Main-Class manifest in max.jar


Apr 19 2007 | 9:58 am

Hi,
I’m trying to compile through javac a java file adding the libraries NetUtil.jar, max.jar and a personal jar package.
A simple ant buildfile does the work, but when trying to compile with javac it gives the error:
"Failed to load Main-Class manifest attribute from
.. max.jar"

the directory contains:
myClass.java max.jar NetUtil.jar myPackage.jar

the command line compile instructions I give are:
javac -classpath .max.jar;.NetUtil.jar;.myPackage.jar myClass.java

I attach the rar of the directory.

Thanks for helping
Tom

Hi tommaso,

(In case anyone else wants to unpack rar files in OS X:
http://unrarx.sourceforge.net/)

> the directory contains:
> myClass.java max.jar NetUtil.jar myPackage.jar

Here’s what I see:

CMMax.class NetUtil.jar cm.jar
CMMax.java build.xml max.jar

This doesn’t match the command you told us about. Can you please send
exactly the command you are trying to compile with?

Thanks,
Ben

I’m getting the following error messages when trying to send email

I just downloaded and installed the most recent jars (javamail-1.4
and jaf-1.1).

A quick bit of Googling throws up this:

It might be a contender…
