<LearnWLS> How to setup Weblogic official sample - EJB

1. Download weblogic installer from www.oracle.com

2. Install Weblogic

$ sudo xhost + # in case current user cannot access Xwindow
access control disabled, clients can connect from any host

$ java -jar fmw_12.2.1.0.0_wls.jar

# it needs full installation with samples
# then weblogic isinstalled at $ORACLE_HOME/wlserver
# and the samples isat $ORACLE_HOME/wlserver/samples
# btw, for more details please reference to index.html under
$ORACLE_HOME/wlserver/samples/server

3. Create a Weblogic domain

$ cd $ORACLE_HOME/oracle_common/common/bin
$ sh config.sh #configuration wizard

# create a domain by default at $ORACLE_HOME/user_projects/domains/base_domain

4. Start the domain

$ cd $ORACLE_HOME/user_projects/domains/base_domain
$ startWebLogic.sh &     # start domain

URL - http://localhost:8001/console/
5. Customize example properties

$ cd $ORACLE_HOME/wlserver/samples/server/examples/src
$ vi examples.properties

# for example:
<bea.home=@BEA_HOME
<wl.home=@WL_HOME
---
>bea.home=/home/weblogic/orahome # ORACLE_HOME
>wl.home=${bea.home}/wlserver
13,14c13,14
<wls.hostname=@SERVER_HOST
<wls.port=@LISTEN_PORT
---
>wls.hostname=localhost
> wls.port=8001
16,17c16,17
<wls.username=@DOMAIN_USERNAME
<wls.password=@DOMAIN_USER_PASSWORD
---
>wls.username=scott
>wls.password=tiger000
22c22
<examples.home.dir=@WL_HOME/samples/server/examples
---
>examples.home.dir=${wl.home}/samples/server/examples

6. Prepare data forDerby

$ cd $ORACLE_HOME/wlserver/samples/server
$ . ./setExamplesEnv.sh # set environment variables

$ cd examples/common/ddl
$ ant db.setup.derby    # Generating Derby Data

7. Define Data source in console

Name -examples-demoXA
JNDI Name - examples-dataSource-demoXAPool
Database Type - Derby
Database Driver - Derby's Driver (Type 4 XA) Versions: Any

8. Define Messaging

JMS Servers - examplesJMSServer

JMS Modules - examplesJMSModule

# then define resources under the module
1) Queue
Name- weblogic.examples.ejb30.ExampleQueue
JNDI Name - weblogic.examples.ejb30.ExampleQueue
2) ConnectionFactory
Name - weblogic.examples.ejb30.QueueConnectionFactory
JNDI Name - weblogic.examples.ejb30.QueueConnectionFactory

Note:
A Subdeployment is needed for Queue and Connection Factory, however, I always encounter
following issues, so I have to use a workaround: create 2 Subdeployments respectively for them.
>>>>>
weblogic.management.configuration.ServerMBeanImpl cannot be cast to weblogic.management.configuration.JMSServerMBean
<<<<<
or

>>>>>
TheSubDeploymentMBean examplesSub in deployment examplesJMSModule canonly be targeted to one JMSServerMBean because an entity that canonly be targeted to a single JMS server (for example
a queue, topicor quota) has a sub-deployment-name element with value examplesSub
<<<<<

9. Prepare EJB sample

$ cd $ORACLE/wlserver/samples/server/examples/src/examples/ejb/ejb30
$ ant build
$ ant deploy

10. Run the sample
