F.A.Q. Listings:
| Detailed Responses:
What is a Servlet engine and why do I need one?
A Servlet engine is software that extends/"hooks into" web server software
(such as IIS, or Apache) to enable the web server software to execute Servlets and JSPs (Java programs that run within
a Servlet/JSP Engine). By using the Java programming
language, Servlets efficiently use server resources to transact data
between backend systems and users, giving developers the ability to create
complex web-based applications that operate with better speed and performance
than traditional internet software programs such as CGI.
ArcIMS uses Java Servlet technology within its architecture (the ArcIMS Servlet Connector) to display
maps in a web browser, which necessitates using a Servlet engine
such as ServletExec.
Why should I choose ServletExec as my Servlet engine?
Our customers using ServletExec in conjunction with ArcIMS
overwhelmingly make their purchase decision based on ServletExec's
ease of use. The ease in which ServletExec can be quickly
downloaded, installed and configured is an important consideration
because many are GIS professionals, and not software developers.
Besides ease-of-use, ServletExec is high performance, reliable
and standards-based (meaning that it will be compatible with
your Java applications, including ArcIMS) and can be used
to deploy other web-based applications.
Which *version* of ServletExec should I use with ArcIMS?
ServletExec 6.0 will be officially certified for use with ArcIMS 9.3 (once that version of ArcIMS has been released).
ServletExec 5.0 is officially certified for use with ArcIMS 9.2, 9.1, 9.0.1, & 9.0.
For previous versions of ArcIMS (4.x and 3.x), please use the appropriate
version of ServletExec 4.x, based on the this faq.
Note: Please remember to consider purchasing licenses with subscriptions,
enabling free upgrades for a period of two years from date of purchase. See
pricing for details.
Which *configuration* of ServletExec should I use with ArcIMS?
If using IIS 6 (or higher) as your webserver software then we strongly urge you to consider using the AS configuration of SE, rather than the ISAPI configuration.
There are many technical reasons we make this recommendation.
They are well documented in SE FAQ #364.
If you have questions or concerns about this, please send email to support@servletexec.com.
If you decide to use SE AS with ArcIMS 9.2 (or older) then you will need SE FAQ #346
What versions of ServletExec are supported with ArcIMS?
The answer to this question depends upon which version of ArcIMS you are using.
Generally, it can be said that ServletExec (6.0, 5.0, 4.2, 4.1.1) is fully supported with ArcIMS (9.3, 9.2, 4.0.1, 4.0 respectively) on various platforms (Windows, Linux,
Solaris, HP-UX, AIX) with various versions of the IIS & Apache webservers.
For specifics, please access the
ESRI ArcIMS System Requirements web page.
If you are an existing customer with a ServletExec X.y license key, you will be able
to upgrade to any X.z version for no additional cost, reusing the same license key. In other words, SE license keys are tied to
the major version, and work with all point releases of that major version.
If you require an older version of ServletExec, please contact us at
Sales.
Does it matter in what order I install ArcIMS and ServletExec?
Yes, per ArcIMS' installation instructions, you must install ServletExec
prior to installing ArcIMS. Refer to the installation pages for step-by-step
installation instructions.
How do I install ArcIMS and ServletExec from within a corporate firewall?
How does ServletExec determine which JDK or JRE to use?
I used the ServletExec Admin UI to make some configurations but after I restart ServletExec, the settings I entered are gone. What is wrong? Why did ServletExec forget my settings ?
I've installed ServletExec with Microsoft IIS but it doesn't work. What can I do to verify my installation?
How is ServletExec licensed?
ServletExec is licensed on a per-CPU basis. Categories include 1 CPU, 2 CPU, 4 CPU, & >4 CPU.
