Hi, as the bytecode didn't change from 1.3 to 1.5, I would assume that I could prepare some .class files<br />
by 5 and run them somewhere on 1.3 or 1.4 (IF ONLY NOT USING API INTRUDUCED SINCE).<br />
<br />
When I target an older version in javac I seem to produce other format of .class files? Is the above assumption wrong then?<br />
<br />
Before you advise me so: it's no longer possible to compile those sources on 1.3 as you start to write generics.<br />
<br />
Any experience with this kind of problems?<br />
<br />
Note: many customers demand 1.3 because of product restrictions (BEA) or compliancy (J2EE).<br />

Deploying JAVA 5.0, targeting 1.4 or 1.3

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
