So to enable the JS or the CSS servlet, you must at least define a bundle of the specified type. So if you configure only JS bundle, the plugin will start only the Jawr JS servlet. The configuration will indicate to the plugin which Jawr servlet to start. All jawr packages start with net.jawr.*, so you can use that as a key for an appender. Jawr uses sl4j to log messages, so you can configure its tracing level along with the rest of your application. If you add none of the jawr.css.* parameters, for instance, Jawr will do no effort to serve CSS files. Note that you are not forced to use Jawr for both js and css files. Using this syntax, you will be able to define bundles as specified in the relevant documentation pages.
To configure Jawr you must add properties to the oovy file located at the /conf folder of your application.

This will result in an img tag with a src attribute of a suitable data uri. They all take a single argument, bytes, which is a byte containing the raw bytes of the images. The tags are under the namespace rendering and are called inlinePng, inlineGif and inlineJpeg. To make this easier, the plugin provides tags to render byte arrays as common image formats (i.e. Using inline images, you can include the image bytes in the document to be rendered.

This plugin adds support for inline images via data uris This is useful for situations where the images you need to imbed in a rendered PDF or image are generated by the application itself.įor example, your application may generate barcodes that you don't necessarily want to expose but want to include in your generated PDFs or images. This means that the Content-Length header will not be set unless you manually specify the length via the contentLength property to the render method. This copy can be avoided and the render (or bytes) can be written directly to the response output stream. This is so the number of bytes can be determined and the Content-Length header set (this also applies when passing the bytes directly). When rendering to the response, the content is first written to a temp buffer before being written to the response. New File( "coupon.jpg").withOutputStream. ĭef bytes = gifRenderingService.render(template: '/images/coupon', model: ) Be sure to declare the XHTML doctype at the start of your GSP like so. Without a doctype, you are likely to get parse failures due to unresolvable entity references (e.g. If it does not, a .XmlParseException will be thrown. The GSP must render to well formed, valid, XHTML. The rendering engine resolves all relative links relative to the rverURL config property. Depending on your network config in production, this may require some special consideration. This is due to the linked resources being accessed by application and not a browser. images, css) must be accessible by the application. There are a few things that you do need to be aware of when writing GSPs to be rendered via this plugin.Īll links to resources (e.g.
