JSP/Servlet code for searching for Domain availability

Hi Guys
I am giving a service on my homesite which will search for the domain availability. Users will enter the domain name and the code should check whether the domain is already taken or it is available for registration
Please help me out.

Nah, I don't have one myself. WHOIS can work but only for .org, .net and .com (and a few others here and there.) In that case, all you'd have to do is run the command, and look for the text which says it isn't registered..
trejkaz@carroll:~> whois gnifodgjidfo.com
[whois.crsnic.net]
Whois Server Version 1.3
Domain names in the .com, .net, and .org domains can now be registered
with many different competing registrars. Go to http://www.internic.net
for detailed information.
No match for "GNIFODGJIDFO.COM".
Last update of whois database: Sun, 25 Nov 2001 16:58:31 EST <<<The Registry database contains ONLY .COM, .NET, .ORG, .EDU domains and
Registrars.

Write a servlet or JSP based appn?One or the other? I would think the best application would be a combination of the two.
2) Accept Name, address,Credit card number,# of
disney world tickets(adult),# of Disney world tickets
(child)?Yes, you should probably accept those parameters. They are rather necessary for an only sales transaction...

"cancel ticket"Hey, is this a trick question? There are two number 2s. Is it either or? If so, I would choose the first option rather than the second, because I don't know what the web:xml file is, and it seems like it requires several different pages.

Host for jsp servlet

Hi all, I did an web application using jsp servlet.
For broadcasting which is suitable linux cpanel or windows flesk?
Thanks

BumpIf nobody cared about this the first time, why do you
think it needs to be bumped?1. My original post was on Friday, probably not the best time to get a response. So I bumped it up Sunday night to try for a response Monday morning.
2. Fred visits the forums on Friday, but doesn't have a comment. Bob on the other hand doesn't visit the forum on Friday, but he does on Monday, and he has some advice.
3. Do you give up the first time?

}i really need some assistance at the following areas of code :
where the database results are set to attributes of one bean varabridgment (Type Abridgement) - the declaration and use of this bean.
and where this bean is then added to another bean abridgeresults (Type Results) as a List collection.
i get a null pointer exception when i try to retrieve the List from abridgeresults object of Type Results Bean.
i would really appreciate some assistance in this - i really need to go to sleep now - but cant until i solve this issue. - thanks all in advance.

below is exception outputed to tomcat log file.
it is thrown at the following line of code in the jsp that tries to get the List object :
currently jsp code to retrieve List: <% List myAbridgments = (List) request.getAttribute("results");
for (int i = 0; i < myAbridgments.size(); i++) {
abridgment = (Abridgment) myAbridgments.get(i);
%>
line that gives problem is
(results_jsp.java:95)
//myAbridgments - is variable where i store the List object in jsp scriptlet
for (int i = 0; i < myAbridgments.size(); i++) {
Also, i dont understand why the servlet keeps on forwarding to the results.jsp when i even comment out the line of code to forward request oobject to results.jsp - i recompile copy it over original and restart tomcat - but still i get the null pointer exception in results_jsp - but i'm no longer forwarding anything to this jsp. --- i want to do some out.printline statemets in servelt to see some of the data from the query - but i cant as it just forwrads the request to results.jsp - how can i output the data to look at debug - i dont have a log4j logger setup and dont have IDE to be able to place break points - so wanted to just output stuff to browser to have a look at what was going on - but can't as just forwards request on ?

Passing data from jsp/servlet to a Tuxedo Service thru VIEW

Hi..
We are using Tuxedo10g R3 on AIX 5.3..
We have a Tuxedo Service running which takes values from the VIEW and converts that to upper case.. From the jsp page v r passing values to the VIEW fields which will be accepted by the service..
For testing v checked the service with a tuxedo client and it is working fine..
We have defined a jolt repository file for this service and finished bulkloading and coded the servlet also.. After passing the datas from the jsp, the Tuxedo service is called and it is ended.. but in the service only blank values are passed or the datas are not passed to VIEW fields.. It is not showing any error..
The repository file for this service:
service=NSIMPSRV
export=true
inbuf=VIEW
inview=sample
outbuf=STRING
param=FIRSTSTR
type=string
access=in
param=SECONDSTR
type=string
access=in
param=THIRDSTR
type=string
access=in
param=S-FIRST
type=string
access=out
param=S-SECOND
type=string
access=out
param=S-THIRD
type=string
access=out
and the servlet code for this service:
Result result1;
ServletSessionPool servletsession = (ServletSessionPool) joltsession.getSessionPool("demojoltpool");
ServletDataSet joltdataset = new ServletDataSet();
joltdataset.setValue("FIRSTSTR","Testing");
joltdataset.setValue("SECONDSTR","Tuxedo");
joltdataset.setValue("THIRDSTR","Views");
result1 = servletsession.call("NSIMPSRV", joltdataset, null);
System.out.println("FIRSTSTR:"+result1.getValue("S-FIRST",""));
System.out.println("SECONDSTR:"+result1.getValue("S-SECOND",""));
System.out.println("THIRDSTR:"+result1.getValue("S-THIRD",""));
we are not sure why the datas have not been passed.. do anyone have any idea regarding this??
Thanks..

Different Classloader for JSP, Servlets?

Hi!
          Does the WL5-JSP-servlet use an other classloader then the other
          servlets??
          I've previous posted an article with the subject "JSP - Servlet - Static
          Code in Classes".
          I will try to describe my problem better:
          At server startup I pass information to my startup servlet, for example
          the user and pw for our connection pool. The startup servlet instanciates
          the class Global which creates a db-pool with the user and pw getting
          from
          the startup-servlet.
          startup-servlet {
          public void init(ServletConfig config)
          Global.init("user","pw");
          The class Global looks like this:
          class Global {
          static {
          // register jdbc driver
          // store file informations
          static public init(string, string) {
          // init the connection pool with user and pw
          static public getConnection() {
          // returns connection from pool
          All our other servlets then just use the methode Global.getConnection()
          and other methods from the class Global.
          All servlets works perfect and can access the db-pool.
          When a jsp-file is called which also uses the methode
          Global.getConnection(), a new Instance of the class Global will be made.
          In order to init all values again, I would have to call the
          Global.init(user, pw) methode again.
          So my question is: Why does the jsp file causes a new instance of the
          class Global?
          Does the WL5-JSP-servlet use an other classloader then the other
          servlets??


I am seeing the problem is sp3. I can't use sp4 becuase form based
          authentication, FBA, was broken. I can only hope that FBA will be
          re-fixed in sp5.

Weblogic 6.0 (SP2) generates incorrect java code for JSP with response.sendRedirect()

 Hi,
 Here are the steps to reproduce the problem with the examplesWebApp application
 bundled with wlserver6.0(sp2):
 Product: Weblogic server 6.0 (sp2)
 Browser: IE 5.0
 1. Add index.jsp as the welcome file in WEB-INF/web.xml
 2. Create index.jsp as below:
 <%
 response.sendRedirect("index.html");
 return;
 %>
 <html>
 <head>
 <title>Index JSP file</title>
 </head>
 <body>
 This is index.jsp file 
 </body>
 </html>
 3. Create index.html as below:
 <html>
 <head>
 <title>Index HTML file</title>
 </head>
 <body>
 This is index.html file 
 </body>
 </html>
 4. Run the examples server and make sure examplesWebApp is deployed on the examples
 server using the console
 5. Access the URL http://localhost:7001/examplesWebApp
 The page will display a compilation error as below:
 C:\bea\wlserver6.0\config\examples\applications\examplesWebApp\WEB-INF\_tmp_war_examplesServer_examplesServer_examplesWebApp\jsp_servlet\_index.java:89:
 unreachable statement
 out.print("\r\n<html>\r\n<head>\r\n<title>Simple html</title>\r\n</head>\r\n<body>\r\nThis is index.jsp page\r\n</body>\r\n</html>\r\n");
 ^
 and a look at the generated java code for index.jsp (_index.java) will reveal
 the erroneous code snippet below in the jsp service method:
 try { // error page try block
 //[ /index.jsp; Line: 1]
 response.sendRedirect("index.html"); //[ /index.jsp; Line: 2]
 return; //[ /index.jsp; Line: 3]
 out.print("\r\n<html>\r\n<head>\r\n<title>Simple html</title>\r\n</head>\r\n<body>\r\nThis is index.jsp page\r\n</body>\r\n</html>\r\n");
 } catch (Exception __ee) {
 while (out != null && out != _originalOut) out = pageContext.popBody();
 pageContext.handlePageException(__ee);
 The above web application works fine in Tomcat 3.2.X environment. The Weblogic
 server 6.0 servlet engine should not generate the "out.println()" corresponding
 to the html section of index.jsp. The moment it sees the "return", it should stop
 processing further.
 Can someone from Weblogic support team please verify this and let me know when
 this bug will be fixed?
 One interesting thing I noticed was when we last tried weblogic 6.0 at its beta
 stage, it worked fine after we put in a special patch jar file called "redirectfix.jar"
 we received from weblogic team but somehow it got re-introduced by the time it
 was released!!
 We are planning to migrate our product from tomcat 3.2.x to weblogic 6.0. Our
 product has a lot of pages with such conditional {response.sendRdirect("page.jsp");return;}
 blocks. We would really appreciate a faster response form weblogic team.
 Thanks in advance.

Why should it stop when it sees a return? Is that in the spec?

How to get creator codes for search?

How do you figure out/use the creator codes for seaching a file? In the good old OS days (i.e Mac OS) you dragged a file of the kind you were looking for into the search box after selecting "Creator is __". It doesn't work with OS X.
I'm trying to find a Word document that I know was created in a 3 month window. Using Search for those dates and file type "document" has so far turned up over 8000 files, won't stop, and looks like it's returning almost exclusively files with long numbers ending in .cache, for example 123456789-0123456789.cache
ARgh!

Marlinespike
Sorry, I didn't realise that Find wouldn't get extensions that weren't visible!
How did you find "MSWD" was the code?I don't remember, I've known this for years! There are shareware databases available with lists of hundreds of codes. There are also shareware applications that will tell you the creator code and file type – but if you have the Developer Tools installed, you have a free application to do this, but it must be invoked from the command line:
GetFileInfo BS030218.doc
file: "/Users/michaelc/Documents/Correspondence/BS030218.doc"
type: "W8BN"
creator: "MSWD"
attributes: avbstclinmedz
created: 02/18/2003 19:27:31
modified: 02/18/2003 19:27:31The full path to the application is /Developer/Tools/GetFileInfo, but you shouldn't need to type all that since installing the tools modifies your $PATH to include "/Developer/Tools/". So all you need do is type GetFileInfo, then a space, and then drag your file into the Terminal window and press return.

Now after browsing a jpg image file from client side and pressing submit button ;
I am unable display the image in the Upload.jsp file.Though I use
<img src="UploadedPicture.jsp">image</img> HTML code in Upload.jsp
file .
Now I am unable to find out the mistakes which is needed for displaying the picture in the Upload.jsp page..
If any one can help with the proper jsp code to retrive and display the image ,please please help me !!!!!!!!!!!!!!!!!!!!!!!!!!

2) I'm looking at how you called stuff, and you're trying to call the jsp file as an image? That jsp isn't the source of the image, just a page linking to an image. I think if you really want to do things that way you're going to need to just include that jsp within the jsp you're calling it from (or you can do it the easy way, and if you have the information to get the path of the image you want, you could simply call the image from the first jsp you posted)This is incorrect.
There are two JSPs. The second when called will (if it worked) return the source of an image as stored in the database.even when called with <img src=xx.jsp>??
Yes.
If any of what I say next seems obvious or otherwise negative I apologize, just trying to explain and I don't know what you know vs what you don't.
The link in the src is just a URL not a filetype. So just because it ends with JSP does not mean it has to return HTML. The content type is determined by the browser using the Content-Type header returned by the server in the HTTP response. In this case the header is set to be a jpeg so that's what the browser will attempt to interpret the content part of the response as.
So in fact one is not limited to just HTML or images but whatever content type you would like to return (that the browser can understand anyway). This could be HTML or it could be an image of some type or it could be a PDF or it could be an Excel spreadsheet. All you have to do in the JSP is set the header appropriately and then send content that is actually in that format.
This does not just apply to JSP by the way but all other web programming languages. You can do similar things to produce the same results in PHP, Perl, ASP etc.
The only JSP/Servlet complication is whether or not doing this in a JSP is a "good" idea but I am not an expert enough at that to make a definitive statement. Mostly though JDBC in a JSP is a no-no.

So, the upload time will vary on internet connection. If there is an issue with how fast it is uploaded you can check if prefetching is turned on, but this does not really affect uploading [https://developer.mozilla.org/en-US/docs/Controlling_DNS_prefetching Controlling DNS prefetching]
If you search for solutions, you will see a bunch of tweaks as well that may be helpful to your specific computer. [[Upgrade your graphics drivers to use hardware acceleration and WebGL]] to make sure you are all up to date as well.

What is the best editor to use for JSP/Servlet?

Hello,
What is the best editor to use for JSP/Servlet database development.
I'm looking at Dreamweaver,Java Studio Creator.
I want some thing fairly easy to use that has database helper wizards like dreamweaver.
Thanks for the help.
Frank

Is it better to have a servlet do the database work and call it from JSP?No, it's better to have persistence objects do the database work. Servlets handle HTTP requests, and JSPs are HTML factories that should be pure view.
But there are lots of ways to do things. You just have to understand the tradeoffs when you decide.
I do not want to hammer out code, I want to learn the
best way to do things from experienced developers. Sorry, sounded like you just wanted to churn stuff.
"best way" can be subjective. In one app, "best" might be "delivered fastest". For another, "best" might be "most secure" or "most easily modified" or "best performing" or whatever. You won't get a "best" answer, only different choices. And they aren't always so easy to explain or execute.
I'd recommend that you start by reading about layered applications (3-tier architectures) and MVC separation. Once you've Googled enough about that, look into a framework like Struts or Spring or WebWork. That'll help you figure out where to put each responsibility in your app.
I can use dreamweaver to create web apps, but I hate
the arrays used to define fields. It also seems not
to take advantage of connection pooling.Don't know what you're talking about here, Frank. What do fields have to do with connection pooling?
