In this post I’m going to show how to adjust WebLogic logging levels using Enterprise Manager (EM). I will take as an example tiny demo application for logger demo, which I’ve introduced in my another post – How to add custom logging into ADF application? So this can be done in domain server context. Here is how to reach it: Click…
Where to look for log records in WebLogic Enterprise Manager (EM)?
In my opinion Enterprise Manager delivers the most convenient way to check log records. It has search and filtering capabilities. It works reliably and provides nice structured information. So where to find them? Lets use tiny sample application which I’ve introduced in my previous post – How to add custom logging into ADF application?. After deploying it to WebLogic server, please…
How to add custom logging into ADF application?
Can’t imagine development without logging. Even in ADF 🙂 For some quick output into local WebLogic console – System.out.println is quite ok. But if we need to have it in more professional and persistent way – java logging tools come to action. In ADF we have ADFLogger class at our service.

Is extremely big or low date, indicating infinity safe in SQL?
This is a question I’ll try to answer here. Quite frequently it happens to face SQL code, where extremum dates take place. From a first glance it look OK to use like to_date(‘3000.01.01′,’YYYY.MM.DD’)) for indicating infinity, something that lasts forever.

How to execute java expressions programmatically in ADF ?
Expression Language (EL) in java is powerful and convenient way to access necessary objects. In ADF it is commonly used as well. I suggest you a couple helper methods to execute methods and get values via EL: You may also need to pass parameters to method invoked by EL. Apparently EL does not support that. But there is a workaround,…
How to get LOV value instead of index when it is used in standalone ADF “selectOneChoice” component ?
Its a common issue in ADF to get a LOV value instead of index in ADF form. How to do that in collection context, for example – when we have “selectOneChoice” in table row cell, I’ve noted in another post. And that was really easy. Its more complicated when we need the same in “selectOneChoice” used in form, standalone component…
