Constructor Detail

TldConfig

public TldConfig()

Method Detail

setNoTldJars

public static void setNoTldJars(String jarNames)

Sets the list of JARs that are known not to contain any TLDs.

Parameters:

jarNames - List of comma-separated names of JAR files that are known not to contain any TLDs.

addTaglibUri

public void addTaglibUri(String uri)

Adds a taglib URI to the list of known URIs.

isKnownTaglibUri

public boolean isKnownTaglibUri(String uri)

Determines if the provided URI is a known taglib URI.

isKnownWebxmlTaglibUri

public boolean isKnownWebxmlTaglibUri(String uri)

Determines if the provided URI is a known taglib URI.

getContext

@Deprecated
public Context getContext()

Deprecated. Unused - will be removed in 8.0.x

setContext

@Deprecated
public void setContext(Context context)

Deprecated. Unused - will be removed in 8.0.x

addApplicationListener

public void addApplicationListener(String s)

getTldListeners

public String[] getTldListeners()

execute

public void execute()

Scan for and configure all tag library descriptors found in this web application. This supports a Tomcat-specific extension to the TLD search order defined in the JSP spec. It allows tag libraries packaged as JAR files to be shared by web applications by simply dropping them in a location that all web applications have access to (e.g., /lib). It also supports some of the weird and wonderful arrangements present when Tomcat gets embedded. The set of shared JARs to be scanned for TLDs is narrowed down by the noTldJars class variable, which contains the names of JARs that are known not to contain any TLDs.

lifecycleEvent

public void lifecycleEvent(LifecycleEvent event)

Description copied from interface: LifecycleListener

Acknowledge the occurrence of the specified event.

Specified by:

lifecycleEvent in interface LifecycleListener

Parameters:

event - LifecycleEvent that has occurred
