Are you looking for a way to run Java apps easily? Well, then look no further as this is the perfect update for Java Runtime Environment. Why is Java Runtime Environment necessary? Java Runtime Environment is necessary as it has all of the necessary libraries and other important parts which are required to run any applications or web programs that are made in the Java programming script. Java Runtime Environment, like the name suggests provides an environment for the virtual machines to run by processing all of the codes.
In that case, try to use other versions of the libraries, that do not rely on the com. After struggling for a while I finally got this to work with eclipse. After finally reading the documentation I realized that the -vm argument must be on a separate line, unquoted, and ahead of any -vmargs:. I got similar error. This is because JDK is not properly set in eclipse. I tried copying the tools. Then all the compiler errors went away. Reinstalling the JDK didn't fix it.
The other alternative I've seen is adding the dependency with the right path in each pom xml file, but the playn-samples has lots of files that is a ridiculous pain to have to edit. Add this dependecy in pom. Hope this help. As other posters have stated the issue here has to do with the JRE that eclipse is using not being able to find the tools jar.
I solved the issue by going in a bit of a different direction than what was stated above, and it was because of the way that my projects and environment. Eclipse 4.

As the security level is increased, more restrictions are placed on allowing an application to run, and stronger warnings are issued to the user. Very High - Applications that are signed with a valid certificate that is located in the Signer CA keystore, and include the Permissions attribute in the manifest for the main JAR file are allowed to run with security prompts.
All other applications are blocked. High - Applications that are signed with a valid or expired certificate that is located in the Signer CA keystore, and include the Permissions attribute in the manifest for the main JAR file are allowed to run with security prompts. Applications are also allowed to run with security prompts when the revocation status of the certificate cannot be checked. See Rich Internet Application Deployment Process for information on how the decision to run or block an application is made.
The Security Level setting affects plug-in applets, Java Web Start applications, embedded JavaFX applications, and access to the native deployment toolkit plug-ins. This setting does not affect stand alone Java applications.
RIAs from the sites listed are allowed to run with applicable security prompts. Click Edit Site List to add, edit, and remove items. If an active deployment rule set is installed on the system, the link View the active Deployment Rule Set is shown before the Manage Certificates button.

The user can import, export, remove, and view the details of a certificate. For instance, on Microsoft Windows 7, the default location of the keystore files for user jsmith would be as follows:. For non-default locations of the certificate keystore files, specify them in the User-Level deployment.
For System-Level certificates, the only options a user has are Export and Details. Trusted, Secure Site, and Client Authentication certificate keystore files do not exist by default. Thus there are no default locations for them. The location of the keystore files for the various types of certificates can also be set in a System-Level deployment. The System-Level deployment. It is specified in a deployment. See System-Level deployment. The following properties may be specified:.

A Java application or applet that is launched with Java Web Start can either be installed or cached on the client computer.
If the Java application is cached, then Java Web Start stores the entire application in its cache; the application is removed from the client computer when Java Web Start empties its cache.
If the Java application is installed, then the application will have an entry in the Add or Remove Programs applet in Windows Control Panel. A Java application or applet can specify if it prefers to be cached or installed; if the Java application specifies that it prefers to be installed, then it is hinted.
