2006/5/30, Patrick Middleton <[EMAIL PROTECTED]>:
The JVM on the target machine has encountered a classfile in JDK 1.5 format. This most likely means you built using the JDK 1.5 compiler, which became the default after a recent software update, and the machine on which you are trying to deploy is still using the 1.4.2 JRE. Since WebObjects has not (yet?) been qualified for Java 5, you are best off rebuilding using JDK 1.4*, see also http:// docs.info.apple.com/article.html?artnum=75505 , as per Cliff Tuel's email "Re: Java 1.5 & WO?' of Tue, 25 Apr 2006 16:07:21 -0700 (PDT).
Hi Patrick Unfortunately setting 'Target VM Version' to 1.4, as an article suggests, doesn't always help. Recently I've encountered the following issue with BigDecimals. The problem was that in the project that I joined several months ago many BigDecimals were initialized like this: "new BigDecimal(10)" - on 1.4 compiler BigDecimal(double) was invoked (a number was implicitly casted to double) and everything was OK. But after compiling on 1.5, BigDecimal(int) was invoked (since this constructor has been added in Java 1.5). And after deployment we've seen NoSuchMethod exceptions. Eventually the easiest thing was to downgrade to 1.4. (http://www.macosxhints.com/article.php?story=20060121171126988). I only wonder how many such issues exist.
