jndi

How can you realize the usage of JNDI , with an example if possible? JNDI is the Java Naming and Directory Interface. It's used to separate the concerns of the application developer and the application deployer . When you're writing an application which relies on a database, you shouldn't need to worry about the user name or password for connecting to that database. JNDI allows the developer to give a name to a database, and rely on the deployer to map that name to an actual instance of the database. For example, if you're writing code that runs in a Java EE container, you can write this to

I have an ldap server that I'm using to authenticate users within a tomcat web application. I'm using the JNDIRealm and it's configured within a context file and this works great. I'll also need to search the ldap for user information. I've figured out how to do this with the "jndi method" and I have it working fine outside of tomcat by creating my own jndi context using a hashtable. However, instead of configuring the jndi properties in code, I'd like to create a JNDI Rsource in my context file right next to the Realm configuration. I'm thinking I would do something like this: <Resource name=

We have a plain standalone spring application and we need to put jdbc datasource in jndi. (we use jboss treecache and it need datasource to be in the jndi). Some googling found most of all jndi-lookup examples with spring, where an object is already put in jndi (by tomcat or application server etc), but we need otherwise: I have a plain datasource Spring bean, which I inject to other services, but I can't inject it to TreeCache, because it needs it only from jndi. Found org.springframework.jndi.JndiTemplate , which can be declared as bean, e.g.: <bean id="fsJndiTemplate" class="org

Why java.sql.Connection cannot be cast to oracle.jdbc.OracleConnection in code below? My main goal is to pass to Oracle connection new user name and save it in 'SESSION' table in for example 'osuser' column because I want to trace in DB user changes and display it in the table. @Repository public class AuditLogDAOImpl implements AuditLogDAO { @PersistenceContext(unitName="myUnitName") EntityManager em; @Resource(name = "dataSource") DataSource dataSource; public void init() { try { Connection connection = DataSourceUtils.getConnection(dataSource); OracleConnection oracleConnection =

Can any one tell or point me to code to list all the jndi entries in a remote machine It is possible to list all entries of an InitialContext. You can use this snippet: InitialContext ctx = new InitialContext(); NamingEnumeration<NameClassPair> list = ctx.list(""); while (list.hasMore()) { System.out.println(list.next().getName()); } If you are using an application server, there is usually the option to browse the JNDI tree. The previous answers didn't give me the "full picture" (on Tomcat7), so I've thrown together the following amalgamation, which converts the JNDI values to a Tree Map (with
