This is like saying, sitting in a classroom in medical school is useless because they are not showing how to do operations there!



Certifications make sure you read the chapter on files and threads and nio and lambda properly. Which you many not do otherwise

)

OK but it gets tricky when you have components that are singleton and components that are not

Any "Strategy" of how they can work well with each other?

By default when I use @Component annotation spring creates only singleton object?

Are there design patterns that go beyond a mickey mouse example that I can use where I can have objects with state?

In your project use Tomcat server,

1. Just click Service in netbeans -> open Tomcat - Right click the project - Choose undeploy option

In your project use glassfish server

1. Just click Service in netbeans -> open GlassFisf - Right click the project - Choose undeploy option

This is how I solved it

I use createEjbContainer api without passing properties

look for your temp folder, it creates a glassfish 3 temp domain there

checkin that folder structure under src/test/resources/gfv3

this is what i have

src\test\resources\gfv3 src\test\resources\META-INF src\test\resources\gfv3\domains src\test\resources\gfv3\lib src\test\resources\gfv3\domains\domain1 src\test\resources\gfv3\domains\domain1\config src\test\resources\gfv3\domains\domain1\config\admin-keyfile src\test\resources\gfv3\domains\domain1\config\cacerts.jks src\test\resources\gfv3\domains\domain1\config\cadump.txt src\test\resources\gfv3\domains\domain1\config\domain.xml src\test\resources\gfv3\domains\domain1\config\keyfile src\test\resources\gfv3\domains\domain1\config\keystore.jks src\test\resources\gfv3\domains\domain1\config\login.conf src\test\resources\gfv3\domains\domain1\config\server.policy src\test\resources\gfv3\lib\install src\test\resources\gfv3\lib\install\applications src\test\resources\gfv3\lib\install\applications\jaxr-ra src\test\resources\gfv3\lib\install\applications\jmsra src\test\resources\gfv3\lib\install\applications\__cp_jdbc_ra src\test\resources\gfv3\lib\install\applications\__dm_jdbc_ra src\test\resources\gfv3\lib\install\applications\__ds_jdbc_ra src\test\resources\gfv3\lib\install\applications\__xa_jdbc_ra src\test\resources\gfv3\lib\install\applications\jaxr-ra\jaxr-ra.jar src\test\resources\gfv3\lib\install\applications\jmsra\fscontext.jar src\test\resources\gfv3\lib\install\applications\jmsra\imqbroker.jar src\test\resources\gfv3\lib\install\applications\jmsra\imqjmsbridge.jar src\test\resources\gfv3\lib\install\applications\jmsra\imqjmsra.jar src\test\resources\gfv3\lib\install\applications\jmsra\imqjmx.jar src\test\resources\gfv3\lib\install\applications\jmsra\imqstomp.jar src\test\resources\gfv3\lib\install\applications\__cp_jdbc_ra\__cp_jdbc_ra.jar src\test\resources\gfv3\lib\install\applications\__dm_jdbc_ra\__dm_jdbc_ra.jar src\test\resources\gfv3\lib\install\applications\__ds_jdbc_ra\__ds_jdbc_ra.jar src\test\resources\gfv3\lib\install\applications\__xa_jdbc_ra\__xa_jdbc_ra.jar src\test\resources\META-INF\persistence.xml


Then you can edit domain.xml add datasources there

then use code to test ejb

I used glassfish v3, maven, oracle db

Map<String, Object> p = new HashMap<String, Object>(); // p.put(EJBContainer.APP_NAME, "TON_APP_NAME"); File[] modules = { new File("target/test-classes"), new File("target/classes") }; p.put(EJBContainer.MODULES, modules); p.put("org.glassfish.ejb.embedded.glassfish.installation.root", "src/test/resources/gfv3"); ejbContainer = EJBContainer.createEJBContainer(p); ctx = ejbContainer.getContext(); ejbFacade = (AllocnGrpFacade) ctx.lookup("java:global/classes/AllocnGrpFacade");


and test

@Test public void testFindAll() throws Exception { final List<AllocnGrp> all = ejbFacade.findAll(); assertNotNull(all); for (AllocnGrp allocationGroup : all) { System.out.println(allocationGroup); } }

this is how the config looks

<?xml version="1.0" encoding="UTF-8"?> <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> <persistence-unit name="ACP-warPU" transaction-type="JTA"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> <jta-data-source>jdbc/acp</jta-data-source> <exclude-unlisted-classes>false</exclude-unlisted-classes> <shared-cache-mode>ALL</shared-cache-mode> <properties> <property name="eclipselink.target-database" value="org.eclipse.persistence.platform.database.oracle.Oracle11Platform"/> <property name="eclipselink.logging.level" value="FINE"/> <property name="eclipselink.logging.timestamp" value="true"/> <property name="eclipselink.logging.thread" value="true"/> <property name="eclipselink.logging.logger" value="ServerLogger"/> </properties> </persistence-unit> </persistence>

good luck

I was reading some article and someone said A | B, A ^ B, A ^ B swaps variables without tempraroay 3rd var

but it doesnt, you have to use 3 XORs

package test; public class SwapEm { public static void main(String[] args) { System.out.println(Integer.MAX_VALUE); swapPlus(Integer.MAX_VALUE-1,2); swapXOR(Integer.MAX_VALUE-1,2); } private static void swapXOR(int i, int j) { i = i | j; j = i ^ j; i = i^ j; System.out.println(i); System.out.println(j); System.out.println(".."); } private static void swapPlus(int i, int j) { i = i+j; j = i-j; i = i-j; System.out.println(i); System.out.println(j); System.out.println(".."); } }

If you use datasources, jee server would "know" and manage transactions for you

if you use DriverManager api, the container wont know that you are creating a connection and it wont enlist/manage those connections

something lot of people forget and run into trouble

Does this help?

if you find maven learning curve too steep

you could use ANT with ivy
