Copy the HelloWorld.class serlvet to the DefaultWebApp/WEB-INF/classes directory.
In web.xml
<servlet>
<servlet-name>
HelloWorld
</servlet-name>
<servlet-class>
examples.servlets.HelloWorld
</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>
HelloWorld
</servlet-name>
<url-pattern>
HelloWorld
</url-pattern>
</servlet-mapping>

still error!!!!
i deloy the ejb as a jar file

[root@kingson applications]# jar tf helloWorldBean.jar
META-INF/MANIFEST.MF
META-INF/
META-INF/weblogic-ejb-jar.xml
META-INF/ejb-jar.xml
hello/
hello/HelloWorldHome.class
hello/HelloWorldBean.class
hello/HelloWorld.class
hello/HelloWorldBean_nru4ls_HomeImplRTD.xml
hello/HelloWorldBean_nru4ls_EOImplRTD.xml
hello/HelloWorldBean_nru4ls_EOImpl.class
hello/HelloWorldBean_nru4ls_Impl.class
hello/HelloWorldBean_nru4ls_HomeImpl.class
_WL_GENERATED

i also copy the helloClient.jar to the <web>/WEB-INF/classes
and the <web>/WEB-INF/lib
but it still not works
maybe i should know what should be included in the helloClient.jar
i just copy the

helloWorld.class
helloWorldBean.class
helloWorldHome.class
and the ejb-jar.xml.weblogic-ejb-jar.xml
into the helloClient.jar

also i set the EJB path into the bea system classpath
so anything error???
why the servlet not works
my Swing client can access the EJB
but the servlet not
i am exhausted
