Hi, I'm getting the following Exception when trying to run a java webapp on an ec2 instance.. I have the following dependency added to pom.xml.

dependency>

<groupId>redis.clients</groupId>

<artifactId>jedis</artifactId>

</dependency>

I have redis-server 3.0.5 installed as mentioned here: http://redis.io/download

I'm initializing the pool object by making this call:

private static JedisPool pool = new JedisPool(new GenericObjectPoolConfig(), "localhost", 6379,0,null,5); and then use pool.getResource() and pool.returnResource()..

I also tried these:

private static JedisPool pool = new JedisPool(new JsonPoolConfig(), "localhost", 6379,0,null,5);

private final JedisPool pool = new JedisPool("redis://localhost:6379");

Still no luck.

Everything is working fine in my local, but not in the remote server.

Is it happening because I have two conflicting jedis and redis versions?

Arvind,

Jedis uses apache commons-pool2 in the background. I'd recommend to check that the proper commons-pool2 jar is being included in the webapp.

I too have faced same problem some time back,Jedis uses apache commons-pool2 in the background but jedis jar doesn't includes apache commons-pool2 in it so you have to add it externally.

Hi,

Solved this issue!! Here is the solution in case anyone else faces this issue:

I was using webapp-runner jar to deploy this webapp. I changed it's version to the latest one. (7.0.35 to 8.0.24.1 at the time of this post, scope set to provided - because it's given in the command line when deploying)

Also, excluded the commons-pool2 used in redis 2.4.2 dependency, changed redis version to latest one, and added the latest commons-pool2 as a separate maven dependency.

Changes here:

OLD:

         <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.4.2</version>
         </dependency>

NEW:

         <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>

            <version>2.7.3</version>
            <exclusions>
                <exclusion>
                    <groupId>org.apache.commons</groupId>
                    <artifactId>commons-pool2</artifactId>
                </exclusion>
            </exclusions>
         </dependency>
         <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>
            <version>2.4.2</version>
         </dependency>
