To ensure that the Java Invoke static connector in a Mule 4 application can access a static method in a dependency jar file, you need to make the dependency visible to the connector's class loader. Here are the two effective methods to achieve this:
* Using Maven Command:
* Include Dependency via Maven: Add the dependency jar file using Maven when packaging the Mule application. This ensures that the jar file is included in the application's build and is available at runtime.
* Add the dependency to your pom.xml file:
<dependency> <groupId>com.example</groupId> <artifactId>example-library</artifactId>
<version>1.0.0</version> </dependency>
* Use the Maven package command to build the application and include the dependency:
mvn clean package
* Configuring Dependency as a Shared Library:
* Shared Library Configuration: Configure the dependency as a shared library in the project POM.
This makes the jar available to all components within the Mule application.
* Define the shared library in pom.xml:
xml
<dependency> <groupId>com.example</groupId> <artifactId>example-library</artifactId>
<version>1.0.0</version> <scope>provided</scope> </dependency>
* Steps for Java Invoke Configuration:
* Ensure the static method in the dependency jar file is accessible via the Java Invoke connector by correctly configuring the connector with the class and method details.
* Benefits:
* Maven Integration: Using Maven ensures that the dependency management is streamlined and integrated with the build lifecycle of the Mule application.
* Shared Library: Configuring as a shared library ensures that the dependency is managed centrally and is easily accessible by various parts of the Mule application.
