Matlab 6.5.1 not working with Java 1.5.0
|
|
|
| I am using matlab code, which calls java object Obsid to make some
calculations, like this:
o = Obsid('obsid.ini');
....
value = o.evaluate(nData(1), nData(2), nData(3));
This all worked fine, when I had Java version 1.4.1, but now after
updating to Java 1.5.0 it doesnt work anymore.
Matlab says only: "??? Undefined function or variable 'Obsid'.",
although freshly compiled .class files exist in the same folder as is
the matlab code, and this folder is also set in matlabs path and
system classpath.
Anyhow I can call basic java classes without problems, example below
works fine:
m = java.lang.String('foo');
What might be the problem with my system?

A few questions:
(1) When you say that you "updated to Java 1.5," what do you mean? That you
installed Java 1.5 on your machine, and are using it to compile your code?
Or something else?
(2) What do you get in MATLAB when you run[color=darkred]
(3) What OS are you running MATLAB on?

I installed java 1.5 and compiled my code using that version.

Matlab says: >> version -java
ans =
Java 1.3.1_01 with Sun Microsystems Inc. Java HotSpot(TM) Client VM
(mixed mode)
[color=darkred]

Windows XP
So obviously my Matlab is running different version of Java, and
these two are not incompatible. Can Matlab Java be somehow updated?

| Hi Tim,
I think I found a solution that should help you. I found it by going to The
MathWorks support site and searching for "java version":

Good luck!
