Have you updated your PC with new Java 8? Are you using
glassfish3 because of unstable glassfish 4 or support or any other reason? Now
you will face problem as there is no option to run the glassfish 3 on JRE8. If
you have earlier JDK too, you will get the error of 'Unsupported major.minor version' during the deployment of app with new jar (compiled
with newt JDK ). Here is a little trick I have done to do so –
I’m a diehard fan of intellij idea. I also developed few android
apps on idea. Just missing the UI drag and drop option but it will come in the
version 12. Already preview option is
available from version 11. There are some projects on going in my office and I
have to use eclipse, so I have to know the shortcut of eclipse. But suddenly I
found an idea key scheme for eclipse. Download
the latest jar from the following URL –
Few people told me why are you using idea, it is not possible to create jar from it. Actually this idea about idea is totally wrong. To make a jar from idea go to
File -> Project Structure -> Artifacts
Then click the plus sign to add a jar setting. The “Create Jar from Modules” window will appear. Select the module and main class.
1) Choose extract to the target jar to include all the library jars include in your jar. Then press Apply and Ok. After than you will see a “Build ‘moduleName.jar:’ artifact” option in Build menu. It’s simple.
Or
2) And if you choose “copy to output directory and link via manifest” the edit the manifest to locate the library jars in Class-Path tag ex-(lib/one.jarlib/two.jar). Remind that if you execute the jar from a folder which folder is located in the project root directory and your library jars are located on a “lib” folder which is also in the root project directory, then add class path like (Class-Path: ../lib/one.jar ../lib/two.jar)
Did you watch the movie Matrix? I think the answer is obviously yes. I am a very good fan of that movie. After watching this movie, my Linux theme, wallpaper , screensaver changed to that theme, specially the terminal. I use Konsole with Green and black schema. So it is a little bit fuzzy when I use “git diff” with default auto color system of git. So I customize the color by editing the “.gitconfig” file on my home directory.
[color] ui = auto [color "branch"] current = yellow reverse local = yellow remote = white [color "diff"] meta = yellow bold frag = magenta bold old = red bold new = white bold [color "status"] added = yellow changed = red untracked = cyan [user] name = Towhidul Haque Roni email = towhid@xyz.net
I was working on a renowned XYZ software company. They prefer IntelliJ IDEA as a IDE. My senor collogue give me some task and I was working on the IDEA. He found the IDE is too slow and suggest me to increase the virtual memory. So I have change it in the “idea.vmoptions” file located on (/idea/bin). ====================================== -Xms700m -Xmx1024m -XX:MaxPermSize=450m -ea ===================================== But it seems too slow for scrolling the codes on IDEA. Then my senior suggests me to use version 6 instead of version 8. But I was working with IDEA 8 and looking for a solution. Suddenly senior bro came to me and wanted to see my progress. When he found IDEA version 8 he became angry and warn me he will delete all my code. I was so scared though I have IDEA local history and git ;) . Then I suddenly found the solution that it frequently uses graphics card but I know that it is not NFS(my favorite game :P) so I can disable that by including -Dsun.java2d.pmoffscreen=false At the end of the “idea.vmoptions” file. And the problem solved :D
