GetOutputStream() -- Connection refused: connect
Hi, i'm doing this (inside a function)
URL receiver = new URL(url);
HttpURLConnection receiverConnection = (HttpURLConnection)(receiver.openConnection());
receiverConnection.setDoInput(true);
receiverConnection.setDoOutput(true);
receiverConnection.setRequestProperty( "Authorization", "Basic " + encodedPassword);
receiverConnection.setRequestProperty( "Content-type", "application/x-sap.rfc");
System.setProperty("javax.xml.transform.TransformerFactory", "com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
Reader rd = new StringReader(strXml);
StreamSource streamSource = new StreamSource(rd);
PrintWriter pw = new PrintWriter(receiverConnection.getOutputStream(), false);
StreamResult streamResult = new StreamResult(pw);
transformer.transform(streamSource, streamResult);
pw.flush();
pw.close();and when i do the receiverConnection.getOutputStream() it throws
"Connection refused: connect"... i'm using JDK 1.5 with tomcat 5.0...
thanks in advanced!!!
Comment out your call to setDoInput(true). See if that helps. If not, then it is probably a configuration issue on the server you are attempting to send to.

Telnet: Sending an output to the connected host.
Hi all, I have written a GUI to connect to a host using a socket. This is going to be a MUD client (for all who know what a MUD is) and I can't seem to send anything to the host. Any suggestions? Also, the code returned by the host is in some computer language at some areas. Like when there is supposed to be colour it shows a squarebox then [32mL.
This is the complete working code.
Thanks.

Problem establishing a https connection
Hi,
I have the following problem in establishing a connection to a secured webserver.
I tried to establish a connection to a secured web server from a application running in weblogic. I used the weblogic specific APIs, created a weblogic.net.http.HttpsURLConnection. I set the connection properties like setSocketFactory and used NulledTrustManager and NulledHostNameVerifier.
I then tried to get a DataOutputStream so tht i can write my xml string to tht connection, nothing really is happening. When i tried to print the headervariables it is not printing any..... I am doubtful if the connection is established....
i will attach my code....plz tell me if i am missing something out....
The same code works when i use Java APIs....they are included in the code as comments....
Actually i have a jsp file in the secure server which takes this string and sends mail to the required recipients.....
Plz help.....Thanks in Advance for all the helping minds...
In the code, the trustallcerts and hostnameverifier are classes written similar to nulledtrustmanager and nulledhostnameverifier.... ie it certifies everything and trusts everything.

}Thx for the prompt reply....But this is not solving my problem.
I am trying to establish the connection from inside a weblogic container. So i am forced to use weblogic APIs.
Also i use NulledTrustManager and NulledHostNameVerifier so i think i neednot worry about the certificates...
Weblogic APIs donot contain init method for sslcontext....So if u can see the code, i have commented these lines and set these properties using the Weblogic supported APIs.
Also the method which u specified (Using Java APIs) was working for me....problem arose when i tried to use weblogic specific APIs.
Can u go through the code once and tell me if i am missing something over there? Coz header is not getting populated, the request is not hitting the secure server
One more thing, if i use the HostNameVerifier(dummy one to verify all the hosts), it tells me tht the key chain obtained from the host is incomplete.... and throws javax.net.ssl.SSLKeyException...
If i remover hostnameverifier, the exception is not thrown, but the request is not hitting the server...
Plz help me ... i am helplessly stuck in this situation...
Thx in advance for all the helping minds..... -

How can i pass more than 1 param to servlet to show blob image
Hi
my servlet expects 2 param to SELECt an image from a blob column
public class ImageBlobServlet extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=windows-1252";
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
response.setContentType(CONTENT_TYPE);
String ImageId = request.getParameter("id");
String TipImg = request.getParameter("tip");
OutputStream os = response.getOutputStream();
Connection conn = null;
try {
Context ctx;
ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:/comp/env/jdbc/rhDS");
conn = ds.getConnection();
PreparedStatement statement = conn.prepareStatement("select FIT from " +
"RHH_FOTOS IMG " +
"where IMG.IDASSO = ? and IMG.TIM_COA = ?");
statement.setInt(1, new Integer(ImageId));
statement.setString(2, TipImg);
To display the image i tried to use:
<af:image id="ot1"
*source="/imageblobservlet?id=#{bindings.Con.inputValue}?tip=#{"EMP"}"*
shortDesc="Foto"/>
but i receive all content in the get of first param.
String ImageId = request.getParameter("id");
How can i pass one more then 1 param in EL.
Thanks in advanceHello,
seems to me you're using wrong separator for the second param into your URL:
<af:image id="ot1" source="/imageblobservlet?id=#{bindings.Con.inputValue}
tip=#{"EMP"}" shortDesc="Foto"/>
I think it should be:
<af:image id="ot1" source="/imageblobservlet?id=#{bindings.Con.inputValue}
tip=#{"EMP"}" shortDesc="Foto"/>

i have compiled the class file that i needed and i signed it too. but now it is giving me a new error and need your tip.
here is the java console loyout and my java file ((i think here is the problem in java file, something must be missing)).
thanks in advance for any help.

out.print(postData);
out.flush();
String lengthString = String.valueOf(byteStream.size());
c.setRequestProperty("Content-Length", lengthString);

Long Raw Picture not showing in adf
I have used following servlet to show long raw picture. the problem is in line
Blob blob = rs.getBlob("PLAN_PIC");
The oracle column is Long Raw and in ADF table this column shows as Raw. I have tried to use Raw class but could not identify proper functions. For example I used Long blob=rs.getLong("PLAN_PIC"); it is ok but then how to get its buffered binary stream because getBinaryStream() does not work for long. I also tried to use to_blob function to convert long raw column to blob but it also gives ora-0932 error. The same table shows picture in oracle form and also Dot Net developer showed the same picture. Kindly help.

How to show long raw picture in adf jsp
Pictures are stored in long raw column in oracle database. I have followed to show picture based on servlet to retrieve image from blob column but to no success. Kindly help.
Thanks for helping.
I have already used following servlet but no picture. I think problem is in specific line because image is in Long Raw instead of Blob..
Blob blob = rs.getBlob("PLAN_PIC");

How to test ImageServlet on JDev 10.1.3 (OCJ4) ?
Hello,
I download StoreFront.zip OTN sample and modify Imageservlet class to read blob data into an image object on my jspx.
I place a breakpoint in ImageServlet's source, and run my test with debug mode. The jspx is displayed but the ImageServlet is not executed !
DO I NEED TO CONFIGURE SOMETHING TO MAKE IMAGESERVLET ACCESSIBLE TO MY JSPX ?
Thanks.
1. Image object with test value of 21321955
....... and so on
<af:objectImage height="200" width="180"
binding="#{backing_app_Tax_MissionTax.objectImage1}"
id="objectImage1"
source="/imageservlet?personid=21321955"/>
...... and so on
2. ImageServlet class
public class ImageServlet extends HttpServlet {
private static final String CONTENT_TYPE =
"image/jpg; charset=utf-8";
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
response.setContentType(CONTENT_TYPE);
response.setContentType(CONTENT_TYPE);
String personId = request.getParameter("personid");
if (personId == null) {
return;
OutputStream os = response.getOutputStream();
Connection conn = null;
try {
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/P03DB");
conn = ds.getConnection();
PreparedStatement statement = conn.prepareStatement(
"SELECT PersonImage.PID, " +
" PersonImage.PORTRAIT " +
"FROM IMAGE.PORTRAITS PersonImage " +
"WHERE PersonImage.PID = ?");
statement.setInt(10, new Integer(personId));
ResultSet rs = statement.executeQuery();
if (rs.next()) {
Blob blob = rs.getBlob("PORTRAIT");
BufferedInputStream in = new BufferedInputStream (blob.getBinaryStream());
int b; byte[] buffer = new byte[4096];
while ((b = in.read(buffer, 0, 4096)) != -1) { os.write(buffer, 0, b); }
os.close();
} catch (Exception e){
e.printStackTrace();
} finally {
try{
if (conn != null){
conn.close();
} catch (SQLException sqle){
sqle.printStackTrace();
}That's why I asked whether you have tried to invoke the servlet directly. It would have shown that your web.xml configuration wasn't correct for that.
By packaging I mean that the JSPX and the Servlet are in the same project or web application (WAR).

Where can I find the description of the codes returned by exitValue()?
Hi Everybody,
I have a java porgram on HP/UX and this program executes the OS level commands and exe file on HP UNIX. When I supply "/usr/bin ls -l" as a param to this program it executes it very well.
But if I pass the "/utils/Myapp/app arg1 arg2" as a parameter it returns some non zero codes
I tried several ways to make it work and I even harcoded the "/utils/Myapp/app arg1 arg2" in the program but it never executes it properly and I got the following return Code return by exitvalue() during my hit and trial method.
255,17,15,12
Does any one have clue what are they.
Note: When I executes /utils/Myapp/app arg1 arg2" from the UNIX prompt it works fine
The java program is given below.
Pl help
Thanks
Yatsomy.
This is my first program in JAVA.
import java.lang.Runtime;
import java.lang.Process;
import java.io.IOException;
import java.lang.InterruptedException;
class executecmd {
public static void main(String args[]) {
System.out.println("In main");
try {
/* Execute the command using the Runtime object and get the
Process which controls this command */
Process p = Runtime.getRuntime().exec(args[0]);
/* Use the following code to wait for the process to finish
and check the return code from the process */
try {
p.waitFor();
/* Handle exceptions for waitFor() */
} catch (InterruptedException intexc) {
System.out.println("Interrupted Exception on waitFor: " + intexc.getMessage());
System.out.println("Return code from process"+ p.exitValue());
System.out.println("Done executing");
/* Handle the exceptions for exec() */
} catch (IOException e) {
System.out.println("IO Exception from exec : " + e.getMessage());
e.printStackTrace();1. exitValue() codes are the numeric codes returned by native applications you're calling: the meaning of this code is both application and platform dependant (it has nothing to do with java), so you should try to find those info in "app" documentation, or in HP Unix standard docs.
2. I think you'd better "debug" the Runtime.exec() behaviour by capturing stdout and especially stderr of the spawned process: doing so, you will be able to see error messages printed out by called applications or commands...
It's very simple using this small class:
/** connects I/O streams, just like a pipe :-)
* @author: Giorgio Maone
class Pipe {
private InputStream in;
private OutputStream out;
public Pipe(InputStream in, OutputStream out) {
this.in=in; this.out=out;
public void connect() {
new Thread() {
public void run() {
try {
for(int b;(b=in.read())!=-1;) {
out.write(b);
out.flush();
} catch(IOException ex) {}
}.start();
}So you can do this:
Process p = Runtime.getRuntime().exec(args[0]);
new Pipe(p.getInputStream(),System.out).connect();
new Pipe(p.getErrorStream(),System.out).connect();
new Pipe(System.in,p.getOutputStream()).connect();
try {
System.out.println("Exit code: "+p.waitFor());
} catch(InterruptedException ex) {}If you want to use a "smart wrapper" on Runtime.exec(), feel free to use my MultiExec class:
/** executes multiple commands in one shell
* @author: Giorgio Maone
import java.io.*;
public class MultiExec {
static final boolean IS_WIN=System.getProperty("os.name").toLowerCase().indexOf("win")==0;
protected String shell=IS_WIN?"":"sh";
public void setShell(String s) {
shell=s;
public String getShell() {
return shell;
public Process exec(String cmds[]) throws IOException {
File f=File.createTempFile("muexec",".bat");
PrintWriter out=new PrintWriter(new FileWriter(f));
if(IS_WIN) out.println("@echo off");
for(int j=0,len=cmds.length; j<len; j++)
out.println(cmds[j]);
out.close();
f.deleteOnExit();
return Runtime.getRuntime().exec(shell+" "+f.getCanonicalPath());
public int execAndWait(String cmds[]) throws IOException {
Process p=exec(cmds);
new Pipe(p.getInputStream(),System.out).connect();
new Pipe(p.getErrorStream(),System.out).connect();
new Pipe(System.in,p.getOutputStream()).connect();
int exitCode=-1;
try {
exitCode=p.waitFor();
} catch(InterruptedException ex) {}
return exitCode;
static class Pipe {
private InputStream in;
private OutputStream out;
public Pipe(InputStream in, OutputStream out) {
this.in=in; this.out=out;
public void connect() {
new Thread() {
public void run() {
try {
for(int b;(b=in.read())!=-1;) {
out.write(b);
out.flush();

Servlet Database I/O: How to "lock" a record being updated ?
Say you have a servlet that displays a list of customers in HTML page, and a button on each customer to click to bring up another page (servlet generated) with the customer info to edit. The customer info is in a database file (could be Access or ORACLE). User makes any changes and clicks a button to update the customer record (with a servlet).
How do you prevent two users from editing the same customer record at the same time? I do not want to lock the whole file, just a record.
Any pointers towards info about this subject appreciated.
Walk Goodsridharranganathan, does your technique assume that the read operation is locked, so that two users cannot obtain the same value of LockCounter?
I have some questions relevant to the following code:
public class theServlet extends HttpServlet

} // end class HelperI should say that the UserRecords table now contains about 5000 records (this will grow in increments of 5000), many of which have null user_id. If the value is not null, then it contains a userid. A user can have either zero or one entry in the table.
Here are my questions regarding the above:
1. In the servlet, each thread will have its own instance of Helper and of Connection, correct?
2. I want to ensure that only one thread can update a particular UserRecords table record at a time. In the getUserRecord method, please note the line where field1Val is assigned, just above the capitalized QUESTION comment. Is it possible that two threads could have the same value of field1Val at the same time?
3. When you set the transaction isolation level for connection1, does that prevent other threads that are using other connections to the database from accessing records being updated by the thread using connection1?
4. As you can see, I am considering passing a reference to the servlet instance into the getUserRecords method and synchronizing the update statement on the servlet instance. Will that ensure only one thread at a time can update the record, without using the transaction isolation code?
Thanks in advance for your answer. -
I have to call native applications from within my java application (using the Runtime.getRuntime().exec() method). That works fine but I need to change the current directory path to a specific path.
How it is done to change the current directory path with java ?
