The MarkLogic Java Client

The MarkLogic Java Client makes it easy to write, read, delete, and find documents in a MarkLogic database. The client requires connecting to a MarkLogic REST API app server and is ideal for applications wishing to build upon the MarkLogic REST API.

The client supports the following core features of the MarkLogic database:

Write and read binary, JSON, text, and XML documents.
Query data structure trees, marked-up text, and all the hybrids in between those extremes.
Project values, tuples, and triples from hierarchical documents and aggregate over them.
Patch documents with partial updates.
Use Optimistic Locking to detect contention without creating locks on the server.
Execute ACID modifications so the change either succeeds or throws an exception.
Execute multi-statement transactions so changes to multiple documents succeed or fail together.
Call Data Services by means of a Java interface on the client for data functionality implemented by an endpoint on the server.

The client can be used in applications running on Java 8, 11, and 17. If you are using Java 11 or higher and intend to use JAXB, please see the section below for ensuring that the necessary dependencies are available in your application's classpath.

QuickStart

To use the client in your Maven project, include the following in your pom.xml file:

<dependency>
    <groupId>com.marklogic</groupId>
    <artifactId>marklogic-client-api</artifactId>
    <version>6.4.1</version>
</dependency>

To use the client in your Gradle project, include the following in your build.gradle file:

dependencies {
    implementation "com.marklogic:marklogic-client-api:6.4.1"
}

Next, read The Java API in Five Minutes to get started.

Including JAXB support

As of the 7.0.0 release, the client now depends on the Jakarta XML Binding API instead of the older JAXB API. If you are using Java 11 or higher, you no longer need to declare additional dependencies in order to use Jakarta XML Binding. If you wish to use the older JAXB APIs - i.e. those in the javax.xml.bind package instead of jakarta.xml.bind - you are free to include those as dependencies in your application; they will not conflict with the 7.0.0 release of the Java Client.

JAXB support in 6.x releases and older

If you are using Java Client 6.x or older and also Java 11 or higher, and you wish to use JAXB with the Java client, you will need to include JAXB API and implementation dependencies as those are no longer included in Java 11 and higher.

For Maven, include the following in your pom.xml file:

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.2</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-core</artifactId>
    <version>2.3.0.1</version>
</dependency>

For Gradle, include the following in your build.gradle file (this can be included in the same dependencies block as the one that includes the marklogic-client-api dependency):

dependencies {
    implementation "javax.xml.bind:jaxb-api:2.3.1"
    implementation "org.glassfish.jaxb:jaxb-runtime:2.3.2"
    implementation "org.glassfish.jaxb:jaxb-core:2.3.0.1"
}

You are free to use any implementation of JAXB that you wish, but you need to ensure that you're using a JAXB implementation that corresponds to the javax.xml.bind interfaces.
