%description
Apache JServ is a servlet engine, developed by the Java Apache Project
<http://java.apache.org/>. The Apache JServ servlet engine is written
in 100pc Java application, and listens for servlet requests using the
Apache Java protocol (AJp). Typically, these requests will originate
from the mod_jserv Apache module (DSO included). This package contains
a LGPL'ed implementation of sun's java servlet api version 2.0 by Paul
Siegmann <http://www.euronet.nl/~pauls/java/servlet/>

%description -l pl
Apache JServ jest silnikiem serwletowym, rozwijanym przez Java Apache Project
<http://java.apache.org/>. Silnik serwletowy Apache JServ został napisany
od początku do końca w Javie; nasłuchuje wywołań serwletu wykorzystując
protokół Apache Java (AJp). Zazwyczaj wywołania te pochodzą z modułu
Apache mod_jservmodule (łącznie z DSO). Pakiet ten zawiera sunowską
implementację api serletów w javie w wersji 2.0 (na licencji LGPL)
