For example, in the previous template page, you want to change title, keywords and description dynamically.
Add the following code to the java class on the template page:


@Parameter(defaultPrefix = BindingConstans.LITERAL,name = "title",requred=true)// I'm going to set it as the argument here \ 
@Property(write=false)// Annotate unwritable properties  
private String title;

Finally, when used:


<div t:type=" template " xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd" title=" Write your parameters here "> 
XXX 
</div>

After rearranging the server, it has been found that normal title properties can be displayed...
