When debugging remotely and making a code change I get: Hot code replace failed: Scheme change not implemented. Based on what I have read this appears to be a problem with the compiler byte code compatibility. There was a write up ( http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3938568 ) - but that did not seem to work. JDK (only one) 1.4.2_13 JBoss 4.0.4 AS - web application running out of development root Eclipse 3.2 with JBoss IDE plugins - using eclipse to build, not ant explicitly. Any suggestions for this configuration TIA View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999919#...
