Errors may occur while working in Scheer PAS. To facilitate troubleshooting, corresponding error and notification messages are displayed in the application. The overview of error messages allows you to identify possible causes and possible solutions. It also refers to documentation pages that contain further details.

If errors in the validation panel occur, try clearing the compiler cache. This could always helpful to resolve displayed compiler errors.

You can find the option in the additional menu of the Controls panel.

Validation Panel MessagePossible ReasonSolutionFurther Information

An error has occurred during the compilation of the project

This error is shown if the communication with the compiler failed.
  • Try to clear the Compiler vache and deploy again.
  • If the problem persists, contact the support team.

An error has occurred during the project data preparation

This error is shown if the code preparing the zip file for the compiler encounters an error.

  • Check your code for erroneous data or bugs.
  • If the problem persists, contact the support team.

javax.ws.rs.ProcessingException: java.io.IOException: Error writing to server

The deployment took to long and ran in a timeout.
  • Check if all service properties are set correctly. Reload the Designer and restart the deployment of your service.
  • Try to deploy the repository file directly in the integration component (Bridge), see Deploying a Service in the Integration Component for details.

REST interface classes: urn.AddressImplementation.Address.Public.Address, urn. Data_Model.com.Address share common class name 'Address' but class names in REST interface must be unique.

There are duplicate class names in your model.

Your BPMN model name (in our example: Address ) and a class of a BPMN message (in our example com.Address ) have the same name. Rename the BPMN or message class.

Version of the project ('21.2') is not compliant with semver format (major.minor.patch).

The version number of your service is not written in the correct notation.

Change the version number of your service. The number must follow Semantic Versioning 2.0.0: Major.Minor.Patch. A pre-release tag is optional.

Deploying a Service to the Integration Component

If the deployment from within the Designer keeps running into a timeout, you can try to deploy the compiled service directly in the integration component (Bridge).

Open the additional menu of the Controls panel and select the export option Compiled > Service.

This will download a file in .rep format.

Open the PAS integration component (Bridge).

Select the menu option Deployment and choose the exported .rep file of your service for upload.

In the next step, you can define if the service should be started automatically after deployment.

Click Deploy to start the deployment process. You will get a notification message when the deployment has been finished.

For more information on deploying xUML service repositories to the Integration (Bridge) and explanations on all options, refer to Deployment of xUML Services.

Go back to the Designer and reload the browser tab.

Check the Controls panel to see if the service is running: The icons to stop the service and to open the application should now be enabled.
