My Eclipse project is suddenly no longer deploying properly   I can t trace it to any particular change I ve made to the environment   I have tested with multiple source-controlled projects and they

STS has a metadata folder under its workspace  You will see the actual error in  log file under C  Users firstname lastname Documents workspace-sts-3 9 2 RELEASE metadata

Watch out if you are using Maven  Your folder s structure must be right   When using Maven  the WEB-INF directory must be inside webapp   src main webapp WEB-INF

WebApplicationInitializer is an interface you can implement in one of your classes  At startup Spring is scanning for this classes  as long as you are using servlet spec 3 and have a metadata-complete  false  attribute in your web xml  But that doesn t seem to be the problem  The only error I can figure out is the missing slf4j-log4j12 jar

User · Answer

xml was not in the WEB-INF folder  thats why i was getting this error  make sure that web xml and xxx-servlet xml is inside WEB INF folder and not in the webapp folder

I also had the same problem  My maven had tomcat7 plugin but the JRE environment was 1 6  I changed my tomcat7 to tomcat6 and the error was gone

config   That said  I m all happy with myself now and know Maven and Spring much better for the next step of my Spring learning curve  Hoping this helps you also

I faced this problem and finally resolved  Please make sure that your web xml and Servlet xml file should present in web inf folder    Also Please add spring jars into Web Deployment assembly in project properties  We might missed out this when setting up the project from beginning

This turned out to be a stupid error   My log4j wasn t configured to capture my error output   I was throwing configuration errors in the background and once I fixed those I was good to go and my request mappings worked fine

INFO  No Spring WebApplicationInitializer types detected on classpath   Can also show up if you re using Maven with Eclipse and deploying your WAR using    Eclipse  Kepler  with M2    right-click on your project  -  Run As -  Run on Server  It s down to the generation and deletion of the m2e-wtp folder and contents   Make sure  Maven Archive generated files under the build directory is checked   Under   Window -  preferences -  Maven -  Java EE Integration   Then   Use M2  to do your build  i e  the usual Clean -  package or Install etc     If  Project -  Build Automatically  is not selected  You can force the  m2e-wtp folder and contents  generation by doing     right-click on your project  -  Maven -  Update Project      Note  make sure the  Clean Projects  option is un-selected  Otherwise the contents of target classes will be deleted and you re back to square one   Also when    Project -  Build Automatically  is selected the  m2e-wtp folder and contents  is generated  or  Project -  Build All   or   right-click on project  -  Build Project

tomcat-maven-plugin in test  Tomcat usually does not add classes in src test java to the classpath  They are missing if you run tomcat in scope test  To order tomcat to respect classes in test  use -Dmaven tomcat useTestClasspath true or add    lt properties gt      lt maven tomcat useTestClasspath gt true lt  maven tomcat useTestClasspath gt   lt  properties gt    To your pom xml

In my case it also turned into a multi-hour debugging session  Trying to set up a more verbose logging turned out to be completely futile because the problem was that my application did not even start  Here s my context xml   lt  xml version  1 0  encoding  utf-8   gt   lt Context path  quot  rc2 quot  docBase  quot rc2 quot  antiResourceLocking  quot false quot   gt       lt JarScanner gt           lt JarScanFilter             tldScan  quot spring-webmvc  jar  spring-security-taglibs  jar  jakarta servlet jsp jstl  jar quot              tldSkip  quot   jar quot               lt  -- my-own-app  jar on the following line was missing  -- gt              pluggabilityScan  quot   tomcat util scan StandardJarScanFilter jarsToScan   my-own-app  jar quot              pluggabilitySkip  quot   jar quot   gt       lt  JarScanner gt   lt  Context gt   The problem was that to speed up the application startup  I started skipping scanning of many JARs  unfortunately including my own application

I spent my whole day today investigating this problem and none of the answers helped  Here is my scenario  The WebApplicationInitializer types in my case are inside jar files  we have a multi-module gradle web project where each module is packaged as a jar and included in the web artifact  The problem is that Apache tomcat s classloader is not looking for the implementations of WebApplicationIntializer in WEB-INF lib instead its looking for those types directly under WEB-INF classes folder    Here is what I ended up doing for anyone who faces this problem in future    I implemented a ServletContainerInitializer myself and added that class name to META-INF services javax servlet ServletContainerInitializer  In the implementation  I copied the code from SpringServletContainerIntializer and used reflections to find the classes implementing a CustomWebApplicationInitializer interface  I did not make use of spring s WebApplicationInitializer interface to avoid any conflicts  Basically I have the same contract as WebApplicationInitializer with a different name  Now on startup  my container initializer is called and I delegated the call to all my CustomWebApplicationInitializers   Based on my search I also found that the loader used for tomcat can be updated to have it search in WEB-INF lib but I have little control over the tomcat I deploy my app to so went with the above solution  Hope this helps someone
