logging the stacktrace

logging the stacktrace with log4j:

import org.apache.log4j.Logger;

import org.apache.log4j.PropertyConfigurator;

// ......

static Logger logger = Logger.getLogger(MyClass.class);

// ......

public static void debugException(Exception ex) {

    //ex.printStackTrace();

    logger.error("An error occurred in MyClass.", ex);

}

frames in Latex

in order to print text inside a frame:

 \centering
    \fbox{
    \begin{minipage}{1.0\linewidth}

    The text that will be printed in frame goes here..

    \end{minipage}
    }

proguard ant task

proguard (http://proguard.sourceforge.net/) promises for  the following:

• Creating more compact code, for smaller code archives, faster transfer across networks, faster loading, and smaller memory footprints.
• Making programs and libraries harder to reverse-engineer.
• Listing dead code, so it can be removed from the source code.
• Retargeting and preverifying existing class files for Java 6, to take full advantage of Java 6's faster class loading.
