Documentum – DA 7.3 showing java.lang.NullPointerException on every actions

By | Application integration & Middleware, Entreprise content management | No Comments

Last year, we started to upgrade some Documentum Administrator from 7.2 to 7.3 and directly after, we started to see some NullPointerException on the log files. We are using DA 7.3 on some recent WebLogic Servers versions (12.1.3, 12.2.1.2). We usually deploy DA as a WAR file (so not exploded) with just the dfc.properties, keystores and logs outside of it. This is the kind of errors we started to see as soon as it was…

WebLogic – SSO/Atn/Atz – Infinite loop

By | Application integration & Middleware, Entreprise content management | No Comments

This blog will be the last of my series around the WebLogic SSO (how to enable logs, 403 N°1, 403 N°2) which I started some weeks ago. Several months ago on a newly built High Availability Environment (2 WebLogic Servers behind a Load Balancer), an application team was deploying their D2 Client as always. After the deployment, it appeared to the tester that the Single Sign-On was not working when using the SSO URL through…

Alfresco DevCon 2018 – Day 2 – Big files, Solr Sharding and Minecraft, again!

By | Application integration & Middleware, Entreprise content management | One Comment

Today is the second day of the Alfresco DevCon 2018 and therefore yes, it is already over, unfortunately. In this blog, I will be continuing my previous one with sessions I attended on the afternoon of the day-1 as well as day-2. There were too many interesting sessions and I don’t really have the time to talk about all of them… But if you are interested, all the sessions were recorded (as always) so wait…

Alfresco DevCon 2018 – Day 1 – ADF, ADF and… ADF!

By | Application integration & Middleware, Entreprise content management | 2 Comments

Here we are, the Alfresco DevCon 2018 day-1 is over (well except for the social party)! It’s been already 2 years I attended my last Alfresco event (BeeCon 2016, first of its name (organized by the Order of the Bee)) because I wasn’t able to attend the second BeeCon (2017) since it happened on the exact dates of our internal dbi xChange event. Yesterday was the DevCon 2018 day-0 with the Hack-a-thon, the full day…

Alfresco – Unable to move/rename a file/folder using AOS

By | Application integration & Middleware, Entreprise content management | No Comments

When playing with the AOS implementation, a colleague of mine faced an interesting issue where he just wasn’t able to move or rename any files or folders. The creation and deletion were working properly but he was unable to move or rename anything when using a Network Location or a Network Drive. This environment was freshly installed with a front-end (Apache HTTPD) setup in SSL so we worked together to find out what was the…

WebLogic – SSO/Atn/Atz – 403 Forbidden, another issue

By | Application integration & Middleware, Entreprise content management | No Comments

Earlier today, I posted another blog with almost the same title but the similarities stop here. The thing is that when you access your application, there aren’t much error codes possible so if there is an issue, it’s often the same generic message that is being displayed on the browser. To get some background on the issue that I will present below, we are usually setting up the WebLogic Server, enabling the SSO on the…

WebLogic – SSO/Atn/Atz – 403 Forbidden, a first issue

By | Application integration & Middleware, Entreprise content management | No Comments

In a previous blog, I explained how it was possible to enable the SSO/Atn/Atz (SSO/Authentication/Authorization) debug logs in order to troubleshoot an issue. In this blog, I will show the logs generated by an issue that I had to deal with last month at one of our customers. This issue will probably not occur very often but it is a pretty funny one so I wanted to share it! So the issue I will talk…

WebLogic – SSO/Atn/Atz – How to enable debug logs

By | Application integration & Middleware, Entreprise content management | No Comments

Let’s say that you have an application deployed on a WebLogic Server and that the SSO/Atn/Atz (SSO/Authentication/Authorization) isn’t working or throwing a 4xx error code like ‘401 – Unauthorized’ or ‘403 – Forbidden’. How would you be able to know what is happening and how to solve it? Well the answer is always the same: enable debug logs, it is just a matter or choosing the right scope and choosing a way to do it…

Documentum – DFC traces setup & investigation

By | Application integration & Middleware, Entreprise content management | No Comments

When working with Documentum, you will most probably have to enable the DFC traces one day or another and then work with these traces to analyze them. The purpose of this blog is simply to show how the DFC traces can be enabled, which tools can be used to quickly process them and what are the limitations of such things. Enabling the DFC traces can be done very easily by updating the dfc.properties file of…

Documentum – Unable to stop an IDS configured in SSL?

By | Application integration & Middleware, Entreprise content management | No Comments

When working with the IDS, you might face some interesting behaviors as mentioned in the last blog I wrote for example. This one will focus on the SSL part of the IDS on the target side. On this blog, I will start with showing the content of our start/stop scripts and how it is working in non-SSL, then switching to SSL and try again. Therefore for this blog, I quickly installed a test IDS 7.3 using…
