Seam now includes a component set for generating documents using iText. To include PDF support in your application, put jboss-seam-pdf. There is no further configuration needed to use Seam’s iText support. The Seam iText module requires the use of Facelets as the view technology. Future versions of the library may also support the use of JSP. Additionally, it requires the use of the seam-ui package. It iyext proper deployment packaging, and it contains a number examples that demonstrate the key PDF generation features current supported.
Documents should always have the document tag at the sem of the document. A full list of supported pages sizes can be found in com. Alternatively, pageSize can provide the width and height of the page directly. Valid values are portrait and landscape.
In landscape mode, the height and width page sdam values are reversed.

Valid values are inlinewhich indicates the document should be displayed in the browser window if possible, and attachmentwhich indicates that the document should be treated as a download. The default value is inline. Useful documents will need to contain more than just text; however, the standard UI components are geared towards HTML generation and are itexh useful for generating PDF content. Most uses of text should be sectioned into paragraphs so that text fragments can be flowed, formatted and styled in logical groups.
The text tag allows text fragments to be produced from application data using normal JSF converter mechanisms. This will typically be a value binding expression.
The most common case is to support right to left direction fonts. Images can be loaded from the classpath or from the web application context using the value attribute. Resources can also be dynamically generated by application code. The imageData attribute can specify a value binding expression whose value is a java. This can be expressed as a single percentage value or as two percentage values representing separate x and y scaling percentages.
The image will be scale to fit those dimensions as closely as possible while preserving the XY ratio of the image. It supports the following attributes:.
Links to other points in the document should sewm with a ” “. For example, ” link1″ to refer to an anchor position with a name of link1. Links may also be a full URL to point to a resource outside of the document.
Header and footer declarations should appear at the beginning of a document. The current page number can be placed inside of a header or footer using the p: The page number tag can only be used in the context of a header or footer sema can only be used once.
Sections can only be used inside of chapters, but they may be nested arbitrarily deep.
Most PDF viewers provide easy navigation between chapters and sections in a document. The fourth section of the first section of chapter seaj would be section 3. To omit the chapter number, a number depth of 2 should be used. In that case, the section number would be displayed as 1.
Adding an unsigned signature to a PDF using Seam and iText
Any chapter or section can contain a p: The body of the title may contain raw text or may be a p: List structures can be displayed using the p: Lists may contain arbitrarily-nested sublists. List items may not be used outside of a list.
The following document uses the ui: If no style is given, itextt list items are bulleted. Table structures can be created using the p: Unlike many table structures, there is no explicit row declaration. If a table has 3 columns, then every 3 cells will automatically form a row. Header and footer rows can be declared, and the headers and footers will be repeated in the event a table structure spans multiple pages.
There should be one value for each column. This value seaj subtracted from the headerRows value. If document has 2 rows which make up the header and one row that makes up the footer, headerRows should be set to 3 and footerRows should be set to 1. Tables do not have the ability to span across multiple rows. Several ways of specifying colors are provided. A limited number of colors are supported by name. Colors can be specified as an integer value, as defined itrxt java.
Where alignment values are used, the Seam PDF supports the following horizontal alignment values: The vertical alignment values are topmiddlebottomand baseline. Charting support is also provided with jboss-seam-pdf. Charting requires the JFreeChart library jfreechart. Four types of charts are currently supported: Where greater variety or control is needed, it is possible to construct charts using Java code.
Alternatively, the value can the positive or negative angle in radians. It should be a number between 0 completely transparent and 1 completely opaque. Default value is true. If this is null, the background is not filled. If false, the chart is drawn as an ellipse.
The default is true. The default is clockwise. Category data can be broken down into series. The series tag is used to categorize a set of data with a series and apply styling to the entire series. The color component declares a color or gradient than can be referenced when drawing filled shapes. For gradient colors, this the starting color. Valid values are buttround and square. Valid values are miterround and bevel. The space separated integers indicate the length of each alternating drawn and undrawn segments.
Seam can use iText to generate barcodes in a wide variety of formats. These barcodes can be embedded in a PDF document or displayed as an image tiext a web page. Note that when sram with HTML images, barcodes can not currently display barcode text in the barcode. If you have a complex, pre-generated PDF with named fields, you can easily fill in the values from your application and present it to the user.
If the value has no protocol part: If set, no redirect will occur. Seam itextt provides experimental support for rendering Swing components into a PDF image. Some Swing look and feels supports, notably ones that use native widgets, will not render correctly. Document generation works out of the box with no additional configuration needed. Sea, there are a few points of configuration that are needed for more serious applications.
This capability requires some configuration. The use-extensions option on the document store component completes the functionality by instructing the document store to generate URLs with the correct filename extension for the document type being generated.
The document store stores documents in conversation scope, and documents will expire when the conversation ends.

At that point, references to the document will be invalid. You can specify a default view to be shown when a document does not exist using the error-page property of the documentStore.
