The server sources hosting on sourceforge is currently stopped. All sources are available here.

However a general documentation can be still accessed from Source Forge

Check release notes and a change log in a corresponding release number directory: TJWS2/1.x/notes/

Good news

The project doesn't use Log4J, and other not reliable open source libraries.

tjws2's Issues

Unhandled null pointer exception at initializing a servlet

I post this issue on behalf of Robert Roth
I had a typo in the
attribute name and because I didn't check for null I created a
NullPointerException. The problem was that it happened in the init()
function of a servlet that was supposed to be initiated at startup.
This lead to Atjeews crashing every time I tried to start it. Because
of that and becasue it happened on an unrooted phone I couldn't remove
the offending servlet either. The only option was to re-install
Atjeews.

I think the problem lies here:

TJWS2/1.x/src/rogatkin/web/WebAppServlet.java

Line 379 in be9d1de

} catch (ServletException se) {

try {
instance.init(ServletAccessDescr.this);
} catch (ServletException se) { // this should probably be: }
catch((Exception e) {
exHolder[0] = se;
}

Hello,

Im using CBL with TJWS and have issue when self signed certificate is been used.

couchbase/couchbase-lite-java-listener#78

If i use the proper valid Certificate from trusted CA and apply in TJWS will solve this isssue?

Thanks
Nithin

Installation and Configuration

• prepare log file
  • sudo mkdir -p /var/log/tjws/
  • sudo chown user.user /var/log/tjws/
  • sudo chmod u+wx /var/log/tjws/
• sudo chmod a+rx /opt/tjws/lib/
• sudo chmod +rx /opt/tjws/bin/
• sudo cp /opt/tjws/bin/tjwserv /etc/init/tjwserv.conf
• sudo chmod +x /opt/tjws/bin/tjwserv.sh
• sudo /opt/tjws
• update the port and log mode(debug or info, etc.) at /opt/tjws/bin/tjwserv.sh
• sudo service tjwserv start
• wait a moment, ~1 min, see the log file

• update xyz.war into webapps/ at any time, wait ~30Sec, it will update the new content by itself

broken link in readme.md

The space in the link to source forge breaks the link. "http:// tjws.sf.net" should be "http://tjws.sf.net"

FastClasspathScanner is outdated -- consider porting to ClassGraph

Your project, drogatkin/TJWS2, depends on the outdated library FastClasspathScanner in the following source files:

• 1.x/src/rogatkin/wskt/EndPointScanner.java
• 1.x/src/rogatkin/wskt/SimpleProvider.java

FastClasspathScanner has been significantly reworked since the version your code depends upon:

• a significant number of bugs have been fixed
• some nontrivial API changes have been made to simplify and unify the API
• FastClasspathScanner has been renamed to ClassGraph: https://github.com/classgraph/classgraph

ClassGraph is a significantly more robust library than FastClasspathScanner, and is more future-proof. All future development work will be focused on ClassGraph, and FastClasspathScanner will see no future development.

Please consider porting your code over to the new ClassGraph API, particularly if your project is in production or has downstream dependencies:

• https://github.com/classgraph/classgraph/wiki/Porting-FastClasspathScanner-code-to-ClassGraph
• https://github.com/classgraph/classgraph/wiki/Code-examples
• https://github.com/classgraph/classgraph/wiki/ClassGraph-API

Feel free to close this bug report if this code is no longer in use. (You were sent this bug report because your project depends upon FastClasspathScanner, and has been starred by 50 users. Apologies if this bug report is not helpful.)

Missing some packages

Hi,

some packages are missing ex : rogatkin.app.remote

it uses in /rogatkin/app/SimpleJndi.java

can you publish them please

Philippe

servlet invoked twice when use wildcard /*

public class MainTest {
public static void main(String[] args) {
final Serve srv = new Serve();
java.util.Properties properties = new java.util.Properties();
properties.put("port", 80);
properties.setProperty(com.koogu.server.Serve.ARG_NOHUP, "nohup");

	//properties.setProperty("acceptorImpl", "Acme.Serve.SelectorAcceptor"); // this acceptor is requireed for websocket support.
	srv.arguments = properties;
	srv.addServlet("/*", new HttpServlet() {
		private static final long serialVersionUID = 1L;
		protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
			System.out.println("test="+req.getParameter("test"));
		}
	}, null); // optional
	Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
		public void run() {
			srv.notifyStop();
			srv.destroyAllServlets();
		}
	}));
	srv.serve();
}

}

then doGet was invoked twice:
URL: http://localhost/a?test=123
output as:
test=123
test=null

support for jsp is broken?

Try run jsp page and get this error:

How do i register a filter

I tried server.addFilter(String, Filter) but it doesn't seem to work. I am looking to add a basic filter which checks if session is valid on each request.
