Re: modules-0.2.jar compile problem

[Peter Pfeiffer]

I believe this reported problem still exists. If I use the solitary  
jar for mediarss, it compiles and runs with JVM 1.4.2.  If I use the  
modules-02 jar, it compiles but when run with JVM 1.4.2, I get the  
noted exception:
>> Exception in thread "main" java.lang.UnsupportedClassVersionError:  
>> com/sun/syndication/feed/module/mediarss/io/RSS20YahooParser  
>> (Unsupported major.minor version 49.0)
>>



There is also a problem when building with xcode. If I want to  
include more than one module, for example, xcode expands all the jars  
and then makes a new jar with all the class files. Unfortunately it  
appears to overwrite the rome.properties file from each jar so that  
the last unjarred props file is used. I tried to just build with a  
separate rome.properties file, but it is also overwritten.

Is there a way to write out the rome.properties to see what module  
properties have been set?

Thanks,

peter
