cannot find main class

Jahn, Ray (R.)
Dear IJ development team:

I need to run IJ with JRE 1.3.1-11 on some machines due to requirement of other applications.  For JRE 1.3.1-11, IJ 1.38 or 1.39 have problems in loading, whereas IJ 1.37 loads OK.  Can someone advise where my mistake is?

Thanks.

Test of the initial loading of IJ

IJ   JRE
1.37 1.3.1-11 OK
1.37 1.4.2-07 OK
1.37 1.6.0-05 OK
1.37 1.7.0-22 OK
1.37 1.7.0-23 OK
1.38 1.3.1-11 cannot find main class
1.38 1.4.2-07 OK
1.38 1.6.0-05 OK
1.38 1.7.0-22 OK
1.38 1.7.0-23 OK
1.39 1.3.1-11 cannot find main class
1.39 1.4.2-07 OK
1.39 1.6.0-05 OK

JRE 1.7.0-23 is obtained from

download.java.net/jdk7/binaries

version: MS Windows, the JAR version, not the EXE version

IJ MS shortcut specifications:

target = "c:\programs\java\jre 1.7.0-23\bin\javaw.exe" -mx80m -cp ij.jar ij.ImageJ
start-in = "c:\programs\nih ij 1.39"

Re: cannot find main class

Wayne Rasband
I found this in the release notes
(http://rsb.info.nih.gov/ij/notes.html):

v1.38a, 27 October 2006
     ImageJ 1.38a requires Java 1.4.2 or later due to the addition
     of mouse wheel and maximize/minimize support.
