Compiler says that package does not exist...why??

I have a directory called myutil, and inside that, a class "PrintTeste". Out of package, one class called "Teste"...
See the code:
public class Teste {   
    /** Creates a new instance of Teste */
    public Teste(){
        myutil.PrintTeste.mPrint();
    public static void main(String []args){
        Teste teste = new Teste();
inside package myutil:
package myutil;
public class PrintTeste { 
    public static void mPrint(){
        System.out.print("teste ");
}using javac myutil/PrintTeste.java.... it's ok
But, when I try compile using javac Teste.java I receive the following message:
Teste.java:8: package myutil does not exist
myutil.PrintTeste.mPrint();
^
Using Netbeans 5.5, this error does not occur.
My environment variables CLASSPATH, JAVA_HOME AND PATH were right setted...I'm using Windows XP, jsdk 1.5.0_07
So, what could be happening?
Thank for yout help!

Fortunatly, the compile process ocurres well using:
javac -classpath . myutil/TestePrint.java
and
javac -classpath . Teste.java
but when I try run the class Teste, another error:
java Teste
Exception in trhead "main" java.lang.NoClassDefFoundError: Teste/class

  • Package does not exist when compile in Jgrasp 1.8.3

    I have a package called jpb stored in a folder called jpb. The package has two files SimpleIO.java and Convert.java. My program has 1 of the line like this
    import jpb.*;
    I put the path and classpath in Jgraps pointing to the folder jpb but when I compile the program, it keeps saying the package does not exist. Even when i took all the files outside and place it in the same folder with the file that i am compiling. It says that bad class file. The heck?????????.
    Can some1 please help. I even made an autoexec.bat to set up the path to the folder and run it. it keeps saying the package does not exist.

    Classpaths reference things like jar files or directories that contain .class files. Change your classpath to have the .jar files.

    The thing I don't understand is the "comp.sap.examples.calculator.beans" class has already been included inside the EAR (I used my zip tool to check the EAR file and confirmed it's there), why did the compiler still complain that the package does not exist?  Any great guys & gals out there can help this poor newbie who spent the past 5 hours searching for Google for answers but couldn't find any??
    Thank you.
    Brian

    Perhaps I should give out more information about this problem.
    The EAR file contains a WAR file and a JAR file. 
    The WAR file contains a JSP and it contains codes to refer to a java proxy class of package comp.sap.examples.calculator.beans.CalcProxy.
    So it seems the compilation error is triggered when it tries to compile the WAR file.
    I checked the structure of the WAR file using a zip tool.
    At the base it contains this:
    WEB-INF (a folder)
    Calculator.jsp (the JSP file)
    Inside the WEB-INF folder is these:
    classes (a folder)
    web-j2ee-engine.xml
    web.xml
    Inside the classes folder is a tree of subfolders to describe the structure of the CalcProxy class:
    classes -> comp -> sap -> examples -> calculator -> beans -> CalcProxy.class
    So the java class file and the JSP file is in the same bundle of the WAR file.
    Why the compiler is not able to find the class file inside the JSP?

  • Urgent: Why org.apache.tomcat.* package does not exist?

    i am writing some programs about ldap
    my program code has used some packages as the followings
    import org.apache.tomcat.core.*;
    import org.apache.tomcat.util.*;
    import org.apache.tomcat.util.xml.*;
    i am using apache + tomcat4.1 server, jsdk1.4
    i have set the classpath that contains all the jar files in $TOMCAT_HOME\common\lib
    after setting the classpath, i compiled the code
    it said the above packages does not exist
    where should i find those packages?
    Aren't they in the tomcat i installed?
    PLX HELP

    for example, i want to use the class
    org.apache.tomcat.core.Context to create a class
    object.Then you would want to:
    import org.apache.tomcat.core.Context;
    -or-
    import org.apache.tomcat.core.*;
    Note how that is different than your original:
    import org.apache.tomcat.*;i just use as an example import org.apache.tomcat
    but i cannot find org.apache.tomcat.core or even any org.apache.tomcat.*
    so that means i havn't include the correct jar file in the classpath or no corresponding package are stored in the tomcat4.1
    i just want to know what jar file contains such stuff.
    i think it should be a silly problem. So there should be someone know it.

  • Java.math package does not exist!!!

    hi java experts, i really desperately need some help. ihave been trying to compile a java program i have written that imports the java.math package as i am using the BigInteger class. I am using SUN ONE STUDIO ME 4 and have j2se SDk installed. when i try to build the program in the IDE, it gives me an error message saying the java.math package does not exist. i can't understand why. i think it's an IDE problem. i tried mounting the filesystem and i mounted almost a million times in diff ways but it still can't compile. i can't find the directory of the java.math to mount into. anyway i tried to compile it at the command prompt and it can compile but with errors... so i figure that i do have the java.math class on my system just that the IDE jsut can't recognise it. i am at my wits end and gonna go mad if someone doesn't please help me.

  • Import statement reports 'package does not exist'

    I am seeing another odd error. I'm working on learning how to read and write to text files, and I have 2 errors reported, but one is obviously caused by the other. My package is labeled as such (copy>paste of package line):
    package michaelchristopherp4db;
    and the import line is this (copy>paste again):
    import michaelchristopherp4db.ProductRecord;
    However, Netbeans looks at the import and flags it red, saying package michaelchristopherp4db does not exist. this caused my line:
    ProductRecord product = new ProductRecord();
    to also be flagged in red as it cannot find the ProductRecord class. However, it has no problems with any of the product.get* method calls. Thank you in advance for any ideas or input.
    here is the full code of the file reporting the errors.

    I am embarrassed to admit this, but I am completely lost on the last question.. I have no clue wether it is a convenience for development or a dependancy, as I have not learned those terms or distinctions yet. For now I copied the ProductRecord file into my new project folder and renamed it's project line to match the new project name. However, while that eliminated the package does not exist error, and netbeans reports no errors now, when I run the program it does not write the new files. I have made some modifications to the code tryiing to get it to write properly but so far no luck in makingit work. Here is the current version of the file not running right.

  • Weird.. package does not exist

    I know this is a common question and i searched the forum but nothing there is what I need.
    First of all I have the 'main' source file under a directory: d:\Model1_SecurityService\
    There is a subdirectory securityservice, under which there are several other directories according to the packages I have.
    Another directory I have is: d:\Model1_Classes
    When I compile the main program from d:\Model1_SecurityService> typing the following: javac -d d:\Model1_Classes testmain.java
    When I do this, i get an error message saying package does not exist for each package I import in the main file.
    My classpath has d:\Model1_Classes in it and my path has .; etc.
    Anyone know what the problem is?
    Everything used to work but i continued working on another computer and after copying these changes to this one, i'm getting these errors...

    So, for example if you had a class Baz in package
    com.foo.bar and you're using d:\Model1_Classes as your
    root directory for your compiled code, then there
    should be a directory structure
    d:\Model1_Classes\com\foo\bar
    which contains the compiled class Baz.class. Is this
    what you have?yes
    I found the problem though, apperently i need . in my classpath as well; don't know why actually, but it works now.
    thanks for wanting to help though

  • Package does not exists

    Hai I want to use the package com.jscape.inet.ftp in my Java program. But when I imported it in my program and compiled , I got the error:- package com.jscape.inet.ftp does not exist Why? How can I use that package in my program? Any idea?

    Yes I am sure that my classpath is /opt/jdk1.5.0/bin as set in my .bash_profile. But when I gave the command echo $CLASSPATH it is showing only /opt/jdk1.5.0/ . Anyway I copied in both the locations and checked and it is not working. I copied the jar file to /opt/jdk1.5.0/lib also. Still there is no change! Any other suggestion?
    Thaks for your cooperation,

    Any pointers on this immediate problem? and is my book out of date?
    Many thanks,

    You downloaded the Java 2 SDK Standard Edition, but you need to also download the Enterprise Edition if you want to write programs that use enterprise features.

  • FTPClient Package does not exist?

    I have an FTP program. I'm trying to use this package. Here is a link to the class package overview:
    http://www.enterprisedt.com/downloads/ftp/doc/com/enterprisedt/net/ftp/FTPClient.html
    When I attempt to compile, I get the error that the package does not exist. I am importing these packages:
    import java.lang.Object.*;
    import java.lang.*;
    // This package causes the error
    import com.enterprisedt.net.ftp.FTPClient.*;
    Is there something I need to download, or some other package to import?
    Thanks,
    Logan

    Hi,
    I finally found the ftp.jar and downloaded it and put it in the /j2se/jre/lib/ext.
    I can now compile with this import line:
    import com.enterprisedt.net.ftp.*;
    Now my problem is trying to get this to work:
    String server = "192.168.1.100";
    String user = "logan";
    String passwd = "passwd";
    try {
    FTPClient ftp = new FTPClient(server);
    } catch (IOException ex) {
    System.out.println("Caught exception: "+ex.getMessage());
    But I get this error when compiling:
    unreported exception blah blah must be caught or declared to be thrown
    Thanks.

  • Imported package does not exist

    Hello
    I'm importing a package com.borland.jbcl.layout.* into my java
    program to do some GUI layout but kept getting the error that the package does not exist. Can someone explain why and the solution to this problem please?
    Thanks

    If the class you are trying to import is in a .jar file, you need to add the jar to your classpath CLASSPATH=c:\dir1\...\MyJar.jar. If the file is in a directory you need to include the base directory in the classpath CLASSPATH=c:\basedir
