Servlet declaration and mapping replace your Web

In Apache 5.0 and 5.5, I need to modify the Servlet name and class name in the web. xml file for each program. These are not seen in Apache Tomcat 4.0. Why?

Jeff Hanson replied: According to Tomcat 5.0 release instructions:

"Let web applications ask CGI and SSI, which is used when a Security Manager program (for example, a malicious Web application can use them to bypass security management programs for Access Control) creates security issues. In Tomcat 5.0, they are all set as not permitted, because our goal is to provide a completely secure default setting. However, CGI and SSI are still usable ."

How to use CGI:

Rename the file $ CATALINA_HOME/server/lib/Servlets-cgi.renametojar to $ CATALINA_HOME/server/lib/Servlets-cgi.jar.

#8226; in the file $ CATALINA_HOME/conf/web. xml, you need to remove the Servlet declaration and mapping from the gaze in two places. The Servlet declaration looks like the following ::

 
 

  
  
<servlet> 
  
  
<servlet-name>cgi</servlet-name> 
  
  
...  
  
  
</servlet> 
 
 

Servlet ing looks similar to the following:

 
 

  
  
<servlet-mapping> 
  
  
<servlet-name>cgi</servlet-name> 
  
  
<url-pattern>/cgi-bin/*</url-pattern> 
  
  
</servlet-mapping> 
 
 

These Servlet declarations and ings can be added to your Web application deployment descriptor alternately.

Make SSI available:

? Rename the file $ CATALINA_HOME/server/lib/Servlets-ssi.renametojar to $ CATALINA_HOME/server/lib/Servlets-ssi.jar.

#8226; in the file $ CATALINA_HOME/conf/web. xml, you need to remove the Servlet declaration and mapping from the gaze in two places. The Servlet declaration looks similar to the following:

 
 

  
  
<servlet> 
  
  
<servlet-name>ssi</servlet-name> 
  
  
...  
  
  
</servlet> 
 
 

Servlet ing looks similar to the following:

 
 

  
  
<servlet-mapping> 
  
  
<servlet-name>ssi</servlet-name> 
  
  
<url-pattern>*.shtml</url-pattern> 
  
  
</servlet-mapping> 
 
 

These Servlet declarations and mappings can be added to your Web application deployment descriptor alternately.
