Problem with java communication api for gsm modem port

Hi,every body
    Am using gsm modem in my project previously my linux is 32bit with 32 bit jvm of sun that time there was no problem at the time of working with gsm modem port .But now am using 64bit linux then 32bit files are not supporting to communicate with gsm modem port .How can i get java communication api for unix 64bit ,64bit jvm of sun.please any body help me ...i am searching in sun/oracle also for downloading java communication files of 64bit jvm but i didn't get the link... i need bellow java communication api files.
       ex:1)libLinuxSerialParallel.so
            2)javax.comm.properties
            3)comm.jar

Problem with Java Communication API

hi
I installed the Java Communication API on win32 platform (as per the guidelines)
Now when I try to run the sample program 'Blackbox' for the serial port, I get an error (in fact an exception is generated inside main function in BlackBox.class file)
I tried the SimpleRead.java example but that too generated the same exception
Can anybody help me out.... I am a novice with Java Comm API

I tried running the sample BlackBox program provided for serial port and now it says
No Serial Ports Found!
I verified that both comm.jar and javax.comm.properties are in the <JDK>\lib directory.
Actually, I am using netBeans IDE 1.4 and I used the C:\J2SDK folder installed with netBeans for the Java Communicaion API
plz help.

Having problem with Java Communication API

I am using this code to list the port that i have but it does not return any thing. when i compile and run nothing is printed out. i think either its not going in while loop but if i remove while loop it returns NULL. so i think its not recognizing any PORTS. i want to detect a modem port as i want to make a voice mail software. I am jsut starting by listing, opening and listening to the ports. Please help me ASAP. Thank you.
import javax.comm.*;
import java.util.*;
public class PortLister {
public static void main(String[] args) {
Enumeration e = CommPortIdentifier.getPortIdentifiers();
while (e.hasMoreElements()) {
System.out.println((CommPortIdentifier) e.nextElement());
}

Go back where you downloaded the API and read the FAQ. I think it's the question number 2.

About Java Communication API for Windows

hi
I'm studying Serial Communication in university.
I'd like to know the reason why we can't downlaod Java Communication API for Windows.
I confirmed Comm for Linux and Soralis, but I can't find Comm for Win.
Please tell me the reason if someone know.

For no particular reason Sun stopped supporting the windows version
of that package. I use rxtx which happens to allow for much faster
communication too.
The interface is identical to Sun's version, just the package differs: "gnu.io".
kind regards,
Jos

Problems with Java Scripting API

Hello Everyone!
Guys, I need help with Java scripting API. A problem is that I cannot understand how can I operate Java Object's fields and methods from the script language. I have chosen embedded javascript to work with. And I can get the fields and methods of in-box java classes (such as ArrayList for example), but I cannot work with methods and fields from my own classes!
Here is an example:
public class ScriptingExample {
    class MyClass {
        int myfield = 5;
        int getInt() {return 7;}
    public void runExample() {
        ScriptEngineManager mgr = new ScriptEngineManager();
        List<ScriptEngineFactory> factories = mgr.getEngineFactories();
        ScriptEngineManager factory = new ScriptEngineManager();
        ScriptEngine engine = factory.getEngineByName("JavaScript");
        MyClass mc = new MyClass();
        try{
            engine.put("mc", mc);
            engine.eval("print(mc.myfield); print(mc.getInt())"); // or engine.eval("print(mc.myfield)");
        } catch (Exception e) {e.printStackTrace();}
} If I run the code with the commented part it prints "undefined" instead of "5".
If I run the code as it is it prints error instead of "7":
undefinedjavax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: TypeError: Cannot find function getInt. (<Unknown source>#1) in <Unknown source> at line number 1

How can I fix it?

Guys,
please let me raise this topic because several new questions emerged.
(1) How can I get all the variables created inside my engine?
There are two kinds of variables: first kind is Java obejcts put inside the engine and second kind is the variables created in my script, such as 'var a = 4;'. How can I list all the variables of that two kinds?
(2) Is there is a way to make 'import static' to the engine? I dont want to write MyClass.MyEnum.MyEnumItem every time. Also, I cannot put the whole enum into the engine with engine.put("MyEnum", MyEnum); I can put only enum items separately: engine.put("MyEnum", MyEnum.EnumItemA);. Thats why I ask about static import.
(3) How can I cast engine variables back to java variables inside my java code?
Here is my example:
package mypackage;
import java.util.ArrayList;
import java.util.List;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineFactory;
import javax.script.ScriptEngineManager;
public class Main
     public static void main(String[] args) throws Exception
          ScriptEngineManager mgr = new ScriptEngineManager();
          List<ScriptEngineFactory> factories = mgr.getEngineFactories();
          ScriptEngineManager factory = new ScriptEngineManager();
          ScriptEngine engine = factory.getEngineByName("JavaScript");
          ArrayList<Double> myList = new ArrayList<Double>();
          myList.add(5.0);
          engine.put("MyList", myList);
          engine.eval("MyVar = MyList.get(0);");
          System.out.println((Double)engine.get("MyVar"));
}The result is:
Exception in thread "main" java.lang.ClassCastException: sun.org.mozilla.javascript.internal.NativeJavaObject cannot be cast to java.lang.Double
+     at mypackage.Main.main(Main.java:28)+
Is it possible to retrieve my Double java object from the engine?

Java communication api for windows 64 bit

Hi,
I need communication api for windows 64 bit. Are these api's in developement?
Thanks,
Andrea Todeschini

If you use version 2.0 of the rxtx library then it provides a complete implementation of the javax.comm package.
Version 2.1 does not (its in the gnu.io namespace)

Problem with Java Print API ( awt ) : Migrated from 1.1 to 1.4

We had migrated an application ( applet based) from Java 1.1.8 to java 1.4.
We use the java.awt.print apis for printing data from our applications.
There is difference in print quality after the migration. For e.g. if the data frame had a scroll bar when taken print out, the scroll bar was not visible in java1.1 version application but is being printed with java1.4 version.
We are unable to find the cause of this problem. Any help in this regard would be of great help.
Thanks in advance.

Hi,
thanks, this solved the problem.
Thank you.

Problem with java logging API

Hi there
It`s the first time I`m using (I have to use) the standard java logging API.
My need is to integrate it in an existing web-application based on struts.
So my first step was to include the following code into an Struts Action-class:
FileHandler file = new FileHandler("/pathToLogFile/myLogFile.log",true);
file.setFormatter(new SimpleFormatter());
logger.info("create info");
By intention is to have exactly one log-file for the whole application, but indeed I'm getting multiple log-files, even for each request of one and the same Action/Servlet class, like
myLogFile.log
myLogFile.log.1
myLogFile.log.2
myLogFile.log.3
Why does using append=true not work in the constructor of "FileHandler"
Do I have to close the FileHandler each time I've used it?
Is this a known issue?
Thanks for any responds!

@ Stone.li
First, thanks for your answer.
perhaps my question was quite confusing .... but my need is just
to establish the logging API in an existing Web-Application and to have exactly one log-file for the whole application. This means I would have to provide in each servlet a FileHandler referencing to the log-file. I thought it would be part of the job of the logging API to synchronise this file access.

More problems with java query API - getExcerpt fails

If I write my code this way, everything works:
mySearchRequest.setQuery(new oracle.ultrasearch.query.Contains(searchString, metadata));
But if I do this, Document.getExcerpt() starts returning null for the same search hits:
mySearchRequest.setQuery(
new oracle.ultrasearch.query.And(
new oracle.ultrasearch.query.Contains(searchString, metadata),
new oracle.ultrasearch.query.From(metadata.getGroup(groupToSearch))
Does anybody know how to make this work? I need to limit my searches by groups so that I don't have to create a new UltraSearch Instance for every single web site that has to be crawled (I have several).
Troy

Well, I finally discovered he solution on my own, by reverse-engineering Oracle's own search.jsp (which does not use Oracle's custom tag library, btw) (probably because same doesn't really work, or at least it doesn't what's in the documentation doesn't work) (which isn't surprising).
You have to do the "From" part of the query as an "attribute filter".
oracle.ultrasearch.query.Query searchQuery=
new oracle.ultrasearch.query.Contains(searchString, metadata);
oracle.ultrasearch.query.Query attrQuery=
new oracle.ultrasearch.query.From(metadata.getGroup(groupToSearch));
oracle.ultrasearch.query.Request searchRequest=new oracle.ultrasearch.query.Request();
searchRequest.setQuery(searchQuery);
searchRequest.setFilter (attrQuery);
Maybe that will do somebody some good somewhere...

[End of TNS data channel] with Java SDO API (JDBC thin 9.0.1.2.1)

Hello folks,
Environment:
Win2K, 1.2GHz Intel, 500MB RAM, Oracle 9i, Oracle JDBC Thin (9.0.1.2.1), JDK1.3
Our data in the DB is 2-D. It consists of SDO LineString geometries. We use SRID = 8307.
I run into this problem with Java SDO API. I got this exception: "Io exception: End of TNS data channel"
when I try to execute query that uses the SDO_RELATE function:
SELECT e.shape
FROM edge e
WHERE SDO_RELATE(e.shape,
mdsys.sdo_geometry( 2003, 8307, NULL,
mdsys.sdo_elem_info_array(1,1003,1),
mdsys.sdo_ordinate_array(-125.8,49.9,-125.6,49.9,-125.6,50.0,-125.8,50.0,-125.8,49.9) ),
'mask=ANYINTERACT querytype=WINDOW') = 'TRUE'
If I use SDO_FILTER instead of SDO_RELATE it works!
Here is how I execute the query in Java:
public int executeSpatialQuery(OracleConnection conn, String spatialQuery) throws Exception
int numberOfGeometries = 0;
conn.setDefaultRowPrefetch(1000);
Statement ps = conn.createStatement();
ResultSet rs = ps.executeQuery(spatialQuery);
while (rs.next()) {
numberOfGeometries++;
rs.close();
ps.close();
return numberOfGeometries;
Note: I was playing with the "conn.setDefaultRowPrefetch(n)" method hoping that there might be something to do with that but with no success.
Any help will be much appreciated. Thank you.

Hello folks,
Here is what I've done:
1. Created a "mini" Realtional model (modelB) which mimics exactly our existing "big" Realtional model (modelA). The tables, sequences, indices, etc. in modelB have been created in exactly the same fashion we'd created the corresponding entities in modelA. The only difference is that I preceeded the entities in our test modelB with "TEST_".
2. Populated the modelB with 1298 Lakes (3993 edges in total) in exatly the same fashion we use to populate our modelA - using a Data Loader based on Java SDO API.
3. Indexed the test modelB in exactly the same fashion as modelA.
4. Ran the query:
SELECT e.shape FROM test_edge e WHERE SDO_RELATE(e.shape,
mdsys.sdo_geometry(
2003,
8307,
NULL,
mdsys.sdo_elem_info_array(1,1003,1),
mdsys.sdo_ordinate_array(

-123.80833332065798,48.58352678668598
), 'mask=ANYINTERACT querytype=WINDOW'
) = 'TRUE'
in SQL*PLUS and it worked fine (retrieved a bunch of geometries)!
Ran the same query in the Daniel Geringer's OraTest utility and it worked this time and returned:
TIME : 1.222 seconds, TOTAL FETCH TIME 267 ROWS
Ran the query with our JCS Query Plug-In and it worked fine!

it SUCCESSFULLY returns the related geometries!
So, what can we make of all this? We know that there exists a model for which the SDO_RELATE works via the Java SDO API. This model is a subset (w.r.t. the data set) of our original model in which we detected the "TNS end of communication channel problem". The environment we used for these tests is exactly the same: JDBC Thin driver (version 9.0.1.0.0), Oracle9i Enterprise Edition (Release 9.0.1.2.1 - Production).
One can think that the problem lies in the Oracle Object-Realational or Oracle Spatial but the fact that we can successfully execute the same SDO_RELATE queries in SQL*PLUS rejects this possibility. Perhaps it depends on the amount of data passed to the JDBC driver and the fashion in which it handles it! In our test above we had RELATED 267 geometries. We know that there exist SDO_RELATE queries that run successfully with modelA, but those are queries which ONLY retrieve an EMPTY set of RELATED geometries. In other words we don't get the "TNS end of communication channel" because NO data gets fetched from the server to the client! As soon as we find a SDO_RELATE query which retrieves (RELATES) at least 1 geometry that runs successfully in SQL*PLUS and run it via the Java SDO API - it FAILS! This means that no matter what volume of data is fetched from the server-JDBCThin-SDOAPI-client as long as there is ANY data, the query FAILS in modelA.
Perhaps something internally in the Oracle 9i Server happens that prevent the data being fetch to the JDBCThin for that particular modelA. But what that might be?
Very peculiar problem!

Georgi

Problem with Java Dates and UPDATE for SQL2000

I am having problems with the date formats for Java. I am trying to put the current date time into a SQL table, here it the code I am using:
var Today = new Date()
var conn = Server.CreateObject( "ADODB.Connection" )
conn.Open( "Provider=SQLOLEDB;Server=(local);Database=BillTracking;UID=sa;PWD=;")
var sql = "UPDATE BillAssignments SET DatePosted = " + Today + " WHERE AssignmentID = '" + Request.QueryString("AssignmentID") + "'"
var rs = conn.execute(sql)
I keep getting different errors and I have been unable to find a solution yet. I know that I need to change the date format from the Java standard to the one that SQL likes.
Help....

Please tell us where the Java part of this comes in. I see that you are using JavaScript to load up data via an ADO connection (presumably on an IIS platform) - but I do not see where you are using Java

How can i create messenger with java tv API on STB

deal all.
how can i create messenger with java tv API on STB.
how can Xlets communicate each other?
how?
i am interested in xlet communications with java tv.
is it impossible or not?
help all..

You can create a messenger-style application using JavaTV fairly easily. JavaTV supports standard java.net, and so any IP-based connection is pretty easy to do. The hard part of the application will be text input, but people have been using cellphone keypads to send SMS messages for long enough that they're familiar with doing this. This doesn't work well for long messages, where you really need a decent keyboard, but for short SMS-type messages it's acceptable.
The biggest problem that you need to work around is the return channel. Many receivers only have a dial-up connection, ties up the phone line and potentially costs people money if they don't get free local calls. Always-on return channels (e.g. ADSL or cable modem) are still pretty uncommon, so it's something that you nee to think about. Of course, if you do have an always-on connection then this problem just goes away.
This is really one of those cases that's technically do-able, but the infrastructure may not be there to give users a good experience.

Java Communications API and Java SDK 1.4.2

I just installed the Java Communications API 2.0 on my Windows XP system, with JDK 1.4.2. As per the install instructions, I copied files from the zip into my /lib and /bin directories and set the classpath. However, when I attempt to compile any of the samples, the compiler displays a large number of errors. I know the API documentation only references JDK1.2 -- are there any special tricks to installing on newer JDKs, or will I need to acquire an older JDK to develop?

My path variable is still not being set! Here is the content of my autoexec.bat located on the root directory of C:\
rem - By Groove Setup
PATH=%PATH%;"C:\Program Files\Groove Networks\Groove\Bin"
PATH=%PATH%;C:\PROGRAM FILES\J2SDK1.4.2_07\BIN
/code]
When I type 'path' at the MSDOS C:\ prompt, I receive the following in the get the following:C:\WINDOWS;C:\WINDOWS\COMMAND;\C:\PROGRAM FILES\GROOVE NETWORKS\GROOVE\BIN
As an aside, I noticed that when I perform a search of the my hard drive (c:\), I find two autoexec.bat files. One at the root, and the other in C:\Windows\Command\EBD.
I believe the instructions stated to modify the autoexec.bat at the root directory.
TIA for any assistance. This is really becoming a nusance and taking up quite a bit of my time trying to resolve this problem.
