[Helma-user] Running under Tomcat

[Maksim Lin for technical support mailling lists]

Hi again Patrick,

I actually looked at the stack trace this time! :-)
Looks like you might have a typo in your web.xml file, since the cause
of the exception is just that it can't find the application parameter
from there.

What I did was downloaded the tomcat6 zip file and unzipped I on my pc.
Then following the instructions on the lamtha wiki page:
* create a "helma" folder  in the tomcat-install/webapps folder  
* create a WEB-INF and a lib folder  *inside* the
tomcat-install/webapps/helma folder  .
* copy all the jars (expect servlet.jar) from helma/lib into the
tomcat-install/webapps/helma/lib folder

Then into the WEB-INF folder I just copy/pasted the web.xml example from
the wiki and just changed the settings to use the welcome app:

<init-param>
      <param-name>application</param-name>
      <param-value>welcome</param-value>
    </init-param>

    <init-param>
      <param-name>appdir</param-name>
      <param-value>/helma/helma-1.6.0/apps/welcome</param-value>
    </init-param>

    <init-param>
      <param-name>dbdir</param-name>
      <param-value>/helma/helma-1.6.0/db/welcome</param-value>
    </init-param>

of course you'll want to use your own paths to where you unzipped
helma...

the above should give you a display of the welcome apps "Welcome to
Helma" page (minus the css and images which I think would need fixing up
with settings for the "static" path).

also make sure you "reload" the helma servlet (eg. using Tomcat Manager
webapp at: http://localhost:8080/manager) everytime you make a change to
the web.xml settings.

hope that helps...

Maks.
