Vaadin-Spring + Spring security prevents WidgetSet addSessionInitListener

[gokhanoner]

I'm using vaadin-spring, Spring security 4. I have an HTML login page, after successfull login, my Vaadin app. is loading. Problem is, When WidgetSet init. after session creation, Vaadin Service is null. it's initialized after login.

What I did, I extended SpringVaadinServlet and override servletInitialized() method & added the listener and other params from WidgetSet.

Is there a better way to do it?

[gokhanoner]

Is there any workaround on this one ?

[mstahv]

Could you try with Vaadin 7.7.0.alpha3 (and its CDD mode for widgetset) ? That don't use web listener anymore, so it might work without workarounds.

I'm using like below but it doesnt compile the widgetset ? What am i missing?

        <plugin>
            <groupId>com.vaadin</groupId>
            <artifactId>vaadin-maven-plugin</artifactId>
            <version>${vaadin.plugin.version}</version>
            <configuration>
                <theme>gbtheme</theme>
                <warSourceDirectory>${basedir}/src/main/resources</warSourceDirectory>
                <widgetsetMode>local</widgetsetMode>
            </configuration>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>compile-theme</goal>
                        <goal>update-widgetset</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

btw, I removed <update-widgetset> and used cdnoption. still not working. + I need to be able to download the widgetset. Is fetch option designed for that ?

[mstahv]

I think both update and compile should(/can) be there. fetch mode just compiles the widgetset in the cloud, but hosts in from your war file.

Do you have some small example project I could try and debug?

[gokhanoner]

Just preparing a small example. But please correct me if I understand correctly:

• update-widgetset was used to create widgetset from .gwt.xml file, which I dont have. I'm using spring-boot + wscdn-maven-plugin based setup. And now removed the wscdn-maven-plugin and just added new config setup.
• I cannot see any error + anything that indicates that widgetset compilation is done.

[gokhanoner]

Update: I managed to make it work:

• local option wait for .gwt.xml.
• cdn options create the necessary AppWidgetset class. Only thing maybe is to create it inside a named package rather than the default apckage.
• fetch option works but I guess it needs a url to fetch it ?
• some logginng conf. warnings inside maven plugin.
• multiple theme compilations or, at least, logs.

Please see attched picture

[gokhanoner]

I looked to the source code. I suppose fetchdoesn't download, actually couldn't figure out what it's doing. And when I use the local option, it just creates a gwt.xml file. No compiled addons.

[samie]

That "Public URL: null" does not look right. Before that add-on detection goes ok.

[mstahv]

It works, it is just that the logging is invalid when the mode "fetch" is used.

I created an issue about this: https://dev.vaadin.com/ticket/19944

[gokhanoner]

Matti,

You sad it worked. In which folder the widgetset downloaded ?? And how can I control it ? Because it's a spring-boot setup, my app, it should be in a src/main/resources/VAADIN/widgetsets folder

[mstahv]

Those are generated resources and should NOT go under src directory . By default those go to target/classes/, where they are served by the VaadinServlet, also in Spring Boot based app.

[gokhanoner]

This is target/classes folder, I can see AppWidgetset.class file, but cannot see compiled widgetset files , js files ? And in my case, addons are not working.

[mstahv]

Remove your warSourceDirectory configuration and execute "mvn clean install"

[gokhanoner]

Below is the current config. It's still same. widgetset created/downloaded to anywhere.

        <plugin>
            <groupId>com.vaadin</groupId>
            <artifactId>vaadin-maven-plugin</artifactId>
            <version>${vaadin.plugin.version}</version>
            <configuration>
                <theme>gbtheme</theme>
                <!-- <warSourceDirectory>${basedir}/src/main/resources</warSourceDirectory> -->
                <widgetsetMode>fetch</widgetsetMode>
            </configuration>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>compile-theme</goal>
                        <goal>update-widgetset</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

[mstahv]

You are missing the compile goal:

<goal>compile</goal>

[gokhanoner]

Perfect. Now it's working. Thanks for help & advice. Hope to see 7.7.0 GA in near future.
