Interface IApplicationContext

All Known Implementing Classes:

PortletApplicationContext, StandaloneApplicationContext, WebApplicationContext

public interface IApplicationContext

Defines a set of methods to retrieve information about the application environment.

There is one context per server application (web application), so the class can be used as a place to share global application data.

Method Detail

getSolutionPath

String getSolutionPath(String path)

Retrieves the fully qualified path to the location of the Pentaho solution, appending the path given in the parameter. The path is formatted appropriately for the platform that the application is running on.

Parameters:

path - a path to a location that exists relative to the solution tree

Returns:

fully qualified path to the requested location in the solution tree

getSolutionRootPath

String getSolutionRootPath()

getFileOutputPath

String getFileOutputPath(String path)

Used for content output (temporary and otherwise), returns a fully qualified path suitable for creating a File object from.

Parameters:

path - Relative path within the solution to the file location. Solution path will be pre-pended

Returns:

Fully qualified path

getPentahoServerName

String getPentahoServerName()

Retrieves the descriptive name of the platform application.

The Pentaho server name should specified in the system settings configuration file, using the name element

Returns:

the descriptive server name as specified in the system settings, or "Pentaho Business Intelligence Platform" by default.

getBaseUrl

String getBaseUrl()

Deprecated. Returns a URL to the server application, up to and including the context.

The URL that is returned is derived from the server context, and thus will include the protocol, host name, port, and application context root.

Returns:

the URL to the server application context root. Use getFullyQualifiedServerURL instead

getFullyQualifiedServerURL

String getFullyQualifiedServerURL()

Returns a fully qualified URL to the server application, up to and including the context.

This method should only be used if delivering an offline content or in a scenario where fully qualified url is required.

Returns:

the URL to the server application context root.

getApplicationPath

String getApplicationPath(String path)

Returns the path to the web application or standalone application. This is only used in a few places, like loading the portlet localization messages.

Parameters:

path - a path to a location that exists relative to the application root directory

Returns:

the path to the server application root

getProperty

String getProperty(String key)

If there were any other properties set (for example, initParams in the servlet context), this will let you have access to all of those properties that are set.

Parameters:

key - property Name

Returns:

string property value

getProperty

String getProperty(String key,
                   String defaultValue)

If there were any other properties set (for example, initParams in the servlet context), this will let you have access to all of those properties that are set.

Parameters:

key - property Name

defaultValue - default value if the property is not specified.

Returns:

string property value

addEntryPointHandler

Adds an entry point handler. The entry point handler is called when actions start on a particular thread.

Parameters:

entryPoint -

removeEntryPointHandler

void removeEntryPointHandler(IPentahoSystemEntryPoint entryPoint)

Removes an entry point handler.

Parameters:

setFullyQualifiedServerURL

void setFullyQualifiedServerURL(String url)

setBaseUrl

void setBaseUrl(String url)

Parameters:

url - Use setFullyQualifiedServerURL instead

setSolutionRootPath
