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.

Problems with java logging utility

Hi,
I am having a few problems with java's logging framework.
When I create a logger using
Logger log = Logger.getLogger("my.com");
and log my messages using this "log" object, the messages are logged to System.err which is my console. But when I add a Filehandler to this Logger object, I get log messages both in the file and the standard error.
The problem is that I want to supress logging to the standard error but do not know how to do this. I tried a few things:
1) If I close the standard error (System.err.close() ), things work fine but I can't afford doing this since other parts of my application might use System.err for some purpose.
2) I thought that , by default, a ConsoleHandler object is added to the Logger object. So I thought I might get around the problem if I close() this ConsoleHandler object. But, to my surprise, log.getHandlers() returns an empty array by default. So there is no ConsoleHandler attached to it.
Any info. regarding it will be very much appreciated.
Thanks,
Arch.

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?

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.

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,

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.

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

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,

-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

You probably made the same mistake as I did and added the tables manually to the "sample" database instead of the "sun-appserv-samples" database.

Practical use of Java Logging API

There was a recent technical tip about the Java Logging API, but after reading it I still don't understand how to use it in a real situation.
Can anyone help me with this with a practical example?
At the moment I have try-catch clauses that catch exceptions and print a message in a System.err log that I can consult if there's a specific problem.
How should I be using the Logging API? I feel sure that it can help me, but can't see how.
Thanks for any practical information.

What if you don't want to write to system.err anymore? What if you need to write something to the windows event log? What if system.err is irrelevant (nt service), ...
Btw, lots of examples on the JDK1.4 logging api:

Problems with java j2re using mozilla

Hi,
i'm using j2re1.4.2_05 plugin for mozilla in linux (Fedora Core 2). My internet access goes throught a router (SMC Networks ISDN Barricade SMC7301TA). It's settings can be edited throught a web browser LAN connection. And here the problems begin. On routers settings page a java output console (for error and other messages) is running, which doesn't work, despite java applications on other web pages work well (I tested it on sun's java test page and it's working properly). Java console exits the following errorr message:
>
load: class DynamicTable.class not found.
java.lang.ClassNotFoundException: DynamicTable.class

     ... 10 more
Is there a way to fix this problem? Cause without the command output it's mearly unpossible to configure the router.

Yes i can make changes. Not everything is realised with java, just the output console, which reports if the changes i made succeded, prints out logs, gives additional info about some settings etc. So, i can make changes, but i have no response, for example: everytime i save something i don't know if the save was succesful. I can't take a look at IP routing table and DHCP configuration...
On windows xp, using internet explorer (the default version for xp) everything works perfect. But mozilla for windows has also problems with java. I know i can still change settings on wins, but right now i'm having some problems with networking on linux and i have to set things up in it (besides i use wins only because of school purposes).

Problems with Java DOM Mapping

Hi Experts,
as part of my diploma-thesis I have to write a java DOM-Mapping, which mapps the following incoming message:
<mt_MappingOUT>
<set>
<set_Element_01>...</set_Element_01>
<set_Element_02>... </set_Element_02>
<set_Element_03>... </set_Element_02>
<set_Element_10> </set_Element_10>
</set>
</mt_MappingOUT>
to the following outgoinig message:
<mt_MappingIN>
<TABLE>
<item>
<item_FIELD_01> </item_FIELD_01>
<item_FIELD_10> <item_FIELD_10>
<i/tem>
</TABLE>
</mt_MappingIN>
I am not a very experienced Java-Developer. You can see my code down there, which I tried to implement according to some bloggs; unfortunately the result is not what I want to have

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.
Steve.
