Shell Script Run Java Jar Service

I want to create a shell script to run java service. The actual command is 

java -Dorg.vertx.logger-delegate-factory-class-name=org.vertx.java.core.logging.impl.SLF4JLogDelegateFactory -Dlogback.configurationFile=conf/web/logback.xml -jar vertx-web-0.1-fat.jar -conf conf/web/conf.json -cluster -cp conf/web:conf/web/lib/slf4j-api-1.7.12.jar:conf/web/lib/logback-classic-1.1.2.jar:conf/web/lib/logback-core-1.1.2.jar

it works if I execute it just like that. But it's gonna be inaffective and messy. I decided to create a shell script :

#!/bin/sh

app_name=vertx-web-0.1-fat.jar

#::=== logger
logger_name=logback

#::=== config
config_base=conf/web
config_app=conf.json
config_log=logback.xml

#::=== arguments
args_factory_logger=org.vertx.logger-delegate-factory-class-name=org.vertx.java.core.logging.impl.SLF4JLogDelegateFactory
args_classpath=conf/web:conf/web/lib/slf4j-api-1.7.12.jar:conf/web/lib/logback-classic-1.1.2.jar:conf/web/lib/logback-core-1.1.2.jar

args_other=-cluster

#::=== execute
java -D$args_factory_logger -D$logger_name.configurationFile=$config_base/$config_log -jar $app_name -conf $config_base/$config_app $args_other -cp $args_classpath

But it doesn't work and the response 

: command not found
: command not found
: command not found
: command not found
: command not found
: command not found
Error: Unable to access jarfile vertx-web-0.1-fat.jar
: command not found

Can you give me any clue or solution? Thank you

Regards, Stefio

When you are assigning value to your variable, shell is treating special character as key character(not as value). thus trying to execute the special char ":".

What you need is to use quotes , either strong quote or week quote depending on your need.

In your case i suggest strong quotes.

so you command should be like :

 args_classpath='conf/web:conf/web/lib/slf4j-api-1.7.12.jar:conf/web/lib/logback-classic-1.1.2.jar:conf/web/lib/logback-core-1.1.2.jar'

I think that you need to delcare var in the safe way. For best practices I allways define var like this:

myVar="My.contet"

So after a little refactoring I think that the script could be:

#!/bin/sh

app_name="vertx-web-0.1-fat.jar"

#::=== logger
logger_name="logback"

#::=== config
config_base="conf/web"
config_app="conf.json"
config_log="logback.xml"

#::=== arguments
args_factory_logger="org.vertx.logger-delegate-factory-class-name=org.vertx.java.core.logging.impl.SLF4JLogDelegateFactory"
args_classpath="conf/web:conf/web/lib/slf4j-api-1.7.12.jar:conf/web/lib/logback-classic-1.1.2.jar:conf/web/lib/logback-core-1.1.2.jar"

args_other="-cluster"

#::=== execute
java -D${args_factory_logger} -D$logger_name.configurationFile=$config_base/$config_log -jar $app_name -conf $config_base/$config_app ${args_other} -cp ${args_classpath}

if you want to see the command executed use the echo command:

echo "java -D${args_factory_logger} -D$logger_name.configurationFile=$config_base/$config_log -jar $app_name -conf $config_base/$config_app ${args_other} -cp ${args_classpath}"

To launch the java app as a service I recommend you take a look at JSVC project. This is really easy to implement and that takes care of many things for you.
