Give them a rest ...

[Misterfixit]

It's obvious by now that both the pro and regular version of LimeWire for Linux is suffering from some very serious problems.

I got a call yesterday from a tech guy after I had posted several times in the sticky forum. Also, I have e-mailed directly to another tech guy for advice. The one guy said he had to get a person "familiar with Linux" to look at my output. Meanwhile I got an explanation.

Basically, if I understand the situation correctly, there is something in the way SELinux and Fedora Core 3 reacts with some scripts in LimeWire.

For example, when java is installed in any folder other than where the LimeWIre script expects it to be, there is a fault which says, java isn't there. Then the install script searchs and if it is present in another directory, finds java and tries to use it. There is a permissions problem there, evidently.

Next, the issue of having to open a super user terminal window and type "limewire" to start the GUI LimeWire has something to do with the SELinux configuration. For example, before I got LimeWire Pro and completely hosed my system, I could actually start two LimeWIre episodes at the same time (naturally). One by opening a superuser terminal and running LimeWire as root and then going to a non-su terminal and running another LimeWire as user. Both settings were different, of course. We don't want to be running LimeWire as root in my opinion under any circumstances.

Wiping the system clean of all LimeWIre and all Java is also problematic. There seems to be code or scripts left behind (just like Windows and those unused dll's and other registry orphans) which tell the new installation that there is already an installation present. None of the usual "use rpm to remove" stuff works, since the LimeWire package evidently sends off scripts which are no longer identifiable as part of the rpm package to be removed using the rpm removal routine. Even doing a find for anything with the "java" and "limewire" in it and then deleting all of those items didn't work.

By the way, when I ran the free LimeWIre as root it worked perfectly the first time except for periodic crashes due to java exceptions.

Tomorrow I am going to build a Fedora _2_ box as a test bed. I will limit the installation to a basic KDE FC2 box. I will d/l java and install and then d/l the free LimeWire and install .. both going exactly as the directions state.

I'll report back here if that is a success.

My expectation is that when LimeWIre is installed there should be either an icon on the desktop or a line in the "applications" popup just like there is when kaffeine is installed, for example.

Meanwhile I think we ought to give the LimeWire techies a rest and not keep posting that our LimeWire Pro fails to work. We all know it doesn't work, so we just have to sit back and let them fix it. They evidently are working overtime trying to fix this problem for us Linux people and we should give them credit for that.

OK, I finished the FC2 project:

I took an old Dell box with a 80GB HD and 1.2 Ghz processor, 1GB of RAM and low level formatted the hard drive (yes, I do know what "low level formatting means, so don't ask if I "really did that")

I used a set of Fedora Core 2 CD's which I downloaded and burned some time ago to boot up and install to the machine as a single boot, Fedora Core 2 box.

I used the "minimum installation" option and selected KDE as the X GUI.

I went to the Sun web site and downloaded the Java Run Environment (JRE) package which is named: "J2SE v 1.4.2_08 JRE includes the JVM technology" from the Sun web site
( http://java.sun.com/j2se/1.4.2/download.html )

I used the rpm installer to install the JRE and after installation I used a user terminal to do the check. Java installed correctly.

Then I went to the Limewire web site and downloaded the LimeWire free edition from
http://www.limewire.com/english/cont...loadfree.shtml

Using the rpm installer again, LimeWIre was installed.

I went to the desktop gui and looked for either in icon or a LimeWire command in the pop=up menu. I found LimeWire in the area labeled "Internet"

I clicked on that line and LimeWire's gui began on screen and opened the application.

I configured my personal preferences and immediately began downloading successfully.

I placed the CD with LimeWIrePro in it and installed using the rpm installer and it installed over the existing fre LimeWire.

LimeWIre Pro now works as well.

This test proves to me that the LimeWire installation for Fedora Core 3 with SELinux is hosed.

OK, I am back on my FC3 box while my FC2 box is downloading mucho pron ;-)

Stay with me now and we will see how this works out.

First, here is the failure output from the attempt to run LimeWIre under FC3 as user "dave":

Something went wrong with LimeWire.
Maybe you're using the wrong version of Java?

Notice that the error message is (of course) the same as contained in the script's instructions.

Next: I try to find out exactly where in the script, runLime.sh did the fault occur.

Understand that I am an old Cobol programmer from the 1960's and 70's who wrote applications in job control language and some Pascal apps. So, some of my conclusions may seem st00p!D to the Real Nerds out there reading this.

Here is the smoking gun:

Warning: -jar not understood. Ignoring.
Exception in thread "main" java.lang.NoClassDefFoundError: LimeWire.jar

A search rendered this anwer to the error line Exception in thread "main" java.lang.NoClassDefFoundError

"Probably a failure to find the correct path". With this instruction:

Set the PATH environment variable: (/etc/profile or .bashrc).

PATH="$PATH:/usr/java/j2sdk1.4.2_03/bin:."
export PATH

Go here for further infos:

Next, I went ahead and did the PATH command:

[root@localhost dave]# PATH="$PATH:/usr/java/jre1.5.0_04/bin:."
[root@localhost dave]# export PATH

The same error message was received after commanding limewire.

Next I went to some more forums and found that this is a very common error with no quick answers that I could find:

Look here for an example:

So much for right now. I will continue the investigation after I get through with doing a BBQ of some bratwursts, drinking some beer and generally chilling out this afternoon.

Get the beta version. It fixed some problems with the run script.
