public class PJARedirectServlet
extends PJAServlet

This servlet uses PJAServlet services to get a default toolkit, and redirects all servlet calls to a destination servlet ensuring to it to have a default toolkit at disposal for graphics servlet. The destination servlet class can be coded in either ways :

For example, if you wanted to call a servlet with the URL http://server/servlet/com.eteks.servlet.DefaultToolkitTest?param1=value1¶m2=value2 you have to change by http://server/servlet/com.eteks.awt.servlet.PJARedirectServlet?destinationServletClass=com.eteks.servlet.DefaultToolkitTest¶m1=value1¶m2=value2 Or if you servlet initialization file contained something like : 
servlet.toolkit.code=com.eteks.servlet.DefaultToolkitTest
 servlet.toolkit.initArgs=initParam1=value1, initParam2=value2
It will become : 
servlet.toolkit.code=com.eteks.awt.servlet.PJARedirectServlet
 servlet.toolkit.initArgs=initParam1=value1, initParam2=value2, destinationServletClass=com.eteks.servlet.DefaultToolkitTest, toolkitFontsPath=pathWithPJAForTTFFonts
