Sounds like the issue is the java version you are using. Which one is it? — afelisatti
emm i have jre1.8.0_40 i should mention that the server where I am trying to deploy is on another machine, I don't know what version of java is installed there. that must be it the problem?! — Rajeun
Mule 3.5.0 does not support Java 8, there could be issues there for sure. I suggest trying with Java 7 or even 6 (since that is the version used when testing). — afelisatti
I am lost :(. in my machine I have java 8 I deployed the application on my local server and it worked well. I thought I have to install the same version of java on the other machine or is my mule server. iF MULE 3.5.0 don't support java 8 why my application worked well in my machine. — Rajeun
It's not supported but it could work (depending on what modules you use for example), it just wasn't tested properly. And as was mentioned below, it also depends on the Java version you are using in Studio. — afelisatti

Check the version which you are compiling the source code in the IDE... looks like you are using java 8.

After that, check which version is using your mule-standalone-server.
