The solution I want to demonstrate is not restricted to JSF, but as I’m developing Java / Web front-ends, I’m rotating in this circle… So, let’s start. First, we need a proper converter to receive URL parameters in JSON format and converts them back to Java. PrimeFaces Extensions...
"Flip the first bit to makeorder by uuidsame asorder by uuid::varchar" When an UUID is read from a result set, JDBC driver flips the MSB again to get back the original UUID in Java. This bit-flipping logic was missing when an UUID was passed from Java as a bind variable. The prop...
Reference data type parameters, such as objects, are also passed into methodsby value. This means that when the method returns, the passed-in reference still references the same object as before.However, the values of the object's fieldscanbe changed in the method, if they have the proper ...
In the pass by reference mechanism, when parameters are passed to the methods, the calling method returns the changed value of the variables to the called method. The call by reference mechanism is not used by Java for passing parameters to the methods. Rather it manipulates objects by referenc...

Step 2: Create before-class and after-class methods that help in getting the browser and closing it when done. Step 3: Create a data provider that actually gets the values by reading our Excel sheet. Step 4: Create a Test that takes different parameters, i.e, Name, Description, Weight,...
I have made a RMI server and client Software that works if the one calls remote methods that have as parameters simple Objects. More precisely: by simple objects I mean the parameters passed to the remote methods are made of classes where the members are all simple primitive data types. ...
so the value of the variable in the function member and the value of the reference parameter will always be the same. Reference parameters need therefmodifier as part of both the declaration and the invocation - that means it's always clear when you're passing something by reference. Let's...
