Static calls within Servlets

This is my first post here so apologies if i'm raising questions previously raised.
I'm making major changes to my system, predominantly trying to get rid of the hacks i've added over the years.. however I have a question with regards to best practice with regards to using helper classes.
My application is written as a collection of servlets.
I have a helper class which contains generic business logic used throughout my application.
This helper class consists of a collection of static functions however the class itself is not static.
I call these functions within my servlets using the call
HelperClass.functionname(...)
Now would it better if I created an instance of this class ie.)
HelperClass.getInstance().getFunction(...)
Also should the getInstance() function return the HelperClass as a singleton.
...and/or should the HelperClass itself be static.
Any help/advice on best practices would be greatly appreciated.
Many Thanks.

Some people prefer singletons over static methods for ideological reasons that I don't quite understand. There is one advantage to the singleton method, though: if the data encapsulated by the helper class changes while the server is running, you can have something executed that replaces the original singleton class member (which had the old data) by a new singleton class member (with the new data). This may or may not apply to your class.
And you can't declare a top-level class static.

Problem with servlet call within servlet

I have already a servlet that generates a jpeg images that works fine.
a second servlet generates an pdf document via the iText library and works also fine.
the problem or question is how to call the first servlet to insert an

Have a look to HttpURLConnection object (in java.net package). A example of the code :
URL url = "http://myServer/myJpegServlet";
HttpURLConnection uc = (HttpURLConnection) url.openConnection();
uc.setDoInput(true);
uc.setUseCaches(false);
uc.setAllowUserInteraction(false);
InputStream dataIn = uc.getInputStream();
byte[] buf = new byte[512];
while( (dataIn.read(buf)) != -1 ) {
//Do what you want with the data
datain.close();
uc.close;
Hope this helps!

Calling a Servlet from a JSP within Portal Portlet

We've created a JSP that calls a Servlet when the form is submitted. The servlet handles the request, does some basic processing and then forwards back to a JSP. This works fine outside of Portal.
What needs to be done in order for this to work within a portlet in Portal? We can get to the first JSP which is in a portlet, but as soon as we click the submit button (which tries to call the servlet) we get the basic page not found error. We need to click the button, go to the servlet and have the servlet forward back to our portlet.
I know this is not the ideal way of using Portal however...
Any ideas?
Thanks!

I was wondering is there any way I can call a servlet from jsp? There are two scenarios here
1 - if the jsp is currently being executed/evaluated on the server, then you can use <jsp:include> to "call" a servlet, or <jsp:forward> to cancel the jsp and transfer the control to the servlet.
2 - if the page is already loaded and running in the client, then the only way to call a servlet is making a HTTP request as from any other html page. Jave code does not execute on the client, so you have to use html/javascript at that point.
Calling a servlet within another servlet.
lets say one servlet maintains all dynamic html. I call this servlet from another servlet to create a dynamic page and then insert values into it.Close, but the standard pattern is the reverse of that. What normally happens is you retrieve the values to put in the page, and then call the page, passing in those values. Thats why often you get a servlet/actionbean getting called, which then forwards to a JSP to display the result. The servlet/bean loads all the values required into scope, and then the JSP presents the data.

I want to send a response from the servlet and then call another servlet.

Hi,
I want to send a response from the servlet and then call another servlet. can this happen. Here is my scenario.
1. Capture all the information from a form including an Email address and submit it to a servlet.
2. Now send a message to the browser that the request will be processed and mailed.
3. Now execute the request and give a mail to the mentioned Email.
Can this be done in any way even by calling another servlet from within a servlet or any other way.
Can any one Please help me out.
Thanks,

Static calls and performance

Is there anyone with knowledge fo the internal workings of the JVM?
I was wondering, is a static call in Java automatically synchronized? I can't find a resource with a satisfying answer, so I thought I try it here. I was having some performance problems reading from a file, So I decided to read the file once while strating up the application. But it's a web application, so I'm using servlets. You have to be careful not to use synchronized methods within the dopost or doget of a servlet, because all requests will be handled by the same thread initially. But referencing a class using a static method also gave me performance problems. Simply doing a static call for a String for times instead of one time increased the performance of the application by 100%. Does anyone have the theoretical foundation behind this behaviour?
regards,
Jeroen.

static methods are not synchronized unless you use the key word "synchronized". Using "synchronized" with a static function blocks on any other static synchronized methods from a different thread, however it will allow access via a synchronized non-static method. Check out "Taming Java Threads" by allen holub for more info.
if you can read the file in the init() method and cache it then you wouldn't have to read it every time in the dopost(), doget() methods.
I have written a free Java performance monitoring tool called JAMon that should help you track down your performance problem.
It couldn't be easier to use and provides a wealth of information including performance and scalability statistics and more.
Other features include the ability to monitor production code,
and to disable monitoring at runtime.

How to call a servlet from another servlet

hi everybody,
i have a problem, i have to call one servlet from another one.
Everything works on my pc, but when i install the application on the customer's server i got an error about an Uknown URL followed by the name of the machine.
Wjat i do is the folloqing :
String urlString = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+"/"+servletName;
URL url = new URL(urlString);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
the variable servletName is the name of the servlet i have to call.
Is there another way to call the servlet ?
All the servlet are installed in the same server.
Any suggestion ?
Cheers.
Stefano

Sweep is correct about requestDispatcher being another approach for inter-servlet delegation; the only issue that i recall with this approach is that it defaults the method of the destination servlet to the one it was called from...for example, calling servlet2 from within servlet1.post() resulted in the dispatcher attempting to utilize servlet2.post() - i believe that i searched for a parameterize solution to no avail :( (ended up handling the request by placing a "fake" doPost() in servlet2 that simply called servlet2.doGet())
however, if your application is functioning correctly on your pc/webserver then the problem may be external to servlet communication (e.g. client webserver's ports not configured or blocked, missing runtime classes, etc.)
my suggestion would be to set aside the programmatic concerns for the moment - what is the response if you open a browser on a client's machine and access the URL in question (i.e. http://clientserver:port/stefanoServlet)? If it will not respond to access in this manner then it certainly won't when your application calls for it.
It's possible that there is a coding error but, given the info supplied, i'd start examining the environment, first. Let us know if you have any luck with the test i recommended or not (please provide abundant detail). Or, if you've found the solution then you may want to post back with a quick blub so the next person knows how to escape the trap.

How can i call a servlet from a servlet ?

Hello,
Can i call a Servlet from within a Servlet ?
and is it "right thing" to Do ?
Thanks

JMO, but I wouldn't do it like this.
Don't have a remote object like a servlet doing database queries for your app. That will mean TWO network hops for every query if the database resides on another machine. The network is the biggest bottleneck you've got.
Write a JavaBean that does the database stuff for you and just have the first servlet instantiate it when it needs it. A Bean has a better chance of being reused, too. Write a TableGateway or DAO for your object.
Or write an EJB to do it.
The only time I've done a servlet-to-servlet connection like that was for one servlet running in a DMZ that would authenticate a user and then forward the request to another servlet running inside the second firewall.
I wouldn't encapsulate database query logic in a servlet like that. JMO - MOD

Calling a servlet from a servlet?

Is it possible to call one servlet from another servlet?

You should use servlets to process requests. If what you're asking for is to execute a piece of logic within a servlet before its finished processing the request, then you should consider using a regular java class instead of a servlet. If you just want to send the request information to another servlet you can use getRequestDipatcher().forward(..) method. Keep in mind that by doing so you'll interupt the current servlet.

D.

Calling One Servlet From Another

Thanks in advance for any advice!
I would like to call servletB from servletA then use the response returned from servletB within the processing of servletA.
I have checked the forums and jGuru but nothing I've found really matches the problem. RequestDispatcher has "forward" and "include" but I do not want to include the reponse from the called servlet in the response of the original one.
Here is the situation. I have a web application that uses an applet front-end using a mainframe datasource. The applet displays data in various JTables and prints various reports.
The applet calls a servlet(B) with an SQL statement in the request that responds with a Vector of data to be displayed in the JTable. This is working fine.
The applet also calls servlet(A) which uses iText from SourceForge to create a PDF report that is sent back to the browser for display in Adobe Reader. This also works fine.
Because I cannot figure out how to call servletB from within servletA, my current workaround is to embed the code of servletB inside servletA. Not very good OOP and as the application grows maintaining this will become a problem.
Any suggestions would be greatly appreciated.
Max

Why don't you just take the code that the applet uses to "call" servlet B and replicate that code into servlet "A"? (Or better still, create a class to do that, which could be called both from the applet and from servlet A.)

RFC call in Servlet problem

Hello,
I have servlet in my web application module, and I try to make RFC call, within it. I use com.sap.mw.jco.*.
I compile it but when run the server respond with
Application error occurs during processing the request.
Details: java.lang.NoClassDefFoundError: com/sap/mw/jco/JCO The ID of this error is
Exception id: [000C763FB7EE00390000001F000007E800043A148A45F9B4
I think that I should packaged the jco lib in my war and make it available to servlet, but how can I do this ?
Thank for any help.

Hello,
Thanks a lot Maksim, Bhavik, you helped me.
I try to make a reference and now the library ClassNotFound error is gone.
But now I have a next problem with RFC call, I also wrote it to post (Webdynpro VS. Java Servlet). I have a code in which I make RFC call. When I embed this code into regular Java aplication and run, it will return results as I expect. (of course I must run it with jco lib .jar in classpath). But when I run it on my servlet, I got an exception with message: "'mshost' missing"
I don't know what this supposed to mean, because I run the mentioned application, also from PC where I have j2ee engine installed and it work.
If you can please help.
(and thank for your help again (Maksim, Bhavik))

Urgent!!!!!!!!!!Calling a servlet setting cookie

Hi,
     The following is the complete picture of my problem. I am having a simple java servlet program in my domino server. (regarding the set-up's for executing the servlet program in the domino server....all are through...no problem over there...every thing is done, as per the guidence in the domino administration help).
     I want to contact my above said servlet program (in my domino server), from my simple java program (in my client machine). To contact the servlet program from my client machine, i am using the cookie generated by the BROWSER (Internet Explorer), as the entry in to the domino server. But still the servlet program is not getting executed.
     As far As the servlet execution from the browser ("http://192.168.10.12:8001/servlet/testing"), the servlet program is getting executed. But If I get the same cookie (DomAuthSessID) from the browser, using the "alert(javascript:document.cookie)"......and try to call the servlet from my java program, the servlet is not getting executed....could u pl. advice me for the above problem.

Hi Roger
Thank you for your reply.
My original feed is: http://casa-egypt.com/feed/
However, because I modified the feed http://feeds.feedburner.com/imananddinasbroadcast and nothing changed, I redirected it to another feed and then I deleted this feed.
Is there any way to change the feed in itunes? The only feed I have now is http://feeds.feedburner.com/CasaEgyptStation
I tried to restore the feed http://feeds.feedburner.com/imananddinasbroadcast but feedburner refused.
I know that I missed things up but I still have hope in working things out.
Thanks is advance.
Dina
