Subject Re: Running CGI (Perl) => Can't load module DBI
Date Wed, 09 Jul 2008 08:00:43 GMT

I found a solution...

Instead of setting this in my web.xml:
<servlet>
    <servlet-name>cgi</servlet-name>
    <servlet-class>org.apache.catalina.servlets.CGIServlet</servlet-class>
    <init-param>
        <param-name>debug</param-name>
        <param-value>6</param-value>
    </init-param>
    <init-param>
        <param-name>cgiPathPrefix</param-name>
        <param-value>WEB-INF/cgi</param-value>
    </init-param>
    <load-on-startup>5</load-on-startup>
</servlet>

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

I added this to my servlet:
<init-param>
    <param-name>passShellEnvironment </param-name>
    <param-value>true</param-value>
</init-param>


Now I have access to my environment variables in my perl script (running on
the Tomcat server)
