RE: application.getRealPath(/) from ActionForm???
I have never used a Singleton before.
My understanding is that it is just a static class memeber.
There will be only one person trying to load this form at a time since it is
for management purposes only.
Maybe I am going about this all the wrong way.
Here is what I am doing.
When the xml file is changed the client then runs the application that
creates many jsp/struts files in xml syntax.
All forms are blank to start with except the ManagerForm.
In order to have this populated I do the following:
jsp:useBean id=bean
class=com.supernovasoftware.exploreco.struts.ManagerForm/
This loads the form object and populates the bean because I am calling the
load method from the constuctor.
bean:write name=bean property=stringIndexed[0]/
Initally this uses the values from the xml file, but once submitted values
are handled by ManagerForm.
This is necessary so that when data is invalid it is filled in with the
changes the client made until it
is correct.

My guess about the null control serverlet, is because struts may not
init
the form's control servlet after the form constructor completes.
If you can take a look at my answer to Setting external JNDI
properties,
you can put your file in classpath and load it.
BTW, you might have a performance problem loading the file for every
constructor of your action object. You might want to load your file at
startup and access it thru a singleton.
Good luck.

Is your XML file static? If it does, you cam place the xml file in your
class path and use my other posted solution to have access to its
InputStream.
If you dont like to place it in classpath, you can create a Singleton
wrapper around your XML and load it up during application startup, via
Struts plugin or a servlet.

This file is and xml file that contain that data that the form needs to be
filled with. It is in my WEB-INF/data folder. The problem is that I
cannot
find a way to tell my form where to load this data from. I need need to
access to the ServletContext so I can get the real path of the web
application. Some has to know how to do this easily.

My guess about the null control serverlet, is because struts may not init
the form's control servlet after the form constructor completes.
If you can take a look at my answer to Setting external JNDI
properties,
you can put your file in classpath and load it.
BTW, you might have a performance problem loading the file for every
constructor of your action object. You might want to load your file at
startup and access it thru a singleton.
Good luck.

ActionServlet as = this.getServlet();
This is returning null. What is the proper way to get a reference to
the
controller servlet from and Action from?

Actually I am calling a funtion that loads values into the form in the
object. This load method needs to find a relative path. I cannot seem
to
get a reference to the controller servlet or any other way to get the
path
to my WEB-INF.
public final class ManagerForm extends ActionForm {
public ManagerForm() throws Exception {
this.load();
}
...
...
}

If you deploy your app as a WAR file, then it is the correct result
since
there is no real directory to return
But you can use this code
InputStream is =
servlet.getServletContext().getResourceAsStream(pathName);
where pathName is the context path to your file in the WAR archive. (ie
/WEB-INF/yourFileName.txt)
Good luck.

Subject: application.getRealPath(/) from ActionForm???
When deploying my Struts application I ran in to a small problem.
I had hard coded the path to an xml file used to load values into my
form.
I need to get a relative path. I tried the following, but got a null
pointer.
ActionServlet as = this.getServlet();
ServletContext application =
as.getServletConfig().getServletContext();
String basePath = application.getRealPath(/);
Thanks for your time,

Have you given a thought on my Singleton solution?

It is not static. I need it to load when ActionForm is loaded. Is there
no
way to load form values from an external source?
