Hi,

WinXPprofSp1, JSK 1.4.2_03, Eclipse 2.1.2, MyEclipseIDE 2.7 RC2, Tomcat 5.0.18.

Simple JSP, put breakpoint into it:
<%
String s = “hiho”;
int i = 7;

log(s + ” ” + i); // <== put breakpoint here.
%>
Debugger stops at the breakpoint, but the variable “i” is not shown into the local variables list!

I reconstructed the code from memory, becaue my ME trial expired today and I can’t try it out again.

Thanks in advance,
Victor

Victor,

One of the things that can cause this is the compiler optimizing your variable out of existence. In the code snippet you supplied, since ‘i’ is initialized and never changed most compilers will simply replace it with the constant its been initialized to in order to improve performance.

Scott,

you were absolutely right.
