it is a little bit ugly to do that in Velocity, here is the way I do it
....
//TODO: these stuff need to be injected
VelocityEngine ve = new VelocityEngine();
try {
Properties p = new Properties();
p.setProperty("resource.loader", "string");
p
.setProperty("string.resource.loader.class",
"org.apache.velocity.runtime.resource.loader.StringResourceLoader");
ve.init(p);
StringResourceRepository vsRepository = StringResourceLoader
.getRepository();
String myTemplateName = "maglink";
String myTemplateBody = "Hi $name ! How do you do?" ;
vsRepository.putStringResource(myTemplateName, myTemplateBody);
} catch (Exception e) {
e.printStackTrace();
}
VelocityContext context = new VelocityContext();
context.put( "name" , "Youssef");
Template template = null;
try {
template = ve.getTemplate("maglink");
StringWriter sw = new StringWriter();
template.merge(context, sw);
assert sw.toString().equals("Hi Youssef ! How do you do?") ;
} catch (ResourceNotFoundException rnfe) {
// couldn't find the template
} catch (ParseErrorException pee) {
// syntax error: problem parsing the template
} catch (MethodInvocationException mie) {
// something invoked in the template
// threw an exception
} catch (Exception e) {
}
// TODO Auto-generated method stub
Regards, Youssef
