JavaOne and Oracle Open World Community Run - Monday, Oct 1, 6:17am PT

Following the tradition from last year, inviting all JavaOne and Oracle Open World attendees to run with me in one of the 10 best cities to run in the US.

The running route will start at Ferry Plaza on Embarcadero, go through Fisherman's Wharf, straight up Hyde St, couple of loops around Crooked Street and then back the same route to end at Ferry Plaza. Here is the complete clickable map:



The Hyde Street (~300ft in 0.75 miles) and Lombard (~200 ft in 0.15 mile) are challenging elevations and you may cover them once only. Alternatively you may take a simpler route out-and-back by running further up to Marina and Crissy Field.

When ? Monday, Oct 1, 2012

I plan to leave at 6:17am PT from the starting point and certainly hope you can join me.

Oracle is doing several things to keep Oracle Open World and JavaOne sustainable and reduce the conference footprint. Lets do our share to keep the conference green!

Of course, don't forget the Geek Bike Ride is tomorrow.

JavaOne and Oracle Develop India 2012 Trip Report


JavaOne and Oracle Develop India 2012 concluded earlier this week. About 2000 attendees for JavaOne makes it the biggest Java developer conference in South Asia. The conference showed Oracle's continued commitment to move Java forward and demonstrated progress on different fronts.

Several attendees told me that they liked Java EE related sessions and how it demonstrated how the platform is making progress. The automatic service provisioning feature was particularly well appreciated. The complete instructions to download the Conference Planner sample showing some PaaS capabilities of the platform is available at glassfish.org/javaone2011. And the video that explains the PaaSing a Java EE application is shown below.



I had several speaking engagements at the conference including Technical Keynote, Meet The Experts, 2 Hands-on Labs, and 2 Technical Sessions.

I helped mentor a hands-on lab that explained how to Develop/Deploy/Monitor a Java EE 6 Application in a GlassFish Cluster. The room was packed with 120 attendees and several folks made good progress by following the instructions in the document. The complete self-paced lab instructions can be downloaded here and the source code here. The lab explains how to create a 2-instance cluster, front-end the cluster with a load balancer, verify that session replication works, and then monitor the application using JavaScript.




The session on GlassFish REST Administration Backend explained the internals of how GlassFish exposes a RESTful API for administration, monitoring, and management. But other than learning internals, the emphasis was more on how to build a large-scale RESTful application. The tips and tricks part of the presentation shared the lessons learned during our exercise of publishing this API. The slides are available:


Do you know the RESTful management API is at localhost:4848/management/domain and the monitoring API is localhost:4848/monitoring/domain. And did you know that you can append ".xml" or ".json" to the RESTful URIs and the data is displayed in the requested format ?

The evening concluded with a dinner with several JUG leaders and Java Champions from all around the world. There was Kevin Nilson from the Silicon Valley JUG, Vinicius and Yara Senger from the SouJava, Stephen Chin from the Java FX User Group, Raj Mahendra from the JUG Chennai, Kayal from JDuchess Chennai, Murali Vallath from AIOUG and several other luminaries. However its still surprisingly shocking that in a country of 1.2 billion+ people, there are only 4 active JUGs - Pune, Bangalore, Chennai, and Nagpur. And then Hyderabad JUG was created at JavaOne India. I plan to write a detailed blog on what it takes to start a JUG any where and hopefully that will motivate some individuals to start more JUGs around the world. Anyway, here are some pictures from the dinner:








Day 2 for me started with Meet The Experts session with Dalibor Topic, Terrence Barr, Michael Heinrichs, and Markus Hirt. The 9am session started low on attendance but the 250+ capacity room was packed within 15 minutes. And the questions ranged from merged JVMs, comparison between HTML5 and JavaFX, NoSQL support in Java EE, JavaFX on mobile, features in JDK 8/9/10, Project Avatar, and all over the Java landscape. The engaged audience kept asking questions all the way to the end.

Then I delivered a session on WebLogic 12c: Developer Deep Dive at Oracle Develop. This session gave an overview of some of the new features that are available in Oracle WebLogic Server 12c such as zip installer (TOTD #174), simplified programming model with Java EE 6, new Maven goals, and extensive IDE support. The slides are available.



A comprehensive Java EE 6 application was explained with a code walk-through and deployed on WebLogic server using NetBeans. TOTD #176 explains how you can deploy this application on WebLogic as well. There are several blogs that explain new Maven support in WebLogic and I've already prepared a blog draft (to be published soon) explaining the same using the TOTD format. There were some cases of Websphere -> WebLogic migration and that is always welcome!

The final session of the day for me was the Java EE 6 Application Development using NetBeans and WebLogic hands-on lab at Oracle Develop. This self-paced guided the attendees to build a complete end-to-end application using different Java EE 6 technologies such as JavaServer Faces 2, Enterprise JavaBeans 3.1, Java Persistence API 2, and Contexts & Dependency Injection. The self-paced lab instructions are available here. I was told that with about 75 attendees this was the most heavily attended lab of Oracle Develop.

The evening concluded with the GlassFish & Friends Party. We've conducted this party at the premier JavaOne event for the past 5 years and this is the first time we've taken it to a regional event. There were about 110+ JavaOne attendees who were present at the party and had some great conversations. Several folks told me that they enjoyed the party and are already looking forward to it next year. The Nagpur JUG had the biggest presence at the party and they are a charged up bunch of folks. I really wish other cities have similar amount of passion and energy as well. Here are some pictures from the party:










On a personal side, the fitness center of Novotel Hotel is pretty good and this allowed me to continue following the Spartacus Workout. A visit to Hyderabad must include a trip to Paradise Biryani and so managed to sneak in that after the GlassFish party. The OTN welcome party was a good way to decompress at the end of Day 1 and got the attendees dancing to the latest bollywood flicks by Vasundhara Das. Here are some pictures from the dance party:






Here are some more pictures captured from the event:












And now the complete album:



Many thanks to the Novotel Hotel and HICC staff, competent technical crew, events team running around for logistics, attendees, local and international speakers, and everybody else. A good conference is a blend of all of these together and JavaOne India certainly had a good mix.

For me, the next stops are Turkey, Poland, Ukraine, Johannesburg ...

Java EE 6 Sample Application on WebLogic 12c: Conference Planner (TOTD #176)


Oracle WebLogic 12c provide a Java EE 6 Full Platform compliant application server. During the launch event last year, a Java EE 6 application was shown that demonstrated all the features of Java EE 6. This application allows conference organizers to publish details about their conference such as tracks, sessions, and speakers. It also allows attendees to register for the conference and prepare their schedule. The application is built as a typical 3-tier Java EE 6 application using JavaServer Faces (with PrimeFaces widgets) for the front-end, Enterprise JavaBeans for the middle tier business logic, and Java Persistence API for connectivity with the database.

This Tip Of The Day (TOTD) shows how to deploy the application on WebLogic 12c.
  1. Check out the application from svn.java.net/svn/glassfish~svn/branches/arun/ConferencePlanner/trunk/ or download the source bundle.
  2. Download and install Apache Derby. If you are using JDK7 then it comes bundled with Derby and installed in directory (/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/db). Any other database can be used as well but the instructions will differ accordingly.
    1. Create "derby.properties" file in the main directory of and specify the following content:

      #
      derby.user.sa=sa

      This creates a user "sa" with the password "sa".
    2. Start the database by invoking the "bin/startNetworkServer" script.
    3. Copy "derbyclient.jar" to "mydomain/lib" directory and restart the server by using "mydomain/startWeblogic.sh" script.
    4. Create and populate the database by invoking the interactive SQL scripting tool "bin/ij". Specify the location of the SQL from the application as shown.
      ./ij
      ij version 10.8
      ij> driver 'org.apache.derby.jdbc.ClientDriver';
      ij> connect 'jdbc:derby://localhost:1527/cp;ServerName=localhost;databaseName=cp;user=sa;password=sa;create=true';
      ij> run '/Users/arungup/code/workspaces/arun/ConferencePlanner/trunk/src/main/sql/javaone-sf-2011.sql';
      ij> . . .
      1 row inserted/updated/deleted
      ij> exit;
  3. Download, unzip, and configure WebLogic 12c as described in TOTD #174. Here is my simple script that performs all the steps required:
    mkdir 12c
    cd 12c
    export CLASSPATH=/Users/arungup/tools/db-derby-10.8.2.2-bin/lib/derbyclient.jar
    unzip ~/Downloads/wls1211_dev.zip export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home ./configure.sh . $MW_HOME/wlserver/server/bin/setWLSEnv.sh cd .. mkdir mydomain cd mydomain $JAVA_HOME/bin/java $JAVA_OPTIONS -Xmx1024m -XX:MaxPermSize=256m weblogic.Server

    Notice, here we are explicitly including "derbyclient.jar" in the  CLASSPATH. This will ensure that Derby database's JDBC driver is available to WebLogic Administration Console which was not able to pick up JAR files from "mydomain/lib" directory otherwise.
  4. Access WebLogic Admin Console at localhost:7001/console, the login/password used in TOTD #174 is admin/admin007.
  5. Create a JDBC data source
    1. Click on "Data Sources" as shown.


    2. Click on "New" and select "Generic Data Source" as shown.

    3. Specify the values as shown.



      The JDBC resource name is "jdbc/cp" and the database is "Derby".
    4. Change the "Database Driver" to "Derby's Driver (Type 4) Versions: Any" and click on "Next". Make sure to not choose Type 4 XA driver which is the default.
    5. Take the defaults and select "Next".
    6. Specify the connection properties as shown.



      And click on "Next".
    7. Click on "Test Configuration" to make sure that every thing is configured correctly. Make sure to see the message "Connection test succeeded.". Verify the defaults and click on "Next".
    8. Select the target "myserver" as shown



      and click on "Finish".
  6. Deploy the application
    1. In the localhost:7001/console, click on "Home" (at the top center) and then "Deployments".


    2. Click on "Install".
    3. Specify the location of the WAR file as shown



      Make sure to pick the WAR file by selecting the radio button and click on "Next".
    4. Take the defaults and click on "Next".
    5. Take the defaults again and click on "Next". Notice that "myserver" is chosen as the target of deployment.
    6. Click on "Finish". After the application is deployed the console shows the following snapshot:


  7. Access the application at localhost:7001/ConferencePlanner to see the output as:



Feel free to browse through the source code!

JavaOne Moscow/Russia Trip Report


JavaOne Moscow/Russia was kick started this morning and followed the usual pattern of a strategy keynote providing an overall strategy of the Java platform, technical keynotes providing more detailed overview of Java SE, JavaFX, Java ME, and Java EE, and then there were hands-on labs and sessions. The big keynote theater was packed with 1300+ audience in the morning and then scattered to different rooms.

The "Develop, Deploy, and Monitor a Java E 6 Application on GlassFish" hands-on lab had about 40+ attendees. The network was a little slow and so it took a long time to download the maven repository. However as I was explaining the Java EE 6 applications, folks started drawing analogies with Spring and realizing how much simpler Java EE 6 has become from its predecessors. An existing Spring user pointed out that "Java EE 6 is much simpler than Spring because of the default conventions and require minimal configuration". Read a more engaged discussion on Why Java EE 6 is better than Spring.



Anyway, the content for the hands-on lab can be downloaded from here. It explains:
  • Walk through a Java EE 6 application
  • Create a 2-instance GlassFish cluster and front-end with a Web server and a load balancer
  • Show session replication when one of the instances fail
  • Use extensible monitoring infrastructure to generate application-specific monitoring data

I also delivered the Java EE Technical Keynote which gave an update on Java EE 7. It also showed a demo of how GlassFish automatically provisions service as part of the initial work in Java EE 7. The complete demo instructions, along with a video are available at glassfish.org/javaone2011.


Here are some pictures captured from the day:














Do you know the man in the last picture on right column ?

You probably will not see him in person. But he is the man who maintains the master JavaOne schedule, besides many other tasks. Its not an easy job as you can imagine :-)

Many thanks to Ralph Crawford for doing an outstanding job for all these years!

And now the complete album:



JavaOne Russia continues tomorrow so make sure you attend the sessions, talk with the speakers, and make the best use of this premier conference in your neighborhood.

For me, next stop is Great Indian Developer Summit!

Running by Moscow River


JavaOne Russia is starting tomorrow! I got in the city early this morning, slept a little but got up early because of jet lag.

New country, new city and how do you get familiar ? Run!

Running would you take you places that you would generally not see otherwise. And the hotel is right by the Moskva River with long empty sidewalks right next to it. Here is how my running route from this morning:


Fortunately, it was not "Moscow cold" and I enjoyed the run. I could've gone longer but had to revert back because of other activities already planned during the day. Here are some pictures captured during the run:








And then some more pictures from around the city ...
