Method Detail

getApplication

public static Application getApplication(org.apache.catalina.Context context,
                                         ContainerWrapperBean containerWrapper)

Gets the application.

Parameters:

context - the context

containerWrapper - the container wrapper

Returns:

the application

getApplication

public static Application getApplication(org.apache.catalina.Context context,
                                         ResourceResolver resourceResolver,
                                         boolean calcSize,
                                         ContainerWrapperBean containerWrapper)

Creates Application instance from Tomcat Context object. If ResourceResolver is passed the method will also collect additional information about the application such as session count, session attribute count, application attribute count, servlet count, servlet stats summary and datasource usage summary. Collecting additional information can be CPU intensive and time consuming so this should be avoided unless absolutely required. Some datasource implementations (c3p0) are known to be prone to internal deadlocks, so this method can also hang is datasource usage stats is to be collected.

Parameters:

context - the context from which to create the Application

resourceResolver - the resolver to use for resources associated with the given context

calcSize - flag which controls whether to calculate session size

containerWrapper - the wrapper for the context's root containing server

Returns:

Application object

collectApplicationServletStats

public static void collectApplicationServletStats(org.apache.catalina.Context context,
                                                  Application app)

Calculates Sum of requestCount, errorCount and processingTime for all servlets for the given application. It also works out minimum value of minTime and maximum value for maxTime for all servlets.

Parameters:

context - the context whose stats will be collected

app - the application in which to store the collected stats

getApplicationDataSourceUsageScores

public static int[] getApplicationDataSourceUsageScores(org.apache.catalina.Context context,
                                                        ResourceResolver resolver,
                                                        ContainerWrapperBean containerWrapper)

Gets the application data source usage scores.

Parameters:

context - the context

resolver - the resolver

containerWrapper - the container wrapper

Returns:

the application data source usage scores

getApplicationSession

public static ApplicationSession getApplicationSession(org.apache.catalina.Session session,
                                                       boolean calcSize,
                                                       boolean addAttributes)

Gets the application session.

Parameters:

session - the session

calcSize - the calc size

addAttributes - the add attributes

Returns:

the application session

getApplicationAttributes

public static List<Attribute> getApplicationAttributes(org.apache.catalina.Context context)

Gets the application attributes.

Parameters:

context - the context

Returns:

the application attributes

                                                              ContainerWrapperBean containerWrapper)

Gets the application init params.

Parameters:

Returns:

the application init params

getApplicationServlet

public static ServletInfo getApplicationServlet(org.apache.catalina.Context context,
                                                String servletName)
