I'm trying to run below commands as per the guide:
java -cp .;target/RTSDKJ_Maven-1.0-jar-with-dependencies.jar com.refinitiv.ema.provider.IProvider
java -jar ./target/RTSDKJ_Maven-1.0-jar-with-dependencies.jar
But both commands throws class not found exception. When I checked inside the jar file, I couldn't find the specific classes as well.
Can anyone help me to find how to run these commands?

Hello @hanhuitan
If your source code directory is based on the EMA Java source code like the following example.
Your pom.xml setting must be matched this directory structure as follows:
<build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-assembly-plugin</artifactId> <executions> <execution> <phase>package</phase> <goals> <goal>single</goal> </goals> <configuration> <archive> <manifest> <mainClass> com.refinitiv.ema.examples.training.consumer.series100.ex100_MP_Streaming.Consumer </mainClass> </manifest> </archive> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> </configuration> </execution> </executions> </plugin> </plugins> </build>
Then you need to run the single-all-dependencies jar file with the following classpath
java -cp .;target/RTSDKJ_Maven-1.0-jar-with-dependencies.jar com.refinitiv.ema.examples.training.iprovider.series100.ex100_MP_Streaming.IProvider java -jar ./target/RTSDKJ_Maven-1.0-jar-with-dependencies.jar
Hello @hanhuitan
The project above is based on the How to Set Up Refinitiv Real-Time SDK Java Application with Maven article, but you need to change the source code to the EMA Java example one.
Another practical step-by-step guide to set up an EMA Java examples project with Maven is the How to Set Up Real-Time SDK Java Application with Maven on the Eclipse IDE article.
As I said earlier, the RTSDK Java is available with Gradle-based by default. However, you can submit a change request to the product team via the https://my.refinitiv.com/content/mytr/en/feedback.html page.
Hello @hanhuitan
It seems the RTSDKJ_Maven-1.0-jar-with-dependencies.jar file does in included the Dependencies classes.
How did you build the jar? I am assuming that you are using Maven, did you set Maven to build a single-all-dependencies jar file in the pom.xml file?
You can find an example in the "Building the project" section of the How to Set Up Refinitiv Real-Time SDK Java Application with Maven article.
Please note that the classpath in a <manifest> tag must match the source code directory.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> ... <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-assembly-plugin</artifactId> <executions> <execution> <phase>package</phase> <goals> <goal>single</goal> </goals> <configuration> <archive> <manifest> <mainClass><Main Class></mainClass> </manifest> </archive> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> </configuration> </execution> </executions> </plugin> </plugins> </build> </project>
Hello @hanhuitan
Which version of the EMA API you are using?
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>com.refinitiv.ema</groupId>
<artifactId>ema</artifactId>
<version>${rtsdk.version}</version>
</dependency>
Hope this helps.
Hi,
Can I get a maven example project instead of Gradle?
Hello @hanhuitan
The RTSDK Java is currently available with Gradle-based by default. However, you can submit a change request to the product team via the https://my.refinitiv.com/content/mytr/en/feedback.html page.
