Can i write an Object back as an http response.
can i write an Object back as an http response.
my device will send an object to the servlet and in response i need to send an object. is this possible... can i write a sample program to simulate the device.
Yes, though your object must be Serializable.
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
// code here for real work: Assume obj is the object you want to send back
try {
ObjectOutputStream oos =
new ObjectOutputStream(res.getOutputStream());
oos.writeObject(obj);
oos.close();
} catch (IOException exc) {
exc.printStackTrace();
}

How can I write new objects to the existing file with already written objec
Hi,
I've got a problem in my app.
Namely, my app stores data as objects written to the files. Everything is OK, when I write some data (objects of a class defined by me) to the file (by using writeObject method from ObjectOutputStream) and then I'm reading it sequencially by the corresponding readObject method (from ObjectInputStream).
Problems start when I add new objects to the already existing file (to the end of this file). Then, when I'm trying to read newly written data, I get an exception:
java.io.StreamCorruptedException
at java.io.ObjectInputStream.readObject0(Unknown Source)
at java.io.ObjectInputStream.readObject(Unknown Source)
Is there any method to avoid corrupting the stream? Maybe it is a silly problem, but I really can't cope with it! How can I write new objects to the existing file with already written objects?
If anyone of you know something about this issue, please help!
JaiHere is a piece of sample codes. You can save the bytes read from the object by invoking save(byte[] b), and load the last inserted object by invoking load.

Can we write client object model code with Server object model?
Hi everyone,
I have to create one timer job using client object model (C#) in Sharepoint 2010 template on feature activation. Is it possible to write the code of client object in sharepoint empty project to create timer job? If yes/no? then why?
Thanks in advance!!!Hi ShindeK,
Yes you can used CSOM in Sharepoint but Timer jobs run directly on the server. The Client Side Object Model is a wrapper that brokers its calls to the server via the built in web services that SharePoint provides.
You will not get any performance gains in this scenario using CSOM. You should use the full server object model of SharePoint
SharePoint 2010 also has three Client Object Models (Managed, Silverlight, JavaScript) which are meant to be used by code accessing SharePoint remotely.
--You can also used powershell script in timer job
Chekc the link which cann help you step by step CSOM in Sharepoint timer job

Serialization question: can't write an object
this may be a simple question but I do need to find out what's wrong with the object I am trying to serialize:
The method (included) I use to write object works fine for some simple objects but stops without giving any message for some complex objects. It stops at "out.writeObject(obj)". Is there any other exceptions need to be caught or something else. Thanks a lot.
public void writeAnObject(Object obj) {
ObjectOutputStream out = null;
try {
out = new ObjectOutputStream(new FileOutputStream("obj.saved"));
out.writeObject(obj);
out.close();
} catch (FileNotFoundException e) {
System.err.println("Caught FileNotFoundException");
e.printStackTrace(System.err);
} catch (IOException e) {
System.err.println("Caught IOException ");
e.printStackTrace(System.err);Ok, one last thing... don't know if it will make any differance but why not?! This is a class that I used successfully in several projects when serializising Collections to file:
* @author Andrew
* @version 1.0 (2000-11-24)
public class PersistentStorage {
// The objectoutputstream
private ObjectOutputStream out;
// The objectinputstream
private ObjectInputStream in;
* This method saves a collection persistent to specified file.
* @param obj The collection we want to save.
public void saveCollection(Collection obj, String fileName)
throws FileNotFoundException, IOException {
// Create a objectoutputstream
out = new ObjectOutputStream(new FileOutputStream(fileName));
// Write the collection object to file
out.writeObject(obj);
// Close the objectoutputstream
out.close();
* This method read a collection object from specified file.
* @return collection The collection we have read.
public Collection readCollection(String fileName)
throws FileNotFoundException, IOException, ClassNotFoundException {
// Create a objectinputstream
in = new ObjectInputStream(new FileInputStream(fileName));
// Asign the read object to a Collection "container"
Collection collection = (Collection) in.readObject();
// Close the objectinputstream
in.close();
return collection;
}The differens is that I don't catch any exceptions in those method writing and reading objects. Only throw exceptions.
Try it out and see if it helps... (last shot) ;)

CSS SSL Proxy - how can I write the original source address in http header
I'm replacing some BigIP's with CSS11500's that are configured to do front/backend ssl proxying in a one-armed configuration. The BigIP's write the original source IP address as a http header value when the traffic is sent to the application, and the application uses the IP to match against an application ACL. How can I do the same in the CSS.
thanks,
Brianhere is what you can insert with the SSL module :

How can I write to a Siemens S7-300 PLC tag from OPC Server.vbai page by using a Knob object ?
I am using NI OPC Server and I can read Siemens S7-300 PLC tags such as thermocouple values from the PLC. Additonally I can write manually a constant value to that tag by selecting it in the NI Distributed System Manager. And I can read the written value from NI Distributed System Manager or from NI OPC Server. But I can not write any value to the S7300 PLC tags such as by using a knob object at the NI Vision Builder AI Inpection (.vbai) page.
Any help is welcomed. Thanks in advance.
Attachments:
manual_writing_to_plc.png 298 KBThe tutorial at the following location explains how to use Vision Builder AI as a OPC server.
https://decibel.ni.com/content/docs/DOC-18647
http://www.ni.com/white-paper/13574/en
To allow VBAI to connect to an OPC Server (i.e. act as an OPC client), you need to purchase and install the DSC Run-time System.
Once installed, you can create an OPC I/O client using the Distributed System Manager, create variables bound to OPC tags, then create VBAI network variables that are bound to these variables.
Another possible technical solution to connect to OPC Servers supporting Data Access 2.0 is to use the datasocket API in a Run LabVIEW step.

How can I write relative path in File, ImageIcon objects
I have downloaded examples from
http://java.sun.com/docs/books/tutorial/uiswing/components/example-swing/index.html
but for some reason images are invisible until I write absolute paths?(I use windows) How can I write relative path in File, ImageIcon objects?Hello;
I've found a lot of complaints about this through the Forte forum as well as on Dejanews. I'm just curious as to whether any of you ended up finding a solution to this problem.
There was one posting about setting up the subdirectory as a URL rather than a String and then using that as the source of the ImageIcon ... but this didn't work for me.
Any help whatsoever would be appreciated.

Can you write javac in java Language
Hi,
is it possible to write java compiler in java language.Here's a compiler written in Java, it is part of an IDE I wrote:
Compiler.java: import java.io.*;
* Wrap up javac.
* The class exists to supply a single method - to compile a file
* and report status along with error/success messages
* Compilation (by javac) is carried out asynchronously using a
* background Thread. Status and any error messages are passed back to
* the calling object through a callback method.
public class Compiler implements Runnable
* Constructor.
* @param owner the <TT>JavacTool</TT> that has created this Compiler
public Compiler( CompilerListener owner )
myOwner = owner;
private CompilerListener myOwner;
* Compile a file using javac.
* This method will compile a Java source file and report both the
* status of the operation and any error strings produced.
* The method kicks off a separate Thread that actually carries out
* the compilation. Upon completion a the JavacTool is called back with
* a CompilerStatus object.
* @param filename the name of a file which <I>must</I> be in the same directory
* as the JavacTool was run from. this tool does not have tha capability
* of working across multiple directories.
public void compile( String fileToCompile )
filename = fileToCompile;
new Thread( this ).start();
private String filename;
* The method run by the separate Thread.
* It runs once for each filename passed to the Compiler object.
* It creates a new OS process to run "javac filename" externally
* and captures the error output from the real compiler into
* a String so that it can be returned to the calling code via
* a callback method (very similar in principle to an event)
public void run()
CompilerStatus returnValue = new CompilerStatus();
returnValue.outputString = new String();
try
Runtime r = Runtime.getRuntime();
Process p = r.exec( "javac " + filename );
InputStream is = p.getErrorStream();

while( line != null )
returnValue.outputString += (line + "\n");
line = rdr.readLine();
p.waitFor();
returnValue.exitValue = p.exitValue();
if( returnValue.exitValue == 0 )
returnValue.outputString = "Compilation successful\n\nNo errors\n";

e.printStackTrace();

}This is taken straight from my IDE; you'll have to adapt it slightly to make it into a seperate application -
How can i write a string into a specified pos of a file?
How can i write a string into a specified pos of a file without read all file into ram and write the whole file again?
for example:
the content of file is:
name=123
state=456
i want to modify the value of name with 789
(write to file without read all file into ram)
How can i do it? thank youtake this as an idea. it actually does what i decribed above. you sure need to make some modifications so it works for your special need. If you use it and add any valuable code to it or find any bugs, please let me know.

I have a new iMac (like this):
I am trying to connect the Drobo that I used to use with my Windows Computer. It has 4 drives @ 3TB each, and the whole drive is over half full, so I am not terribly interested in the cost that it would take to "back up" that whole disk pack. It took some shenanigans (reboots of both the drive and the computer; disconnections, and reconnections; fiddling around with MAC Disk Utility) to get it to show up in Finder at all. I still have issues with it unmounting and needing to remount it, but that's not my main issue.
THE REAL PROBLEM:
Though I can get the Drobo to show up in finder, and I can read from it, I can't write to it. Based on some earlier searching I tried this terminal command, which helped it to show up in finder, but didn't seem to affect it's being read-only:
new-host-3:~ davidholcomb$ getfileinfo /Volumes/Drobo
directory: "/Volumes/Drobo"
attributes: avbstclinmedz
created: 12/10/2012 19:06:46
modified: 09/11/2014 03:37:07
Looking at another thread (partition map check failed because no slices were found), which I wandered into because I was getting this error in Disk Utility upon running Verify Disk because I got a failure when I tried to "mount" the drive in Disk Utility:
This thread suggested I try a couple additional Terminal Commands, which I will post the results of here:

Can anyone help me with a next step to make this drive read/writeable?Turns out that the Drobo needs to be plugged straight into computer. I had it via hub. Though it has worked for the past couple weeks in this configuration, the new update pushed it over the edge, I guess. Plugged in directly and working fine.

Hi All,
powershell script Method required to read a value from registry and then taking the backup of that values in some text file.
For example the hive is
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\Path
and under path i need to take back up of values in some text file and then put some value in the registry after back is taken in text file.
Also how to read the text file values so that we can again write to registry hive back from the back up text file.
Your help is much appreciated.

Converting a class object back to a .class file
Hi,
How can i convert a class object back to a .class file ? Thanksany pointers on how to do it then ? i don't have
access to the native codeIf I have understood you correctly, you have native code that generates bytecode. Currently you load the class this bytecode represents right into the classloader, but you want to save it to disk as a .class file. Right?
If so, you just have to get hold of that bytecode before it "disappears" into the classloader, and save it to disk. How you can best do this depends on exactly how you communicate with that native code.
If I have misunderstood your problem (and that's not unlikely), please try to be clearer. -
Crystal Report XI: Can you write your query in SQL instead of using the GUI
Hello
In crystal report version XI, can you write your query in sqlplus and then use the crystal report designer to build your report instead of using the GUI . I would like to be able to go database and show sql query and open that query and make changes directly there, is that possible on this version, if yes is there a setting somewhere? Please let me know.
Thank you
alphaMoved to Database forum.
No you can no longer modify the SQL directly. Use a Command Object to enter the SQL directly.
Thank you
Don
