Hi
I have a problem about packages.I am not sure whether I can discuss it in this
forum.But I am sending it anyway
I have two classes DebugWriter and ConnectionManager and an interface called
AppConstants in a package named Tbean.test.
When I am trying to compile ConnectionManager file , I am getting the following error
messages
ConnectionManager.java:10: cannot resolve symbol
symbol : class AppConstants
location: class Tbean.test.ConnectionManager
public class ConnectionManager implements AppConstants {
^
ConnectionManager.java:18: cannot resolve symbol
symbol : class DebugWriter
location: class Tbean.test.ConnectionManager
protected DebugWriter writer;
^
ConnectionManager.java:24: cannot resolve symbol
symbol : class DebugWriter
location: class Tbean.test.ConnectionManager
writer = new DebugWriter();
The source code for the three files is included here.These are very small files
Advance thanks
Regards
Sri
------------AppConstants.java----------------
package Tbean.test;
public interface AppConstants {
public static final String driverClass = "driverClass";
public static final String connection = "connection";
public static final String conError = "conError";
public static final String paramBase = "paramBase";
public static final String userId = "userId";
public static final String password = "password";
public static final String selectType = "selectType";
}
--------------- DebugWriter.java---------------
package Tbean.test;
import java.io.*;
import java.util.Date;
public class DebugWriter {
public void writeDebug(String s) {
writeDebug(s,debugFile);
}
public void writeDebug(String s,String sFile) {
FileOutputStream fos = null;
try {
//test for the existence of the file
File f = new File(sFile);
if (!f.exists()) {
fos = new FileOutputStream(f);
} else {
//we want to append to the end of the file
fos = new FileOutputStream(sFile,true);
}
s += "\n";
//pre-pend a date time string
fos.write((new Date(System.currentTimeMillis()).toString() +
":" + s).getBytes());
} catch (Exception ex) {
System.out.println("Error writing debug log in writeDebug : "+ex);
} finally {
try {
fos.close();
} catch (Exception ex) {}
}
}
public void setDebugFileName(String s) {
debugFile = s;
}
private String debugFile = "errors.log";
}
---------------ConnectionManager.java-----------------
package Tbean.test;
import java.io.*;
import java.util.*;
import java.beans.*;

/** The debug boolean - default is false */
private boolean debug = false;
protected Connection con;
protected String driver;
protected String passwd;
protected String url;
protected String user;
protected DebugWriter writer;
PropertyChangeSupport pcs ;
public ConnectionManager () {
