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?

### getSendErrorToClient

    @Deprecated
    boolean getSendErrorToClient()

  Deprecated.

  Should errors be sent to client or thrown into stderr?

### 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 is suppressSmap() is true

### getTrimSpaces

    boolean getTrimSpaces()

  Should white spaces between directives or actions be trimmed?

### getIeClassId

    java.lang.String getIeClassId()

  Class ID for use in the plugin tag when the browser is IE.

### getScratchDir

    java.io.File getScratchDir()

  What is my scratch dir?

### getClassPath

    java.lang.String getClassPath()

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

### getCompiler

    java.lang.String getCompiler()

  Compiler to use.

### getCompilerTargetVM

    java.lang.String getCompilerTargetVM()

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

### getCompilerSourceVM

    java.lang.String getCompilerSourceVM()

  Compiler source VM, e.g. 1.3, 1.4, or 1.5.
