Why is there no java.lang.Number?

[dua3...@gmail.com]

Hi,

I have an existing codebase that I'd like to use in my cn1 project. But I get compilation errors when using java.lang.Number. I found out that it's missing from cn1's library and cannot imagine any reason why it's not there. java.lang.Float and java.lang.Double inherit from java.lang.number in JDK 5. Why did cn1 chose to do differently?

Sorry, it seems java.lang.Number is not CLDC, just as is java.lang.math. I leave the question here in case anybody else might be looking for this.

We support most Java 5 features actually but adding java.lang.Number was a bit painful. You can check out the source code of our retro weaver work in SVN and see if there is a way to add java.lang.Number, I would personally love to have it.

bam - here is the next wall I hit! After removing all dependencies to reflection, I get now the error of missing java_lang_Number.h in the iOS build.

BTW. it is frustrating, that the build spits out only one error. I don't know ,whether I should try to fix this error as well - what will be the next thing that is missing or not working. Why is it not possible to check the code before sending it to the build system, if there are dependencies, which can't be fulfilled.

If you compile your java against the ckdc1.0 .jar. Instead of the standard jdk javac will identify all these errors for you.

another thanks - I will try this too. Another stupid question then . why does the CN1 template use the standard jdk ? - or is it me, that I have overlooked something in the docs ?

We do. The path isn't something we can completely control in IDE's so the build.xml script compiles the code with our authorized classpath.
I guess you hacked our build.xml and commented that stuff out.
