Using Java Servlets With Subsystem Web Forms; Supported Web Browsers; Supported Character Sets - Red Hat CERTIFICATE SYSTEM 8 - AGENTS GUIDE Agents Manual

1.5. Using Java Servlets with Subsystem Web Forms

Each subsystem Java™ servlet supports a parameter called xml, which can have a value of either
true or false. This parameter sets what kind of data the servlet returns; by default all of the
subsystem interfaces, like the agent services page or the end-entities page, returns data in HTML.
Setting the xml with a value of true returns XML data. This XML information is useful for writing
scripts that interact with the server.
The xml parameter is appended to the end of the interface link. For example, the server returns an
HTML page when the following link is accessed:
https://server.example.com:9444/ca/ee/ca/displayBySerial?op=displayBySerial&serialNumber=0x1
Appending xml=true to the end of the link returns the same page in XML:
https://server.example.com:9444/ca/ee/ca/displayBySerial?
op=displayBySerial&serialNumber=0x1&xml=true

1.6. Supported Web Browsers

The services pages for the subsystems require a web browser that supports SSL. Two browsers are
supported:
• Mozilla Firefox 2.0 and higher
• Microsoft Internet Explorer 6 and higher on both Windows XP and Vista
Red Hat strongly recommends that agents and administrators use Mozilla Firefox to access the agent
services pages.
NOTE
Browsers for Mac, such as Safari, and other types of web browsers, such as Opera, are
not supported for the agent services pages. This means that some operations may not
complete successfully or forms may not be displayed properly.

1.7. Supported Character Sets

Red Hat Certificate System fully supports UTF-8 characters in the CA end users forms for specific
fields. This means that end users can submit certificate requests with UTF-8 characters in those fields
and can search for and retrieve certificates and CRLs in the CA and retrieve keys in the DRM when
using those field values as the search parameters.
Four fields fully-support UTF-8 characters:
• Common name (used in the subject name of the certificate)
• Organizational unit (used in the subject name of the certificate)
• Requester name
