Encoding in Java XSU internationalisation problem
I have SUN Solaris 2.7, JDK 1.2, Oracle 8.0.5, Oracle XSU 1.2. When I use KOI8-R text encoding and set this in XSU then I see only signs "?????", but if I set ISO-8859-1 then it's Ok. I could work with ISO-8859-1, but in Oracle it stores bad text. Only latinian words was stored successful.
A new user name?
I can think of ways round your problem but can you first provide a reference that indicates that byte 0x80 is the MS936 encoding for the Euro?
P.S. This is a forum and the vast majority of participants, including me, have no direct relationship with Oracle so getting definitive answers from Oracle via this forum is unlikely. If you think you have found a bug in 1.5 and/or 1.6, and I am not convinced you have, you need to report it via the bug database. If it is a bug then the response time for a fix is likely to be months rather than days.
P.P.S No I can't explain why it works in 1.7!

sir i have given lot of effort but i am not able to solve my problem either with notifiers or with occurence fn,probably i do not know how to use these synchronisation tools.

I want to pass along a couple of tips that will get you more and better response on this list.
1) There is an un-written rule that says more "stars" is better than just one star. Giving a one star rating will probably eliminate that responder from individuals that are willing to anser your question.
2) If someone gives you an answer that meets your needs, reply to that answer and say that it worked.
3) If someone suggests that you look at an example, DO IT! LV comes with a wonderful set of examples that demonstate almost all of the core functionality of LV. Familiarity with all of the LV examples will get you through about 80% of the Certified LabVIEW Developer exam.
4) If you have a question first search the examples for something tha
t may help you. If you can not find an example that is exactly what you want, find one that is close and post a question along the lines of "I want to do something similar to example X, how can I modify it to do Y".
5) Some of the greatest LabVIEW minds offer there services and advice for free on this exchange. If you treat them good, they can get you through almost every challenge that can be encountered in LV.
6) If English is not your native language, post your question in the language you favor. There is probably someone around that can help. "We're big, we're bad, we're international!"
Trying to help,
Welcome to the forum!

"How to Resolve ORA-29532 Java 2 Permission Problems in RDBMS 8.1.6 and 8.1.7"
I'm in the process of publishing the following note (134280.1), titled "How to Resolve ORA-29532 Java 2
Permission Problems in RDBMS 8.1.6 and 8.1.7".
It will be accessible from Oracle Support's "Metalink" site.
"How to Resolve ORA-29532 Java 2 Permission Problems in RDBMS 8.1.6 and 8.1.7".
Problem Description
Periodically an application running in the Enterprise Java Engine
(EJE) formerly known as the "Oracle 8i JVM", "the JSERVER component", or
the "Aurora JVM" will fail with a "java 2" permissions error having the
following format :
Note : Message shown below have been reformatted for easier readability.
java.sql.SQLException: ORA-29532: Java call terminated by uncaught Java exception:
usually followed by a detailed error message similar to one of the following
messages :
Example # 1
java.security.AccessControlException: the Permission
(java.net.SocketPermission hostname resolve)
has not been granted by dbms_java.grant_permission to
SchemaProtectionDomain(SCOTT|PolicyTableProxy(SCOTT))
Example # 2
java.security.AccessControlException: the Permission
(java.util.PropertyPermission * read,write)
has not been granted by dbms_java.grant_permission to
SchemaProtectionDomain(SCOTT|PolicyTableProxy(SCOTT))
Example # 3
java.security.AccessControlException: the Permission
(java.io.FilePermission \matt1.gif read)
has not been granted by dbms_java.grant_permission to
SchemaProtectionDomain(SCOTT|PolicyTableProxy(SCOTT))
Explanation
The java 2 permission stated in line # 2 of each of the above "Examples"
has not been granted to the user specified in line 4 of the above "Examples".
Solution Description
The methodology to solve this issue is identical for all java 2 permissions
cases.
1) Format a call "dbms_java.grant_permission" procedure as described below.
2) Logon as SYS or SYSTEM
3) Issue the TWO commands shown below
4) Logoff as SYS or SYSTEM
5) Retry your application
For Example # 1
1) Logon as SYS or SYSTEM
2) Issue the following commands :
a) call dbms_java.grant_permission('SCOTT',
'java.net.SocketPermission',
'hostname',
'resolve');
b) commit;
Note: Commit is mandatory !!
3) Logoff as SYS or SYSTEM
4) Retry your application
For Example # 2
1) Logon as SYS or SYSTEM
2) Issue the following commands :
a) call dbms_java.grant_permission('SCOTT',
'java.util.PropertyPermission',
'read,write');
b) commit;
Note: Commit is mandatory !!
3) Logoff as SYS or SYSTEM
4) Retry your application
For Example # 3
1) Logon as SYS or SYSTEM
2) Issue the following commands :
a) call dbms_java.grant_permission('SCOTT',
'java.io.FilePermission',
'\matt1.gif',
'read');
b) commit;
Note: Commit is mandatory !!
3) Logoff as SYS or SYSTEM
4) Retry your application

"Security For Oracle8i Java Applications"
The RDBMS 8.1.7 version can be found at :
http://otn.oracle.com/docs/products/oracle8i/doc_library/817_doc/java.817/index.htmHi, Don,
I solved the problem of security exception I mentioned at java procedure topic as following:
ORA-29532: Java call terminated by uncaught Java exception: java.lang.SecurityException
I tried to use your solution as following:
call dbms_java.grant_permission('SDE', 'java.net.SocketPermission', 'ORCL.COHPA.UCF.EDU','resolve');
but SQL*plus gave me a error message:
invalid collumn.
What's the problem?
However, I call a grant command as following:
SQL> grant JAVASYSPRIV to sde;
and then that exception is gone. What's the difference between dbms_java.grant_permission and grant command?
Thanks
Bing

Finding a Gif Encoder for Java Advanced Imaging (JAI)
I'm trying to find the GIF encoder for Java Advanced Imaging. I keep reading all over the place that there is one, but for the life of me I can't figure out where it is supposed to be. Could anyone please enlighten me?
ThanksAfter I installed this, it still doesn't report gif as a possible encoding type:
String[] codecs = ImageCodec.getEncoderNames(img, null);
for (int j = 0; j < codecs.length; j++) {
String codec = codecs[j];
System.out.println (codec);
}only reports the following types available:
pnm
jpeg
tiff

Output encoding in Java mapping ?
Hello,
I have written a Java mapping which reads an input document and creates an output document. My problem is, the German special characters are lost in the output document (wrong characters). This is strange, because I am only using regular DOM methods for adding the output nodes and values. Anybody has an idea where I have to explicitly define the output encoding ? XI automatically uses UTF-8, I am using the StandardDOMWriter class of the com.inqmy.lib.xml package from XI, and DocumentBuilder from javax.xml.parsers.
But the output is wrong nevertheless. I think the encoding is already set in the OutputStream input variable of the execute methods. So no need to be changed (?)
Code sample below:
public void execute(InputStream in, OutputStream out) throws StreamTransformationException {
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document idoc = documentBuilder.parse(in); // input document
Document odoc = documentBuilder.newDocument(); // output document
// create some elements and values with helper method below
// write output document to stream
odoc.appendChild(oRoot);
StandardDOMWriter sdw = new StandardDOMWriter();
sdw.write(odoc, out, null);
private Element createElement(String elementName, String value, Element parent, Document doc) {
Element element = createElement(elementName, parent, doc);
// here we put the input content to output value
element.appendChild(doc.createTextNode(value));
// ok, special character still there:
trace.addInfo("Read back: " + getNodeValue(element));
return element;
CSYI solved the problem. For some reason, the inqmy parser does not work correctly. If I remember correctly, the SapXMLToolkit (from where it comes), is deprecated anyway.
Instead I use now standard JAXP transform streaming, and that works fine:
// commented code does not convert german special characters correctly:
//StandardDOMWriter sdw = new StandardDOMWriter();
//sdw.write(odoc, out, null);
// Serialisation through Transform.
DOMSource domSource = new DOMSource(odoc);
StreamResult streamResult = new StreamResult(out);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING,"UTF-8");
serializer.setOutputProperty(OutputKeys.INDENT,"yes");
serializer.transform(domSource, streamResult);

Get canvas.toDataURL('image/jpeg') and convert base64 encoding to java.sql.Blob
Convert canvas.toDataURL('image/jpeg') to java.sql.Blob.
I am using oracle adf so I am able to action a backing bean from javascript and pass in parameters as a map. I pass in the canvas.toDataURL('image/jpeg') which I then try to decode in my bean. Using BASE64Decoder and the converting the bytearray to a file I can see the image is corrupted as I can't open the file thus converting the bytearray to blob is also a waste.
Has anyone any ideas on base64 encoding from canvas.toDataURL to file or Blob?Use Case:
A jsf page that enables a user to take photos using the HTML5 canvas feature - interact with webcam -, take photos and upload to profile
1. I have created the jsf page with the javascript below; this pops up as a dialog and works okay and onclick an upload image, triggers the snapImage javascript function below and sends the imgURL parameter to the serverside managedbean
<!-- java script-->
function snapImage(event){
var canvas = AdfPage.PAGE.findComponent('canvas');
AdfCustomEvent.queue(event.getSource(),"getCamImage",{imgURL:canvas.toDataURL('image/jpeg'),true);
event.cancel();
<!-- bean -->
public void getCamImage(ClientEvent ce){
String url=(String)ce.getAttributes().get("imgURL");
decodeBase64URLToBlob(url);
private BlobDomain decodeBaseB4URLToBlob(String url64){
BASE64Decoder de=new BASE64Decoder();
byte[] bytes=de.decode(url64);
File file=new File("abc.jpg");
InputStream in = new ByteArrayInputStream(bytes);
BufferedImage bImageFromConvert = ImageIO.read(in);
in.close();
ImageIO.write(bImageFromConvert, "jpg", file);
return createBlobDomainFromFile(file);
----problem---
Accessing the generated jpeg file shows the image is corrupted, probably missing bytes or encode/decoder issues.and the blob image after uploading to database is saved as a binary stream which ondownload doesnt render as an image or anything i know of.
Is there anyways of achieving the conversion without errors? -

Not exactly a Java.Sound.* problem...
Hello folks! I am writing a piece of code that takes a .wav file, encoded with 16 bits/sample, and has to perform a "thersholding" operation in these samples. That is, that groups of samples that don't have enough mean energy, shall not be included in the new .wav file that will contain the thresholded sample (the whole process is a short of compression).
The problem is, that for some reason I haven't discovered yet, only half of the bytes of the original file are found in the final file! (But, the thresholding mechanism works well in these half samples :P)

Something like <XSL:Import> or <XSL:Include>
You can import other stylesheets and use the templates they contain. You can also import one or more stylesheets and then optionally redefine any templates that they define.
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:java="http://xml.apache.org/xslt/java" exclude-result-prefixes="java">
<!-- import the core functionality -->
<xsl:import href="../common/generic_csv.xslt"/>
Some other templating code...
</xsl:stylesheet>Is this what you are after? -
XSU Insert Problem with ORA-00001
Hi,
I am writing an application which will extract a series of tables from a source database and then populate a target database.
I am using the XSU utility to extract each table individually into its own physical XML file.
The extraction goes well, but on some tables the population has a problem.
During the population process, the OracleXMLSave utility throws an exception:
Error in loadFile oracle.xml.sql.OracleXMLSQLException: Exception 'java.sql.SQLException:ORA-00001: unique constraint (MYDB.SYS_C001346) violated encountered during processing ROW element 97All prior XML row changes were rolled back. in the XML document.
I know for a fact that there is no duplicate primary key entries in the physical xml file.
I am using the XSU - XSU12_ver2_1_0_beta with JDBC2.0 (JDK1.3 and loadable into Oracle8.1.7
Has anyone seen this?
I am at a critical point in the project. Any help appreciated.

How can I in the java class DYNAMICALLY set up the encoding so that the sysytem at the runtime will acccept the Cyrillic characters. Nonsensical. Java strings are unicode. Always. If you have a java string and you pass it to a java method it remains a java string.
And the Cyrillic characters are mapped into unicode. So a java string can certainly contain them.
Your problem probably lies either in getting Cyrillic into the string or setting up the "display" so it get displayed.
You first step should be in understanding that there is a difference between data (such as what is in a string) and display (what you see on a screen.) Data is always mapped when displayed. Understanding how that mapping occurs is important. -
I have downloaded the code related to Byte Pair encoding. It is
specific to C and C++ languages. I tried porting the code from c to Java, but i have faced problem with the length available in C & java for character. In java it takes 2 bytes but in C it is one. I have
been trying to get the working code for Java. But till now i didn't get the proper one. Please help me. link has given below.

http://www.csse.monash.edu.au/cluster/RJK/Compress/bpe.c (for

if any body have a example code for Byte Pair Encoding,pls give the link
Thanks and Regards,
B.Rajesh1. The Java type byte is probably what you want to use for the C type char.
2. I think the following paragraph is incorrect:
LZW compression adapts linearly to frequently occurring patterns, building up strings one character at a time. The BPE algorithm adapts exponentially to patterns, since both bytes in a pair can represent previously defined pair codes. The previously defined pair codes can themselves contain nested codes and can expand into long strings.
I don't know the details of LZW, but my understanding of the LZ family is that they also have exponential adaption for the same reason as BPE. The primary difference, ISTM, is that LZ increases the size of the tokens beyond a byte. -
Jpeg encoding with imageio - pink distortion problem

In my program, I can only play .au files in Java.. I have a few .wavs that I would like to incorporate into my program, but I need to change them into .au . Ive tried using COOL EDIT PRO 2 and SOUND FORGE 6.0 to open up the .wavs, then save them as .au .. I run my Java program, but an error comes up saying INVALID ENCODING and INVALID FILE TYPE.. Does anyone have a solution for this frustrating problem I have? It's very urgent and I need your help, thanks...
It took me 4 clicks and 12 keystrokes to find this.

I typed sound files <enter>
The first one looked good to me, click!

SSO java sample application problem
Hi all,
I am trying to run the SSO java sample application, but am experiencing a problem:
When I request the papp.jsp page I end up in an infinte loop, caught between papp.jsp and ssosignon.jsp.
An earlier thread in this forum discussed the same problem, guessing that the cookie handling was the problem. This thread recommended a particlar servlet , ShowCookie, for inspecting the cookies for the current session.
I have installed this cookie on the server, but don't see anything but one cookie, JSESSIONID.
At present I am running the jsp sample app on a Tomcat server, while Oracle 9iAS with sso and portal is running on another machine on the LAN.
The configuration of the SSO sample application is as follows:
Cut from SSOEnablerJspBean.java:
// Listener token for this partner application name
private static String m_listenerToken = "wmli007251:8080";
// Partner application session cookie name
private static String m_cookieName = "SSO_PAPP_JSP_ID";
// Partner application session domain
private static String m_cookieDomain = "wmli007251:8080/";
// Partner application session path scope
private static String m_cookiePath = "/";
// Host name of the database
private static String m_dbHostName = "wmsi001370";
// Port for database
private static String m_dbPort = "1521";
// Sehema name
private static String m_dbSchemaName = "testpartnerapp";
// Schema password
private static String m_dbSchemaPasswd = "testpartnerapp";
// Database SID name
private static String m_dbSID = "IASDB.WMDATA.DK";
// Requested URL (User requested page)
private static String m_requestUrl = "http://wmli007251:8080/testsso/papp.jsp";
// Cancel URL(Home page for this application which don't require authentication)
private static String m_cancelUrl = "http://wmli007251:8080/testsso/fejl.html";
Values specified in the Oracle Portal partner app administration page:
ID: 1326
Token: O87JOE971326
Encryption key: 67854625C8B9BE96
Logon-URL: http://wmsi001370:7777/pls/orasso/orasso.wwsso_app_admin.ls_login
single signoff-URL: http://wmsi001370:7777/pls/orasso/orasso.wwsso_app_admin.ls_logout
Name: testsso
Start-URL: http://wmli007251:8080/testsso/
Succes-URL: http://wmli007251:8080/testsso/ssosignon.jsp
Log off-URL: http://wmli007251:8080/testsso/papplogoff.jsp
Finally I have specified the cookie version to be v1.0 when running the regapp.sql script. Other parameters for this script are copied from the values specified above.
Unfortunately the discussion in the earlier thread did not go any further but to recognize the cookieproblem, so I am now looking for help to move further on from here.
Any ideas will be greatly appreciated!
/MadsPierre - When you work on the sample application, you should test the pages in a separate browser instance. Don't use the Run Page links from the Builder. The sample app has a different authentication scheme from that used in the development environment so it'll work better for you to use a separate development browser from the application testing browser. In the testing browser, to request the page you just modified, login to the application, then change the page ID in the URL. Then put some navigation controls into the application so you can run your page more easily by clicking links from other pages.
