Re: CGI environment vars

[Tim Funk]

O sweet sweet source code for CGIServlet.java ....

http://cvs.apache.org/viewcvs.cgi/jakarta-tomcat-4.0/catalina/src/share/org/apache/catalina/servlets/CGIServlet.java?rev=1.11&content-type=text/vnd.viewcvs-markup


Heres the deal: Look for the method:
protected boolean setCGIEnvironment(HttpServletRequest req)

and you'll see the environment be created. This environment is passed to the script. So you are SOL I think.

But there is hope ... write a wrapper shell script around your real CGI script like this and you might luck out:
----------------------------------
#!/bin/sh
export CRAP=mycrap
. /pull/in/some/file

exec real_cgi_name
----------------------------------

I haven;t seen this discussed yet, you are exporting your variables in setenv.sh AND setenv.sh is located in $CATALINA_HOME/bin?

Example:
--------
export WACKY=very

or

ANSWER=42
export ANSWER
--------

Already tried this and it didn't work.  Both in the setenv.sh (checked

and read by catalina.sh) and startup.sh.  It seems that's for the Tomcat
running environment but is not transferred to the CGIServlet's exec
environment.

What about setting the variable yourself in the catalina.sh script? If that doesn't work, make sure that the variable is exported (so that it remains in the super shell when the sub shell exits). Example:

LD_LIBRARY_PATH=.../.../ld.so; export LD_LIBRARY_PATH;

no no.. I'm using the CGI facility in Tomcat (see Tomcat docs).

There's

a

servlet set up to handle it already, and the CGI is getting executed

but

the

logs show that it's getting an error loading ld.so because it can't

find

it

(which is also the case when trying to run it in a shell without having
LD_LIBRARY_PATH set appropriately).

how about you do it yourself, I assume that you launch your CGI script
using Runtime.exec
in that case, use the method that

http://java.sun.com/j2se/1.4.1/docs/api/java/lang/Runtime.html

take a look at

Runtime.exec(java.lang.String,java.lang.String[],java.io.File)

Tomcat 4.1.18 : UMN Mapserver CGI

I have a CGI which needs to see the "LD_LIBRARY_PATH" to get to shared
libraries to run.  However, I can't seem to get whatever shell that

Tomcat

uses to run CGIs seeded with that variable.

I tried putting it in the "setenv.sh" which is checked for and used in
catalina.sh, but that doesn't seem to have any effect on CGIs.

Anyone have an idea?
