You can combine the FOP and SVG processes to generate complete reports. Scalable Vector Graphics is a markup lan... (more)

The Perfect Database Round-Trip Using JAXB & JDO

Java Data Objects (JDO) enables Java developers to perform database transactions from within Java objects without writing database (SQL)- or JDBC-specific code. Java Architecture for XML Binding (JAXB) and JDO provide great APIs for performing complex XML- and database-oriented tasks. But what about using the two in tandem? This article is about combining these technologies to solve the complex tasks of data access and data persistence. Java classes can be generated by compiling XML Schemas using JAXB technology. As long as a schema is a well-formed XML document with a definition ... (more)

This article discusses how XML and Formatting Objects Processor (FOP) technology can be used to address this problem. The FOP initiative is a part of ... (more)
