Java Plugin for Firefox on Linux
I hit a page that had a Java applet and got the following "Missing Plugin" message.
Basically, my browser - firefox was unable to locate a Java Plugin needed to execute the applet on the page. It also gave me an option to "install the missing plugin" which essentially involved downloading a complete JRE which would take time. However, since I already had the latest JRE installed on my system, this is how I went about configuring firefox to use the same.
1. View the contents of the firefox plugins folder to look for existing/older Java plugins (if any)
abhi@abhiltlnx(~)$ type firefox
firefox is /usr/bin/firefox
abhi@abhiltlnx(~)$ ls -ll /usr/bin/firefox
lrwxrwxrwx 1 root root 25 2008-02-08 03:05 /usr/bin/firefox -> ../lib/firefox/firefox.sh
abhi@abhiltlnx(~)$ ls -lth /usr/lib/firefox/

total 24K
-rwxr-xr-x 1 root root 22K 2007-09-25 00:22 libnullplugin.so
2. Locate the Java plugin library file in the installed JDK/JRE
The java plugin file will be - $JRE_HOME/jre/plugin/i386/ns7/libjavaplugin_oji.so
abhi@abhiltlnx(~)$ type java
java is hashed (/usr/bin/java)
abhi@abhiltlnx(~)$ ls -ll /usr/bin/java
lrwxrwxrwx 1 root root 30 2008-02-17 06:22 /usr/bin/java -> /opt/java/jdk1.6.0_04/bin/java
abhi@abhiltlnx(~)$ cd /opt/java/jdk1.6.0_04/
abhi@abhiltlnx(/opt/java/jdk1.6.0_04)$ ls -lth jre/plugin/i386/ns7/
total 140K
-rwxr-xr-x 1 root root 134K 2007-12-14 15:04 libjavaplugin_oji.so
abhi@abhiltlnx(/opt/java/jdk1.6.0_04)$
3. Create a soft/symbolic link to the java plugin file in the firefox plugins folder.
Note: root access needed... use sudo.
abhi@abhiltlnx(/opt/java/jdk1.6.0_04)$ sudo ln -s jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/firefox/plugins/
root's password:
abhi@abhiltlnx(/opt/java/jdk1.6.0_04)$ ls -lth /usr/lib/firefox/plugins/
total 28K
lrwxrwxrwx 1 root root 62 2008-02-26 00:54 libjavaplugin_oji.so -> /opt/java/jdk1.6.0_04/jre/plugin/i386/ns7/libjavaplugin_oji.so
-rwxr-xr-x 1 root root 22K 2007-09-25 00:22 libnullplugin.so
abhi@abhiltlnx(/opt/java/jdk1.6.0_04)$
Exit and restart firefox. You should be able to view the applet on the page.
If you have any issues, make sure that Java has been enabled in the content tab of the firefox preferences dialog (Edit -> Preferences -> Content)
4. View Java Console
In order to view any System.out or System.err messages from the applet, configure the Java Control Panel
abhi@abhiltlnx(/opt/java/jdk1.6.0_04/bin)$ javaws -viewer &
[1] 14233
abhi@abhiltlnx(/opt/java/jdk1.6.0_04/bin)$
Restart firefox and now when an applet gets executed, you'll view the Java Console with all the messages.

HotSpot JVM Options
There are a number of parameters/options you can provide while creating a Java HotSpot VM. The options fall under the following 3 categories:
-
Standard - To list out the standard options do: java -help
abhi@abhiltlnx(~)# java -help Usage: java [-options] class [args...] (to execute a class) or java [-options] -jar jarfile [args...] (to execute a jar file) where options include: -d32 use a 32-bit data model if available -d64 use a 64-bit data model if available -client to select the "client" VM -server to select the "server" VM -hotspot is a synonym for the "client" VM [deprecated] The default VM is client. -cp-classpath A : separated list of directories, JAR archives, and ZIP archives to search for class files. -D = set a system property -verbose[:class|gc|jni] enable verbose output -version print product version and exit -version: require the specified version to run -showversion print product version and continue -jre-restrict-search | -jre-no-restrict-search include/exclude user private JREs in the version search -? -help print this help message -X print help on non-standard options -ea[: ...|: ] -enableassertions[: ...|: ] enable assertions -da[: ...|: ] -disableassertions[: ...|: ] disable assertions -esa | -enablesystemassertions enable system assertions -dsa | -disablesystemassertions disable system assertions -agentlib: [= ] load native agent library , e.g. -agentlib:hprof see also, -agentlib:jdwp=help and -agentlib:hprof=help -agentpath: [= ] load native agent library by full pathname -javaagent: [= ] load Java programming language agent, see java.lang.instrument -splash: show splash screen with specified image -
Non-Standard - To list them out do: java -X
abhi@abhiltlnx(~)# java -X -Xmixed mixed mode execution (default) -Xint interpreted mode execution only -Xbootclasspath:set search path for bootstrap classes and resources -Xbootclasspath/a: append to end of bootstrap class path -Xbootclasspath/p: prepend in front of bootstrap class path -Xnoclassgc disable class garbage collection -Xincgc enable incremental garbage collection -Xloggc: log GC status to a file with time stamps -Xbatch disable background compilation -Xms set initial Java heap size -Xmx set maximum Java heap size -Xss set java thread stack size -Xprof output cpu profiling data -Xfuture enable strictest checks, anticipating future default -Xrs reduce use of OS signals by Java/VM (see documentation) -Xcheck:jni perform additional checks for JNI functions -Xshare:off do not attempt to use shared class data -Xshare:auto use shared class data if possible (default) -Xshare:on require using shared class data, otherwise fail. The -X options are non-standard and subject to change without notice. -
Hidden - Well as the name suggests, they are hidden. These options typically have a -XX prefix

Using VirtualBox - Ubuntu 7.04 on openSUSE 10.3
My first shot at OS virtualization was almost a year back when I dabbled with
VMWare to run Solaris on my Windows XP. When I read about Sun's acquisition of innotek - makers of
VirtualBox, I decided to check it out.
So I downloaded the latest RPM of VirtualBox for
openSUSE 10.3 and installed it on my system. The installation was very simple and
within minutes I was able to install Ubuntu 7.04 as a guest OS on my openSUSE.

NetBeans 6 and Java 6 on openSUSE 10.3
I've been struggling to install NetBeans 6 on my openSUSE 10.3. The installer would startup alright but would crash soon after displaying the bug-buddy dialog. After few attempts, I ran the installer using Java 5. This time the installer gave the following error:
java: xcb_xlib.c:52: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
After googling the above I found the following bug - http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6532373. I also found the workaround on the same page i.e. set the following environment variable:
export LIBXCB_ALLOW_SLOPPY_LOCK=1
After implementing the workaround, I was able to install NetBeans and run it. However, once I upgraded my JDK to Java 6 update 4, and executed NetBeans, the splash screen would appear for a brief moment and then it would crash displaying the bug-buddy dialog.

I tried uninstalling/installing Jdk6u4 a number of times - manually, RPMs, YaST etc. to no avail. Since I was unable to understand the bug report, I decided to uninstall bug-buddy in the hope of getting more meaningful information on the terminal. The moment I unistalled bug-buddy, I was able to run NetBeans using Java 6.
root@abhiltlnx(~)# zypper rm bug-buddy

The following package is going to be REMOVED:
bug-buddy
After the operation, 2.0 M will be freed.
Continue? [yes/no]: yes

As it turned out bug-buddy wasn't much of a buddy in this case.

Installing openSolaris (SXDE 1/08) and openSUSE 10.3
After almost a year I decided to upgrade the Operating Systems on my laptop. The plan was to install the latest Solaris build - Solaris Express Developer Edition 1/08 (snv_79) and openSUSE 10.3 along with the pre-installed Windows XP. I managed to get hold of a USB hard disk to take a backup of my data, partitioned/formatted my disk and installed Win XP.

Embedding images in OpenOffice text documents
Whenever I copy and paste some content (text with images) from a web page into a OpenOffice text file (.odt), I notice that the OpenOffice writer application doesn't respond for few seconds. I understand that it takes time to fetch/load/render the images that are part of the copied content in the document and it's the same with other office applications like MS Word.
But what I find really frustrating is that having done so (copy+paste+save), it still tries to access the images online everytime I scroll through the document. As a result of which the OpenOffice writer application becomes slow and does not respond for few seconds. Moreover, the images don't get displayed and I get a "Read-Error", if I open the document when I'm not connected to the Internet.
The problem in the above case is that OpenOffice stores only the "link" to the online image and not the image itself. So everytime you open the document, the text content gets loaded and the application tries to access the image resource online.
(Select an image, right-click and select Picture to see the link details.)
Now, this is bound to put off any avid MS Word user as the behaviour they are used to is that images get embedded as part of the document itself.
Well after hours of tweaking here and there, I found out that OpenOffice actually allows both linking as well as embedding images in a text document, the former being the default behaviour. So, if you have a document that works with images as links to online resources and you would like to embed them instead, just do the following:
(Go to the menubar and select Edit -> Links)
The "Edit Links" Dialog gets displayed that shows all the links (mostly images/graphics) in the current document.
Now select the links to the images you want to embed and click the "Break Link" button.
To check if the images are embedded parts of the document and not links.
(Select an image, right-click and select Picture)

FAT32 filenames in Linux
I have a multi-boot machine with Solaris, Linux & Windows installed. So my hard disk currently has all different sorts of filesystems.
root@lnx(~)# fdisk -l
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 1912 15358108+ 7 HPFS/NTFS
/dev/sda2 4086 8682 36925402+ f W95 Ext'd (LBA)
/dev/sda3 1913 4080 17414460 bf Solaris
/dev/sda4 * 8683 9729 8410027+ 83 Linux
/dev/sda5 4086 6635 20482843+ b W95 FAT32
/dev/sda6 6636 8420 14337981 b W95 FAT32
/dev/sda7 8421 8682 2104483+ 82 Linux swap / Solaris
When using Linux, I've been struggling to work with any NetBeans web application projects that were stored in my FAT32 partitions. Upon opening a web project, NetBeans would complain that WEB-INF folder is missing.
After a quick ls -l, I noticed that the WEB-INF folder appears as web-inf i.e. in lowercase.
Well the reason behind this anomaly was the way the Windows FAT32 partitons were mounted on my system.
root@lnx(~)# vi /etc/fstab
. . .
/dev/sda5 /mnt/win_d/ vfat users,gid=users,umask=0002,utf8=true 0 0
/dev/sda6 /mnt/win_e/ vfat users,gid=users,umask=0002,utf8=true 0 0
. . .
So I remounted the FAT32 partitions with the option shortname=mixed and everything became fine.
root@lnx(~)# umount /mnt/win_d/
root@lnx(~)# umount /mnt/win_e/
root@lnx(~)# vi /etc/fstab
. . .
/dev/sda5 /mnt/win_d/ vfat users,gid=users,umask=0002,utf8=true,shortname=mixed 0 0
/dev/sda6 /mnt/win_e/ vfat users,gid=users,umask=0002,utf8=true,shortname=mixed 0 0
. . .
root@lnx(~)# mount -a
The WEB-INF folder now appears as it is (i.e. in uppercase).
The default behaviour of a FAT32 mount uses shortname=lower, so any file/folder with a shortname i.e. less than 8 chars (excluding file extension) would appear in lowercase.

gnomesu dialog problem
For the last few days, I have been unable to invoke yast by clicking on the launcher icon 
. I soon realised that it held true for every applet that required root access for execution. Earlier, when I used to click on these launchers, the username/password window/dialog box would appear and if the user entered the correct password, the applet window ( yast2 in this case) would appear.
I've been too occupied with work offlate to look into this aberration. I stopped using the launchers and would directly invoke the applet from the terminal:
root@lnx:~ # yast2 &
Today I decided to look into the matter and found out that the cause of the problem was the username/password window/dialog box applet. I did some search online to find out its package name. The dialog applet is gnomesu and is part of the libgnomesu package. I tried invoking gnomesu from the terminal but got the following output:
root@lnx:~ # gnomesu
** (gnomesu:6922): CRITICAL **: No services for libgnomesu are available.
I decided to re-install/update libgnomesu to see if the problem still persists. I invoked yast2 from the command line and updated libgnomesu. Once installed, gnomesu worked fine. Now I'm able to invoke application requiring root access by clicking on the launcher icons.

Swing problem on Xgl and openSUSE/Linux
I installed NetBeans 5.5 on openSUSE 10.2 and found out that Swing applications are not rendered properly. The installer dialog itself appeared like an icon and I had to resize it. The IDE itself was either appearing as an icon or it would scale past the screen size. The "New Project" dialog (or any window/dialog for that matter) also displayed the same behaviour and were not appearing in the centre of the IDE. I created a simple swing GUI application and realized that the JOptionPane message dialog was also not appearing in the center. I checked if I was using a very old JDK and found that my default JDK was - Java 6 build 105.
Many hours later (sigh) I found out that Swing applications have rendering issues with Xgl.
Bug ID - 6429775: Xgl/Compiz/Java 1.5/Swing problem
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6429775
Everything worked fine once I disabled XGL. But having got used to the cool way of working using Xgl I just couldn't keep it disabled for long. Fortunately, this bug seems to have been fixed in Java 6 update 1. So I downloaded it and everything worked like a charm.

openSUSE 10.2 and Xgl
Last week I installed openSUSE 10.2 on my laptop and I'm very impressed with this linux distro. I have been planning to install linux on my laptop (along with Windows and Solaris) so that I could check the user experience of a Swing application project that I've been involved with.
I have been using Red Hat/Fedora for few years now but the recent buzz around other linux distros viz. Ubuntu, openSUSE, Mandriva etc. piqued my interest to try them out. The difficult part in a linux installation is deciding which linux to install. I discussed with few friends of mine - each one recommending the one they use. I did some reading on the web.. distrowatch is a very good resource. Finally I zeroed on openSUSE 10.2 .
The installation was very smooth.. a bit time consuming though. I really liked the admin/setup tool - yast (Yet Another Setup Tool).
openSUSE provides most of the applications one needs out of the box.
- OpenOffice for office applications
- Firefox as browser
- Evolution as email client (which I replaced with Mozilla Thunderbird)
- Gimp for graphics
- Real Player and Totem for playing movies. I prefer VLC media player, so I installed it later.
- Helix Banshee for playing MP3s and syncing with IPod. It's an excellent player although I'm struggling with the iPod syncing part due to the iPod Raid bug. Will look for the openSUSE fix later.
Configured Compiz/Xgl for the jazzy stuff 
openSUSE has a very active community presence and have good documentation online viz. articles, blogs etc. Getting XGL to run required installing NVIDIA drivers and some tweaks here and there. I found the following resources very useful:

Xgl Troubleshooting - http://en.opensuse.org/Xgl_Troubleshooting
