Method Details
-
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.- Returns:
trueto get an error
-
getKeepGenerated
boolean getKeepGenerated()- Returns:
trueto keep the generated source
-
isPoolingEnabled
boolean isPoolingEnabled()- Returns:
trueif tag handler pooling is enabled,falseotherwise.
-
getMappedFile
boolean getMappedFile()- Returns:
trueif HTML mapped Servlets are supported.
-
getClassDebugInfo
boolean getClassDebugInfo()- Returns:
trueif debug information in included in compiled classes.
-
getCheckInterval
int getCheckInterval()- Returns:
- background compile thread check interval in seconds
-
getDevelopment
boolean getDevelopment()Main development flag, which enables detailed error reports with sources, as well automatic recompilation of JSPs and tag files. This setting should usually befalsewhen running in production.- Returns:
trueif Jasper is in development mode
-
getDisplaySourceFragment
boolean getDisplaySourceFragment()- Returns:
trueto include a source fragment in exception messages.
-
isSmapSuppressed
boolean isSmapSuppressed()- Returns:
trueto suppress generation of SMAP info for JSR45 debugging.
-
isSmapDumped
boolean isSmapDumped()This setting is ignored if suppressSmap() istrue.- Returns:
trueto write SMAP info for JSR45 debugging to a file.
-
getTrimSpaces
TrimSpacesOption getTrimSpaces()- Returns:
TrimSpacesOption.TRUEto remove template text that consists only of whitespace from the output completely,TrimSpacesOption.SINGLEto replace such template text with a single space,TrimSpacesOption.FALSEto leave such template text unchanged orTrimSpacesOption.EXTENDEDto remove template text that consists only of whitespace and to replace any sequence of whitespace and new lines within template text with a single new line.
-
getIeClassId
Deprecated.Will be removed in Tomcat 10.1.xGets the class-id value that is sent to Internet Explorer when using <jsp:plugin> tags.- Returns:
- Class-id value
-
getScratchDir
File getScratchDir()- Returns:
- the work folder
-
getClassPath
String getClassPath()- Returns:
- the classpath used to compile generated Servlets
-
getCompiler
String getCompiler()Compiler to use.If
null(the default), the java compiler from Eclipse JDT project, bundled with Tomcat, will be used. Otherwise, thejavactask 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.- Returns:
- the compiler name
-
getCompilerTargetVM
String getCompilerTargetVM()- Returns:
- the compiler target VM, e.g. 1.8.
-
getCompilerSourceVM
String getCompilerSourceVM()- Returns:
- the compiler source VM, e.g. 1.8.
-
getCompilerClassName
String getCompilerClassName()- Returns:
- 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()- Returns:
- 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
javacApache Ant task).- Returns:
trueto fork a process during compilation
-
getJspConfig
JspConfig getJspConfig()- Returns:
- JSP configuration information specified in web.xml.
-
isXpoweredBy
boolean isXpoweredBy()- Returns:
trueto generate a X-Powered-By response header.
-
getTagPluginManager
TagPluginManager getTagPluginManager()- Returns:
- a Tag Plugin Manager
-
genStringAsCharArray
boolean genStringAsCharArray()Indicates whether text strings are to be generated as char arrays.- Returns:
trueif text strings are to be generated as char arrays,falseotherwise
-
getModificationTestInterval
int getModificationTestInterval()- Returns:
- modification test interval.
-
getRecompileOnFail
boolean getRecompileOnFail()- Returns:
trueif re-compile will occur on a failure.
-
isCaching
boolean isCaching()- Returns:
trueis caching is enabled (used for precompilation).
-
getCache
Map<String,TagLibraryInfo> getCache()The web-application wide cache for the TagLibraryInfo tag library descriptors, used ifisCaching()returnstrue.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.- Returns:
- The JSP count
-
getJspIdleTimeout
int getJspIdleTimeout()- Returns:
- the idle time in seconds after which a JSP is unloaded. If unset or less or equal than 0, no jsps are unloaded.
-
getStrictQuoteEscaping
boolean getStrictQuoteEscaping()- Returns:
trueif the quote escaping required by section JSP.1.6 of the JSP specification should be applied to scriplet expression.
-
getQuoteAttributeEL
boolean getQuoteAttributeEL()- Returns:
trueif EL expressions used within attributes should have the quoting rules in JSP.1.6 applied to the expression.
-
getGeneratedJavaAddTimestamp
default boolean getGeneratedJavaAddTimestamp()Should the container include the time the file was generated in the comments at the start of a Java file generated from a JSP or tag. Defaults totrue.- Returns:
trueto include the timestamp, otherwise don't include it
