Cannot find javac

I am running Red Hat 7.3 and I just installed java 2 sdk from Sun's website, I updated the path for the java directory I installed it to, but I cant compile any files. I did a search for the "javac" file and it isnt anywhere on my system. The "java" file is there but not javac. can any one please help this has been driving me crazy for days!

You may have installed the JRE rather than the JDK, which won't have the javac tool. Check to be sure you downloaded the correct file.

Cannot find javac.exe in j2se 1.5.0 jdk

hi
i have been installing and reinstalling JDK 5.0, yes it is jdk not jre...
and i cannot find javac.exe
does anyone has any solution?
thanks in advance.

Oh, and btw, you should uninstall everything (J2EE, J2RE/jre, Forte/S1S, and Webstart) - Then install J2SE, followed by J2EE, then S1S.
Don't install J2RE as a separate install - the J2SE install will also install it and Webstart.

My system cannot find javac!!

This is enough to drive me crazy. I use TextPad to develop Java apps, etc. One nice thing about it is, like other IDE's, you can compile and launch apps from within TextPad itself. One day, it just stopped being able to find the compiler. It finds the interpreter ok (AND THEY ARE IN THE SAME SPOT!). Well, I thought it was TextPad or something, but I just downloaded a web server to run my jsp pages and even though I have the bin folder of the jdk I want to use on my PATH, it (the jsp engine) cannot find the compiler! What the heck is going on? If I open a dos shell and type "java", it runs the interpreter (it finds it). If I type "javac" - I get "Exception in thread 'main' java.lang.NoClassDefFoundError: sun/tools/javac/Main"
Why can't my system recognize my compiler? I have tried adjusting my path to an different jdk (bin folder) and the same thing happens! Arggh - help, please!

It seems that u have installed JRE or other s/w like netscape, opera which gives JRE with them.
Now when u installed it, it overrides (better to say append) the ur system's path / classpath variable, now as u know what is JRE, it has only interpreter java, but not compiler javac.
So better to put ur jdk/bin path/classpath at last, in ur variable or autoexec.bat, whatever u used.
let's see what happen?

Cannot find javac program

Hello, I just recently installed Java 2 SDK, version 1.3.1 on my NT computer. After installation (went
by the book according to the java installation notes) and adding my path, I did a quick check in the
folder I installed to..in this cas C:\jdk1.3 . I do not see the javac.exe file listed in the bin at all (there is a javaw and java but no javac). I reinstalled it just to see if I was incorrect and I still don't see it at all so of course I can't really run anything as of yet. I downloaded from this website. Can anyone help me?

you should right-click the folder that contains jdk1.3 and click on "search" and then type the file name to search for wherever it is. Hope that helps any!

Javac = "cannot find symbol" when compiling class referencing other classes

I have several Java files in a directory which is declared as a package at the start of the files
package filemanager;
This program works perfectly in an IDE, however I'm having problems with compiling in command line.
I have set the classpath as I understand to be right for my computer to:
C:\Program Files\Java\jdk1.6.0_02\bin
I can compile a class that references no other classes in this package/directory.
However files which reference other classes bring up such errors:
javac AllFiles.javaAllFiles.java:174: cannot find symbol
symbol : variable Bob
location : class filesmanager.AllFiles
Bob.getItem(itemRef);
Where Bob is an example of another class. Even though I can say, compile Bob on it's own as it doesnt have any such reference.
I've tried:
javac -cp "C:\Program Files\Java\jdk1.6.0_02\bin" AllFiles.javaThis also failed.
Any ideas?

I've tried spoon_'s suggestion, but I'm still getting the error ("cannot find symbol"). Here is my code:
File Hello/Fred.java:
package Hello;
public class Fred
    public int age;
    public Fred()
        this.age = 1;
} // public class FredFile Hello/Hello.java:

public class Hello
    public static void main(String args[])
        Fred fred = new Fred();
        System.out.println("Fred is " + fred.age);
} // public class HelloAnd here is my attempt to compile Fred.java and Hello.java:
C:/Users/levner/programs[219]javac -cp c:\users\levner\programs\hello Hello\Fred.java
C:/Users/levner/programs[220]javac -cp c:\users\levner\programs\hello Hello\Hello.java

The system cannot find the path specified - Problems

I am having an issue that I am hoping someone can help figure out for me.
I am currently learning Java, and am working with the Beginning Programming with Java for Dummies book second edition. I have downloaded and am running the Java 6 program and am using the JCreator 3.5Pro that was recommended to run the Practice files for the Dummies book.
I have the practice files here:
C/Program Files/Xinox Software/JCreatorV3/My Projects
While trying to compile one of the practice files, I get this error message:
--------------------Configuration: MyNewProject - JDK version 1.6.0_21 <Default> - <Default>--------------------
javac: file not found: src_mynewproject.txt (The system cannot find the path specified)
Process completed.
**When I try to execute, I get this error message:**
--------------------Configuration: MyNewProject - JDK version 1.6.0_21 <Default> - <Default>--------------------

Could not find the main class: EchoLine. Program will exit.
Exception in thread "main"
Process completed.
When I set up the new file, and the new class, I confirmed the file path.
I know most people will ask if I am absolutely certain I put in the code in properly, and yes I did. It was a matter of copying word for word, and punctuation. I did it 100% correctly. About 12 times. I have NO idea what this means, but I would REALLY REALLY appreciate any help on this.
Please keep in mind, I am slightly clueless, and really need to have any help dumbed down a bit. Lol.
As a side note, this isn't my first project, and I haven't had this problem before now.
thanks in advance. =)

So I wanted to clarify what I've done a bit more since I decided to redownload the dummies programs for the program and try again.
I will try to list my steps in order of what I did and see if I've gone wrong somewhere along the line.
I downloaded my project files from here: http://ca.dummies.com/store/product/Beginning-Programming-with-Java-For-Dummies-2nd-Edition.productCd-0764588745,navId-322469,descCd-DOWNLOAD.html
I unzipped them this time here: C:\Program Files\Java\jdk1.6.0_21\MyProjects\
I opened JCreator 3.5 and starting fresh, with all previous projects deleted and clicked on "Open Workspace". I chose "MyWorkspace.jcw". Right clicked MyWorkspace and chose "Add new Project" and then chose "Empty Project". As per the books instruction for the first project, I named it "MyFirstProject". My file path was: C:\Program Files\Java\jdk1.6.0_21\MyProjects\MyFirstProject. Which is where I upzipped the files. I added it to current workspace and clicked finish.
I then added a new class. As per the books instructions, I right clicked "MyFirstProject" and selected Add New Class. For the name, I used MyFirstJavaClass, which is what the book told me to do. My locations are the exact same as above. and I clicked on Generate new Method, as it told me to. Which it doesn't in the next few lessons, so I know this has nothing to do with it. For that and a few other reasons. Lol.
I clicked on Finish.
All I had to do was replace a single line of code. Not type it all in this time.
Here is what shows up on the screen:
class MyFirstJavaClass {
     * Method main
     * @param args
     public static void main(String[] args) {
          // TODO: Add your code here
I need to change the : // TODO: Add your code here
with the line:
System.out.println.("Chocolate, royalties, sleep");
When I do this, and compile project, I get this:
--------------------Configuration: MyFirstProject - JDK version 1.6.0_21 <Default> - <Default>--------------------
javac: file not found: src_myfirstproject.txt (The system cannot find the path specified)
Process completed.
AGAIN! But it worked a few days ago.
And when I execute, I get this:
--------------------Configuration: MyFirstProject - JDK version 1.6.0_21 <Default> - <Default>--------------------

Can't get "Simple Example Doclet" to run -- Cannot find

I am trying to run the "Simple Example Doclet" at http://java.sun.com/j2se/1.3/docs/tooldocs/javadoc/overview.html.
It appears to compile ok, but when I go to run it I get the message "javadoc: Cannot find doclet class ListClass".
Listed below is:
     1. The execution command and error message
     2. The version (output of javadoc -J-version)
     3. The javac compile command and input and output files
All directories have been kept the same as in the example.
Any help would be appreciated.
Thanks
1. C:\jdk1.3>javadoc -doclet ListClass -classpath C:\jdk1.3\lib\tools.jar MyClass.java
javadoc: Cannot find doclet class ListClass
1 error
2. javadoc -J-version
     gives
          java version "1.3.1_01"
          Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
          Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode).
3. javac -classpath C:\jdk1.3\lib\tools.jar ListClass.java
     appears to give good compile ....
          e. g. Input source file ListClass.java is as follows:
               import com.sun.javadoc.*;
               public class ListClass {
               public static boolean start(RootDoc root) {
               ClassDoc[] classes = root.classes();
               for (int i = 0; i < classes.length; ++i) {
               System.out.println(classes);
               return true;
          and.....
          decompiled ListClass.class file is as follows:
               // Decompiled by DJ v2.8.8.54 Copyright 2000 Atanas Neshkov Date: 10/11/2001 4:09:46 PM

               // Decompiler options: packimports(3)
               // Source File Name: ListClass.java
               import com.sun.javadoc.RootDoc;
               import java.io.PrintStream;
               public class ListClass
               public ListClass()
               public static boolean start(RootDoc rootdoc)
               com.sun.javadoc.ClassDoc aclassdoc[] = rootdoc.classes();
               for(int i = 0; i < aclassdoc.length; i++)
               System.out.println(aclassdoc[i]);
               return true;

Sorry to be so late in getting back to you .. I was on vacation.
ListClass is in the current directory. I did get it to work however... In order to get it to work I had to do two things:
1. use -docletpath (even thought it was in the current path) e. g. -docletpath C:\jdk1.3\ListClass.jar
AND
2. Make the class file a jar file -- I could not get it to work otherwise.
p.s. the typo was a decompiler error.

I can't find "javac"

I am having a hard time fixing this problem. I downloaded JDK 1.6.0_22 and I am using Windows Vista Home Premium edition and when I try to run the "javac HelloWorlApp.java" I get the error: 'javac' is not recognized as an internal or external command, operable program or batch file
I went back and read the directions and also the troubleshooting page with a similar example and created this path:
To set the PATH permanently, add the full path of the jdk1.6.0_<version>\bin directory to the PATH variable. Typically this full path looks something like C:\Program Files\Java\jdk1.6.0_<version>\bin. Set the PATH as follows on Microsoft Windows:
1.Click Start > Control Panel > System on Windows XP or Start > Settings > Control Panel > System on Windows 2000.
2.Click Advanced > Environment Variables.
3.Add the location of bin folder of JDK installation for PATH in User Variables and System Variables. A typical value for PATH is:
C:\Program Files\Java\jdk1.6.0_<version>\bin
I still can't find/run the "javac" command but the computer cannot find it.
Any advice? Thanks...
Richard.

Hi guys, thanks for the information. I removed the files I added to the bin folder and put them back in my documents. I followed the instructions here:
http://download.oracle.com/javase/tutorial/getStarted/cupojava/win32.html#win32-2b
and I can't run "javac" from the java directory. It gives me the same error. I copied what I get from the command screen here:

After this I went to the troubleshooting section and tried to update the PATH in the Variable Environment.
Kate, you asked what I put in step three, here it is:
In the variable environment I found two boxes: the user variables and the system variables. I clicked "NEW" in the user section and a box came up with two fields:
1- variable name: javac
2- variable value: C:\Program Files\Java\jdk1.6.0_22\bin then I repeated the same steps in the System variable.
Any ideas or recommendations?
Thanks again for all the help!!
Richard.

"Cannot find the main Class. Program will exit."

Hi, I created a program, and I am trying to distribute it to other people in my office. I tried using both NetBeans 6.8/6.9 and eclipse. I exported to a single jar file. When I run this single .jar file, it runs perfectly. I sent it to one of my coworkers, and the message "Cannot find the main Class. Program will exit." popped up. I then had IT update his Java to 6.20 and it worked. The problem is that this program must be distributed to over 100 people, and I cannot have them each update their Java individually, nor will IT update everyone's on their own. They all have Java 4.XX I believe. Is there any way around this error that only happens on older versions of java? I have checked my manifest file and what not, as I said it runs on computers with Java 6.

a) Ensure the code does not use functionality introduced in later versions, e.g. assertions, generics, for-each loops.. Using the [cross-compilation options of javac|http://java.sun.com/javase/6/docs/technotes/tools/windows/javac.html#crosscomp-options] will warn of those.
b) Ensure the code does not use any classes, attributes or methods that were not available in the earlier version, then use the cross-compilation options of javac when compiling. Actually the second will alert of the first, so long as the -bootclasspath parameter is used with an appropriate rt.jar.I believe that everything is ok, unless some of the swing functions cannot be used in 1.4. Besides the swing functions (which I am not sure about) everything should be able to be used in 1.4
Thank You

Cannot find symbol : class ! problem

Hello,
I have 2 java files (CD.java & CDCatalog.java) in a package called "testPackage". I can compile CD.java, but CDCatalog.java (that creates CD instances) gives following error - cannot find symbol symbol : class CD
Below are the 2 files, please tell me why I get this errors , thanks!
1) CDCatalog.java
package testPackages;
import java.util.Hashtable;
//import testPackages.CD;
public class CDCatalog {
/** The CDs, by title */
private Hashtable catalog;
public CDCatalog( ) {
catalog = new Hashtable( );
// Seed the catalog
addCD(new CD("Nickel Creek", "Nickel Creek", "Sugar Hill"));
addCD(new CD("Let it Fall", "Sean Watkins", "Sugar Hill"));
addCD(new CD("Aerial Boundaries", "Michael Hedges", "Windham Hill"));
addCD(new CD("Taproot", "Michael Hedges", "Windham Hill"));
public void addCD(CD cd) {
if (cd == null) {
throw new IllegalArgumentException("The CD object cannot be null.");
catalog.put(cd.getTitle( ), cd);
2) CD.java
package testPackages;
public class CD {
private String title;
private String artist;
private String label;
public CD( ) {
// Default constructor
public CD(String title, String artist, String label) {
this.title = title;
this.artist = artist;
this.label = label;
public String getTitle( ) {
return title;
public void setTitle(String title) {
this.title = title;
public String getArtist( ) {
return artist;
public void setArtist(String artist) {
this.artist = artist;
public String getLabel( ) {
return label;
public void setLabel(String label) {
this.label = label;
public String toString( ) {
return "'" + title + "' by " + artist + ", on " +
label;
}

just tried it as well, no problems, provided you
compile CD.java firstI just tried from the shell ans look at this...

E:\testPackages>I am now officially confused. I even specified the exact path to the CD.class file and javac still didnt like it.
I'll dig some more. It has to be related to the classpath some how..

Still Stumped.. I'll sleep on it..

Actually, you have NO CLUE what he's trying to doActually he said what he is trying to do in his posting. It's no mystery. But that's all the information that's available. If you know something that isn't posted here why not say so?
Your reply was a snide, rude, "You're stupid for doing it that way" answerMy reply was neither snide nor rude and implied none of what you impute to it. It was a proper and constructive suggestion. You are entitled to disagree with it, but that doesn't justify this immoderate outburst.
Bottom line is, you chose to be nastyBottom line is you're just making this up. You are imputing motives to me without evidence. Don't do that.
You are the type of person that makes searching forums and posting questions for assistance a near waste of time.I doubt that you'll find many regulars here that would agree with that assertion. When you have made over 16,000 posts here over ten years as I have, come back and we'll discuss it some more.
Go back to grade school and ...I suggest you try it yourself. You're not adding anything except noise to the discussion. Try curbing your temper, and while you're at it have a good look at the Code of Conduct for these forums. You're verging on personal abuse here.
And, additionally, I've used ANT in the past. Batch files are FAR AND AWAY easier to set up.In your opinion. I disagree entirely, and I have eleven years' experience with Java to back it up.
As for CLASSPATH, I haven't done anything about setting it beyond installing the JDK since about 1999, and it has a dot in it as we speak.

Need help with class info and cannot find symbol error.

I having problems with a cannot find symbol error. I cant seem to figure it out.
I have about 12 of them in a program I am trying to do. I was wondering if anyone could help me out?
Here is some code I am working on:
// This will test the invoice class application.
// This program involves a hardware store's invoice.
//import java.util.*;
public class InvoiceTest
     public static void main( String args[] )
     Invoice invoice1 = new Invoice( "1234", "Hammer", 2, 14.95 );
// display invoice1
     System.out.println("Original invoice information" );
     System.out.println("Part number: ", invoice1.getPartNumber() );
     System.out.println("Description: ", invoice1.getPartDescription() );
     System.out.println("Quantity: ", invoice1.getQuantity() );
     System.out.println("Price: ", invoice1.getPricePerItem() );
     System.out.println("Invoice amount: ", invoice1.getInvoiceAmount() );
// change invoice1's data
     invoice1.setPartNumber( "001234" );
     invoice1.setPartDescription( "Yellow Hammer" );
     invoice1.setQuantity( 3 );
     invoice1.setPricePerItem( 19.49 );
// display invoice1 with new data
     System.out.println("Updated invoice information" );
     System.out.println("Part number: ", invoice1.getPartNumber() );
     System.out.println("Description: ", invoice1.getPartDescription() );
     System.out.println("Quantity: ", invoice1.getQuantity() );
     System.out.println("Price: ", invoice1.getPricePerItem() );
     System.out.println("Invoice amount: ", invoice1.getInvoiceAmount() );
and that uses this class file:
public class Invoice
private String partNumber;
private String partDescription;
private int quantityPurchased;
private double pricePerItem;
     public Invoice( String ID, String desc, int purchased, double price )
          partNumber = ID;
     partDescription = desc;
     if ( purchased >= 0 )
     quantityPurchased = purchased;
     if ( price > 0 )
     pricePerItem = price;
public double getInvoiceAmount()
     return quantityPurchased * pricePerItem;
public void setPartNumber( String newNumber )
     partNumber = newNumber;
     System.out.println(partDescription+" has changed to part "+newNumber);
public String getPartNumber()
     return partNumber;
public void setDescription( String newDescription )
     System.out.printf("%s now refers to %s, not %s.\n",
partNumber, newDescription, partDescription);
     partDescription = newDescription;
public String getDescription()
     return partDescription;
public void setPricePerItem( double newPrice )
     if ( newPrice > 0 )
pricePerItem = newPrice;
public double getPricePerItem()
return pricePerItem;
Any tips for helping me out?

System.out.println("Part number:
"+invoice1.getPartNumber;
The + sign will concatenate invoice1.getPartNumber()
after "Part number: " forming only one String.I added the plus sign and it gives me more errors:

Inheritance - Cannot find Symbol

Hello!
After many hours of searching for the answer, i have decided to brave getting a grilling for asking something trivial.
I'm creatating a system and so far the problem i am having is inheritance.
The superclass compiles fine, no problems:
package Boats;
public abstract class Boat
     protected String name;
     protected int price;
     protected int id;
     protected String type;
     protected boolean hire;
     public boat(int boatID, String boatName, int cost, String boatType)
        name = boatName;
          price = cost;
          id = boatID;
          type = boatType;
        hire = false;
}however, the subclass of pedal boat won't compile:
package Boats;
public abstract class PedalBoat extends Boat
     private String colour;
    public PedalBoat(int id, String boatName, int cost, String boatType, String c)
        super(id, boatName, cost, boatType);
          colour = c;
        super.hire = false;
}both of these class files are in the same folder 'Boats', but when i compile PedalBoat, the following message is displayed:
"PedalBoat.java:2: cannot find symbol
symbol: class Boat
public abstract class PedalBoat extends Boat
^
Any thoughts or help or links to anywhere that has answered this before?
Thanks!

You'll want the following directory structure. The C:\projects part is arbitrary. It's what comes after it that matters.
C:\projects\Boats\Boat.java
C:\projects\Boats\PedalBoat.javaThen, CD to C:\projects, and execute
javac -cp . Boats/*.javaAs a side note, to go with the flow convention-wise, I'd suggest renaming your Boats package to boats. Package names are conventionally all lowercase.

Servlet cannot find Bean

I am trying to access a java bean through a servlet..
the bean is defined in the package com.mycomp
when i use this bean using test.jsp it works fine it finds the package com.mycomp.. but when i am using the Servlet it cannot find the package...when i am trying to compile the servlet it says it cannot resolve the symbol class ConnectionBean
it cannot find the package com.mycomp
your help will be appreciatied....
here is the structure of files:
tomcat
webapps
myapp
jsp
-test.jsp
WEB-INF
classes
-PropertyServlet.java
-PropertyServlet.class
-ConnectionBean.java
com
mycomp
-ConnectionBean.class
I have tried importing in the servlet import com.mycomp.*; but i still get an error com.mycomp not found...
I have also tried importing the class itself by import com.mycomp.ConnectionBean;
I still get the package com.mycomp not found;
is there any xml file or anything that i need to edit so servlets can read the packages located in classes folder?

me also same problem...
this class path is included in server itself..
or we can set during compiling time...
then this is my compile.bat file please check
set classpath=%CLASSPATH%; ./WEB-INF/classes;
@echo off
javac -d ./WEB-INF/classes/ ./dev/beans/*.java
javac -d ./WEB-INF/classes/ ./dev/ContentManagement/beans/*.java
javac -d ./WEB-INF/classes/ ./dev/servlets/*.java
and my servlet file like this below..
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import com.deploy.servlet.*;
public class ControlServlet extends HttpServlet
     public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException,IOException
          response.setContentType("text/html");
          PrintWriter out = response.getWriter();
          out.println("Testing");
/*          if (request.getParameter("pageName")=="CEOSpeak")
               CEOBean CB = new CEOBean();
               if (request.getParameter("actionType")=="add")
               else if (request.getParameter("actionType")=="edit")
               else if (request.getParameter("actionType")=="delete")
                    if(CB.deleteCEO(request.getParameter("CEOId")))
                         response.sendRedirect("CEO_Speaks.jsp");
