Tigase服务端集成问题总结

eclipse jdk8中导入JPEGImageEncoder报错：
java.lang.ClassNotFoundException: com.sun.image.codec.jpeg.JPEGCodec

//import com.sun.image.codec.jpeg.JPEGCodec;
//import com.sun.image.codec.jpeg.JPEGImageEncoder;
private static void writeFile(Image image, int width, int height, String thumbnailFile) throws Exception {
		if (image == null)
			return;
		BufferedImage tag = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
		tag.getGraphics().drawImage(image, 0, 0, width, height, null);
		FileOutputStream out = null;
		try {
			out = new FileOutputStream(thumbnailFile);
			ImageIO.write(tag, JPEG, new File(thumbnailFile));
//			JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
//			encoder.encode(tag);
		} catch (Exception e) {
			e.printStackTrace();
			throw new Exception(e);
		} finally {
			if (out != null) {
				out.close();
			}
		}

	}

JPEGImageEncoder在jdk1.7之后已经废弃，此类在eclipse自带的jdk中可以找到，下面说解决方案。
jdk1.7后，使用ImageIo代替此类。

public static void saveImage(BufferedImage dstImage, String dstName) throws IOException {  
    String formatName = dstName.substring(dstName.lastIndexOf(".") + 1);  
    //FileOutputStream out = new FileOutputStream(dstName);  
    //JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);  
    //encoder.encode(dstImage);  
    ImageIO.write(dstImage, /*"GIF"*/ formatName /* format desired */ , new File(dstName) /* target */ );  
}  

参考
程序包com.sun.image.codec.jpeg不存在
java.lang.ClassNotFoundException: com.sun.image.codec.jpeg.JPEGCodec

smack4.1.6连接tigase7.1.0时报错，下面这个问题是缺少jar包引起的(确认账号密码正确的前提下)，导入smack-sasl-provided-4.1.6.jar 包即可 jar包下载地址

tigase服务端修改消息路由的域名，
即本来是发送给 80001@192.168.10.120的消息，在服务端将其修改为发送给80001@192.168.10.130
修改tigase.xmpp.XMPPDomBuilderHandler.java

private Element newElement( String name, String cdata, StringBuilder[] attnames,
															StringBuilder[] attvals ) {
		++elements_number_limit_count;
		
		System.out.println("newElement: name="+name+" cdata="+cdata);
		if (attnames != null) {
			for (int i = 0; i < attnames.length; ++i) {
				// Exit the loop as soon as we reach end of attributes set
				if (attnames[i] == null) {
					System.out.println("newElement attnames["+i+"] is null");
					continue;
				}else {
					System.out.println("newElement: attnames["+i+"]="+attnames[i]);
					if(name != null && name.equals(Message.ELEM_NAME)) {
						System.out.println("newElement: attnames[i]="+attnames[i]);

init.properties读取过程
系统启动过程中，tigase.conf.ConfiguratorAbstract.java parseArgs方法会读取init.properties配置文件，然后将配置文件中的配置以map格式存储到系统内容中
获取时以System.getProperty(key)方式来获取 配置中的内容
