Weird characters when deploying to tomcat

[bonsmik]

Overview of the issue

After deploying application to tomcat weird chars in application.   becomes  

Example from login page:

Motivation for or Use Case

Instead of using boxfuse to deploy I use jhipster aws subgenerator. Now I see those weird characters when running the application on Tomcat.

Reproduce the error

Create minimal application. Build the war as instructed. Deploy the application on tomcat. See login page.

Dockerfile for tomcat:

FROM tomcat:8.5-alpine

RUN cd webapps/ && rm ROOT -rf
ADD myapp-0.0.1-SNAPSHOT.war /usr/local/tomcat/webapps/ROOT.war

EXPOSE 8080

CMD ["catalina.sh", "run"]

Steps to reproduce:

./gradlew -Pprod -Pwar clean bootWar
docker build -f Dockerfile -t myapp ./build/libs
docker run -d -p 8080:8080 myapp:latest
open "http://localhost:8080/login"

I could not reproduce with Maven, but I could reproduce with Gradle, both Angular and React. The weird characters are present on the home page with no changes in the message: You don't have an account yet? Register a new account

I'm not familiar with Gradle so did not look into a fix.

For reference, here's the script I use for testing Tomcat (no database for easy Tomcat testing):

echo '{ "generator-jhipster": { "promptValues": { "packageName": "com.mycompany.myapp", "nativeLanguage": "en" }, "jhipsterVersion": "6.4.1", "applicationType": "gateway", "baseName": "nodb", "packageName": "com.mycompany.myapp", "packageFolder": "com/mycompany/myapp", "serverPort": "8080", "authenticationType": "uaa", "uaaBaseName": "uaa", "cacheProvider": "ehcache", "enableHibernateCache": false, "websocket": false, "databaseType": "no", "devDatabaseType": "no", "prodDatabaseType": "no", "searchEngine": false, "messageBroker": false, "serviceDiscoveryType": false, "buildTool": "gradle", "enableSwaggerCodegen": false, "clientFramework": "angular", "clientTheme": "none", "clientThemeVariant": "", "useSass": true, "clientPackageManager": "npm", "testFrameworks": [], "jhiPrefix": "jhi", "entitySuffix": "", "dtoSuffix": "DTO", "otherModules": [], "enableTranslation": true, "nativeLanguage": "en", "languages": [ "en" ], "embeddableLaunchScript": false, "blueprints": [] } }' > .yo-rc.json

Will have a look. Sounds strange indeed. Maybe some resource processing or so

I can't reproduce it on my machine.

Sorry, just added and   and I have the same error now.

[atomfrede]

I found a solution (the web.xml is missing from generated war). Will provide a PR tomorrow.
