When I attempt to compile LookupAction.java, I receive the following error:

C:\Tomcat 4.1\webapps\ch03app\WEB-INF\classes>javac LookupAction.java
LookupAction.java:43: cannot resolve symbol
symbol : class LookupForm
location: class ch03.LookupAction
      LookupForm lookupForm = (LookupForm)form;
      ^
LookupAction.java:43: cannot resolve symbol
symbol : class LookupForm
location: class ch03.LookupAction
      LookupForm lookupForm = (LookupForm)form;
                               ^
2 errors

Here is my code (taken from the Wrox code download site):

package ch03;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

//import ch08.WileyActionMapping;

public class LookupAction extends Action {

  protected Double getQuote(String symbol) {

    if ( symbol.equalsIgnoreCase("SUNW") ) {

      return new Double(25.00);
    }
    return null;
  }

  public ActionForward execute(ActionMapping mapping,
    ActionForm form,
    HttpServletRequest request,
    HttpServletResponse response)
    throws IOException, ServletException {

    String theMapping = mapping.getClass().toString();

// WileyActionMapping wileyMapping = (WileyActionMapping)mapping;

    Double price = null;
    String symbol = null;

    // Default target to success
    String target = new String("success");

    if ( form != null ) {

      LookupForm lookupForm = (LookupForm)form;

      symbol = lookupForm.getSymbol();

      price = getQuote(symbol);
    }

    // if price is null, set the target to failure
    if ( price == null ) {

      target = new String("failure");
    }
    else {

// boolean logging = wileyMapping.getLogResults();
// if ( logging ) {
//
// System.err.println("SYMBOL:"
// + symbol + " PRICE:" + price);
// }

      request.setAttribute("PRICE", price);
    }
    // Forward to the appropriate View
    return (mapping.findForward(target));
  }
}

Any help is greatly appreciated.

The code that is available for download is just plain wrong and bears no resemblance to the examples in the book.

I see that you have already commented out the import for the chapter 8 stuff and the mapping junk too.

I think that you may have a classpath issue.

When I compiled, I had to move the source to the WEB-INF/classes directory and I used the following command line

javac -classpath .;%CLASSPATH% -d LookupAction.java

I had to add "." (the current working directory) to the classpath so that it could reference the other classes in there.

Using -d will make the compiler drop the .class file into the right subdirectory on compile.


On review, I suspect that you are compiling the files one at a time from the command line. If you compile the LookupForm.java first it might resolve your "not found" error

You need to compile ALL of your classes in the ch03 package at the same time to get around this problem. Use something like this:

javac -classpath %CLASSPATH%;C:\jakarta-struts-1.2.4\lib\struts.jar; *.java

The "*.java" should compile all classes and solve your problem.
