Software :: Build A RPM That Requires JAVA_HOME To Be Set Before Install?
Nov 6, 2009
I've managed to create a working RPM that does a bit of system configuration despite having little working knowledge of linux before starting. My RPM appeared to be working for awhile now but as a final test I installed it on a completely fresh install of RedHat enterprise edition 5.2 (after installing prereq rpms). It seems I'm running into a problem that the IMQ program(ie java message queues) will not boot correctly when I do this because it doesn�t know where to find the JRE.
I want to make sure that when my rpm is run the program actually works afterwards, and it won't work without IMQ. I was thinking I would have the RPM modify the IMQ configuration file to provide a -javahome argument when it boots up. I don't think I can set the configuration file to say '-javahome $JAVA_HOME' because the JAVA_HOME environmental variable won't be set until later in the boot up process after IMQ has attempted, and failed, to boot.
so I had thought the rpm could set whatever the value of JAVA_HOME is at the time the rpm is installed as the home for IMQ. So my questions are...
1) how can I require that JAVA_HOME is set prior to running my RPM, and have the RPM not install if JAVA_HOME isn't set
2) is there a good way to have rpm be able to undo the change I made to the configuration file if it is erased? Should I save a version of the old configuration file before I make the changes somewhere to be used?
3) is this the best way to do things, or is there a simpler method?

Trying to install SW 13.1 (on DVD) on the following system: M/B Intel: DX38BT Processor Intel Core 2 Quad Q6700 - 2.66GHz, 8MB Cache, 1066MHz FSB, Socket 775 Memory Corsair Dual Channel 8192MB PC10600 DDR3 1333MHz Memory (4x2048MB) Graphics Diamond Radeon HD 3850 Video Card - Viper, 512MB GDDR3, PCI Express 2.0 P/S Ultra 1000W
My goal is to install the i386 build on one partition and the 64-bit build on another. I have been away from Linux for a while and am sick to death of Win7, want to come home. :-}
Booted on i386 side of DVD, system freezes after a couple of lines that start with ATA2. Does not respond to 3 finger salute, ctrl-c, nothing. Have to press reset. I have tried both huge.s and hugesmp.s kernels
Booted on 64-bit side, comes up fine. I performed the install, selected for automatic lilo install. Lilo install hung but I was able to reboot. I booted off the 64-bit side again, entered the following: huge.s root=/dev/sde3 rdinit= ro It booted fully to the login prompt but the keyboard does not work, no input.

'm running openSUSE 11.2 with KDE 4.4.2.
Since i installed KDE 4.* Whenever I go to shutdown, I get the shutdown dialogue, I hit shutdown, it logs me off, shows some text on shutdown screen, and then opens up the GUI again, bringing up a small window, where It asks for the root password, in order to shutdown. If i don't give it the root password, it goes to the login screen.
I cannot, any way, command line, GUI, or anything, shutdown without providing a root password.
If I use the command shutdown now, as root, it logs me off and goes through an endless cycle of logging off, and then asking for root to shut down, and not shutting down (All on the CLI), and everytime i give it the password, it cancels shutdown and goes back to the prompt. I eventually have to pull the battery to kill it in that case..
I have tried chmoding the shutdown scripts to make it work, it doesn't.

There is a "standalone seamonkey-solibs package for RPM, gxine, etc". But after recent upgrades in -current, I can't use rpm without full seamonkey package installed. Can someone revise the contents of seamonkey-solibs and add missing files to it?
$ LANG=C rpm -qp --qf %{NAME} opera-11.00-1156.i386.rpm
error: opera-11.00-1156.i386.rpm: Header SHA1 digest: BAD
error: opera-11.00-1156.i386.rpm: not an rpm package (or package manifest)
And `rpm2txz -nd opera-11.00-1156.i386.rpm` doesn't work as expected without seamonkey package installed.

Im running opensuse 11.2 on Linux 2.6.31.5-0.1 64Bit, KDE 4.3.1 with 4GB RAM, Intel duo core processor with Intel graphics card. I initially had opensuse 11.1, which i removed and installed 11.2. Initially everything.Then came the problem, the system starts up fine but then after a few hours freezes, monitor powers off and it wont accept commands from the keyboard or mouse. Meanwhile the lights (caps lock, numeric and scroll) on the keyboard blink. The power light is still on and i can hear the hard disk turning.
I have to forcefully turn the power off and restart but can freeze again after random periods.I do lengthy and demanding computations and its common for the PC to run for weeks without turning it off.

When booting from the Ubuntu 11.04 CD, it asks for user name and password to install. I downloaded the iso twice and did a checksum. Do I need a user name and password before installing? What is the user name and password? I read the documentation and cannot find any entry about user name and password needed when booting fron CD.

I am trying to install a piece of software that requires a specific versions of several packages. I am using Scientific Linux 5.5 and yum for managing the apps.The problem is that I need, for example ruby >= 1.8.7, but the package for ruby that is the official repositories for SL 5.5 is 1.8.5 and therefore yum says it's up to date.
There are other repositories for SL 6.0 that have ruby-1.8.7. Initially I ignored the fact that they are not for 5.5 and tried to install it manually with rpm. But there was an increasing number of data dependencies for the packages so I gave up. What can I do to avoid this? I suppose installing packages for newer OS version should be ok and they will be compatible with other older libs. But do you really install packages in this manner?

You can install Java either using "Synaptic Package Manager" or using "apt-get install java-6-openjdk" command.Java will be installed to the location "/usr/lib/jvm/java-6-openjdk"Now open a terminal and type "sudo gedit /etc/bash.bashrc ".Append the following lines to the opened "bash.bashrc" file
"export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/"
"export PATH=$PATH:$JAVA_HOME/bin"
Save & close the "bash.bashrc" file
[code]....

Tomcat installation requires JAVA_HOME to be defined. In Windows it is straight forward. But in Linux binaries are in one folder and libraries are in other folder.
Is there a way to find out where exactly is JAVA_HOME?

I have problems with setting my JAVA_HOME variable. I am using Slackware 12.0, bash shell. I have set JAVA_HOME in my /etc/profile, like this:
But when I login in with my user name and type env on the command line, I get for JAVA_HOME the following:
Also, in my /etc/profile I have put the path to my java in the PATH variable, like this:
And when I type env when I login, then the PATH variable contains correctly the path to the jdk (as I have put it into /etc/profile).
I expect that after I have set everything as I want in /etc/profile, and restart the computer then what I have set will be relevant and when I login and type env, I will get values to the variables equal to those I have set in /etc/profile. Why it does not happen?
I have particularly a problem with a Java application, which I want to run. When I type ant, I get: error: JAVA_HOME is not defined correctly.
We cannot execute /usr/lib/java/bin/java.

I have some Flex and Java files which can be compiled with JDK1.5. My server was already loaded with 1.4 (at path /usr/bin/java) and our sys admin(I dont know why) copied another JDK, JDK 1.5 at path /usr/java/jdk1.5.0_16/. It seems very easy to use this java. Just set the path in .bash_profile. I did it and now if I run which java I still see the path for java 1.4 not java 1.5. Am I doing something wrong? Following is actual entry from bash_profile
Code:
PATH=$PATH:$HOME/bin
PATH=/usr/java/jdk1.5.0_16/bin:$PATH
JAVA_HOME=/usr/java/jdk1.5.0_16/
export PATH JAVA_HOME
