I implemented an API in Java using Eclipse and exported it in the form of a war file.
It is working fine on the system I developed it on.
This is the web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>Favorite-API</display-name>
<servlet>
<servlet-name>Favorite-API</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>favorite.api</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Favorite-API</servlet-name>
<url-pattern>/rest-videos/*</url-pattern>
</servlet-mapping>
</web-app>
Now I want to deploy the API on another system.
Hence I took the war file and deployed it on the Apache Tomcat server of the other machine, following the steps given here.
But on running the API I am getting the following error:
HTTP Status 500 -

What is going wrong? Any help please.
You might have some dependencies missing in your class path.
java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor
Assume your development tomcat has this class/package but not in the tomcat which you are trying to deploy the war.
class def not found for servlet means something servlet api that is regularly available to tomcat is now missing for some reason. Possibly the jar file in tomcat's lib folder (maybe other jar files in the tomcat lib folder) have become corrupted or removed. Both have happened to me at times, bad virtual machine to work on, failed disk, or a maven based build process that would deploy additional api to the lib folder and delete things in there before copying the new lib files.
Seems you are missing the ObjectWeb ASM artifact in your $TOMCAT_HOME/lib directory.
It sounds like the tomcat use does not have permissions to unpack the WAR file into relevant directories, which means the application itself cannot find required classes.
Ensure that Tomcat can write to the temp, work and webapps folder, and their subdirectories.

I am not sure how much did you really searched for this.
Java document state specific reason behind this error.
http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/AbstractMethodError.html
I think your jar are mismatching... Jar that you are compiling at local and jar used while running the application at some other location in different. This is basic issue for most of such issue. You can verify version of your jars...
I looked few more options, but people talk about different versions of jars... Please have a better look on your jars.. It might help....

What have i done wrong here? I just created a Vaadin project using the new project wizard...I did not even add/edit any code to it.
Check that "com.anyaservices.spinthebottle.App_Main" path points to a valid Java file contains public class which extends Vaadin Application class.
I'm just testing Intellij IDEA in combination with an Tomcat 7 serveron Arch Linux.
I got the standard Tomcat Page when starting Tomcat by
sudo /etc/rc.d/tomcat start
I just used tutorial at http://wiki.jetbrains.net/intellij/Creating_a_simple_Web_application_and_deploying_it_to_Tomcat to configure Intellij.
Just a blank project but running Tomcat and opening localhost:8080 in Webbrowser causes following exception:

I'm have no idea why the java compiler is missing. Java Home is set in Tomcat conf correct to
/opt/java
Can anybody help me?
The error is misleading, it can't find Jasper JSP compiler, not Java compiler.
It is org.apache.jasper.compiler.JDTCompiler, and it can't be loaded from the classpath, meaning that most probably JAR file with it (jasper.jar) did not get there for some reason.
Did you download/unpacked Tomcat from apache, or did you install it from your Linux distribution repo? Distribution packages mangle package structure sometimes...
In my web application I'm trying to use custom error page.
However this does not work with Weld. When I navigate to a non-existing page in my app instead of getting custom error page I see exception from Weld:

however it has been fixed in v.7.0.9

I'm using Tomcat 7.0.19, JSF 2.0 and Weld 1.1.2.
Any ideas what happens?
In context of weld only weld-servlet.jar is present in classpath, nothing more
I currently have a class, Reporter.java, which uses JasperReports to generate an HTML report. I have a simple Test.java that calls Reporter.report() and the HTML file is properly generated at a specified file location (I currently have it set as a C:/ path that points into my Tomcat project). Now, I run a Tomcat server with an HTML page that calls generateStatus.jsp which calls Reporter.report() and an exception is thrown.

The line it errors at is
JasperReport jasperReport = JasperCompileManager.compileReport(jasper.getString(Constants.JRXML));
Any suggestions?
Thanks for your time!
Looks like you are missing the Jasper Jar file in the WEB-INF/lib dir of your web-app.
This was a good example to follow:
http://codebackup.wordpress.com/2008/02/29/howto-jasperreports-framework-deployment-to-tomcat/
But I am still looking into generating a "dump" of reports in a directory rather than displaying a report on a single HTML page.
