Software AG recorded a video with us on how we cope with the generational change that takes place in the Natural developer community. How do you handle the problem of aging Natural developers? I’d love to hear your comments on that! By the way, I’ll be talking about modern Natural development at IUG 2017! See … Read more
Error handling in Software AG’s Natural can be done in a way that resembles Exception handling in object-oriented languages like Java. throw Instead of throwing an Exception, you raise an error simply by assigning a value to the system variable *ERROR-NR. As soon as a statement like the following is executed, the current program flow … Read more
My JBoss EAP 7 server couldn’t cope with a failing database. After a database restart or failure, e.g. due to maintenance, it simply would not connect to the database again automatically. The application simply stopped working as soon as the database was unavailable for a short period of time. JBoss’s server.log was full of (not … Read more
Here’s a short subroutine for reading the physical file path of the current FUSER of a Natural (from Software AG) runtime. I’m not sure if it works on a mainframe, but it definitely runs on a Linux system. The subroutine returns the following information, if it runs successfully: P-FUSER-PATH /home/macke/fuser P-RC 0 Otherwise the return … Read more
One might think that joining (or combining) two file paths together with Groovy would be an easy thing to do. I’m used to “nice” methods from Ruby like File.join (see How to do a safe join pathname in ruby?): File.join(“path”, “to”, “join”) As it turns out, there is no such method in Groovy. However, here … Read more
After a few hours of trial and error and finally getting authentication against Google’s API working in Ruby I think it’s time for a blog post 😉 I had a simple (at least I thought it was simple) requirement: Reading the people in a user’s Google+ circles with Ruby. Because I use OmniAuth in my … Read more
Configuring JBoss EAP 7 to write an access log (e.g. like Apache webserver) is quite easy with the CLI: /subsystem=undertow/server=default-server/host=default-host/setting=access-log:add If you need any additional configuration, take a look at this: Wildfly 10.0.0.Final Model Reference. For example, to change the prefix of the log’s file name: /subsystem=undertow/server=default-server/host=default-host/setting=access-log:write-attribute(name=prefix, value=”my_access”) Alternatively, you could change the configuration in … Read more
Arquillian makes it easy to test your Java EE application on a real server. However, if you deploy an application, that uses a database to perform its tasks, how do you make sure a database with test entries is available on the target server? If you set up a “real” database on the server, the … Read more
