Determine Your Version of Tomcat using a JSP File
You can also check your version using a JSP file if you don’t have console access.
if you can upload a JSP file you may print out some info like in this example:bestdesigns.co.in/blog/check-jsp-tomcat-version
Save this code into a file called tomcat_version.jsp:
1 2 3 4 5 | <span class="typ">Tomcat</span> <span class="typ">Version</span> <span class="pun">:</span> <span class="pun"><%=</span><span class="pln"> application</span><span class="pun">.</span><span class="pln">getServerInfo</span><span class="pun">()</span> <span class="pun">%><</span><span class="pln">br</span><span class="pun">></span> <span class="typ">Servlet</span> <span class="typ">Specification</span> <span class="typ">Version</span> <span class="pun">:</span> <span class="pun"><%=</span><span class="pln"> application</span><span class="pun">.</span><span class="pln">getMajorVersion</span><span class="pun">()</span> <span class="pun">%>.<%=</span><span class="pln"> application</span><span class="pun">.</span><span class="pln">getMinorVersion</span><span class="pun">()</span> <span class="pun">%></span> <span class="pun"><</span><span class="pln">br</span><span class="pun">></span><span class="pln"> JSP version </span><span class="pun">:</span> <span class="pun"><%=</span><span class="typ">JspFactory</span><span class="pun">.</span><span class="pln">getDefaultFactory</span><span class="pun">().</span><span class="pln">getEngineInfo</span><span class="pun">().</span><span class="pln">getSpecificationVersion</span><span class="pun">()</span> <span class="pun">%><</span><span class="pln">br</span><span class="pun">></span> |
When you access, http://example.com/tomcat_version.jsp, the output should look similar to:
1 2 3 4 5 | <span class="typ">Tomcat</span> <span class="typ">Version</span> <span class="pun">:</span> <span class="typ">Apache</span> <span class="typ">Tomcat</span><span class="pun">/</span><span class="lit">5.5</span><span class="pun">.</span><span class="lit">25</span> <span class="typ">Servlet</span> <span class="typ">Specification</span> <span class="typ">Version</span> <span class="pun">:</span> <span class="lit">2.4</span><span class="pln"> JSP version</span><span class="pun">:</span> <span class="lit">2.0 </span> |
You can also find out the server information through its status page:
{running-tomcat-url}/manager/status
On that page you can see the version of Java on which your Tomcat runs
