PS. in case it's easier, here is a skeletal example of how you might
do things...
// in your main class, after code for creating map context and
adding layer(s)
MyFrame frame = new MyFrame("My beautiful map");
frame.setMap(mapContext);
SwingUtilities.invokeLater(
Hi Luong,
I suspect the problem is in your frame class. What sort of object are
you using to display the rendered map ? E.g. a JMapPane ?
If it's not too long, post the code for that class and let's see what
we can see.

Hi,
That was exactly what i was trying to do, attempting to pass the return
value from the function createStyle method into the mapcontext. Sorry for
the confusion, it makes a little more sense now. What i did in my
ConstructMap.java code was created a style variable, and color c variable
and
Hi Luong,
I don't quite understand what you're trying to do, but passing an
instance of your ConstructStyle class to the map context or whatever
won't work because it is NOT a Style object. What you want to pass it
is the return value of the createStyle method.
If you want a separate style helpe
Hi,
i added some slight modifications to my app, in particular to adding the
createStyle func and cleaning my main file. When running the app, i keep

com.mycompany.Map_AppV2.ConstructStyle cannot be cast to
I will try it i'll let u know how it goes.
Thanks again.

Hi,
thanks for the reply, i added the section to my ConstructStyle.java class
file, but wanted to ask because i want to display my shapefile by using
java's file chooser (i.e file->open->my.shp), is there anything that i would
need to also add with regards to the function createLineStyle?

Hi Luong,
There's some confusion about what's what in your code - especially
regarding interfaces. The good news is that it can all be a lot
simpler :)
For starters, to make a simple style for a line feature type you can
just use a method like this...
public Style createLineStyle(String fea
Hi,
i did some adjustments to my code, in particular i declared a
stylefactory object within my ConstructStyle.java and in the constructor i
added it by doing:
this.lineStyle = styleFactory.createStyle();
to help create the style with the addition of doing declaring an instance
