Sending udp packets using java and receiving it using c
hi,
Is it possible to send udp packets using java and receive the same using c??????? if yes.... plz help immediately.The biggest issue is data format. The JVM is big endian, with 16-bit characters. The machine running 'C' could be almost anything. A (signed!) byte array is probably the easiest unit of exchange.
The Java program has its own techniques for storing/retrieving data to/from the byte array - and the C program has its own techniques. ASCII Strings are often the easiest to exchange - just convert the java String objects to byte array and send them.
apaliwal1 has already given the UDP calls to send/receive the data. -
PMML Export using Java and ODM 10.2
I'm attempting to export a model I've built in ODM using Java and the example code in dmexpimpdemo.java. I'm getting an error when trying to set an additional attribute to export the data as PMML.
exportTask.setFormat(ImportExportFormat.PMML2_1);
If I call this method (with any ImportExportFormat) I get the exception:
javax.datamining.JDMUnsupportedFeatureException: Unsupported ExportTask for PMML2_1
What is the proper way to export a model as PMML using the JAVA APIs?PMML Export is not supported by the ODM 10.2. Hence you see unsupported exception.
ODM 10.2 supports only Oracle native format support for the mining model export and import. For more details about the usage refer to the demo program dmexpimpdemo.java.
To download sample programs from OTN http://www.oracle.com/technology/products/bi/odm/samples/odm_sample_code_0805.zip
For decision tree model you can export the model details in PMML format using the DBMS_DATA_MINING.get_model_details_xml. For example, the following query returns the PMML format decision tree model as an Oracle Database XMLType
select dbms_data_mining.get_model_details_xml('TREE_MODEL').extract('/') AS DT_DETAILS FROM dual

Error using java and javascript
I have a jsp page that links to a bean and is working fine (getting data from the database).
On a html form I have a button with a picture that fires off javascript when clicked:
<BUTTON TYPE=reset onclick=showinfo('<%=index%>')>
<IMG SRC="http://localhost:8080/Portal/Images/q2.bmp" ALT="Info">
</BUTTON>
The javascript function just opens a new window and displays the text sent in:
<Script Language=JavaScript>
function showinfo(arrayindex)
InfoWin=window.open("","InfoWin","width=345,height=220");
InfoWin.document.write(arrayindex);
return false;
</Script>
Well in the above example index is a number (pulled from the database using a java bean and javascript converts it into a string then the function displays it correctly. If I replace <%=index%> with regular text it works fine as well(because java isn't used to pull data)! The problem occurs when I retrieve text data from the database and send it to the function. The web page gives errors about a nonterminating string. But I can move the code to somewhere else on the form(as long as I don't send it to java script) and it will print the text to the screen. I can also view the source of the web page and the html shows the text from the data base as if I hard coded the text into the javascript!!!!!!!!!!!!!!!!!
This must be a bug between java and javascript!
-can pass numbers(from a database) between the two
-can't pass text (from a database)between the two
Any info would help!Found the problem myself!
I am using an odbc connection to msaccess and the spaces in the text was messing things up!
After taking out the spaces it worked again. -
Query resultset to xml using java and XML schema
Hi,
I query data using JDBC and I want to store it to an XML file which has a well defined XML schema. I searched a lot in the forum but did not find an answer. Please guide me to create this program.
I have managed to use JDBC to get result set but I do not know how to export is to XML using XSD and Java.
Please help.
Regards,
RaviI have managed to use JDBC to get result set but I do
not know how to export is to XML using XSD and Java.Export using XSD? Schemas are for validation.
Iterate through the result set, and build up the XML stream by creating an entry for each row.
Another way to do it is to load the ResultSet into a Java object and serialize that to XML using something like XStream.

How can I open a program using Java and then perform certain tasks with it?
For example, and this is just an example, I want to write a Java program that opens MS Paint and then manipulates that program. This can be useful to automate certain tasks.
My question is whether this can be done writing Java code and if so how? If not possible, would I need to use a scripting language instead?write a Java program that opens MS Paint and then
manipulates that program. This can be useful to
automate certain tasks."manipulates" is a too wide term. Let me narrow down:
1. If you want to open (run) the program and then shut (kill) it down it is possible and fairly trivial to do in java. Look up Runtime and Process classes in java.lang package
2. If you want to open the program and edit some image/document in the opened program. It is very difficult in java. May be possible... using some Java/COM bridge, assuming your native program is COM/Active-x compliant. Note: these things go beyond the boundary of JVM and needs to interact with host OS and involves shared memory, ipc and all "low level" stuffs.
If you want to be able to play around with these COM/Activex apps- choose .NET instead :-)
3) You can open the program from java and pass it some command line arg as in (1) above and then the program will load that document/image at startup automatically. You may then edit the doc/image thru that program itself. However, Java is not doing anything for you here, other than just starting off your native mspaint.exe ot notepad.exe.

Hi....
I am strugling for a code to write from database to xml output instead of what i have written in flat file....could anyone please help me out...to do this and again read the same back to the database using java...Hi,
In java world, there is a tutorial on what you are looking for :
http://www.javaworld.com/javaworld/jw-01-2000/jw-01-dbxml_p.html
It uses SAX/DOM parsers to translate XML data into the appropriate fields of the database and visa-versa.
Hope it helps. -

Could anybody please advise me this is not supported or if i am missing something.
Thanks in advanceThis is expected behavior; the formats that do not work for you are unavailable in Crystal Reports for Eclipse. To get access to those formats you will need to use the managed version of the Report Application Server API; this is available in Crystal Reports Server, Business Objects Edge and Business Objects Enterprise.

Store XML data as relational data into Oracle tables using Java and XMLType
I want to store xml data into an Oracle 11g table as relational storage, not as CLOB or Binary storage. Then I should also be able to query and fetch this data from table into an XML file.
Any hint on how to write java code using XMLType to achieve this?
Any help would be appreciated.Thanks for the explanation. I still have few confusions. I will try to elaborate my requirement with a simple example...
I have the following xsd and xml files. "note" would be the table in database and "to", "from", "heading" and "body" would be the columns of note table. "Tove", "Jan", "Reminder" and "Don't forget me this weekend!" would go as data in one row of note table.
How do I create note table with the xml schema (xsd file)?
Should the note table be of XMLType or the columns?
How do I load the XML data into the columns of note table?
How do I retrieve the row of note table as XML file?
XML Schema:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.xxxxx.com"
xmlns="http://www.xxxxx.com"
elementFormDefault="qualified">
<xs:element name="note">
<xs:complexType>
<xs:sequence>
<xs:element name="to" type="xs:string"/>
<xs:element name="from" type="xs:string"/>
<xs:element name="heading" type="xs:string"/>
<xs:element name="body" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
XML Data:
<?xml version="1.0"?>
<note>
<to>Tove</to>
<from>Jan</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>

Using Java and EditRocket with iMac?
I am trying to compile a program on my iMac using EditRocket. I have to write programs in Java. I am having no luck on my own and AppleCare couldn't help me either. I cannot locate the Java in my computer and in order to use Editrocket I have to link the compiler to the Javac which I have not been able to figure out how to do. I am having dificulty locating the JDK on my computer and I am having difficulty downloading JDK from java.sun.com as well.
Am I going about this totally wrong? Can someone help direct me to stpe by step instructions so I can get up and running for my class? No one at the college seems to be able to help because everything they use is PC based, however my professor told me that I could use a MAC to do this work because the information is out there.
Is there another program I should be using or something?its not only possible but easy

Firefox fails to load the GoToMeeting application and says that I should enable Java. The Java plug-in is already enabled. I don't know what to do to get this working again.
I read somwhere that firefox disables certain versions of java because it might give control of your computer to other malicious websites
I think you have to go to the java website and down load the version you need and enable it in firefox's prefrences
Sorry I may be a veteran in using firefox, but I know very little since I hardly had problems with mozilla untill just very recently hope this helps -
The Oracle Database Programming using Java and Web services book is out
This book http://www.amazon.com/gp/product/1555583296 shows how to build pragmatic applications using the combination of PL/SQL, Java in the database, JDBC, SQLJ, JPublisher, and Web services. It is intented for database developers, DBA, data architects, Java developers and Web services assemblers.
My blog http://db360.blogspot.com/ and the free/sample chapter http://www.oracle.com/technology/books/pdfs/mensah_ch1.pdf will give you a feel of the content.
Enjoy, KuassiHi Kuassi,
Thanks for letting us know that your book is available. I have been following one of your articles about "Virtualize Your Oracle Database with Web Services". More specifically "The Database as Web Services Consumer". I think that this is an area that has in the past been under estimated as to the potential benefits.
I am currently trying to develop a solution that consumes several interfaces with a couple of them being published web services, so an ideal solution. I have then spent the last three weeks having to read up about the architecture of Java in the database, Jpublisher and make sense of how it all works together.
I have got very close to getting one of the web services to work but failed due to using 10gR2 where all the java & libraries has moved to version 1.5. The solution is to load the jdk1.4.2 and configure jpublisher to use this. So far so good except this is not available on some platforms, Windows - 64 bit (not itanium).
The configuration is proving very challenging but will hopefully reap rewards.
(Thought I would give you some background to my experience).
Anyway my question to you is having looked at Jdeveloper it appears to do almost anything except consume services into the database, also with Java now being at version 1.5 outside the database for 10gR2 and supporting 1.4 inside, do you see some alignment of these in future database releases?
Finally off to buy your book now as no doubt there is a huge amount more to learn.
Kind Regards

Read mail using java, and set the mail
How can I read mail and set message "SEEN" with java? (javax.mail)
IMAP supports flags; so there are no problems, just using
msg.setFlag(Flags.Flag.SEEN, true);
but,
POP3 does not support flags; how can I solve this in POP3? I have searched for this problem, found that I can just check for the header "Status", but this header does not exsist. Then I tried to add this header, but again, then I got IllegalWriteException cause pop3-msg is writeprotected (yes: I opened the folder READ_WRITE); so; does anyone know how I can solve this problem?Hi !
Could u plz send me the code u r having for reading mails using IMAP...actually v r trying to read mails from outlook but due to some security reasons our team has decided not to use pop3 ...
