Running CLUSTERED Broadleaf Ecommerce 1.5.0 Demo in Oracle GlassFish Server 3.1.1

Once you have Broadleafdemo running in Oracle Glassfish 3.1.1 (read http://lydonchandra.blogspot.com/2011/12/running-broadleaf-ecommerce-150-demo-in_26.html), you might want to run it in a clustered Glassfish configuration using Apache 2.2 + mod_jk connector.

Most of the instructions below are obtained from http://tiainen.sertik.net/2011/03/load-balancing-with-glassfish-31-and.html
1. From Glassfish admin, create a new cluster, say cluster1

2. Once cluster1 is created, go to Instances tab, and create 2 new instances, instance1 and instance2

3. Create mod_jk listener, go to Configurations > Network Config > Network Listener , and click on New.
3a. Enter "mod-jk" on Name textbox,
3b. enter 28009 as port number and
3c. make sure you check the JK Listener checkbox. Click Save.
3d. Stop and start the cluster

4. Download Apache 2.2 and mod_jk (http://tomcat.apache.org/download-connectors.cgi), extract Apache 2.2 and mod_jk.so into Apache22/modules directory

5. Add the following to Apache httpd.conf


Include conf/mod-jk.conf

6. create conf/mod-jk.conf

LoadModule jk_module modules/mod_jk.so

 

# Where to find workers.properties

JkWorkersFile conf/workers.properties

# Where to put jk logs

JkLogFile logs/mod_jk1.log

 

# Set the jk log level [debug/error/info]

JkLogLevel info 

 

# Select the log format

JkLogStampFormat  "[%a %b %d %H:%M:%S %Y]"

 

# JkOptions indicates to send SSK KEY SIZE

JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

 

# JkRequestLogFormat

JkRequestLogFormat "%w %V %T"

               

# Mount your applications

JkMountFile conf/uriworkermap.properties               

# Add shared memory.

# This directive is present with 1.2.10 and

# later versions of mod_jk, and is needed for

# for load balancing to work properly

JkShmFile logs/jk.shm 

              

# Add jkstatus for managing runtime data

    JkMount status

    Order deny,allow

    Deny from all

    Allow from 127.0.0.1

7. Create worker.properties with the following information, put the correct ip address on worker.node1.host

worker.node1.port=28009

worker.node1.host=127.0.0.1

worker.node1.type=ajp13

worker.node1.lbfactor=1

worker.status.type=status

worker.loadbalancer.sticky_session=1

worker.loadbalancer.type=lb

worker.loadbalancer.balance_workers=node1

worker.list=loadbalancer,status

8. Create uriworkermap.properties to tell mod_jk which webapp to mount

/=loadbalancer

/*=loadbalancer

/broadleafdemo=loadbalancer

/broadleafdemo/*=loadbalancer

9. Start httpd

Running Broadleaf Ecommerce 1.5.0 Demo in Oracle GlassFish Server 3.1.1

Once you got it deployed and running in JBoss 7 (read my previous post http://lydonchandra.blogspot.com/2011/12/running-broadleaf-ecommerce-150-demo-in.html)

you can just use the same broadleafdemo.war (which has modified compass JAR) and

deploy it as an Web-Application from the GlassFish Server administration page > Applications > Deploy

Running Broadleaf Ecommerce 1.5.0 Demo in JBoss 7.1.0.CR1b

A bit more complicated as it should be in the beginning, where JBoss changes the protocol name from vfszip to vfs,

1. so I had to build the latest Compass trunk (rev 3940) from http://svn.compass-project.org/svn/compass/trunk/

2. Modify http://svn.compass-project.org/svn/compass/trunk/src/main/src/org/compass/core/config/binding/scanner/ScannerFactoy.java

to:

else if ( url.getProtocol().equals("vfszip") || 

url.getProtocol().equals("vfs") ) {

            url = new URL(urlString);

            return new JarScanner(basePackage, url.openStream(), filter);

        }

3. Replaced the broadleaf's supplied compass-2.2.0.jar with the newly built Compass jar file ( available from http://www.multiupload.com/AY0F7UPKX6 as of Dec 25 2011)

4. Start JBoss (in standalone mode), everything should work fine!!

Running Broadleaf eCommerce Demo 1.5.0 in JBoss 5.1

I had problems deploying Broadleaf eCommerce Demo 1.5.0 in JBoss 7.0. So I went back to JBoss 5.1 and followed this forum post and finally got the broadleafdemo.war to deploy in JBoss 5.1.

Why JBoss you ask ? Well some enterprise users use JBoss and we want to give them an easier option to deploy inside their JBoss app server, rather asking them to install Tomcat or run from Jetty.

If they have to install Tomcat or run from Jetty, then they will have to configure their network security settings etc etc, it's just not fun. So why JBoss again ? To make deployment easier, for now at least :)

Steps:

1. Download and extract JBoss 5.1 if you haven't already, and make sure you can run broadleaf with mysql as your database (follow my previous post about running broadleaf with mysql or google it).

2. Remove jboss-5.1.0.CR\common\lib\hibernate-validator.jar (or move it somewhere else)

3. Copy the expanded broadleafdemo.war to jboss-5.1.0.CR\server\default\deploy

4. Download compass-2.3.1-beta1.jar from either java2s.com or rutgersmaps and replace broadleafdemo.war\WEB-INF\lib\compass-2.2.0.jar

5. Start JBoss, and you should be able to access http://myserver:8080/broadleafdemo

Running Broadleaf E-commerce demo in Various Java Application Server and Database

First we start using MySQL and Tomcat 7.0

1. Extract broadleafdemo.war file into an expanded war
2. As detailed here in http://www.broadleafcommerce.org/forum/viewtopic.php?f=9&t=379



2a. in META-INF/persistence-demo.xml' file replace 
- org.hibernate.dialect.HSQLDialect by org.hibernate.dialect.MySQLDialect in the 'blPU' and 'blSecurePU' persistence unit configurations

2b. in WEB-INF/applicationContext-demo.xml' file replace the following lines 


<bean id="webDS" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
      <property name="driverClassName" value="org.hsqldb.jdbcDriver" />
      <property name="url" value="jdbc:hsqldb:mem:broadleaf;ifexists=false" />
      <property name="username" value="sa" />
      <property name="password" value="" />
   </bean>


with


<bean id="webDS" class="org.apache.commons.dbcp.BasicDataSource"
      destroy-method="close">

      <!-- The JDBC Driver class name. -->
      <property name="driverClassName" value="com.mysql.jdbc.Driver" />
      <property name="url" value="jdbc:mysql://localhost:3306/broadleaf" />
      <property name="username" value="MY_USER_NAME" />
     <property name="password" value="MY_PASSWORD" />
   </bean>






and update the username and password properties accordingly!!!


3. login to mysql and create database 'broadleaf'


mysql>> create database broadleaf;


4. copy the expanded broadleaf.war directory created in #1 above into Tomcat 7.0 directory


5. download & copy mysql-connector-java-5.1.17.jar into broadleafdemo.war/WEB-INF/lib


6. start tomcat.




Caveat:


For some reason Spring Framework complains about NOT finding the com.mysql.jdbc.Driver ?
However the broadleafdemo site works OK.

Reading big file quickly by skipping

This is to read a grid file with columns such as
a1 b1 c1
a2 b2 c2
a3 b3 c3
a4 b4 c4
a5 b5 c5
a6 b6 c6
a7 b7 c7
a8 b8 c8
a9 b9 c9
a10 b10 c10


say we want to read 'approximately' every 4 lines, i.e. line2 then line6 and then line10, then what we can do is
to jump using the file offset. As we only want to read a 'whole' line and we can't guarantee  whether a line is 'whole' or not if we use the file offset, we read and then discard a line, and read the next one. This assumes a line is separated by newline.


read line and discard
read line and save //a2 b2 c2
jump 27bytes ahead //a line is approx 9bytes with a newline
read line and discard
read line and save //a6 b6 c6
jump 27bytes ahead
read line and discard
read line and save //a10 b10 c10
...


     using boost::iostreams::position_to_offset;
     using boost::iostreams::seek;
     using boost::iostreams::stream_offset;

     stream_offset off;

         // save EOF offset so we know if we have finished reading the file
     stream_offset endoff = position_to_offset(seek(in, 0, BOOST_IOS::end));
     // go back to beginning of file, we have gone to EOF in line above     seek(in, 0, BOOST_IOS::beg);
     string line2;
     while( true ) {
                 // first read, we get "incomplete line", so ignore it
         getline(in, line2);

                 // second read, we get "complete" line
         getline(in, line2);
         //cout << line2 << endl;

                 // jump approximately 1000 lines ahead
         off = position_to_offset(seek(in, 200000, BOOST_IOS::cur));

                 // finish reading the file
         if( off > endoff ) {
             break;
         }
     }

     cout << "finished" << endl;

Java Object Size

To get the object size, YourKit Profiler v9.0.2 is used and for SimpleClass, shallow sizes are used.

public class SimpleClass {
public int x;
}
For 32bit Java, the size of the object is 16 bytes.
For 64bit Java, size is 24 bytes

public class SimpleClass {
public int x;
public int y;
}
32bit Java -> 16 bytes.
64bit Java -> 24bytes.

public class SimpleClass {
public int x;
public int y;
public int z;
}
32bit Java -> 24 bytes.
64bit Java -> 32 bytes.
