These are not paths - they're just disconnected strings. They should point to the directories where you installed this software, java sdk and j2ee sdk respectively

 so I have set the "JAVA_HOME" as : "j2sdk1.4.2_04" and "J2EE_HOME" as: "j2sdkee1.3".

But now I got :
C:\>j2ee -verbose
ERROR: Set JAVA_Home to a path of a valid jdk.
-------------------------------------
Can anyone please tell me what I have done wrong ? Thanks !

meow......
 

Is j2sdk1.4.2_04 properly installed? Why do you have j2sdk1.4.2_03? I would uninstall/remove the latter unless you have a very good reason for its being there oryou could get problems

err ..... I installed it(j2sdk1.4.2_03) a month ago ... I don't mean to leave it there....but but .... I don't know how to uninstall it ? please help !!! thanks !

Add/Remove programs

JAVA_HOME =C:\j2sdk1.4.2_04
J2EE_HOME =C:\j2sdkee1.3

If you type:java -version at the dos prompt it will tell you which is the default JVM

It'll tell you the version of java.exe that appears first in the path variable

Since she apparently doesn't have a java.exe in the path, it has to look in the registry, in which case the default version will be reported.

Hi Experts,

    After I removed j2sdk1.4.2_03, the j2ee command seems to be recognized. However, I still have errors while I try to start the j2ee server. THe following is the error message. Could anyone
please give me some helps ?

Another service is already running on, probably, port 8080. Make sure that no other web services are running.

err .... I didn't start any service by myself, unless some service is started automatically ..... How do I know if I have other web services running or not ? Thanks !

Start menu->Control Panel->Administrative Tools->Services

Look for:
Apache Tomcat

With status: Started

You can also run the command 'netstat' in a command prompt window, and look for port 8080

Hi,

   Thanks for the information. I first went to "Start menu->Control Panel->
   Administrative Tools->Services". But I couldn't find "Apache Tomcat" ?!

   Also, I tried netstat, but I don't see port 8080  ? Please help, what should I do or check next ???
Thanks very much !!!

The ports in use by J2EE RI are:

Try to open a web browser window to the following addresses (just click on them):
http://localhost:8000
http://localhost:8080
http://localhost:8090

The console probably won't look into the registry for java.exe - it certainly doesn't on my machine

This is the answer you accepted with some speed to your last question:

>>You can use any J2SE 1.3.1 and above. I would recommend 1.4.2,.

The warning message you received above suggests a quite different picture:

>>
C:\>j2ee -verbose
Warning: This J2EE SDK release is designed to run on J2SE 1.3
>>

Hi experts,

    Thanks for all the information ! I tried the localhost: 8000, 8080, 8090:

when I tried : http://localhost:8000/ , it automatically becomes https://localhost:8443/
when I tried : http://localhost:8080/ and http://localhost:8090/, I got "The page can not be  
   displayed".

Also .... if "Warning: This J2EE SDK release is designed to run on J2SE 1.3" is true, how do I get J2SE1.3 ? I only see J2SE1.4.2 and J2SE1.5beta on the website .........

    I am stuck and confused ! Please please help !!! many many thanks !

meow.

Also, I don't know why the Java icon (of J2SE1.4.2) showed up in the start bar ? while the server didn't start up successfully .... I don't know how to terminate the program either :-(
 

>> Also .... if "Warning: This J2EE SDK release is designed to run on J2SE 1.3" is true, how do I get J2SE1.3 ?
J2SE 1.3 is a minimum requirement, meaning that J2EE 1.3.1 will not run on anything earlier. You're fine with 1.4.2. I run the J2EE stack using 1.4.2!

The error you're getting is similar to one I got once. Please post the setting of J2EE_HOME! Plus, whenever you change a system environment variable, you have to open a new command window to get those changes!

Here are the variables :

JAVA_HOME : C:\j2sdk1.4.2_04
J2EE_HOME: C:\j2sdkee1.3
-----------------------------------------------------
what does it mean by "whenever you change a system environment variable, you have to open a new command window to get those changes" ?
What should I type in the command window to get the changes ?

many many thanks !!!

Thanks experts,

I still have the same errors after I have a new command window..... I guess I will try to use J2SE 1.3.1 and see what happens ......

Thanks a lot for helping me out !!!

Just restart your computer and try again before you install J2SE 1.3.1!!!
