Client Side Programs?
Hi Guys. I want to know what are the Softwares needed in client side (End User) ?Does JBoss Needed at Client Side for J2EE application?
it depends entirely on how you want the "end user" to interact with your application. if it's an rmi api, the end user will need to include some jboss jars. if it's a webservice or a web site, then the end user will not need any jboss specific jars.

Can php pass info to a java client-side program?
hi!
can a php script on a remote server (activated thru command line or whatever) pass data over the internet to a java client-side program? if so, how?
thanks!if it is listening to a known port, how would the data be passed?
thanks!
Not unless the Java program is listening on a known
port.

Error running a client side program through the worklist app
I am trying to run a simple client side application (actually just a command script
that does a pause). I construct a send xml to client with a "call-program" message
with attributes of name="c:\testscript" and mode of async.
It appears that I need to register the program - how do I do this?

A complete uninstall and reinstall on a Windows computer requires you to follow specific instructions in a support document, while on a Mac, I have read you just have to reinstall over the old one.
I'm not sure if installing/updating to iTunes 11 would be the same on Windows or not, but since you report using a Mac, then it is probably a mute point. Good luck. -
Run a client-side program when using web-enabled forms(host command)
I am trying to run a local program on my windows machine when i press a button on the oracle web form SCAN[Host('C:\scktscan.exe')]. It trys to execute the program on the server machine and not the client machine. The button will work when forms are run in client-server mode. How can i get the button to access a program on the client machine when the forms are run on the web?
In order to execute a program at the client pc, you must implement a java bean.
Have a look at the demos extension pack 1 (http://otn.oracle.com/sample_code/products/forms/content.html)
It explains also how to implement this in your own application. -
Client-Server side programing problem
I designed a client-server program as seen below basis on serversocket and thread
I use serversocket for making a host connection than people connect this socket via applet that i designed then they transffer data with socket.getInputStream() and socket.getOutputStream but it always happening between client and server how can i make theese streams transfer between clients is something like that possible if it is how?
I couldnt send my hole java code because its too long and i wish i could explain my problem
public void run()
try
servsocket = new ServerSocket(port);
jTextArea1.append("Kullanici Girisi Bekleniyor.\n");
catch(IOException e)
jTextArea1.append("Sunucu Uzerinde Socket Acilamadi.\n");
while(calisiyor) //calisiyor variable is a boolean variable for checking if server is running
try
Socket sock = servsocket.accept();
background = new techsupportbackground(this,sock);
background.start();
catch(Exception e)
printstring("Hata:"+e);
break;
this is the techsupportbackground classes run method it extends from thread
public void run()
if(!servicesetup()) return;
support.printstring("Baglanti saglandi,kullanici basariyla giris yapti.");
setPriority(MIN_PRIORITY);
String sonmesaj = "";

String mesaj = readinputline();
if(mesaj == null) break;
if (!sonmesaj.equals(mesaj))
support.printstring(username+"->"+mesaj);
sonmesaj = mesaj;

client.printstring("Baglanti Saglanamadi:");
return;
catch(Exception e)
client.printstring("Baglanti Saglanamadi");

How can i load file into database from client-side to server-side
i want to upload file from client-side to server-side, i use the following code to load blob into database.
if the file is in the server-side, it can work, but if it in the client-side, it said that the system cannot find the file. i think it only will search the file is in the server-side or not, it will not search the client-side.
how can i solve it without upload the file to the server first, then load it into database??
try
ResultSet rset = null;
PreparedStatement pstmt =
conn.prepareStatement ("insert into docs values (? , EMPTY_BLOB())");
pstmt.setInt (1, docId);
pstmt.execute ();
// Open the destination blob:
pstmt.setInt (1, docId);
rset = pstmt.executeQuery (
"SELECT content FROM docs WHERE id = ? FOR UPDATE");
BLOB dest_lob = null;
if (rset.next()) {
dest_lob = ((OracleResultSet)rset).getBLOB (1);
// Declare a file handler for the input file
File binaryFile = new File (fileName);
FileInputStream istream = new FileInputStream (binaryFile);
// Create an OutputStram object to write the BLOB as a stream
OutputStream ostream = dest_lob.getBinaryOutputStream();
// Create a tempory buffer
byte[] buffer = new byte[1024];
int length = 0;
// Use the read() method to read the file to the byte
// array buffer, then use the write() method to write it to
// the BLOB.
while ((length = istream.read(buffer)) != -1)
ostream.write(buffer, 0, length);
pstmt.close();
// Close all streams and file handles:
istream.close();
ostream.flush();
ostream.close();
//dest_lob.close();
// Commit the transaction:
conn.commit();
conn.close();
} catch (SQLException e) {Hi,
Without some more details of the configuration, its difficult to know
what's happening here. For example, what do you mean by client side
and server side, and where are you running the upload Java application?
If you always run the application on the database server system, but can't
open the file on a different machine, then it sounds like a file protection
problem that isn't really connected with the database at all. That is to
say, if the new FileInputStream (binaryFile) statement fails, then its not
really a database problem, but a file protection issue. On the other hand,
I can't explain what's happening if you run the program on the same machine
as the document file (client machine), but you can't write the data to the
server, assuming the JDBC connection string is set correctly to connect to
the appropriate database server.
If you can provide some more information, we'll try to help.

Changes in server side java file not reflecting in Client side java code?
Hi friends,
iam using eclipse IDE, JBoss server, SWING GUI and Oracle DB
( looks like : SWINGGUI (Client) <--> EJB's (serverside) <---oracle )
my problem is , when i make change in server side bean file, that changes are not reflecting in GUI programs.
(for ex: iam adding settr and getter for a field and using that in GUI program. but its not identifying that setter or getter).
please tell me what should i do for every change done to server side program, that should reflect / available to GUI?my problem is , when i make change in server side bean file, that changes are not reflecting in GUI programs.
(for ex: iam adding settr and getter for a field and using that in GUI program. but its not identifying that setter or getter).what do you mean it's not "identifying" the methods?
you have to call those methods you know
are you getting NoSuchMethodError?
please tell me what should i do for every change done to server side program, that should reflect / available to GUI?you haven't posted any code or error messages that might help us debug -
How To Update A Table View From Client Side !!!!
Hi I would like to update a table view from the Client Side. So that the user can keep updating the relevent data on the client and when they have finally finished they can press Save so the entire page is then sent to the Server.
Does anyone know how to do this, I guess u have to use the EPCM, I have just started on it and would really appreciate some Help.
Thanks,
Emmanuel.This is what I found :-
There are a couple of ways to approach this.
1) load the excel spreadsheet into the database "as is". You can use interMedia
text to convert the .xls file into a .htm file (HTML) or use iFS (see
http://technet.oracle.com/
for
more info on that) to parse it as well. InterMedia text will convert your XLS
spreadsheet into a big HTML table (easy to parse out what you need at that
point)
2) Using OLE automation, a program you write can interact with Excel, request
data from a spreadsheet, and insert it. Oracle Forms is capable of doing this
for example as is other languages environments. In this fashion, you can remove
the "manual" and "sqlldr" parts -- your program can automatically insert the
data.
3) You can write a VB script that uses ODBC or Oracle Objects for OLE (OO4O) in
Excel. This VB script would be able to put selected data from the spreadsheet
into the database. We would recommend OO4O. It provides an In-Process COM
Automation Server that provides a set of COM Automation interfaces/objects for
connecting to Oracle database servers, executing queries and managing the
results. OO4O is available from
http://technet.oracle.com -
Merging randomly-named XML data file on client-side with pdf designed in Livecycle 7.0 (and addition
Okay, as a heads up I work for a financial institution and we are converting our legacy "jetforms" to pdf format. I have in my staff for the project, 2 code developers and myself- a form designer. We have currently spent 2 months in trial and error attempting to resolve this problem, please let us know anything you can have. All client-side (internal) machines are running Windows XP and Adobe Reader 7.0.7
The software we use as a financial institution allows our users to export a customer's data file onto their machine which is then renamed to include the member's account number and first and last name for our staff to determine which data file they need more accurately. In legacy jetforms, we have developed a program that pushes the data from the customers file that they select, into the jetform that they want to open and the matching fields in the data file fill in the fields of the jetform. Clean and simple.
Now, i have hit nothing but frustration when attempting to perform the same process with pdfs using a form designed in livecycle designer 7. First, i see no obvious command for opening a pdf and importing a data file using a command line, like pdfmerge or something of the sort in which an xml data file can be specified and a pdf can be specified. I saw something like it using an fdf format and attempted to do this but apparently reader cannot import the data into the pdf that was designed adobe livecycle 7. All i have been seeing is database connections and using javascript inside the form to populate fields based on these database connections, etc. etc. or doing a manual file>import data>etc. which we don't want to have our staff do. We do not have reader extensions enabled, simply because i cannot get an adobe representative to call me and discuss pricing nor see any estimated pricing chart around. I don't know if reader extensions are necessary for this or not but i'm becoming very very frustrated with it.
We don't want a complex server-side data connection binding with dynamic input. No, we just want it where our developers can say "if this data file is selected, and this pdf form is selected run this command" which would be a simple pdfmerge type solution. Is this possible or do i need to stay with jetforms until our software the billion dollar financial institution uses does form building inside its own application? I don't want to fight about who is better, what version to use, etc. I just want the straight up honest truth. If you need to know the pricing that the reader extensions would have to go by, assume there will be 500 client computers that will need to use it.From your post it sounds like you are Central Pro (a product for which I am by no means an expert), but you say you want to upgrade to a newer product from your "legacy" one. Is there a reason for this? Have your requirements change so that it no longer fits them? Central is still in the current Adobe roster and as far as I know there is no plans to get rid of it any time soon, so if it does everything you want I don't see why you would want to change.
There is no product in the LiveCycle suite that merges xml data into a form from the command line. LiveCycle (with the exception of Designer) is a suite of server products, so the closest you would come is LiveCycle Forms (merge the xml and create a fillable PDF) or LiveCycle Print (merge the xml and print the form).
Hope this helps somewhat.

Reporting Services Client-Side Printing
All my BI users should be able to print SSRS directly from their Local PC. Right now they do not have administrative rights on their PCs. How do I install the print- client SSRS files on the client machines. Also, what and where are the
files I need to install in order to enable client-side printing. I am using SSRS 2012 SharePoint integrated mode.Check out this article...
http://www.kodyaz.com/articles/client-side-printing-silent-deployment-of-rsclientPrint.aspx
The same concept applies no matter which version of SSRS you are dealing with. You just need to find the CAB file. For SSRS 2008 R2 it is in:

hello everybody,
I need to know how I can execute a javascript in a custom validator Tag without specify it in the Tag but in the ValidatorTag.java and the ValidatorTag.tld. My problem is to render comprehensible JSF for a non-coder so I must code all the java program outside the JSF code as the non coder program just the JSF Tag.
thanks a lot for your answersYou should have look at chapter 9 of the Core JSF e-Book. There is an example with client side validation of a spin field (page 396-400)

Is XML-SQL Utility for Java run on Client Side?
A question about the XML-SQL Utility for Java
When a client program connect to a Oracle database (the clinet program and Oracle DB is run on two different machine. Oracle 8i is used) and use the oracle.xml.sql.query.OracleXMLQuery Class (form the XSU) to generate XML by given a SQL query. I want to know the transforation process is execute in the Clinet side or the database?
Is there any method that i can retrieve the XML directly from the database rather then doing the transformation form the Client side?Set JDK_HOME to the directory where you install your JDK (Java Development Kit).
So instance, I've install JDK1.1.8 on my
C drive so
set JDK_HOME=c:\jdk1.1.8;c:\jdk1.1.8\bin -
Java Stored Procedure / connection JDBC / Server Side / Client Side
Hi,
I would like to know if we can know at the runtime with a JDBC api if the stored procedure is running in client side or in server side ?
THANKSYou wrote
"Java stored procedures -- by definition - are stored in the 8i rdbms. !!"
From the Oracle8i Java Stored Procedures Developer's Guide
Release 8.1.5
A64686-01
"If you create Java class files on the client side, you can use loadjava to upload them into the RDBMS. Alternatively, you can upload Java source files and let the Aurora JVM compile them. In most cases, it is best to compile and debug programs on the client side, then upload the class files for final testing within the RDBMS"
This means that you can create shared classes that are used on both the client and server side. The source does not need to reside within the server (according to their documentation). Please also note the following from the Oracle8i JDBC Developer's Guide and Reference Release 8.1.5 A64685-01 for using the getConnection() method on the server:
"If you connect to the database with the DriverManager.getConnection() method, then use the connect string jdbc:oracle:kprb:. For example:
DriverManager.getConnection("jdbc:oracle:kprb:");
Note that you could include a user name and password in the string, but because you are connecting from the server, they would be ignored."
So if you're coding a shared class that is to run on both the client and server side, you might do something like this:
Connection conn =
DriverManager.getConnection(
System.getProperty("oracle.server.version") == null
? "jdbc:oracle:thin:@hostname:1521:ORCL"
: "jdbc:oracle:kprb:"),
"youruserid","yourpassword");
As stated earlier, the userid and password are supposedly ignored for server connections retrieved in this manner. I haven't tried this yet, but it is documented by Oracle.

? "jdbc:oracle:thin:@hostname:1521:ORCL"
: "jdbc:oracle:kprb:"),
"youruserid","yourpassword");
As stated earlier, the userid and password are supposedly ignored for server connections retrieved in this manner. I haven't tried this yet, but it is documented by Oracle.

File transfer, read write through sockets in client server programming java
Hello All, need help again.
I am trying to create a Client server program, where, the Client first sends a file to Server, on accepting the file, the server generates another file(probably xml), send it to the client as a response, the client read the response xml, parse it and display some data. now I am successful sending the file to the server, but could not figure out how the server can create and send a xml file and send it to the client as response, please help. below are my codes for client and server

Could you please point where am I doing the stupid mistake, client to server is working properly, but the opposite direction is not.
