To the Debugging with Chrome:
- Actually you still could read the variable name because it is readable... and you can add your variable to the watcher and it's all readable... Just try it.
- To run Jetty (included in GWT) just use Maven cmd "mvn gwt:generate-module gwt:devmode". You can do this inside NetBeans or outside from NetBeans, makes no difference.
- After you change your code NetBeans will compile the Java code, you don't need to stop the Jetty. Just reload your webapp in Chrome browser and GWT transpiler will transpile your changed Java code (incremental), very fast. So, do not restart your Jetty. Chrome will show the changed code after the reload.
To be able to do this you need to separate the projects:
So you are able to just use the integrated Jetty from GWT and you don't need the "server" part. You'll find lot of advantages to separate those modules. It is later easier to upgrade to the newer version of GWT and you don't have "classpath hell".
The easiest thing to test the complete cycle of your webapp is to run two web containers:
- Jetty web container for the client part. This is integrated in GWT, see this screenshot: http://www.gwtproject.org/images/myapplication-devmode.png
- On the server you just use the web container which you need:
- If you are using Spring Boot, just use it.
- If you are using JBoss / WildFly just use it.
The client (web browser with HTML, JS and CSS) accesses the server (Servlet, ...) with remote procedure anyway (GWT RPC, REST, ...). So it's ok to run 2 processes in the development time. In the deployment time later, you could "copy" the result of the client (HTML, CSS, JS) to the root directory of your web container, so that you could just run one process.
Remember, the result of the "client" part is only HTML, JS, CSS and other resources.
With this in mind you could begin to restructure your one huge project into 3 projects.
You have NetBeans Connector for Chrome: https://chrome.google.com/webstore/detail/netbeans-connector/hafdlehgocfcodbgjnpecfajgkeejnaa?utm_source=chrome-ntp-icon
So, no need to change your IDE 😉👍
Hope this helps.

That is why we need to change the IDE on this stage if need to be get upgraded. our team has expertise on NetBeans and we don't want to change IDE, but we don't have any option.as you have suggested:(1) Directly debug in Chrome, the easiest one but with some problem with variable names. I found this one is good enough for me, see: https://miro.medium.com/max/1400/1*zeTE0robP4_HQ2gc6WAVUQ.pngWe are having a quite big project and we guise debugging in chrome itself will not help us because of variable names (as you also noticed) etc.But if we keep the problems aside and just want to see how it works using NetBeans can you share any link or tutorial for that. Because we don't think it will run without GWT plugin.This is what we understood by your example:1. creating a client code in NetBeans and run that code by pressing CTRL+F5 or by any way.2. Run our application on chrome by hitting URL: http://localhost:8080/myGWTapp3. Debug the code using chrome inbuilt debugger.4. If bug found then stop the server and do the changes in NetBeans and again repeat the process from Step-1.how this will show the java code on chrome inBuilt debugger.Open dev toolsCtrl+O → start typing GwtProjectEntryPoint.java, then enterJava source for that class opens in the sources tab and you can set breakpoints here and debug the website.This is because the website has been deployed with sourcemaps and a copy of the sources.(2) Try to run the debugger on Chrome in your IDE. For this to work your IDE needs to have Chrome Web Browser Plugin (IntelliJ Ultimate and Eclipse have this). Here is an example doing this in IntelliJ: https://gist.github.com/hpehl/bd00b22586d0c75d37d5fe7f0cfcd823 (never tried this by myself)if it comes to change the IDE then in that case we will opt Eclipse. The link provided by you is for IntelliJ only.(3) In Eclipse you have the plugin SDBG (which is actually the extension of (2)): https://sdbg.github.io (never tried this by myself)Yes we are trying to prepare a development environment for SDBG in Eclipse but we are facing some issues.1. It is forcing us to use JETTY as a server. but as we have already mentioned that we are having a big project and usingclient, shared, server all module in same project. means we have not separated the client & server code yet.so we cannot depend of JETTY we want to use server of or choice.2. Because our project is big. So for maintenance point of view we have broken the project into many small - small jars and finally we include that jar files in a web project and build a single war file.All is going well, when we start debugging via SDBG and use super dev mode browser starts the compilation automatically and we are also able to debug it via Eclipse.if we need to do any changes we can do it on Eclipse and just need to refresh the browser without restarting the server and it compiles the code well and reflects the changes made.But if we do the changes in the JAR files, compile them and then try to refresh the browser it do not reflect the changes.Does this means super dev mode will work only in case of single web project, To reflect the changes done in external files we need to restart the server again. if so then there will be no use of super dev mode for us (in terms of speed, compilation & development both).Please help us providing a better way so that we could upgrade or applications from GWT 2.6.1 to latest 2.9.0.Now we are feeling stucked ....On Wednesday, September 30, 2020 at 2:34:27 PM UTC+5:30 lofid...@gmail.com wrote:Debugging with the old client is dead, because of changes from web browser, so at the end you have to migrate to Super Dev Mode.It's a pitty that NetBeans still hasn't support the new Super Dev Mode but there are workarounds:(1) Directly debug in Chrome, the easiest one but with some problem with variable names.

September 2020 um 09:51:00 UTC+2:Thank You Frank & Lofi for your guidance.We will analyze the links provided by you and revert you back what we experience on that.But the point where we have a doubt is, currently we use GWT 2.6.1 plugin for netbeans and are able to debug a client source in netbeans it self.By marking a breakpoints in client source on netbeans, browser automatically communicate with netbeans because of (browser GWT plugin & netbeans GWT plugin).Browser transfers the control on the break point already marked in netbeans and from there we can debug our code (using F7, F8 keys) in netbeans itself.Will we get this type of functionality after moving to maven or whatever, as you suggest.We just want to know how will we able to debug our client source in java same as previous.On Tuesday, September 29, 2020 at 3:05:53 AM UTC+5:30 lofid...@gmail.com wrote:NetBeans has a very good Maven support. So you can do everything with Maven, also in NetBeans. With Maven you are IDE independent:Introduction to Maven:
- Introduction to Maven: https://www.baeldung.com/mavenAfter you know how to work with Maven...
- Take a look at this article: http://bit.ly/WebJavaStory
- ... with this simple example: https://github.com/lofidewanto/jsinterop-simple-example
- Checkout the example and run it as it explained in the README.MD
- You can try to run the example... debug it... just like what the article shows you.Maven plugin for GWT:
- There is one and only Maven plugin you should use: https://github.com/tbroyer/gwt-maven-plugin.It is worth it for everyone to learn Maven to build you project, so you are IDE independent.Also you can take a look at this presentation to understand the anatomy of GWT web apps: https://bit.ly/gwtintropresentationIf you have done the Maven stuffs you can use the Project Generator which Frank showed above. The important part IMHO is to understand what Maven gives you and how you can use Maven to build your project first.Hope this helps.Lofiviny...@gmail.com schrieb am Montag, 28.

hi Lofi,we are also having same problem. we are using:1. 2.6.1 GWT version.2. netbeans as a GUI with GWT plug in (which helps in debugging Source (SDBG))but now, we want to switch to newer or latest version of GWT 2.9.0 but there is no plugin for netbeans yet.Instead there is a eclipse plugin, so we don't have any option, we just have to move on eclipse (provide the training to team and understanding the eclipse functionality etc.).reading your answer seems that we can use maven for all things. But as we always worked on netbeans we don't know how can we configure, develop, debug etc. the GWT project in maven.can you please help us or share any document which can help us understanding the GWT project configuring in MAVEN.On Saturday, September 12, 2020 at 3:12:16 PM UTC+5:30 lofid...@gmail.com wrote:@Craig: Oh I don't know that Eclipse Plugin...

I always use pure Maven and if you are familiar with Spring Boot, I've developed similar mechanism GWT Boot (at the moment without the Initializr, but I'm planning to do that).... with all examples available just like Spring Boot... All still ini SNAPSHOT, so if you are working behind a firewall in your company you need to add the Sonatype Snapshot:<repositories><repository><id>sonatype-snapshots</id><name>Sonatype Snapshots</name>...Please see: https://github.com/gwtboot/gwt-boot-samplesFor me it is always easier just to work with Maven and I could choose my IDE (Eclipse, IntelliJ or VSC for Java).Hope this helps.LofiCraig Mitchell schrieb am Samstag, 12.
