Answer 1

You should encode the MSG string before creating a URL from it.

String encodedMSG = URLEncoder.encode(MSG, "UTF-8")
String url="http://192.168.2.144:8080/SDAX/homePage.do?actionFlag=edistrict&&MSG="+ encodedMSG;

Edit

There won't be any problem in retrieving the data after encoding. If you have programmed this servlet homePage.do then you should use URLDecoder.decode() method in it.

1. Since vertical bar(|) is not a valid URI character thats why You are getting URISyntaxException. Solution: As suggested by kaysush, you need to encode/decode your url. For more on this, Please check folowing url: Cannot process url with vertical/pipe bar
2. You havn't explained what you are trying to achieve here. I hope it isn't by mistake. but As per you question, You are trying to post a url and In your code you are using HttpGet(url);
