Not able to debug webservice using eclipse

i have tried the webservice example mentioned in the below link.
https://codezone4.wordpress.com/2012/11/08/restful-web-services-java-mysql-and-json/.
i build the application with maven deployed in tomcat then clicked on the webservice link in the chrome , not able to access my code.
Now i tried to debug with postman .
I clicked on my webservice class -> then debug -> debug configiuration
then i selected remote application
there values of host and port are
Host : localhost
Port : 8080
then it is showing establishing connection for long time and after that it is showing Failed to connect to remote vm .connection timedout
Can you please guide me how to make deugger working in eclipse to debug the rest api call.

I can find quick solution (In Windows Environment with local host):
1) Download tomcat in your favorite drive (E.g. d: drive)
2) Open startup.bat file under tomcat/bin folder in notepad
3) Replace following line (Which appear at the end of file)
call "%EXECUTABLE%" start %CMD_LINE_ARGS%
with
call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS%
4) Restart your tomcat as it will start with listening port 8000
5) Open Eclipse->"Run"->"Debug configuration"-> Create "Remote Java Application" and provide following information:
Name: sample-name
Project: your project folder
6) Click on Debug button
Note: Make sure Connection properties will have
Host: localhost
Port: 8000
7) Put debug point in your code
8) Open Postman and Hit sample REST API call as you will see the debug point will appear in your code
That's It!

Quoting from your query,
clicked on my webservice class -> then debug -> debug
The project you created requires the restApplication to be deployed on a running server.
Prior To Testing -> check http://localhost:8080 is up or not, and then publish the war into the server.
choose Debug As-> Debug on Server

Debug tomEE on IntelliJ

I know that this answer was asked before, but I couldn't find a clear solution from the given answers.
I want to debug a maven project that implements a web service on tomEE using IntelliJ or any other IDE.
I know that instead of calling the goal tomee:run I must call tomee:debug. And that's what I did:
In IntelliJ, I click on Run / Edit Configurations then +, I chosen Maven, I located the project directory and I set tomee:debugas command line. I started the debug and it says:
Started server process on port: 8080
Listening for transport dt_socket at address: 5005
I think this first step is correct. The second step as I understood is to create a remote configuration, and this is what I failed to do.
What I did is the following:
Run / Edit Configurationsthen +, then TomEE Server. Here I choose local or remote? In my case I think local because the project is local on the device and I call it using localhost:8080.
After that, how to configure this page? What will be the port number 5005 or 8080? And when I finish configuring this page what I do? Run or debug?
I would appreciate a detailed answer because I was not able to understand the short answers given on other questions.

Here's the solution:
Step 1:
In IntelliJ, I click on Run / Edit Configurations then + to add a new configuration, I chosen Maven, I located the project directory and I set tomee:debugas command line. I started the debug and it says:
Started server process on port: 8080
Listening for transport dt_socket at address: 5005
An alternative solution can be by locating the project directory in terminal and running the command: mvn tomee:debug
Step 2: In IntelliJ, I click on Run / Edit Configurations then + to add a new configuration, I chosen Remote, and I specify localhost with port 5005.
Now I click OK, and I debug this configuration.
Breakpoints are detectable and debugging works perfect.

How to debug web project in MyEclipse using JBoss server?

I am new to jboss and myeclipse.
I want to debug my web app using jboss 4.0.4
I am using MyEclipse.
I gone through various links and found we need to uncomment following line in run.bat file
set JAVA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y %JAVA_OPTS%
then after starting run.bat console shows
Listening for transport dt_socket at address: 8787
Then next how do I tell MyEclipse to attach to port 8787 and run my application in debug mode.

You need to define a Remote Java Application in the Eclipse debug configurations:
Open the debug configurations (select project, then open from menu run/debug configurations)
Select Remote Java Application in the left tree and press "New" button
On the right panel select your web app project and enter 8787 in the port field.
Here is a link to a detailed description of this process.
When you start the remote debug configuration Eclipse will attach to the JBoss process. If successful the debug view will show the JBoss threads. There is also a disconnect icon in the toolbar/menu to stop remote debugging.

Define a new server/runtime in MyEclipse, for your JBoss 4 installation. Deploy your project to the defined server and start it in debugging mode.
For more information, go to the MyEclipse learning center, also here.
For earlier releases, check in the inbuilt help.

Debugging client side application

I am trying to debug my client side code which i have checked-out from SVN to eclipse workspace. My server process is already up and running. I have a start-up script for our client which has the following line to start the client.
jre/bin/java splash:images/initializing.png -classpath "$CLASS_PATH" in.co.xxx.xxx.yyy.yyy.launcher.Launcher $* &
I added the debugging related arguments to it
jre/bin/java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=9045,suspend=n -splash:images/initializing.png -classpath "$CLASS_PATH" in.co.xxx.xxx.yyy.yyy.launcher.Launcher $* &
In Eclipse i went to debug configurations entered the hostname and port number(same i mentioned in the startup script (9045)). I added all the client related classes in source tab of debug configurations. Now comes the problem.
When i click debug button after all this, the remote debugger should be launching and waiting for the connection when i fire my start-up script. But it is saying
Failed to connect to remote VM. Connection refused.
Connection refused
I have tried with different port numbers as well. Nothing seems to work. Please suggest what am i missing here .

Did you check Eclipse logs to see if anything further got logged there? Also, when you say debug did not launch 'post authentication page', did you see on the 'server side' if there is a message to 'standard output' stating that the debug port is 'released'? (something similar to this would be emitted on standard output). If this did not show up, then the 'first successful connection' might not have actually released the debugger while you think it did.
Also this works for me here, the only difference I see is that the order of parameters in your and my debug switch are different. Hope this helps!
-Xdebug -Xrunjdwp:transport=dt_socket,address=8080,server=y,suspend=n

Glassfish Server Webservice behind Apache HTTP Server

Hi
We started to create our applications with J2EE. We now created a Webservice and deployed it to the Glassfish Server. We have written an apache proxy rule to access it via https://our.server.com/webservice-war (only https port is open to that server):
ProxyRequests Off
ProxyPass /webservice-war http://our.server.com:8080/webservice-war
ProxyPassReverse /webservice-war http://our.server.com:8080/webservice-war
Now everything works fine, but when we go to the to the ServiceEndpoint page (which is automatically generated) there is a link to the WSDL page:
http://our.server.com:8080/webservice-war/HostaliasSearchImplService?wsdl
which is obously wrong (Glassfish listens to port 8080). and also https is changed to http
Anyone an idea how I can fix it, that the automatically generated link is:
https://our.server.com/webservice-war/HostaliasSearchImplService?wsdl
BR, Rene

I discovered what I consider to be a very simple and elegant way to deal with the issue: use mod_substitute. Since those of us with this problem are already using Apache, and it's built in and simple, I liked this approach best.
I put a block similar to the below in one of my Apache conf files and found joy:
<Location />
AddOutputFilterByType SUBSTITUTE text/xml
Substitute "s|http://internal:8080/foo|https://external/foo|ni"
</Location>

Found the solution!
Anonym gave me a good hint about mod_jk. So here the complete configuration (for RHEL5).
First of all Download the mod_jk module for apache: http://archive.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.31/x86_64/
Put in in the modules directory /etc/httpd/modules and make it executeable:
chmod +x mod_jk-1.2.31-httpd-2.2.x.so
After that create /etc/httpd/conf/workers.properties:
# Define 1 real worker using ajp13
worker.list=worker1
# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009
The Port 8009 is the where the Glassfish jk connector listens (we come to that later).
No we have to configure mod_jk, therefore create the file: /etc/httpd/conf.d/mod_jk.conf with the following content:
LoadModule jk_module modules/mod_jk-1.2.31-httpd-2.2.x.so
JkWorkersFile /etc/httpd/conf/workers.properties
# Where to put jk logs
JkLogFile /var/log/httpd/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel debug
# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"
# Send everything for context /atsi-war to worker named worker1 (ajp13)
JkMount /yourapp-war/* worker1
(This means everything from your http://apache.webserver.com/yourapp-war/ will bi redirected to Glassfish yourapp-war application context)
Important, if you are using virtual hosts on apache, you have to set the option:
JkMountCopy On
for your virtual servers. Explication:
If this directive is set to "On" in
some virtual server, the mounts from
the global server will be copied to
this virtual server, more precisely
all mounts defined by JkMount or
JkUnMount.
Now we have to create the jk connecter in glassfish:
asadmin create-http-listener --listenerport 8009 --listeneraddress 0.0.0.0 --defaultvs server jk-connector
asadmin set configs.config.server-config.network-config.network-listeners.network-listener.jk-connector.jk-enabled=true
Restart Glassfish, and everything sould work.

As for rewriting the https -> http, I'm not sure that's possible(yet) without using mod_jk, see here
, but see also this little guide
Though, generally, you'll need configure Glassfish and set http.proxyPort (and probably http.proxyHost too). Hopefully that should reflect in the autogenerated WSDL URL.
Here's 3 different ways to do this:
1
Use asadmin (in the Glassfish bin/ directory, run
asadmin create-jvm-options "-Dhttp.proxyPort=80"
asadmin create-jvm-options "-Dhttp.proxyHost=our.server.com"
2
Edit domain.xml and add under the <java-config> element
<jvm-options>-Dhttp.proxyPort=80</jvm-options>
<jvm-options>-Dhttp.proxyHost=our.server.com</jvm-options>
3.
Open the Glassfish admin web page, under Application Server -> VM Settings -> JVM Options and add these options
http.proxyPort=80
http.proxyHost=our.server.com

Setting
server-config.network-config.protocols.protocol.http-listener-1.http.server-name=MyHost:80
on GlassFish Server Open Source Edition 3.1.2.2 (build 5) solved problem to me.
