Tomcat runner ignores config file based realm configuration

[juanitocalero]

Using tomcat as my container, if I specify a custom realm in tomcat.xml two things can happen:

• If i provide the tomcat-users.xml file, Gretty picks this up and configures automatically a fixed realm, losing my custom configuration.
• If I don't provide the file, Gretty ignores my custom configuration.

The workaround I found is leaving the tomcat-users.xml present, and provide a realm configuration in webapp context.xml file.

I think the error comes from this code in TomcatServerConfigurer.groovy:

    def realmConfigFile = webapp.realmConfigFile ?: params.realmConfigFile
    if (realmConfigFile && new File(realmConfigFile).exists()) {
      log.info '{} -> realm config {}', webapp.contextPath, realmConfigFile
      def realm = new MemoryRealm()
      realm.setPathname(realmConfigFile)
      context.setRealm(realm)
    } else
      context.addLifecycleListener(new FixContextListener())

    context.configFile = tomcat.getWebappConfigFile(webapp.resourceBase, webapp.contextPath)
    if (!context.configFile && webapp.contextConfigFile)
      context.configFile = new File(webapp.contextConfigFile).toURI().toURL()
    if (context.configFile)
log.info 'Configuring {} with {}', webapp.contextPath, context.configFile

I believe that context.addLifecycleListener(new FixContextListener()) makes Tomcat ignore further configuration

I have the same problem if I use a DataSourceRealm in my context.xml. I must set an empty file to make it works.

Here my gretty configuration:

gretty {
    servletContainer = 'tomcat8'
    enableNaming = true
    contextPath = 'app'
    realmConfigFile = 'empty.xml' 
    
    dependencies {
        // https://mvnrepository.com/artifact/org.apache.tomcat/tomcat-dbcp
        gretty 'org.apache.tomcat:tomcat-dbcp:' + tomcat8Version
        // https://mvnrepository.com/artifact/com.microsoft.sqlserver/sqljdbc4
        gretty 'com.microsoft.sqlserver:sqljdbc4:4.0'
        // https://mvnrepository.com/artifact/org.clojars.prepor/vertica-jdbc
        gretty 'org.clojars.prepor:vertica-jdbc:7.0.1-0'
        // https://mvnrepository.com/artifact/org.hsqldb/hsqldb
        gretty 'org.hsqldb:hsqldb:2.4.0'

    }
