[xmlvm-users] Help! Trying to compile some JDBC code from Android to iPhone.

[Shekar M. <sh...@mo...>]

Hi All,

I am trying to cross-compile some JDBC code (developed for Android) to 
an iPhone target. I get a compilation error (in XCODE) for XMLVM 
generated code constructs such as:

    _r22.d = [((java_sql_ResultSet*) _r0.o) getDouble___int:_r31.i];

I looked at the compat-lib for objc and the declaration for 
java_sql_ResultSet interface (in file java_sql_ResultSet.h) has no 
method definitions in it. So, I don't know why a construct such as:

     _r22.l = [((java_sql_ResultSet*) _r0.o) getLong___int:_r31.i];

seems to compile properly.

Would someone know where the full definition for java_sql_ResultSet is, 
so I can add an implementation for getDouble___int method?

Thanks,
Shekar

On a similar note, I wonder how I can add and contribute support for 
java.text package (or for that matter any missing classes that I need) 
for Android development?

Thanks.

You can add functionality in xmlvm/src/android2iphone. Once you have
something working, please upload a diff to our review system (details
at XMLVM.org/contribute)

Objective-C is a dynamically typed language. Even if methods are
missing, the compiler will only issue a warning at best. You will only
notice problems at runtime.

Arno,

Thanks for your reply. I am getting a compile error on the 
"getDouble___int" method invocation. The error says:

"Incompatible types in assignment"

I am not an Objective-C expert but I wonder if a method is missing (or 
if a signature is not found), the compiler assumes a return value of 
"int" and thus raises the aforementioned error. So, it appears that I 
will have to fill in details in java_sql_ResultSet.[hm] with appropriate 
signatures and implementation. Please confirm.
