        <title>Only one window when I run reprap-host</title>
        <description> I run reprap-host with win XP and win Vista and Java sun 6. With both, when I run reprap-host V9 or V8, only one window is opening.

Is it because I haven&#039;t connect an Arduino ?

Here are errors :

Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
Exception in thread &quot;RepRap&quot; java.lang.NullPointerException

            <description><![CDATA[ In my impatientence I decided to find a way around this problem since I have no clue how to fix it.  I edited ~/projects/reprap/Reprap/src/org/reprap/gui/botConsole/PrintTabFrame.java.  I removed lines 221 and 222 which were:<br />
<br />
<pre class="bbcode">
getWebPage.setIcon(new javax.swing.ImageIcon(
    ClassLoader.getSystemResource("rr-logo-green-url.png"))); // NOI18N</pre>

            <description><![CDATA[ I'm getting the same errors as bernard46, but I can't seem to solve the problem.  I'm trying to get an install from the LiveCD (0.6, I think) to work.  I've checked out the latest from svn and I'm attempting to launch the application using the command "ant run".  Here is the errors:<br />

Any clues where I should put this?]]></description>

            <description><![CDATA[ I am experiencing the same issue with Mac OS X Tiger.   I followed the instructions from the wiki to install rxtx and the other java libraries into the /Libraries/Java/Extention folder.<br />
<br />
AoI launches and runs as expected<br />
<br />
launching reprap.jar only opens one window the viewer window.<br />
<br />
Running the shell scripts produces the same result.<br />

I made a folder <br />

gui/botConsole and moved the png files into it.  Makes no difference.<br />

Do the FTDI drivers need to be installed for the console window to open?  <br />

            <description><![CDATA[ Hello,X(<br />
<br />
Thanks to Sid and to Jonwise because it was a good idea, I have used winjar to add file .jnp at reprap.jar and now 2 windows are openning. But, nothing is perfect never :S, the bot console is not like the doc, I haven't the load buttons (blue, pink grey) and no error in console. I send you copy of this windows.<br />
<br />
But i am not desesperate...]]></description>

            <description><![CDATA[ you're welcome.<br />
<br />
Well I guess jonwise meant to place it in the named folder.<br />
That folder does not exist in the compiled version;<br />
only packed directly to reprap.jar<br />
So either you can try creating such folder<br />
that'd be "\reprap\gui\botConsole\rr-logo-url.png" inside the org folder you already have next to the reprap.jar<br />
<br />
or you can try place that file directly inside the reprap.jar<br />
that'd be "reprap.jar\org\reprap\gui\botConsole\rr-logo-url.png"<br />
you can open and edit jar files with WinRar for example,<br />
don't know if it works afterwards though, so keep a backup handy ;)<br />
<br />
And yes, I doubt that this will solve your errors, but I cannot tell for sure.<br />
So it wont harm to try :D<br />

            <description><![CDATA[ here you are.<br />
<br />
But that file is only necessary for the sourcecode afaik,<br />
it's not packed with any precompiled host yet.<br />
<br />
(not even packed in the jar at reprap.jar\org\reprap\gui\botConsole)<br />
