Organizing large JSP into smaller chunks

[Robin Clark]

I am trying to organize a very large JSP into smaller more organized chunks. However, when I implement some of the functionality in a separate java class, my jsp will not compile successfully because it can not see the new class. I have successfully compiled the java class and installed the .class file in my web application's WEB-INF/classes directory. I even created a jar file with the new class and placed it in the web application's WEB-INF/lib directory and the Tomcat common/lib directory. I've stopped and started Tomcat as well.
Here is an excerpt from the jsp:

  
<?xml version = "1.0"?>
<vxml version = "2.0">
<form>
<var name = "nextPrompt" expr = "'1'" />
<var name = "sessionCount" expr = "'1'" />
<block>
at the beginning of the file capture prompt 
</block>

<%@page import="java.util.*"%>
<%@page import="com.oreilly.servlet.MultipartRequest"%>
<%@page import="com.oreilly.servlet.multipart.*"%>
<% 
com.oreilly.servlet.multipart.MultipartParser mpP= new MultipartParser(request, 1000000);
Part pt;
String channelType = "";
String phoneNbr = "";
String promptID = "";
String promptNbr = "";
String audioStream = "";
// retrieve parameters from getFileName.jsp submit
while ((pt=mpP.readNextPart())!=null) {
    String name = pt.getName();
    ParamPart paramPart = (ParamPart)pt;
    if (name != null && name.equals("channel_type")) {
    channelType = paramPart.getStringValue();
} else if (name != null && name.equals("phoneNbr")) {
phoneNbr = paramPart.getStringValue();
} else if (name != null && name.equals("audio")) {
audioStream = paramPart.getStringValue();
} else if (name != null && name.equals("promptID")) {
    promptID = paramPart.getStringValue();
} else if (name != null && name.equals("promptNbr")) {
promptNbr = paramPart.getStringValue();
} else {
getServletContext().log("Got a parameter I did not expect");
}

}
}  // end of while loop to retrieve parameters passed in submit
UtteranceInfo utt = new UtteranceInfo(channelType, 
                                      promptID, 
                                      PromptNbr,
                                      phoneNbr);

The error that I get is when compiling the last statement that instantiates the UtteranceInfo object. The error message is:

  
Generated servlet error:
C:\Program Files\Apache Tomcat 4.0\work\Standalone\localhost\logTest\capturePrompt$jsp.java:123: Class org.apache.jsp.UtteranceInfo not found.
                UtteranceInfo utt = new UtteranceInfo(channelType, 
                ^

Here is an excerpt for the code for the UtteranceInfo class:

  
import java.io.*;
import java.text.*;
import java.util.*;
public class UtteranceInfo {

public static final String USERFILE = "users.txt";
public static final String TMPFILE = "tmpusers.txt";
    private String channelType;
private String promptID;
private String promptNbr;
private String phoneNbr;
private String servletPathRoot;
private String uttPathName;
private String date;
private int sessionNbr;

public UtteranceInfo(String channelType,
                     String sex,
                     String promptID,
                     String promptNbr,
                     String phoneNbr) {
    this.channelType = channelType;
    this.sex = sex;
    this.promptID = promptID;
    this.phoneNbr = phoneNbr;
    this.promptNbr = promptNbr;
    
//get the timestamp
Date today;
String dateString;
SimpleDateFormat formatter;
formatter = new SimpleDateFormat("ddMMyy_HHmm", Locale.US);
today = new Date();
date = formatter.format(today);     
}

private String getDate() {
return date;
}

I accidently submitted that post before I finished editting it. Here is the correct code excerpt from the UtteranceInfo class:

  
import java.io.*;
import java.text.*;
import java.util.*;
public class UtteranceInfo {

        private String channelType;
private String promptID;
private String promptNbr;
private String phoneNbr;

public UtteranceInfo(String channelType,
                     String promptID,
                     String promptNbr,
                     String phoneNbr) {
    this.channelType = channelType;
    this.promptID = promptID;
    this.phoneNbr = phoneNbr;
    this.promptNbr = promptNbr;
}

This is the first time that I have ever tried to instantiate a java class from within my jsp. I am using Tomcat 4.0.6 on Windows 2000 server.
Thank you very much for your help.

You need to put the class in a package other than the nameless "default" package.

[Frank Carver]

And you probably also need to add another line
<%@page import="whatever.UtteranceInfo"%>
so that your JSP knows where to look for the class.

Thank you. I am having trouble putting these pieces together. I have created a new directory WEB-INF/classes/utterance. In this directory is my .class file for my java class. I changed the java class to add a package statement to the top. Is this the correct syntax for the package statement?

  
package utterance;

In my jsp, I added an import directive like this:

  
<%@page import="utterance"%>

I bounced Tomcat, but I still get the following error when I try to execute
my jsp in a browser:

  
org.apache.jasper.JasperException: Unable to compile class for JSP
C:\Program Files\Apache Tomcat 4.0\work\Standalone\localhost\newtest\capturePrompt$jsp.java:8: Class utterance not found in import.
import utterance;
       ^
1 error

I am confused a bit further because I am trying to do this in Eclipse and I don't understand what it is doing when I try to create a new package, "utterance" under the WEB-INF/classes directory when my project is at the web application root level. What it does is create a directory under the web application root level for the .java file, then it places the .class file in the WEB-INF/classes/utterance directory. But I guess that question should be directed to the IDE forum.
Any help would be greatly appreciated.

I think that I figured this out. My import directive in the jsp was wrong. It should have been:

  
<%@page import="utterance.*"%>

I think that I am trying to learn too many new things at one time:
Java
JSP
VoiceXML
Eclipse
Tomcat
