How to get orapki without installing the full Fusion Middleware
I was asked recently if there was a way to get the orapki utility without having to install the entire Fusion Middleware. The answer is yes, sort of. So if you need access to this utility but for some reason are not able to use the one that comes with your application server, read on.

Java code hanging in JDeveloper while establishing a T3 connection over VPN with Proxy
It's not often that I work on my company's VPN but on this occasion I did. One of the things that I've forgotten about was how proxies are automatically configured when the Cisco AnyConnect VPN Client establishes the VPN connection. The reason I need to be on the VPN was to access some internal servers and run some of my code that connects via the T3 protocol to a weblogic server and executed some remote methods. Every time I executed my code it just sat there as if frozen.

Workaround for JDeveloper 12c Refactor Rename bug
I use JDeveloper on an almost daily basis and when something as basic and fundamental to the product as the rename functionality breaks, it makes you want to tear your hair out. I'm talking about the Refactor Rename feature that has been broken since the 12c release. Luckily there is a workaround.

JDeveloper 11g to 12c ADF Application migration causes deployments to fail with a ClassNotFoundException
I've been porting an older ADF 11g application to ADF 12c and used JDeveloper to do the migration for me, after a bit of code tweaking I tried to deploy the app only to find that it was failing with the java.lang.ClassNotFoundException: org.apache.myfaces.trinidad.webapp.TrinidadConverterELTag error. It took some time to find the culprit, so I've decided to share the fix.

SQLDeveloper 4.0.2 on OS X with the Mac L&F rendering issues
I've updated my SQLDeveloper to 4.0.2 and to my surprise found a major rendering issue with this version. The whole window is using black as the background, including the toolbar. This means none of the text can be read and the whole application is essentially useless then.

JDeveloper 11g and 12c do not support new Java 7 Syntax: Try With Resources
Now that Java 8 has been released, you would think that the IDE that comes from the makers of Java would support all of the language syntax that dates back to the Java 7 days, but alas it does not. I tried both JDeveloper 11g (11.1.2.0.0) and 12c (12.1.2.0.0) and neither appear to support the try-with-resources syntax that was introduced as a part of JDK 7. However, compiling the code has no problems, both IDEs are able to compile source code that is using this new syntax.

Changing the JDeveloper 11g IDE font size (not the Editor font) on OS X
I've been searching around on how to change the font size for the JDeveloper IDE and finally got it worked out on OS X. There are some forum posts on this but none that I could find that dealt with OS X specifically. So here's how to do it.
