RTFTemplate is RTF to RTF engine, which is enable to merge RTF model (Template) with data comming from JAVA object (Context). RTFTemplate can generate RTF document, which is the result of merge of RTF model and data.
To use RTFTemplate you must :
After merge step, merge fields (MERGEFIELD) and hyperlink (HYPERLINK) will be replaced by your data comming from your JAVA context. Bookmarks (BOOKMARK) are used to set start/end loop of a list which contains JAVA objects (ex : to generate for instance a RTF table (RTF rows) by iterating on this thist).
To start using RTFTemplate, you can go to user guide.
RTFTemplate generation process is executed with 3 steps :
Result of this step give a new RTFDocument which contains macro of the selected template engine.
You can find here a schema which explains RTFTemplate process generation.
Here a RTF model sample designed with MS Word :
After merge of RTF model with context (JAVA object), RTF target document obtained is :
Here JAVA code used to obtain the last RTF target document :
String rtfSource = "usecases/models/jakartavelocityproject/jakarta-velocity-model.rtf"; String rtfTarget = "jakarta-velocity-model.rtf.rtf"; // 1. Get default RTFtemplateBuilder RTFTemplateBuilder builder = RTFTemplateBuilder.newRTFTemplateBuilder(); // 2. Get RTFtemplate with default Implementation of template engine (Velocity) RTFTemplate rtfTemplate = builder.newRTFTemplate(); // 3. Set the RTF model source rtfTemplate.setTemplate(new File(rtfSource)); // 4. Put the context rtfTemplate.put("project", new Project("Jakarta Velocity project")); rtfTemplate.put("header_developer_name", "Name"); rtfTemplate.put("header_developer_email", "Email"); rtfTemplate.put("header_developer_roles", "Roles"); List developers = new ArrayList(); Developer developer = new Developer("Will Glass-Husain", "email@example.com"); developer.addRole("Java Developer"); developer.addRole("Release Manager"); developers.add(developer); rtfTemplate.put("developers", developers); ... List dependencies = new ArrayList(); Dependency dependency = new Dependency("commons-collection", "jar", "1.0", "http://jakarta.apache.org/commons/collection/"); dependencies.add(dependency); rtfTemplate.put("dependencies", dependencies); ... // 5. Merge the RTF source model and the context rtfTemplate.merge(rtfTarget);
ATTENTION this sample is not the optimal strategy of RTFTemplate using. If you have performance constraint, go to the section how optimize RTFTemplate?
Before 1.0.1-b8 version RTFTemplate was based only on Velocity template engine. Today RTFTemplate can be configured with Spring XML file. Now you can implement your template engine or redefine existing implementation of template engine as you want.

The new API is able to separate the different steps of generation process of RTFTemplate. Each step can be too implement as you want.
