Method Detail

getErrorOnUseBeanInvalidClassAttribute

boolean getErrorOnUseBeanInvalidClassAttribute()

Returns true if Jasper issues a compilation error instead of a runtime Instantiation error if the class attribute specified in useBean action is invalid.

getKeepGenerated

boolean getKeepGenerated()

Are we keeping generated code around?

isPoolingEnabled

boolean isPoolingEnabled()

Returns true if tag handler pooling is enabled, false otherwise.

getMappedFile

boolean getMappedFile()

Are we supporting HTML mapped servlets?

getClassDebugInfo

boolean getClassDebugInfo()

Should we include debug information in compiled class?

getCheckInterval

int getCheckInterval()

Background compile thread check interval in seconds

getDevelopment

boolean getDevelopment()

Is Jasper being used in development mode?

getDisplaySourceFragment

boolean getDisplaySourceFragment()

Should we include a source fragment in exception messages, which could be displayed to the developer ?

isSmapSuppressed

boolean isSmapSuppressed()

Is the generation of SMAP info for JSR45 debugging suppressed?

isSmapDumped

boolean isSmapDumped()

Indicates whether SMAP info for JSR45 debugging should be dumped to a file. Ignored if suppressSmap() is true.

getTrimSpaces

boolean getTrimSpaces()

Should white spaces between directives or actions be trimmed?

getIeClassId

String getIeClassId()

Gets the class-id value that is sent to Internet Explorer when using <jsp:plugin> tags.

Returns:

Class-id value

getScratchDir

File getScratchDir()

What is my scratch dir?

getClassPath

String getClassPath()

What classpath should I use while compiling the servlets generated from JSP files?

getCompiler

String getCompiler()

Compiler to use.

If null (the default), the java compiler from Eclipse JDT project, bundled with Tomcat, will be used. Otherwise, the javac task from Apache Ant will be used to call an external java compiler and the value of this option will be passed to it. See Apache Ant documentation for the possible values.

getCompilerTargetVM

String getCompilerTargetVM()

The compiler target VM, e.g. 1.1, 1.2, 1.3, 1.4, 1.5 or 1.6.

getCompilerSourceVM

String getCompilerSourceVM()

The compiler source VM, e.g. 1.3, 1.4, 1.5 or 1.6.

getCompilerClassName

String getCompilerClassName()

Jasper Java compiler class to use.

getTldCache

TldCache getTldCache()

The cache that maps URIs, resource paths and parsed TLD files for the various tag libraries 'exposed' by the web application. A tag library is 'exposed' either explicitly in web.xml or implicitly via the uri tag in the TLD of a taglib deployed in a jar file (WEB-INF/lib).

Returns:

the instance of the TldLocationsCache for the web-application.

getJavaEncoding

String getJavaEncoding()

Java platform encoding to generate the JSP page servlet.

getFork

boolean getFork()

The boolean flag to tell Ant whether to fork JSP page compilations.

Is used only when Jasper uses an external java compiler (wrapped through a javac Apache Ant task).

getJspConfig

JspConfig getJspConfig()

Obtain JSP configuration information specified in web.xml.

isXpoweredBy

boolean isXpoweredBy()

Is generation of X-Powered-By response header enabled/disabled?

getTagPluginManager

TagPluginManager getTagPluginManager()

Obtain a Tag Plugin Manager

genStringAsCharArray

boolean genStringAsCharArray()

Indicates whether text strings are to be generated as char arrays.

Returns:

true if text strings are to be generated as char arrays, false otherwise

getModificationTestInterval

int getModificationTestInterval()

Modification test interval.

getRecompileOnFail

boolean getRecompileOnFail()

Re-compile on failure.

isCaching

boolean isCaching()

Is caching enabled (used for precompilation).

getCache

Map<String,TagLibraryInfo> getCache()

The web-application wide cache for the TagLibraryInfo tag library descriptors, used if isCaching() returns true.

Using this cache avoids the cost of repeating the parsing of a tag library descriptor XML file (performed by TagLibraryInfoImpl.parseTLD).

Returns:

the Map(String uri, TagLibraryInfo tld) instance.

getMaxLoadedJsps

int getMaxLoadedJsps()

The maximum number of loaded jsps per web-application. If there are more jsps loaded, they will be unloaded. If unset or less than 0, no jsps are unloaded.

getJspIdleTimeout

int getJspIdleTimeout()

The idle time in seconds after which a JSP is unloaded. If unset or less or equal than 0, no jsps are unloaded.
