how to handle multiple request in the servlet...

if we use thread how to implement in servlet ?

Serlets are already threaded. The application container instantiates the servlet, then uses this instance in a new thread for every use.
This is the reason that you should use (almost) no instance variables in a Servlet, but rather that (almost) everything should be local to the method.

Your servlet should extend from GenericServlet and not HttpServlet to handle ftp requests.

How to handle multiple requests to the same servlet at one time?

Hi,
I am new to Servlets. I have doubt regarding ... Handling multiple requests to a servlet at a time.
If we send a single request to a servlet, as know that group of objects such as servlet, servletContext, servletConfig, request, response and etc are created in the server, And if 1000's of requests are sent to a same servlet at a time, and if server memory capacity is less, then 1000's of objects are created in a server which would be heavy burden to Server. How to handle the application and development in such situation?
Kind regards,
veerendra

Hi veerendra reddy ,
By default any web server can will have a thread pool to handle client req's.
In your point also heavy burden to server you are telling that depends on this.
we can configure this min & max size of this thread pool.
by default it will be 0-1000 for tomcat server.
I am not sure in which file this configuration will be.
But I hope in server.xml or some xml file consists this info.
If You what you can edit accordingly. to overcome your heavy burden to server.
Thanks & Regards

How to instance handler.java into servlet

Hi
I don't have much experience in servlet.
I want to instance a handler.java which connects to database and has all sort of methods into a servlet. But I don't know how to do it as servlet is different from normal java files or jsp .
Can anyone help?
Thanks
M

A servlet is just a normal Java class and you can instanciate Objects in the Servlet like you would in any other Java class. That is import the class, declare the reference and then do a new on the class.
The only caveat is that Servlets are multi-threaded so it is best to not have any class level objects unless they are thread safe.

How to handle more than one submit buttons on servlets

Hi:
anyone know how to handle the multiplet submit button on servlet,
such as next, previous, add and so on.
Thank you

Don't worry about because only the button that is clicked will get submitted. In the servlet you just test for the existance of a parameter:
if (request.getParamter("SubmitButton1") != null) { ..... }
if (request.getParamter("SubmitButton2") != null) { ..... }
Save the following HTML code, open in IE and click on the buttons to see what will get sent to the servlet:
<html><head></head><body>
<form method="GET">
   <input type=text name=text1>
   <input type=submit name="Submit1" value="Me">
   <input type=submit name="Submit2" value="you">
</form>
</body></html>

How do I handle sign in trouble when trying to convert a document?

Hi jeunes781,
Are you having trouble signing in to ExportPDF via the website, or from within Reader? If you're using Reader, make sure that you have the most current version of Reader by choosing Help > Check for Updates in the Reader application.
If the issue occurs when you try signing in via the ExportPDF website, please clear the browser cache and try again.
(And if neither of those work, please write back and let us know what the specific error is, and where it occurs.)

How to Handle SAP SUS XML Acknowledgment

Hi folks,
I have a scenario here where the SAP R/3 system sends a Purchase Order document to SAP SUS through a SAP XI Mapping.
After processing the P.O. document, the SAP SUS system, automatically, returns a Acknowledgment message (ns: http://sap.com/xi/XI/Message/30) to SAP XI.
I need to implement a BPM scenario where SAP XI processes this Acknowledgment message and Logs it into my Monitor System (JDBC Adapter). Actually, the SAP XI needs to send to my Monitor System the status (Success or Fail) of the P.O. processing by SAP SUS.
How can I handle this Acknowledgment message with a BPM Scenario? Is it possible?
Best Regards,
Nascimento

Hi Thiago,
Currently in BPM you can do this with ASYNC-SYNC Bridge design.
You can not dirrectly access the content of the ACK, however the BPM shows different behaviours based on the ACK status. E.g. if the ACK contains a success message the BPM will continue in its normal process, if the ACK contains a permanent error, it will either stop or go through an exception branch (provided such a branch has been defined). Have a look at the documentation: http://help.sap.com/saphelp_nw04/helpdata/en/43/65ce41ae343e2be10000000a1553f6/content.htm It doesnt"t state the above mentioned behaviour in detail but says that you need to define an exception branch.
The trickiest part is always to find out, when you will get a transient vs. as permanent error ack. If you are using ACKs with Proxies refer also to this link http://help.sap.com/saphelp_nw04/helpdata/en/29/345d3b7c32a527e10000000a114084/content.htm and this http://help.sap.com/saphelp_nw04/helpdata/en/f4/8620c6b58c422c960c53f3ed71b432/content.htm
Receiver adapters that run on the Adapter Engine support system acknowledgments if they are requested by the sender. Acknowledgements are triggered when a message is successfully processed by the adapter or if an error occurs while it is being processed. Receiver adapters do not support application acknowledgments. The RNIF and CIDX adapters are exceptions to this rule, since they also support scenario-dependent application acknowledgments. Sender adapters of the Adapter Engine do not request any acknowledgments.
However IDoc adapter is requesting application acks. Therefore you have to disable acks for this scenario using report IDX_NOALE.
Also go through these documents for any further help:

How to handle multiple datasources in a web application?

I have a J2EE Web application with Servlets and Java ServerPages. Beside this I have a in-house developed API for certain services built using Hibernate and Spring with POJO's and some EJB.
There are 8 databases which will be used by the web application. I have heard that multiple datasources with Spring is hard to design around. Considering that I have no choice not to use Spring or Hibernate as the API's are using it.
Anyone have a good design spesification for how to handle multiple datasources. The datasource(database) will be chosen by the user in the web application.

Let me get this straight. You have a web application that uses spring framework and hibernate to access the database. You want the user to be able to select the database that he wants to access using spring and hibernate.
Hopefully you are using the Spring Framework Hibernate DAO. I know you can have more that one spring application context. You can then trying to load a seperate spring application context for each database. Each application context would have it's own configuration files with the connection parameters for each datasource. You could still use JNDi entries in the web.xml for each datasource.
Then you would need a service locater so that when a user selected a datasource he would get the application context for that datasource which he would use for the rest of his session.
I think it is doable. It means a long load time. And you'll need to keep the application contexts as small as possible to conserve resources.

How to handle table selection

In the uix guidelines i found the following example on how to handle table selection:
public static EventResult doSelectionEvent(BajaContext bc, Page page,
PageEvent event)
DataObject tableRows = new PageEventFlattenedDataSet(event, "table1");
int index = SelectionUtils.getSelectedIndex(tableRows);
String name = "Nothing Selected";
// make sure that something was selected:
if (index>=0)
DataObject row = TABLEDATA.getItem(index);
name = row.selectValue(null, "name").toString();
EventResult result = new EventResult(page);
result.setProperty("action", event.getName());
result.setProperty("name", name);
return result;
It is not clear to me what TABLEDATA is.
I read in some other thread that it is a DataObjectList and it represents the 'stored dataObjects'.
I suppose '_TABLE_DATA' is not real code, may i ask for an example with real code to understand what it is?
Thanks.

This code works for me, I hope it is useful.
(NB: i fear you will not read correctly the line
with the getRowAtRangeIndex instruction. It's a problem with the editor).

Any IDE ships with a decent debugger where in you can just execute the code step by step, explore the current variable values and check what exactly is happening. For example Eclipse or IntelliJ. If you don´t use an IDE, then just place some System.out.println() or Logger.debug() statements at strategic locations printing the variables of relevance so that you can track in logs what exactly is happening.
or tell any other way to find is my page is thread safe or not...Just write correct code and narrow the scope of the variables as much as possible. If you for example assigned the user object to a static variable or as a servlet´s instance variable, then exactly the same user object would be used everywhere in the application. That kind of logical things.

How to handle spcial different character in

Hi ,
I am dealing with EDI data and I am taking as input and creating out put as xml
but when I am opening the file in XML spy its gving some error like.
" Your file contains two (2) characters thats should not be present in the file as using the Unicode UTF-8 encoding/
The offending characters are :
ä (0xE4), ® (0xAE)
let me know how to handle.
regards
ram

Hi Ram,
the question is how do you exactly create the file and what is your type of the system (Unicode or Non-Unicode) in which you created it ?
The content of the file is Non-Unicode (ISO-8859-1):
E4 = U+00E4 : LATIN SMALL LETTER A WITH DIAERESIS
AE = U+00AE : REGISTERED SIGN
However XML expects UTF-8 by default and there the special characters are encoded differently.
