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
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
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.

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);
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
getting the following error:
Exception in thread main java.lang.ClassCastException:

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?
The
The reason i ask is beacuse very early on when following some of the
tutorials in my ConstructMap.java i created a constrStyle object passed the
following:
// Pass file and feature schema referrence to myCreateStyle function
constrStyle.myCreateStyle(file, myFeatureTypeSchema);
There
I will try it i'll let u know how it goes.
Thanks again.

Hi,
i'm using the tutorials to help me build my gis app to essentially diplay
my shapfile which is done by selecting the file name via java's file menu

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
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
