Troubles with Java Comm API

I am trying to use the Java Comm API with Windows 2000 and I can enumerate the ports (I am almost sure that the problem is the dll). Do anybody knows a solution?

Where is the problem?

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.

Deploying Java Comm API

Hi,
I am developing an applet which uses Java Comm API. I'm running into some deployment issue. My understanding is that Java Comm API needs to have win32com.dll and javax.comm.properties files installed on the client machine for my applet to use Comm API. Is there a way around this? The ideal way will be to have everything (win32com.dll and javax.comm.properties) in a jar file so that it doesn't need to install any file on the client machine. However looking at previous posts, I don't think that's possible with Java Plug-in. Will I be able to utilize Java WebStart to accomplish this? I'll be interested to find how other people deploy Java Comm API. Thanks in advance.
Regards,
Joy

I�ve developed a solution to this problem. I created a class that creates the javax.comm.properties file where the comm.jar lib looks for it. The trick is to run the method that creates the file before the lib looks for it.
I show you the example of my code:
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
public final class PrinterInit {
    public static void printerInit(){
        String archivoConf =
            System.getProperty("java.home") + File.separator + "lib" +
            File.separator + "javax.comm.properties";
        try {
            BufferedWriter out = new BufferedWriter(new FileWriter(archivoConf));
            out.write(
                "#"+ "\n" +
                "# Drivers loaded by the Java Communications API standard extension"+ "\n" +
                "# at initialization time "+ "\n" +
                "# "+ "\n" +
                "# Format: "+ "\n" +
                "#   Each line must contain ONE driver definition only "+ "\n" +
                "#   Each line must be of the form: "+ "\n" +
                "#           driver=<ClassName> "+ "\n" +
                "#       No spaces or tabs in the line. "+ "\n" +
                "#       ClassName must implement the interface javax.comm.CommDriver "+ "\n" +
                "#           example: driver=Win32Serial"+ "\n" +
                "#   "+ "\n" +
                "#"+ "\n" +
                "# The hash(#) character indicates comment till end of line."+ "\n" +
                "#"+ "\n" +
                "# Windows Serial Driver"+ "\n" +
                "Driver=com.sun.comm.Win32Driver" + "\n");
            out.close();
        } catch (IOException e) {
            System.err.println("No se pudo crear el archivo:" + "javax.comm.properties");
            System.err.println("Ruta completa:" + archivoConf);
}Before opening the port I call
PrinterInit.printerInit();This example writes de javax.comm.properties file needed for a windows implementation. You can change the value of the Driver property for the system you are using.
Good Luck!

Doubt handling Clob columns with Java JDBC api

Hi,
we have a doubt handling Clob columns with Java JDBC api.
Reading Oracle 10g official documentation (document b10979.pdf, page 236), we found this note:
============================================
To write LOB data, the application must acquire a write lock on the LOB object. One way to accomplish this is through a SELECT FOR UPDATE. Also, disable auto-commit mode.
============================================
We also found a java sample code about how to handle Lob objects at this URL:
http://www.oracle.com/technology/sample_code/tech/java/sqlj_jdbc/files/advanced/LOBSample/LOBSample.java.html
In our java2 application, we access Clob objects in a quite different
manner: we use normal setString() and getString() methods, as described into paragraph "Shortcuts For Inserting and Retrieving CLOB Data"
(document b10979.pdf, page 244).
Using those methods, we never lock the table row by a SELECT FOR UPDATE statement (as described into the note above). We use simply SELECT, UPDATE and INSERT prepared statement.
In this way we can insert both clob objects and normal timestamp, number and other types with a single insert statement. Idem for update.
To recap, our question is:
Is it mandatory to create a SELECT FOR UPDATE statement when updating clob data? What may be the consequences if we don't use it? It is also correct to insert with a single sql statement both clob and not clob data using the setString() method for the clob types? And more than one lob column in the same record?
bye,
luca acri.

And columns of type FLOAT. These also have, for some unknown reason a metadata type of OTHER, and a type string of 'FLOAT'. Yet PreparedStatement.setNull(x, Types.OTHER) doesn't work and setNull(x, Types.DECIMAL) does.

What deis this message mean? How to make you serial port support work?

and what does this error message mean??
The package was installed accordingly to "Java(tm) Communications API Linux Installation Instructions":

Problem in Accessing serial port using java comm Api

I have installed java comm Api in my pc.
i have gone through the instalation instruction which comes on this package.
I have done the instalation like this
Copy win32com.dll to my <JDK>\bin directory.
Copy comm.jar to my <JDK>\lib directory.
Copy javax.comm.properties to my <JDK>\lib directory.
and restart the system.
But when i run the BlackBox , it is giving me message
"serial port not found".
Can any one tell me , what is the exact problem ?

I'm not sure what you mean by BlackBox, but I have used the COMM api extensively.
The majority of problems is that the api cannot see the serial port (which is what you are describing) and this is caused by incorrect placing of the javax.comm.properties file.
As well as <JDK>\lib, try putting it into <JRE>\lib as well. That has often solved problems on my setup.

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?

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 comm api in 64-bit Linux

I apologise if this is off-topic. I can't find a suitable forum, I tried posting in the Java plugin forum, but no luck there. I would appreciate any ideas to find a solution.
I am trying to use the java comm api to read and write to the serial port but I am getting the following error:
Error loading LinuxSerialParallel: java.lang.UnsatisfiedLinkError: /usr/lib64/libLinuxSerialParallel.so: Can't load IA 32-bit .so on a AMD 64-bit platform
I am using openSUSE 10.2 (X86-64) which uses Linux 2.6.18.2-34-default x86_64.
I tried Switching to a 32-bit version of java (1.4.2) from within Eclipse and I always run Eclipse in 32-bit java (/usr/share/eclipse/eclipse -vm /usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre/bin/java) but I still get this error.
Is there anything I can do to get the java comm api working on a 64-bit system?
Is the java comm api still being developed and maintained? It does not look like it is?
I've done some searching on the web and I find there is an open source version of the java comm api called RXTX but the website at http://www.rxtx.org/ is not very readable. I don't think I know enough to install this on my system.
I would appreciate any ideas to get this working.
Thanks,
Martin

I'm stuck again so I would appreciate some more help.
I've managed to install the Sun 1.6 JDK and configure
and make rxtx.Any small amount of progress is still progress. :)
>
But it still does not work, I get the following error
when I run the SerialDemo:<snip>
>
It seems to be com.sun.comm which is not finding its
native binary not rxtx! No, it's finding the shared library, unless there are a few more lines at the start of your error message that look like this:
Error loading LinuxSerialParallel: java.lang.UnsatisfiedLinkError:
no LinuxSerialParallel in java.library.pathIt's not finding the function it is looking for in that library.
This is what confuses me, the
instructions say install the Solaris version of comm
api (http://www.rxtx.org/ how-to said Solaris Sparc
and the rxtx INSTALL file said Solaris x86 so I tried
both in turn and neither worked) Same here after downloading the latest stuff to my x86 Linux box. I received a similar UnsatisfiedLinkError. I checked the shared libraries and the functions were not in it.
normally these would
call the Solaris binary drivers but I assume this has
to be redirected to rxtx which calls its own
binaries?Yes. There is a part of RXTX called JCL (Java Comm for Linux) that handles that.
http://www.geeksville.com/~kevinh/linuxcomm.html
However, I think the problem is that Sun's API has changed since the RXTX How-To was written. Try downloading the 'comm.jar' at the bottom of the page. It says:
comm.jar, 2.0.3, generic, English (3rd party backward compatibility, only), EnglishUnzip it and copy the comm.jar file to the 'jre/lib/ext' folder of the JDK/JVM where everything else RXTX created was placed.
After doing this the SerialDemo app started for me without errors.

[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,

-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

Trouble with java security manager

I have set up a security manager for my webapp running on Tomcat. The application enables the user to write his own scripts using Javascript, that's why I need to set up a security manager.
Using Rhino as script interpreter, it is possible to use the standard java security mechanisms, e.g. using the security manager to handle the scripts' rights.
I've added the following lines to my policy file:
// give server all rights
grant codeBase "file:webapp/WEB-INF/-" {
     permission java.security.AllPermission;
//rights granted to scripts
grant codeBase "file:restrictedClient" {
     permission java.io.FilePermission "webapp/WEB-INF/lib/js.jar", "read";
I've assigned the scripts to the "restrictedClient" code base. However, the script execution fails as the script does not have the permission to access or define classes of any package (even standard java packages like java.lang or java.math).
In java.security, I have found the following comment:
# List of comma-separated packages that start with or equal this string
# will cause a security exception to be thrown when
# passed to checkPackageDefinition unless the
# corresponding RuntimePermission ("defineClassInPackage."+package) has
# been granted.
# by default, no packages are restricted for definition, and none of
# the class loaders supplied with the JDK call checkPackageDefinition.
#package.definition=
I now wonder, why the checkPackageDefinition is checked though there's no entry for any package to be checked.
Extending the policy file like
grant codeBase "file:restrictedClient" {
     permission java.lang.RuntimePermission "accessClassInPackage.webapp/WEB-INF/classes/org/mozilla/javascript";
     permission java.io.FilePermission "webapp/WEB-INF/lib/js.jar", "read";
     permission java.lang.RuntimePermission "defineClassInPackage.java.io";
     permission java.lang.RuntimePermission "defineClassInPackage.java.util";
     permission java.lang.RuntimePermission "defineClassInPackage.java.net";
     permission java.lang.RuntimePermission "defineClassInPackage.java.sql";
     permission java.lang.RuntimePermission "defineClassInPackage.java.lang";
     permission java.lang.RuntimePermission "defineClassInPackage.java.math";
     permission java.lang.RuntimePermission "de.methodpark.pkit.facade.impl";
works, but an unpleasant feeling remains :-).
Rhino creates an own classloader for script execution. Could that be the source of the strange behaviour?
Any help would be appreciated!

David,
I was glad to see your post regarding WLS 9.2 and the troubles with enabling Java Security Manager.
Were you able to learn any more on things like - why doesn't the admin console work when the security manager is enabled with the default policy file. Also, why is it so difficult to add permissions for your own applications and get them to actually work.
I'd be curious to see if you were able to get it to work or if you have any insights or resources that can help with this as we are really struggling to get a restrictive policy file that works.
Thanks,
D

Issue with JAVA Mail API

Hi
We have a requirement to create a custom e mail. For the same I am trying to use Java Mail API.I am facing an issue with the following code:
session session1 = session.getInstance(properties, null);
System gives an error Sourced file: inline evaluation of: ``Properties props = new Properties(); session session1 = session.getInstance(prop . . . '' : Typed variable declaration : Class: session not found in namespace
Is there some specific API i need to import for session class. Kindly suggest.

import java.io.File;
import java.net.*;
// SUBSTITUTE YOUR EMAIL ADDRESSES HERE!!!
String to =<email address>;
String from =<email address>;
// SUBSTITUTE YOUR ISP'S MAIL SERVER HERE!!!
String host = <smtp host name>;
String user = <smtp user name>;
// Create properties, get Session
// Properties props = new Properties();
Properties props = System.getProperties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", host);
props.put("mail.debug", "false");
props.put("mail.smtp.auth", "false");
props.put("mail.user",user);
props.put("mail.from",from);
Session d_session = Session.getInstance(props,null);//Authenticator object need to be set
Message msg = new MimeMessage(d_session);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject("Test E-Mail through Java");
msg.setSentDate(new Date());
msg.setText("This is a test of sending a " +
"plain text e-mail through Java.\n" +
"Here is line 2.");
Transport.send(msg);
