Lorenzo Bernacchioni updated WW-4410:
-------------------------------------
Description:
I'm using custom configuration providers following the suggestion of [this
post|http://cppoon.wordpress.com/2013/11/11/change-apache-struts2-configuration-programmatically/comment-page-1/#comment-157].
I figured out that my custom configuration provider needed access to the
servlet-context so I patched the code to let, in case the constructor is
available, instantiate a ConfigurationProvider with the servlet-context as
argument
{code}
private void init_CustomConfigurationProviders() {
String configProvs = initParams.get("configProviders");
if (configProvs != null) {
String[] classes = configProvs.split("\\s*[,]\\s*");
for (String cname : classes) {
try {
Class cls = ClassLoaderUtil.loadClass(cname,
this.getClass());
ConfigurationProvider prov;
try {
Constructor constructor =
cls.getConstructor(ServletContext.class);
prov =
(ConfigurationProvider)constructor.newInstance(servletContext);
} catch (Exception e) {
prov =
(ConfigurationProvider)cls.newInstance();
}
configurationManager.addContainerProvider(prov);
} catch (InstantiationException e) {
throw new ConfigurationException("Unable to
instantiate provider: "+cname, e);
} catch (IllegalAccessException e) {
throw new ConfigurationException("Unable to
access provider: "+cname, e);
} catch (ClassNotFoundException e) {
throw new ConfigurationException("Unable to
locate provider class: "+cname, e);
}
}
}
}
{code}
