Can't configure Jboss 4.0.x in eclipse after installing Jbos

[jboss2win]

Hi,guys!
I installed Jboss IDE 1.4.0, and wanted to configure Jboss 4.0.x in eclipse 3.1.2, but the follewing problem occurred:

Error 2006-05-07 09:20:07.831 Problems occurred when invoking code from plug-in: "org.eclipse.jface".
java.lang.NoSuchMethodError: org.eclipse.jdt.internal.debug.ui.launcher.LauncherMessages.getString(Ljava/lang/String;)Ljava/lang/String; at org.jboss.ide.eclipse.launcher.ui.configuration.ServerLaunchArgumentsTab.createControl(ServerLaunchArgumentsTab.java:86)......

is this something wrong with the version of eclipse, which is not suitable for Jboss IDE?

Thanks in advance!

Your Eclipse version requires JBossIDE 1.5 not 1.4..
