active record vs DAO in persistence layer
main argument against using DAO: the fact that it requires a significant amount of repetitive source code to be produced for no immediate advantage over using JDBC or EJB directly. For many developers, this disadvantage is good enough reason to ignore the long-term benefits of using a framework-neutral API, especially where there are strict project deadlines. Without the code generation advantages of FireStorm/DAO, it is not easy to justify to a project manager or project sponsor the time and cost of manually writing DAO design pattern code, regardless of any future benefits they may see.

Active record claim to be simple, which it encapsulate persistence into its object, and may implement with Rapid development tool like Spring Roo.

solution:
Create a file named /tmp/android.rules with the following contents (hex vendor numbers were taken from the vendor list page):
SUBSYSTEM=="usb", ATTRS{idVendor}=="0bb4", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0e79", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0502", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0b05", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="413c", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0489", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="091e", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0bb4", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="24e3", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="2116", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0482", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="17ef", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="1004", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="22b8", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0409", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="2080", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0955", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="2257", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="10a9", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="1d4d", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0471", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="04da", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="05c6", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="1f53", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="04dd", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0fce", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="0930", MODE="0666" SUBSYSTEM=="usb", ATTRS{idVendor}=="19d2", MODE="0666"Run the following commands:

javax.xml.transform.TransformerException: java.io.FileNotFoundException
Writing xml to file while using java Transformer, having error below:
javax.xml.transform.TransformerException: java.io.FileNotFoundException
Environment: Ubuntu
Reason: Not sure.
I’d tested in both Maven tomcat and Standalone Tomcat 7, only occurred in Standalone Tomcat 7.
Sample code >
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.ENCODING, JRReportStyle.DEFAULT_ENCODING);
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(anOutputFile);
transformer.transform(source, result);
Solution:
Change to use URI – getPath instead of just passing File object into StreamResult.
eg. StreamResult result = new StreamResult(anOutputFile.toURI.getPath());
