suggestion for html

[Jackie Wang]

I am thinking of writing some classes for printing out the text report.
Different reports will contain different column number, and different alignment and length.
So I think I should write a generic one as a "template" as interface? or parents class?
Can anyone have some suggestion? Thanks!

The report will be like:

Person Goods Percent
A 130 9.23%
B 2 20.00%
C 5 2.55%

So I think i will create a html file with table so that it will be align well, any beter suggestion?

A good open source solution might be the Velocity template engine project. Here is an introductory article at JavaWorld:
http://www.javaworld.com/javaworld/jw-12-2001/jw-1228-velocity.html
Summary
The Velocity Template Engine lets you render data from within applications and servlets. Primarily used to develop dynamic, servlet-based Websites, Velocity's clean separation of template and Java code makes it ideal for Model 2-style Model-View-Controller (MVC) Web development. As a general template engine, Velocity suits many other purposes, such as code generation, XML generation and transformation, and textual stream processing. This article introduces the Velocity Template Language (VTL) and provides examples of how to use the Velocity engine, including how to generate Web content in a Java servlet environment.

thanks julia for the quick response.
But I am wondering whether there's an easier approach becoz my report is really really simple.
Any suggestion? I really appreciated it.

any one can help me? I have already included that vm file in the same directory.

In your Java code you need to specify where the Velocity engine should look for ".vm" files.

Properties props = new Properties();
props.put("file.resource.loader.path", templateBaseDir);
VelocityEngine ve = new VelocityEngine();
ve.init(props);

Hope it helps.
