Queer problem with Robocode in XP Professional

Hi everyone, I'm new to robocode.
I have a desktop with XP Professional, and when I downloaded robocode
and installed it everything went fine. There seems to be nothing wrong with it at all, except that the menus like FILE, ROBOT, and others don't work! If I click them a blank white square comes out. Could anyone help me? I tried reinstalling, but that didn't work either.

Thanks in advance, Josh

This could be due to a problem with your Java installation and/or setup.
You must make sure that you have a JDK (Java Developer Kit) or JRE (Java Runtime Environment) version 5.0 or 6 installed. If not, download and install it from http:

http://java.sun.com/javase/downloads/index.jsp

If you already have a JRE or JDK installed (the JDK contains the Java compiler and other stuff), you need to set up the JAVA_HOME and PATH user environment variables properly. You setup environment variables from your Control Panel -> System -> Advanced System Settings -> Environment Variables.

The JAVA_HOME is used by Java to locate the path to every tool and library that is needed by Java. Hence this path must be setup for Java to work properly. The JAVA_HOME must be set up to something like:

JAVA_HOME
C:\Program Files\Java\jdk1.5.0_21

You should look in C:\Program Files\Java or C:\Program Files (x86)\Java to see the specific name and version.

Now, you also need to setup your PATH. PATH is used by almost any operating system to locate the commands for your command prompt (Windows) or shell (Linux/Unix/Mac OS X etc.). Hence, you need to add the path to the `bin' folder inside the JAVA_HOME (which you have already set up to C:\Program Files\Java.). This is needed so your system will be able to locate the `java' tool and `javac' if you have installed the JDK and not just the JRE.

If you don't have a PATH in your environment variables, you just create it, and set it to:

%JAVA_HOME%\bin

Windows will interpret %JAVA_HOME% to the path you set for JAVA_HOME, which is the C:\Program Files\Java\jdk1.5.0_21 (depending on your specific version and also where you installed the JDK or JRE).

If you already have a PATH, then you insert this before anything else already written in the PATH:

%JAVA_HOME%\bin;

Notice the semicolon, which is used to separate this path will the other paths you already have in the PATH variable.

When this is setup, and you have pressed "OK" on the window where you specify your environment variables, you should test it by opening a command prompt (press the Windows key and R in the same time, and Windows will prompt you with a text field where you can enter a command). In this field you enter cmd.exe and press Enter. In the command prompt, you should try to write:

java

If your JAVA_HOME and PATH is setup correctly, some information will be written out by the java tool. Otherwise the command prompt will tell you that it could not find the command.

If you have installed the JDK (not JRE), you can also try to write:

javac

Which will also write out some information about the javac tool, or give an error.

I hope this fixes your problem.

I tried your suggestion, but nothing changed...
The toolbar menu items still come out as blank rectangles...
Thank you anyway for your suggestion.

Any suspicious output on the console? Sometimes the JavaVM gives you
hints on what's going on... (and robocode itself gives some general
debug output, too)

Oh- one more thing. After leaving Robocode running for a while,
I went back to it and all the menu entries were perfectly visible... I tried starting it up again and the blank squares were back.

This is very strange. I have never heard of anybody else having this problem. Is there anybody else on this forum that has experienced the same problem? If so, what did you do to solve it?

Josh, have you tried to run another Java application on your system? You could e.g. try out some of the sample applications that comes with the JDK or download a Java application with a GUI from the Internet and see if you got the same problems as with Robocode.

Thanks in advance,

Other programs work just fine, like demos in the JDK subfolders or something big, like Eclipse IDE, which is written in Java.

Any other suggestions, perhaps?

Thanks,

It is like finding the needle in the haystack. I am guessing that the
problem is caused by the lightweight vs heavy AWT/Swing components.
Hence, I have made a new version of Robocode (Alpha version) where I
tell AWT/Swing as early as possible that lightweight components must be
disabled - meaning that heavy components will be used instead.
I hope this fixes the issue. Try downloading and installing this new
version with my fix:
robocode-1.7.2.0-Alpha-setup.jar
<http://robocode.sf.net/files/robocode-1.7.2.0-Alpha-setup.jar>
Please tell me if this fixes the problem for you? :-)

I tried downloading and installing it, but the problem does not go away. I've got Java 6 update 18 (same with the JDK).
Thanks anyhow.

I saw the bug report. Perhaps it would be a good idea to upload a screenshot, but I cannot modify your bug report. Should I upload a new bug report?

If you try to upload the screenshot as anonymous, you will probably not be allowed to upload the screenshot, as anybody would be able to upload pictures. So you might need to register yourself as a SF user in order to do it.

If you send the screenshot to me at fnl(at)users.sourceforge.net, I will upload the screenshot for you.
