      • getCompiler

        String getCompiler()
        Compiler to use.

        If null (the default), the java compiler from Eclipse JDT project, bundled with Tomcat, will be used.

        the compiler name
      • getCompilerTargetVM

        String getCompilerTargetVM()
        Returns:

      • 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()

      • 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).

        Returns:
        true to fork a process during compilation
      • getJspConfig

        JspConfig getJspConfig()
