Error in executing a Jar file in remote machine

I am trying to executing a jar file which is present in remote machine. When I execute below command from my local machine I get error:

ssh -i /root/.ssh/pem_file user@[host_ip]:/home/user/folder1/java -cp jar1.jar -a option1 -e user1@gmail.com -f TextFile.txt

/home/user/folder1/ is the location where jar file is present on remote machine.The error I get is:

Unknown cipher type 'p'

I then looked up for this error and found out the with ssh we may not need it. So, I removed -cp from it and executed this command:

ssh -i /root/.ssh/pem_file user@[host_ip]:/home/user/folder1/java jar1.jar -a option1 -e user1@gmail.com -f TextFile.txt

Now I get error as:

ssh: Could not resolve hostname [host name]:/home/user/folder1/java: nodename nor servname provided, or not known

How can I resolve this error?

Is that a executable jar? 

ssh -i /root/.ssh/pem_file user@[host_ip] 'java -jar jar1.jar -a option1 -e user1@gmail.com -f TextFile.txt'

Otherwise, follow -cp with the main class:

ssh -i /root/.ssh/pem_file user@[host_ip] 'java -cp jar1.jar full.package.name.ClassName -a option1 -e user1@gmail.com -f TextFile.txt'

The command should be passed to ssh after hostname separated by space not colon, like this:

ssh -i /root/.ssh/pem_file user@[host_ip] /home/user/folder1/java -cp jar1.jar -a option1 -e user1@gmail.com -f TextFile.txt

If you have parts in the command that could be parsed by your local shell before sent to remote host (for example cd /tmp && ls or cat /file | uniq > some.log) it should be enclosed in single quotes:

ssh -i /root/.ssh/pem_file user@[host_ip] 'cd /home/user/folder1 && java -jar jar1.jar -a option1 -e user1@gmail.com -f TextFile.txt'
