Hi,
I am new to GeoTools. I need to render point features in a JMapPane
with each point represented by a dot with some adjacent text (the value
of a feature attribute). I can render the dots using:

Greg,
I too struggled with this when I first started messing with GT. Once I
switched from trying to code Styles and Symbolizers directly in my Java
code to using SLD, it became much easier. Below is an example of a Rule
that contains a TextSymbolizer that I am actively using right now. The
label is actually being placed on a polygon shape, but I think it may
still be a useful example. Have a look at the SLD class.
<Rule>
<TextSymbolizer>
<Label>
<ogc:PropertyName>COUNTYNAME</ogc:PropertyName>
</Label>
<LabelPlacement>
<PointPlacement>
<AnchorPoint>
<AnchorPointX>0.5</AnchorPointX>
<AnchorPointY>0.5</AnchorPointY>
</AnchorPoint>
<Displacement>
<DisplacementX>0</DisplacementX>
<DisplacementY>0</DisplacementY>
</Displacement>
</PointPlacement>
</LabelPlacement>
<Font>
<CssParameter name="font-family">SansSerif</CssParameter>
<CssParameter name="font-style">bold</CssParameter>
<CssParameter name="font-size">8</CssParameter>
</Font>
<Fill>
<CssParameter name="fill">#000000</CssParameter>
</Fill>
</TextSymbolizer>
</Rule>
