    copied!<p>So, I'm aware that this might have been asked a lot already, but I really tried what I could and I couldn't fix this. I've been trying this for over two weeks and followed every single tutorial on the Apache Tomcat website, to no avail.</p> <p>So, what do I want? I want to deploy Java webservices to my server. I've got Apache httpd and tomcat running. So when I've got my webservice, I build and clean it and I copy the <code>.war</code> file to my tomcat <code>tomcat_home\webapps</code> folder.</p> <p>I've got the <code>mod_jk</code> module installed and loaded into Apache httpd (actually apache2), and then I've got these settings:</p> <p>Apache config (<code>/etc/apache2/apache2.conf</code>):</p> <pre><code># Tomcat LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so # jk_mod properties JkWorkersFile /var/lib/tomcat7/conf/workers.properties JkLogFile /var/log/apache2/mod_jk.log JkLogLevel error JkLogStampFormat "[%a %b %d %H:%M:%S %Y] " # map requests to these folders to the tomcat worker JkMount /webservices/* apacheworker JkUnMount /*.html apacheworker JkUnMount /*.jpg apacheworker JkUnMount /*.gif apacheworker </code></pre> <p>This probably works, as the apache service restarts without a problem (when I hadn't created the log file yet, apache didn't start anymore).</p> <p>This is my <code>workers.properties</code> file (at <code>/var/lib/tomcat7/conf/workers.properties</code>): </p> <pre><code># the list of workers worker.list=apacheworker # define the workers properties worker.apacheworker.type=ajp13 worker.apacheworker.host=MYDOMAIN.COM worker.apacheworker.port=8009 worker.apacheworker.lbfactor=1 worker.apacheworker.connection_pool_timeout=600 worker.apacheworker.socket_keepalive=1 </code></pre> <p>If I'm right, the <code>JkMount</code> directive is a relative path in my apache folder. I tried it as an absolute path as well but that doesn't work either. </p> <p>So I don't have an actual directory at my <code>/var/www/webservices</code>, but I do have a symbolic link (with that exact path) pointing to my <code>/var/lib/tomcat7/webapps</code> directory. This way, when I copy a <code>.war</code>-file into my <code>webapps</code>-directory, it gets deflated automatically by tomcat (that works) and it should be accessible from my address "MYDOMAIN.COM/webservices/MYNEWAPP".</p> <p>However, it doesn't work. Is there anyone that can enlighten me in what I'm exactly doing wrong? Right now, when trying to open the page, I get the code just showing up - so it's not being processed at all.</p> <p>Thanks in advance!</p> <hr> <p><em><strong>EDIT</em></strong> So I tried the following: </p> <ul> <li>I already had placed <code>localhost</code> instead of my own domain in the <code>workers.properties</code></li> <li>I dropped the <code>lbfactor</code></li> </ul> <p>This is how my <code>workers.properties</code> file looks like now:</p> <pre><code># the list of workers worker.list=apacheworker # define the workers properties worker.apacheworker.type=ajp13 worker.apacheworker.host=localhost worker.apacheworker.port=8009 worker.apacheworker.connection_pool_timeout=600 worker.apacheworker.socket_keepalive=1 </code></pre> <p>Further more, I changed my <code>/etc/apache2/apache2.conf</code> as well (I don't use a separate <code>mod_jk.conf</code>), to block access to my WEB-INF directory and remove the unneccessary mappings:</p> <pre><code># Tomcat LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so # jk_mod properties JkWorkersFile /var/lib/tomcat7/conf/workers.properties JkLogFile /var/log/apache2/mod_jk.log JkLogLevel error JkLogStampFormat "[%a %b %d %H:%M:%S %Y] " # map requests to these folders to the tomcat worker JkMount /webservices/* apacheworker &lt;Location "/Hello_World/WEB-INF"&gt; AllowOverride None deny from all &lt;/Location&gt; </code></pre> <p>All this didn't help (restarted both apache and tomcat servers as well). I still see the source from my .jsp file: </p> <pre><code>&lt;%@page contentType="text/html" pageEncoding="UTF-8"%&gt; &lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"&gt; &lt;title&gt;JSP Page&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;h1&gt;Hello World!&lt;/h1&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Where I think I lost you: </p> <pre><code>"Notice that by default the URI for your war is the name of the war file, so that myapp.war will be accessed by calling http://mydomain.com/myapp, not http://mydomain.com/webservices/myapp. The /webservices/ mapping is relevant only if you have a webservices.war file in the tomcat's webapps directory. " </code></pre> <p>So, my webserver (<code>apache httpd</code>) serves everythings that is in my <code>/var/www/</code> directory. In that directory, I have a symlink called <code>webservices</code> that points directly to my <code>tomcat_home\webapps</code> folder. So, calling <code>ls -la</code> gives me this:</p> <pre><code>lrwxrwxrwx 1 root root 24 Nov 16 16:48 webservices -&gt; /var/lib/tomcat7/webapps </code></pre> <p>In that <code>webapps</code> folder I have my actual .war files, including Hello_World. So I don't know how I'd need to reach those files by typing in "<a href="http://mydomain.com/Hello_World" rel="nofollow">http://mydomain.com/Hello_World</a>" - that simply gives me a 404...</p> <p>Thanks for helping me out!</p>
