Sharan Foga updated OFBIZ-4240:
-------------------------------
Sprint: Bug Crush Event - 21/2/2015
> Override UiLabels / Properties through tenant specific database
> ---------------------------------------------------------------
>
> Key: OFBIZ-4240
> URL: https://issues.apache.org/jira/browse/OFBIZ-4240
> Project: OFBiz
> Issue Type: Improvement
> Components: framework
> Affects Versions: Trunk
> Reporter: PR
> Priority: Minor
> Labels: properties
>
> UtilProperties being in base gets complied and loaded first ahead of both
> entity and service modules. So, as such the service and entity classes won't
> be available there directly. Now the attempt is to have a embedded service
> call within the UtilProperties.getBundle(.....) method right after the lines
> below
> Properties newProps = getProperties(resource, candidateLocale);
> if (UtilValidate.isNotEmpty(newProps)) {
> // The last bundle we found becomes the
> parent of the new bundle
> The idea is that by default a set of properties would be loaded from the
> UiLabels.xml files. However, right after we should be able to call a service
> to override any labels (in newProps) passing the newProps as an argument.
> So far, so good ?
> Next the problem... How to configure a service call? Find the below usage in
> base module
> ClassLoader loader = Thread.currentThread().getContextClassLoader();
> Iterator<Init> cachedClassLoaders = ServiceLoader.load(Init.class,
> loader).iterator();
> while (cachedClassLoaders.hasNext()) {
> Init cachedClassLoader = cachedClassLoaders.next();
> try {
> cachedClassLoader.loadClasses(loader);
> } catch (Exception e) {
> Debug.logError(e, "Could not pre-initialize dynamically
> loaded class: ", module);
> }
> }
> So, can we write a class say UtilTenantProperties under webtools and load
> that dynamically? This class can then be used to load the appropriate
> delegator to query properties to override and return an updated newProps and
> rest continues as before? The reason thinking of webtools is to eventually
> use the webtools label manager to manage and update the override fields into
> the database.
> Also perhaps we would need UtilTenantProperties or better still
> UtilPropertiesOverride (to make it useful even in single tenant cases) as
> interface under base module and then have the implementation under webtools
> linked to META-INF/services file entry.
