On-Premise Domino Data Access from XPages on Bluemix

Hybrid XPages appplication on Bluemix

XPages on Bluemix has been released as GA on May,2016, and developers can get the environment to develop XPages application easily on the cloud.

XPages code are compiled by "XPages runtime" for XPages on Bluemix. xpages_runtime

This "XPages runtime" is just for runtime environment and should not store any data like Notes Document. Therefore XPages developer usually bind the service called "XPages No SQL Database" as the data store.

In fact, this "XPages No SQL Database" is just NSF file and you can store the data and create the view, form, etc.
However this "XPages No SQL Database" service is part of "Bluemix Labs Catalog" so far and according to IBM Japan, this service should not been used as the production environment.

By this blog post, I tried to use on-premise Domino as the data store for XPages on Bluemix.

Of cause it does not need to be on-premise domino, for example domino on SoftLayer is same meaning. This approach just try to access to outside of bluemix as the data store. It seams to be called as Hybrid XPages Application on bluemix.

 

BluemixのXPagesSet up the domino server to be used from runtime

icon-website-support-200x20To run Hybrid XPages application, you need to configure your on-premise domino.

If you've already used "XPages No SQL Database" service, you maybe can ealiry imagine this, "/O=Bluemix" is used as Organization on bluemix. so xpages on bluemix cannot access to the on-premise domino without cross-certificate.

So as the first step, you need to create the new server id and then, when you deploy the application to the XPages runtime container of bluemix, you also attach the server id so that XPages on bluemix can communicate the on-premise servers through uploaded server id information.

Premise

  • Installed Domino Designer, Administrator
  • Installed Domino Designer 9.0.1FP6 or OpenNTF.org XPages Extension Library verson 15 or above
  • Bluemix settings are configured by Domino Designer preference
  • Already created XPages runtime application on Bluemix, and downloaded nsf and manifest file on your local

*Sorry, the screenshot are all in Japanese. I hope you still can understand where and what I explain.

Step 1: Create Server ID for Bluemix

  1. Launch Domino Administrator, then click "Configuration" tab
  2. From Tools pane, click "Registration" -> "Server".
  3. In the dialog, specify cert id and click [OK]bluemix_server_01
  4. Enter password for Cert ID[OK]
    bluemix_server_02
  5. If you don't need to change, then just Click Continue.
  6. Enter server information for bluemix. Click [Register All] to complete the process.
    bluemix_server_03Server password is optional and usually you might not put password for server. but I added password since I give this server id to the bluemix. Also I recommend to output the server id as file by checking the checkbox.

OK, nothing special, just server id has been registered. the Different thing is you don't need to install domino server by this server id since you only have to pass this server id to the bluemix Xpages runtime.

*Warning 1: Please confirm the server name is contained in "LocalDomainServers" group.

*Warning 2: Please confirm the server which has the access from Bluemix XPages runtime should contains the LocalDomainServers or created server name in Trusted servers field under the server document -> "Security" tab.

Step2: Configure IBM Bluemix Manifest

  1. Open Domino Designer and then open Xpages application NSF which is created from Bluemix and downloaded.
  2. Open "Application property" -> "IBM Bluemix Manifest"
  3. On the right-top corner, Click Edit button in "Hybrid Configuration" section.
    bluemix-domino-server-05
  4. Enter Hybrid configuration
    bluemix-domino-server-06

    • Remote Server Address ( APP_REMOTE_DATA_SERVER_ADDRESS)
      : on-premise Domino IP addressのIP.
    • Remote Server Name (APP_REMOTE_DATA_SERVER_NAME)
      : on-premise Domino server name(i.e. App01/ZetaDataBank)。
    • Runtime Server Name (APP_RUNTIME_SERVER_NAME)
      : Server name created above(i.e. bluemix/ZetaDataBank)。
    • Runtime Server ID File (APP_RUNTIME_SERVER_IDFILE)
      : Server id file created above
    • Runtime Server ID Password (APP_RUNTIME_SERVER_PASSWORD)
      : Server id password if you specified.
    • Directory Assistance Enabled (APP_DA_ENABLED)
      : Specify directory assistance enabled or not
    • Directory Assistance Domain (APP_DA_DOMAIN)
      : domain name(i.e. ZetaDataBank)。
    • Directory Assistance Address Book (APP_DA_ADDRESS_BOOK)
      : Directory NSF which is necessary for authentication of hybrid environment (i.e. “names.nsf”)。

That's all.

I created one sample xpage below:

I specified on-premise domino view in this sample. (Line 5)

Deploy to the bluemix through Domino designer.

bluemix_server_07

Bluemix service is going to reboot automatically. After wait for a while, access to the Xpage URL you created, and then if you get the on-premise data in the view, Success!


How to invoke function from string by XPages SSJS

What's the case you want to invoke the function from string?

There are many situations you want to invoke the function from string of function name. One of case is for example, you might want to switch the functions from the parameter value of HTML Get/Post method.

The example below is client-side javascript(CSJS) when it's triggered from the URL like "http://mydomain.com/ApplyFuncXAgent.xsp?func=callMe". Then switch the flow by the query parameter value of "func".

If you want to simplify the code above, you can write the code like below:

In this case, window object is used to retrieve the function object, then call the target function. However Server-side Javascript(SSJS) does not have the window object like CSJS. Therefore you need to tweak this code a little.

(1) Use "this" instead of "window"

(2) Use eval()

Both (1),(2) can get the same result.

To pass the parameters, Use call() or apply()

Now we could call the function from string of function name. Then if you want to pass the parameters as well when call the funcion, you can use call() or apply() functions. Actually this way is pretty same as CSJS.

For example, when I call the HTTP Get request like "http://mydomain.com/ApplyFuncXAgent.xsp?func=callMe&args=aa,bb". (I added [args=aa,bb] as the function argument's values.) , the SSJS code becomes like below:

The code above is the example of using call(). If you want to use apply(), then instead of passing the arguments separated by comma, pass the Array to the second argument of apply(). Below is the sample code:

Sample code of using XAgent

In my situation, I needed to get the JSON data from the many notes views as the asynchronous connection. (Passing the JSON data for Kendo UI Grid data.) So I decided to use the XAgent to return the JSON data, however I didn't want to create XAgent XPages as many as notes views. So the sample code below calls the function from the Get parameter value of function name and returns the JSON data by the specified function.
HTTP request is like this -> "http://mydomain.com/hoge.nsf/ApplyFuncXAgent.xsp?func=testFunc&args=aa,bb"

Below is the sample code of xpCommon.jss which contains the callFuncByString() above.

The advantage of this logic is avoiding to create many XAgent for notes views. But please remember that dynamically calling the functions from string value sometimes lose the serviceability of code. For example debugging purpose.
*This XAgent is just for example and for the real coding, please pay attention to the security when you use this concept since any SSJS standard functions can be called remotely if you don't add any restriction and it is very dangerous.
