Powermock newbie/NoClassDefFoundError when mocking Apache DefaultHttpClient?

Problem appears to be solved by changing from java5 (IBM Websphere) to Sun/Oracle Java6.

I'm new to object mocking, and trying to create unit tests for some legacy code. I'm trying to use powermock for the first time, and encountering a NoClassDefFoundError on line 69 ( DefaultHttpClient mockClient = mock(DefaultHttpClient. Class);) (see trace below).

Can anyone give me a hand and point me in the right direction? @RunWith(PowerMockRunner. Class) @PrepareForTest(LoginClient.

Class) public class LoginClientTest { Properties props = null; @Before public void setUp() throws FileNotFoundException, IOException { props = new Properties(); props. Load(new FileInputStream(". /src/test/resources/LoginClient/default.

Properties")); } /** * Method description * @throws Exception * */ @Test public void loginPositiveTest() throws Exception { DefaultHttpClient mockClient = mock(DefaultHttpClient. Class); HttpResponse mockResponse = mock(HttpResponse. Class); StatusLine mockStatusLine = mock(StatusLine.

Class); Header headers = new BasicHeader2; headers0 = new BasicHeader("Set-Cookie", "COOKIE-DATA"); headers1 = new BasicHeader("Set-Cookie", "COOKIE-DATA-2"); whenNew(DefaultHttpClient. Class).withNoArguments(). ThenReturn(mockClient); when(mockClient.

Execute(isA(HttpUriRequest. Class))). ThenReturn(mockResponse); when(mockResponse.getStatusLine()).

ThenReturn(mockStatusLine); when(mockStatusLine.getStatusCode()). ThenReturn(HttpStatus. SC_OK); when(mockResponse.getAllHeaders()).

ThenReturn(headers); LoginClient client = new LoginClient(); UsernamePasswordCredentials creds = new UsernamePasswordCredentials(props. GetProperty("user"), props. GetProperty("password")); String result = client.

GetCookie(creds.getUserName(), creds.getPassword()); System.out. Println(result); assertNotNull(result); } } java.lang. NoClassDefFoundError: org.apache.http.impl.client.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
