Same problems here. I used some classes/methods from CLDC 1.1 without
knowing, and some floating point too, but the Motorola test device only
had CLDC 1.0. Eclipse/MTJ was set up to CLDC 1.0 but the errors remained
undiscoverd. That was the cause of most other problems I described in my
earlier postings. How did I find that out? I ported the project to
NetBeans, which found the errors right away. Nuff' said.

I tried many SDKs, different versions (Sun, Motorola, Sony Ericsson,...)
with all the same effect. No error message related to the CLDC 1.0
setting, the jar just didn't run on the real device. That made me so
angry that I deleted everything that sounded like eclipse and switched
to Netbeans. To answer your question I downloaded and installed it
again. BTW, it's still the same with the latest version of Pulsar (Helios).
The setting CLDC 1.0 was done in the 'Application Descriptor'. Try it,
insert the following code, but do something with the variable, otherwise
the line will be optimized away. 'sum' and 'cnt' are of the type int, too.
int z = (int)(15.0 - ((double) sum / (double) cnt));
It will compile with no errors, no warnings. But when you download the
..jar to a CLDC 1.0 phone, like my Motorola V3, it will crash.

You're welcome. With Netbeans I also had to change this code
InputStream isLeft =
Object.class.getResourceAsStream("/arrow_left.png");
InputStream isRight =
Object.class.getResourceAsStream("/arrow_right.png");
try {
arrowLeft = Image.createImage(isLeft);
arrowRight = Image.createImage(isRight);
} catch (Exception e) {
// Do Something();
}
to this one to get rid of error messages. When CLDC was set to 1.1 the
version above compiled too, but not with 1.0. With MTJ it compiled in
both cases.
try {
Class c = Class.forName("java.lang.Object");
InputStream isLeft = c.getResourceAsStream("/arrow_left.png");
InputStream isRight = c.getResourceAsStream("/arrow_right.png");
arrowLeft = Image.createImage(isLeft);
arrowRight = Image.createImage(isRight);
} catch (ClassNotFoundException cnf) {
// Do Something();
} catch (Exception ex) {
// DoSomething();
}
