How To Setup Logback with Tomcat 6 on Windows - windows-7

I have tomcat6 installed on my Windows desktop for testing purpose. At the moment nothing is added to the webapps folder, just the normal tomcat start up. Following log files are produced:
catalina.2011-12-24.log
host-manager.2011-12-24.log
jakarta_service_20111224.log
localhost.2011-12-24.log
manager.2011-12-24.log
stderr_20111224.log
stdout_20111224.log
My problem is simple, I want these logs [stdout included] to be rolled and compressed on the basis of defined size limit.
I have read about logback and its capabilities to roll and compress files with defined policies, but I have not been able to make it work for me. I have copied following jars in $TOMCAT_HOME/lib directory:
logback-access-1.0.0.jar
logback-classic-1.0.0.jar
logback-core-1.0.0.jar
Some sites suggested these libs should be added as well:
jul-to-slf4j-1.6.4.jar
slf4j-api-1.6.4.jar
I have tried copying logback.xml in $TOMCAT_HOME/conf and $TOMCAT_HOME/lib, but unable to make it work.
I would really appreciate if someone can help me with this, best could provide me with a logback.xml and jars/xml location where these files should be copied to make it work.
P.S. I have not deployed any webapp in the tomcat, it just the basic tomcat setup.

I think this tutorial can help. Tomcat 6 works only with log....0.9.30.jar or lower. Tomcat + SLF4J + Logback

Sphinx4 breaks on AWS Elastic Beanstalk, works on dev machine

I created a dummy Maven project that wraps CMU Sphinx4 in a servlet. The dependencies are sphinx4-core:1.0-SNAPSHOT and sphinx4-data:1.0-SNAPSHOT. When running locally (Eclipse) it works great, but then I deploy it to AWS Elastic Beanstalk and I get the following exception:
Property exception component:'null' property:'null' - java.io.FileNotFoundException: JAR entry edu/cmu/sphinx/models/en-us/en-us//means not found in /var/lib/tomcat8/webapps/ROOT/WEB-INF/lib/sphinx4-data-1.0-SNAPSHOT.jar
edu.cmu.sphinx.util.props.PropertyException: java.io.FileNotFoundException: JAR entry edu/cmu/sphinx/models/en-us/en-us//means not found in /var/lib/tomcat8/webapps/ROOT/WEB-INF/lib/sphinx4-data-1.0-SNAPSHOT.jar
Caused by: java.io.FileNotFoundException: JAR entry edu/cmu/sphinx/models/en-us/en-us//means not found in /var/lib/tomcat8/webapps/ROOT/WEB-INF/lib/sphinx4-data-1.0-SNAPSHOT.jar
I suspect it's that double slash in there but I cannot explain why it doesn't happen on my dev machine (OSX).
thanks!
Edit:
My dev machine: OSX running Eclipse Luna with AWS plugin. I am using a J2EE project with a single servlet, and getting Sphinx JARs (core & data) through Maven. When I run the server in my dev machine (port 8080) I feed it a WAV file through a POST message, the file gets loaded correctly and I get the analysis as a textual response.
My prod machine: AWS Elastic Beanstalk. I deploy using AWS plugin. When I comment out the Sphinx part of the code, the server works (i.e. gets the file, and returns it to me, etc.)
If the problem is not the double slash, then the JARs are not being cooked right. This would make sense since the file it's looking for is not a class so the JAR cooking part of Maven should be told how to include resource files in the JAR it makes when it deploys.
Any idea how to do this ?
thanks again!
Double slash seems to be a problem on some JVMs, on other JVMs it works.
I've just committed an update to avoid double slashes. Please update sphinx4 and try again.
Turns out the problem was I was developing (OSX) on Java 7 and deploying to AWS to Tomcat/Java 8. Once I deployed to Tomcat/Java 7, everything worked as expected.

jboss-as-maven-plugin: which directory does command "jboss-as:deploy" deploy an .ear to?

I am running jboss 7.1, maven 3, and a java ee6 application that generates an .ear
I am doing a mvn clean package jboss:as-deployand Jboss-as-maven-plugin 1.5 does its thing--I can view my app using http://localhost:8080...
just fine, but I want to know where the actual .ear is being put.
It is not in my jboss7.../standalone/deployments folder. So where is it? My app is obviously running in jboss 7.1 just fine, but I can't find the .ear file. I know that there is an .ear in Eclipse's 'target' directory, but that wasn't produced by jboss-as-maven-plugin is it? I hope you can understand my confusion--don't all .ear files need to be in the deployments directory? I also do see my .ear file inside my hidden .m2/repository directory, but does this have any interaction with jboss-as-maven-plugin? Maybe there is some hidden sym-linking between my Eclipse project's 'target' directory and the jboss7.1 standalone/deployment directory?
p.s. I am used to using a hard-deploy option with the other plugin jboss-maven that requires you to say jboss:hard-deploy which just copies the .ear to your deployments folder. Then jboss would pick up the new .ear and redeploy automatically. I get the sense that jboss-as-maven-plugin is the preferred plugin so that's why I am bothering.
The jboss-as-maven-plugin uses the deployment API so it doesn't copy the file to the deployments directory for the scanner to pick it up. It deploys just as if you deployed it from the web console or via CLI. The files should be located somewhere in the $JBOSS_HOME/standalone/data/ directory.
You're welcome to open an issue, for a discussion around it at least. I'm not sure how I feel about adding a goal for it, but here isn't the place to discuss that :)

TOMCAT 7 not deploying war

I have developed a Dynamic Java Project with Eclipse which involves web services(RESTful). After completion I tried to run my project Tomcat 7 runtime of Eclipse IDE, it works fine. I am able to access all my web services.
But, when I created a WAR file out of my project by right-clicking on project and exporting it to WAR file and placed .war file in Tomcat 7's webapps folder. Started the tomcat by running startup.bat, it throws below exceptions and I am not able t access any web service:
I have placed all the required jar files in lib folder of Tomcat.
Exception fixing docBase for context [/Books] (Books is my war file name)
Failed to create work directory [{CATALINA_HOME}\work\Catalina\localhost\Books]
Failed to create destination directory to copy resources.
Could anyone please let me know what I am missing??
Thanks in advance.
Regards,
Piyush
The failed to create "work directory" error can occur if the work folder does not exist in the tomcat7 folder.
Also this error can be caused by tomcat not having sufficient permissions to read, write and execute in the tomcat7 directory.
The issue is because, tomcat is not finding your web.xml location in the classpath.
Do below steps:
Right click on web project-->Properties-->Deployment Assembly--> Add your classpath to web.xml(src/main/webapp) in my case.

Xuggler with Tomcat on Windows 7

I have been developing a web application , here I need to generate thumbnails of videos when they are uploaded by users. I am using Tomcat as my server. So my Tomcat resides in C:\Apache Tomcat 6 . So do i need to include the jar files of Xuggler in C:\Apache Tomcat 6\lib folder ???? and if so which specific jar files do i need to place there ?? which version of Xuggler would be better ? I am not using Maven or Ivy or any dependencies. I am just doing the Web Application in simple Servlet and Jsp concept.
I will explain how to setup xuggler on localhost tomcat 7
download xuggler jars and all its dependencies.
then extract the .dll files from xuggler.jar(xuggler5.2.jar or xuggler5.4.jar),it is the binary file which is written i c language.
copy the .dll files,which is perfect for your system (32bit x86 ,64bit x64) to any folder. for example
c:\xuggler.dll
Add the path of .dll to the classpath.
if you are using eclipse in the build path add path of .dll to the native library path to avoid any issues.
This could definitely work ,i have done this lot of times!!!
please vote if you find my answer useful !!!

No Output in the log file generated by logback [duplicate]
