I will use OJB in a web application running on Tomcat 4.1.24 using JDK 1.4.1 on a Win2K box.
After installing OJB 1.0.rc3, the check bin\build junit runs properly. The tutorial1 works fine also.
Now, i create the ojb-servlet webapp and deploy it to tomcat webapps. Tomcat greater 4.1.10 need a deployment descriptor file for invoking servlets:
my web.xml -------------------------- <?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>
<display-name>Apache OJB V1.0 28.6.2003</display-name>
<description> WebApp for Apache OJB V1.0 28.6.2003 KreutzerSoft.de</description>
<servlet> <servlet-name> TestServlet </servlet-name> <servlet-class> org.apache.ojb.servlet.TestServlet </servlet-class> </servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/servlet/TestServlet</url-pattern>
</servlet-mapping> <!-- Nachfolgendes mapping aktivieren für 4.1.10 Kompatibilität
!in produktiven System deaktivieren!
-->
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
</web-app>
---------------------------------Calling the Servlet via http://localhost:8080/ojb-servlet/servletTestServlet throws the following Exception:
*root cause*
java.lang.NoClassDefFoundError
at
org.apache.ojb.broker.PersistenceBrokerFactory.defaultPersistenceBroker(Unknown Source)
at org.apache.ojb.servlet.TestServlet.getBroker(Unknown Source)
at org.apache.ojb.servlet.TestServlet.getTableIterator(Unknown Source)
at org.apache.ojb.servlet.TestServlet.doGet(Unknown Source)
.....The db-ojb-1.0.rc3.jar containing the class org.apache.ojb.broker.PersistenceBrokerFactory is installed in the right place in WEB-INF/lib.
Where I'm going wrong. Can anywon help me.
Thanks, gerhard
