<jsp:useBean id="b" class="mybeans.FirstBean" />
and tomcat 4.1 is failed to find this bean and giving me following error
cannot resolve symbol
symbol : class StudentBean
location: package mybeans
mybeans.FirstBean b = null;
all my class and directory structure is ok i am puzzle why this error is coming, plz help me quickly i need solution quickly ...

Error is for StudentBean, not for FirstBean. So check for it.

Error when activating - "cannot resolve symbol"

Hi everybody!
I created a WebDynpro DC referencing some other DC's, one of them containing some generated Enterprise Connector classes.
A local build works fine, the WebDynpro looks and works as expected when deployed to our J2EE server. When I activate the associated activities, all DC except the WebDynpro DC compile o.k., but the WebDynpro compilation throws some "cannot resolve symbol" errors, the symbols being the generated classes from the Enterprise Connector DC.
The Activation Log of this component shows that only one class of this DC is being compiled and packed into the public parts of the DC:

Any hint on what produces such an error or what information you'd need so say something ?
Thanks!

After messing around a bit, we finally deleted both assembly and compilation public parts of all the referenced DC's, created new ones and reestablished the references exactly as defined previously, and now it works properly. Strange thing, though...

Error when compiling cannot resolve symbol

I am kind of new to java please take a look into this code. I am getting this error cannot resolve the symbol.
this is the first class I saved under folder called javapractice as t1. I don't get any error message when I compile this, but when I compile the second class I got the error message.It would be appreciated if someone can help. thanks
package javapractice;
public class t1{
double a;
double b;
double c;
t1(double ax){
a = ax;
b = 0;
c = 0;
this is the second class also I saved as t2 under javapractice folder. when I compile this class I got the error cannot resolve the name.
package javapractice;
public class t2 {
public static void main(String args[]) {
t1 d = new t1();
d.a = 3;
System.out.println(d.a);
System.out.println(d.b);
System.out.println(d.c);

The problem ist1 d = new t1();You need to pass a double param. to the constructor of t1t1 d = new t1((double)10.0);

Getting error message Cannot Resolve Symbol when trying to compile a class

Is ConnectionPool in this "cal" package as well as PooledConnection? From the directory you are compiling from it appears that it is. If it is, then you are compiling it incorrectly. To compile ConnectionPool (and PooledConnection similarly), you must change the current directory to the one that contains cal and type
javac cal/ConnectionPool.

IntValue - ")" expected and Cannot Resolve Symbol

I used intValue to convert an Integer to primitive (see below) and ran into syntax errors.
                LogDataBean lb = new LogDataBean();
                lb.setLog_time( ( String )row.get( "LOG_TIME" ) );
                lb.setLog_pid( intValue( Integer )row.get( "LOG_PID" )); //where syntax error occur
                lb.setLog_user( ( String )row.get( "LOG_USER" ) );the row.get( "LOG_PID" ) gets the value of the column "LOG_PID" from a database table and returns an object. Therefore, I first cast the object to Integer and then try to use the intValue to convert it to a primitive int.
But, the statement resulted in compilation error: ")" expected.
When I modified the statement a little bit by adding a pair of parenthesis:
                lb.setLog_pid( intValue( ( Integer )row.get( "LOG_PID" ) ) ); //where syntax error occurI got "Cannot Resolve Symbol: intValue". I have import java.lang.Integer in the beginning of the class.

Integer.parseInt(row.get( "LOG_PID" ))
I'm assuming thats what you want to. Although you syntax is terribly wrong. Have a look at some tutorials.

JSP page "cannot resolve symbol"

Hi,
I'm using j2sdk1.4.2_01 and tomcat-5.0.13. I'm developing within Eclipse 3.0.0 with the Tomcat plugin.
In my project ("Agenda2") i only created one class ("Persona"), that is correctely compiled (%TOMCAT_HOME%\webapps\Agenda2\WEB-INF\src\Persona.java results in %TOMCAT_HOME%\webapps\Agenda2\WEB-INF\classes\Persona.class, and 0 problems are shown in the Problems list.
In %TOMCAT_HOME%\webapps\Agenda2 i have my Edit.jsp, that begins with these lines:
<%@ page language="java" contentType="text/html" %>
<HTML>
<HEAD>
<TITLE>Edit</TITLE>
</HEAD>
<BODY>
<jsp:useBean id="personaAtt" class="Persona">
    <jsp:setProperty name="personaAtt" property="*" />
</jsp:useBean>
....When i call the JSP from the browser, i get this error:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 8 in the jsp file: /Edit.jsp

      ^The error message mentions line 8, which is the one following <BODY>, that is

----jspDoes anybody can see the problem ?

Thanks! I'm going to try to put the class into a package as both you have suggested, and i'll post here the result.
In the meantime i have a related newbie question:
putting the class into a package, is this kind of a workaround, or it's the "normal thing" ?
I mean, is it mandatory to put classes into a package in order to import them from JSP pages ?
It was my understanding that it isn't mandatory, but - from your replies and many other posts in this forum - i'm starting to think that i'm wrong.

Compiler error cannot resolve symbol

Hi people,
i'm having this compile time error that, when i create a class and calling that class in another class gives the error cannot resolve symbol classname and it also happened when i created a bean and referencing the bean class in another bean when i'm using Jsp. thanks in advance.

It would be helpful if you post the exact error message. If you use a system Classpath, then it must contain the root directory for the package directory(s).
For example, if the source code for a file starts with
package my.package;
and you have a directory structure c:\myjava\classes\my\package then the Classpath must contain c:\myjava\classes.

There is no way to be able to see MyDocumentListener class in the way you wrote. The reason is because MyDocumentListener class inside the constructor itself. MyDocumentListener class is an inner class, not suppose to be inside a constructor or a method. What you need to do is simple thing, just move it from inside the constructor and place it between two methods.
that's all folks

Cannot resolve symbol error even with class imported

Hi
I'm trying to print out a java.version system property but keep getting a
cannot resolve symbol error

I've looked at the API and getProperty() is a method of lang.System
Can anyone throw any light?

Thanks Jos
It compiles but I now get a runtime error
Exception in thread "main"

What do you reckon is the problem?
thanks
java -cp .;<any other directories or jars>
YourClassNameYou get a NoClassDefFoundError message because the
JVM (Java Virtual Machine) can't find your class. The
way to remedy this is to ensure that your class is
included in the classpath. The example assumes that
you are in the same directory as the class you're
trying to run.I know it's a bad habit but I've put this file (PropertiesTest.java) and the compiled class (PropertiesTest.class) both in my bin folder which contains the javac compiler

     Class.forName(sun.jdbc.odbc.JdbcOdbcDriver);
m_con = DriverManager.getConnection("jdbc:odbc:sitewd", "", "");
How can i fix it? thanks

Replace the Statement
Class.forName(sun.jdbc.odbc.JdbcOdbcDriver);
as
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

Cannot resolve symbol class Scanner (Error)

For whatever reason I get the error message "cannot resolve symbol class Scanner" when trying to run this:
import java.io.*;
import java.util.*;
public class NameReversal
     public static void main(String args[])
          System.out.print("Enter your name: ");
          Scanner Reader = new Scanner(System.in);
          String first = Reader.next();
          String finl = Reader.next();
          int z = first.length();
          int v = finl.length();
          int y = z-1;
          int f = y-1;
          for(int i = y; i>=0; z--)
          System.out.print(first.charAt(1));
          System.out.print(" ");
          for(int p = f; p >= 0; p--)
          System.out.println(finl.charAt(p));
}

The Scanner class is in the JDK version 1.5 or later. You must be using an earlier version.

Error:cannot resolve Symbol class"name"

when I have compiled Bean class named SlBean which has primary class named pk, I recevied following error message(I compiled pk class without error) :
cannot resolve symbol
symbol : class pk
location: class SlBean
public pk ejbCreate(

Sorry , its not classpath problem. You have to simply import the pk class if its in any package. I am assuming you have packaged your pk class with ejb jar file.
for eg. if your class is
package abc.xyz
public class pk
then in your bean class import
import abc.xyz.pk;

I use j2sdk1.4.2_04
when I try to compile my program using Formatter, it response error "cannot resolve symbol"
Pls help!

Where did you get this java.util.Formatter from? If you check the official 1.4.2 API for Java, that class does not exisit! However, java.util.logging.Formatter, does exisit...

If you ment: java.util.logging.Formatter have you checked the API to make sure you are using it correctly???
