2 add in Web. xml
<Servlet>
<Servlet-Name> tohtm </servlet-Name>
<Servlet-class> com. jetsum. mystatic. tohtml </servlet-class>
</Servlet>

<Servlet-mapping>
<Servlet-Name> tohtm </servlet-Name>
<URL-pattern>/web/tohtm </url-pattern>
</Servlet-mapping>

Easy to use mytest. jsp (under wwwroot)
<A href = "Web/tohtm? URLs =/kszx. jsp "> Generate a static page </a> kszx. jsp: the dynamic page for generating htm
If it is not under wwwroot, it must be written under wwwroot/PP.
<A href = "../web/tohtm? URLs =/kszx. jsp "> generate static pages </a>
