dx-magnolia-ocm is a library which integrates Jackrabbit OCM with Magnolia CMS

dx-magnolia-ocm doesn't depend on Magnolia, allowing to read and write Magnolia Jackrabbit storage from external applications

Contents

Advantages over Jackrabbit OCM
  • More polished API
  • Generic type safety
  • Magnolia content and node data collections are supported
  • Magnolia mgnl:resource type is supported
  • 1 to 1 mapping of OCM beans and JCR types is not required
  • Enums are fully supported, enum type is detected by field type
Getting started

Download library:
dx-magnolia-ocm-1.0.1.jar
dx-magnolia-ocm-1.0.1-sources.jar

Install it into your Maven repository:

call mvn install:install-file -DgroupId=com.devexperts.web -DartifactId=dx-magnolia-ocm -Dversion=1.0.1 -Dpackaging=jar -Dfile=dx-magnolia-ocm-1.0.1.jar -DgeneratePom=true
call mvn install:install-file -DgroupId=com.devexperts.web -DartifactId=dx-magnolia-ocm -Dversion=1.0.1 -Dpackaging=jar -Dclassifier=sources -Dfile=dx-magnolia-ocm-1.0.1-sources.jar -DgeneratePom=false

You may also put this library into external repository instead of local one.

Note: the library is going be published to publicitly available Maven repository soon, making these steps reduntant. Stay tuned.

Add the following dependency to your Maven project:

<dependency>
<groupId>com.devexperts.web</groupId>
<artifactId>dx-magnolia-ocm</artifactId>
<version>${dx-magnolia-ocm.version}</version>
</dependency>

Specify packages where OCM bean classes are searched. Add the following JVM parameter:

-Dcom.devexperts.ocm.packages=<comma separated list of packages> 

Now you can use this library in your code.

Creating OCM beans

All bean classes must inherit com.devexperts.ocm.BaseOCM class.
Also they must be placed in packages specified by com.devexperts.web.packages system property.

dx-magnolia-ocm uses the same rules as Jackrabbit OCM does. See

Example bean class:
@Node(jcrType = BaseOCM.MGNL_CONTENT_NODE_TYPE) 
public class FinancePlan extends BaseOCM {
    public enum PricingModel {
        FREE, PAID
    }

    @Field 
    private String name;
    @Field
    private PricingModel pricingModel;
    @Field(jcrDefaultValue = "false")
    private boolean active;
    @Bean
    private Money price;

    public FinancePlan() {}

    public PricingModel getPricingModel() {
        return pricingModel;
    }

    public void setPricingModel(PricingModel pricingModel) {
        this.pricingModel = pricingModel;
    }

    public boolean isActive() {
        return active;
    }

    public void setActive(boolean active) {
        this.active = active;
    }

    public boolean getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Money getPrice() {
        return price;
    }

    public void setPrice(Money price) {
        this.price = price;
    }

}

Note the following:

  • The class is inherited from BaseOCM class which contains path and uuid fields. 
  • JCR type is explicitly specified. By default, nt:unstructured type is used, so the type should be specified in most cases.
  • Each field and bean has its own getter and setter.
  • You may specify default values for fields.
  • Enum is supported as field type.
