A namespace prefix is not registered - Simple OCR

[anoopkr]

Hi,

In our 6.2 installation we have or rather had this OCR module (2.3.1) it worked flawlessly. We are now migrating the 6.2 to latest version, we did it through version 7 and all are working (seemingly) fine, except, in Workspace application and error comes at certain entries, "This item no longer exists or you don't have permission to view it. ", the error log says  " A namespace prefix is not registered for uri http://www.keensoft.es/model/content/ocr/1.0". We had removed the jar files and global-properties entries related to OCR and all the folder rules before taking the backup of both content store and DB in 6.2 and we suspect this could be the error. Someone please help to tackle this issue, apart from this everything looks okay.

An excerpt from the log file.

Hi,

Thanks for the response, the rules I was talking about the rule we need to set to the directory so that whenever a file (say pdf) gets OCRd. And, about the link you shared, that was the project I was trying to implement. But what you mentioned is for "docker", isn't it ? Ours is a zip based installation (Using Mr Angel Borroys scripts) and  I was told that it is possible to implement it. But all efforts did not fruit. Im sure you can help, so pls guide me.

Hi,

If I delete the nodes, will it solve the issue we mentioned ? If so can you tell me how ? Then I can follow the link you provided for OCR

Regards

[anoopkr]

Hi,

Pls let me know how to delete the nodes.

You will have to keep the jar file or deploy only the content model in a custom project to delete the nodes.

You can use a simple search and delete using share, or create a custom javascript to do that.

But if you need the documents that got the OCR applied, it might be better to simply search and remove the ocr:ocrd aspect only, as by doing that, all the documents will be kept in the repository.

As soon as the aspect is removed from all the documents, it will be safe to remove the jar file.

[anoopkr]

Hi,

Many thanks for the response, If I keep the jar in place it gives me errors and Alfresco would not let me to log-in. Actually all I need the data intact that I can transfer to a newer version, OCR and other services I don't care, at least for time being. Is it possible ? Other than OCR we had a few others as well, like "folder quota" etc, they too are making issues, I hope following OCR I could solve other issues as well. We are not experts in alfresco or java, but in the past we have somehow resolved all the issues by googling and using forums, so the abstract answers I get are a bit difficult to comprehend and I am perfectly aware that an elaborate answer is not possible as well.

Regards

[douglascrp]

In that case, you could simply extract the content model for the ocr, and put it in a custom module, and use this one to deploy into your server.

By doing so, you will have only the content model available, without the custom beans causing the issues.

I guess the same applies for the folder quota, as that one also uses aspects to keep the quota values, and the custom beans are probably the ones causing the issues you are facing.

[anoopkr]

HI,

I tried this with the folder quota, but failed. It breaks Alfresco I cant even log in.

Adding some logs.

I don't know which addon you are using exactly, but I guess it's this one https://github.com/bhagyas/alfresco-folder-quota

If that is the case, the exact bean you have to comment in order to have it working is this

https://github.com/bhagyas/alfresco-folder-quota/blob/master/folder-quota-repo/src/main/amp/config/a...

[anoopkr]

Hi,

Lots of thanks for the tip that actually worked, the quota application is different but following you I was able to resolve it, now the error is disappeared (Error in displaying the User home content in Alfresco workspace application, while Alfresco share was working OK)

That leaves me with the original issue I posted, the OCR issue. I tried everything similar to the folder quota issue but none of them worked out, if you can look through my logs you shall be able to guide me, I shall attach them below.

Regards
