Lorenzo Bernacchioni updated WW-4410:
-------------------------------------
Affects Version/s: 2.3.16.3
> Custom configuration providers accessing servlet-context
> --------------------------------------------------------
>
> Key: WW-4410
> URL: https://issues.apache.org/jira/browse/WW-4410
> Project: Struts 2
> Issue Type: Improvement
> Components: Dispatch Filter
> Affects Versions: 2.3.16.3
> Reporter: Lorenzo Bernacchioni
> Priority: Minor
>
> 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 in the Dispatcher class 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}
