Here is the solution for your problem:

To turn on this boolean you simple have to use this line (root permissions)

setsebool -P httpd_can_network_connect on

or

sudo setsebool -P httpd_can_network_connect on

Hope that helps. Reference see here: https://wiki.centos.org/TipsAndTricks/SelinuxBooleans

apache 2.4.6 virtual host reverse proxy Your browser sent a request that this server could not understand

The case i hit this is due to apache configuration version issue.

Source URL: https://stackoverflow.com/questions/10445455/apache-dont-have-permission-to-access-on-this-server-when-i-am-using-virtua

This configuration was valid for apache version 2.2

First check your apache version by typing apachectl -V in your terminal.

If it shows something like this

Server version: Apache/2.4.27 (Ubuntu)
Server built:   2018-04-18T14:20:05

then your apache version has updated but the conf you are using is deprecated.

So instead of

2.2 configuration:

Order allow,deny
Allow from all

use this:

2.4 configuration:

Require all granted

For further documentation related to the upgrade, follow the official docs:

java regex between multiple lines

Searched by: java regex between multiple lines

Source URL:
https://stackoverflow.com/questions/3651725/match-multiline-text-using-regular-expression

First, you're using the modifiers under an incorrect assumption.

Pattern.MULTILINE or (?m) tells Java to accept the anchors ^ and $ to match at the start and end of each line (otherwise they only match at the start/end of the entire string).

Pattern.DOTALL or (?s) tells Java to allow the dot to match newline characters, too.

Second, in your case, the regex fails because you're using the matches() method which expects the regex to match the entire string - which of course doesn't work since there are some characters left after (\\W)*(\\S)* have matched.

So if you're simply looking for a string that starts with User Comments:, use the regex

^\s*User Comments:\s*(.*)

with the Pattern.DOTALL option:

Pattern regex = Pattern.compile("^\\s*User Comments:\\s+(.*)", Pattern.DOTALL);
Matcher regexMatcher = regex.matcher(subjectString);
if (regexMatcher.find()) {
    ResultString = regexMatcher.group(1);
} 

ResultString will then contain the text after User Comments:

Project Facets doesn't have 1.8 as option for java.

I solved the problem. Go to Project Properties -> Project Facets -> Runtime -> New -> Add a tomcat server and in JRE select JRE1.8.0_XX.

Why most posts telling slf4j is better than apache commons log to work with log4j.

Edited: 2019-Aug-08_pm063733

Recently due to some event, lead me to double check again about:

1. slf4j
2. log4j
3. apache commons logging

Which facts so far I found were showing different story...






https://commons.apache.org/proper/commons-logging/

1.0.4 Release - 16 Jun 2004

The 1.0.4 release of commons-logging is a service release containing support for both the 1.2.x and 1.3.x series of Log4J releases.

https://www.slf4j.org/news.html

13 April 2005 - start of work on SLF4J project

Launch of the SLF4J project. Work has begun on the web-site, svn repositories as well as the source code.
