2 files in same package need import package??

test1.java and test2.java are in the same package mypackage,
and test1.java will call methods in test2.java, does it mean
test1.java needs to import mypackage.test2;
Because I found sometimes it won't compile test1.java without import mypackage.test2..
i.e.
//test1.java
package mypackage;
import mypackage.test2;
class test1

You shouldn't need to import a class that lies in the same package.

Log4J - file appender (2/more file for same package/class)

Hi All,
My requirement is i want to create 2 log file for same package.
EG: com.foo.bar
my code:
log4j.rootCategory= ALL, fileAppender,stdout
log4j.appender.fileAppender=org.apache.log4j.RollingFileAppender
log4j.appender.fileAppender.File=c:\\temp\\test.log
log4j.appender.fileAppender.MaxFileSize=64KB
log4j.appender.fileAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.file1=org.apache.log4j.RollingFileAppender
log4j.appender.file1.File= file1.log
log4j.appender.file1.MaxFileSize=64KB
log4j.appender.file1.MaxBackupIndex=1
log4j.appender.file1.layout=org.apache.log4j.PatternLayout
log4j.appender.file1.layout.ConversionPattern=%p %t %c - %m%n
log4j.appender.file2=org.apache.log4j.RollingFileAppender
log4j.appender.file2.File= file2.log
log4j.appender.file2.MaxFileSize=64KB
log4j.appender.file2.MaxBackupIndex=1
log4j.appender.file2.layout=org.apache.log4j.PatternLayout
log4j.appender.file2.layout.ConversionPattern=%p %t %c - %m%n
log4j.appender.file3=org.apache.log4j.RollingFileAppender
log4j.appender.file3.File= file3.log
log4j.appender.file3.MaxFileSize=64KB
log4j.appender.file3.MaxBackupIndex=1
log4j.appender.file3.layout=org.apache.log4j.PatternLayout
log4j.appender.file3.layout.ConversionPattern=%p %t %c - %m%n
// THIS IS FOR ClIENT
log4j.logger.com.ls.es.service=DEBUG, file1
// THIS IS FOR SUPPORT
log4j.logger.com.ls.es.service=DEBUG, file2
// THIS IS ERROR MESSAGE
log4j.logger.com.ls.es.service=ERROR, file3
Here file1 is for Client(Client Admin)and file2 is for Support.
but am getting only file3.log file which is for Error Message..
some where configuration is missing...
Thanks,

I have created a class that allow to create easily new logs:
1.- Switch the Root Logger output
2.- Create as many logs as desired (I build a simple web server, each new client has a log associated to it).
Main problem: code and comments in spanish.
Are you intereseted on it? Let me know, I can send it to you by mail.

2 files in same package and depends each other need import package??

test1.java and test2.java are in the same package mypackage,
and test1.java will call methods in test2.java, does it mean
test1.java needs to import mypackage.test2;
i.e.
//test1.java
package mypackage;
import mypackage.test2;
class test1
}

no, once classes are in the same packages they are picked up ie tc1 is in tc_package and tc2 is also in tc_package, tc1 need not import tc_package.tc2 to use tc2 methods.

Cannot find class in same package but in different file

I have following two source files. Both the file has same package statement as below
package java.buron.doeacc ;
But whenever i try to compile File: shoepolish.java ( mainfram.java compiled succesfully before)
following error message appear
..\..\buron\doeacc\shoepolish.java:12: cannot resolve symbol
symbol : class MainFrame
location: class java.buron.doeacc.shoepolish
          MainFrame mainFrame = new MainFrame();
^
..\..\buron\doeacc\shoepolish.java:12: cannot resolve symbol
symbol : class MainFrame
location: class java.buron.doeacc.shoepolish
          MainFrame mainFrame = new MainFrame();
^
Please tell me What is the problem and how it can be solved.
why cannot find the class that are in same package.
I have JDK 1.3
FOLLOWING ARE THE TWO FILES

The javac compiler uses the Classpath to find classes. If your directory structure is c:\myjava\buron\doeacc (for example) then you need to have c:\myjava in the Classpath when you compile. For example javac -classpath c:\myjava MainFrame.java

Class.forname - Unable to load class if two jars with same package name

class.forname - Unable to load class if two jars contains same package name exists in classpath.
JVM is stopping search for class one it finds the package name in the jar file that is ahead in classpath,
JVM is not continuing search in the remaining jar files.
For this , I put the jar file that contained class ahead of of ther jar file containing same package name, then it worked.
Is this a JVM bug ? (JDK 1.5)

I reported as bug to sun. I got auto email, looks they have not assigned any Bug ID so far.

Importing a .class file into my package?

Hi. I'm making a java program but I need to use an external .class file to get variables and use methods from. Is it possible to "import" a class file into my package to be able to do so?
Thanks

Basically, for our last project we created a class
that held the information about a year: how many days
were in a month, how many months were in a year, etc.
etc. For this project, we'll be having to use that
same class to make a GUI calendar. Our teacher
provided a class which he compiled for us to use in
our projects incase our previous class had some flaws
in it, which mine did. Unfortunately, it's in .class
format and I don't know how to use it in my package!That's going to be a problem then. I would assume that it is going to have an API like your old one did. Same name and same methods etc. So do you know what the name and method signatures of your class were supposed to be?

Running file in the same package problem

I have 2 java file packed in the same package:
DBConnection.classpackage main;
import java.sql.*;
public class DBConnection {
}t1.class
package main;
import main.DBConnection;
import java.util.ArrayList;
import java.util.regex.Pattern;
import java.util.regex.Matcher;
import java.sql.*;
public class t1 {
}They are packed in the same directory, the path is:
D:\java\project1\main\DBConnection.class
D:\java\project1\main\t1.class
When i was in command prompt (window), I tried both of these but encounterd the following error
D:\java\project1\main>java t1
D:\java\project1\main>java -cp D:\java\project1\main t1
I encountered the following errors:
Exception in thread "main" java.lang.NoClassDefFoundError: t1 (wrong name: main/t1)
When I tried:
D:\java\project1\main>java -cp D:\java\project1 t1
I got this error:
Exception in thread "main" java.lang.NoClassDefFoundError: t1
Can anyone tell me the reason? Thx.

package main;
import main.DBConnection;You don't need to import a class in the same package.

Error: A file found in a source-path must have the same package structure

I use Adobe Flex Compiler (mxmlc) Version 4.1.0 build 16032,I have a file,named CustomGraphContainerController.as,it's directory is c:\controllers,and the GCController.as file is under the same directory,CustomGraphContainerController.as file like follows
package controllers{
import ui.GraphControlContainer;
public class CustomGraphContainerController extends GCController {
public function CustomGraphContainerController(a_graphControlContainer:GraphControlContainer) {
super(a_graphControlContainer);
Then I want to use mxmlc command to compile it,like follows:
C:\>mxmlc c:\controllers\CustomGraphContainerController.as
But it raise compile errors,like follows:
Loading configuration file C:\sdk\frameworks\flex-config.xml
C:\controllers\GCController.as: Error: A file found in a source-path must have the same package structure '', as the definition's package, 'controllers'.
I don't know how to compile the as file with package controllers? Where is wrong? How to use mxmlc to compile it?
Thanks

HI,
You should have one main application class to compile this as code to swf.. So that main application path should be in your proper package structure.. then you can compile you app and as files also...

How do I load a properties file that is in the same package?

I have the following package:
com.company.ldap
In the package I have:
main.java
settings.properties
I want to load the values in the settings.properties file in code, such as:
propertiesFile = "settings.properties";
        try {
            properties.load(new FileInputStream(new File(propertiesFile)));
        } catch (IOException e) {
            ... error logging logic ...
        }I keep returning "The system cannot find the file specified".
How do I properly load a properties file in a class file within the same package?
Thanks,
--Todd

Put the file in the classpath (such as in the parent directory of com/company/ldap). Then obtain an input stream to that file like this:
InputStream stream = getClass().getResourceAsStream("/settings.properties");
Then use that stream in the properties.load method. Remember to close the stream as well.

Java file cannot access other class in same package???????

I have written a bean as follows-------
package CustTags;
public class TomMovieBean
     private String movieName;
     private String movieDirector;
     public void setmovieName(String movieName)
          this.movieName = movieName;
     public String getmovieName()
          return this.movieName;
     public void setmovieDirector(String movieDirector)
          this.movieDirector = movieDirector;
     public String getmovieDirector()
          return this.movieDirector;
Now i am writing a tag handler for my JSP custom tag as follows----------
package CustTags;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
import java.util.*;
public class Dynamic extends TagSupport
     private List movieList;
     public void setmovieList(List movieList)
          this.movieList = movieList;
     public int doStartTag() throws JspException
          Iterator iterator = movieList.iterator();
          TomMovieBean TMBObj = null;
          try
               JspWriter out = pageContext.getOut();
               while(iterator.hasNext())
                    TMBobj = (TomMovieBean)iterator.next();
                    String movieName = (String)TMBObj.getmovieName();
                    String movieDirector = (String)TMBObj.getmovieDirector();
                    out.println(movieName+"...."+movieDirector+"<br>");
          }catch(Exception ex)
               throw new JspException("Error in doStartTag()");
          return SKIP_BODY;
Now when i compile Dynamic.java it shows foll. errors
Dynamic.java:19: cannot resolve symbol
symbol : class TomMovieBean
location: class CustTags.Dynamic
TomMovieBean TMBObj = null;
^
Dynamic.java:27: cannot resolve symbol
symbol : variable TMBobj
location: class CustTags.Dynamic
TMBobj = (TomMovieBean)iterator.next();
^
Dynamic.java:27: cannot resolve symbol
symbol : class TomMovieBean
location: class CustTags.Dynamic
TMBobj = (TomMovieBean)iterator.next();
^
3 errors
I am unable to comprehend why it can't recognize TomMovieBean despite the fact that its a public class and in the same package as that of Dynamic.java

Is your classpath set correctly? I.e. does it point to the directory containing the CustTags directory?
BTW, by convention, package names are written in lower case.

How to access a class file outside the package?

created a two java files Counter.java and TestCounter.java as shown below:
public class Counter
     public void print()
          System.out.println("counter");
package foo;
public class TestCounter
     public static void main(String args[])
          Counter c = new Counter();
          c.print();
Both these files are stored under "D:\Test". I first compiled Counter.java and got Counter.class which resides in folder "D:\Test"
when i compile TestCounter.java i got the following error message:
D:\Test>javac -classpath "d:\Test" -d "d:\Test" TestCounter.java
TestCounter.java:6: cannot find symbol
symbol : class Counter
location: class foo.TestCounter
Counter c = new Counter();
^
TestCounter.java:6: cannot find symbol
symbol : class Counter
location: class foo.TestCounter
Counter c = new Counter();
^
2 errors
what could be the problem. Is it possible to access a class file outside the package?

ya that's fine..if we have two java files where both resides in the same package works fine or two java files which donot have a package statement also works fine. But my doubt is, i have a Counter.class which does not reside in a package and i have a TestCounter.class which resides in a package "foo", in such a scenario, how do i tell to the compiler that "Counter.class resides in such a path, please look at that and give me TestCounter.class". i cannot use import statement to import Counter.class in TestCounter.java because i donot have a package for Counter.java.

Problem:
I upgraded Leopard to Snow Leopard. Everything worked fine for a month. To free up disk space I deleted some of the iPhoto flders (modfied and original images). Everything worked still fine. Shut down the computer. Next day it was incredibly slow. At the same time the indexing was running. I stopped indexing, but stll slow. Every operation took minutes. I tried all the tricks that I found in the internet (repaired file permissions, repaired disk, cleared PRAM , moved big filed from desktop, etc.). After 24 full hours of trying all this I decided to erase the hard drive and reinstall, directly from the Snow Leopard Install disk, but it fails after downloading the packages. Below is the part of the log. Then I tried to use the old Leopard install DVD to reinstall Leopard, it then sais estimated time 12 hours or so and eventually crashed, spitting out a lot of "reportcrash" in the log. What is going on? I'm running out of options. Any advice? Would zeroing the hard drive help? If nothing else I plan to buy a new hard drive, since the only explanation I have is that there is a problem with the hard driven although the disk utility says it is OK. I need a bigger one anyway. Any ideas? Thank you!

It sounds to me like your Internal Hard Drive is failing.
I recommend you buy a new one, that is a good candidate for replacing the old one, but install it in an External enclosure and Install a fresh Mac OS X on it from the DVD. You can boot your Mac from any attached drive.
The new System can be used to get some work done, check your emails, and takes the pressure off resolving this immediately. You can also attempt to salvage files off the old drive if needed.
Once things seem to be working, then move the new drive inside the computer. Failures at this point may be due to bad cable, which has been a problem in some of these MacBooks.
Use security erase, write Zeroes, one pass, to re-write every block on the old drive. Any block discovered to be bad will be replaced with spares the drive holds in reserve for this purpose. If more than 10 blocks are pared on one pass, "Initialization Failed!" will be the result. Although you can try the erase again, there is some question whether you want to trust this drive with your precious data.

Calling a method of one class from another withing the same package

hi,
i've some problem in calling a method of one class from another class within the same package.
for eg. if in Package mypack. i'm having 2 files, f1 and f2. i would like to call a method of f2 from f1(f1 is a servlet) . i donno exactly how to instantiate the object for f2. can anybody please help me in this regard.
Thank u in advance.
Regards,
Fazli

This is what my exact problem.
i've created a bean (DataBean) to access the database. i'm having a servlet program (ShopBook). now to check some details over there in the database from the servlet i'm in need to use a method in the DataBean.
both ShopBook.java and DataBean.java lies in the package shoppack.
in ShopBook i tried to instantiate the object to DataBean as
DataBean db = new DataBean();
it shows the compiler error, unable to resolve symbol DataBean.
note:
first i compiled DataBean.java, it got compiled perfectly and the class file resides inside the shoppack.
when i'm trying to compile the ShopBook its telling this error.
hope i'm clear in explaining my problem. can u please help me?
thank u in advance.
regards,
Fazli

Error creating instance of class from same package

When I try to create an instance of a class that is in the same package, my IDE indicates that the constructor can not be found. Can anyone tell me what is wrong? Thanks. Below are the codes for both classes:
package com.practice;
import java.applet.*;
import java.awt.*;
import javax.swing.*;
public class WebProject extends Applet{
     public void init(){
                // The following line is where the IDE indicates there is an error
          UserInterface gui = new UserInterface();
     } // end init()
     public void start(){
     } // end start()
     public void stop(){
     } // end stop()
     public void destroy(){
     } // end destory()
} // end class
package com.practice;
import java.applet.*;
import java.awt.*;
import javax.swing.*;
public class UserInterface extends Applet{
     JPanel menuPanel = new JPanel();
     JPanel contentPanel = new JPanel();
     JPanel savePanel = new JPanel();
     ImageIcon saveIcon = new ImageIcon("workspace/images/toolbarButtongraphics/general/Save24");
     JButton saveButton = new JButton("Save", saveIcon);
     public UserInterface(){
          savePanel.add(saveButton);
          setLayout(new BorderLayout());
          add(menuPanel, BorderLayout.NORTH);
          add(contentPanel, BorderLayout.CENTER);
          add(savePanel, BorderLayout.SOUTH);
} // end UserInterface class

Thanks for the explanation and example. At first, I didn't understand what you were getting at, but after reading "Using Top-Level Containers" and "How to Use Root Panes" java tutorials it made much more sense. Unfortunately, the books I've read up to this point, did not cover those topics at all. The books simply stated that the first step in creating a Swing gui was to extend the JFrame, or JApplet, or etc.
Unfortunately, my original problem persists. I continue to get compile-time errors such as:
TestUserInterface.java:5: cannot find symbol
symbol: class UserInterface
location: class projects.web.TestUserInterface
                      UserInterface ui = new UserInterface(); Anyone know why?
Both the classes are in the same named packaged. Below is my code:
package projects.web;
import java.awt.*;
import javax.swing.*;
public class UserInterface extends JFrame{
     JPanel menuPanel = new JPanel();
     JPanel contentPanel = new JPanel();
     JPanel selectionPanel = new JPanel();
     JButton save = new JButton("Save");
     JButton addFiles = new JButton("Add");
     public UserInterface(){
     super("File Upload");
     setSize(500, 500);
     menuPanel.add(addFiles);
     selectionPanel.add(save);
     setLayout(new BorderLayout());
     add(menuPanel, BorderLayout.NORTH);
     add(contentPanel, BorderLayout.CENTER);
     add(selectionPanel, BorderLayout.SOUTH);
     } // end constructor
} // end UserInterface class
package projects.web;
public class TestUserInterface{
     public static void main(String[] args){
          UserInterface ui = new UserInterface();
} // end TestUserInterface class

Unable To Include Files In iOS Package

Hi,
I an using the latest release version of Flash Builder, trying to package an app for the iPad. I have an AIR application that I created to run on a desktop, and have modified it to run on the iPad. It works fine, however I cannot package the need resource files it uses, such as jpg, xml, swf, and flv files within the ipa file using Flash Builder. It seems that if I select more than 30-40 of these types of files to include, Flash Builder will not compile the ipa file without some sort of error, the most common one talks about:
"Cannot run program "java.exe" (in directory "C\Users\lee\AppData\Local\Temp\AOT1308010984915"): CreateProcess error=206, The filename or extension is too long"
Now I am guessing that Flash Builder is appending all of my selected files to a command line string or something somewhere, and so it can't handle that long of string on the command line. If I stick to less than 30 files, it works fine, but if I try and the 1000 or so files that I need to, it will not work.
This app would never be in the app store, but rather on internal company iPads. The reason for so many files is the number of products the app covers, and the number of languages it supports. So yes the ipa file would be about 500Mb, but that should not be an issue, since an ipa file is basically a zipped archive. I think this is a bug though in Flash Builder; the program also becomes unresponsive when trying to access the include file list located in Project Properties -> ActionScript Build Packaging -> Apple iOS settings dialog. It make take several minutes before FB becomes responsive again when working with this number of files.
Does anyone have any suggestions?
thanks

Hello,
Since I first encountered this bug, I have always had my asset files in
subfolders. See the attached screen shot. This is my project folder, and
every subfolder is included except for the com folder, which for some
reason FB copied into the bin directory on it's own.
So I do not think this fixed. In this report, they are not using the same
number of files as I am, so it is possible that this only works with a low
number of files.
