How to run java behind proxychains

I have a java class in which htmlunit's webclient gets html pages. I want to send the packets through Tor proxy. When I set the proxy in my java code, by setting System properties:

System.getproperty("socksProxyHost","127.0.0.1");
System.getproperty("socksProxyPort","9050");

, it works correctly. But when I want to use tool ProxyChains,

proxychains java -jar MyPackagedJava.jar

, it is not work! In the other words, I want to send htmlunit's packets through ProxyChains. How to do it?

Java doesn't send the packets via proxychains' proxies. So, you have to set the proxy in your coding. For example when using HtmlUnit & WebClient object to request a web page, just use the followings:

**WebClient webclient;**
if (proxy != null && !proxy.getHost().trim().equalsIgnoreCase("")) {
        if (proxy.getType() == null || proxy.getType().trim().equalsIgnoreCase("")
                || proxy.getType().trim().equalsIgnoreCase("http") ||
                proxy.getType().trim().equalsIgnoreCase("https"))
            webclient = new WebClient(BrowserVersion.CHROME, proxy.getHost(), proxy.getPort());
        else if (proxy.getType().trim().equalsIgnoreCase("socks")) {
            System.setProperty("socksProxyHost", proxy.getHost());
            System.setProperty("socksProxyPort", String.valueOf(proxy.getPort()));
            webclient = new WebClient(BrowserVersion.CHROME);
        }
        webclient.getCredentialsProvider().setCredentials(AuthScope.ANY, new NTCredentials(
                proxy.getUsername(), proxy.getPassword(), "", ""));

    } else {
        webclient = new WebClient(BrowserVersion.CHROME);
    }

The object proxy is an instance of Proxy class defined below:

public class Proxy {
    private String host, username, password,type;
    private int port;


public String getType() {
    return type;
}

public void setType(String type) {
    this.type = type;
}

public Proxy(String host, int port, String username, String password) {
    this.host = host;
    this.port = port;
    this.username = username;
    this.password = password;
}

public void setHost(String host) {
    this.host = host;
}

public String getHost() {
    return this.host;
}

public void setUsername(String username) {
    this.username = username;
}

public String getUsername() {
    return this.username;
}

public void setPassword(String password) {
    this.password = password;
}

public String getPassword() {
    return this.password;
}

public void setPort(int port) {
    this.port = port;
}

public int getPort() {
    return this.port;
}

}

HtmlUnit does not use the java proxy settings, you have to configure this during your client setup. Have a look at HtmlUnit -Getting started; there is a sample for proxy setup.
