running the Webdriver test on a Hudson slave

Question

We are trying to migrate our system to WebDriver from Selenium 1. Thorough the Hudson slave an error message appeared, but the test run fine in eclipse.

Environments:

Hudson master: Linux machine
Hudson slave: windows 7, x86

Java version: 1.7.0_03

System: A new Hudson job was set up for the task, with the same configurations as it was for Selenium 1 test suites. The job executes a target from the build.xml file. clean,makedir and compile targets were ran successfully. On executing the tests the following error message appeared on Hudson Console:

run_shopping_travel_tests:
    [junit] Running com.example.tests.ExampleTests
    [junit] Tests run: 1, Failures: 0, Errors: 2, Time elapsed: 2.385 sec
    [junit] Test com.example.tests.ExampleTests FAILED
    [junit] Running com.example.tests.Example2Test
    [junit] Tests run: 1, Failures: 0, Errors: 2, Time elapsed: 0.752 sec
    [junit] Test com.example.tests.Example2Test FAILED
     [echo] selenium directory: C:\Selenium

The error:

    at com.example.tests.ExampleTests.setup(ExampleTests.java:43)

The java code for the test:

public class ExampleTests
{
    FirefoxDriver driver = null;

    @Before
    public void setup() {
         File profileDir = new File( "C:\\Selenium\\FirefoxProfile" );
         FirefoxProfile profile = new FirefoxProfile(profileDir);

         driver = new FirefoxDriver(profile); // line 43, where error appears
    }
    @Test
    public void T100_VerifyExampleTest() {
   // some test code here
    }
}

We have tried to run the test without "profile" and the same error message appeared.

Thanks in advance.

Problem solved. There were some jar libraries included which were used for compiling by -javac (in the ant script), but not by eclipse.

Solution: Check the jar files one-by-one,and delete the unnecessary ones from the lib folder.
