Hello Ryan,
I ran into problems installing mediator. I installed grunt because section 3.4 ( Message adaption using a mediator) requires me to run a grunt task.
When I ran "grunt server", I received the following error messages.

>> Local Npm module "grunt-contrib-watch" not found. Is it installed?
>> Local Npm module "grunt-parallel" not found. Is it installed?

And then the following error was issued:

Running "express-server:custom" (express-server) task
Fatal error: Server ["...\openhim-console-1.4.1\tutorialmediator\build\index"] - SyntaxError: Unexpected end of input

Q1/ Should "grunt-contrib-watch" & "grunt-parallel" modules be part of grunt install or it is from a different package? I had updated nodejs after I installed Grunt. So these missing modules messages are weird.
Q2/ Is the above fatal error related to the missing modules?

Thanks in advance.

Hello All,
I am still stuck at this error when I tried to run "grunt serve"

Fatal error: Server ["..\openhim-console-1.4.1\tutorialmediator\build\index"] - SyntaxError: Unexpected end of input

Even if I ignored the prompts regarding missing modules for "grunt-contrib-watch" & "grunt-parallel" (in my previous post), it seems to me problem resides within this index.js file.

I have uninstall and reinstall various node, grunt, yeoman modules for the past few days, to get rid of the missing modules warnings, same result.

Has any one build this latest mediator module from scratch successfully? Would you like to share your thoughts how I can over come this issue?

Thanks.
PS. I attached index.js from "..\openhim-console-1.4.1\tutorialmediator\build\" folder for your reference.

Hi,

Sorry this response took to long. Did you start with this step: http://openhim.readthedocs.org/en/latest/tutorial/3-creating-a-passthrough-mediator.html#nodejs-mediator

It should set things up for you. What do your package.json file and gruntfile look like? Also, please note the command is 'grunt serve' not 'grunt server'.

Cheers,

Ryan

Hi

Have you managed to get the OpenHIM successfully installed and running or do you still require some implementation help. I can try and assist you in getting it up and running if you are still experiencing issue.

Warm Regards,

Martin

Hello Martin,
I think I narrowed down my current problem of not able to setup mediator correctly to the file "index.js"
I followed Ryan's link to: http://openhim.readthedocs.org/en/latest/tutorial/4-message-adaption-using-a-mediator.html#nodejs-mediator
I examined the pdf file (R1.3.0) from Jan of this year.
The content is different in on P24 of the above pdf and that from the URL link. I had been following the pdf's instructions & I got stuck.
Can you email me a working copy of the index.js file? I am running into problems with this file.
Thanks in advance.

Hi Sorcerer

I have attached a working index.js file which i created/tested the Message Adaption mediator. If you can maybe just confirm that you have below setup:

OpenHIM Core and Console
The Tutorial Services are up and running. ( http://openhim.readthedocs.org/en/latest/tutorial/1-getting-started.html ) The link to the Tutorial Services zip seems to be broken but will be fixed shortly. In the meantime I've attached the scripts in-case you might not have them.
Tutorial Services can be reached by making a request through the OpenHIM core
You have created a NodeJS mediator using the Yeoman Generator as explained in the documentation ( http://openhim.readthedocs.org/en/latest/tutorial/3-creating-a-passthrough-mediator.html )

If you have all the above setup correctly you should just be able to replace the index.js file with the one attached. You might have to do a npm install to get the needle package that gets used in the updated script.

Let me know if you are still experiencing any issues getting the mediator working.

Warm Regards,

Martin
