I want to write an application to call the servlet........

I want to write an application to call the servlet.
the application should perform like a html file , in which the html will submit a form with enctype="multipart/form-data"
and the "post action" will submit the file to the servlet.
I can write an application to communicate with the servlet, but I don't know how to solve the problem with the multipart file submission.
So, what should I do? Any example code?
Thank you very much.

Check out O'Reilly's servlets.com site at
http://www.servlets.com/cos/index.html
It has an example that encapsulates the multipart upload.

Is there any way to call the servlet from the applet

hi all,
My problem is that i have a applet .After the applet completes execution a servlet should be invoked.Is it possible to do so.
I also want to pass a string array to the servlet.
Is it possible to pass a string array to aservlet.
If yes please do inform me that method.
And from that servlet we should be able to redirect the the response of the applet to the servlet or JSP.
The flow is some what lILE THIS

Use windows, want MAC, write openGL applications

Hello,
Apparently I am still a fool in using a MAC and i don't have a
clue about using it but i want to buy such a thing.
2 Problems:
I am a hobby programmer of OpenGL and want to know wether programming MAC application is like (with "like" i don't mean "exactly like" of coure) Win32 API. Ok, All I want is creating
OpenGL applications on MAC. Is this a big problem for a young guy like me?
Next:
I am using much Win32 Apps like Milkshape3D (for OpenGLprogramming). Are there similar Apps on Mac which effect exactly the same or are there Win32 emulatoren on which WinApps can be ran on Mac.
I know i am a fool, please don't mention it in your answers again
Thx for all!

Hi,
Writing OpneGL programs on the mac will be no problem for a young guy like you. Hillegass's book has an example OpenGL/Objective-C program in it. There are quite a few examples on the Apple ADC example code pages too (it's worth joining ADC - there is a free membership option which is good enough for hobbyists like me). I'd recommend learning Objective-C to program OpenGL stuff - nothing beats Objective-C in my opinion (it might even wean you off OpenGL - have a look at quartz 2d and core image). You'll be using Xcode as the IDE - it's good, powerful and easy to use.
As I don't use a pc I can't say anything about your second question except dump the pc, it's holding you back...

Getting Application Name of the Servlet

Hello Developers,
I need to retrieve the Application Name of my Servlet to display it in my web page.
I try to use the ServletContextName but i'm not able to implement it (I think that my version of the Servlet API is too old).
Thanks for your help.
Hyppo250

// this = your servlet
this.getServletName()this will return the servlet name defined in the web.xml configuration file
e.g.:
<web-app>
    <servlet>
        <servlet-name>THIS_IS_THE_NAME_YOU_WILL_GET_BY_USING_getServletName()</servlet-name>
        <servlet-class>...</servlet-class>
    </servlet>
</web-app>

How do you get the web application path from the servlet?

I have created a web application which is installed in
/webapps/myApplication
/webapps/myApplication/data/users.xml
/webapps/myApplication/WEB-INF/classes/myServlet
How can you get the path to the "users.xml" file from the "myServlet" file?
The code below doen's seem to return the xml file. anybody knows why?
public class myServlet extends HttpServlet {
public void doGet( HttpServletRequest req, HttpServletResponse res ) throws ServletException, IOException
File myXmlFile = new File("/data/users.xml");

Try this..
String FileName = getServletContext().getRealPath("\\data\\users.xml");
File myXmlFile = new File(FileName);
hope this helps..

Write to application log in user exit

Hi all,
I want to write a collection messages to the application log in user exit EBIA0003, user exit for transaction EA00, but I only can write one if I just use
message eYYY(x) with lv_msgv1
                                  lv_msgv2
                                  lv_msgv3
                                  lv_msgv4.
It will be placed in the log after the exit.
I've already tried with the BAL functions, but it doesn't seem to work or maybe I'm doing something wrong. Is there a way to write a collection of messages in to the application log in this user exit?
greetz Pieter

Hi Pieter,
you can do using BAL functions if the lop is already opened. Try to find out what parameters the transaction uses for LOG access (handle!). Do the calls in the exit accordingly.
We append messages to the current log using FUNCTION 'BAL_LOG_MSG_ADD'. If the log handle is not available, you might access it using dynamic assign like
ASSIGN ('(<program>)<field>') TO <field> .

Closing a webdynpro application, should call a portal page

Hi All,
I have a requirement in which, after a webdynpro application is closed in portal, the portal should show the workset content from which the webdynpro application is triggered.
For example,
Wedynpro application Created is ZWDA1.
Two iviews are created in portal which refers to the webdynpro application ZWDA1, the portal Iview names are ZPORTAL_IVIEW1, ZPORTAL_IVIEW2.
Two worksets ZWORKSET1 & ZWORKSET2 are created in portal which refers to Iview ZPORTAL_IVEW1 and ZPORTAL_IVEW2 respectively.
Two roles ZROLE1 & ZROLES2 are created in portal which refers to workset ZWORKSET1 & ZWORKSET2 resepectively. These two roles are assigned to users ZUSER1 and ZUSER2, when these user logs into portal they will see the content of the workset ZWORKSET1 & ZWORKSET2 respectively.
Assuming ZUSER1 and ZUSER2 invokes the portal ivew ZPORTAL_IVEW1 & ZPORTAL_IVEW2, the underlying webdynpro application called is same. So in the webdynpro application only I need to write the code to close the application and call the workset ZWORKSET1 for ZUSER1 and workset ZWORKSET2 FOR ZUSER2. This differentiation I am not able to indentify in webdynpro application, I thought of using relative navigation.
Any suggestion to achieve this functionality is greatly appreciatable

H.K.Hayath Basha.

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.

Passing username and password while calling the simple HTTP API

Hi,
I want to execute a graph by calling the http api from a java code. However, this gives me a 401 unauthorized http error as I am not passing the username and password to the clover http url.
The following is the format of the constructed url. - http://<host>:<port>/clover/simpleHttpApi/graph_run?sandbox=<sandboxname>&graphID=graph/Baseline.grf&verbose=FULL
Can anyone suggest how to pass user credentials to this url.
Thanks

Brett,
Thanks for the response.
The idea is to run the baseline graph using the simple http api and get the run id of the job. Then I plan to call
this url - http://<host>:<port>/clover/simpleHttpApi/graph_status?runID=1310924&returnType=STATUS_TEXT&waitForStatus=FINISHED_OK by passing the obtained run ID of the previous job dynamically to this url. This status has to be read and printed on the screen. Now all this is easy to write using java and executing the java class using the JAVA EXECUTE component of Integrator ETL 3.1. My only problem is how do I pass the user credentials.
Thanks

Calling a servlets multiple times from a servlet

Hi All,
Advanced Thanks,
I have a servlet which calls another servlet to display some records. Second servlet will access some data from XML files and forwards to a JSP file. What i want is I need to call the second servlet multiple times from the the first servlet. I used RequestDispatcher to call the servlet but I can call only one time after a an exceptions is occurred like cannot forward after response is committed.
I need this scenario in the saem way because each time second servlet is called I am forwarding response to user each time records are accessed based on the request value.
request.getRequestDispatcher("sample").forward(request, response);
Any one please give me a suggestion?
Thanks in advance

What are those servlets supposed to do? Sounds like that they are doing too much, e.g. acting like business classes or utility classes or so. Refactor your code.

How to call a servlet in a Session Bean

Hi All
I have one servlet program.And i have One Sessionbean.
I want to call the servlet in the session bean.
I am using Runtime method in java to call the servlet by giving it's full
path as it's argument.
But it is not working fine.I don't know what is the Problem.
Bye
Satyam

Hi,
I don't know why you want to do that? You should be doing the other way round i.e. call your session bean from servlet.
I must say that servlets are presentation tier components and session beans are middleware components related to workflow.

How to call the RFC FM at the time of mapping

Hi Experts,
I am new to PI. I want to know How can we call the RFC function module at the time of message mapping.
Can any plz explain me?
Thanks
Karthik

First import the RFC FM by selecting import of RFC and IDOC supported button at SWC level and then provide the necessary R/3 details and get the RFC FM imported to IR .
Once this is done you can have a drop down list for the selecting the source or target message for mapping

Best practice on when to call the HTTPService?

We use HTTP calls to get data frm the server. Currently in our application we call the server on creationComplete event-and display tabs buttons depending on the data that i get from the server.
But i'm thinking to call the server at initialization event and keep the data ready by the time it comes to creationComplete/what ever works. When is it good to call the server? please update my knowledge.

Ya.. i understand.. but, What i'm thinking is to populte the data into arraycollection / keep the XML which we get and keep it ready for the completion event. Coz, what i see is, whenever i click on a button, it opens a tab on the tabNavigator and shows a canvas without any data - paralell to this a server call is made and after few moments the canvas shows the data, even though it all happens within 2-4 secs depending on the network.. I'm still concerned about those 2-4 secs.. i'm trying to bring down the time it takes to load that single page by running a few things paralelly than doing it one after the other. Any other way you could think of?
