A Java array is a Java object. The length of an array is fixed. Only data of the same type can be stored in the same array. An array can store data of the basic type, you can also store reference data. When creating an array object, you must specify the length of the array object. Once an array is created, its length cannot be changed. (1) When creating an array object (when a new array is created), you mus

", properties={"connectionAttributes=;create=true"} ) The name property value of the data source is the JNDI name to be bound. According to the characteristics of JNDI, this value should be unique. From the above example, we can note that the first part of the attribute value, that is, java: app is a namespace description. The Application Component namespace is introduced in JavaEE 6. Currently, the following namespaces can be used:
