Servlet to output a string

It has been a long time since I worked on Java. Appreciate if anyone can tell me if there are other ways to output a string from a servlet. I tried using response.setContextType("text/plain");Thanks in advance.

Problem in outputting a string into a file

Hi guys,
I tried to output a string to a file. The string is 'Size : 30u201D X 13 ½u201D X17 ¾u201D(H)'.
However, with this code :
l_file = '/erp/reports/testgk.txt'.
l_str = 'Size : 30u201D X 13 ½u201D X17 ¾u201D(H)'.
OPEN DATASET l_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
TRANSFER l_str TO l_file.
It returned me a weird string: 'Size : 30M-bM-@M-] X 13 M-BM-=M-bM-@M-] X17 M-BM->M-bM-@M-](H)'
Would you please let me know how to solve this problem?
Thanks, gk

Hello gk,
I tried this code & works fine for me though:
DATA: v_data TYPE string VALUE ' 30u201D X 13 ½u201D X17 ¾u201D(H)',
v_file TYPE string VALUE
'\glbwi720InterfaceID2100I_MB_207INsdn.txt'.
OPEN DATASET v_file FOR OUTPUT
IN TEXT MODE
ENCODING DEFAULT.
IF sy-subrc = 0.
TRANSFER v_data TO v_file.
CLOSE DATASET v_file.
ENDIF.
Looks like the "usual" ENCODING problem

Multiple String to search on the "Scan Output: Abnormal String" item

in the job definition on the run tab on the "option scan output: abnormal string" we use this command pipe to search for the string to force the job to get abnormal status. there are some case that when the job runs and the program being called throws error message other than the string "error". for example it throws "invalid" string to indicate the program has error out. is there a work around to include more than one strings on the commnad pipe? please adivse.
thanks,
warren

Just put a comma between the strings. If your strings contain spaces you need to put quotes around it. see below.
"Not connected","Login failed","File not found","The system cannot find the file specified","Access is denied","Unknown host","Invalid command"

Best way to output a string

I have a JAVA Bean, and I need to output a string to the JSP output, how to do that? I am new to the JAVA world.
public String retrieveBottomLine()
     bottomLine = bottomLineDAO.retrieveBottomLine(FacesUtil.getServletRequest().getParameter("bottomLineKey"));
     bottomLine.setInShoppingCart(FacesUtil.getServletRequest().getParameter("inCart").equals("true"));
     calculatedItem = null;
String customer=FacesUtil.getServletRequest().getParameter("bottomLineCustomer");
System.out.println(customer); // <---this output the string fine.
this.customer = customer;
     return "bottomLine";
public BottomLine getBottomLine()
return bottomLine;
public void setBottomLine(BottomLine value)
bottomLine = value;
public String getCustomer() {
return customer;
public void setCustomer(String customer) {
this.customer = customer;
My jsp page
<%@ page contentType="text/html; charset=utf-8" language="java" %>
<html>
<head>
<jsp:useBean id="simple" class="com.mdi.air.formBeans.BottomLineBean" />
</jsp:useBean>
<td style="vertical-align: top;" height="18"><strong>Customer</strong></td>
<td colspan="5" style="vertical-align: top;"><jsp:getProperty name = "customer" property = "customer"/></td>
<td style="vertical-align: top;"> </td>
<td style="vertical-align: top;"> </td>
<td style="vertical-align: top;"> </td>
<td style="vertical-align: top;"> </td>
</body>
</html>
Customer is not coming up.

in my backing bean.
public String retrieveBottomLine()
bottomLine = bottomLineDAO.retrieveBottomLine(FacesUtil.getServletRequest().getParameter("bottomLineKey"));
bottomLine.setInShoppingCart(FacesUtil.getServletRequest().getParameter("inCart").equals("true"));
calculatedItem = null;
String customer=FacesUtil.getServletRequest().getParameter("bottomLineCustomer");
System.out.println(customer);
this.customer = customer;
HttpSession session = (HttpSession)FacesContext.getCurrentInstance().getExternalContext().getSession(false);
session.setAttribute("simple", bottomLine);
return "bottomLine";
I now get this error
Error 500: com/mdi/air/domain/BottomLine incompatible with com/mdi/air/formBeans/BottomLineBean
All I need is to put the "customer" value string and put it into the JSP page.

How to display an output in string data type in an applet

hello there..may i know how to display an output of string type in an applet

thanks.i'll try

How can I convert output data (string?) from GPIB-read to an 1D array?

Hello all,
I am reading a displayed waveform from my Tektronix Oscilloscope (TDS3032) via the GPIB Read VI. The format of the waveform data is: positive integer data-point representation with the most significant byte transferred first (2 bytes per data point).
The output data of GPIB-Read looks like a string(?) where the integer numbers and a sign like the euro-currency sign are seperated by spaces e.g. #5200004C3 4 4 4 4 3C3C3........ (C represents the euro-currency sign).
How can I convert this waveform data into a 1D/2D array of real double floatingpoint numbers (DBL) so I can handle the waveform data for data-analysis?
It would be very nice if someone know the solution for this.

hanks

Hi,
First of all, I'm assuming you are using LabVIEW.
The first you need to do is parse the string returned by the instrument. In this case you need to search for the known symbols in the string (like the euro sign) and chop the string to get the numeric strings. Here are some examples on parsing from www.ni.com:
Keyword Search: parsing
Once you parse the numeric strings you can use the "String/number conversion VIs" in the String pallette.
Hope this helps.

Save servlet html output as jpeg.

Hello everybody,
I have a servlet that creates an html page.
The html consits of information from a database and displays a data sheet with images and text.
I have been asked if the outputed data sheet can be saved as an image (jpeg).
Is this possible?
Thanks.

I am can of confused how this works
I know that there is more to do in order to create an
image.First you have to make a desition, what do you need?
* if you only want to save a data sheet i think the better solution is a Excel format file, for this yo coul take a look at http://jakarta.apache.org/poi/hssf/index.html
* if you want to generate a pdf with images, tables, etc. yo should take a look at http://xml.apache.org/fop/
* if you want to create a custom image i cant help you
the proces to generate excel isnt dificult but to make a pdf is a little hard. but if you read the documentation and the examples you shouldnt have problems

Output variable string or number consecutively

Hello,
I have an input signal of telephone digits and I am trying to output the digits on a string or number indicator one by one as they come out so that at the end I would have a full telephone number. I understand the logic to program it but I can't quite get a way to do it visually in LabVIEW. Can you help?
Thanks,
LD

I'm trying to detect an 11-digit telephone number coming from a cable. I'm using an NI USB 6008 unit to get the signal in and then work out the numbers. What I have right now is LEDs flashing up for each number from 0 to 9.
I've attached my file for reference.
I have two side questions I'd like to ask. First one is about DAQ Assistant: you know when you're setting up the DAQ Assistant, there's sampling rate, acquisition mode and samples to read parameters, what exactly is the samples to read parameter? The help information said that it's the number of samples specified to read for N Samples acquisition mode or the buffer size for Continuous sampling acquisition mode.
I've got a bit confused about this samples to read parameter because when I tried putting it at high values like 10k, the output of the signal on the graph indicator was going really slow, like it would take snap shots at long intervals. And when putting the parameter at lower values, the signal becomes more continuous. The same actually goes for the sampling rate which is even stranger.
The second question is actually related to the above question. Every digit is dialed (automatically) every 40ms - on the oscilloscope it's like 40ms of waves and then 40ms rest and then 40ms of waves again, so that's like a pulse going at 12.5 Hz. But the waveforms have frequency components within the range of 0.5k to 2k. So my question is what determines the values I'd want to use for the above parameters (if any)?
Sorry for the shabby drawing

Can't see my Servlet/JSP outputs

{color:#0000ff}Hello there Java gurus,
I'm really excited about Java but there seems to be something i'm missing out that is slowing me down. I understand the logic behind the Servlet and JSP technologies - having context root in the webapps subdirectory of the Apache Tomcat, placing other directories like servlets, WEB-INF, classes etc in their respective places and copying .class, .xml, and .html into the proper directory of webapps subdirectories- but still I can't execute properly to view the outputs of even the simplest Servlet and JSP codes.
When I tried compiling my Servlet Java file to produce a .class file, it gave an error of "javax.servlet does not exist". What can I do again to make me execute my Servlets, because there's truely no javax.servlet in the Java subdirectory of my Program Files.
Thanks in advance for making this guy smile.

Thanks cutton_m for the response, but if you can be clearer on how to get the .jar files or any other file that'd help, i'd be happier. My jakarta-tomcat-5.0.25is successfully installed, and I really don't understand what u mean by j2ee libraries coming with the tomcat's container.
You need the jars in your classpath.
The jars came with the J2EE container - in your case tomcat.
Just what should I do to get the output of my Servlets/JSP codes viewable?Get to build first would be a start.

Possible? output a string from a java program into a running program

I'm not sure if it is plausible, but this is my dilemma. My java program searches for street names in a specific region, then outputs the nearest street. I would like to synch this up with Google Earth, and output the street name into it, so it would go ahead and be able to search it right away. Is this possible, or should I attempt some other route?

Check out my runCmd method. It gives an example of running another program and listening for the output. I built this to run javac and show the output in my custom editor.
You'll see some classes in here that are not standard java classes, in particular InfoFetcher. Don't worry, this is just a utility I wrote for convenient handling of inputstreams. You can handle the inputstreams without it, but if you really want it, it's probably posted somewhere in these forums.
        private void runCmd(String cmd) {
             try {
                  System.out.println("cmd: " + cmd);
                  Process p = Runtime.getRuntime().exec(cmd);
                  InputStream stream = p.getInputStream();
                  InputStream stream2 = p.getErrorStream();
                  InfoFetcher info = new InfoFetcher(stream, new byte[512], 500);
                  InputStreamListener l = new InputStreamListener() {
                       int currentLength = 0;

                            String str = new String(ev.buffer, currentLength, ev.getBytesRetrieved());
                            currentLength = ev.getBytesRetrieved();
                            System.out.print(str);
                  info.addInputStreamListener(l);
                  Thread t = new Thread(info);
                  t.start();

Output custom string to SAX TransformerHandler

Hi
How can I output a custom String to a SAX TransformerHandler? I don't think my string is valid XML but I want to add it anyway.
The String I want to add is: "<?import namespace="t" implementation="#default#time2">"
Can I do it by writing using the characters method? E.g. something close to:
myTransformerHandler.characters("<?import namespace=\"t\" implementation=\"#default#time2\">".toCharArray(),
0,
"<import namespace=\"t\" implementation=\"#default#time2\">".length()); This doesn't work because the < are replaced with < etc.
Thanks
/Kristofer

Maybe this question was too easy to deserve an answer or perhaps it was not answered because I was asking the wrong question. Anyways.. Elements with questionmarks are really "XML processing instructions" and the line above can be added with the line:
myTransformerHandler.processingInstruction("import", "namespace=\"t\" implementation=\"#default#time2\"");

Servlet: incremental output

Dear All,
I have the following question.
I wrote a servlet that retreives about 20000 rows from my database and I have to show them on my Internet Explorer.
I have a for cycle that writes in the ServletOutputStream:
ServletOutputStream out = response.getOutputStream();
for (int i = 0; i < customerCount; i++)
out.print(getResultsRowHtml(i));
I would like to speed up the output (killing the wait-time) forcing the browser to render row by row ...
I tried this
ServletOutputStream out = response.getOutputStream();
for (int i = 0; i < customerCount; i++)
out.print(getResultsRowHtml(i));
out.flush();
but nothing happens. The browser shows the page as soon as the servlet reaches out.close() method.
Any idea?
REgards,
Tommaso T.

You could also try SET PAUSE >>> PAUSE ON. I have "SET PAUSE >>>" in my login.sql so that whenever I "SET PAUSE ON", I get ">>>" as the continuation prompt instead of the default (no prompt).
A nested-loop type of execution plan will tend to return rows as it fetches them, while a hash-join plan or one that uses sorting will usually have to finish processing all the rows before it can return any. This is the idea behind the ALL_ROWS and FIRST_ROWS hints.
