Parallel Port access using Java

hello guys.. Please Solve my Problem..
I have to access motor through pc using Parallel Port. I want to know how to program in java to access Parallel Port. So How can i code to access the any Port of Parallel Port. Please Guide me in this..
I have tried using parport (code given below )---------------->but it gives error hs_err_pid2172.log (error explanation given at last ). Please tell me what is the problem or if u have any other alternative to access Parallel Port
//===============================================================================
//code :
package parport;
public class ParallelPort
private int portBase;
public ParallelPort(int portBase)
this.portBase = portBase;
public int read()
return ParallelPort.readOneByte(this.portBase+1);
public void write(int oneByte)
ParallelPort.writeOneByte(this.portBase, oneByte);
public static native int readOneByte(int address);
public static native void writeOneByte(int address, int oneByte);
static
System.loadLibrary("parport");
import parport.ParallelPort;
class SimpleIO {
public static void main ( String []args )
ParallelPort lpt1 = new ParallelPort(0x378);
lpt1.write(240);

I alread have tried use RXTX library..

Parallel port access problem

Hi all!
I'm trying to communicate with parallel port using the commapi version 2. Unfortunately, the api doesn't accept any other mode than SPP mode that is read-only. When I try to change the parallel port mode, I got an UnsupportedCommOperationException. I'm working with windows xp.
Does anybody have an idea?
Thanks!
Thiago

PC parallel port access with XP

I recently got In Port and Out Port working on XP.
I searched the ni site for AccessHW. The CVI Run Time Engine has to be
version 5.510 or earlier. I checked the version number of one file, i.e.
cvirte.dll to verify.
I directed the installer to install accesshw to the directory where the new
In Port and Out Port and the rest of the new parallel port .vis were going
to be, i.e. Labview\Labview 6\vi.lib\platform.
I downloaded parallel.zip from ni.com and moved the parallelnt.llb file to
this same directory. Parallelnt.llb has a number of parallel port vis, not
just replacements for In Port and Out Port. I replaced the In Port.vi and
Out Port.vis in the diagrams I was trying to make work with the new .vis.
So, on this XP machine, with
a monitor program, parmon.exe, running to
display the bits on the parallel port, Labview can be seen to be using the
new parallel port .vis, and, bits on the port are changing.

I wonder if there's a reason why there's a javax.comm 3 series for *nix, but not for windows. Hmmm.

Parallel port programming in java

Help needed urgent please ( parallel port access in linux)

hi all, i am trying to read and write data to /from the parallel port , i am running IBM j9 vm on linux.under /dev there are lp0..lp3 parport0..parport3, and port devices , i dont know which one to use , i have tried all , they all return with an ioexception saying "cannot find the file" except for port device which does not generate any error but it does not return what i have written on it ,
any help would be much appreciated.
i am using fileoutputstream and printwriter calsses .
i dont want to use javax.comm api cause i think its incompatible with ibms visual age micro edition ( the one i am using ) so i would prefer something that works with my IDE .
thanks

However, there is an on-going OpenSource version called "RXTX" (http://jarvi.ezlink.com/rxtx/) that works quite well. Be sure to read all the documentation that comes with it, as you'll need to set some permissions on the ports you want to use.

Help...create database(access) using java

i had developed an java application that capture packet using Jpcap but i dont know how to keep the packet captured into database(access).i can save the packet captured in text file but not in database(access).i already had the database conectivity but i don't know how to insert the packet caputred in the table in access, is it using sql statement like INSERT INTO? or else?i realy don't know.can someone help me....?

i can save the packet captured in to text file but not in database(access).I guess that you wish to get a databse file with your data, not a simple insert sql question.
1. commercial solution: HXTT Access(http://www.hxtt.com/access.html), which supports create database, create table sql, and batch insert data from any JDBC driver.
2. free solution: jdbc-odbc bridge and dsn-less jdbc url, you need to prepare a blank mdb file with blank table, then copy that blank mdb file into new mdb file, then repeat insert sql for that new mdb file.

Hello,
I can open a parallel port (LPT1) using java comm api i,e javax.comm.
but problem in sending data to parallel port,
I choose the appropriate port(LPT1), it is in bi-directional mode according to BIOS configuration.
but according to the java program the mode is SSP.
when i write data to parallel port the volt-meter give a reading of high state for all data pin (pin1 to 9) i,e the parallel port doesnot change state. I am using windows XP.
What is the solution?

try it on Open Solaris 10 or Linux platform.
also just try using the new FileWriter("LPT1").write("Hello");
on windows platform

Java and parallel port

I don't know if this is forum I should ask this question but I didn't find any corresponding
to java and ports control.
I'm using Aurox 11.0 linux.
I wonder if I could control each output (DATA pin) of parallel port separately in
Java Communications API?. I can control outputs in Java with JNI but I need to run
program as root. If I would want to create applet which would use parallel port
I would have to create server with which this applet would communicate (Limitations of
applets). But this server would have to run as root. It would affect security of system.

Because of C++ ioperm function. This function requires root privileges. I have JNI Java
program which can control outputs of parallel port on the level of one byte (write
whole byte - all DATA outputs) and C++ program which can control outputs of port separately (control of each pin) and both are based on ioperm function. Both require
root privileges. So my question is: can I control each output pin separately with Java Communications API?. Maybe if I used wholly Java code I could access port with user privileges?.

Parallel port use Lookout

Does anybody know how to read/write through the parallel port with Lookout 5.0? Is there any example code for this?

Hi,
It is possible to send bytes to the parallel port using the ASCII object within Lookout. However, it is presently not possible to control the state of the individual bits on the parallel port with Lookout.
If you need to control the individual bits on a parallel port, consider using LabVIEW. It is much more powerful when programming serial and parallel ports.

Executing Microsoft access macros using java

Hi Everyone,
I hava an application in microsoft access,in which many macros which extract data are there.I want to know is there anyway that I can execute the macro written in microsoft access using java.
Can anyone please answer the above.

I am rather certain that that is not possible via the ODBC driver and thus not possible via JDBC.
There is certainly an OS API that will allow that but accessing those is not a standard part of the Java API so it would require a JNI solution (yours or someone else's) or an application that allows that access.

Labview and parallel port

I have installed Labview 2010 32 bit in windows xp, but i cannot find "deviceand interface" in measurement and automation
can anyone help in this regards.
Do i need driver to access parallel port in labview?
thank you

It's right under Data Neighborhood in My System. Click the + next to My System to open the choices under it. It should be very easy to find unless your MAX has a big problem.
No, you don't need drivers to communicate with the parallel port.

Ms Acces using Java

Hi All
I have one doubt.
I want to know the primary keys of a table in ms access using java.The same code is working in oracle,db2.
i wrote this:
import java.sql.*;
public class Java1{
public static void main(String args[]){
try {
Connection con = null;
ResultSet rs = null;
PreparedStatement psmt = null;
Statement st = null;
String dataSourceName = "MsAccess";
String dbURL = "jdbc:odbc:" + dataSourceName;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection(dbURL, "","");
java.sql.DatabaseMetaData dbmd = con.getMetaData();
String str = "";
System.out.println("primary keys");
rs=dbmd.getPrimaryKeys"D:\\LAKSHMI\\MSACCESS\\db1",null,"DIVISION");     if (rs != null) {
     while (rs.next()) {
     str= str+"-"+rs.getString(4);
     System.out.println(str);
}catch(Exception e) {
e.printStackTrace();
I am getting this exception:

java.sql.SQLException: [Microsoft][ODBC Driver
Manager] Driver does not support this functionThere you have it. You're doing something Access doesn't support.
Oracle is much more advanced than Access. If you want to use both you'll either have to write code against the least common denominator (which is Access), or you split the code into one Oracle part and one Access part.

Problem storing date in MS Access using JSP

Hi all,
Can anyone please help me storing date in MS Access using Java i am getting errors. I think it is probably because MS Access take "date/month". I am entering a string with date and month example
1st October as "0110". I don't know how to enter a date in MS Access.
