If this value is present but a file does not exist, then globalXsltFile will be used. If globalXsltFile does not exist, then the default directory listing will be shown. This must be a file in the directory where the listing will take place to with a. This overrides globalXsltFile and contextXsltFile.
If this value is present but a file does not exist, then contextXsltFile will be used. If contextXsltFile does not exist, then globalXsltFile will be used. This setting must be one of true remove the BOM and use it in preference to fileEncoding , false remove the BOM but do not use it or pass-through do not use the BOM and do not remove it.
Use a negative value to always disable sendfile. If not, then that method isn't for you You can use either localXsltFile or globalXsltFile and DefaultServlet will create an xml document and run it through an xsl transformation based on the values provided in localXsltFile and globalXsltFile. Use web. See the security section of the Servlet specification. The readonly attribute is optional and defaults to true if not supplied. If the XML is writeable then it will be written to when Tomcat starts.
Ensure that these are appropriate to maintain the security of your installation. If referenced in a Realm, the UserDatabase will, by default, monitor pathname for changes and reload the file if a change in the last modified time is observed.
This can be disabled by setting the watchSource attribute to false. Configure a UserDatabase Realm to use this resource as described in the Realm configuration documentation. Tomcat also include a UserDatabase that uses a DataSource resource as the backend. The backend resource must be declared in the same JNDI context as the user database that will use it.
The database shema for the user database is flexible. It can be the same as the schema used for the DataSourceRealm , with only a table for users user name, password , and another one listing the roles associated with each user.
To support the full UserDatabase features, it must include additional tables for groups, and is compatible with referential integrity between users, groups and roles. The minimal schema without the ability to use groups will be it is the same as for the DataSourceRealm :. Please refer to the DataSource resources documentation for further instructions.
If the database is writeable then changes made through the Tomcat management to the UserDatabase can be persisted to the database using the save operation. Name of the column, in the "groups", "group roles" and "user groups" tables, that contains the group's name.
Name of the "group roles" table, which must contain columns named by the groupNameCol and roleNameCol attributes. Name of the "groups" table, which must contain columns named by the groupNameCol attribute. If this is set to true , then changes to the UserDatabase can be persisted to the DataSource by using the save method.
The default value is true. Name of the column, in the "roles" and "groups" tables, that contains the description for the roles and groups. Name of the column, in the "roles", "user roles" and "group roles" tables, which contains a role name assigned to the corresponding user. This attribute is required in majority of configurations. See allRolesMode attribute of the associated realm for a rare case when it can be omitted.
Name of the "roles" table, which must contain columns named by the roleNameCol attribute. Name of the column, in the "users" table, which contains the user's credentials i. If a CredentialHandler is specified, this component will assume that the passwords have been encoded with the specified algorithm.
Otherwise, they will be assumed to be in clear text. Name of the "user groups" table, which must contain columns named by the userNameCol and groupNameCol attributes. Name of the column, in the "users", "user groups" and "user roles" tables, that contains the user's username. Name of the "user roles" table, which must contain columns named by the userNameCol and roleNameCol attributes. Name of the "users" table, which must contain columns named by the userNameCol and userCredCol attributes.
In many web applications, sending electronic mail messages is a required part of the system's functionality. The Java Mail API makes this process relatively straightforward, but requires many configuration details that the client application must be aware of including the name of the SMTP host to be used for message sending.
Tomcat includes a standard resource factory that will create jakarta. For example, you can create an environment entry like this:. The fully qualified Java class name expected by the web application for this environment entry. The parameter value that will be presented to the application when requested from the JNDI context.
This value must be convertable to the Java type defined by the type attribute. If you have implemented a Java object that needs to know when this Context is started or stopped, you can declare it by nesting a Listener element inside this element.
The class name you specify must implement the org. It will be notified about the occurrence of the corresponding lifecycle events. Configuration of such a listener looks like this:. Note that a Listener can have any number of additional properties that may be configured from this element.
Attribute names are matched to corresponding JavaBean property names using the standard property method naming patterns. You can ask Catalina to check the IP address, or host name, on every incoming request directed to the surrounding Engine , Host , or Context element. Requests that come from locations that are not accepted will be rejected with an HTTP "Forbidden" error. Example filter declarations:.
See Remote Address Filter and Remote Host Filter for more information about the configuration options that are supported. You MUST also define the needed resource parameters as attributes of the Resource element, to configure the object factory to be used if not known to Tomcat already , and the properties used to configure that object factory.
Specify whether the web Application code signs on to the corresponding resource manager programmatically, or whether the Container will sign on to the resource manager on behalf of the application. The value of this attribute must be Application or Container. Name of the zero-argument method to call on a singleton resource when it is no longer required. This is intended to speed up clean-up of resources that would otherwise happen as part of garbage collection.
This attribute is ignored if the singleton attribute is false. For javax. DataSource and javax. This may be disabled by setting the attribute to the empty string. For all other resource types no default is defined and no close method will be called by default. Specify whether connections obtained through this resource manager can be shared. The value of this attribute must be Shareable or Unshareable. By default, connections are assumed to be shareable.
Specify whether this resource definition is for a singleton resource, i. If this attribute is true , multiple JNDI lookups for this resource will return the same object. If this attribute is false , multiple JNDI lookups for this resource will return different objects. This attribute must be true for javax. The value of this attribute must be true or false. By default, this attribute is true. The fully qualified Java class name expected by the web application when it performs a lookup for this resource.
This element is used to create a link to a global JNDI resource. Doing a JNDI lookup on the link name will then return the linked global resource. The fully qualified Java class name expected by the web application when it performs a lookup for this resource link. The fully qualified Java class name for the class creating these objects.
This class should implement the javax. ObjectFactory interface. DataSourceLinkFactory" the resource link can be used with two additional attributes to allow a shared data source to be used with different credentials.
When these two additional attributes are used in combination with the javax. DataSource type, different contexts can share a global data source with different credentials. Under the hood, what happens is that a call to getConnection is simply translated to a call getConnection username, password on the global data source.
This is an easy way to get code to be transparent to what schemas are being used, yet be able to control connections or pools in the global configuration. Warning: This feature works only if the global DataSource supports getConnection username, password method. See its Javadoc for BasicDataSource class. Apache Tomcat JDBC pool does support it, but by default this support is disabled and can be enabled by alternateUsernameAllowed attribute.
See its documentation for details. You MUST define an object factory class to instantiate this object as well as the needed resource parameters as attributes of the Transaction element, and the properties used to configure that object factory.
Links Docs Home Config Ref. Top Level Elements Server Service. Containers Context Engine Host Cluster. Parallel deployment You may deploy multiple versions of a web application with the same context path at the same time.
The rules used to match requests to a context version are as follows: If no session information is present in the request, use the latest version. If session information is present in the request, check the session manager of each version for a matching session and if one is found, use that version. If session information is present in the request but no matching session can be found, use the latest version. Naming When autoDeploy or deployOnStartup operations are performed by a Host, the name and context path of the web application are derived from the name s of the file s that define s the web application.
Some examples of these naming conventions are given below. If you want to deploy a WAR file or a directory using a context path that is not related to the base file name then one of the following options must be used to prevent double-deployment: Disable autoDeploy and deployOnStartup and define all Context s in server. In individual files with a ". The context path and version will be derived from the base name of the file the file name less the.
This file will always take precedence over any context. This setting is used in the following situations: the size of the request body is larger than the maxPostSize configured in the connector the size limit of a MultiPart upload is reached the servlet sets the response status to Request Entity Too Large Not reading the additional data will free the request processing thread more quickly.
The default is true , so additional data will be read. Standard Implementation The standard implementation of Context is org. You can nest at most one instance of the following utility components by nesting a corresponding element inside your Context element: Cookie Processor - Configure parsing and generation of HTTP cookie headers. Loader - Configure the web application class loader that will be used to load servlet and bean classes for this web application.

You cannot change this - why do you want to? JoseK - Your comment should be posted as the answer - up votes ahoy! Actually, I wanted to run eclipce's project structure into tomcat.
