Using regex on fuse esb

[rogelio_sevilla1]

Hello everyone:

I don't know if this is the right place to ask this question but here it goes.

I'm building a camel route which gets an html code and then, it applies a regular expression match to extract certain data.

I know the regex works right when deployed as a simple java app. But i know that fuse ESB is a multi threaded enviroment so, there are more difficulties when using non thread safe code.

To be honest, i'm not a multi-thread advanced coder, so I was wondering if anyone here has some advice on using regex on fuse esb. this is the method i'm using:

    private static final Pattern regex = Pattern.compile("link href='(.*)'");

    public String getUrls(@Body String htmlcode) {

        Matcher matcher =  regex.matcher(htmlcode);

        StringBuffer urls = new StringBuffer("");

        synchronized(this){

        matcher.matches();

        matcher.find();

        while (matcher.find()) {

            urls.append(matcher.group(1));

            urls.append("\n");

        }

        matcher.reset();

}

        return urls.toString();

}

What i want to get in here is a list of urls. Curiously, when i extract the url list, around 8 links from 150 are totally wrong. something like:

http://right_url.com?a=1111

http://right_url.com?a=2222

http://right_url.com?a=3333

htp:/wrong_url.com?a=asdsa

http://right_url.com?a=4444

http://right_url.com?a=5555

h:/wrong_url.com?asdsa

I know my regex is fine because i'm executing this code every 5 minutes using a quartz component, and the next time the match is executed (on the exact same html code), the wrong urls are extracted correctly, and then, some others are now extracted incorrectly :-S .I thought the synchronized block would fix this, but not.

I've been dealing with this problem for a couple of days without  success; does anyone has any experience  on fuse esb regex usage  that could shed some light on this??.

thanks a lot in advance.

Nevermind my mystake. I was using another matcher object on another place of the code. Also, the synchronized block was totally unnecesary :-D
