Re: Beginner - NoClassDefFoundError

Hi Chris
I've implemented your suggestion as well as the one from the Kazuhito. I still get the NCDFE error. However when I try to hit the SevletTestRunner for the first time I get the following error:

java.lang.VerifyError: (class: org/apache/cactus/client/connector/http/HttpClientConnectionHelper, method: addUserData signature: (Lorg/apache/cactus/WebRequest;)V) Incompatible object argument for function call at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:141) at org.apache.cactus.configuration.BaseConfiguration.<clinit>(BaseConfiguration.java:94) at org.apache.cactus.ServletTestCase.init(ServletTestCase.java:188) at org.apache.cactus.ServletTestCase.<init>(ServletTestCase.java:164)

I read in the mail archives, this error is because all the cactus jar files are not compiled with the same compiler and have different versions. Is it true? If it is how do I get rid of it? When I refresh the page the error changes to the NoClassDefFoundError.

btw. My project structure looks like this now:

TestCactus.jar
   com
       cactus
           TestCactusHome.class
           TestCactusBean.class
           TestCactus.class
   META-INF
       jboss.xml
       ejb-jar.xml

TestCactus.ear
   application.xml
   TestCactus.war
        WEB-INF
            jboss-web.xml
            web.xml
            lib
                log4j-1.2.8.jar
                junit-3.8.1.jar
                commons-logging-1.0.1.jar
                cactus-1.6dev-20031029.jar
                commons-httpclient-2.0-rc2
                aspectjrt-1.1.1.jar
                httpunit-1.5.3
            classes
                com
                    cactus
                        TestCactusHome.class
                        TestCactusBean.class
                        TestCactus.class
                        TestCactusTest.class

Thanks for your response and please let me know where I'm doing wrong.

Thanks
Srikrishna

Hi Srikrishna,

you need to remove the TestCactus.jar from the EAR, so that the test classes only appear in the web-app. Otherwise the test classes are loaded from a class-loader one level above the class-loader that loads cactus.jar, thus resulting in the NCDFE you're getting.

Hope that helps,
  Chris

Hi All,
I've tried my best to read through the mailing lists and implement all the suggestions, but still I'm getting the same error.

My Error is
(java.lang.NoClassDefFoundError
at org.apache.cactus.ServletTestCase.init(ServletTestCase.java:188)
at org.apache.cactus.ServletTestCase.<init>(ServletTestCase.java:164) ...

I'm using the eclipse integration from the nightly build area and the plugin is
C:\eclipse\plugins\org.apache.cactus.eclipse.runner_1.6dev-20031029. I'm using JBoss as my application server.

My EAR file has got the following Structure

TestCactus.ear
   application.xml
   TestCactus.jar
       com
           cactus
               TestCactusHome.class
               TestCactusBean.class
               TestCactus.class
       META-INF
           jboss.xml
           ejb-jar.xml
   TestCactus.war
        WEB-INF
            jboss-web.xml
            web.xml
            lib
                log4j-1.2.8.jar
                junit-3.8.1.jar
                commons-logging-1.0.1.jar
                cactus-1.6dev-20031029.jar
                aspectjrt-1.1.1.jar
            classes
                com
                    cactus
                        TestCactusHome.class
                        TestCactusBean.class
                        TestCactus.class
                        TestCactusTest.class

In the client side I've the following jar files

junit-3.8.1.jar
cactus-ant-1.6dev-20031029.jar
commons-httpclient-2.0-rc2.jar
aspectjrt-1.1.1.jar
commons-logging-1.0.3.jar
httpunit-1.5.3.jar
cactus-1.6dev-20031029.jar

I've the mappings for ServletRedirector and ServletTestRunner in my web.xml. When I try the ServletRedirector page it shows me the blank page and I assume there are no errors in the process. However when I use the ServletTestRunner and call the com.cactus.TestCactusTest class it throws me a class not found error.

Please let me know where I'm doing wrong.


Thanks
Srikrishna
