Suppose that I have an email field annotated with:
@NotEmpty(message="Please enter email address") ...Bean validation will trigger two errors when no email address is entered: the email field is empty an empty email field is not a valid email address Displaying both errors to the user with <form:errors> would be redundant and confusing:

My problem is simple: in my XML data, a timestamp is provided as a long integer (number of milliseconds since the "the epoch"). When I do XSLT, I want to display it as a readable string, such as "Mon Nov 01 18:08:48 CDT 2010". After hours of struggle, I found: It's not so easy to get the job done with JDK 1.6 There are tons of garbage on the web in this space (suggestions, code snippets that simply don't work) Simple Xalan extension functions was the only resource that's somewhat informative. Even there some of the examples don't work. Below is a list of what worked and what didn't. This works:

The Android unit test framework is based on JUnit 3 , not JUnit 4. Test cases have to extend junit.framework.TestCase or a subclass (such as android.test.InstrumentationTestCase ). Tests are identified by public methods whose name starts with test , not methods annotated with @Test (as in JUnit 4). An Android test suite is packaged as an APK, just like the application being tested. To create a test package, first you need to identify the application package it is testing. Google suggests to put the test package source in a directory named tests/ alongside the src/ directory of the main application. At runtime, Android instrumentation loads both the test package and the application under test into the same process. Therefore, the tests can invoke methods on...

This is an odd-ball content provider in that it doesn't provide database records, but provides a resource as a stream. It can be used to provide media files or XML resources. Start the project with:

PostgreSQL provides two distinct ways to store binary data: Binary data can be stored in a table using the data type bytea . By using the Large Object feature which stores the binary data in a separate table in a special format and refers to that table by storing a value of type oid in your table. Different methods are used to access the BLOBs depending on which storage type you choose: To use the bytea data type you should use the getBytes() , setBytes() , getBinaryStream() , or setBinaryStream() methods. To use the Large Object functionality you can use either the LargeObject class provided by the PostgreSQL JDBC driver, or by using the getBLOB() and setBLOB() methods. Using setBinaryStream on an OID column yields...

This error happens when the ordering of elements in web.xml is not correct. For example, in a <servlet> declaration, <servlet-name> should come before <servlet-class> . If you switch the order of <servlet-name> and <servlet-class> , you'll get this error. This was my stack trace in JBoss when I declared <load-on-startup> before <init-param> for a servlet:

This runtime error happens when the Sun EL implementation is not available. Look for the class com.sun.el.ExpressionFactoryImpl in your deployment package, you probably won't find it, or you'll find a version that can't be loaded in your deployment environment. If you are using Maven to build, you can add the following repository and dependency in pom.xml :
