.bash_profile?

Im a newbie.....

where is this and how do i find it?

Thank you. Your problem and solution are both well appreciated. I had came across that solution a long time ago but I had never came across a situation where I needed it implemented. I will add that to the installation guide that I haven't regrettably finished yet. I have a new problem that as far as I have seen on this list, no one has come across it yet. Once, I solve that installation issue, I will indeed have THE ultimate installation and troubleshooting guide.

it is in your home directory of your user.

(example:

suppose your user login name is yesm

/home/yesm/.bash_profile)

If you don't have .bash_profile .bashrc is a good substitute.

any file with a "." (period) before the name of the file or directory means that it is "hidden". Doing a "ls" or "ls -l" will not find the file. While "ls -a" or "ls -a .bash*" will!

Add me to the list of Linux LimeWire "L-users"

I have read all the threads in this session and have followed the instructions, but to date I still haven't seen any improvement in the install. In short, LimeWire still cannnot find the PATH to my Java virtual machine.

Here are my specs:
I have this installation path for my java:
/usr/java/j2re1.4.0_01

I have created a symbolic link to:
/usr/bin/java
with this server path:
/usr/lib/j2re1.4.0_01/bin/.java_wrapper

The symbolic link was created, so the directory path seems to be valid.

I have edited my .bash_profile to read:
export Java_HOME=/usr/java/j2re1.4.0._01
export PATH=$JAVA_HOME/bin:$PATH

After making these updates, I log out as root and then type:
sh ./LimeWireLinux.bin and receive the missing virtual path error.

So, I'm not sure how to proceed from here. Any clues?

That depends... the link can be broken as it should be in your case. You only need to create a link to /usr/bin/java with .java_wrapper ONLY if it is a jvm from www.blackdown.org.
Your version seems to be a different sort. under your java bin directory should be a java, javac, etc that you can link to the /usr/bin directory :

ln -s /usr/lib/j2re1.4.0/bin/java /usr/bin/java

and

ln -s /usr/lib/j2re1.4.0/bin/javac /usr/bin/javac


I have edited my .bash_profile to read:
export Java_HOME=/usr/java/j2re1.4.0._01
export PATH=$JAVA_HOME/bin:$PATH
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
All wrong above. Close but not for *nix useage. It should read:

export JAVA_HOME=/usr/lib/j2re1.4.0
export PATH=$JAVA_HOME/bin:$PATH

or

export JAVA_HOME=/usr/lib/j2re1.4.0_01
export PATH=$JAVA_HOME/bin:$PATH

depending on the actual path to your jvm directory. You have it listed as /usr/lib/j2re1.4.0 in one instance and then have the path listed as j2re1.4.0_01 in another. Everything is predominately case sensitive in *nix (linux, unix, freebsd, etc).
This should fix your problem and I will update/upload the Installation Instructions on how to install using any environment and any jvm from virtually any source. My apologies for not doing this sooner but I was away for a few weeks. Deep in rebuilding my own projects from the ground up.

I have Redhat 7.3 with j2re-1.4.1-beta i did everything exactly like it was told, and I still get the:
""Preparing to install...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...
No Java virtual machine could be found from your PATH
environment variable. You must install a VM prior to
running this program. "" error message what do I do?


Thanks in Advance,

export JAVA_HOME=/usr/java/j2re1.4.0_01
export PATH=$JAVA_HOME/bin:$PATH

Is /usr/java/j2re1.4.0_01 really the path to your java version?

To test type:

which java

Do you get any output?
If you get output, that should be what goes after JAVA_HOME.
In the second export command (PATH), is JAVA_HOME referenced as #JAVA_HOME or JAVA_HOME as the $, dollar sign, is needed in the second export line not the first.
In the second line, is $JAVA_HOME/bin followed directly by $PATH with no :, colon, or is it followed with a :, colon ($JAVA_HOME/bin:$PATH)?
It needs to be followed by a :, colon.

Did you make sure that when you exported JAVA_HOME, you made sure the cases matched? (As it is case sensitive --for the newbies)

I postulate that one of the above questions will answer and solve your problem.

after doing that which java i get this:


[root@dhcp-58-42 Downloads]# which java
/usr/bin/which: no java in (/usr/local/sbin:/sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin:/usr/local/bin:/root/bin)

so now what?

thanks in advance,
SED

i reinstalled RH 7.3 cuz I had a prob with my video card, I also installed j2re 1.4 this time instead of j2re 1.4 beta, and another thing, I'm doing all of this in 'root' could that be the problem? Sorry I'm a Super Newbie =)


thanks -SED

The export command wasn't working prolly cuz I was doing it wrong, so I did a 'vi' command on the .bash_profile and tried to edit it that way but I didn't know any of the commands, so I opened the .bash_profile in 'KATE' (advanced text editor) anyways I added the export commands under the other export command that was already there, and saved it logged in and out did a 'which java' command and bodda bing bodda boom it was there, I also did a 'java -version' command and that also worked too, so I was very delighted, so I did the 'sh' command on the LimeWireLinux.bin and it installed it with some errors that didn't seem to effect the installation process... hmmm.. ok so just wanted you to stop boggling your minds thanks for the help =)

Congratulations! No boggle at all as I told you the problem was more likely a typo which apparently it was. There is no way you can enter the export command correctly and not be able to do "which java" or "java -version". I thank you for opening me to another level of newbie instruction. I see I will have to explain all the way to the detail of what editor and with how to save and exit. Thank you once again and congratulations. If the second line of the "export JAVA_HOME" in your ".bash_profile is correct, you can remove the line above it as it is wasting space.

Thanks!

This worked. The solution needs to be posted on the Limewire website.

Thanks for the install help. This guide also allowed me to install java completely which my RedHat 7.3 won't allow.

The instructions as far as using $JAVA_HOME in your .bash_profile or .bashrc has been what had to be done for all java installed on unix but it isn't in the installer to do this. Probably because some admins limit what shells their users can use and sometimes will disable bash outright. When using a different shell like ksh (Korn shell), your export command is different. An entirely different syntax. I was going to create instructions for the other shells, but it appears no one has had any situations with an account with the restriction to use bash (Bourne Again shell). I have a script to do all the installing using LimeWire's tarball or installer with specific java packages. I want it to be able to use any java installer and thus I will have to get back to my little script one day and revise it with the necessary changes to bring that capability to fruition.
