Creating custom scheduled jobs

I am looking to fill in a couple gaps in my knowledge how to create a custom scheduled job that will appear in WVS Job Scheduler Administration.   I have been using the Windchill Customizer's Guide 9.1 for the initial set of steps.

I see I have to add some entries to the wvs.properties.xconf file as shown below  from the guide.

Add the following to your wvs.properties.xconf file (edit as needed):

<Property default="MyCustomJob" name="myJob.description"/>

<Property default="ext.wvs.CustomJobs" name=" myJob.class"/>

<Property default="myCustomJob" name=" myJob.method"/>

<Property default="true" name=" myJob.enableOnContainers"/>

<Property default="myJob" name="schedulejobs<N>"/>

I have to create the java class (myJob.java) and then compile it to create the myJob.class.

I have two areas I am having difficulties getting through succesfully.

1. How to correctly create the SearchCondition in the java class.  Below is an exerpt from the Customizer's Guide.  What I want to search for are all representations that were created in a date range.  For example, I want to republish all representations (thumbnails) that were created between 2013-06-01 and 2013-09-01 and in a specific context and folder.  I am not sure what the correct syntax.

qs.appendWhere(new SearchCondition(WTDocument.class,

Iterated.LATEST_ITERATION,

SearchCondition.IS_TRUE),

******

  2.  actually compiling the myJob.java file.  I included the import statements as shown below.  I receive a lot of errors when I try to use 'javac' to compile the myJob.java routine.  As I write this, I am wondering if my path variable is not set correctly to compile the routine cleanly.    Any hints are greatly appreciated.
