Whats wrong here? 'PACKAGE'

[Arul Jose]

I have put two classes in a package folder app.

The RegisterAction class is using the RegisterForm class. While compiling, the RegisterAction class is not able to identify the RegisterForm Class. why?

[aruljose@aruljose ex]$ javac WEB-INF/classes/app/RegisterAction.java
WEB-INF/classes/app/RegisterAction.java:12: cannot resolve symbol
symbol  : class RegisterForm
location: class app.RegisterAction
RegisterForm rf = (RegisterForm) form;
^
WEB-INF/classes/app/RegisterAction.java:12: cannot resolve symbol
symbol  : class RegisterForm
location: class app.RegisterAction
RegisterForm rf = (RegisterForm) form;
                   ^
WEB-INF/classes/app/RegisterAction.java:20: cannot resolve symbol
symbol  : variable UserDirectory
location: class app.RegisterAction
UserDirectory.getInstance().setUser(username,password1);
^
WEB-INF/classes/app/RegisterAction.java:22: cannot resolve symbol
symbol  : class UserDirectoryException
location: class app.RegisterAction
} catch (UserDirectoryException e) {
         ^

[aruljose@aruljose ex]$ ls WEB-INF/classes/app/
RegisterAction.java  RegisterForm.class  RegisterForm.java

RegisterForm.java

package app;
 
import org.apache.struts.action.*;
 
public class RegisterForm extends ActionForm {
 
protected String username;
protected String password1;
protected String password2;
 
public String getUsername () {return username;}
public String getPassword1() {return password1;}
public String getPassword2() {return password2;}
 
public void setUsername (String username) {this.username = username;}
public void setPassword1(String password) {this.password1 = password;}
public void setPassword2(String password) {this.password2 = password;}
 
}

RegisterAction.java

package app;
 
import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.io.*;
 
public class RegisterAction extends Action {
 
public ActionForward perform (ActionMapping mapping,ActionForm form,HttpServletRequest req,HttpServletResponse res)
{
// b Cast the form to the RegisterForm
RegisterForm rf = (RegisterForm) form;
String username = rf.getUsername();
String password1 = rf.getPassword1();
String password2 = rf.getPassword2();
// c Apply business logic
if (password1.equals(password2)) {
try {
// d Return ActionForward for success
UserDirectory.getInstance().setUser(username,password1);
return mapping.findForward("success");
} catch (UserDirectoryException e) {
return mapping.findForward("failure");
}
}
// E Return ActionForward for failure
return mapping.findForward("failure");
}
}

Is the 'classes' directory in your classpath? If not, the class will not be found. Alternatively, do a "cd WEB-INF/classes" and start the compilation from there; then the class will be in the default classpath.

[vidhyasagar reddy]

use javac *.java


if u want to compile individually means set classpath for that package
