Sir/Mam, Am M.Dhivya, learning about apache lucene [Java]. I have installed JDK-6 update 4 and NetBeans-6.5.1 I downloaded the lucene-1.9-final.zip file and followed the steps given in docs to run the demo. The extracted lucene-1.9-final folder from the downloaded zip file is in D:\ and the lucene-core-1.9-final.jar , lucene-demos-1.9-final.jar and src is in D:\lucene-1.9-final\ As said i have set the classpath in environment variable PATH in System properties as, D:\lucene-1.9-final\lucene-core-1.9-final.jar; D:\lucene-1.9-final\lucene-demos-1.9-final.jar; Then in the command prompt i gave the command, D:\lucene-1.9-final>java org.apache.lucene.demo.IndexFiles d:\lucene-1.9-final\src But got the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/lucene/dem o/IndexFiles Caused by: java.lang.ClassNotFoundException: org.apache.lucene.demo.IndexFiles at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) Am a beginner just started to learn about lucene by my own interest after knowing about its value. But now am scared as the things are totally blind for me. I went in through all the forums but couldnt find the solution. I couldnt find out where am missing or my procedure to run lucene demo is wrong. Kindly let me know a solution for which am struggling for past one week. Thanks in advance M.Dhivya
