Hi all, I build an application based on "http://trailblazer.demo.jboss.com/EJB3Trail/persistence/index.html", which contains an EJB-project (JAR) and a Web-project (WAR). If I deploy both on the JBoss server, it runs wonderful. Now I deploy the web-project, i.e. the WAR to Tomcat Server 6.0. As I run it, I got error/Exception as follow: | Exception | | org.apache.jasper.JasperException: An exception occurred processing JSP page /addfund.jsp at line 46 | | 43: <br /> | 44: | 45: <% | 46: Collection <Fund> funds = cal.getFunds(); | 47: | 48: %> | 49: | | | Stacktrace: | org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:524) | org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:435) | org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:320) | org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266) | javax.servlet.http.HttpServlet.service(HttpServlet.java:803) | | | root cause | | java.lang.NullPointerException | org.apache.jsp.addfund_jsp._jspService(addfund_jsp.java:103) | org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) | javax.servlet.http.HttpServlet.service(HttpServlet.java:803) | org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:393) | org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:320) | org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266) | javax.servlet.http.HttpServlet.service(HttpServlet.java:803) | | The Fund is an Entity Bean. I am not sure if I have to include more libraries (JARs) in the web-project or should I copy them in the /lib of Tomcat?
