Try this. But, I hope someone has an easier way.<br />
String path = getServletContext().getRea<wbr />lPath(&quot;/&quot;)<wbr />;<br />
String tomcat = &nbsp;path.substring(0,path.last<wbr />IndexOf(re<wbr />quest.getC<wbr />ontextPath<wbr />())); &nbsp; &nbsp; 
</div>


Try this. But, I hope someone has an easier way.
String path = getServletContext().getRealPath("/");
String tomcat =  path.substring(0,path.lastIndexOf(request.getContextPath()));

I'm not sure whether you are looking for this or not.<br />
<br />
some.jsp<br />
======<br />
&lt;%<br />
&nbsp; String realPath = application.getRealPath(&quot;s<wbr />ome.jsp&quot;);<wbr /><br />
%&gt;
</div>

some.jsp
======
<%
  String realPath = application.getRealPath("some.jsp");
%>

<div>
this works for me:<br />
<br />
String temp = System.getProperty(&quot;tomcat<wbr />.home&quot;);<br />
out.print(temp);
</div>


this works for me:

String temp = System.getProperty("tomcat.home");
out.print(temp);

<div>
Yes, bobbit's code is easier.
</div>


<div>
hmm, tomcat.home returns null for me...<br />
but getServletContext().getRea<wbr />lPath(&quot;/&quot;)<wbr />; return exactly what i wanted
</div>


hmm, tomcat.home returns null for me...
but getServletContext().getRealPath("/"); return exactly what i wanted

<div class="content wysiwyg-content">
is there a java variable or method that can return tomcat's document root?

is there a java variable or method that can return tomcat's document root?

java variable for tomcat document root?

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
