Cannot use javax.script.ScriptEngine for JavaScript when Camunda 7.16.7-ee is installed

Camunda 7 Topics Discussion & Questions
1

Hello,
For a task, I am upgrading the Camunda version (from 7.11.21-ee) to 7.16.7-ee deployed in JBOSS EAP Version 7.3.9.GA. There is an application running on this JBOSS which uses javax.script.ScriptEngine for their usecase. The scriptEngine in use there is JavaScript.

Once I perform update to Camunda 7.16.7-ee , the Javascript scriptEngine isnt available for the said application (this is not seen with 7.11.21-ee). Does anyone have encountered this before?

jdk version: 1.8.0_333

Dependency for application as below:

<dependency>
            <groupId>org.camunda.bpm</groupId>
            <artifactId>camunda-engine</artifactId>
            <scope>provided</scope>
</dependency>

I have already gone through the below links but my problem seems to be slightly different (I am not deploying any .bpmn workflow) :

Thanks,
Sharath

Dependencies for javax as below:

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>${version.javax.javaee}</version>
        <scope>provided</scope>
    </dependency>

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-web-api</artifactId>
        <version>${version.javax.javaee}</version>
    </dependency>

Please let me know if any other info is required.

Thanks,

Hi @sharath07,

I suspect that the jboss server didn’t use Java 1.8, as there is a JavaScript engine included.

Please double check the log files when starting the server.

For me it starts with

as I’m running Java 17.

Hope this helps, Ingo

Hi @Ingo_Richtsmeier,
Thanks for your reply! I cross checked the java version again and it as seen below:

java.runtime.name = Java™ SE Runtime Environment

java.runtime.version = 1.8.0_333-b31
java.vendor = Oracle Corporation
java.vendor.url = http://java.oracle.com/
java.vendor.url.bug = http://bugreport.sun.com/bugreport/
java.version = 1.8.0_333

I added dependencies for GraalVM JS (recommended solution for JDK 15) and it seems to have solved the problem.

Thanks,
Sharath
