Something to do with eclipse as I can run the code successfully in cmd.
I am using standard oracle Java version 15 and eclipse version 2020-12(4.18.0) on windows 10
HttpURLConnection httpUrlConnection = (HttpURLConnection)url.openConnection();
At the line above I am getting error as pasted below.
Please note: System.out.println(System.getProperty("java.security.properties")); gives null

According to Rita Homepage you just have to download Rita.jar and
WordNet-3.1 and add both to thebuild path of your java project.
I did it like that and everytime i try to use it:
RiWordNet wordNet = new RiWordNet(Test.class.getResource("/WordNet-3.1").getPath());
I get:

The data files are no longer supplied as part of the installation. You need to download the WordNet version for your platform and then pass it to the constructor, as documented here.
Periodically we have this problem that prevents an applet to go running, the process javaw.exe seems locked, killing them several times unlock the applet. In the trace file I find this (we have jdk 1.6_35, the applet is used by a j2ee web application):

For some reason this problem is originated from an hidden update of java, installing jdk 7u45 and then removing solve for some time the problem.....
I'm going crazy....
This is happening because there are more security checks that have been imposed on applets in the new release of the JRE (7u45-b18).
http://www.oracle.com/technetwork/java/javase/7u45-relnotes-2016950.html#newft
Its good to be on old JRE or implement security related changes.
My application was running fine until I upgraded my jre to 7u40. When my application is initializing, it's doing Logger.getLogger("ClassName"), and I'm getting the following exception.

The exception is coming from this line:
private static Logger logger = Logger.getLogger(Applet.class.getName());
Could it be because of any sideeffects with fix http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8017174 ?
A workaround is to open the java control center and enable logging. This is a concern since by default "Enable Logging" is unchecked. If I select "Enable Logging", the application starts fine.
This problem seems to be fixed in java7 update 45.
Try to package java.util.logging.* with your app in a JAR, and make sure it's on the classpath. That way it is always available. Also, what does your logging.properties look like?
I have written an applet program. It has some references to classes from java tools.jar in it (eg:- import com.sun.jdi.connect.IllegalConnectorArgumentsException)
When I run this applet through appletviewer utility it works fine. But when I embed this applet in HTML file and try to run it through web browser, I am getting exception about some classes not found at runtime:-

Exception: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/sun/jdi/connect/IllegalConnectorArgumentsException
However the IllegalConnectorArgumentsException class is part of java runtime located inside tools.jar.
How I can get run it inside browser as well?
many thanks in advance.
Regards,
Pras
You are running your applet from the JRE. The class IllegalConnectorArgumentsException can only be access from the JDK since it's related to debugging.
Refer to this question.
