[ JBPM 5.2.@ ] web management console crashed but there is a solution – Business Process Management

Dear *,

Recently, I tried the JBPM 5.2.0 – JBoss Business Process Management – web management console and I had an application crash when I selected in the left menu the item “Process overview”.

Fortunately there is a solution to that problem which is to add the following line in the part of the build.xml file included in jbpm-installer_5.2.0 directory :

<!– Install reporting AS7 –>
<target name=”install.reporting.into.jboss7″ depends=”check.birt.as7″ if=”birt.download” >
<mkdir dir=”${install.home}/birt”/>
<unzip src=”${install.home}/lib/birt-runtime-${birt.version.as7}.zip”
dest=”${install.home}/birt”/>
<copy todir=”${install.home}/target/jbpm-gwt-console-server-war/WEB-INF/lib”>
<fileset dir=”${install.home}/birt/birt-runtime-${birt.version.as7}/ReportEngine/lib”>
<include name=”*/.jar”/>
<exclude name=”**/org.apache.commons.codec_1.3.0.v201101211617.jar”/>
</fileset>

[JBoss Data Grid] When Database is very expensive.

Dear *,

Picture 1:

Imagine you have developed a successful web application built on traditional architecture which is visited by a consequent amount of users.

However, you are victim of you success, and more and more users are connected to you site.

Now, you are confronted to the overload of your application and your users tend to be unhappy due to the bad response time of your application.

Picture 2 :

So, in  order to fix this you decided to change your application a little bit and then add some cache to it.

During a certain period of time, that clever trick worked. But, you still had the same problem.

Picture 3 :

Well, you had then the idea to increase the number of Application Servers to resolve that problem.

Nonetheless, with that decision you had to complexity your application.  Nevermind, you had to increase the performance otherwise you were going to lose your customers.

Picture 4:

But the problem still remained and you are now convinced the bottleneck is related to you old heavy database.

So you have no other choice than buy another database licence and its annual maintenance fees.

The MAJOR problem here is that is very very expensive.

Picture 5 :

Anyway, you decide adding more databases is not your only option.
You finally decide to implement a data grid in your environment in order to fix that problem without exploding your allocated budget.

If you are interesting by the subject  then I am going to do a presentation/introduction about “JBoss Data Grid” in Belgium in April 2012.
If your company or you are based in BeNeLux and are interested by this presentation, just let me know and I will try to arrange a meeting for you.

N.B.: JBoss Data Grid 6 beta provides:

• A schema-less key value store: Red Hat JBoss Data Grid 6 beta is a NoSQL data store that provides flexibility to store any type of data.
• Compatibility with many types of applications: JBoss Data Grid 6 beta works with applications written in Java, C#, Spring, and others; deployed in an application server or standalone.
• Reliable grid-based data storage: Red Hat JBoss Data Grid 6 beta is designed to easily distribute data across multiple nodes. Data can be replicated in memory, written to disk, or stored in a relational database for fault-tolerance.
• Elastic scaling: JBoss Data Grid 6 beta allows simple addition and removal of storage nodes without disruption.
• Multiple access protocols: Red Hat JBoss Data Grid 6 beta provides easy access to the data grid using REST, memcached, Hot Rod, or simple map-like API.

[JBoss] JBoss AS7 | EAP6 + Seam 3 + Maven 3 on Fedora 16

Dear *,

Recently I looked for Seam 3 applications running into JBoss AS7 (foretaste purpose) or EAP 6 (Professional use purpose).
So I uncompressed the following packages into a temporary directory (Test purpose) of a common|standard user of the system :

• JBoss EAP6 Beta – Server which provides software applications with services such as security, data services, transaction support, load balancing, and management of large distributed systems. – -> Download Package
• JBoss AS7 – Server which provides software applications with services such as security, data services, transaction support, load balancing, and management of large distributed systems. -> Download Package
• Seam 3 – Seam is a powerful open source development platform for building rich Internet applications in Java. – -> Download Package
• Maven 3.0.3 -> well, if you are using Fedora or RHEL, be root on your system and run “yum install maven”. If not, then go to http://maven.apache.org to install the application

Then I set the JBOSS_HOME directory with the path of my application server – Here I chose to use JBoss EAP6 Beta : export JBOSS_HOME=/home/user/jboss-eap-6.0 (you can set it definitively in the maven settings.xml file or in you local profile).

I ran the JBoss EAP6 Beta Application Server in standalone mode with the following command :

jboss-eap-6.0/bin/standalone.sh

I opened the seam-3.1.0.Final/examples directories to set the following stanza in the pom.xml file :

<plugins>

<plugin>
<groupId>org.jboss.as.plugins</groupId>
<artifactId>jboss-as-maven-plugin</artifactId>
<version>7.1.1.Final</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>deploy</goal>
</goals>
</execution>
</executions>
</plugin>

</plugins>

Finally, I choose one of the Seam 3 examples, went to the corresponding directory and  I compiled and deployed it to the running  JBoss EAP6 Beta application server with the following commands :

cd seam-3.1.0.Final/examples/seam-booking

mvn package jboss-as:deploy

and then went to the following URL : http://localhost:8080/seam-booking

[Deltacloud] Presentation @ FOSDEM’12 – Saturday February 4th, 2012 – 15:00-15:25 – Brussels

Dear all,

Again an interesting talk. This one will be about DeltaCloud API.

Michal Fojtik will be presenting in Virtualization and Cloud Devroom on  Saturday 2012-02-04

15:00-15:25 Open Clouds with Deltacloud API   (room : Chavane)

Here is the abstract :

Start an instance on an internal cloud, then with the same code start another on EC2 or Rackspace. Deltacloud protects your apps from cloud API changes and incompatibilities, so you can concentrate on managing cloud instances the way you want. Deltacloud API prosper from natural open-source evolution and use community driven API design instead of vendor enforced one.

[BoxGrinder] Presentation @ FOSDEM’12 – Saturday February 4th, 2012 – Brussels

Dear all,

BoxGrindier is going to be present @ FOSDEM’12.

Marek Goldmann will be presenting in the JBoss.org dev room on Saturday:

11:00 – 11:55 BoxGrinder : Grind your appliances easily

Here is the abstract :

BoxGrinder is a set of tools that help you grind out appliances: preconfigured disk images with the operating system and requisite software ready to run on a selected virtualization platform. With a simple text definition file and a single command BoxGrinder will build a lean appliance from scratch, convert it to a target format, and deliver it to your chosen infrastructure.

Virtualization has become almost ubiquitous in modern scalable infrastructures, with traditional dedicated hardware setups being replaced by multi-tenanted virtual environments. This change facilitates many of the beneficial properties of Cloud Computing, key amongst which is the ability to create small, function-specific appliances that enables system components to scale independently.

BoxGrinder addresses the key problem of specifying and building such appliances. It manages complexities such as software installation, dependency resolution and remote service interactions on your behalf. Existing methods can an arduously convoluted, with poor repeatability and performance characteristics; wasting time and resulting in slow and bloated appliances.  Such factors negate many of the motivating factors for embracing Cloud computing, and this is an obstacle that BoxGrinder is specifically designed to overcome. Coherent and simple to specify and run; yet fast to build and easily customized to any desired level of complexity.

In this session we will cover the basic concepts of BoxGrinder, with discussion of techniques and use-cases that illustrate how best to utilise BoxGrinder’s powerful feature-set. Finally, we will work through a live example, from text definition to a running virtual appliance.

[FOSDEM'12] Openshift + AS7 Demonstrations @ JBoss.org Booth

Dear all,

Yesterday and in addition of the allocated JBoss.org devroom,  I had the confirmation JBoss.org has get a booth @ FOSDEM’12.

So, I can confirm we are going to do several AS7 application deployment demonstrations over the cloud without having to worry about downloading and managing the stack, writing scripts or installing agents in using Openshift.
