I'm getting " TLS 1.0 has been disabled in this organization. Please use TLS 1.1 or higher when connecting to Salesforce using https." error when I refresh my eclipse. I performed below actions to fix the issue, but I'm not able to fix the error. 

1) Checked the critical updates - There is no update related to TLS 1.0 in my sandbox
2) I have Java 1.7 Version and enabled TLS 1.1 and 1.2. 
3) Enabled TLS 1.1 , 1.2 in all the browsers.
4) Added "-Dhttps.protocols=TLSv1.1,TLSv1.2"

Please let me know, is anything am missing here to fix this issue? 

After running 

 

java -classpath wsc-22.jar com.sforce.ws.tools.wsdlc enterprise.wsdl enterprise.jar

 

I get the error:

 

Error could not find or load main class com.sforce.ws.tools.wsdl

 

I downloaded wsc-22.jar and put it in my classpath what am I missing?
