Using Worklight 6.2
I deployed the application into Worklight Server
I open the Worklight Console and click on 'Preview'
I could not see the Mobile Browser Simulator; the browser only displays the index.html page of the application without the Mobile Browser Simulator.
There is stacktrace in the Worklight Console.
I am pasting a portion of the stacktrace below.
-

It is very possible that you have another instance of JVM running that are doing the same thing, perhaps you can kill the java process and try again.

I have removed cn1 plugin from NB, downloaded new copy of the native maps cn1lib, cleaned and built and i still get the same error... please help.

This started happening to one other user I'm aware of (but not to everyone surprisingly) as a result of the change to remove the maps in location manager. We had to remove them as Google became far too strict with maps key generation strategies.
We have a fix for this and will post it later on today or tomorrow morning.
I have an error within my project. I'm not sure what happened but I was working on my app and all of a sudden the Theme.res file stopped working. When I try to access the Theme.res file, I receive an error saying
Fatal Error loading the resource file: java.io.EFOException
When I run the project the console output displays this:

I don't know what happened because everything was running fine and then all of a sudden this error randomly occurred. What can I do to fix this problem? Can I restore/recover my Theme.res file?
Note: I am using Netbeans on Windows 7.
I notice that after changing from solr 5.3 to 6.1, my code that creates an EmbeddedSolrServer (see below) will cause the following exception:
String solrHome = prop.getProperty(PROPERTY_FIELD_SOLR_HOME);
String solrCore = "anotherCore";
CoreContainer solrCores = new EmbeddedSolrServer(
Paths.get(solrHome), solrCore
).getCoreContainer();
EmbeddedSolrServer mycore=
new EmbeddedSolrServer(solrCores.getCore("mycore"));
The last line works ok with solr 5.3, but with 6.1, the following exception is generated. Any ideas please?

I'm having the same issue, but I imagine its because they removed that class from 6.1 (or sometime after 5.3). Removing the element from solrconfig.xml in the problematic core worked for me and should hopefully do the trick for you as well.
<!-- find this line in your solrconfig.xml and comment/remove it -->
<requestHandler name="/admin/"
class="solr.admin.AdminHandlers"/>
Help please !

What is the classpath set when you run your code from the command line?
The error means you're missing the jar containing the declaration for OWLOntologyCreationException - this is either the owlapi-api jar or the owlapi-distribution jar, depending on how you set up your Eclipse project.
i was attempting google app tutorial 1 from this link.https://googcloudlabs.appspot.com/codelabexercise1.html
Followed exactly what they did and there is an error code of folders missing in WEB-INF/lib directory. So i imported Google API, Google Datastore Beta 2. Then i encountered this error.
Oops! Google Chrome could not connect to localhost:8888
The log in my console is as follow.
