I know that local.Properties overrides project.Properties.
I also know that that these files define… database connections, ports, build environment, frontend HTTPS, etc.
I further know that project.Properties contains more properties.
Will appreciate if Hybris experts tell me syntax of local.Properties, illustrating with some example.
Please provide correct info.
If we talk about the syntaxes of entries in the project.properties file, then it is key=value
The property files in the hybris are of two types:
The extension level - The property file project.properties is the configuration file that carries properties in the key-value pair for the configurations involved on the extension level For instance, Consider a property in the project.properties of the yacceleratorstorefront (storefront template) extension storefront.storelocator.pageSize.Desktop=10 which clearly indicates the 'StoreLocator' results page size configuration per store. Since the store locator functionality is specific to the storefront and has no relevance for the other modules (like core, facades etc), the property is kept at the extension level.
Please note, project.properties reside in the extension folder
The global level - This is the property file which is the global configuration file, and deals with the properties are extension agnostic and carry a global impact. For instance the property commerceservices.default.desktop.ui.experience=responsive sets the ui experience to responsive mode that specifies the deployment to be for the responsive format.
The local.property file supersedes all of the properties with the same key that is defined in any of the project.proprties.
Please note, the local.properties file reside in the hybris/config folder
The hybris registry creates a property configuration map which constitutes all of the properties mentioned in the deployment configuration. The same could be managed in the HAC under platform/configuration.
The clear intent of the local.proprties file is to have information which either requires to be overriden on a global level. The override may be of different types, e.g. cart expiry time could be made different on different environments by the use of the local.property files.

property call hierarchy (from primary to secondary):
java -Dproperty.key=something
hybris/config/local.properties
hybris/*/(extension-name)/project.properties
hybris/bin/platform/project.properties
and within java code:
configService.getString("property.key", "last fallback value, if no propertyfile provide this key");
You could review all current variables using the hac interface for properties: http://localhost:9001/platform/config

Currently I read properties file by defining a global element like;
> <configuration-properties doc:name="Local Configuration Properties"
> doc:id="899a4f41-f036-4262-8cf2-3b0062dbd740"
> file="config\local_app.properties" />
But this is not enough for me
when try to deal different clients dynamically.
Usecase
I need to pick right configuration file when request comes in. That is, for different clients I have different properties file.( their credentials and all different). When request is received from listener, i'll check with clientid header and based on that value, i'll pick right configuration file. My properties files are added to different location.(Doing deployment through openshift.) Not within mule app. So, we don't need to redeploy the application each time, when our application supports new client.
So, in this case, how to define ? and how to pick right properties file?
eg:
clientid =google, i have properties file defined for google-app.properties.
clientid=yahoo, i have properties file defined for yahoo-app.properties.
clientid=? I'll add properties file ?-app.properties later
Properties files are read deployment time. That means that if you change the values, you to redeploy the application to read the new ones. System properties need a restart of the Mule Runtime instance to be set. And Runtime Manager properties need a restart of the application. In any case the application will restart. Properties can not be used as you want.
There is no way to use configuration properties dynamically like that. What you could do is to create a module using Mule SDK that read properties files and returns the resulting set of properties, so you can assign the result to a variable, and use the values as variables. You will need to find a way to update the values. Maybe set a flow with a scheduler to read the values with a fixed frequency.
I built a virtual filesystem (not a namespace extension) for Windows which acts as a frontend of our document management server consisting of files and folders. In order to be able to display some metadata of the DMS objects in Windows Explorer as additional selectable columns, I successfully provided properties to the Windows Property System by implementing a COM Property Handler. Wheras normal property handlers focus on specific file types for which they feel responsible, my Property Handler adds properties to all files regardless of their type. Because Property Handlers can only be registered on the file type level, I registered my handler for about 30 types under
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\PropertyHandlers\<.Extension>
However, I did not manage to register the Property Handler for folder objects. Since all objects in our file system are virtual I build the property store (IPropertyStore) by implementing IInitializeWithFile instead of IInitializeWithStream. The properties are requested from our DMS with the path of IInitializeWithFile acting as key and were not read from an objects content. This concept would work for folders as well.
For getting called on folders I tried to associate the handler by registering under different well known identifiers like Folder, Directory, AllFileSystemObjects and * instead of the file extension without success.
I also didn’t find anything in the MSDN documentation regarding this aspect.
Is there a way to register a Windows Property Handler on folders? Or is there some other way to add custom columns to folders in Windows Explorer?
I'm not sure if it is possible to do this.
Property handlers are clearly not the right approach, they are system wide and there can only be one per file extension. They should only be implemented by the software that "owns" the file extension and can parse the file to extract properties.
The old column handlers would have been your best bet (IMHO) but they are officially dead and you already said you can't use them.
Have you considered creating a namespace extension? Either as a root item somewhere (Desktop or My Computer) the way My Documents used to work in 2000/XP or maybe something more along the lines of how OneDrive works?
I'm not sure if desktop.ini files work in the root of a drive but it might be worth looking into. You would then find yourself in the poorly documented land of [.ShellClassInfo] and its CLSID, CLSID2 and UICLSID members. The general idea would be to act as a IShellFolder proxy on top of the "real" IShellFolder so you could create a multiplex property store. I think there are some (undocumented?) property keys you can override to change the folders default columns and tooltips as well.
There is also something called a delegated folder that allows you to play with nested PIDLs but the documentation is once again pretty useless so I'm not sure if this is something worth looking into.
A 3rd option is to pretend to be a cloud storage provider. I don't know if this gets you any closer to your goal and you would still have to implement some NSE bits to get to the point where you can layer yourself on top of the underlying IShellFolder. This feature is rather new and only documented to work on Windows 10.
The inner workings of how Explorer/IShellBrowser is connected to the IShellFolder/IShellView is one of the least documented parts of Windows. There are hundreds of undocumented interfaces. Explorer gives DefView special treatment leaving other 3rd-party implementations out in the cold.
My feeling is that there is no clean solution to implement this on top of a drive letter but you might get lucky, if Raymond Chen drops by he might have some tips for you...
I have a mule application comprising of 10 mule XML files. Some of these XML files need to use same property from commong prperties (config.properties) file.
(1) Should ALL the flows that need use a given property load the properties file containing that property using --
<context:property-placeholder location="config.properties" />
(2) OR should only one of the XML file add property-placeholder?
(3) If option (2) is right, then does the order of mentioning the xml files as config.resources in mule-deploy.properties play any role?
Please shed some light on this.
You only need it once, and it does not matter where you put it.
You only need one property file and you can setup this for 3 environments liks DEV,QA and PROD and setop property to pick right file.
There is a lot of documentation that shows users different ways to read a properties file in Mule flows.
Here are three approaches on how you can do this:
Reading a properties file using ${Key} expression
Reading a properties file using ![p[‘Key’]] expression
Reading a properties file using p() function from DataWeave
If you deploy multiple applications through a Shared Resources structure, don’t set anything in the properties files, as there might potentially be conflicts between the various apps that share a domain. Instead, set environment variables over the scope of the deployed app, its domain, and other apps under that domain.
As explained in Shared Resources, in Studio you can create these variables through the Environment tab of the Run Configurations menu, reachable via the drop-down menu next to the Play button.
I want to do custom configuration parameters in config.yml
Example:
In config.yml file
security_enhancement:
authentication:true
authorization:true
In same format like swiftmailer configuration etc.I'm not getting idea how to define.
I'm getting error like:
1/2 ParseException: Unable to parse in "\/var\/www\/demo\/app\/config\/config.yml" at line 217 (near "authentication:true").
Am I missing something here? Is it necessary to add in depending injection extension file? .Actually I want to enable disable authentication,authorization execution during dev mode which is implemented in listener which can be done using config_dev.yml . I don't want to add under Parameters. Any suggestions?
As you've rightly theorised, you do indeed need to add in DI extension files, assuming your configuration relates to particular bundles (which it almost certain will).
Whilst parameters can simply be defined at will, configuration features hierarchical structure and validation.
Usually, configuration is used to in turn, define parameters, but it allows for the values to be parsed and validated prior to their instantiation, so that bundle writers can provide better guidance as to how their services can be used (with meaningful errors), and trust the values that are being passed into them.
A decent read on how to get started with config component can be found in the Symfony2 docs: defining and processing configuration files with the config component.
I need to update the JSF2.0 (Primefaces) tooltips dynamically without server restart.
Meaning need to find a way where tooltips (atm from properties file) of the a running application can be changed without requiring a server restart.
We are running websphere and deploying a non exploded EAR (can probably convince to deploy exploded war)
Any Ideas or tips please. Thanks you
The value attribute of the p:toolTip component must be an EL expression or a literal text. Usually, one would reference a resource bundle declared using the var attribute of the f:loadBundle tag, in the EL expression for the tooltip.
The underlying resource bundle declared using the basename attribute could be backed by a property file itself (in which case you need to place the property file in the appropriate directory on the classpath), or for that matter it could be a custom ResourceBundle implementation that could read from a properties file (located outside the container), or a database or any store for that matter.
You could therefore change your existing EL expression from the existing one defined as:
<f:loadBundle var="msg" basename="propfile_location" />
to
<f:loadBundle var="msg" basename="fully qualified class name of the ResourceBundle class" />
In simpler words, you will need to roll your own ResourceBundle class(es) to support the various locales. Needless to state, but you will need to override the ResourceBundle.getObject(java.lang.String) method, as it is invoked by the ResourceBundleELResolver implementation when evaluating the EL expressions referencing ResourceBundles.
Additionally, you will need to ensure that the ResourceBundle.getObject(java.lang.String) implementation of your ResourceBundle will always re-fetch and return the value corresponding to the provided key. Failure to ensure this would mean that the initial value fetched by the resource bundle may be returned on subsequent invocations, especially if you are caching the initial value. You are likely to encounter this behavior even if you deploy an exploded WAR file where you can modify the property file contents without a redeployment of the application, and that is why it is important to use a custom ResourceBundle implementation that does not cache values.
