Error Deploying JAVA
 

We are having an issue when we try to deploy our code. We get two lines of errors:
[crio] task 0x2869fd8 (mdns resolve) deleted: errno=0 (0) status=0 (0)
[crio] task 0x2bff138 (mdns resolve) deleted: errno=0 (0) status=0 (0)
Then the process just stops and we get solid act/link lights on both the crio and the bridge and the PC

What are we doing wrong?

Re: Error Deploying JAVA
 

Hey guys,
We are desperate. Three night and our rookie team is dying here. We need some help from the experts.

Re: Error Deploying JAVA
 

Were there any other messages in the console window?

Can you verify that you can ping the cRIO? You should open a CMD window on your PC that is connected to the robot and type "ping 10.x.y.2" where x.y are your team number. If you don't get a response, there is a connectivity problem.

You might also try to disable the windows firewall on your system to see if that helps.

Let us know what happens after you try those things.

Re: Error Deploying JAVA
 

are you sure that all the dip switches are off?

Re: Error Deploying JAVA
 

Yes we can ping the crio and the pc itself. The dipswitches are all electronic and are set off in the flashing utility. We even reflashed with the image a second time in case it was corrupted. I printed a copy of some other people's error messages and it appears we are not even starting to load the code. My programming teams thinks they may have forgotten to install or update a couple things. We are also istalling all the software on the Classmate to assure it is not a laptop issue.

We did a quick build on Saturday and it actually created more issues than if we followed the step by step instuctions. If you have any other suggestion, let me know and I'll post back tonight with any updates and post the entire output file.

Thanks, Guys

Re: Error Deploying JAVA
 

Hi Steve,

Our rookie team is treading same waters. We may have a corrupted Crio and of course we cannot deploy our java code. If your team was able to get it worked, can you let us know how to's?

Note: Yesterday some of our team members fried two of the jaguars ...

It is still going though

cheers,
George

Re: Error Deploying JAVA
 

Are you able to see the robot via the driver station software?

Re: Error Deploying JAVA
 

OK guys, here's the whole log file for the build and run. This the default sample code from the getting started with java.

Re: Error Deploying JAVA
 

After attempting to deploy, you should be able to open the driver station software and see if it shows you having any code on your robot.

Try hitting the "play" (green triangle) button rather than the debug button. It looks like its a debugger issue and not a deployment issue. I think you can also use F6.

Brad

Re: Error Deploying JAVA
 

Did you try connecting the Debugger? See the instructions starting on the bottom of page 9 of Getting Started with Java (or run the program without debugging the way Brad posted above)

Re: Error Deploying JAVA
 

We get the same error whether we run in debug mode or not. Happens on both development laptops as well as the classmate. After we perform this procedure we get the connected light and robot code light in driver's station but the jaguars do not go solid green and nothing happens.

Actually, the status code of 0 at the end of your previous log is not an error. Are you sure that your program isn't deploying? Is it possible that the program just has an error in it and isn't doing what you're expecting?

Can you try one of the default programs like the simple robot template, and put in some print statements and see if anything comes out on the console? Also, you might want to take out some of the motor code to make it easier.

Brad

Re: Error Deploying JAVA
 

What you're seeing is not an error.

Have you tried Enabling the robot with the Driver Station? Did you rework your DB-37 cable? What is the light next to the 2 pin header on the Digital Sidecar doing? Are all 3 lights on the Digital Sidecar brightly lit?

Re: Error Deploying JAVA
 

Sounds like a good idea to me.

Re: Error Deploying JAVA
 

This is the sample code suggested to use in the getting started package. I'll check the lights in the AM. When we enable it nothing happens. We did not do anything with the DB37, should we have?

Re: Error Deploying JAVA
 

Re: Error Deploying JAVA
 

Ok, we managed to get the problem fixed. The Crio is now working and the robot can now move in tank drive. The fix for the DB37 cable was all that we needed.
Thank you all for the help. :7

Glad to hear you were able to fix it.

Re: Error Deploying JAVA
 

We had had the same error as mentioned in this thread, We took the advice and checked our cable and there was an issue, but that didn't solve that. We are running off of Java on Linux. We also reimaged our cRio to be compiled with LabView and the code compiled onto the robot. The java compiler freezing hasn't changed whether the cable was attached or not.

Re: Error Deploying JAVA
 

Sorry, there's not enough information to go on. Can you provide a full log of what you're seeing? In fact I'd suggest starting a new thread since your problem seems to be different than the OP.

Good luck!

Re: Error Deploying JAVA
 

We are having the exact same problem as the OP, hopefully fixing the cable should resolve the issue.

Just to be clear, when I hit the green button in netbeans it should run all the way through without this error after we fix the cable right?

Re: Error Deploying JAVA
 

When you hit the green button it builds your program, downloads it to the cRIO (using built-in FTP), then reboots the cRIO so your program comes up running.

Fixing the cable will address problems after the program starts. It won't make download properly if it wasn't doing that before.
