        <para>
            The class must be in the classpath (to add a package or a directory in the Java classpath, just use <link type="scilab" linkend="scilab.help/javaclasspath">javaclasspath</link>).
        </para>
        <para>
            When <literal>jimport("java.lang.String")</literal>, a mlist named String is created on the Scilab stack. The created mlist has a type equal to _JClass and can be used to instantiate new objects in using something like <literal>str = String.new("A Scilab String");</literal>. It is possible to call the static methods (if exist) of the class

                    Function introduced. Based on the 'JIMS' module. The main difference in the behavior compared to the JIMS module is that <link linkend="jautoUnwrap">jautoUnwrap</link> is enabled by default.
