There is an old applet, a manifest is created using maven. But what exactly should be in the manifesto? That's what I added there, but it didn't help:

Permissions: all-permissions Codebase: * Caller-Allowable-Codebase: * Application-Library-Allowable-Codebase: *

What is there still not enough? Worth java 1.7.0_67.
Here is a mistake:

 ava.lang.SecurityException: JAR manifest requested to run in all-permissons only: file:/C:/TestToApplet/Applet.jar at com.sun.deploy.security.DeployManifestChecker.verify(Unknown Source) at com.sun.deploy.security.DeployManifestChecker.verify(Unknown Source) at com.sun.deploy.security.SandboxSecurity.isPermissionGranted(Unknown Source) at com.sun.javaws.security.JNLPSignedResourcesHelper.checkSignedResourcesHelper(Unknown Source) at com.sun.javaws.security.JNLPSignedResourcesHelper.checkSignedResources(Unknown Source) at sun.plugin2.applet.JNLP2Manager.prepareLaunchFile(Unknown Source) at sun.plugin2.applet.JNLP2Manager.loadJarFiles(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

HTML code is fully described in the question. Security settings block signed applet launched via Javascript

Maybe the problem is not in the manifest, but in jnlp? He is also described in the question on the link above.
