Every image loader plug-in has a hard-coded usage penalty that influences which solution is chosen if there are multiple possibilities to load an image. Sometimes, though, these penalties need to be tweaked and this can be done in the FOP configuration. An example:
<fop version="1.0"></p>
<p>The second penalty element sets an "infinite" penalty for the TIFF loader using the internal TIFF codec. This practically disables that plug-in as it will never be chosen as a possible solution.</p>

For each run, create a new org.apache.fop.apps.Fop instance through one of the factory methods of FopFactory. In the method call you specify which output format (i.e. MIME type) to use and, if the selected output format requires an OutputStream, which OutputStream to use for the results of the rendering. You can customize FOP's behaviour in a rendering run by supplying your own FOUserAgent instance. The FOUserAgent can, for example, be used to set your own document handler instance (details below). Finally, you retrieve a SAX DefaultHandler instance from the Fop object and use that as the SAXResult of your transformation.</p>

It's also easy to comment out the FOP part for debugging purposes, for example when you're tracking down a bug in your stylesheet. You can easily write the XSL-FO output from the XSL transformation to a file to check if that part generates the expected output.

<p>Logging is now a little different than it was in FOP 0.20.5. We've switched from Avalon Logging to <a href="http://commons.apache.org/logging/">Jakarta Commons Logging</a> . While with Avalon Logging the loggers were directly given to FOP, FOP now retrieves its logger(s) through a statically available LogFactory. This is similar to the general pattern that you use when you work with Apache Log4J directly, for example. We call this "static logging" (Commons Logging, Log4J) as opposed to "instance logging" (Avalon Logging). This has a consequence: You can't give FOP a logger for each processing run anymore. The log output of multiple, simultaneously running FOP instances is sent to the same logger.</p>
<p>By default, <a href="http://commons.apache.org/logging/">Jakarta Commons Logging</a> uses JDK logging (available in JDKs 1.4 or higher) as its backend. You can configure Commons Logging to use an alternative backend, for example Log4J.

<p>The use of "feedback" instead of "logging" is intentional. Most people were using log output as a means to get feedback from events within FOP. Therefore, FOP now includes an <code>event</code> package which can be used to receive feedback from the layout engine and other components within FOP <strong>per rendering run</strong> . This feedback is not just some text but event objects with parameters so these events can be interpreted by code. Of course, there is a facility to turn these events into normal human-readable messages. For details, please read on on the <a href="events.html">Events page</a> . This leaves normal logging to be mostly a thing used by the FOP developers although anyone can surely activate certain logging categories but the feedback from the loggers won't be separated by processing runs. If this is required, the <a href="events.html">Events subsystem</a> is the right approach.</p>

The output (XSL-FO) from the XSL transformation is piped through to FOP using SAX events. This is the most efficient way to do this because the intermediate result doesn't have to be saved somewhere. Often, novice users save the intermediate result in a file, a byte array or a DOM tree. We strongly discourage you to do this if it isn't absolutely necessary. The performance is significantly higher with SAX.</p>

It's an example that shows how an arbitrary Java object can be converted to XML. It's an often needed task to do this. Often people create a DOM tree from a Java object and use that. This is pretty straightforward. The example here, however, shows how to do this using SAX, which will probably be faster and not even more complicated once you know how this works.
<figure alt="Example Java object to XML" src="images/EmbeddingExampleObj2XML.png"></figure>
For this example we've created two classes: ProjectTeam and ProjectMember (found in xml-fop/examples/embedding/java/embedding/model). They represent the same data structure found in xml-fop/examples/embedding/xml/xml/projectteam.xml. We want to serialize to XML a project team with several members which exist as Java objects. Therefore we created the two classes: ProjectTeamInputSource and ProjectTeamXMLReader (in the same place as ProjectTeam above).</p>
<p>The XMLReader implementation (regard it as a special kind of XML parser) is responsible for creating SAX events from the Java object. The InputSource class is only used to hold the ProjectTeam object to be used.</p>
<p>Have a look at the source of ExampleObj2XML.java to find out how this is used. For more detailed information see other resources on JAXP (ex. <a href="http://java.sun.com/xml/jaxp/dist/1.1/docs/tutorial/xslt/3_generate.html">An older JAXP tutorial</a> ).</p>

<p>In versions until 0.20.5, Apache™ FOP used <a href="http://excalibur.apache.org/framework/index.html">Avalon-style Logging</a> where it was possible to supply a logger per processing run. During the redesign the logging infrastructure was switched over to <a href="http://commons.apache.org/logging/">Commons Logging</a> which is (like Log4J or java.util.logging) a "static" logging framework (the logger is accessed through static variables). This made it very difficult in a multi-threaded system to retrieve information for a single processing run.</p>
<p>With FOP's event subsystem, we'd like to close this gap again and even go further. The first point is to realize that we have two kinds of "logging". Firstly, we have the logging infrastructure for the (FOP) developer who needs to be able to enable finer log messages for certain parts of FOP to track down a certain problem. Secondly, we have the user who would like to be informed about missing images, overflowing lines or substituted fonts. These messages (or events) are targeted at less technical people and may ideally be localized (translated). Furthermore, tool and solution builders would like to integrate FOP into their own solutions. For example, an FO editor should be able to point the user to the right place where a particular problem occurred while developing a document template. Finally, some integrators would like to abort processing if a resource (an image or a font) has not been found, while others would simply continue. The event system allows to react on the
se events.</p>
<p>On this page, we won't discuss logging as such. We will show how the event subsystem can be used for various tasks. We'll first look at the event subsystem from the consumer side. Finally, the production of events inside FOP will be discussed (this is mostly interesting for FOP developers only).</p>

<p>To simplify event production, the event subsystem provides the <code>EventProducer</code> interface. You can create interfaces which extend <code>EventProducer</code> . These interfaces will contain one method per event to be generated. By contract, each event method must have as its first parameter a parameter named "source" (Type Object) which indicates the object that generated the event. After that come an arbitrary number of parameters of any type as needed by the event.</p>
<p>The event producer interface does not need to have any implementation. The implementation is produced at runtime by a dynamic proxy created by <code>DefaultEventBroadcaster</code> . The dynamic proxy creates <code>Event</code> instances for each method call against the event producer interface. Each parameter (except "source") is added to the event's parameter map.</p>
<p>To simplify the code needed to get an instance of the event producer interface it is suggested to create a public inner provider class inside the interface.</p>

<p>Inside an invocation handler for a dynamic proxy, there's no information about the names of each parameter. The JVM doesn't provide it. The only thing you know is the interface and method name. In order to properly fill the <code>Event</code> 's parameter map we need to know the parameter names. These are retrieved from an event object model. This is found in the <code>org.apache.fop.events.model</code> package. The data for the object model is retrieved from an XML representation of the event model that is loaded as a resource. The XML representation is generated using an Ant task at build time ( <code>ant resourcegen</code> ). The Ant task (found in <code>src/codegen/java/org/apache/fop/tools/EventProducerCollectorTask.java</code> ) scans FOP's sources for descendants of the <code>EventProducer</code> interface and uses <a href="http://qdox.codehaus.org/">QDox</a> to parse these interfaces.</p>
<p>The event model XML files are generated during build by the Ant task mentioned above when running the "resourcegen" task. So just run <code>"ant resourcegen"</code> if you receive a <code>MissingResourceException</code> at runtime indicating that <code>"event-model.xml"</code> is missing.</p>
<p>Primarily, the QDox-based collector task records the parameters' names and types. Furthermore, it extracts additional attributes embedded as Javadoc comments from the methods. At the moment, the only such attribute is "@event.severity" which indicates the default event severity (which can be changed by event listeners). The example event producer above shows the Javadocs for an event method.</p>
<p>There's one more information that is extracted from the event producer information for the event model: an optional primary exception. The first exception in the "throws" declaration of an event method is noted. It is used to throw an exception from the invocation handler if the event has an event severity of "FATAL" when all listeners have been called (listeners can update the event severity). Please note that an implementation of <code>org.apache.fop.events.EventExceptionManager$ExceptionFactory</code> has to be registered for the <code>EventExceptionManager</code> to be able to construct the exception from an event.</p>
<p>For a given application, there can be multiple event models active at the same time. In FOP, each renderer is considered to be a plug-in and provides its own specific event model. The individual event models are provided through an <code>EventModelFactory</code> . This interface is implemented for each event model and registered through the service provider mechanism (see the <a href="#plug-ins">plug-ins section</a> for details).</p>

Before it does that, it consults a (currently hard-coded) registry of glyph substitution groups (see Glyphs.java in Apache XML Graphics Commons). This registry can supply alternative glyphs in some cases (like using space when a no-break space is requested). But there's no guarantee that the result will be as expected (for example, in the case of hyphens and similar glyphs). A better way is to use a font that has all the necessary glyphs. This glyph substitution is only a last resort.</p>
