Pretty URL in jira plugins with Java

[Miraculous Ladybug]

hey, does someone know how to create url-patterns in java for a jira plugin with dynamic data?

such as

<servlet name="overview"

class="jzt" key="overview">

<url-pattern>/plugin/{name}</url-pattern>

</servlet>

how to pass the {name} parameter? where do I get it from? in the servlet class? If so, how exactly?? Using pretty URLs in a JIRA plugin (atlassian.com) <- this link doesn't explain what to do in java to pass the parameters correctly
