Question

I am a C# Developer, and I recently acquired a project at work that is Java.

The Project is to modify an existing Java application, which I have done and was simple. However, I can not for the life of me get it to run from the command line.

I am receiving the error

Exception in thread "main" java.lang.NullPointerException
         at com.dhl.sop.label.LabelReportHandler.main(LabelReportHandler.java:63)

There is no code at line 63 in that file. I have altered the file dramatically just to see that line number change, and it hasn’t. I am really not sure what else to do, I have googled a bit and I have come up empty handed. Any information and/or suggestions are greatly appreciated.

Thank you!

generateSOPLabel.cmd

EDIT: The command the cmd script is running

java com.dhl.sop.label.LabelReportHandler

Ok, it’s working just fine for me after fixing the ant build script to build the files and pointing the startscript to the correct output files.

Your problem is probably that Netbeans are building the files to the BUILD folder and the script is looking in CLASSES.

Changes in startscript:

export CLASSFILE_PATH=$SOPLabel/build/
 ..
java  -classpath $CLASSPATH com.dhl.sop.label.LabelReportHandler

Added to build.xml:

 <target name="compile" 
        description="compile the source ">    
    <javac srcdir="src" destdir="build"
             classpathref="classpath"/>   </target>

Built with: ant compile and then enter code here./generateSOPLabel.sh outputs:

Usage : java LabelReportHandler
