Hillshade.java error messages

FerasObeidat — Mon, 22 Sep 2014 20:19:04 GMT

hi all,

while start running HillshadeCommand in eclipse I got these error messages, even-though there was no error in the code :

Starting HillshadeCommand - An ArcObjects SDK Developer Sample

java.lang.UnsatisfiedLinkError: no ntvinv in java.library.path

Could not load native libraries.

Hi Feras,

Please look at the KB article

29348 - java.lang.UnsatisfiedLinkError: no ntvinv in java.library.path

java.lang.UnsatisfiedLinkError: no ntvinv in java.library.path

The PATH variable does not include a directory which contains the native libraries required for ArcObjects Java classes to function.

Solution or Workaround

Add the directory that contains the native libraries needed by ArcObjects Java to the PATH variable.

On both Windows and Unix platforms, add either of the following directories to the PATH variable:

A. $ARCENGINEHOME\java\jre\bin
B. $ARCENGINEHOME\bin $ARCENGINEHOME may need to be replaced with the location of the ArcGIS SDK installation."

Thanks,

Shriram

Hi Shriram,

I updated the Path to include "C:\Program Files (x86)\ArcGIS\Desktop10.2\java\jre\bin"

But still the problem is not resolved, would you please elaborate more on it, I am new in this domain

Cheers,

Feras

Feras,

Sure. Hope this information is helpful.

First, please make sure you meet the system requirements System Requirements

ArcGIS for Desktop, ArcGIS Engine, or ArcGIS for Server is required to develop with ArcObjects SDK.

Java Development Kit (JDK) version 6. Update 20 and above are supported.

Second, make sure you are pointing to 32bit jre when using eclipse.

Hi Shriam,

This is what I have on my system related to ArcGIS:

- C:\Program Files (x86)\ArcGIS\Desktop10.2

- C:\Program Files (x86)\ArcGIS SDKs

Eclipse is working fine, as I tested it with other ArcGIS application (DrawingOverlayApp) and it works fine

Hi Feras,

Not sure of the exact problem. But at higher level, here is the direction I would go to troubleshoot the issue.

If the problem is not with the code, not the with java environment then I would say check the licenses. Seems like this sample requires 3d analyst extension - do you have those licenses available? Also if at all you are working data that is something you need to look at.

Thanks,

Shriram

I took the code from this site, I copied it into my Eclipse and just ran it. First there were problem highlighted in red and then I added the external libraries arcobjects.jar to get that resolved. Then, I simply run it and got the error. Yes I have the licence, how this can be used within the code? do you have other example that's working with a sample file.

Very much appreciated Shriram!

Hello Shriram,

I would be grateful if you can send me all steps that are required to run HillshadeCommand.java from eclipse .

However, I was successfully able to run the following class in java through eclipse: DrawingOverlayApp.java

But still having problem to run HillshadeCommand, I think it will good to start all steps from beginning so I avoid missing any thing? any help ?!

Thanks,

Feras

Hi Feras,

I typically work more with .NET Arcobjects rather than on Java Arcobjects. Having said that, I'll see what I can do about it.

Btw - do you have ESRI technical support account?

Regards,

Shriram B

Hi Feras,

With help of one of my collegue, Kwasi A, I was able to run the sample successfully.. makes sure you have "C:\Program Files (x86)\ArcGIS\DeveloperKit10.2\java\samples\data\raster" folder on your system.

I'll send the zipped project as well.

Hello Shriran,

Thanks!

however, I don't have DeveloperKit10.2 under ArcGIS

I searched for it and I didn't find this folder, under ArcGIS I have: C:\Program Files (x86)\ArcGIS\Desktop10.2 which contains other folders like ArcGlobeData, arcpy, ...Attached is a snapshot of what I have under this

Re: Hillshade.java error messages

ShriramBhutada1 — Wed, 24 Sep 2014 15:51:56 GMT

Did you install ArcObjects Java SDK? Once you install that then you can see the folder

.btw Special thanks to Kwasi Asante‌, he helped me run the sample.

~Shriram

Re: Hillshade.java error messages

ShriramBhutada1 — Wed, 24 Sep 2014 16:08:20 GMT

DeveloperKit10.2 folder should be under C:\Program Files (x86)\ArcGIS.

~Shriram

Re: Hillshade.java error messages

FerasObeidat — Wed, 24 Sep 2014 16:15:49 GMT

Then I would be grateful if you guide me on how to install the developer kit. I saw some sites but was not clear for me

my phone is 519 661-2111 ext 82253

Many thanks!
