Hi,

I am using Mac OS X 10.5.6 and XCode 3.0.

Well, Java programs are not completely portable. Certain
things have to be programmed differently for the MAC,
such as the About and Quit menu have to be in a different
place and the Command key has to be used instead of
the Control key.

Yes, I think my XCode project is built by Ant. I am not
using JNI libraries.

I am presently not using bouncycastle or any external .jar
files, so I don't know why it is complaining about
bouncycastle.

Here is a copy of my Info.plist file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" " http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Which version of Mac OS X?  Xcode?

Is your Xcode project built by Ant?  Does it have a build.xml file?

In general, you don't need to recompile Java source to run it on the 
Mac.  Jar-files are already cross-platform.  You can just copy the 
jar file(s) and put them in an app-bundle with a suitable Info.plist, 
icon-file, etc.  An exception to this is if you use JNI libraries, 
which do need to be compiled for Mac OS X.


When I try to run the ...app, I get the message that the main class 
is not specified, etc.

The message you posted suggests that the Info.plist is incorrect.  
Please post the XML contents of your Info.plist.


When I try to run the ...jar, I do not get the message that the 
main class is not specified, but I do get the message that there is 
no Manifest section for bouncycastle, etc.

This suggests that your Manifest does not specify the signatures for 
one or more bouncycastle classes.


Why do I need org/bouncycastle/asn1/DEREnumerated.class, and how 
would I have to specify it in Manifest?

Are you directly using or referencing any bouncycastle classes?  If 
so, exactly how are you including these classes in your build?  That 
is, are you merging the bouncycastle jar into another jar, copying a 
jar-file into the app-bundle, or something else.

If you are not using or including any bouncycastle classes, even 
indirectly, then you'll have to tell us what classes or jars you are 
including.
