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 want to test whether or not my phone is connected from bash. I'm finding lots of information about /dev/rfcomm0, but that's not on my system (Ubuntu 10.04). The device pairs just fine, and I can connect with gammu just fine, and I have the device address ("00:1F:5D:37:17:FB").I just need something I can put in a bash script to say "Is this connected or not" akin to testing for a file's existence:
Code:
if [ -f /home/steven/arbitrary filename ]

View 2 Replies View RelatedI am fairly new to bash scripting, and I am trying to test a variable against a number range (1-3). This is what I have used so far: The user enters a value, then
while [ "$PROV" != "1" ] && [ "$PROV" != "2" ] && [ "$PROV" != "3" ] && [ $COUNTER -lt 4 ] || [ -z "$PROV" ] && [ $COUNTER -lt 4 ]; do
clear
echo

Is there a cleaner way to do this? Something like:
while [ "$PROV" != "1-3" ]&& [ $COUNTER -lt 4 ] || [ -z "$PROV" ] && [ $COUNTER -lt 4 ]; do
I have a directory with files like this:

How could I code it so that it removes the numerical part of the filename (at the beginning), even with different patterns (like the 01 - artist vs the 01-artist)?
I have installed jdk1.60_23 i have created a directory named java in root's Home, jdk has installed in jdk1.60_23 directory in java how to set path to compile or run the java file ?
I did like this : export JAVA_HOME=/usr/bin/java/jdk1.60_23/bin export PATH=$JAVA_HOME:/usr/bin/java/jdk1.60_23/bin
How check the path has properly set or not ? how and where create source file of java ? how to compile and run the java source file ?
Where to write JAVA_HOME? In .bashrc or in .bash_profile? What's the difference?
View 1 Replies View RelatedI have some Flex and Java files which can be compiled with JDK1.5. My server was already loaded with 1.4 (at path /usr/bin/java) and our sys admin(I dont know why) copied another JDK, JDK 1.5 at path /usr/java/jdk1.5.0_16/. It seems very easy to use this java. Just set the path in .bash_profile. I did it and now if I run which java I still see the path for java 1.4 not java 1.5. Am I doing something wrong? Following is actual entry from bash_profile
Code:
PATH=$PATH:$HOME/bin
PATH=/usr/java/jdk1.5.0_16/bin:$PATH
JAVA_HOME=/usr/java/jdk1.5.0_16/
export PATH JAVA_HOME
I installed "jdk1.6.0.bin" and "jre1.6.0.bin" successfully. But I don't know where they are installed. I can't find anywhere. What is the default path they are installed.I want to set JAVA_HOME.
View 1 Replies View RelatedI look after a server which accepts automatic overnight PASV FTP uploads from remote clients. When the uploads are complete, my Bash script copies the files to another location. The problem is, my script needs to be a bit smarter when it comes to detecting active FTP sessions.
I was using:
Code:
netstat -n | grep ":21 " | grep ESTABLISHED
to test if there were active sessions, but came unstuck when a local user left an unrelated FTP session active. The result - my script hung around all night thinking there was an active upload from a remote client. My server is behind a firewall, so remote clients all show an internal (NAT) address,so I can't differentiate by source IP address.I can't install LSOF or FUSER for security reasons. Is there a way I can test for active FTP sessions from specific users? I am running Red Hat Enterprise Linux Server release 5.2 (Tikanga).
Here the description of the issue I am having.I am writing a bash test script which reads lines from a file, builds ISO messages, sends them to a server, reads the response with response code and reports the result of the test to a file or on the screen.The message that I need to send is 94 characters long.Here's the portion of a code that I initially wrote:
#~ Open socket.
exec 3<>/dev/tcp/172.26.0.25/9991
#~ Send msg.

You can try to start the mysqld daemon with:

and use the command line tool /home/mosty/mysql/bin/mysql to connect to the mysql database and look at the grant tables:

mysql> show tables

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?

I installed openjdk version of Java using yum what is the openjdk Home directory?
Is there a command to find it?
/usr/lib/jvm/java-6-sun-1.6.0.20/bin
Code:
Have the default entries no changes with them.
Code:
Code:
When I run mvn get error
Code:
Error: JAVA_HOME is not defined correctly.
We cannot execute /usr/lib/jvm/java-6-sun-1.6.0.20/bin/bin/java I am not having any clue as what is this error? As to me JAVA_HOME seems to be defined.
I've been following the instructions to install Resin, and all seems to go well until I try to run the /bin/httpd.sh file. It simple says:
Code:
exec: 40: -jar: not found
I suspected this was something to do with my JAVA_HOME variable not being set, so I looked up how to do this and added it to my /etc/bash.bashrc file. Saying "echo $JAVA_HOME" does indeed return the correct path so I don't think this is the problem.
