Complete Task from REST

Stelt0 — Mon, 07 Oct 2019 09:40:24 -0400

Hi Ivy Team,

How to complete a task from REST service in Axon.Ivy ?

So, far I saw that I can do .destroy() but it doesn`t feel the right, I believe that there will be some side effects

.setActivator(ivy.session.getSecurityContext().getSystemUser()) but this way I`m loosing the history who was the assignee of the task

Any other options ?

Maybe to do HTTP call to the end-point /TaskA.iot?taskId=7

My goal is to build REST API that can manage the Axon.Ivy tasks from external system.

Java Api for Start Process Signature variables

Stelt0 — Tue, 17 Sep 2019 09:38:57 -0400

Hello IvyTeam,

Is there a way to get the list of parameters which are defined in the Signature of a process start element ? *I need this information before starting the process instance.

I checked the public API but such information is not available. So, I assume there is an Internal API that I can use ? Can you provide some code snipet?

Ports opened by the Engine

Stelt0 — Fri, 29 Mar 2019 02:59:06 -0400

Hello Ivy Team,

Do we have somewhere a list of all ports that Axon.Ivy Engine is opening ? I know only for the HTTP(s) and AJP ports. Do we have others that are opening behind the scenes ?

We found a port conflict with another application on port 9999 on one of our instances. I was not aware that this port was used by the Engine and I don`t know where to configure it.

I found only this occurrence in the settings:

How can we configure this one to listen on another port ?

Engine mimimum system requirements

Stelt0 — Fri, 05 Jan 2018 09:48:30 -0500

Hello, Ivy Team,

I was trying to find in the documentation what are the minimum system requirements for axon.ivy 7.0 engine (CPU, RAM, HDD). My goal is to have simple demo environment.

Let say, I want to install it somewhere on Amazon on VM with 1 CPU hosting on windows 2012 with MySql. Would be possible to run with 512 RAM or am I to optimistic ? :)

Migration Ivy Server to another Machine

Stelt0 — Tue, 21 Nov 2017 08:29:28 -0500

Hello, Ivy Team,

We are planning to move one existing installation of Axon.Ivy Server to another machine. What are the pitfalls in such scenarios?

We will copy-paste the whole installation folder to the new server (the file system paths will be the same)
We will attach the AxonIvySystemDatabse to the new server (p.s. we will also migrating to different db server)
We need to change the license file
We need to update the configuration to point to the new db server
Probably we need to update the server name in the Admin UI

All should be straightforward, right ? Are we missing something ?

End Page on User Dialog

Stelt0 — Tue, 26 Sep 2017 04:27:51 -0400

Hello Ivy Team,

I have a business process starting with an User Dialog, where the user can submit a request. After that the process is doing a lot of background activities and it is assigning tasks.

The application is part of the Portal application. Currently, when the user submit the request, he is redirected to the Task List of the Portal.

Is it possible instead of redirecting int to the Task List, to show him some Thank You page ? The problem is that this process can be started by users that does not have Ivy user and in this case he is redirected to the Portal Login page. For these users this makes no sense.

Source Control for Axon.Ivy project

Stelt0 — Wed, 23 Aug 2017 02:20:58 -0400

Hello Ivy Team,

Do you have any advise what is the proper way to setup SVN and Git in order to manage the code ?

I see that the files in \src_dataClasses and \classes folders are deleted (including the .gitignore inside) Also the files inside .settings folder should not be watched for changes, but they need to be part of the initial commit (they contains passwords for the email server in clear text !)

Engine stettings store

Stelt0 — Mon, 24 Apr 2017 08:08:34 -0400

Hello, Ivy Team!

I`m looking for a way to restore the default server setting of the Engine manually.

I have found the table that stores the default values: SELECT * FROM public.iwa_systemproperty

can you tell me where I can find the applied configurations ? are they in another table or in a file ?

p.s. I need to restore the manually, because I accidentally changed some of the address settings and the AdminUI is not longer accessible for me.

How to get url for Task in Email

Stelt0 — Thu, 06 Apr 2017 08:30:18 -0400

Hello Ivy Team,

I`m building a process for overriding the default email notifications as described here: http://developer.axonivy.com/doc/latest/EngineGuideHtml/administration.html#administration-applicationdefaults

I have a problem to build an URL to the task.

I`m trying this ways, but no luck:

in.task = ivy.wf.findTask(in.notificationTaskId);
in.taskUrl = ivy.html.taskstartref(in.task);
in.taskUrl = ivy.var.FQDN + in.task.getFullRequestPath() + "?taskId=" + in.notificationTaskId.toString();

the URL is valid but the Id of the task is different than in the Task List view.

I`m using version 6.4

Am I doing something wrong or this is a bug in this version ? p.s. it does not work bot on the Designer and on the Server

Eager Loading

Stelt0 — Wed, 21 Dec 2016 09:19:58 -0500

Hello Ivy Team,

In my project, I had to switch from the default Eager loading to the Lazy loading of the Entity classes. The reason was that the queries were not optimized. Now I have the following problem, every time I try to inspect the variables in debug mode, the Designer is throwing errors and it is almost impossible for debugging:

CMS Other type of resources

Stelt0 — Wed, 17 Aug 2016 08:01:01 -0400

Hello All,

Is there a reason why I can store on the CMS so few file formats ?

For example: I can store .css files, but not .js files I can store .png and .jpeg but not .svg

I would also want to be able to store font files, audio and video files, etc..

Does Ivy Team has a vision to extend the list in future releases ?

Axon ivy mobile experience

Stelt0 — Mon, 08 Aug 2016 10:26:03 -0400

Hello Ivy Team,

I want to provide some mobile experience to my users.

There are currently 3 approaches in my head:

1.Native Mobile Client - Native iOS and/or Android app - no Web View - communicating to Ivy via HTTP - only data returned, no HTML - offline support

2.Hybrid Mobile Client - Phonegap or Ionic HTML SPA hosted on the device (web view) - communicating to Ivy via HTTP - only data returned, no HTML - offline support

3.Mobile optimized web view - OOTB provided by Ivy web technologies - JSF and PrimeFaces - no offline support

Option 3 is the easiest to implement and release, but it has the worse UX. My biggest concern for option 1 and 2 is the security in terms of session management.

Witch approach would Ivy Team recommend ? I saw in the documentation about the Offline User Dialogs, but they goes to option 1

Error handler redirect to Web Page or User Dialog ?

Stelt0 — Thu, 04 Aug 2016 14:38:50 -0400

Hello All,

I have an interesting situation.

I have a User Dialog with interactions and a bit complex Logic. There is a point in the process where I`m trowing an exception and I want to redirect the user to an error page:

I want to catch the exception in the business process where to do the redirect. Here is the confusing part:

If I redirect to User Dialog, everything is working correctly:
If I redirect to Web Page (JSP from the CMS) it is trowing an error.

Is this a bug or wrong architecture from my side ?

anyway, what is the best practice for managing exceptions in User Dialog`s Logic?

Entity Class Migrations

Stelt0 — Wed, 06 Jul 2016 10:08:37 -0400

Hello Guys,

I`m new to Hibernate and JPA. I have an Axon.Ivy project that has couple of Entity Classes. I want to move them in a separate project and separate namespace(package) and also to add some additional fields.

What are the implications when I`m changing the data model and the namespaces ? How do I migrate the changes to the production server ?

In .Net Entity Framework there is a concept of 'migrations' where the changes to the database are applied automatically when the code is deploys.
