Method Detail

preConfigure

public void preConfigure(WebAppContext context)
                  throws java.lang.Exception

Description copied from interface: Configuration

Set up for configuration.

Typically this step discovers configuration resources

Specified by:

preConfigure in interface Configuration

Overrides:

preConfigure in class AbstractConfiguration

Parameters:

context - The context to configure

Throws:

java.lang.Exception

configure

public void configure(WebAppContext context)
               throws java.lang.Exception

Description copied from interface: Configuration

Configure WebApp.

Typically this step applies the discovered configuration resources to either the WebAppContext or the associated MetaData.

Specified by:

configure in interface Configuration

Overrides:

configure in class AbstractConfiguration

Parameters:

context - The context to configure

Throws:

java.lang.Exception

deconfigure

public void deconfigure(WebAppContext context)
                 throws java.lang.Exception

Description copied from interface: Configuration

DeConfigure WebApp. This method is called to undo all configuration done. This is called to allow the context to work correctly over a stop/start cycle

Specified by:

deconfigure in interface Configuration

Overrides:

deconfigure in class AbstractConfiguration

Parameters:

context - The context to configure

Throws:

java.lang.Exception

cloneConfigure

public void cloneConfigure(WebAppContext template,
                  WebAppContext context)
                    throws java.lang.Exception

Description copied from interface: Configuration

Clone configuration instance.

Configure an instance of a WebAppContext, based on a template WebAppContext that has previously been configured by this Configuration.

Specified by:

cloneConfigure in interface Configuration

Overrides:

cloneConfigure in class AbstractConfiguration

Parameters:

template - The template context

context - The context to configure

Throws:

java.lang.Exception

See Also:

AbstractConfiguration.cloneConfigure(org.eclipse.jetty.webapp.WebAppContext, org.eclipse.jetty.webapp.WebAppContext)

resolveTempDirectory

public void resolveTempDirectory(WebAppContext context)

Get a temporary directory in which to unpack the war etc etc. The algorithm for determining this is to check these alternatives in the order shown:

A. Try to use an explicit directory specifically for this webapp:

1. Iff an explicit directory is set for this webapp, use it. Do NOT set delete on exit.
2. Iff javax.servlet.context.tempdir context attribute is set for this webapp && exists && writeable, then use it. Do NOT set delete on exit.

B. Create a directory based on global settings. The new directory will be called "Jetty_"+host+"_"+port+"__"+context+"_"+virtualhost Work out where to create this directory:

1. Iff $(jetty.home)/work exists create the directory there. Do NOT set delete on exit. Do NOT delete contents if dir already exists.
2. Iff WEB-INF/work exists create the directory there. Do NOT set delete on exit. Do NOT delete contents if dir already exists.
3. Else create dir in $(java.io.tmpdir). Set delete on exit. Delete contents if dir already exists.

makeTempDirectory

public void makeTempDirectory(java.io.File parent,
                     WebAppContext context,
                     boolean deleteExisting)
                       throws java.io.IOException

Throws:

java.io.IOException

unpack

public void unpack(WebAppContext context)
            throws java.io.IOException

Throws:

java.io.IOException

findWorkDirectory

public java.io.File findWorkDirectory(WebAppContext context)
                               throws java.io.IOException

Throws:

java.io.IOException

isTempWorkDirectory

public boolean isTempWorkDirectory(java.io.File tmpDir)

Check if the tmpDir itself is called "work", or if the tmpDir is in a directory called "work".

Returns:

true if File is a temporary or work directory

getCanonicalNameForWebAppTmpDir

public static java.lang.String getCanonicalNameForWebAppTmpDir(WebAppContext context)

Create a canonical name for a webapp temp directory. The form of the name is: "Jetty_"+host+"_"+port+"__"+resourceBase+"_"+context+"_"+virtualhost+base36_hashcode_of_whole_string host and port uniquely identify the server context and virtual host uniquely identify the webapp

Returns:

the canonical name for the webapp temp directory

findJars

protected java.util.List<Resource> findJars(WebAppContext context)
                                     throws java.lang.Exception

Look for jars in WEB-INF/lib

Parameters:

context -

Returns:

the list of jar resources found within context

Throws:

java.lang.Exception
