Hi,
I want to access the JNDI Directory context in Tomcat8. I've used
*DirContextURLStreamHandler* class which was in Tomcat 7. But now that
has been removed.
Can someone tell me how can I access the JNDI Directory Context in
Tomcat 8?
Via the standard JNDI API.
Mark
Can you elaborate a little? For this example:
public static void main(String[] args) {
try {
// Gets the JNDI context
Context jndiContext = new InitialContext();
// Looks up the administered objects
ConnectionFactory connectionFactory = (ConnectionFactory)
jndiContext.lookup(jms/javaee7/ConnectionFactory);
Destination queue = (Destination) jndiContext.lookup(jms/javaee7/
Queue);
// Sends a text message to the queue
try (JMSContext context = connectionFactory.createContext()) {
context.createProducer().send(queue, Text message sent at
+ new Date());
}
} catch (NamingException e) {
e.printStackTrace();
}
}

how can that be modified to load the jndi.properties file?
thanks,

The javadoc for InitialContext seems to indicate that this file will be processed automatically. If it isn't processed automatically, I'd suggest trying to figure out why. Good to know, thank you. Amazingly, this is the only Java example code I've ever seen which, potentially, enables remote JNDI lookup for JMSContext. -Thufir - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
loading properties file from WEB-INF instead of WEB-INF/classes
getPropsFromWebINF works so long as the properties file is within the package of
the class (/. However, I'd like to put the properties file under WEB-INF:
public void getPropsFromWebINF() throws IOException {
Properties p = new Properties();
InputStream is;
is = getClass().getResourceAsStream(sqljdbc4.properties);
p.load(is);
log(p.toString());
}
I've seen mention of using:
System.getenv(APP_PROPERTIES);
in conjunction with a context (context.xml under META-INF) along the lines of:
?xml version=1.0 encoding=UTF-8?
Context antiJARLocking=true path=/A00720398sat
Environment name=APP_PROPERTIES
description=The APP Properties File override=false
type=java.lang.String
value=/WEB-INF/app.properties /
/Context
however, I'm not able to get the environment, I just get a null value.
What's the correct, and simple, idiom? (Staying away from jndi and dbcp for
now, and, oddly enough, servlets in this case.)
Actually, I suppose in a sense it's in WEB-INF:
dtc01l0376-06:~ a00720398$
dtc01l0376-06:~ a00720398$ jar -tfv
NetBeansProjects/A00720398sat/dist/A00720398sat.war | grep sql
498 Sat Apr 17 14:36:14 PDT 2010
WEB-INF/classes/controller/sqljdbc4.properties
however, I'd like to move it from WEB-INF/classes up to just WEB-INF.
thanks,

JNDI config
For a servlet to employ JNDI to access a JDBC database, Tomcat must be configured? JNDI won't work on a vanilla configuration of Tomcat? 1. Install Your JDBC Driver Use of the JDBC Data Sources JNDI Resource Factory requires that you make an appropriate JDBC driver available to both Tomcat internal classes and to your web application. This is most easily accomplished by installing the driver's JAR file(s) into the $CATALINA_HOME/lib directory, which makes the driver available both to the resource factory and to your application. http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html Thanks, Thufir - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Also, just to clarify, if I'm using toplink for JPA then the toplink jars, and whatever I'm using for jdbc, need to be copied to tomcat as per: http://wiki.netbeans.org/DeployREST2Tomcat55 (instead of derby I'm using mssql.jar) thanks, Thufir - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

From Netbeans I've installed the Tomcat plug-in, which seems to have resulted in two Tomcat directories: /usr/share/tomcat5.5 /usr/share/tomcat5.5-webapps When I go to create a new web application from the IDE, Netbeans prompts for the user/password for a manager and the path to Catalina. Which version of Tomcat are they referencing? Do I need to install Tomcat 5.5 from Ubuntu, or just the plug-in from Netbeans? Just not quite sure how to get started.
