Want to compile class in a different folder

Posted: Oct 17, 2002 8:27 AM

I have classes in this directory structure:
C:\portalbean\portal

All classes in this folder are package as so:

package portal;
class PortalTest implements PortalReadWrite
{
...
}

I have tested the application on the command prompt as so:
C:\portalbean>java portal.PortalTest

This Works.
My problem is that I now want to move the PortalTest.java file to a folder called TestDrivers. This is because I want to have PortalTest2.java ...PortalTestN.java

So thus now PortalTest2.java is in a folder called:
C:\portalbean\portal\TestDrivers

import portal.*; //note this is the only line I have changed
class PortalTest2 implements PortalReadWrite
{
...
}

However the class does not compile. Gives errors such as:

C:\portalbean\portal>cd TestDrivers

C:\portalbean\portal\TestDrivers>javac *.java
PortalTest1.java:1: package portal does not exist
import portal.*;
^
PortalTest1.java:17: cannot resolve symbol
symbol : class PortalReadWrite
location: class PortalFtpTest
class PortalTest1 implements PortalReadWrite
^
PortalTest1.java:19: cannot resolve symbol
symbol : class PortalFtp
location: class PortalTest1
PortalFtp ftp;
^
PortalTest1.java:25: cannot resolve symbol
symbol : class PortalFtp
location: class PortalTest1
ftp = new PortalFtp();
^

Please help,

try this,
javac -?
take a look at the -d

D:\projects\viaportal\feeds\war>javac -?
-? is an invalid option or argument.
Usage: javac <options> <source files>

where <options> includes:
-g Generate all debugging info
-g:none Generate no debugging info
-g:{lines,vars,source} Generate only some debugging info
-O Optimize; may hinder debugging or enlarge class files
-nowarn Generate no warnings
-verbose Output messages about what the compiler is doing
-deprecation Output source locations where deprecated APIs are used
-classpath <path> Specify where to find user class files
-sourcepath <path> Specify where to find input source files
-bootclasspath <path> Override location of bootstrap class files
-extdirs <dirs> Override location of installed extensions
-d <directory> Specify where to place generated class files
-encoding <encoding> Specify character encoding used by source files
-target <release> Generate class files for specific VM version
