java.io.StreamCorruptedException: InputStream does not contain a serialized object

[Shridhar MD]

Hi Cactus folks,   Need help.   When I run JUnit test runner I get the following error message:   ----- ooo -----   java.io.StreamCorruptedException: InputStream does not contain a serialized object  at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:849)  at java.io.ObjectInputStream.<init>(ObjectInputStream.java:168)  at org.apache.cactus.client.AbstractHttpClient.doTest(AbstractHttpClient.java:148)  at org.apache.cactus.AbstractTestCase.runGenericTest(AbstractTestCase.java:422)  at org.apache.cactus.ServletTestCase.runTest(ServletTestCase.java:130)  at org.apache.cactus.AbstractTestCase.runBare(AbstractTestCase.java:371)   ----- ooo -----   I assume that I have made all the configs correctly.   I have been having this problem for a while and need help ... ...   My servlet engine: Tomcat 4.0. My Webapp: cactusTrial.     My Servlet class: TestServlet: ( placed under: cactusTrial/WEB-INF/classes/)   ----- ooo -----   import javax.servlet.*; import javax.servlet.http.*; import java.io.*;   public class TestServlet extends HttpServlet{    public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{   getAuthor(request);  }    public String getAuthor(HttpServletRequest request){   return (String)request.getSession().getAttribute("author");  }   }   ----- ooo -----   My test class: CactusTest : ( AT SERVER: placed under cactusTrial/WEB-INF/classes) and under my client: c:/cactusClient/ )   ----- ooo -----   import org.apache.cactus.*; import junit.framework.*;   public class CactusTest extends ServletTestCase{    private TestServlet servlet;    public CactusTest(String theName){   super(theName);  }    protected void setUp(){   servlet = new TestServlet();  }    public static Test suite(){   TestSuite suite = new TestSuite();   suite.addTest(new CactusTest("testGetAuthor"));   return suite;  }    public void testGetAuthor(){   session.setAttribute("author", "cactus tests author");   String result = servlet.getAuthor(request);   assertEquals("cactus tests author", result);  } } // end class     I have ensured the following points:   1.    "cactus.properties " IS in the classpath of the client. All the required libs ( cactus.jar, junit.jar ... ... ) 2.    Server side libs are all put in the WEB-INF/lib/     I seem to have followed all the points given in the " ... howto".   When I run the Junit test runner I get the above " StreamCorruptedException ".   Can any one has an answer??   Cheers.   Shridhar Dhoopad
