Spring Util Map Annotation with Enum key

-

I wanted create java.util.Map in spring context xml file which injects the Map to one of my service class, but i was struggling with this because my Map's key is an enum value, Finally I was able fix that issue as following, in Spring we can specify the key-type and value-type specifically with generics values. That part was the interesting and new part i found time. All it goes as follows.


<map
     key-type="EnumType">
        <entry key="ENUM_VALUE"  value-ref="leastLoadedAssignmentMechanism" />
</map>

PostgreSQL bytea and oid

-
I came across with following issue when i'm trying to save the uploaded file in to the database as a byte array using hibernate, JPA 2.0  annotation with Postgre SQL. even though in this stage i'm pretty much new to Postgre SQL, It has two type of data types to represent the binary data or BLOB, since i'm using hibernate jpa annotations use the annotation @Lob to indicate the byte[] of data to persist as a binary data. @Lob   @Basic(fetch = FetchType.LAZY)  public byte[] getPicture() { return picture;  }    exception : java.sql.SQLException: ERROR: column "picture" is of type bytea but expression is of type oid   Then i understood the issue with the data types.but when the hibernate generating the table it creates the  column with data type "oid" , after removing this annotation it creates a table column with "bytea" data type. and i'm in doubt which would be the most suitable data type to use.   Then i found the difference...

1. Introduction Microservices is not a new term. It coined in 2005 by Dr Peter Rodgers then called micro web services based on SOAP. It became more popular since 2010. Micoservices allows us to break our large system into number of independent collaborating processes. Lets see below microservices architecture. 1.1 What is Microservices Architecture? Microservices architecture allows to avoid monolith application for large system. It provide loose coupling between collaborating processes which running independently in different environments with tight cohesion. So lets discuss it by an example as below. For example imagine an online shop with separate microservices for user-accounts, product-catalog order-processing and shopping carts. So these components are inevitably important for such a large online shopping portal. For online shopping system we could use following architectures. 1.2 Shopping system without Microservices (Monolith architecture) In this architecture we are ...

Adding MySQL datasource to JBOSS AS 7

-
Retrieve the MySQL Connector The connector can be downloaded from:  http://dev.mysql.com/downloads/connector/j/ . The current version at the time of writing is 5.1.24, further sections of this guide assume that version number. Unzip the connector to your downloads folder and save the location of the main JAR in a variable which we can refer to later: Add a Module to AS 7 AS 7 uses a module system to provide isolation in class loading. We need to create a new module which contains the MySQL Connector J JAR. Move to the the AS installation directory and create the folder structure for the new module: export JBOSS_HOME =~ / Development / jboss-as-web-7.0.0.Final cd $JBOSS_HOME mkdir -p modules / com / mysql / main Copy the driver jar to the new directory and move to that directory: cp MYSQL_JAR $JBOSS_HOME / modules / com / mysql / main cd $JBOSS_HOME / modules / com / mysql / main Define the module in XML. This is the key part of the process....
