Eclipse for Linux - Java Issues [message #144464]

Hello, I recently installed Fedora Core 4, which came with an Eclipse
package (v3.2?). When I attempted to write Java code in the IDE, however,
I get errors for ArrayList<Character>. It tells me that ArrayList is not
generic. However, I get no such problem when doing the same thing in
Eclipse v3.1 for Windows. I tried changing the JDK Compliance level
between 5.0 and 1.4, but neither worked. Any idea of what the problem
might be?

Fedora Core 4 comes with the GCJ and Eclipse 3.1. GCJ doesn't support
Java 1.4 as far as I know. I've installed the Sun JDK from JPackage.org
to use the new Java 5.0 language features in FC4.

Kind regards,
Daniel

Daniel,

I also have the Sun JDK installed, but I'm not sure how to tell Eclipse to
use that instead of what it uses by default? Could you tell me what you
changed to make it work?

You can launch Eclipse with the -vm /path/to/sun's/java command line
argument, or you can make sure Sun's java shows up first in your PATH.

Hope this helps,

The JPackage.org RPM does this by adding a new entry for the Sun JDK to
the alternate system and making it the default (this changes the
symlinks java, javac, and rmic). So Eclipse will be started using the
new JDK. For programming with Java 1.5 you must change the used JDK in
Eclipse under Window -> Preferences -> Java -> Installed JRE. The
directory is the GCJ installation dir. This must be changed to the Sun
JDK installation dir.

I cannot look at a running Sun JDK and Eclipse installation because I've
updated to FC5 and my wlan card doesn't work :-(.

HTH
Daniel

Thanks, Daniel and Jeff. I went to Windows->Preferences->Java->JRE and
searched for other JREs, found the Sun one and made that the default.
Everything compiled and ran. :)
