I just ran the tutorial locally, and everything is working correctly for me.
I built the example web service using sh example-python.sh rather than building the service using the web UI at http://localhost:55000.

I'm not sure when this started happening, but I noticed it because it broke my ability to use Github.
I started encountering the error key_exchange_identification: banner line too long when trying to use any git commands that interact with the remote when the remote is Github (haven't tested with Enterprise GH or non-GH locations). Investigating further, I found that the underlying ssh commands were failing because the banner line contained an entire HTML document. ssh -v -T git#ssh.github.com output follows:

I have tried:
several different identity files, changed both in the config and on the command line;
accessing ssh.github.com both directly (as above) and via a config file; and
using a new blank config file.
These all produced the same output.
I have also tried using WSL2 Ubuntu 20.04, with its own identity and config files, and that worked perfectly fine, so I don't think it's a proxy or network issue.
debug1: Connecting to ssh.github.com [192.30.255.123] port 443.
According to this you're supposed to be connecting to port 443 on one of github's load balancers. When I connect to that address and port, I get an SSH server version string which is the expected result.
It seems likely that a firewall or similar network device, probably within your local network environment, is interfering with your connections to github. The "/mwg-internal" URL in the HTTP suggests that you're connecting to a McAfee Web Gateway instance.
You could try switching git to use HTTPS URLs for the repo that you're trying to access. If you need to connect through SSH, you should contact your local network administrators for help.
I've using Geoserver 2.20 downloaded from official site, I have configured gwc cache system and enabled layer for cache and global services over OGC Services on global settings.

But this other URL for same sever and layer (with) runs ok: http://mysever/geoserver/gwc/demo/ws:mylayer?gridSet=EPSG:4326&format=image/png.
I've looked for this related question (Geoserver:No such workspace 'gwc/service') but do not solve my problem.
How can I solve it?
Regards.
The problem is the URL. It is incorrect.
Correct URL must refer to wmts service and not wms.
So it should be (for this example):
http://myserver/geoserver/geoserver/gwc/service/wmts?SERVICE=WMS&REQUEST=GetMap&BBOX=-180,-90,0,80.33032694475760138&SRS=EPSG:4326&WIDTH=846&HEIGHT=800&LAYERS=ws:mylayer&FORMAT=image/png
Available layers:
http://myserver/geoserver/geoserver/gwc/service/wmts?
Regards.

Please suggest someone where I need to correct the code.I tried on google also but didn't find?
PS:All the required jars and libraries are imported correctly.
Thanks in advance!!!
Agreed with M. Deinum's comments about memory issues, however to resolve your described issue below approaches should work :
either set your browser's language to hindi or telgu as these are the prop files you added in resources and running the code to get it.
or Add one more property file Data_en.properties because your browser's language would be english during execution of jsp code and there was no prop file related to english message and throwing error "NoSuchMessageException: No message found under code 'lable' for locale 'hi,en-in;q=0.5'" which correct quite obviously ;)
I have been trying to implement the same. My interpretation is something like this: After executing the line
String lang=request.getHeader("accept-language");
The variable lang contains the string - hi,en-in;q=0.5 . Consequently the locale value will also be - hi,en-in;q=0.5. while parsing through spring.xml file, IOC searches the locale hi,en-in;q=0.5 within the registered locale names. Since the locale with given name is unavailabe, It prompts the error message:
org.springframework.context.NoSuchMessageException: No message found under code 'lable' for locale 'hi,en-in;q=0.5'.
Possible solution:
Assign "lang" variable with either "te" or "hi".
Set your browser such that the value of
"request.getHeader("accept-language")" will be "te" or "hi".
This is my first Spring Boot example and on the first step. I created a SpringBoot project in STS 3.8 like this:
File -> New Spring Starter Project
Dependecies -> Web
I created the following controller in src/main/java/com.first.boot
IndexController
package com.first.boot;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class IndexController {
#RequestMapping("/")
public String index(){
return "index";
}
}
Next, I created view index.html in src/main/resources/templates:
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Getting Started: Serving Web Content</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
Welcome to your first Spring Boot Page
</body>
</html>
Then I run the project as:
Right click on project -> Run as -> Spring Boot App
The console shows proper mappings and Tomcat startup information
Mapped "{[/]}" onto public java.lang.String com.first.boot.IndexController.index()
Tomcat started on port(s): 8080 (http)
Started FirstSpringBootApplication in 4.096 seconds (JVM running for 4.843)
Initializing Spring FrameworkServlet 'dispatcherServlet'
FrameworkServlet 'dispatcherServlet': initialization started
FrameworkServlet 'dispatcherServlet': initialization completed in 64 ms
But whenever I run localhost:8080 on browser, I see this page:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Tue Dec 13 08:22:13 IST 2016
There was an unexpected error (type=Not Found, status=404).
No message available
There are no errors in console.
Adding following dependency solved the issue:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>

I have a Hadoop cluster with Kerberos enabled I want to put files on HDFS using a windows/linux machine outside the cluster.
Hadoop admin team have provided me with username to access hadoop and keytab file, how should I use them in my java code?
I went through many resources on internet but none of them give any guide for accessing kerberized hadoop from outside the cluster.
Also, Is it necessary to run the code using hadoop jar? if yes how will I run it fromo outside the cluster

But curl is not working(windows)

Please suggest
This can be achieve through hdfs command. All you need is hadoop distribution and configuration files which present on namenode.
Copy the hadoop distribution on the client node. It means you have to copy the complete hadoop package to the client machine.
Refer this
Get a user ticket from keytab using kinit command which is a command line tool for java.
a. Install jdk in you client machine.
b. Set JAVA_HOME, see here
c. Create a krb5.ini file in the location C:\windows\krb5.ini. This file should contain below information,
[libdefaults]
default_realm = REALM
[realms]
REALM = {
kdc = kdcvalue
admin_server = kdcvalue
default_domain = kdcvalue
}
[domain_realm]
.kdcvalue = REALM
kdcvalue = REALM
REALM - Server Realm name
kdcvalue - Server host name or ip address
d. Make sure java bin path set in the PATH variable in windows machine. Open command prompt, Type the below command to get user ticket.
kinit -k -t keytabfile username
Now you can able to put the file into HDFS using "hadoop fs -put src dest" or using java.
