Class FileViewerServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

nl.nn.adapterframework.http.HttpServletBase

nl.nn.adapterframework.webcontrol.FileViewerServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig, DynamicRegistration, DynamicRegistration.Servlet

@IbisInitializer
public class FileViewerServlet
extends HttpServletBase

Shows a textfile either as HTML or as Text.
This is a servlet because in JSP you cannot give the content-type depending on a condition.

Parameters:

• fileName: the filename to retrieve
• returnType: either HTML or TEXT

When the resultType is HTML, the FileViewerServlet.signal properties are looked up from the AppConstants and additional styling is done.

        FileViewerServlet.signal=ERROR WARN
        FileViewerServlet.signal.ERROR.pre=<font color=red>
        FileViewerServlet.signal.ERROR.post=</font>
        FileViewerServlet.signal.WARN.pre=<font color=blue>
        FileViewerServlet.signal.WARN.post=</font>
        etc.
        FileViewerServlet.signal.css=IE4.css
        

The last item specifies which stylesheet to use.
