i have defined a dev.properties file for the mule flow.where i am passing the username and password required to run the flow.This password gets updated everymonth.So everymonth i have to deploy the code to the server after changing the password.Is there a way , where we can keep the properties file outside the code in mule server path.and change it when required in order to avoid redeployment.
One more idea is to completely discard any usage of a file to pickup the username and password.
Instead try using a credentials providing service, like a http requestor which is collecting the username and password from an independent API(child API/providing service).
Store it in a cache object-store of your parent API (the calling API). Keep using those values, unless the flow using them fails or if the client needs to expire them after a month. Later simply refresh them.
You can trigger your credentials providing service using a scheduler with a Cron expression having Monthly Triggers.
No, because even if the properties file is outside the application, properties are loaded on application deployment. So you would need to restart the application anyway to pick up the new values.
Instead you can create a custom module that read the properties from somewhere (a file, some service, etc), assign the value to a variable, and use the variable instead at execution time. Note that some configurations may only be set at deployment time, so variables will not be evaluated as such.
If the credentials are not exposing your application security or data, then you can move them to another config file(place it Outside mule app path). Generate a RAML file which will read & reload the credentials after application deploy/start-up, and store them in cache with timeToLive around 12 hours.
The next time when you have to change Username/Password, change in the file directly and cache will refresh it automatically after expiry time.
Actually not because all the properties secure properties needs to be there at runtime and is it is not there your application will get failed,
There is one way but it’s not best one, instead of editing code you can directly edit secure property I.e username and password in your case directly in cloudhub runtime manager properties tab.
After editing just apply changes then api will restart automatically and will deploy successfully

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 am in the middle of working with, and getting a handle on Vuejs. I would like to code my app in a way that it has some configurable behaviors, so that I could play with parameter values, like you do when you edit your Sublime preferences, but without having to compile my app again. Ideally, I would want a situation where I could have my colleagues be able to fiddle with settings all day long, by editing a file over FTP maybe, or over some interface....
The only way I know how to do it now, is to place those settings in a separate file, but as the app runs in the client, that file would have to be fetched via another HTTP request, meaning it's a publicly readable file. Even though there isn't any sensitive information in such a configuration file, I still feel a little wonky about having it public like that, if it can be avoided in any way...
Can it be avoided?
I dont think you can avoid this. One way or another your config file will be loaded into the vuejs application, therefore being visible to the end user (with some effort).
Even putting the file outside of the public folder wouldnt help you much, because then it is unavailable for HTTP to request the file. It would only be available to your compile process in this case.
So a possible solution could be to have some sort of HTTP request that requests GET example.com/settings and returns you a JSON object. Then you could have your app make a cookie like config_key = H47DXHJK12 (or better a UUID https://en.wikipedia.org/wiki/Universally_unique_identifier) which would be the access key for a specific config object.
Your application must then request GET example.com/settings (which should send the config_key cookie), and your config object for this secret key will be returned. If the user clears his cookies, a new request will return an empty config.
I want to store values in variables to access form another page (a.k.a State management).
Now I cannot use sessions since I have multiple Zope instances & if one fails the user need to be redirected to another Zope instance and one session is valid only for one Zope instance.
Now my remaining options are
submit a Hidden input tag using POST method
Passing through URL with GET method
Using cookies
Using Database (which I think is 'making simple things complex'.)
I am not even considering the first 2 methods and I think using cookies is not secure.
So is there a commercial or open source module that can securely (encryption etc.) do cookie management.
If not I will have to use a database.
Please inform me, if I am missing something.
Version - Zope 2.11.1
The SESSION support built-in to Zope 2 actually keeps the session in a temporary partition of the ZODB so I think it actually is valid for multiple Zope clients connecting to the same ZEO server. The cost of this is that all session changes invoke the transaction machinery and result in a commit, so just make sure you're not using the SESSION in something very low-level like PAS auth or you'll have commits hitting your ZODB for every image, CSS file, and JS file.
If you edit a service in Windows 7 and go to the Log On Tab, there is an option to "Allow service to interact with desktop". I'm trying to ensure that it is set for a certain service using VB.NET. Does anyone know of a way to do this?
Note: Doing this during the install of a program is not an option. It has to be done at run time.
Call ChangeServiceConfig with SERVICE_INTERACTIVE_PROCESS. The benefit of using Windows API is that it should takes care of the notification and consurrency part and invalidate the cache in other programs that uses service controller, and when something goes wrong, you get an error code back. Generally speaking you should not access the registry if you can use API to get/set a setting.
Service configuration is stored in the registry, under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\
With a key for each service.
It appears that the third to last flag within the Type value corresponds to the 'interact with desktop' value.
For example, a service set to NOT interact with the desktop has a value of:
Type REG_DWORD 0x0000010 (16)
whereas that same service, when set to be allowed to interact with the desktop has a value of:
Type REG_DWORD 0x0000110 (272)
I can't say that this is guaranteed as I've not done any testing, but it may be a good place to start. You'd need to restart the service before the changes to this value take effect.
I am looking for a method of storing Application Messages, such as
"You have logged in successfully"
"An error has occurred, please call the helpdesk on x100"
"You do not have the authority to reset all system passwords" etc
So that "when" the users decide they don't like the wording of messages I don't have to change the source code, recompile then redeploy - instead I just change the message store.
I really like the way that I can easily access strings in the web.config using keys and values.
ConfigurationManager.AppSettings("LOGINSUCCESS");
However as I could have a large number of application messages I didn't want to use the web.config directly. I was going to add a 2nd web config file and use that but of course you can only have one per virtual directory.
Does anyone have any suggestions on how to do this without writing much custom code?
In your Web.config, under appSettings, change it to:
<appSettings file="StringKeys.config">
Then, create your StringKeys.config file and have all your keys in it.
You can still use the AppSettings area in the main web.config for any real application related keys.
Put the strings in an xml file and use a filewatcher to check for updates to the file
Put the strings in a database, cache them and set a reasonable expiration policy
You can use ResourceManager class. See "ResourceManager and ASP.NET" article at http://msdn.microsoft.com/en-us/library/aa309419(VS.71).aspx
