I want to automatically detect and install subapplications, instead of
hand editing the web.xml file. (It's hard to "patch" with ant).
So I wrote a plugin, that looks up instances with getResourcePaths() and
installs them with initApplicationConfig().
But this method is protected. I can probably make a custom build to
avoid this, but I'm interested to know why is it protected? Is there a
better way to programmatically initialize sub applications?
public class SubAppConfig implements PlugIn {
static Category cat = Category.getInstance(SubAppConfig.class.getName());
/**
* The debugging detail level for this plugin.
*/
private int debug = 0;
public int getDebug() {
return (this.debug);
}
public void setDebug(int debug) {
this.debug = debug;
}
/**
* The parent directory where we look for sub-application
configurations.
*/
private String pathname = "/WEB-INF";
public String getPathname() {
return (this.pathname);
}
public void setPathname(String pathname) {
this.pathname = pathname;
}
public void destroy() { }
public synchronized void init(ApplicationConfig config) throws
ServletException {
ActionServlet servlet = config.getServlet();
try {
Set resourcePaths =
servlet.getServletContext().getResourcePaths(pathname);
Iterator it = resourcePaths.iterator();
while (it.hasNext()) {
String path = (String) it.next();
if (path.indexOf("-struts-config.xml") != -1) {
String prefix =
path.substring(path.indexOf("-struts-config.xml"));
cat.debug("found prefix: " + prefix + ", path: " +
path);
servlet.initApplicationConfig(prefix, path); //hmm,
protected...
}
}
} catch (Exception e) {
servlet.log("Error while configuring sub applications; ", e);
throw new UnavailableException("Unable to configure sub
applications.");
}
}
}
