jakarta.validation.ValidationException: HV000183: Unable to initialize 'jakarta.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead

[Chenramvijay]

I am creating validator in my java application as below

	morphia = new Morphia(new Mapper(options));
	// Configure validator
	new ValidationExtension();

using this version in my build.sbt - "dev.morphia.morphia" % "morphia-validation" % "2.4.13",

getting error in class - dev.morphia.validation.ValidationExtension

this class also have error for interface methods implementation

[evanchooly]

did you include the validation implementation dependencies? morphia only depends on the API for build purposes but you have to declare implementation dependencies in your project that provide the underlying functionality.

yes , I have below libraries in my build.sbt

`"org.mongodb" % "mongodb-driver-sync" % "4.9.0",
"org.mongodb" % "mongodb-driver-legacy" % "4.9.0",
"dev.morphia.morphia" % "morphia" % "2.4.2",
"dev.morphia.morphia" % "entityscanner-plug" % "1.6.1",
"dev.morphia.morphia" % "logging-slf4j" % "1.6.1",
"dev.morphia.morphia" % "morphia-validation" % "2.4.13",

"jakarta.validation" % "jakarta.validation-api" % "3.1.0",
"org.hibernate.validator" % "hibernate-validator" % "8.0.1.Final",
"jakarta.el" % "jakarta.el-api" % "4.0.0",
"org.glassfish" % "jakarta.el" % "4.0.2" % "test",

[Chenramvijay]

Do I need to add any other dependencies?

[evanchooly]

the hibernate validator should do the trick though I'm not sure about the version
