Problem to retrieve a document within a java class

[Pasche]

I´m running Xindice 1.1b4 on Tomcat 4.1.24. If I try to retrieve a document via console, I have no problems. Now I tried to search for a document within a java class:   import org.xmldb.api.base.*; import org.xmldb.api.modules.*; import org.xmldb.api.*;   public class Read {    public static void main(String[] args) throws Exception {       Collection col = null;       try {          String driver = "org.apache.xindice.client.xmldb.DatabaseImpl";          Class c = Class.forName(driver);            Database database = (Database) c.newInstance();          DatabaseManager.registerDatabase(database);            col = DatabaseManager.getCollection("xmldb:xindice://localhost:8080/db/test");            String xpath = "/output/ART/A0/SSTW";          XPathQueryService service =             (XPathQueryService) col.getService("XPathQueryService", "1.0");          ResourceSet resultSet = service.query(xpath);          ResourceIterator results = resultSet.getIterator();          while (results.hasMoreResources()) {             Resource res = results.nextResource();             System.out.println((String) res.getContent());          }       }       catch (XMLDBException e) {          System.err.println("XML:DB Exception occurred " + e.errorCode);       }       finally {          if (col != null) {             col.close();          }       }    } }   If I try to run this program, I get the following errors and have no idea where it comes from.   java.lang.ClassNotFoundException: org.apache.xindice.client.xmldb.DatabaseImpl       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)       at java.lang.Class.forName0(Native Method)       at java.lang.Class.forName(Unknown Source)       at main.Read.main(Read.java:24) Exception in thread "main"
