The Mail Settings Panel

The Mail Settings panel of the System Settings page provides an interface for system administrators to configure email settings for Maple T.A.




MX Lookup


Find and use MX records for the given domain.

Domain Name


If the property "MX Lookup" is selected, you will need to provide the domain name.



Use a mail server from the server list.



If the property "Generic" is selected, you must provide a single server or a list of servers separated by a semicolon (;).

From Address

Defined during installation of Maple T.A

This is the address that will appear in the from field of any email sent.

User Name


The user name used to connect to the mail server (if needed).



The password used to connect to the mail server (if needed).



Determines whether email will be sent as HTML or text only.

Test Connection


The test connection button takes the settings that are in place and attempts to connect to the mail server. The user is informed whether or not the test was successful.

The Authentication Settings Panel

The System Administrator can control user authentication and validation through the Authentication Settings panel of the System Settings page.




Require User Validation


Values are "true" or "false". If "true", users logging in for the first time will be required to confirm their profile details such as first name, last name and email.

Enable LDAP

False (unchecked)

Checking the Enable LDAP box, means that Maple TA LDAP authentication needs to be configured through the ldap.properties file. For more information, see Chapter 6: Maple T.A. LDAP Authentication in the Maple T.A. System Administrator's Guide.

Allow Self Registration


Values are "true" or "false". If "true", users will see a link on the login page that allows them to register themselves. This feature is normally used only by Maple T.A. installations that are oriented towards placement testing.

The Maple Settings Panel

The local pool of Maple servers is a collection of instances of command-line Maple that are started as needed by Maple T.A. to compute versions of questions (for example, randomized questions) and to grade questions. This pool is configurable through the System Settings page. To access the System Settings page, select System Settings from the System Admin menu.

By default, Maple T.A. uses the local pool of servers. It is also possible to use Maplesoft's MapleNet product as an alternative to the local pool. There are two reasons for doing this:

1. Provide a wider range of question features including Maplets and gridlines on plots.

2. Scalability- the option of load balancing by running Maple T.A.'s Maple computations on a separate server.

Maple T.A.'s use of MapleNet is configured by properties in the System Admin user interface, under the Maple Settings section.

If all of the above properties are configured correctly, Maple T.A. will use MapleNet. Otherwise, Maple T.A. will use its local pool.

To confirm that Maple T.A. is using MapleNet, check mapleta.log. The following message will be issued at startup:

INFO This Maple T.A. instance uses MapleNet Services

Note that you will have to increase the log level for mapleta.log to INFO, from the default WARN, to see this message. For more information, see Chapter 4: Logging in the Maple T.A. System Administrator's Guide.

To configure MapleNet itself, refer to the MapleNet documentation. In particular, be aware that when Maple T.A. is configured to use MapleNet as the back-end math engine, and questions need access to files or custom libraries, the following may be required:

1. MapleNet may need to be run without security option "-z" to enable general access to the file system.

2. If Maple T.A. and MapleNet are running on two different servers, the absolute path to the library file from the Maple T.A. server needs to be identical to that seen by MapleNet on the other server. This can be done by copying the required files, or by using a shared network file system.




Use MapleNet

False (unchecked)

If unchecked, Maple T.A. will be used as a local pool of servers to compute versions of questions and to grade questions. If checked, MapleNet will be used instead.



The domain or subdomain address of the MapleNet server, for example, maplenet.myu.edu. MapleNet can run on the same machine as Maple T.A. In that case you would specify MAPLENET_SERVER=localhost.



The port number listened to by MapleNet on its server, for example 8180.

User Name


The username configured for MapleNet.



The password for MAPLENET_USER.

Maple Path

Defined during installation of Maple T.A

The path to Maple on the local machine.

Min Servers


Minimum number of Maple servers in the pool.

Max Servers


Maximum number of Maple servers in the pool.

Max Restarts


Maximum number of maple commands that will be sent to a Maple server before it is terminated and replaced with a fresh server.

CPU Limit (s)


Maximum number of CPU seconds that can be consumed by a Maple instance in the pool, before it is aborted (that is, assumed to be a "runaway").

Retry Delay (s)


Number of milliseconds to wait between requests for a Maple server instance, when all servers in the pool are busy.

Time Limit (s)


Time limit, in seconds, for a Maple statement to execute and return a result.

Plot Driver


Graphics format used to render plots. The choices are gif and jpeg.

Size Limit (kB)


Maximum size of data a Maple statement is allowed to generate.

Plot Height (px)


Plot height in pixels.

Plot Width (px)


Plot width in pixels.

Enable MathApp Question


Allow instructor to create Math App questions. Note that the MathApp questions use MapleNet.

Shared Math App File System

False (unchecked)

To use this option: check the Shared Math App File System box, then create a symbolic link that maps the Maple T.A. Public_Html/worksheets directory to a directory under MapleNet.

Note: This option is available on Linux only.

The Custom CSS Styles Panel

You can override the default styling in Maple TA by providing CSS styles. This allows you to customize the look of Maple T.A.'s fonts, colors, borders, etc.

The Filter Input Panel

You can set filters on Instructor and Student input that may: contain invalid HTML code, or cause cross site scripting vulnerabilities.

The Custom <head> HTML Panel

You can place custom code in the <head> tag of every Maple T.A. page. The custom code can be extra CSS, JavaScript files, custom scripts, etc.

The Custom footer HTML Panel

Code added to the Custom footer HTML panel is added just before the closing </body> tag. For best results regarding the appearance of this code on the web page, the code should include CSS.

The IP Address/Host Name Groups Panel

The System Administrator can define groups of IP address through the IP Address Groups panel of the System Settings page. IP addresses can be given individually, with wildcards, or using Netmask format. Enter only one IP address or pattern per line. For example, you might create groups that corresponding to computer labs at your institution.

Similarly, to restrict access to an assignment to specific host names, the system administrator can define a host name pattern such that only computers that match this pattern are allowed to complete the assignment. Host names must be entered with wildcards. For example, (*.maplesoft.com).

Groups that are defined in the system settings are available to instructors when they define the properties of assignments or tests. In the Assignment Editor, instructors can require students take an assignment from a restricted set of IP addresses or host names by selecting from a list of predefined groups set up by the system administrator or creating a custom IP address/host name restriction.

Note: To enable the host name restriction feature for instructors, the system administrator must configure Tomcat to actually do the host name lookups. This is done by adding "enableLookups" to the connector tag in the TOMCAT/conf/server.xml file. For example:

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" enableLookups="true"/>

After making this change to the connector tag, Tomcat must be restarted.
