Create folder and document using OpenCmis 0.2.0

[achillies]

Hi,
I am using the below code to create a document and to upload a file.
This code used to work fine with OpenCmis version 0.1.0 without the Alfresco OpenCmis Extension. When I upgraded the version of OpenCmis I started getting Internal Server Error. I have been tried using the Alfresco OpenCmisExtension but I cannot seem to get it to work. Any help on how to get it to work is highly appreciated. I have also tried to use the folder.createFolder method.
I am using the alfresco repository version 3.4.0(b)

Hi,

Could you please catch a CmisBaseException and post the string that getErrorContent() returns?
It should contain a clue of why it is failing.

Thanks,

Florian

Thanks a lot for the prompt reply. I did as you asked me to.
While trying to create a new folder I get

Unable to retrieve content: Connection reset

and while trying to upload a pdf file I get

It would be of great help if any of you could provide me a solution to it or correct way to create a folder or upload a document.

[fmui]

Are you using a (debug) proxy server? Some proxies don't handle chunking properly and lose content.

Can you create a file custom-log4j.properties in …/tomcat/shared/classes/alfresco/extension and add  the following line:

log4j.logger.org.alfresco.repo.transaction.RetryingTransactionHelper=debug‍

It should provide some more information in the log file.

Hi,
I have tested your code. The code has no issues.
May be you are using wrong versions of jar or just make sure you don't have "test" name folder in the
root of repository.
You should have alfresco-opencmis-extension-0.2 jar and chemistry-opencmis jars for 0.3.0 version.
Hope this will help you.
