Hi list,
I'm running Tomcat 4.0.5 on UNIX and I am experiencing compilation
errors when trying to compile a simple index.jsp file, which is only
twenty lines or so, as I'm trying to learn JSP and starting small. First
however, I'd like to get this question out of the way:
I've searched the web for information on Tomcat's directory structure.
According to one page I found, Tomcat should have a /bin directory,
which contains binary executables, such as startup.sh, which I can use
to restart Tomcat. When I navigate to my Tomcat installation, I can find
no /bin directory. The only directories I have are conf, work, logs, and
webapps. I assume this is a major problem. If so, should I re-install
Tomcat (and update to Tomcat 6.0 while I'm at it)?
I believe that problem leads to my JSP compilation errors problem. After
posting my Java errors on a Java forum for JSP, a user replied that once
I set the JAVA_HOME environment variable (it was set incorrectly and I
had to set it to the proper path), I need to restart Tomcat. However,
from what I've read online, I cannot restart Tomcat without executing
the commands from the /bin directory.
I'm going to post my JSP errors if that is alright, just in case the
problem is not based on the first one. If it is, please disregard this
part, as I will revisit it later.
I have a small index.jsp file, and I have a small scriptlet in it that
sets up an ArrayList<String>, for some basic tests. However, when I go
to compile the file, I get an error. The relevant parts of my file are
as follows:
<%@ page import="java.util.ArrayList" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title></title></head>
<body>
<%
ArrayList<String> al = new ArrayList<String>();
al.add("Row 1");
al.add("Row 2");
al.add("Row 3");
al.add("Row 4");
%>
<TABLE BORDER=2>
<%
for (int i = 0; i < al.size(); i++) {
%>
<TR>
<TD>Number</TD>
<TD><%=al.get(i)%></TD>
</TR>
<%
}
%>
</TABLE>
</body>
</html>
The relevant part of the error message is:
org.apache.jasper.JasperException: Unable to compile class for JSPNote:
sun.tools.javac.Main has been deprecated.
An error occurred between lines: 9 and 15 in the jsp file: /index.jsp
Generated servlet error:
/var/apache/tomcat/work/Standalone/localhost/_/index$jsp.java:68: '(' expected.
ArrayList<String> al = new ArrayList<String>();
Lines 9-15 are the lines in which the ArrayList<String> scriplet resides. I've checked my JDK version to make sure it supports generics, which it does. If this problem is not related to the first
problem, I believe there may be a problem with my CLASSPATH variable. What exactly do I have to set this variable to so Tomcat can
recognize the proper settings?
I hope this is not too much information. I will greatly appreciate any help
that can be provided.
Thanks,
Dan
