Turgay,

If you use Tomcat 4.0 (servlet spec 2.3), you can just wirte:

request.setCharacterEncoding("ISO-8895-9");
System.out.println(request.getParameter("filename"));

If you use Tomcat 3.2 (Servlet spec 2.2),

String data = request.getParameter("filename");
byte[] raw = data.getBytes("ISO-8859-1");
System.out.println(new String(raw, "ISO-8859-9"));

hope this helps,
Peiqiang Han

David,

For tomcat 3.2 (tomcat 4.0 is different), the classes from $TOMCAT_HOME/webapps/WEBAPP_A/WEB-INF/lib and $TOMCAT_HOME/webapps/WEBAPP_A/WEB-INF/classes sont loaded by a custome classloader. The classes from system CLASSPATH sont loaded by the system classloader. The class loading is in the following order: 1) BootStrap; 2)Extension; 3) System Classpath; 4) special directories known by the custom classloader, so

1) the classes in $TOMCAT_HOME/webapps/WEBAPP_A/WEB-INF/lib
and in $TOMCAT_HOME/webapps/WEBAPP_B/WEB-INF/lib sont completly different.

2) The classes in the system CLASSPATH take precedence.

Regards

-Peiqiang
