You can safely skip step 0 in that document (I think that needs to be updated). And start at step 1. The document explains quite well what to do, but the short version is: 1. cd into the source code directory of either webadmin or user portal. Usually: ovirt- engine/frontend/webadmin/modules/(webadmin or userportal-gwtp) 2. mvn gwt:debug -Pgwtdev,gwt-admin,gwt-user -Dgwt.noserver=true from the command line. Once it is done compiling it will tell you it is listening on port 8000. 3.In eclipse (or your favorite java IDE) make a remote java application connection to port 8000 4. Once connected this will open up a GWT debug window. 5. In your browser as ?gwt.codesvr=127.0.0.1:9997 to the url you are working with and refresh the page. 6. It will either ask you to install the plugin in your browser or load the page depending on if you have the plugin already. Alexander

The GWT debugger is connected to the browser, not the server. The host page can be served from a local JBOSS, a remote Apache, a file, whatever. The GWT debugger doesn't care as it is talking to the browser. IMO the only thing we could do to improve this is update the make file to provide a target to start the debugger, which basically just calls maven with the appropriate parameters.

One of the ways is to have the GWT debugger spin up an instance of jetty and have your web application deployed in it. Then have it launch a browser with the appropriate url in it. Adding the --gwt.noserver on the command line tells GWT you don't want to spin up the jetty server, that the application you are working with is somewhere else and you will manually go to it. When the application is running normally it is all just javascript running in the browser. There are 'log' statements in the code but no loggers to write the data to. When you are connected to the browser with the GWT debugger the GWT debugger provides a logger to write to. In the old environment JBOSS. in the new environment nothing as JBOSS is listening on 8080 and 8443

Hi Alon, revisiting this thread, I have some comments regarding GWT debugging via standard development environment, as described in README.developer. - README.developer says: For example, if your machine is low on memory, use: EXTRA_BUILD_FLAGS_DEV="-Dgwt-plugin.localWorkers=2" however this should be: For example, if your machine is low on memory, use: EXTRA_BUILD_FLAGS_DEV="-Dgwt.compiler.localWorkers=2" - README.developer says: By default, only the gecko1_8 support is built I'd rather explain what this means: By default, only the gecko1_8 (Mozilla Firefox) support is built - what's the point of having EXTRA_BUILD_FLAGS_DEV_GWT vs. EXTRA_BUILD_FLAGS_DEV ? if EXTRA_BUILD_FLAGS_DEV_GWT is meant to control target browser(s) then it should be renamed appropriately if EXTRA_BUILD_FLAGS_DEV_GWT is meant to group all GWT-specific flags, README.developer shouldn't advise to do EXTRA_BUILD_FLAGS_DEV="-Dgwt..." - Makefile gwt-debug target looks OK to me gwt-maven-plugin must be invoked in context of a specific Maven module representing GWT application you want to debug. In other words, you need to start GWT Development Mode for specific application module. This is why you need to "cd" to specific directory (webadmin/userportal-gwtp) before invoking "mvn ... gwt:debug" command. You cannot start GWT Development Mode in a generic (application-agnostic) way and *then* connect to it from browser and Java IDE, this is not how GWT Development Mode is meant to be used. JBoss remote socket debugging and GWT application debugging are two different things. gwt-maven-plugin is just a wrapper to invoke GWT Development Mode (Java class). Regardless of how you start GWT Development Mode, you need to specify which application (more precisely, GWT modules) you want to debug right when starting GWT Development Mode. See [1] - "module(s)" are always specific for given application. [1] https://developers.google.com/web-toolkit/doc/latest/DevGuideCompilingAnd... Yes, as described in [2], besides using "gwtdev" profile for debugging, it can also be used for GWT compilation (i.e. "make install-dev") - in this case, resulting JavaScript will be un-obfuscated and not-too-optimized in order to easily profile the JavaScript application in the browser. In other words, using "gwtdev" for GWT compilation has nothing to do with debugging, maybe we should create separate profile for this purpose.

----- Original Message ----- Thanks! I +2'ed your patch [http://gerrit.ovirt.org/#/c/15827/] I see, so developer should only use EXTRA_BUILD_FLAGS_DEV to provide any additional settings (or override existing settings), i.e. both GWT and non-GWT settings can be customized via EXTRA_BUILD_FLAGS_DEV. If I understand correctly, EXTRA_BUILD_FLAGS_DEV_GWT is used internally for: - setting default target browser to Firefox (only) - enabling draft compile (if DEV_BUILD_GWT_DRAFT == 1) We can consider renaming EXTRA_BUILD_FLAGS_DEV_GWT -> EXTRA_BUILD_FLAGS_DEV_GWT_DEFAULTS. But in any case, I suggest to apply EXTRA_BUILD_FLAGS_DEV_GWT *before* EXTRA_BUILD_FLAGS_DEV (instead of the opposite like today). This way, EXTRA_BUILD_FLAGS_DEV can be used to override any settings set by EXTRA_BUILD_FLAGS_DEV_GWT. For example: $(MVN) \ $(EXTRA_BUILD_FLAGS_DEV_GWT) \ --> GWT-specific defaults $(EXTRA_BUILD_FLAGS_DEV) \ --> generic overrides (both GWT and non-GWT) ... install \ EXTRA_BUILD_FLAGS="$(EXTRA_BUILD_FLAGS_DEV_GWT) $(EXTRA_BUILD_FLAGS_DEV)" \ --> this one is OK Let me know what you think about this. +1'ed this patch. Right, please see my suggestion above. This would be problematic because when you invoke Maven on root pom, Maven only sees root pom classpath/artifacts, and we need Maven/GWT-Plugin to see application-specific classpath/artifacts. I'm not saying this is impossible, I'm just saying it will be much harder to do than just "cd" to webadmin/userportal-gwtp directory and invoking Maven there.. We could introduce new flags like DEBUG_GWT_WEBADMIN [0/1] which would take care of providing correct settings to gwt-maven-plugin, not sure if it's really worth it, because we already have DEBUG_MODULE and Makefile internally cd's to it. Yes, basically you need to specify all "modules" that make up for one application at time when you start GWT Development Mode. So GWT Development Mode, once started, is tied to specific application. OK, I'll make a patch to introduce "gwtdraft" profile with following effects once activated (via -Pgwtdraft): - set draftCompile to true -> prevent JavaScript code optimizations - set style to DETAILED -> produce pretty JavaScript without obfuscation After this, I suggest to modify Makefile so that DEV_BUILD_GWT_DRAFT=1 activates "gwtdraft" profile, instead of just doing -Dgwt.draftCompile=true

----- Original Message ----- After http://gerrit.ovirt.org/#/c/15736/ gets merged, I can make a patch that modifies this: DEV_BUILD_FLAGS:=$(DEV_BUILD_FLAGS) $(DEV_EXTRA_BUILD_FLAGS) DEV_BUILD_FLAGS:=$(DEV_BUILD_FLAGS) $(DEV_EXTRA_BUILD_FLAGS_GWT) to this: DEV_BUILD_FLAGS:=$(DEV_BUILD_FLAGS) $(DEV_EXTRA_BUILD_FLAGS_GWT) DEV_BUILD_FLAGS:=$(DEV_BUILD_FLAGS) $(DEV_EXTRA_BUILD_FLAGS) otherwise, it looks good to me.
