I've built a spring boot application and I'm trying to customize the banner to display the version of my application.
After reading the documentation, I've managed to create a banner.txt in the classpath and added the ${application.formatted-version} placeholder inside.
I've also managed to create a manifest file (using Gradle) containing the Implementation-Version.
Everything works fine when executing a jar file directly but when creating a war file, the banner is displayed but the version placeholder is not replaced.
After a bit of debugging, this method seems to be the source of the problem
org.springframework.boot.ResourceBanner.getApplicationVersion()
When running a war file, the call to
sourcePackage.getImplementationVersion() always return null
The manifest file is located at the root of the war file /META-INF/MANIFEST.MF
The application is deployed in a standalone tomcat 8.0.15
Any idea of what's wrong ?
It's a bug/limitation in Tomcat. It fails to find the /META-INF/MANIFEST.MF from an exploded WAR file which causes its ClassLoader to define the package with a null implementation version. This has been fixed in Tomcat, but the fix hasn't made it into a release yet. It'll be in 8.0.25.
There's some more information in this Spring Boot issue and this is the change that was made to Tomcat if you're interested.

I have created a spring project with maven and it works fine. I am trying to add a jar file to the project, eclipse does not give any errors but when i start the server and try to access to the page which uses a class from that jar file i get a classNotFound exception.
My steps are..
1 - I put the jar file in src->main->resources
2 - I added it to build path by right clicking and saying add to build path.
3 - I add the project to tomcat and start the server
The thing is i looked at the tomcat deployment directory and the .jar file appears in classes directory. When i take copy the file from classes to lib (which has libraries downloaded by maven) project works fine.
I just changed the output delivery as jar instead of war inside the pom.xml. But now, I've don't manage to load the login page. Not displayed. Cf. screenshot.
What should I do to make "One file delivery" ?
Thanks
Error loading login page
Resolved.
In fact, it is not needed to change to jar output. The generated war is already executable. (like jar command : java -jar your.war).
Maven spring boot plugin outputs 2 war files : xxx-0.0.1-SNAPSHOT.war and xxx-0.0.1-SNAPSHOT.war.original. The former contains tomcat embedd librairies (and more differences) and then it is the executable one. The latter contains old fashion war file : to be put into an external servlet container.
Thanks.
My application is running on Tomcat 7.
I'm trying to read emails from inbox, and for that I use a normal Java class.
There is also a Servlet that calls the method readMails in the mentioned class.
Now I get an exception:
java.lang.ClassNotFoundException: javax.mail.MessagingException
...
I use IntelliJ IDEA with Maven, I changed the dependency of javax.mail a lot (see http://mvnrepository.com/artifact/javax.mail), but the exception keeps coming up.
I've also changed the Version of Tomcat (7 and 8), and the version of "Project SDK" (1.7 and 1.8) and "Project language level" (7 and 8).
I've read somewhere that there is a difference between reading emails via IMAP with normal Java application and running it on Tomcat.
In a previous project I read emails successfully with a normal Java application.
Can anyone help me with this exception?
JavaMail API is not included by default among Tomcat libraries.
Make sure that JavaMail dependency (mail-X.X.jar) is either packaged together with your application (in WEB-INF/lib) or is in a folder that Tomcat class loaders read (for example $CATALINA_HOME/lib), as described here:
http://tomcat.apache.org/tomcat-7.0-doc/class-loader-howto.html
Thanks, it works now.
I put the jar file (javax.mail: javax.mail-api-1.5.4.jar) downloaded by maven (.m2/repository/ ...) into WEB-INF/lib (in my project).
I also needed to put another jar file into WEB-INF/lib (com.sun.mail: javax.mail-1.5.4.jar) due to this exception:
java.lang.NoClassDefFoundError: com/sun/mail/util/MailLogger
javax.mail.Session.initLogger(Session.java:226)
javax.mail.Session.<init>(Session.java:210)
javax.mail.Session.getDefaultInstance(Session.java:321)
I added
<packaging>war</packaging>
to my pom.xml. This way maven puts the dependencies in the target folder.
I am working on an maven application. When I run it from IntelliJ, it successfully launches my application. But bootstrap.groovy file is not being read. I have created a new username to be added to DB in bootstrap and it should allow me to login to the application using that username for the first time. This is not getting invoked during the start of the program. What settings should I do to include bootstrap.groovy.
The same happens when I create a war file and deploy it in the test server. Bootstrap.grrovy is not read. To create the war file, I use mvn package in command line.
My other question with the same application is that when I do grails run-app, I get the following error: Error generating web.xml file.
What is that I am missing? Please let me know.
Well, I fixed the issue. The web.xml was created when I changed the grails dependent jar. I was using 2.3.4 in my application and my jar was incompatible as I had 2.4.3 version of the jar. Now my program is up and running! Hope this helps someone who is facing the same problem.
So I have a grails 2.0.4 application that works exactly the way I want. I created the war file and deployed it to Tomcat 7. I'm getting an error saying that the application can't find the jar I'm using to connect to oracle (ojdbc6.jar). The jar is listed under mywebapp/WEB-INF/lib. WHY can't it be found?? Any help would be greatly appreciated!
The jar file should be in the toplevel lib directory of your project (or specified as a dependency in a repository), not webapp/WEB-INF/lib. Is the jar file actually inside the warfile? You can test this by opening the war as a zip file, or by running jar tf target/mywebapp*.war and looking for ojdbc6.jar. If it is, it should get deployed and you should see it in tomcat7/webapps/mywebapp/WEB-INF/lib.
The default environment for grails war is production instead of development. Make sure you've got the production data source configured correctly in grails-app/conf/DataSource.groovy
