Urgent help!!! Server java and midlet
Hi,
I have write a simple java server that run on a pc.
This waits for socket connection. I also write a midlet that connect cia socket connection to my server. The connection is established and the server say wellcome to my midlet and on the cell screen the message appears. After the midlet answers to the server hello but the server doesn't receive anything, nothing... I insert a println but the server stay blocked on the read on the DataInputStream. But the midlet says "I have send the message!"+answer.
If someone say me that I can post the code I do it, but it's a bit long.
Help!!!!!!
Yes, to be sure data is really send, you'll need to call flush, preferably on server and client. You can do this after every complete block of data, so not nedded after every write.

Urgent help(xml, java and asp)
Hi all,
I,m new with XML and i have to convert a VB application that connects to an ASP using Microsoft XML and I need to know if I can connect from a java application to an ASP using XML for transfering the infornation.
In the ASP side it uses DOM, and I would like not to touch the ASP and create a new application with java and get rid of the VB applicationDrClap what I have in the VB side is this:

What I need to do is to change the VB part for a Java application and basicly, I don't know what Class of Java I have to use to connect to the ASP.
If you were so kind of giving me an example to do this I will appreciate it.

CRM Application Server Java and Portal components on same Java stack
Hi Team,
We are currently performing solution design and want some information on CRM install.
Want to know if there is any restriction for installing CRM Application Server Java and Portal components on same Java stack(With same SID). Also want to know if SAP WEB UIF 7.0 can work similar to that of Portal for CRM applications?
Any information around this would be appreciated.
ThanksDo You have any servlets or filters defined using annotations? Maybe one of these servlets/filters catches the '/login' request first. I have very similar solution and it works fine. Also, how do You check that the servlet under '/login' url pattern isn't invoked?

MarinaHi,
You are very lucky that I'm currently boored. You should never tag a question as urgent. It might be urgent to you, but not to us who answer. And you should also use code formatting when you post code (see the formatting tips, or use the code-button).
I made some changes to your Graph class. The most important thing is the abstract draw method that I added to the GeomFigur class.

Point p1, p2;
public Line(Color c, Point p1, Point p2) {
super(c);
this.p1 = new Point(p1);
this.p2 = new Point(p2);
public String toString() {
return "Line from " + p1 + " to " + p2;
public void move(Point dist) {
p1.move(dist.x, dist.y);
p2.move(dist.x, dist.y);

Help with Java and Regular Expression
Hello,
I have one line of Java and regular expression that I got from the web :
String[] opt;
opt = line.split("\\s+(?=([^\"]*\"[^\"]*\")*[^\"]*$)");
If "line" contains :
1 "Hello World"
this code would give me :
opt[0] : 1
opt[1] : "Hello World"
which is almost what I would like to do except for the double quotes. I wonder if someone could please help me change the regular expression so that it would return :
opt[0] : 1
opt[1] : Hello World
Thank you and Best Regards,
ChrisIt looks to me like this is a line from a space delimited file so you should use one of the free CSV parsers such as http://opencsv.sourceforge.net/ . These will handle the quotes properly even if a field actually contains a quote.

Need Help w/ Java and Mozilla on SuSE 8.2
I am completely and totally new to Linux. Until not very long ago the only computer I ever worked with was MS. I'm running SuSE 8.2 Professional.
I used (after much trial and error) the rpm program to remove Mozilla 1.2 (which is installed by default). This is a machine at home so I have root access and regular access. I downloaded Mozilla 1.3 and installed that without a problem. I download j2sdk 1.4.1.02 (I'm pretty sure those are the numbers). I followed the instruction on how to install java and it appears to have worked correctly. I don't know how to test but there is now a directory called j2sdk1.4.1_02 which has several files and directories inside of it (including jre). I also followed the instructions and installed the java web start program.
Anyway, I've searched the forum for information that would explain how to make mozilla work on website that use java. Most of what I read was greek to me. But there was one that said I should copy the libjavaplugin_osi.so file into the mozilla plugins directory. I did that and when I looked at the "about plugins" page (from Help in Mozilla), it showed a lot of java files. But when I go to any pages that are using java, the page starts to load and then closes. This happened on about 6 different pages (all different web sites). So I think something went wrong. A friend had told me I'm going to have to make a "symlink" (which I don't know how to do). But he's on vacation and won't be back for 2 weeks.
Can anyone help?
Here are the directories where everything is stored. Oh, by the way, when I installed mozilla, java and javaws, I did all of it from the root account. If that was wrong, tell me and I'll fix it.
mozilla is in:
/usr/local/mozilla/
java is in:
/usr/local/java/j2sdk1.4.1_02/
javaws is in:
/usr/local/java/javaws/
Again, as I'm sure you can tell, I'm lost, totally new to linux, mozilla and java. So if you can help, please explain as clearly as possible.
Thanks in advance.Your friend is correct, instead of copying the .so file you should have made a symbolic link. To do that, first remove "libjavaplugin_oji.so" from "/usr/local/mozilla/plugins"; it's on the way. Then create the symlink with the "ln -s <source> <destination>" command, with your configuration it should be something like:
ln -s /usr/local/java/j2sdk1.4.1_02/jre/plugin/i386/ns610/libjavaplugin_oji.so
/usr/local/mozilla/plugins/
(you need to be root to do that)
To set up web start in mozilla, it might be easiest to go to the demo page and try to launch one of the applications:
http://java.sun.com/products/javawebstart/demos-nojavascript.html
When the "what should mozilla do with this file" dialog pops up, click on the "Advanced" button and make Mozilla handle it with the javaws application. Optionally remove the cross in "Always ask before opening .." -
Urgent Help Regarding PDF and Word Document Downloading
Many Thanks Shaik for you humble help. Actually now what I did in the past 3 days,
I used Oracle Intermedia to store my PDF and Word Documents in the database using Oracle SQL Loader. Then I used PL/SQL Server Pages and Oracle Web Toolkit for the downloading of my documents.
Now the problem is I saved all my formatted documents in the databse and for retrieval I am using following code in my stored procedure
* Select BLOB Data
select blob_data into myblob from mytable where blob_name = name;
Setup headers which describes the content
owa_util.mime_header('text/html', FALSE);
htp.p('Content-Length: ' || dbms_lob.get_length(myblob));
owa_util.http_header_close;
Initiate Direct BLOB download
wpg_docload.download_file(myblob);
end;
The structure of the mytable table:
create table mytable
doc_id varchar2(128),
doc_name varchar2(128),
blob_data blob
But when it prompt the client to download the file actually it gives the junk file name like 'B104ea56' (which i understand is the address of the blob address). What I want is to show the "SAVE AS" download box with the proper document name which is stored in my field in the following way
1 SALES.PDF
2 PLANNING.PDF
3 MANUAL.DOC
4 STANDARD.TXT
If I set the MIME type for the file format than it automatically starts download the file to the client browser, that I do not want, It should ask the user to download with the proper document name.
Waiting consiously for your help
RegardsPresumedly you'd like those documents being accessiable by users as well, so they should be put on a web server, ftp or nfs sharing. You can just add the urls to those documents, or the directory they are in, into robot system as starting points and let robot run to collect them.

Hi, guys,
I am being involved in a project.My current task is to build an interface using java. This interface will obtain some information from a linux-based software called NistNet, which is done by C and has GUI as well. My question is, can I use this java-based interface to obtain some information that is typed in this NistNet'GUI? If I can, how can I do that?
Any hint available?
Thanks!You can bridge between Java and C using the "Java Native Interface" (JNI). There used to be a good tutorial on this site but it vanished for no apparent reason in some resent update, so try a websearch.

Need a little help understanding java and /etc/profile.d/***
A few days ago I installed jre-6u10-1 and jdk-6u10-1 via pacman on my desktop machine; for the web plugin.
The packages installed in /opt/java/...
I later installed jedit, via pacman. It runs fine as it (/usr/bin/jedit) is hardcoded to look for java in /opt/java/...
Today, I installed jedit (pacman -S jedit) on my laptop which did not have any java installed.
Pacman automatically installed openjdk6-jre-6u10-1 as a prerequisite.
Openjdk installs to /usr/lib/jvm/..., therefore jedit fails as /opt/java... is non-existent.
I suppose Sun's java and the opensource version are installed in different locations to keep from overwriting each other.
I could easily edit /usr/bin/jedit to point to the openjdk location and it would work.
But I'm a little uncertain of the following three files:
Sun's java installs /etc/profile.d/jre.sh and /etc/profile.d/jdk.sh
which do the following (respectively):
export PATH=$PATH:/opt/java/jre/bin
if [ ! -f /etc/profile.d/jdk.sh ]; then
export JAVA_HOME=/opt/java/jre
fi
and
export J2SDKDIR=/opt/java
export PATH=$PATH:/opt/java/bin
export JAVA_HOME=/opt/java
The opensource java package installs /etc/profile/openjdk6.sh
which does the following:
export J2SDKDIR=/usr/lib/jvm/java-1.6.0-openjdk
export J2REDIR=$J2SDKDIR/jre
export JAVAHOME=/usr/lib/jvm/java-1.6.0-openjdk
#export CLASSPATH="${CLASSPATH:+$CLASSPATH:}$J2SDKDIR/lib:$J2REDIR/lib"
So I am left with a few options:
1. edit /usr/bin/jedit to look in the opensource location
2. edit /usr/bin/jedit to use the $J2SDKDIR variable when looking for java
3. update the $PATH via /etc/profile.d/openjdk6.sh to include java's location
I think all three methods would work, but I have limited experience with java and would like some input as to which proposed solution is the best going forward.
What methods are other java apps using to find java?
Thanks
(edit: more descriptive title)
Last edited by cjpembo (2008-11-11 04:24:47)I think the best option would be to ask the maintainer to modify the jedit-bin file, and have it launch
$J2SDKDIR/bin/jre/java cp $CP -Djedit.home="/usr/share/jedit" -mx${JAVA_HEAP_SIZE}m org.gjt.sp.jedit.jEdit $@
That way, it should work with both java implementations (completely untested, btw.) -
*URGENT HELP REQUIRED* java.sql.SQLException: Invalid Oracle URL specifed
Hi all,
In the middle of the last week for my final year project and having to convert to an Oracle database due to compatibility problems with university Tomcat Server and MS Access. I'm having trouble connecting to the Oracle database and would appreciate some help please.
Running on Windows 98 in the lab here, and the Oracle 9i, release 9.2.0.2.0, J2SDK1.4.0, Classes12.zip installed OK.

Class.forName("oracle.jdbc.driver.OracleDriver");
cardSaleConnexion = DriverManager.getConnection("jdbc:oracle:[email protected]:1521:sid","user_name","pwdt");
System.out.println("Connection Successful ");
And I'm getting the following error when calling the constructor in a driver program:

I NEED URGENT HELP IN JDEVELOPER AND OID
Hello.
Please I need to know about some tutorial that this explains step to step a code in JDeveloper that obtains and send data of the Oracle Internet Directory (OID).
The only code source that I found is the Grocery Store but I need to know more, from the beginning.
Please I need HELP, it is really URGENT.Hi,
Try http://java.sun.com/products/jndi/reference/codesamples/index.html. I think Oracle is not using their own JNDI wrapper any more and just using the regular API.
Good luck, Hernando

daminiYou got some good advice from Java_Jay.
Here is a snippet I keep handy for console input and output. It doesn't do your home work but gives you a working example of getting numbers from stdin:
import java.io.*;
public class DemoKeyboardInput {
public static void main(String[] args) throws IOException {
// open keyboard for input (call it 'stdin')
BufferedReader stdin = new BufferedReader(new InputStreamReader(
System.in), 1);
// get input from the keyboard
System.out.print("Please enter your name: ");
String name = stdin.readLine();
System.out.print("Please enter your age: ");
String s1 = stdin.readLine();
System.out.print("Please enter the radius of a circle: ");
String s2 = stdin.readLine();
// perform conversions on input strings
int age = Integer.parseInt(s1); // string to int
double radius = Double.parseDouble(s2); // string to double
// operate on data
age++; // increment age
double area = Math.PI * radius * radius; // compute circle area
// output results
System.out.println("Hello " + name);
System.out.println("On your next birthday, you will be " + age
+ " years old");
System.out.println("Area of circle is " + area);
