Print REMOTE_USER CGI Variable in JSP on WebLogic 11g

AshokTechnical Tips1 Comment

There could be a number of reasons you want to verify the value of the REMOTE_USER variable in an app you are running in WebLogic. A quick way to check is by dropping in a JSP file that prints the value: <html> <body> REMOTE_USER: <%= request.getRemoteUser() %> </body> </html><html> <body> REMOTE_USER: <%= request.getRemoteUser() %> </body> </html>

Registering Oracle HTTP Server with Oracle WebLogic Server

AshokTechnical Tips1 Comment

For Fusion Middleware Control to be able to manage and monitor Oracle HTTP Server instances, they must be registered with the domain. To do this, you must register Oracle HTTP Server with Oracle WebLogic Server using the following command: WEBHOST1> cd ORACLE_INSTANCE/bin WEBHOST1> ./opmnctl registerinstance -adminHost -adminPort 7001 -adminUsername weblogic

Using Oracle ADF EJB PersistObject

Ben MarckTechnical TipsLeave a Comment

While demoing out some ADF faces functionality to the team, I forgot that in order to build a form to save an object to the DB using the persistObject method you should… 1. Build the ADF Parameter Form using the Object’s Constructors from the Data Control. 2. Bind a button to the persistObject data control….. drag the persistObject data control onto the page and select ADF Button. 3. On the Action Binding screen, in the value column provide #{bindings.ObjectIterator.currentRow.dataProvider} as the value for parameter or use the EL builder to find the Iterator used by the form and bind it … Read More

ADF Table Row Selection Event Update Form

Ben MarckTechnical Tips1 Comment

One of the UI requirements in a recent ADF project was to use an ADF Read-Only Table and its built-in functionality (row selection, filtering and sorting) to allow a user to find a row, select it, then automatically have a form on the same page be updated with the data from the row selected for updating and saving. Let’s run though how to implement this… 1. Build the ADF Read-Only table by dragging the appropriate data control onto the view. Ensure you enable the appropriate ADF behaviors on the Edit Table Columns screen. Row Selection is required, but Filtering & Sorting is optional … Read More

WebCenter 11g PS3 on WebSphere

AshokIndustry Trends, Technical TipsLeave a Comment

I was slightly excited about WebCenter 11g PS3’s ability to run on IBM WebSphere — not because I run WebSphere, but because it could open the doors for WebCenter at places that run an IBM infrastructure. I was disappointed to find that I couldn’t even download the WebSphere trial from IBM’s site (see the accompanying video). Ironically, the [WebSphere] server that is serving the download produces an Internet Server 500 error. Yes, I verified that others also received the error. I’ll stick with WebLogic for now.

Oracle ADF vs. Other Java Web Frameworks

Ben MarckTechnical TipsLeave a Comment

To extend on an earlier blog posts by a colleague here at M&S, I’m a firm believer in using different technologies in different situations. Trying to make a technology ‘work’ when another is clearly a better choice is very often a critical mistake. Reasons why these decisions get made are numerous (familiarity with a technology, existing infrastructure, etc). With that said, my own take on ADF vs. other Java web frameworks (such as Grails) is actual a lot more black & white than I thought it would be. While ADF enables typical CRUD functionality quickly and efficiently, it’s abstraction from the … Read More

AshokNews and Updates, OfferingsLeave a Comment

We just started into installs for four middleware servers for a customer. These will each run DB, WebLogic, IdM, SOA/BPM, UCM, and WebCenter — all 11g. There’s nothing like getting fresh, fast, functionally-useless hardware and turning it into a powerful piece of problem-solving equipment. – Historic M&S Dogma

Oracle ECM vs UCM — What’s the difference?

AshokBusiness Strategy, News and Updates, Offerings, Technical Tips4 Comments

I’m starting to see Oracle ECM get mixed with Oracle UCM more these days when people talk about Oracle’s Content Management offering(s). Sometimes I wonder if this kind of confusion isn’t premeditated by marketing managers, but that’s another story. So, here’s the scoop (and though I say this confidently, I find myself compelled to disclaim that this is the scoop as I understand it, and as Oracle is using these terms as of the date of publication). For starters: ECM stands for Enterprise Content Management UCM stands for Universal Content Management “Oracle Content Management” offerings are also referred to as … Read More
