<h1><a name="DebuggingOSGiproblems-DebuggingOSGiresolverproblems"></a>Debugging
OSGi resolver problems</h1>
<p>To diagnose OSGi resolver problems it might be useful to turn on OSGi framework's
debug level. Apache Felix and Eclipse Equinox have different way to enable and configure the
debug options:</p>
<h2><a name="DebuggingOSGiproblems-Felix"></a>Felix</h2>
<p>To turn on debugging when running with Apache Felix edit the <tt>etc/system.properties</tt>
file and uncomment the following line:</p>
<div class="code panel" style="border-width: 1px;"><div class="codeHeader panelHeader"
style="border-bottom-width: 1px;"><b>etc/system.properties</b></div><div
class="codeContent panelContent">
<pre class="code-java">
felix.log.level=4
</pre>
</div></div>
<p>The <tt>felix.log.level</tt> property can be set to any value between
0 and 4. 4 means maximum log level.</p>
<h2><a name="DebuggingOSGiproblems-Equinox"></a>Equinox</h2>
<p>To turn on debugging when running with Eclipse Equinox edit the <tt>etc/system.properties</tt>
file and uncomment the following line:</p>
<div class="code panel" style="border-width: 1px;"><div class="codeHeader panelHeader"
style="border-bottom-width: 1px;"><b>etc/system.properties</b></div><div
class="codeContent panelContent">
<pre class="code-java">
osgi.debug=${karaf.home}/etc/equinox-debug.properties
</pre>
</div></div>
<p>The <tt>osgi.debug</tt> property specifies a Equinox property file which
contains a number of options for controlling the amount and type of logging generated by the
Equinox framework.</p>
<h3><a name="DebuggingOSGiproblems-Using%7B%7Bequinox%3Adiagnose%7D%7Dcommand"></a>Using
<tt>equinox:diagnose</tt> command</h3>
<p>On Equinox it might also be possible to diagnose some resolver problems using the
<tt>equinox:diagnose</tt> Geronimo shell command. Example:</p>
<div class="code panel" style="border-width: 1px;"><div class="codeHeader panelHeader"
style="border-bottom-width: 1px;"><b>Geronimo Shell</b></div><div
class="codeContent panelContent">
<pre class="code-java">
