Look at the Session manager component and tweak accordingly. One way is to tell tomcat to persist sessions to a path which does not exist. (So tomcat will not store, or be able to load the sessions)

No! Nor can one accurately exist. Here's why

To disable tag pooling: See $TOMCAT_HOME/conf/web.xml --> enablePooling=false for the jsp servlet declaration.

Note: This option, as well as most other configuration options of JspServlet, affects code generation and compilation of JSP pages. It will not alter the behavior of JSPs that have already been compiled.

change the welcome file? ( I want to show index.jsp instead of index.html)

This is done in web.xml by changing welcome-files-list. More detail.

To make a global change, this is done in TOMCAT_HOME/conf/web.xml by changing the listings property for the default servlet.

If you want to enable it for an individual webapp, then you need to add something similar to the following to your web.xml file (for your individual app):

   <servlet>
       <servlet-name>listing</servlet-name>
       <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
       <init-param>
           <param-name>debug</param-name>
           <param-value>0</param-value>
       </init-param>
       <init-param>

Use the Content-Disposition header.

It is not broken, your tag probably is. Many bug reports have been filed about this. Bug 16001 has all the gory details. There is also a nice description of the life cycle.

Note, that this issue does not affect the SimpleTag tags and tag files of JSP 2.0 and later specifications, because those do not use tag pooling.

To disable tag pooling: See $TOMCAT_HOME/conf/web.xml --> enablePooling=false for the jsp servlet declaration.

Note: This option, as well as most other configuration options of JspServlet, affects code generation and compilation of JSP pages. It will not alter the behavior of JSPs that have already been compiled
