Answer 1

Add the following to your pom.

<dependency>
  <groupId>org.glassfish.web</groupId>
  <artifactId>el-impl</artifactId>
  <version>2.2.6</version>
  <scope>test</scope>
</dependency>

It will resolve the need for javax.el. Current version is 2.2.6

Answer 2

I met the same problem, Add the following dependency resolved this problem.

When you met javax/el/PropertyNotFoundException， That means you missed el-api dependency, you can add the following jar

    <dependency>
        <groupId>javax.el</groupId>
        <artifactId>el-api</artifactId>
        <version>2.2</version>
        <scope>provided</scope>
    </dependency>

or

<dependency>
  <groupId>javax.el</groupId>
  <artifactId>javax.el-api</artifactId>
  <version>3.0.0</version>
  <scope>test</scope>
</dependency>

Then you met ClassNotFoundException:com.sun.el.ExpressionFactoryImpl , You missed el-impl jar:

<dependency>
  <groupId>org.glassfish.web</groupId>
  <artifactId>el-impl</artifactId>
  <version>2.2</version>
  <scope>test</scope>
</dependency>

Answer 3

You maybe just need to add the dependency in your test. Are you using maven? if so, can you try to add this to your pom? You may need a different jar/version, but something like this:

<dependency>
  <groupId>javax.el</groupId>
  <artifactId>javax.el-api</artifactId>
  <version>3.0.0</version>
  <scope>test</scope>
</dependency>

Answer 4

I haven't el-impl in my pom.xml

 <dependency>
                <groupId>javax.servlet</groupId>
                <artifactId>servlet-api</artifactId>
                <version>2.5</version>
                <scope>provided</scope>
            </dependency>
            <dependency>
                <groupId>javax.servlet.jsp</groupId>
                <artifactId>jsp-api</artifactId>
                <version>2.2</version>
                <scope>provided</scope>
            </dependency>
            <dependency>
                <groupId>javax.servlet</groupId>
                <artifactId>jstl</artifactId>
                <version>1.2</version>
                <scope>provided</scope>
            </dependency>
            <dependency>
                <groupId>javax.el</groupId>
                <artifactId>el-api</artifactId>
                <version>2.2</version>
                <scope>provided</scope>
            </dependency>

            <dependency>
                <groupId>org.glassfish.web</groupId>
                <artifactId>el-impl</artifactId>
                <version>2.2</version>
            </dependency>

It is working state of pom.xml

An more I delete

servlet-api
jsp-api
jstl
el-api

jar files from tomcat/lib

And copy from m2./repository.
