jndi in java

Java Learning -- What is JNDI and java what is jndi I once remembered that when I was working on the data center charging system, I came into contact with the API. Because of its powerful functions, I didn't know much about it, so I was so worried. Now, we can see that it is actually a group of interfaces. As long

The use of Jndi in the Java EE environment is very simple, because all of the Java-EE containers to implement Jndi service, so, in the Java EE environment using Jndi, and the use of Hashtable is not much different. There is only o

Generally, If you create a connection by yourself, use the followingCodeGet the data source object: Context context = new initialcontext (); Datasource = (datasource) Context.

Java Naming and directory interfaces are a group of APIS for accessing naming and directory services in Java applications. It provides developers with universal and unified interfaces for searching and accessing various naming and directory services. JDBC is built on the abstraction layer. The naming service associates the name with the object and can use the name to access the object. Directory Service is

The overall understanding of Jndi: Jndi (Java naming and directory Interface) it provides a set of interfaces that use naming and directory services. It allows users to use naming and directory services. Just like JDBC. Jndi includes both the naming service and the directory service, where the directory service contai

I remember in the computer room charge system when it came into contact with the API, because it is very powerful function, but it is not very understanding of it, so at that time is also love and afraid. Now, all the way to understand, in fact, it is a set of interfaces. As long as we get to know it, we'll find that it's not as scary as it really is. Today, let's look at the interface--jndi in Java.

The first step is to make it clear that to get a weblogic connection you have to rely on the weblogic associated jar, Not weblogic.jar on the Internet, if you put Weblogic.jar in your classpath is not enough, because the Java class file can not find errors such as [caused by: Weblogic.security.subject.AbstractSubject Java.lang.noclassdeffounderror:weblogic/security/subject/abstractsubject] exception. So what do we do, in fact, it's very simple. Enter

Jndi is primarily used to configure certain resources in a container so that all projects can be used.Jndi can provide:1: Database connection pool.Custom connection PoolingThird-party connection poolingDbcpC3p0Jndi2: Mail server definition.3: Load arbitrary classes so that all projects can be used.jndi:[defined in the Tomcat container, all items must be found in a way that retrieves the service Javax.naming.Context environment (ENV) context.It's one o

To describe JNDI, for example, when obtaining a data source, the JNDI address can be written in either of the following ways:A: Java: COMP/ENV/jdbc/testdsB: JDBC/testds The configuration methods are also different. The first method is a method that facilitates program transplantation or migration. Its implementation is the same as the concept of "ing, method B is

To interact with WebLogic Server, the Java client must be able to obtain the object reference of a remote object and call operations on the object. To complete this operation, the client application code must perform the following steps: 1. Set the JNDI environment attribute of initialcontext. Listing 3-1 describes how to use the context. initial_context_factory attribute and context. provider_url attribute
