Document attachments in a form or process

Latest response

Hi,

I was trying to add document attachments based on https://access.redhat.com/documentation/en-us/red_hat_process_automation_manager/7.5/html/designing_business_processes_in_business_central/business-process-forms

The form specified a full directory in front of file name

I can attach a document in a form but the document was failed to be created in RHPAM:
15:03:41,462 ERROR [org.jbpm.document.service.impl.DocumentStorageServiceImpl] (default task-2) Error writing file D:\test\a.pdf: {}: java.io.IOException: Directory '.docs\388f4d34-b732-48d6-b898-d00fd8bb1cf3\D:\test' could not be created

Hi Rudyanto,

by looking at the path '.docs\388f4d34-b732-48d6-b898-d00fd8bb1cf3\D:\test' which is constructed from document storage path + document identifier + document name it seems that for some reason you specified the document name to be 'D:\test\a.pdf'. Can you specify the document name to be just a.pdf? Then the directory to save a document would look like '.docs\388f4d34-b732-48d6-b898-d00fd8bb1cf3' which is a valid path.

Hi Marian,

I have edited my post to show the form that I used to create the process instance.

This form is generated by RHPAM from a business process that was defined in BPMN. Do you know how to fix it so I can specify the document name to be just a.pdf?

Best Regards, Rudy

I have just tried the same scenario on Linux (Fedora) and the issue is not present there. So it seems it's an issue specific to Windows environment. I have created a JIRA to track this issue: https://issues.redhat.com/browse/RHPAM-3117.

Feel free to add any comments you have there. Thanks for letting us know!

Hi Marian,

Thank you so much. You have identified it as a bug.

One more thing. Maciej said that we can call Kie Server Rest API to upload document : http://mswiderski.blogspot.com/2016/08/kie-server-jbpm-extension-brings.html

But I did not find this address : http://localhost:8080/kie-server/services/rest/server/containers/translations/processes/translations/instances

I have tried to look at this url also : http://localhost:8080/kie-server/docs/ but I still can't find Maciej's URL.

Do you think it is another bug? Or now RHPAM has a new URL for it?

Best Regards, Rudy

Hi Rudy,

the URL is definitely there, but it changes according to your project name, so in general it looks like this:

http://localhost:8080/kie-server/services/rest/server/containers/{nameOfContainer}/processes/{nameOfProcessDefinition}/instances

Maciej's container and process definition were called translations in his example. You should alter the URL to your use case.

Hi Marian,

I bet you have an eagle eye. Others won't see what you means because your url is different with the one that was sent to my email adress. I think you should report it as a bug also :)

I will try my best to describe the link : http://localhost:8080/kie-server/services/rest/server/containers/ {nameOfContainer}/processes/{nameOfProcessDefinition}/instances

Best Regards, Rudy

Hi Rudy,

I tried to reproduce the issue by following the steps in the documentation you mentioned, but I'm unable to reproduce it in my Windows 10 instance. Can you please send us a video recording and details of your environment you are using.

Thanks, Abhishek

Thanks for the reminder, I didn't check the rendered response after I posted the message, corrected now.

I will post the video recording later.

My environment is : 1) Windows 10 Pro 2) JBossEAP version 7.3 3) RHPAM version 7.8

Hope you will find that error also.

Thanks, Rudy

Hi Abhishek,

I think you had found the problem and fixed it. Suddenly this problem is solved in my computer.

I guess RedHat had made patches for this problem. Well done :)

Thanks, Rudy
