I'm following instructions found in Java All in one for Dummies 3rd edition
I downloaded tomcat and followed all the steps for setting it up, step 6 says. "Modify the web.xml file to enable the invoker servlet" It says to find the lines of code for the invoker and then comment them. I am currently in the web.xml file and searched for invoke, but nothing came up... should I code the invoker in myself? or umcomment a different line?(this book is 4 years old and may be outdated) Or just not change anything at all?
I've just take a quick look up to the book and on page 407, there are the lines that you have to decomment or/else if not exist, add.
From the book;
<!--
<servlet>
<servlet-name>invoker</servlet-name>
<servlet-class>
org.apache.catalina.servlets.InvokerServlet
</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
-->
Anything located in between the "<!--" and "-->" will be interpreted as comments, which won't have any functional effect.
What you have to do is, to delete/remove the "<!--" and "-->" parts of this. Which is;
<servlet>
<servlet-name>invoker</servlet-name>
<servlet-class>
org.apache.catalina.servlets.InvokerServlet
</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
As it is written on the book, on the same "web.xml" file, you also have to find the lines below;
<!--
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping
-->
And commenting out them to make them visible to the tomcat, as removing the same comment lines, like below;
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping
Remember, you all have to execute these on the web.xml file.
And one more thing, If you cannot find these two parts, you can simply add these as below;
Just add them to the web.xml file as is;
<servlet>
<servlet-name>invoker</servlet-name>
<servlet-class>
org.apache.catalina.servlets.InvokerServlet
</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping
