Meanwhile, am using lucene 3.6.2 version. The problem is jvm instantiation from any python code using lucene caused as a result of the classes I added to lucene core.
---------- Forwarded message ---------- From: Alexander Alex <greatalexander4r...@gmail.com> Date: Fri, Oct 17, 2014 at 12:31 PM Subject: Pylucene jvm CharArraySet Error To: pylucene-dev@lucene.apache.org I added a customized lucene analyzer class to lucene core in Pylucene. This class is google guava as a dependency because of the array handling function available in com.google.common.collect.Iterables in guava. When I tried to index using this analyzer, I got the following error: Traceback (most recent call last): File "C:\IndexFiles.py", line 78, in lucene.initVM() JavaError: java.lang.NoClassDefFoundError: org/apache/lucene/analysis/CharArraySet Java stacktrace: java.lang.NoClassDefFoundError: org/apache/lucene/analysis/CharArraySet Caused by: java.lang.ClassNotFoundException: org.apache.lucene.analysis.CharArraySet at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) Even the example indexing code in Lucene in Action that I tried earlier and worked, when I retried it after adding this class is returning the same error above. Am not too familiar with CharArraySet class as I can see the problem is from it. How do i handle this? Attached is the java files whose class were added to lucene core in pylucene. Thanks
