MobileFirst and Worklight with Java 8 - ibm-mobilefirst

How to use Java 8 for MobileFirst / Worklight mobile applications? I have always encountered articles that it wouldn't work with Java 8. Any one had luck in using it with Java 8?

At this time, MobileFirst does not support Java8. We're actively working on this and we should be able to announce support "soon". Be aware that there are several different aspects to your issue -
Developer environment; CLI and Studio, and embedded Liberty server
MobileFirst Server, of many different flavors; Liberty, WAS, Tomcat, etc.
Suggest you ask your question again in a week or so, and I should be able to provide a more specific answer.

Mobile first Server 8 queries

I new new Mobile first platform and websphere application server(WAS)
I installed mobile first server (MobileFirst-8.0.0.0)on my system and I am assuming the mobile first runs on WAS
I am having following queries.
How to deploy .war file in mobile first server 8 as it's console which is run 9080 port doesn't have option to deploy war file as it only have option to deploy adapter ?
If a deploy adapter on the mobile first server, at what location on the server i find the file ?
If war deployed on websphere then still how i use mobile first sevices like push, analytics.
Can i use spring and hibernate while developing adapters or any other ibm options are available in contrast to spring and hibernate.
As I am new to ibm products, want to know what are the topics and product need to learn before i start development.
Kindly share
Before all, you should google.

In v8.0 you no longer need to deploy .war files to the underlying application servers. Certainly not in the developer edition.
You either start a server instance on Bluemix, or use the DevKit for local installations. Then, you either create native apps or Cordova apps - using the native tools or Cordova CLI, and develop adapters using Maven.
Learn more in the Knowledge Center and find additional documentation and tutorials in the developer center.

The adapter file (.adapter) is deployed to the MobileFirst database.

like push, analytics.
Yes, those are services that are available to you out of the box. Learn more in the knowledge center and developer center.

ibm options are available in contrast to spring and hibernate.
Yes, you can use these technologies. And adapter is a JAX-RS application and so you can integrate a

How to develop with WebSphere 8.5 traditional on OS X

Does anyone have any idea how this can be done?
It's my understanding that WebSphere 8.5 traditional is not compatible or will not run on OSX. I am looking for solutions for developers to develop with a WebSphere 8.5 traditional server locally.
Could we setup some servers on a windows machine so they can be used remotely during development?
I downloaded the Eclipse plugin but it gives me the warning saying OS X is not compatible with WebSphere traditional and to give it a remote server address. I tried to point eclipse to a server on a windows PC but it still wants a runtime installation directory.
I found a single thread on WASDev with a similar question talking about runtime stubs with a dead link.
I tried using a liberty server but I get nothing but null pointer exceptions and JMX errors, I don't think this is a valid alternative in my corporate environment.
For developing against WebSphere traditional on OSX, you could try Docker! We've published developer edition versions of 8.5.5.9 and 9.0.0.0, see:
https://developer.ibm.com/wasdev/blog/2016/06/15/websphere-traditional-ibm-http-server-docker-hub/
https://hub.docker.com/r/ibmcom/websphere-traditional/
The Dockerfiles used to produce these images are here, should you want to try building your own instead:
https://github.com/WASdev/ci.docker.websphere-traditional
However, your question is more specific to getting the tools working.
The last I read (and I'll try to confirm/update the answer when I do find it), is that the stubs are part of the full product install for RAD (selectable via Installation Manager).
You're correct that traditional WAS doesn't run on OSX. Remote servers are an option but traditional WAS is considered by some developers to be heavy and slow to restart, so your developers might appreciate something local and more nimble. Liberty is supposed to run on OSX, and things that run on Liberty -usually- will run on traditional, so getting to the bottom of your Liberty problems might be useful. If you haven't already, posting your question on WASDev might reach someone that has a better answer than this one.

Integration of MobileFirst Application onto BlueMix

I have a set of applications that have been developed by IBM using MobileFirst so it uses Worklight servers and adapters within the application.
I have been requested to investigate the possibilities of taking a hybrid mobile application developed on worklight and trying to migrate it onto something like IBM's BlueMix.
I was hoping someone could provide me with some insight as to how much work may be involved or if this task is even possible?
Thanks in advance.
Assuming you are using MobileFirst Platform Foundation 7.1, you can run your MobileFirst Server on IBM Containers, a technology powered by IBM Bluemix... you can read more about it here: https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/7.1/ibm-containers/
You can start by evaluating it: https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/7.1/ibm-containers/evaluate/
And later, assuming you are an IBM MobileFirst Platform customer, migrate your existing project and applications to it: https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/7.1/ibm-containers/run/
You will also want to experiment with MobileFirst Foundation 8.0 beta: https://mobilefirstplatform.ibmcloud.com/beta/
v8.0 beta also provides an all-new approach for running on Bluemix: https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/8.0/ibm-containers/using-mobile-foundation/
Using 8.0 will require some migration effort, but it'll be worth it. :)
You could migrate your adapters and the app integrated with the MFP SDk as is and move it to Bluemix using MFP 7.1 on containers. The effort is minimal - say 2 days. Based on your comments above, If you want to ditch all that and remove worklight out of the equation all altogether, you will have to hand roll all that functionality that worklight was providing to you and of course maintain it yourself. Then this ceases to be a worklight question :) and the effort is certainly more than couple of days.

IBM WAS 8.0 to 8.5.5 migration

I am asked to upgrade IBM WebSphere application server 8.0 to 8.5.5 on linux environment. Could you please give me a step by step guide for this migration?
thanks,
Kumar
The simplest method (assuming your WebSphere instances have enough spare CPU/disk/etc) is to build a second WebSphere cell at the new level and migrate applications across one at a time. Access to the application servers should be controlled by either a web server (using the WAS plugin) or an IP sprayer product and which version of app server used should be controlled in that layer. Updating in place has many pitfalls and can be difficult to recover from if something goes wrong which can lead to extended down time for your applications.

Is it possible to deploy a JAX-RS web service to MobileFirst Server?

My team is working on the migration of a hybrid app from Tibco Silver Mobile(TSM) platform to IBM MobileFirst Platform.
I have a JAX-RS webservice developed using Weblogic IDE which is currently hosted on TSM server. This webservice does a security check for all the incoming back-end requests and pass the request to the back-end if it is from a valid source.
When the app will be migrated from TSM to MobileFirst platform the TSM server will be moved out of the scene. I am looking for some alternate options for hosting this JAX-RS webservice. I don't want to make any changes to the webservice since it is a tested and proven code used in the TSM based solution.
I understand from the IBM MobileFirst Platform 7.0 documentation that JAX-RS support is now available on the MobileFirst Server and JAX-RS specification based Java adapters can be developed and deployed to the server.
Can I deploy the above mentioned webservice .WAR file as such to MobileFirst Server, without making any customizations?
If yes, what is the procedure for deploying the webservice (.WAR) to MobileFirst Server?
If no, what are the alternate options that can be considered?
As indicated in the comments above:
MFP Server is actually a Java EE application deployed to a supported Java EE application server, WebSphere Liberty or full WebSphere ND being the normal options, though TomCat is also supported.
In principle your own JAX/RS WAR file can be deployed to these same servers, the details will depend upon exactly what Java EE features you exploit and you will need to understand those Java EE servers' administration model. MFP itself is not affected by this, and you need no MFP knowledge to do it. You just need to understand the chosen Java EE server. Personally I would start with WebSphere Liberty.
A further question would be whether it is better to isolate your JAX/RS and Mobile First servers into their own Java EE server instances. It can be easier to manage and scale if you keep things separate, but technically there should be no interference if you do co-locate them. It is pretty trivial to spin up a dedicated Liberty server.
A more interesting question is whether there is value in actually exploiting the MFP Adapter capability to create JAX/RS services. In effect it's your familiar JAX/RS programming model but packaged slightly differently, deployed as a MFP adapter, and with the option explicitly to exploit the MFP security model and easily call other MFP adapters.
Personally, if I were coming to a project with no existing JAX/RS services and have commited to MFP and its security model then I would do my JAX/RS in the MFP Adapters.
