Gettig SOAPBody as string or as InputStream

I am receiving SOAP messages over jms Queues. After receiving messages I need to get the content of SOAP:Body as a String or as InputStream. How can this be done?

depending on the type of message u're receiving, by that i mean the class of the message, e.g. OMElement?

It's posible inject a String in a InputStream??

Hi all.
I'm beginning work with XML, and in this moment i need process not very big xml FILES, this because files arrives in very short time, my problem now is with SAX/DOM, in general this process "files" and i have a string variable with the xml inside!!
It's possible inject this String in a InputStream to don't create a temp file???
Ideas to work and process xml directly (links to read about this) is welcome.
thank's

How to get InputStream from String ?

Hi !
I want to get InputStream object from String.
String str = "balabalabala";
InputStream stream = getInputStream(str);
How to realize getInputStream(str) function ?
Thanks!

The preferred method nowadays is to use Readers and Writers for String data - hence StringReader(String). If you're going to operate on the InputStream directly, then I'd modify your code to use the Reader calls and go that route.
If, however, you need to pass the InputStream to some other piece of API that requires an InputStream instead of a Reader, then the ByteArrayInputStream is probably your best bet. StringBufferInputStream is deprecated because it doesn't work reliably in the face of many character encodings.
Speaking of encodings - never call Strng.getBytes() - always use the getBytes(character-encoding) version, so you KNOW what encoding you're getting!

String to inputStream

Hi I'm trying to "convert a string to an inputstream. I'm working with the JTidy API which needs an inputstream for doing the parseDOM(var,var) method, everything works fine when my data comes from a file and when I use FileInputStream but it wont work with the InputStream.
It looks to me that the InputStream is empty. What I'm basically doing is:
String myInputStream = "blahdiblah";
try{
System.out.println("myInputStream:" + + myInputStream.read()); // gives me 98 the value of the first char
}catch( Exception e ) {
System.err.println("error:" + e.toString() );
InputStream in = null;
StreamSource myStreamSource = new StreamSource(myInputStream);
in = myStreamSource.getInputStream();
try{
System.out.println("1 test" + + in.read()); // gives me nothing back, while it should give 98
}catch( Exception e ) {
System.err.println("error:" + e.toString() );
Why does the first read-method returns the Decimal ASCII of the letter "b" and the second does not?
Can anyone tell me what I'm doing wrong? I'm not really familiar with these streaming stuff, any help would be great !

String data = "sfgafgagafg";

Strange exception when deploying BC4J as EJB in 8i CORBA.BAD_PARAM: null Strings are

I am trying to deploy BC4J as Ejb to 8i (8.1.6). I use the following deployment method with j: my Jdev root.
setjboenv j: ejb8i
loadjava - u user/passwd@host:port:sid - thin -v - r grant "SYS,PUBLIC" j:lib\xmlparserv2.jar
loadjava - u user/passwd@host:port:sid - thin -v - r grant "SYS,PUBLIC" j:lib\jbomt.zip
loadjava - u user/passwd@host:port:sid - thin -v - r grant "SYS,PUBLIC" j:lib\jboejb.jarI then create a deployment profile for ejb 8i with the ide. (Without deploying)
I then use loadjava outside the IDE to deploy the 2 jar files created
MyProject1CommonEJB.jar
and
Myproject1.jar
I then use the ide again to deploy the bean profile
Package1ModuleServerEJB.prf
The last step fails with the error :
Publishing EJBHome...org.omg.CORBA.BAD_PARAM: null Strings are illegal in IIOP. Please correct your application or run the ORB in backward compatibility mode. minor code: 0 completed: No
void oracle.aurora.ejb.deployment.GenerateEjb.invoke()

void oracle.aurora.ejb.deployment.GenerateEjb.main(java.lang.String[])
Exception in thread main
Strangely, when I test this EJB with the tester (middle tier = remote ejb) it works, but from JSP's I get an application error : "Unknown Exception"
I am using Jdev 3.1
Also using the deploy option when creating the deployment profile fails apparantly due to the missing grant "SYS,PUBLIC" when loading classes to the database before deploying the bean.
What can be done ?
null

Hi Blaise
Thanks for the reply. I have tried to do the complete deployment from within Jdev, but now I get the following error right at the end of the deployment.
/BC4J1AppModuleEjb/EjbObject_RemoteBC4J1AppModuleEjb:ORA-29535: source requires recompilationjava.lang.NullPointerException at sun.tools.java.Environment.error(Environment.java) at sun.tools.java.Environment.error(Environment.java) at sun.tools.java.Environment.error(Environment.java) ..... etc.
I have tried to deploy to a clean schema with the java privilages granted as described in the Jdev release notes.
I included the following libraries in my project :
JBO JDBC816 PATCH
JBO OSQL Domains
JDeveloper Runtime
Oracle 8.1.6 JDBC
Connection Manager
JBO Runtime
JBO VB Runtime
JBO 8i Runtime
SQLJ Runtime
JBO 8i Client
JBO Vanilla Domains
JBO EJB Runtime
JServer
Oracle XML SQL Utility
ORACLE XML Parser 2.0
Then I just used the deployment wizzard

InputStream hung from Runtime.getRuntime().exec

Dear all,
I am trying to use the following code to run a Runtime.getRuntime().exec("my_selection.exe") method and redirect all the output from the process to my JTextArea.
My program is an executable called "my_selection.exe", which runs under DOS something like:
My Selection Utilities:
type the command -
o : open an item
l : list subitems
q : exit
Please select your options:But when I run my Test program, the above selection menu does not show in my JTextArea. Only after I type q (which is exit command in my_selection), will all the output shown in TextArea.
I tested the inputstream.available(), but it always == 0.
Anyone can help point me out what is wrong here?
BTW, when I use the same program to run "copy a.txt a" by exec("cmd.exe"), it works ok, no matter whether it prompts for owerwrite the existing file or not.
Many thanks!

InputStream only gets to 8192 bytes

I'm guessing this must be something simple I don't understand about InputStreams, but the following code only reads "README.txt" to 8192 bytes, despite the fact that fis.available() returns somewhere around 13000:
void loadDoc(){
    String str;
    try{
        InputStream is = getClass().getResourceAsStream("README.txt");
        int size = is.available();
        byte[] bytes = new byte [size];
        int read = is.read(bytes);
        System.err.println("Available:" + size + "\nRead: " + read);
        is.close();
        str = new String(bytes);
    } catch (Exception e){
        System.err.println(e);
        str = "The file README.txt could not be found; it may have been deleted or moved.\n";
    displayArea.setText(str);
    displayArea.setCaretPosition(0);
}I'm suspicious, since 8192 is a power of 2, which makes me think that it's not stopping at some arbitrary point or due to something in the file. What's going on here?

From what the docs for available() say, I'd have thought it would read the full 13000 or whatever. It seems like it's blocking sooner than it's supposed to.
I'd guess one of three things, in order of decreasing likelihood:
* "Blocking" has a specific meaning that doesn't extend to what's happening here, which I'd guess is simply that some underlying buffer has a size of 8k, so that's all that can be deliverd at once.
* You're not running the code you think you are, or have otherwise misinterpreted what you observed.
* There's a bug in the stream implementation.
Presumably if you loop here, you'll get the remaining bytes on the next read (if it is in fact the first point above that's causing this). Decorating the InputStream with a BufferedInputStream might do this for you, but I wouldn't count on it--you'd still have to put the reading in a loop.
On other alternative would be to turn the URL into a URI, the URI into a File, and then build a RandomAccessFile from the File, and use ReadFully. That feels like overkil to me, though.

Shell commands from JSP after Forms migration

During application migration from forms 9i to JSP & BC4J, I have to code the following Forms code into my JSP application.This is for a button pressed trigger.
DECLARE
RENAME_STRING VARCHAR2(120):= 'RENAME C:\BRC\PDATA' ||:DRAWING_ACCOUNTS.ACCOUNT_ID|| '.TXT P' || :DRAWING_ACCOUNTS.ACCOUNT_ID || TO_CHAR(SYSDATE,'DDMMYY')|| '.txt';
BEGIN
HOST( RENAME_STRING, no_screen );
web.show_document( 'http://hostname/selectfile.html', '_new');
     IF NOT Form_Success THEN
          Message('Error -- File not Renamed.');
     END IF;
END;
How can I do this simple sending of OS commands in JSP, any ideas?

Hi,
Not only rename commands but I have to pass several other os commands like 'sqlldr' for data upload as well. Therefore, I need a reusable piece of code for that. I have acheived some way for that using the following code.
put the following file in that package.

Portal application can't read request info

hi all,
i use portal application for change portal user's infos.but when i sent request info,
request.getServletRequest().getInputStream() method is cutting my sending line after 90. character.
in R3 side i use HTTP_POST function and fill request info (table paramater).
i tried to send 2 line(less than 90 character) in request info, but i can't read second line in java code.
Is IPortalComponentRequest accept only 90 character ?
how can i solve this problem , any idea ?
my code is below, variable "str" is filling only first 90 character;
     protected void doOnNodeReady(
               IPortalComponentRequest request,
               IEvent event) {
     String str = "";
     try {
          InputStream is = request.getServletRequest().getInputStream();
          InputStreamReader isr = new InputStreamReader(is);
          int c;
          while ((c = isr.read()) > -1) {
          str = str + (char) c;
            } catch (java.io.IOException ex) {
             str = "Error accessing input stream";
thanks

New discovery...If I shut down all instances of IE on my machine, then reopen my test form, it works. Once. The second time I try it I get the same peculiar behavior again, until I again shut down all instances of IE.

Runtime.exec("Perl Script writing and reading on I/O"), handling Streams

Hi all !!
In a first place : sorry for my english if it's not really understandable but I try to do as good as possible !
I'm writing a GUI with Swing that will allow (in one of my multiple tables) the user to run a Perl Script.
This Perl Script ask the user to choose a Folder ... then read all the files in this folder and for each file (xml File), extract the datas and put them in a database. But when a file that has to be inserted in the database contains this line : <Template_Used name="ST1.mtt"> and if the Template table in my database doesn't have the "ST1.mtt" stored ... the Perl Script ask to the user to give him the path of the file "ST1.mtt" so that the script can put the "ST1.mtt template" datas in the database.
This script runs well when it is from a windows console.
But I need a graphic interface !!!
So I created a JButton "Process a folder".
When the button is pressed, a JFileChooser appears and ask the user which Folder has to be processed.
Then a Process is created with the command : ("cmd.exe /C \"C:\\Program Files\\Fluke\\Ansur\\ProcessFolder.bat\").
The BatFile :
{code}cd C:\Documents and Settings\tsd\Desktop\Gael-Project\Project_Files
perl Process.pl
exit{code}
At this moment everything is working well.
But my Process.pl (which is 300 lines long ... and that you don't even want to hear about), ask in a first time the Path of the folder to process and sometimes ask the path to a file (a template file).
So I need to read and wirte on the STDIN/STDOUT during the exec of the Process.
In order to handle this I created two different threads : one reading the Process.getInputStream with a BufferedReader and one other writing on the Process.getOutputStream with a PrintWrinter.
What I need to do is :
When I read a line from the InputStream saying "I need the path of the ST1.mtt file", I should run a JFileChooser ... the user find the file in the computer ... and I write in the OutputStream the path of the file, so that my Perl Script doesn't have un Unitialised value on <STDIN> and can continue to process !!
I'm pretty sure it's possible ... because at the moment I just used a trick :
When the user push the "process a folder" button, I write the paths in the OutputStream before than the script needs it and it works !
But I need to write in the OutputStream only when it is time !!!
Any idea ??
Here are some parts of my code :
{code}
String filename = File.separator+"tmp";
          JFileChooser fc = new JFileChooser(new File(filename));
          fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY );
          // Show open dialog; this method does not return until the dialog is closed
     fc.showOpenDialog(null);
     Folder = fc.getSelectedFile();

     errorGobbler = new
     StreamGobbler(proc.getErrorStream(), "ERROR");
     // any input?
     inputGobbler = new

String comp = "Please enter the exact path of the directory that contains the files you want to process.";
while ( (line = br.readLine()) != null){
     if (type.equals("INPUT")){
          chaine+=line+"\n";
     if (line.equals(comp)) {
          System.out.println("give directory");RUN A JFILECHOOSER AND GIVE THE DIRECTORY TO THE OUTPUTSTREAM
System.out.println(type + ">" + line);
is.close ();
catch (IOException ioe){
     ioe.printStackTrace();
{code}
And here is an example of a simple perl script that could be used (it s a simple one !!) :
{code}
#!/usr/bin/perl -w
use strict;
print "Please enter the exact path of the directory that contains the files you want to process.\n";
my $dir= <STDIN>;
chomp ($dir);
print "titallala $dir";
if (the template of the file is not in the database){
print "Please give me the template so that I can put it in the database";
$dir= <STDIN>;
chomp ($dir);
{code}
Thank you for your help ... if it's possible to help me !!

BalusC -- The line that gives me my NullPointerException is when I call the "DisplayProduct()" method. Its a dumb question, but with NetBeans how do I find out which reference could be null? I'm not very familiar with how NetBeans works with finding out how to debug. Any help you can give me would be greatly appreciated.The IDE is com-plete-ly irrelevant. It's all about the source code.
Do you understand anyway when and why a NullPointerException is been thrown? It is a subclass of RuntimeException and those kind of exceptions are very trival and generally indicate an design/logic/thinking fault in your code.
SomeObject someObject = null; // The someObject reference is null.
someObject.doSomething(); // Invoking a reference which is null would throw NPE.

Runtime exec freezes: exec target is a executable .jar that requires stdin

I am having a problem with the Runtime.getRuntime().exec methodology in the following scenerio:
-- Exec.class is a program that uses a StreamGobbler to display stdout to the screen
-- ReadInput.class is a program that requires the user enter information via the console, using stdin
When I try to do this, the ReadInput.class locks up and freezes, presumably because its trying to use stdin which already has been gobbled up by the Exec.class ???
Here is my code, for example, that I run with the following command (on Windows XP) :
start.bat
@echo off
echo.
javac *.java
echo First, test the Exec.class to see if it works
echo.
java Exec "dir *.java"
echo.
echo Then, try to run a program that wants the stdin (click a key to continue)
echo.
pause>nul
java Exec "java -cp . ReadInput"
echo.
echo (click a key to end)
pause>nul

Added [ code] tags to make the code readable.

When you call proc.getInputStream(), you are opening an InputStream in your app to read from the process's stdout.
If that process "needs stdin", that is, if it normally runs by a user typing stuff at a terminal after it launches, then you have to call proc.getOutputStream() to get an OutputStream that your app can use to feed the process's stdin. So if you're trying to have your app read from the terminal (your app's stdin/System.in) and push that to the process you're launching, then after reading a line from System.in, your app would need to write that line to the OutputStream that you get from proc.getOutputStream().
