Sure, here it is:
1. this snippet you have to add to your stuts-config.xml
<plug-in
className="com.mycompany.myproduct.servlet.InitPlugin"></plug-in>
2. this is the plugin-code:
public class InitPlugin implements org.apache.struts.action.PlugIn {
public void destroy() {
try {
HibernateUtil.destroySessionFactory();
} catch (Exception e) {
log.error(e.getMessage());
e.printStackTrace();
}
}
public void init(ActionServlet arg0, ModuleConfig arg1) throws
ServletException {
try {
HibernateUtil.initSessionFactory();
Locale locale = Locale.getDefault();
DateLocaleConverter converter = new DateLocaleConverter(
locale, FormatUtils.getDatePattern(), false);
converter.setLenient(true);
ConvertUtils.register(converter, Date.class);
ImagesManager.setImagesStoragePath(arg0);
} catch (Exception e) {
log.error(e.getMessage());
e.printStackTrace();
}
}
}

Thanks. Could you show me how to write such plug-in?

I think there are 2 cases:
1. you need a param that is available to the Servlet
and is not uniquie
to any particular Action
for eample in my application users can uppload
images, so after the
upload I store them in a subfolder in the
application. here is how I do it:
a. this snippet I add in web.xml in
<servlet> tag
<init-param>
<param-name>imagesstorage</param-name>
<param-value>store_images</param-value>
</init-param>
b. here is the code to get the param
in one of the
actions (in fact I do this in one plugin because
this path is constant
all the time, so I read it only on startup)
StringBuilder path = new
StringBuilder();
path.append(servlet.getServletConfig().getServletContext().getRealPath("/"));
path.append(servlet.getServletConfig().getInitParameter("imagesstorage"));
2. every separate Action needs some initial
parameter.
In this case why do you need to put as an init
param? it's enough
just to have static field in the Action class ...
I hope this is usefull for you.

For traditional servlets, you can set init
parameters
in the web.xml and read it in a static init method
in
servlet class. Can I have similar things for
action?
If I need some of these init parameter for my web
app,
what is the best way to do it with struts?
