Stub class not found. Why’s that?

Since my early days with Java many stuff have impressed me but, among the things that impressed me the most, is the Remote Method Invocation (RMI). It makes it very easy to create applications over a network. One hard part about it was that we had to create what we call “Stub files” for each class that was published on our registry (a.k.a. Remote objects). Since JDK 5 though this was history. One of the new features was that the Stub class was generated automaticaly and no further action was needed…, or not quite like that? (more…)

PDF file specification

Now this is something i didn’t know. I always thought that the PDF files are just jibberish bytecodes. This is not absolutely wrong but most of it is not right… What actually happens is that PDF represents documents as structured data. (more…)

Firefox about:config

It’s been a few years since i stumbled uppon this page in Firefox. This browser is so configurable that just amazes me everyday! Well what i did is i downloaded a plugin for firefox, the vertigo plugin to be exact. What it does is that it lists all the open tabs verticaly just like the favorites. This is usefull on the one hand but i totaly lost the tab bar on the top when i installed. Moreover no “X” was there so i could easily close the tabs. So, after 2 minutes of trying it out i figured it was not for me. I uninstalled it and restarted firefox. Then the top bar reappeared BUT there still was to “X” on the top right of the tab to close…! I went through the settings but there was no option like “Show the stupid “X” sign on the top!“. And then it came to me. I opened a tab and typed “about:config“. Then, on the filter, i typed “tabs” and there it was! There is a setting “browser.tabs.closeButtons” and it was set to “2“. I changed that back to the default value “1” and the “X” appeared again! Nice huh? And this is not the only one. You can find many many settings of how firefox works and behaves. So, check it out!
