I cant see whats wrong but when i debug it points me to this line in another class screen.render(pixels, 0, WIDTH); (Line 126)

I have made report in Jaspersoft studio and it runs without any problem.
Trying to run it from latest jasperstarter:
JasperStarter 3.5.0-java7 Rev 76746ab (JasperStarter-3.5.0-java7)
- JasperReports: 6.4.0
It produces error:

Can anyone please give a hint what to do to remedy this situation.
Are there some jar files I should copy from Studio to jasperstarter to make it work?
I'm a new user in RePast learning to run the mesoFON model. I get this error message. What is the problem?

It appears that there is an issue with a mesoFOM specific-method call. I'd suggest reaching out to the mesoFOM model developers directly to see if they can help.
I am trying to run the Protege Reasoner, there are two reasoner available Fact++ and HermiT 1.3.7.
I tried to run the both but their is window comes and suddenly goes. It's difficult to see that one so I use the screen recorder to get that but it doesn't contain any information.
There is no error message or log message I can found.
The reasoner is not being started.
I tried to use the option Export inferred axioms as ontology and then I get the expected error message "No Reasoner intialized"
Please suggest.

The stack trace confirms that FaCT++ does not allow custom datatypes to be specified - this is currently a known limitation. I don't know about HermiT but there's a good chance the problem is the same.
Pellet used to have more flexible datatype treatment, you can try installing it and use it instead of HermiT or FaCT++
I'm getting below exception in the reduce task of a Pig Script. I have googled it around, but I'm unable to find a reason for this. Could anyone please throw some light on it ?

Without these registrations that I added Storm can run normally, so I'm sure the exceptions are thrown because of the registrations I added in conf/storm.yaml, not any other configuration in conf/storm.yaml. I guess there may be some format errors and Storm could not parse conf/storm.yaml correctly. But I have examined the lines I added, for example, 1) there is no tab before "- custom.Car: custom.MyCarSerializer" and instead they are blank spaces; 2) there is a blank space following "- custom.Car:". But this can not solve the problem. Who has a similar problem and how did you solve it?
My storm's version is 0.9.0.1, and I run it in remote mode.
Definitely, your storm.yaml isn't a valid YAML file. As #user2720864 said, post your storm.yaml file.
Meanwhile, validate your YAML file using YAML Lint service.
