javabeans

Is there any proper way to override the way JSF accesses the beans fields from an Expression Language? The idea is to mimic this behavior in order to access a Map<String, ?> values, where the bean fields would be the map keys. In other words, is it possible anyhow to use #{beanContainingNestedMap.keyOfSaidNestedMap} , just as if keyOfSaidNestedMap were a field of the beanContainingNestedMap ? If not, what other solution may I have? Example: Holder.java public class Holder { private Map<String, Object> objects = new HashMap<String, Object>(); public void add(String key, Object value) { objects

I have a large number of Java bean classes in my web application, and I am trying to find a simple way to implement the toString() methods in these beans. The toString() method would be used for logging throughout the application, and should print the attribute-value pairs of all attributes in the bean. I am trying out two alternatives: 1. BeanUtils.describe() (Apache commons-beanutils) 2. ReflectionToStringBuilder.toString() (Apache commons-lang) Since this is a web application expected to have high traffic, the implementation has to be lightweight and should not impact performance. (Memory

The JavaBeans methods' signature's has to follow certain conventions such as set.../get... and such.

i have a little trouble in Spring with two component of a service. I have this component: @Component public class SmartCardWrapper and this one: @Component public class DummySmartCardWrapper extends SmartCardWrapper The service autowire both but spring fails due this expection: org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [com.cinebot.smartcard.SmartCardWrapper] is defined: expected single matching bean but found 2: [dummySmartCardWrapper, smartCardWrapper] Why it doesn't use class names? That's one of the most basic concepts of Spring - Inversion of

I just noticed something I didn't know. private boolean isCertified; public boolean isCertified() { return isCertified; } public void setCertified(boolean certified) { isCertified = certified; } The following getters and setters have been generated by Intellij. By the way, Lombok generate the same kind of getters and setters. I would have expected something like: private boolean isCertified; public boolean isIsCertified() { return isCertified; } public void setIsCertified(boolean certified) { isCertified = certified; } That's why I usually don't prefix my boolean attributes with ìs , despites

I've tried to use the Mkyong's guide to access external properties file, without any success. This is my bean definition in web-osgi-context.xml file located in WEB-INF: <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"> <property name="basenames"> <list> <value>classpath:bundles/resource</value> <value>classpath:bundles/override</value> <value>file:c:/test/messages</value> </list> </property> <property name="cacheSeconds" value="10"/> </bean> Accessing the bean: @SpringBean private ReloadableResourceBundleMessageSource messageSource;
