Eric - Sounds like you might need to set the CLASSPATH environment variable to include the com.sleepycat.dbxml.* libraries. That would be either a directory of class files or a .jar file. Make sure that the sleepycat stuff is in your classpath then try compiling it again with: javac tool.java -Peter -----Original Message----- From: Eric Lease Morgan <[log in to unmask]> Sent: Jul 5, 2004 12:16 PM To: [log in to unmask] Subject: [CODE4LIB] compiling a BerkeleyDBXML Java program Can y'all help me compile a BerkeleyDBXML Java program? I have compiled and installed BerkeleyDB (version 4.2) and BerkeleyDBXML (version 1.2) on my Linux host with the Java (version 1.4.2-rc1), I think. I know nothing about Java. I found a simple Java program that should allow me to to add, update, delete, get, and query XML files using the BerkeleyDBXML libraries (see http://www.linux-mag.com/2004-02/berkeley_01.html), below: import java.io.*; import com.sleepycat.dbxml.*; public class Tool { XmlContainer db = null; public static void main(String[] args) throws Exception { String database = args[0]; String action = args[1]; String param = args[2]; Database db = new Database(database); if (action.equalsIgnoreCase("add")) { int id = db.insertDocument(readFile(param)); System.out.println("Inserted document " + param + " as id: " + id); } else if (action.equalsIgnoreCase("delete")) { int key = Integer.parseInt(param); db.deleteDocument(key); System.out.println("Document id " + key + " deleted."); } else if (action.equalsIgnoreCase("get")) { int key = Integer.parseInt(param); XmlDocument document = db.getDocument(key); System.out.println(document.getContentAsString()); } else if (action.equalsIgnoreCase("update")) { int key = Integer.parseInt(param); String newContent = readFile(args[3]); db.updateDocument(key, newContent); System.out.println("Document id " + key + " updated."); } else if (action.equalsIgnoreCase("query")) { String result = db.xpathQueryAsString(param); System.out.println(result); } db.close(); } public static String readFile(String param) throws Exception { BufferedReader in = new BufferedReader(new FileReader(param)); StringBuffer buffer = new StringBuffer(); String line; while ((line = in.readLine()) != null) { buffer.append(line); } in.close(); return buffer.toString(); } } I try to compile this code with the following command: javac Tool.java But it returns the following error: Tool.java:11: cannot resolve symbol symbol : class Database location: class Tool Database db = new Database(database); ^ Tool.java:11: cannot resolve symbol symbol : class Database location: class Tool Database db = new Database(database); What do I need to do (with line #11) in order to make a Tool.jar file? Does the error mean that "Database" is not a valid function call in the BerkeleyDBXML libraries? -- Eric "Clueless" Morgan
