Use subversion with both eclipse and cli

If you use both eclipse client and cli client, you need to choose the eclipse svn connector version according to your command line client otherwise ,in the acse that your cli client is older than your eclipse svn connector, you can have an error like this : “svn: This client is too old to work with working copy” or if your svn connector is older than your subversion cli client some option could not be present like share project by using the project svn setting´╗┐.

Write xml file with indentation

November 12, 2009 Leave a comment

We are going to see how can transform an org.w3c.dom.Document object in an xml file.

public void writeXmlFile(Document doc, String filename)
			throws TransformerFactoryConfigurationError, TransformerException {
		Source source = new DOMSource(doc);
		// prepare output
		File xmlFile = new File( filename);
		Result result = new StreamResult(xmlFile);

		// write file
		Transformer transform = TransformerFactory.newInstance()
                //indent the xml content
		transform.setOutputProperty(OutputKeys.INDENT, "yes");
		transform.transform(source, result);

The indentation is done with this line by setting to yes the property “OutputKeys.INDENT”

//indent the xml content
transform.setOutputProperty(OutputKeys.INDENT, "yes");

Create axis2 client with ws-security

You need to download the rampart module.

public class HelloworldClient {

     * directory named "modules" which contains rampart

        if (args == null | args.length == 0) {
            System.err.println("Missing arguments");
        clientAxis2Path = args[0];
        user = args[1];

        String action = "";

        HelloworldClient client = new HelloworldClient(clientAxis2Path);
        SOAPEnvelope result;

        System.out.println("UnSecure WS call...");
        result = client.callSayHello(false, user, action);
        if (result == null) {
            System.out.println("\n" + "SUCCESS !!!");
        } else {
            System.out.println("ERROR : An error was expected");

        System.out.println("Secure WS call...");
        result = client.callSayHello(true, user, action);

            System.out.println("RESPONSE " + "\n" + result.toString());
