exception.
Code which is being executed:
try {
Velocity.init();
} catch (Exception e1) {
e1.printStackTrace();
}
then
try {
Velocity.evaluate( context, writer, "string",
template.getSzablon());
} catch (ParseErrorException e) {
e.printStackTrace();
} catch (MethodInvocationException e) {
e.printStackTrace();
} catch (ResourceNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
This code does not on production server, but works on development machines. I
have tried using VelocityEngine instetad of Velocity Signleton but no luck.
I also tried initializing Velocity during servlet startup but nothing changed.
Any help appreciated :-)
