Cannot resolve symbol dropdown1 from the tutorial

Has anyone a clue to why javac won't compile the button action. I looks like it can't find the dropdown1 droplist despite the fact that it is visible in the gui editor.
here is my offending code:
String name=(String)dropdown1.getValue();
And the error code:
untitled\Page1.java [76] cannot resolve symbol
symbol : variable dropdown1
location: class untitled.Page1
String name=(String)dropdown1.getValue();

Sounds like a bug.
I'm sure the engineering team would love to have some more info on this. Can you file a bug here:
http://developers.sun.com/prodtech/javatools/jscreator/bugreport.jsp
From my experience, they are taken very seriously and if it's already filed and has workaround, it'll be sent to you.
For sending the source code, I'm simply meant pasting it into the message box (using eventually formatting (see "code" button).
thanks,

Cannot Resolve Symbol netscape.javascript.JSObject

I am trying to communicate fom an applet to a javascript. I am usinjg jdk1.3.1 and did an import netscape.javascript.JSObject; in my applet class.
When I compile I get cannot resolve symbol JSObject. The import does not seem to work.
Do I have to download the package from somewhere and put it in the jdk1.3.1 dir in some place?
Thanks

Ive netscape 7.1 and the JSDK 1.4.2. The Java40.Jar doesnt seem to be present in my netscape folder anywhere so I assume that it isnt included in the newest version of netscape.
I tried using the javaws.jar that came with my JSDK but it didnt work. I opened it up and searched it and saw no mention of a JSObject file.
Im a little confused at this point. Where can I look up the location of the JSObject?

Import javax.ejb.EJBHome; cannot resolve symbol

Hi i wonder if anyone can help me. I have read alot of the posts regarding this issue and have tried everything to do with the paths and environmental variables and even reinstalled everything.
import javax.ejb.EJBHome; cannot resolve symbol
This is the problem i keep getting and here are the paths that i set:
SET PATH=c:\j2sdkee1.3\bin;c:\jdk1.3.1_01\bin;c:\jakarta-ant-1.3\bin
SET ANT_HOME=c:\jakarta-ant-1.3
SET JAVA_HOME=c:\jdk1.3.1_01
SET J2EE_HOME=c:\j2sdkee1.3
SET CLASSPATH=c:\j2sdkee1.3\lib\j2ee.jar;c:\jakarta-ant-1.3\lib\ant.jar;c:\jdk1.3.1_01\lib\tools.jar
What am i doing wrong???

Im not sure, everything looks ok to me, but here is what i tried:
I wrote this little test class, and compiled it
import javax.ejb.EJBHome;
public class test
public test()
I got the same error you did (or similar)
D:\>javac test.java
test.java:1: package javax.ejb does not exist
import javax.ejb.EJBHome;
^
1 error
then I added the j2ee.jar to my classpath and everything worked fine.
here are my env vars:
JAVA_HOME=d:\dev\jdk
J2EE_HOME=d:\dev\j2sdkee
CLASSPATH=...;%J2EE_HOME%\lib\j2ee.jar
If I were you I would double check all the paths you have set up then try a simple case like the one above. If your running NT/2000 make sure the JAVA_HOME, J2EE_HOME and CLASSPATH are system variables not user variables. Another thing you can try is adding the j2ee.jar to the classpath with the -classpath compiler switch.
javac -classpath %CLASSPATH%;d:\dev\j2sdkee\lib\j2ee.jar test.java
Other than those things I'm not sure
Good Luck

Cannot resolve symbol when the classes are in the same package

i have one interface and two classes all in the same package. am getting " cannot resolve symbol", when the code refers to the interface or the class .
the package name is collections.impl and
the directory i used to store all the java files:
c:\jdk\bin\collections\impl.
isthere any othe option other than compiling all the files from the comand line at the same time?
please help - i m new to java.

If you have:
I.java:
package some;
public interface I {
    void method();
}A.java:
package some;
public class A implements I {
    public void method() {
        new B();
}B.java:
package some;
public class B implements I {
    public void method() {
        new A();
}in c:/temp/some for example
you can compile your files with
javac c:/temp/some/*.java
It seems that you have errors in your code.
Recheck it twice or use NetBeans IDE(http://www.netbeans.org) it will do this for you ;)

I've been struggling with the same issue. The difference is that my system says I'm using version 1.6.0_05. I've tried running jucheck.exe. It tells me I've got the latest version installed.
Here is the code:
import java.lang.StringBuilder;
import java.util.Formatter;
   public class UsingFormatter {
     public static void main(String[] args) {
       if (args.length != 1) {
         System.err.println("usage: " +
           "java format/UsingFormatter <format string>");
         System.exit(0);
       String format = args[0];
       StringBuilder stringBuilder = new StringBuilder();
       Formatter formatter = new Formatter(stringBuilder);
       formatter.format("Pi is approximately " + format +
         ", and e is about " + format, Math.PI, Math.E);
       System.out.println(stringBuilder);
   }When I type javac UsingFormatter.java, I get:
UsingFormatter.java:1: cannot resolve symbol

6 errors
The compiler refuses to recognize the symbols StringBuilder and Formatter.
I have spent hours googling for an answer and trying every suggestion. Nothing works, not even the one about dropping the computer from the rooftop.
Ultimately, what I'm trying to accomplish (in a different program) is to use a text file as a form letter template and replace the %s placeholders with stings from my form object.
Any advice?

Visual Studio 2012 cannot resolve symbol or Errors control is not a member of class

Visual Studio 2012 Web Site Project (Note not a Web application, so there are not Designer.vb files) > Site works perfectly fine and using IIS and attaching to IIS to debug code.
However, if I try to build the site inside of Visual Studio I am getting lots of Errors ‘pnlName’ is not a member of ‘Page_Name’ In the code behind I am getting errors ‘Cannot resolve symbol ‘pnlName’
.ascx Page
<li style="margin-right:0;" id="pnlName" runat="server"><a href="/cart" title="Checkout" class="global-checkout">Checkout</a></li>
.ascx.vb page
Me.pnlName.Attributes.Remove("style")
I have cleaned, rebuild and nothing gets rid of these errors, but again the site works as designed, but I would like to launch and debug inside of Visual Studio.

Cor,
What I am stating is this is a solution using the Web Site Project instead of a
Web Application Project.
Web Site projects do not require Designer.vb files, Web Application Projects add Designer.vb files in the solution.
Background: I have been hired to support a very successful e-commerce site that was built by a 3rd party vendor (I had no input on the contract or specification, because I would have went with
MVC). The site works 100% correctly, however from my 2003 - 2015 experience with Visual Studio and Web Development being in Web Forms and MVC I have always built ASP.NET Solutions using the Web Application Project Templates, which compiles the code down
to .dlls.
A Web Site project does not compile the code, but simply uses the .vb files and they have to be migrated to the server with the .aspx files. http://msdn.microsoft.com/en-us/library/dd547590%28v=vs.110%29.aspx
Currently the only way I can debug this Solution is to attach to the w3wp.exe process running locally on my work station.
The Solution is comprised of two Web Sites, which I cannot get it to compile because of the following errors -
'webServerControlName' is not a member of '(Protected Code Behind Class Name)' I am reaching out to the MSDN community to see if anyone has experienced this issue with
Web Site Projects.
I hope that clears up the Project Type question.

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

Hello All -
I am getting an error message cannot resolve symbol while trying to compile a java class that calls another java class in the same package. The called class compiles fine, but the calling class generates
the following error message:

I am using Sun JDK Version 1.3.0_02" and Apache/Tomcat 4.0. Both the calling and the called class are in the same directory.
Any help would be greatly appreciated.
tnx..

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.

Missing method body and cannot resolve symbol

I keep getting these two errors when trying to compile. I know that I need to call my fibonacci and factorial functions from the main function. Is this why I am getting the missing method body error? How do I correct this?
Am I getting the cannot resolve symbol because I have to set the num and fact to equal something?
Thanks
public class Firstassignment
public static void main(String[]args)
     System.out.println();
public static void fibonacci(String[]args);
     int even=1;
     int odd=1;
     while (odd<=100);
     System.out.println(even);
     int temp = even;
     even = odd;
     odd = odd + temp;
public static void factorial (String[]args);
     for (int count=1;
     count<=num;
     count++);
     fact = fact * count;
     outputbox.printLine("Factorial of" + num + "is" + fact);

Hey... :o)
the problem is that you've put semicolons at the end of the function signature, like this:
public static void fibonacci(String[]args);
}that should happen only when the function is abstract... so ur function should actually look like this:
public static void fibonacci(String[]args)
}also, i think you've missed out on the declarations (like what are fact and num??)....

Class error - cannot resolve symbol "MyDocumentListener"

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.

Cannot resolve symbol: class EJBObject

Using javac I get this compile error on this file Calculator.java

also run cloudscape, like "cloudscape -start" (no problems)

Import java.util.Formatter - cannot resolve symbol

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???

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
Generated servlet error:
    [javac] Compiling 1 source file
C:\Programmi\Java\tomcat-5.0.13\webapps\Agenda2\work\org\apache\jsp\Edit_jsp.java:48: cannot resolve symbol
symbol : class Persona
location: class org.apache.jsp.Edit_jsp
      Persona personaAtt = null;
      ^The error message mentions line 8, which is the one following <BODY>, that is
<jsp:useBean id="personaAtt" class="Persona">My impression is that there is some path problem, but despite my tries i can't get it.
The folders tree under %TOMCAT_HOME%\webapps\Agenda2\ is:
-WEB-INF
--classes
--lib
--src
-work
--org
---apache
----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.

Oracle jdbc drivers - cannot resolve symbol

while i'm not new to java, i am new to jdbc. need to connect a java app to an oracle database (hosted by a 3rd party). i have all the connection info. i've crafted a test program, but cannot get it to compile.
here's the code:
import java.sql.*;
public class SimpleJDBC
     public static void main(String[] args) throws SQLException, ClassNotFoundException
     Class.forName(oracle.jdbc.driver.OracleDriver);
     System.out.println("Driver loaded");
     Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@database.host:1521:class"); //, "username", "password");
     System.out.println("Database connected");
     Statement statement = conn.createStatement();
     ResultSet results = statement.executeQuery("select first_name, last_name from user_tbl where last_name = 'Kendall'");
     while(results.next())
          System.out.println(results.getString(1) + "\t" + results.getString(2));
     conn.close();
}i've set the classpath to the location of the ojdbc14.jar, and it shows in the classpath when i do a "set" on the cmd line. i've tried it in netbeans, eclipse, and straight cmd line.
i always come up with the same message (cannot resolve symbol) on the line where i call Class.forName(oracle.jdbc.driver.OracleDriver);.
i've tried compiling and setting the classpath at the same time. i added the ojdbc14.jar to the compile/build paths in both the ides. i even tried using the old classes12.jar. nothing has worked.
i can't figure out what else there is. within the ides, the intellisense will actually let me put that line in (piece by piece), but then it shows an error.
any suggestions?

Place the string name of the driver in quotes.

Cannot resolve symbol: HashMap, put and strings

Hi,
why woudl I get a "cannot resolve symbol" at the line indicated by <============
sec_cands[i] should be a String already.
Can someone help me ?
Thanks in advance.
HashMap temp = new HashMap();
String [] sec_cands = sec_ex.getTargetPhrases();
int sec_length = sec_cands.length;
String [] allCands = new String[total_length];
if (sec_length > 0 ) {
for (int i = 0; i < sec_cands.length; i++)
allCands[fr_length+i] = sec_cands;
temp.put(sec_cands[i], true); <=================

Sorry, I accidentally deleted a subscript from a line. The real code is "
HashMap temp = new HashMap();
String [] sec_cands = sec_ex.getTargetPhrases();
int sec_length = sec_cands.length;
String [] allCands = new String[total_length];
if (sec_length > 0 ) {
for (int i = 0; i < sec_cands.length; i++)
allCands[fr_length+i] = sec_cands;
temp.put(sec_cands[i], true); <=================

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.
