You cannot do it exactly. Taking any image and resizing to a smaller size will always lose some detail or definition. If your picture does not size clearly then you will have to find another picture.

Your message is not very clear, please try and explain what is not working. I would also suggest you move this to the Web Development[^] forum, as your question appears to be concerned with Web issues rather than Java.

It depends a bit on how the page was called, but for as far as I know you can't get the complete URL simply by one call. You will need to construct it yourself as follows:

String url = request.getScheme() + "://" +
             request.getServerName() + "/" +
             request.getContextPath() + "/" +
             request.getServletPath() +
             (request.getQueryString() != null ? "?" + request.getQueryString() : "");

I haven't done a code check but this should work presuming you are in the servlet or JSP file and have the HttpServletRequest object available as 'request'. Which should be the default for JSP files and the .get() and .post() members in any servlet.

http://wwww.eshop.com/ShowMember?name=Peter White&id=123 : display a JSP page on browser which is called by ShowMember Serlet
But the follwing code will return http://wwww.eshop.com/ShowMember.jsp?name=Peter White&id=123
String url = request.getScheme() + "://" +
request.getServerName() + "/" +
request.getContextPath() + "/" +
request.getServletPath() +
(request.getQueryString() != null ? "?" + request.getQueryString() : "");
I want to get the Serlet which called the JSP page which mean the address does not contain ".jsp"

You could replace the getContextPath() and getServletPath() with getRequestURL() this should provide the url part after the domain up to the query string.

I want to get the Serlet which called this JSP Page

How do you forward the call from the Servlet to the JSP, are you doing this with the RequestDispatcher.forward() or by a response.sendRedirect()?

If you are using the sendRedirect it is impossible to get the path of the servlet, as this is lost by a secondary client call to the JSP page.

Executable jar Not Running on Mac OS.

17-May-10 20:53

Hello Friends
I am creating a Executable jar file and it is loading file in Windows but If I use same Execuatble jar file on MAC os then it is not loading the file.

But If I open Viewer thru batch file in which I am setting the Heap space then it is loading the file.(In mac ,we cant run batch,I just copy paste into console).

So,to open a file in MAC do i need to do some other settings for heap Space.

Thanks & Regards

Hi I know that I am disturbing a lot with my forums.I am so sorry if my questions are irritating u but I have no other option to post here,as Now I will not say I am new to java but now i learned a lot but still to learn more.

Hi Yogesh,
There is no problem with your questions, after all, this is the reason these forums were created. However, as I mentioned in one of your previous threads, there may not always be someone reading the messages who knows the answer. This question, for example, is specific to MAC OS but I think most of the people who read this forum are Windows/UNIX/Linux specialists so you may not get a quick solution.

Hello
Thx for ur reply but I think u misunderstood my question.I dont want to run my jar file thru any scripting language as it is Executable jar file.So It should run by clicking itself and its happening on other operating system except Mac OS.
But when i tried to run my executable jar file by clicking itself,it opens the application but not loading the file.

And when i run my application thru some scripting it opens and loading the file too.
In my scripting I am setting some heap size.

But I want to run thru by clicking itself only.
So,Is any way to do ?

Thanks & Regards
Yogesh

How to set java path in coding

17-May-10 21:48

Firstly this is the Java forum. Secondly it is impossible to guess what your program is doing without the source. I suggest you go to the person that supplied the program and ask them for help.

Hello Friends
I created a jar file and I tried to run on Windows7 thru batch file in which I m giving the path of java like this

set path=%path%;c:\Program Files (x86)\java\bin

to find the java from 32bit.

Now I installed 64bit Java and it is under ProgramFiles inspite of ProgramFiles(x86).

If i give tht path in batch file it would run but I dont want to use batch file.I want to run application directly thru jar file and I want tht it found s the automatically the java path first from ProgramFiles and if doesnt found there then look in ProgrmFile(x86)?

Is any soultion?
or is it possible thru Enviorement variable?I really need some help.
Thanks

Check your default PATH environment variable and make sure it contains entries in the form:

c:\Program Files\java\bin;c:\Program Files (x86)\java\bin; ...

In this way it will search c:\Program Files\java\bin first, if it exists.
