The script load being injected is a workaround for the limitation in GWT 2.7.0 that causes <script> tags to be ignored. In our SGWT Showcases and the BuiltInDS Sample Project the main page is in the war directory (parent folder), so the document write is designed to create script directives paralleling those in that (the main) page. This is the first we've heard of the main page being in an alternative location.

We are looking into it.

**wildex999** · 5 Aug 2016, 00:22

The structure of the war folder for me is something like this:
war/
- com.code.transcoder/
- - ace/
- - images/
- - sc/
- - ...
- - ....gwt.rpc
- - com.code.transcoder.devmode.js
- - com.code.transcoder.nocache.js
- - loadScriptTagFiles.js
- - ...
- com.code.transcoder.JUnit/
- - .junit_symbolMaps/
- - ace/
- - images/
- - sc/
- - ...
- - ....gwt.rpc
- - com.code.transcoder.JUnit.devmode.js
- - com.code.transcoder.JUnit.nocache.js
- - ...
- - junit.html
- - loadScriptTagFiles.js
- images/
- WEB-INF/
- index.html
- transcoder.css

The junit.html file has an older "Date modified" than the other files, but still seems to be re-generated at that location if it's deleted.

Thank you for taking the time to look into it =)

It sounds like you're saying that both hierarchies of files are created (during GWT compilation) from a single module specification file (presumably com.code.transcoder.gwt.xml), is that correct? Or do you have a separate manually-coded gwt.xml file for the com.code.transcoder.Junit module hierarchy?

**wildex999** · 8 Aug 2016, 04:00

We only have a single module yes: com.code.transcoder.gwt.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.6.1//EN" "file:////opt/gwt-2.6.1/gwt-module.dtd">

<entry-point class='com.code.transcoder.Main'/>
</module>

As far as I know, we do nothing extra to generate or change the JUnit part.
com.code.transcoder.Junit seems to be generated when we run the tests.

**Isomorphic** · 8 Aug 2016, 06:15

Can you provide the command line you're using to generate or run the tests - or a description of the required GUI tool interaction? Are you saying that the "extra" JUnit hierarchy is not created when you compile the module (e.g. "ant build") but only later when you actually explicitly trigger a run? Are you running the tests in production or (Super)Development Mode?

**wildex999** · 8 Aug 2016, 07:13

Ah, knew I forgot to mention something. We run everything using gradle:

Code:

apply plugin: 'java'
apply plugin: 'checkstyle'

repositories {
    maven {
        url 'http://nexus.internal/content/groups/trunk/'
    }
}

dependencies {
    compile 'com.isomorphic.smartgwt.lgpl:smartgwt-lgpl:5.1-p20160708'

    compile 'com.google.gwt:gwt-user:2.7.0'
    compile 'com.google.gwt:gwt-dev:2.7.0'

    testCompile 'junit:junit:4.11'
}

test {
    testLogging.showStandardStreams = true
    systemProperties = ['gwt.args': '-logLevel WARN']
    // Gwt tests require src/test dirs on classpath.
    classpath += files(sourceSets.main.java.srcDirs,
                       sourceSets.test.java.srcDirs)
}

task testWeb(type: Test) {
    testLogging.showStandardStreams = true
    systemProperties = ['gwt.args': '-web -logLevel WARN']
    // Gwt tests require src/test dirs on classpath.
    classpath += files(sourceSets.main.java.srcDirs,
                       sourceSets.test.java.srcDirs)
}

clean {
    delete 'war/WEB-INF'
}

task compileGwt(type: JavaExec,  group: 'GWT', dependsOn: [classes]) {
    main 'com.google.gwt.dev.Compiler'
    classpath files(sourceSets.main.compileClasspath,
                    // Gwt compile requires source dirs on classpath.
                    sourceSets.main.java.srcDirs)

    args = ['com.code.transcoder', '-style', 'PRETTY']
}

task codeserver(type: JavaExec,  group: 'GWT', dependsOn: [classes]) {
    main 'com.google.gwt.dev.DevMode'
    classpath files(sourceSets.main.compileClasspath,
                    // Gwt compile requires source dirs on classpath.
                    sourceSets.main.java.srcDirs)
    args = ['-superDevMode', '-port', '8889', '-startupUrl', 'index.html', 'com.code.transcoder']

}

task warCleanup (type: Delete) {
    mustRunAfter compileGwt

    delete 'war/com.code.transcoder/sc/schema'
    delete 'war/com.code.transcoder/sc/system'
}

build {
    dependsOn compileGwt
    dependsOn warCleanup
}

Running just 'gradle compileGwt' or 'gradle codeserver' does not create the JUnit hierarchy.
Running 'gradle test' does however create it.
We also try running the tests from Eclipse directly, but it gives the same errors.

As far as I see, we do nothing 'extra' for the JUnit part. Removing JUnit as a dependency for the testCompile, does stop the directory from being created, but all the tests also fail instantly, so that might not tell much.
However, switching back to an older SmartGwt version does fix it(It doesn't seem like you use loadScriptTagFiles.js at all in the previous version we used.)

**Isomorphic** · 8 Aug 2016, 08:29

Are you able to see output similar to the following in your log files for the com.code.transcoder.JUnit module? You'll know that it applies to that module because above it some number of lines it will say:

OK. We'll be making an initial change to verify that the configuration properties defined in your gwt.xml are available to our linker in the automatically generated module. If so, we should be able to provide a fix.

**Isomorphic** · 9 Aug 2016, 15:44

OK. If you could update to today's build (2016-08-09) or later of SGWT 5.1p, and add the following to your com.code.transcoder module definition file (gwt.xml):

Code:

 <set-configuration-property name="scriptInjector.testProperty" value="test1" />

Let us know if you see the test output when the com.code.transcoder.JUnit module is built. (You posted earlier the section of the log that would contain this output.)

**wildex999** · 10 Aug 2016, 01:28

Yes, it seems to output during the test compile:

We've applied a configuration capability to SGWT 5.1p and newer that will let you set the expected path of the module directory relative to the root HTML page. It will be in the nightly builds dated 2016-08-12 and beyond.

Example usage of the new configuration capability has been added to the BuiltInDS Sample Project included in the SGWT EE Showcase. Based on what you've said above, for you the lines you'll need to add to your gwt.xml file are:

Code:

<define-configuration-property name="scriptInjector.pageRelativeModulePath" is-multi-valued="true"/>
<extend-configuration-property name="scriptInjector.pageRelativeModulePath" value="com.code.transcoder.JUnit=."/>

Additional bindings can be added if needed, of the form <module name>=<relative path>. If no binding is present for a module than the default relative path is assumed.

**wildex999** · 12 Aug 2016, 05:52

Yes, that fixed the problem with loading the javascript files.
There still seems to be other places which still get's the wrong path. For example Page.getIsomorphicDir() and the special [ISOMORPHIC] path prefix still returns the wrong path, which causes our skin files to fail loading:

Code:

404 - GET /com.code.transcoder.JUnit/com.code.transcoder.JUnit/sc/skins/code/skin_styles.css

For the tests this isn't really a problem, as they run anyway, but the warnings cause a lot of spam.

Anyway, Thank you for taking the time to look into this and provide a fix =)

**Isomorphic** · 12 Aug 2016, 16:14

The value of isomorphicDir is typically set by the HTML page before the <module>.nocache.js file is loaded. Can you post the content of the junit.html file?
