as you can see alot of forums posts are able to do that. But i been having problem finding a regular expression that will work for all the urls.

Can advise further?

Thanks for input.

Can anyone assist to explain how does this regular expression work exactly?

message = message.replaceAll("(?:https?|http?)://[\\w/%.\\-?&=!#]+(?!.*\\[/)",
"$0");

And also how can i improve it to match the urls.

E.g. like how to make it match url like

http://www.google.com.sg/#hl=en&output=search&sclient=psy-ab&q=test&oq=&aq=&aqi=&aql=&gs_sm=&gs_upl=&gs_l=&psj=1&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&fp=37e992000c3eb140&biw=1366&bih=638

Or url with special characters like !#&'()*+,-./:;=?@[]_~$

Please refer to below regular expression

message = message.replaceAll("(?:https?|http?)://[\\w/%.\\-?&=!#]+(?!.*\\[/)",
"$0");

I also notice that certain links like http://www.google.com.sg/#hl=en&output=search&sclient=psy-ab&q=test&oq=&aq=&aqi=&aql=&gs_sm=&gs_upl=&gs_l=&psj=1&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&fp=37e992000c3eb140&biw=1366&bih=638 is not able to convert to html hyperlink successfully.

Can anyone advise how to improve the regular expression?

Hi,

can anyone advise why i encountered index out of bouns exception when running this method to replace the value by $ sign?

E.g. i pass in a message $$vmdomodm$$

message = message.replaceAll("$", "$");

I encounter this error after deployment of the java web application (.war). If i remove the server.policy file. I will not encounter this error however it means that there will be no security. I realize that the error will occur if i include the following in server.policy which by default is included permission java.lang.RuntimePermission "modifyThreadGroup";

If inside the server.policy file i just remove this permission java.lang.RuntimePermission "modifyThreadGroup";

I will get access denied as by default the security manager will check for this permission

Anyone have any idea what is wrong and how do i resolve this?

java.lang.UnsupportedClassVersionError: Bad version number in .class file


any idea?

Unable to initialize Struts ActionServlet due to an unexpected exception or error thrown, so marking the servlet as unavailable. Most likely, this is due to an incorrect or missing library dependency.

I got the above error..when i try to run a struts application..
