View 3 Replies View RelatedUbuntu :: Kate Editing Java File?
Jan 30, 2011I am a CS major and Iv'e been using vim with a custom rc file to do my editing... A professor suggested we can use kate with terminal for better speed so I thought I would give it a try. Unlike vim, geany, eclipse and others kate does not indent java code, for example after "{ <ENTER>" it should indent to the right 1 tab, but it does not, so I have to press <TAB> every time I go to new like, and I have to go back and forth for different statements...
This does not make things faster at all, Is this even possible? Any other editor suggestions that do not use GTK, but kde native Qt with terminal emulator?

Ubuntu :: Creating Link To A .java File With Parameters
Oct 24, 2010I have a Java program (minecraft server) that needs to be run from the command line. The code is:
Code:
java -Xmx512M -Xms512M -jar minecraft_server.jar nogui
To make life easy (i've got the java file in a folder on the desktop) I want to have a shortcut (or similar) sitting on the desktop. I've tried
Code:
ln 'java -Xmx512M -Xms512M -jar minecraft_server.jar nogui' ./../minesraftserver
with single and double quotes but my unix command line skills are pretty basic and this is obviously incorrect.
Ubuntu :: Create Launcher For Java File As Root
Dec 25, 2010I have a java.jar (PCGen) that only works correctly if I run it with sudo from the terminal. I have to cd into its directory and run it as
Code:
sudo java -jar pcgen.jar
I would like to use a menu launcher instead of having to use the terminal each time. I tried
Code:
sudo java -jar /path/to/file/pcgen.jar
No luck. This .jar only works properly if ran as root, is there any easy way to do this?
Ubuntu :: Java File Doesn't Run Over The Command Line?
Jul 13, 2011I have bound over the command line all for my work related jar files to my CLASSPATH

/workspace/JenaTutorial/src/main/java/tutorial$
But there are still one problem; although my java file can run in Eclipse environment without any problems it does not run over the command line:
//workspace/JenaTutorial/src/main/java/tutorial$ java HelloRDFWorld.java
Exception in thread "main" java.lang.NoClassDefFoundError: HelloRDFWorld/java

View 4 Replies View RelatedUbuntu :: Install Latest Java Version - Java SE 6 Update 24?
Feb 18, 2011If you are interested, Java SE 6 Update 24 is available. The Check Java Version link in my signature will tell you if you are up to date or not. The Update Java Version link in my signature will tell you how to obtain and install the latest version. The 32 bit version install directions are on the left side of that page and the 64 bit instructions are on the right side.
Just remember to remove the current version before installing the new one as it says in the instructions. The remove instructions are below the install instructions. Also, in Step 9 - "Now you'll want to tell the system, that there's a new Java version available." See the note below it that says if you get an error upon entering the command once, enter it a second time. I have to do that and sometimes forget. Just thought I would mention that. These instructions are already setup for version 6 update 24, but they can be modified for any update and they will work. I have been using these instructions for a couple of years and they work.
General :: Java / Applying Elevated Permissions When Running A Particular .jar File?
Apr 11, 2011regarding user permissions:
I have user A who owns a .jar file
I have user B. who needs to run the .jar file
I have Java which is owned by root.
I would like to work out whether/how user B can run the .jar file, in Java, with the permissions of user A. As I understand it, a running process in Linux typically takes the permissions of the user who executes it. However, the way I'd like to configure user B, the permissions I want them to have wouldn't be sufficient for the process to successfully run.I know you can also set a process to take the permissions of the owner of that process, but in this case the actual... executing process would be Java, which runs the .jar file, and I def. don't need this, let alone every single instance of Java on my server, to execute with root priviledges. So like I said, basically I am trying to work out how to let user B run this specific process with the process elevated to this set of priviledges which user B otherwise does not have.
I recently started running a Minecraft server for myself and some friends and am running it via Linux. I'd like to set things up so that a friend of mine can, as needed, telnet into the server and restart Minecraft as needed, as well as a couple of other things, without giving this friend the same access rights I've given myself to the same files. The minecraft server process runs in a screen, and I've worked out where screen can be set up so multiple users can get into it. However, if I'm running minecraft under my own user name, then that seems like it will just end up letting my friend, from his account, screen into my own account. SO the brilliant idea I had was, what if I had one user account which only existed to run the server, which both me and my friend could screen into as needed, which wouldn't have any more rights to anything than my friend has with the exception of being able to execute this one .jar in Java.

Slackware :: Installing Java Error - When Trying To Run A Java App With The Firefox Plugin - Browser Crashe
May 29, 2011Code: ~ $ /usr/java/jre1.6.0_25/bin/java -showversion Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object
That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.
