Hi Jukka,

Here's a complete code sample I'd use:

   File file = new File("document.pdf");

   Metadata metadata = new Metadata();
   metadata.set(Metadata.RESOURCE_NAME_KEY, file.getName());

   InputStream stream = new FileInputStream(file);
   try {
       String content = new Tika().parseToString(stream, metadata);

       System.out.println("Title: " + metadata.get(Metadata.TITLE));
       System.out.println("Content: " + content);
   } finally {

   }

stream.close(); // note that you need to explicitly close the stream

I'm working on a Macbook with MacOS X 10.6.1 und Maven Version 2.2.1.

Any idea what's wrong?

Thanks for the code sample. When I try to run it, it throws the following Exception: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/ pdfbox/pdmodel/PDDocument at org.apache.tika.parser.CompositeParser.parse(CompositeParser.java: 121) at org.apache.tika.parser.AutoDetectParser.parse (AutoDetectParser.java:108) Caused by: java.lang.ClassNotFoundException: org.apache.pdfbox.pdmodel.PDDocument I tried to install Tika again with Maven, the result is an Exception too (after the Tests for "Building Apache Tika application"): [INFO] ------------------------------------------------------------------------ [INFO] ------------------------------------------------------------------------ [INFO] ------------------------------------------------------------------------ at org.apache.felix.bundleplugin.BundlePlugin.buildOSGiBundle (BundlePlugin.java:391) at org.apache.felix.bundleplugin.BundlePlugin.execute (BundlePlugin.java:282) at org.apache.felix.bundleplugin.BundlePlugin.execute (BundlePlugin.java:236) at org.apache.felix.bundleplugin.BundlePlugin.execute (BundlePlugin.java:227) at org.apache.maven.plugin.DefaultPluginManager.executeMojo (DefaultPluginManager.java:490) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals (DefaultLifecycleExecutor.java:694) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalWithLifecycle (DefaultLifecycleExecutor.java:556) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal (DefaultLifecycleExecutor.java:535) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures (DefaultLifecycleExecutor.java:387) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments (DefaultLifecycleExecutor.java:348) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute (DefaultLifecycleExecutor.java:180) at org.apache.maven.cli.compat.CompatibleMain.main (CompatibleMain.java:60) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) [INFO] ------------------------------------------------------------------------ [INFO] ------------------------------------------------------------------------
