Using Spring IoC allows to set bean properties exposed via setters: public class Bean { private String value; public void setValue(String value) { this.value = value; } } And the bean definition is: <bean class="Bean"> <property name="value" value="Hello!"> </bean> Is there any existing plugins/classes for Spring Framework that allows to directly expose bean fields as properties without defining setters? Something like this with the same bean definition: public class Bean { @Property private String value; } You can: use the @Value annotation and inject a property (using expression language)

Hi can i configure gson that he use int instead of double got data like: {fn: chat, data: {roomId: 1, text: "Some brabble"}} I got a PacketClass to deserialize it to: public class DataPacket { private String fn; private Object p; // will be a StringMap } and decode like: DataPacket pkg = gson.fromJson(message, DataPacket.class); for better typehandling i got a data pojo for the DataPacket.p field for example: public class ChatPacket { public int roomId; public String message; public String from; // getter & setter } to parse the data to the packet i use BeanMaps like (i removed error handling

For example, I have this code: <jsp:useBean id="dog" class="Dog" scope="application"> <jsp:setProperty name="dog" property="breed" value="House Dog !!!"/> </jsp:useBean> I know how it works. But, sometimes, I change some some code in this, for example: "dog" to "newDog", I will meet error or unguested-result (with me). Please give me how above code is generated into Java. (maybe just a main idea) Thanks :) JSPs ultimately get generated to .java classes which get compiled as servlets. Check the server's work folder. In case of Tomcat, a /test.jsp gets generated as /org/apache/jsp/test_jsp.java

Today I'd like to know some features on the JSF Lifecycle. Let me start : 1 - Phase 2:Apply request Values - During this phase,each component in the view will search for its values in the request and set the new values to them Uhm, ok nice. So, the View will be built due to the previous Beans parameters. After, there is a partial View, generated with the request values. (Right? Later, in the 3° phase, they will be compared) . But, for example, if a values in the request list is absent during the creation of this last view? Values will be null? 2 - Phase 5: Invoke Application - Once all the

I'm obtaining an information about a class via Introspector.getBeanInfo(this.getClass()).getPropertyDescriptors() then getting the property's name by invoking propery[i].getName() . Everything is fine if a property has no one-letter-part. For example, if a property has a name personAddress (meanwhile its getter/setter -> getPersonAddress() , setPersonAddress(String personAddress) ), is's OK, getName() returns personAddress . But if the property has a name rPersonId ( getRPersonId() , setRPersonId(Long rPersonId) ) then getName() returns "RPersonId", i.e. first letter has been capitalized! Why?
