Hi Shridhar,

* Have you run the cactus samples (as is with no modification except modifying build.properties) ? It should run fine

* I believe your problem is either with :

- a jar missing in the classpath (client or server)

- the cactus.properties file not containing correct url for the servlet redirector

- your web.xml not having a correct mapping for the servlet redirector (not in line with cactus.properties)

hope it helps

-Vincent

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

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.
