Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    javax.el.ELManager.getExpressionFactory(ELManager.java:38)

The following method did not exist:

    'javax.el.ExpressionFactory javax.el.ELUtil.getExpressionFactory()'

The method's class, javax.el.ELUtil, is available from the following locations:

    jar:file:/root/workflow/emos-workflow.jar!/BOOT-INF/lib/el-api-2.2.jar!/javax/el/ELUtil.class

    jar:file:/root/workflow/emos-workflow.jar!/BOOT-INF/lib/jakarta.el-3.0.3.jar!/javax/el/ELUtil.class

The class hierarchy was loaded from the following locations:

    javax.el.ELUtil: jar:file:/root/workflow/emos-workflow.jar!/BOOT-INF/lib/el-api-2.2.jar!/

Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.el.ELUtil
