Syntax Rules for Editing obj.conf

Several rules are important in the obj.conf file. Be very careful when editing this file. Simple mistakes can make the server fail to start or operate correctly.

Caution – Caution –

Do not remove any directives from any obj.conf file that are present in the obj.conf file that exists when you first install Sun Java System Web Server. The server may not function properly.

Order of Directives

The order of directives is important, since the server executes them in the order they appear in obj.conf. The outcome of some directives affect the execution of other directives.

For PathCheck directives, the order within the PathCheck section is not so important, since the server executes all PathCheck directives. However, the order within the ObjectType section is very important, because if an ObjectType directive sets an attribute value, no other ObjectType directive can change that value. For example, if the default ObjectType directives were listed in the following order (which is the wrong way around), every request would have its type value set to text/plain, and the server would never have a chance to set the type according to the extension of the requested resource.

ObjectType fn="force-type" type="text/plain"
ObjectType fn="type-by-extension"

Similarly, the order of directives in the Service section is very important. The server executes the first Service directive that matches the current request and does not execute any others.


The number and names of parameters depends on the function. The order of parameters on the line is not important.

Case Sensitivity

Items in the obj.conf file are case-sensitive including function names, parameter names, many parameter values, and path names.


The C language allows function names to be composed only of letters, digits, and underscores. You may use the hyphen (-) character in the configuration file in place of underscore (_) for your C code function names. This is only true for function names.


Quotes (") are only required around value strings when there is a space in the string. Otherwise they are optional. Each open-quote must be matched by a close-quote.


Line Continuation

A long line may be continued on the next line by beginning the next line with a space or tab.

Path Names

Always use forward slashes (/) rather than backslashes (\) in path names under Windows. Backslash escapes the next character.


Comments begin with a pound (#) sign. If you manually add comments to obj.conf, then use the Server Manager interface to make changes to your server, the Server Manager will wipe out your comments when it updates obj.conf.
