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 – 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…

How to rename an existing Fusion Middleware WebLogic Domain

By | Application integration & Middleware | No Comments

Some times it happens that we need to rename an existing fusion Middleware WebLogic domain. I was asked to do such on a Fusion Middleware Reports & Forms environment. I took some time to check how this can be done and did some testing to confirm it works as expected. The difficulty is not the WebLogic Domain itself as a WebLogic domain can be created quickly but it is time consuming if the complete configuration…

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 story – Unable to start a new Managed Server in SSL in WebLogic

By | Entreprise content management | No Comments

Some time ago, I was creating a new Managed Server named msD2-02 on an existing domain of a WebLogic Server 12.1.3.0 created loooong ago and I faced a small issue that I will try to explain in this blog. This Managed Server will be used to host a D2 4.5 Application (Documentum Client) and I created it using the Administration Console, customized it, enabled the SSL with internal SSL Certificates, the SAML2 Single Sign-On, aso……

Documentum story – Replicate an Embedded LDAP manually in WebLogic

By | Entreprise content management | No Comments

In this blog, I will talk about the WebLogic Embedded LDAP. This LDAP is created by default on all AdminServers and Managed Servers of any WebLogic installation. The AdminServer always contains the Primary Embedded LDAP and all other Servers are synchronized with this one. This Embedded LDAP is the default security provider database for the WebLogic Authentication, Authorization, Credential Mapping and Role Mapping providers: it usually contains the WebLogic users, groups, and some other stuff like…
