Class PJARedirectServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          com.eteks.awt.servlet.PJAServlet
              com.eteks.awt.servlet.PJARedirectServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

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 :

• In the init parameter named com.eteks.awt.servlet.destinationservlet
• In the parameter named com.eteks.servlet.destinationservlet sent in user request.

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
