ServiceTask | Android中ServiceNotification断点续传下载

Your process model contains a user task with implementation type Java Class. The Java Class name is set to: *.Cron So, when you run the process the engine is trying to find and instantiate a class of this name.

https://docs.camunda.org/manual/latest/user-guide/process-engine/delegation-code/

To implement a class that can be called during process execution, this class needs to implement the org.camunda.bpm.engine.delegate.JavaDelegate interface and provide the required logic in the execute method. When process execution arrives at this particular step, it will execute this logic defined in that method and leave the activity in the default BPMN 2.0 way.

You need to change the process model to reference a class which actually exists (https://docs.camunda.org/manual/latest/reference/bpmn20/tasks/service-task/) or use another implementation approach.

Your Docker image is likely based on Camunda BPM run. In this distribution additional jars can be placed in the userlib folder. https://docs.camunda.org/manual/latest/user-guide/camunda-bpm-run/ However, since you do not seem to be right at home in the Java world, you may want to consider a different approach to invoke your service. You could for instance change the implementation of your service task to a script tasks or to an external service task

CSS 'content' uses the hexadecimal entity of a character (http://www.evotech.net/blog/2007/04/named-html-entities-in-numeric-order/). Your example hex \e856 is 59478 in decimal (https://www.rapidtables.com/convert/number/decimal-to-hex.html)

The Camunda Modeler uses BPMN.io, which uses its own font to define the BPMN symbols (https://github.com/bpmn-io/bpmn-font). The font elements (icons) are defined here: https://github.com/bpmn-io/bpmn-font/blob/master/resources/font-config.json

Unfortunately I made a mistake while creating the object 'OSM' as there is a little Bitmap created depending of the state of a value.

The assignment of the Bitmap inside the 'OSM'object causes the exception.

The solution for this is to 'Freeze()' the Bitmaps: async load BitmapImage in C#

In my case it looks like: (Shortened Version)

For documentation purpose:

The problem was in the token file itself. When you change the scopes you need to make sure to get a new updated token. If you still use the previous token is like haven't changed your code at all.

The approach that you currently have with the ServiceFactory is essentially an Abstract Factory since you are encapsulating the creation of a related set of objects behind a method.

There are a few different ways that you can achieve similar results with dependency injection. One of the main benefits that you would gain by doing this is that you no longer need to manually construct any of your Service classes. Here are some examples using the .NET Core DI framework:

You can register Func which would take in a string and return an instance of IService:

One of the attributes 'class', 'delegateExpression', 'type', or 'expression' is mandatory on serviceTask.

What does your POM look like? Have you included these additional dependecies?

You can archive this by using the following example:

You can't create an array as a for loop inside the array. You need to do it a line sooner.

It's seems to be a bug with an empty collection.

Quote from Activiti Ticket tracker (Issue 748):

I am facing a new issue with multi instance tasks which are failing with PvmException("already taking a transition") when the collection over which we are looping becomes empty at any point after looping.

You should try to create a new non-modifiable list before the loop. After checking that the original list not empty create a new list for looping.
