Usually it's a problem with an incomplete build of a project, or with use of a modern compiler for that obsolete JVM without using -target and -bootclasspath, not the application class path.

I guess your code is intended to run inside an app server and not as standalone app. Arne >NoClassDefFoundError my condolences. see http://mindprod.com/jgloss/runerrormessages.html#NOCLASSDEFFOUNDERROR SignatureRoedy Green Canadian Mind Products The Java Glossary http://mindprod.com On 23 nov, 05:15, rony.j...@gmail.com wrote: > Hi all, > i am using quartz job scheduling api for my project. when i run a [quoted text clipped - 6 lines] > thanks, > ronan Hi everybody! This could be because you are using the last version of quartz but your jvm is older that 5. I had the same problem and that was the reason! > On 23 nov, 05:15, rony.j...@gmail.com wrote: >> Hi all, [quoted text clipped - 13 lines] > your jvm is older that 5.

If that is true, it would definitely behoove one to upgrade to Java 5, or better yet to the current version, since Java 1.4 will be retired in 2008, and all earlier versions are already past End-of-Life.

This exception always causes a *lot* of confusion. It is *not* the same as ClassNotFouncException: it is not a classpath or JRE version or jar-contents problem. What it means is that the file that was reached via the normal classpath search mechanism didn't contain the expected class, i.e. that the directory the .class file was in didn't correspond to its package declaration. > rony.j...@gmail.com wrote: > > Hi all, [quoted text clipped - 6 lines] > class, i.e. that the directory the .class file was in didn't correspond > to its package declaration.

Make sure all dependencies are in the right place in the environment. Make sure that the deployment JVM version is at least the target version of your app. Make sure that all classes in your project got recompiled. Make sure that classes that get injected at runtime, as is common with a lot of javax classes, actually do get injected at runtime. Sometimes a bad deployment descriptor can ruin your whole day. SignatureLew > In this case, how can I get it right? In *any* case, make sure that the directory the .class file appears in corresponds to its package name, and don't rename or move .class files around after they're compiled. > marze...@gmail.com wrote: > > In this case, how can I get it right? > > In *any* case, make sure that the directory the .class file appears in > corresponds to its package name, and don't rename or move .class files > around after they're compiled. This is confusing and the Quartz documentation doesn't help much. But here's how to get things running: In order to run the Quartz demo applications, you MUST have the Sun Java Transaction API classes (available here: http://java.sun.com/products/jta/) Download the class files and create a JAR file named jta.jar by executing the command: jar cf jta.jar javax Then add the file jta.jar to your eclipse project and add the library to the class path. If you don't do this, you will get the following error when you try to execute a Quartz based application: java.lang.NoClassDefFoundError: javax/transaction/UserTransaction Free MagazinesGet these publications absolutely FREE for up to 12 months.
