Help for Apache-Tomcat - JSP error
I am new for Tomcat. I installed jdk1.5.0_09 and Tomcat5.5.20 on Windows 2003 Server. I would like to connect Tomcat to database. I was able to see the log in page. However, I got an error below when I tried logon.
Any help would be greatly appreciated!

I am having the same problem as well. I have narrowed it down to the static include directive below:
<%@ include file="/includes/pages/pageheader.jspf"%>
This generates the following collection code in the enclosing JSP page:
private static java.util.List _jspx_dependants;
static {
_jspx_dependants = new java.util.ArrayList(1);
_jspx_dependants.add("/includes/pages/pageheader.jspf");
}
Now, if I remove the include, I lose my common page heading, but my page compiles. If I cut and paste the code directly into the JSP page, it works. Because the heading requires the request.getContextPath() to locate some image files, I can't use a <jsp:include ... /> command instead.
Anyone have any thoughts on how to make the included fragment work as an includes?

Okay, I have a work-around. I am using Java 1.5 with a Tomcat 5.5.20 server. What I need to do is get the JSP compiler to treat the code as Java 1.4, taking the whole question of generics off the table. I could do any of the following:
* Use Java 1.4 throughout the project
* Upgrade to Tomcat 5.5.23 or Tomcat 6.0, which may or may not fix the problem -- I am testing this in the future
* Instruct Tomcat to treat the source to the JSP page as Java 1.4
I tried the last method by adding the following code to the servlet JSP information in the server's web.xml file.
<init-param>
<param-name>compilerTargetVM</param-name>
<param-value>1.5</param-value>
</init-param>
<init-param>
<param-name>compilerSourceVM</param-name>
<param-value>1.4</param-value>
</init-param>
This gives a complete entry of:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>xpoweredBy</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>mappedfile</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>compilerTargetVM</param-name>
<param-value>1.5</param-value>
</init-param>
<init-param>
<param-name>compilerSourceVM</param-name>
<param-value>1.4</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
I hope this can help you.

With Tomcat version 5.5.23, this edit is not necessary. The web.xml will work "right out of the box."
