Impressao de applet assinada

[sengedradog]

Pessoal,

Criei uma applet baseada na classe DocumentRender, listada logo abaixo. A função dela é imprimir uma url. O que fiz:
Adaptei a classe abaixo para ser uma applet.
Gerei um jar correspondente
Gerei a chave pelo keytool
assinei o jar com o jarsigner
exportei com keytool - export (não sei se é necessário tal passo)
quando executei a applet (por html ou appletviewer) deu erro de access denied da runtimeException.

Tentei também configurar a ferramenta policytool do java, mas não obtive sucesso. Alguém pode sugerir algo?

aí vai a classe Impressao

• The print method implements the Printable interface. Although Printables
• may be called to render a page more than once, each page is painted in
• order. We may, therefore, keep track of changes in the page being
• rendered by setting the currentPage variable to equal the pageIndex, and
• then comparing these variables on subsequent calls to this method. When
• the two variables match, it means that the page is being rendered for the
• second or third time. When the currentPage differs from the pageIndex, a
• new page is being requested.
• The highlights of the process used print a page are as follows:
• I. The Graphics object is cast to a Graphics2D object to allow for
• scaling. II. The JEditorPane is laid out using the width of a printable
• page. This will handle line breaks. If the JEditorPane cannot be sized at
• the width of the graphics clip, scaling will be allowed. III. The root
• view of the JEditorPane is obtained. By examining this root view and all
• of its children, printView will be able to determine the location of each
• printable element of the document. IV. If the scaleWidthToFit option is
• chosen, a scaling ratio is determined, and the graphics2D object is
• scaled. V. The Graphics2D object is clipped to the size of the printable
• page. VI. currentPage is checked to see if this is a new page to render.
• If so, pageStartY and pageEndY are reset. VII. To match the coordinates
• of the printable clip of graphics2D and the allocation rectangle which
• will be used to lay out the views, graphics2D is translated to begin at
• the printable X and Y coordinates of the graphics clip. VIII. An
• allocation Rectangle is created to represent the layout of the Views.
• The Printable Interface always prints the area indexed by reference to
• the Graphics object. For instance, with a standard 8.5 x 11 inch page
• with 1 inch margins the rectangle X = 72, Y = 72, Width = 468, and Height =
• 648, the area 72, 72, 468, 648 will be painted regardless of which page
• is actually being printed.
• To align the allocation Rectangle with the graphics2D object two things
• are done. The first step is to translate the X and Y coordinates of the
• graphics2D object to begin at the X and Y coordinates of the printable
• clip, see step VII. Next, when printing other than the first page, the
• allocation rectangle must start laying out in coordinates represented by
• negative numbers. After page one, the beginning of the allocation is
• started at minus the page end of the prior page. This moves the part
• which has already been rendered to before the printable clip of the
• graphics2D object.
• X. The printView method is called to paint the page. Its return value
• will indicate if a page has been rendered.
• Although public, print should not ordinarily be called by programs other
• than PrinterJob.

• printView is a recursive method which iterates through the tree structure

• attempts to render the view to the Graphics2D object.
• I. When any view starts after the beginning of the current printable
• page, this means that there are pages to print and the method sets
• pageExists to true. II. When a leaf view is taller than the printable
• area of a page, it cannot, of course, be broken down to fit a single
• page. Such a View will be printed whenever it intersects with the
• Graphics2D clip. III. If a leaf view intersects the printable area of the
• graphics clip and fits vertically within the printable area, it will be
• rendered. IV. If a leaf view does not exceed the printable area of a page
• but does not fit vertically within the Graphics2D clip of the current
• page, the method records that this page should end at the start of the
• view. This information is stored in pageEndY.
