How to use DOMParser from an Applet / Or, how to parse XML from an Applet?

Hey,
As stating in the subject line, I wonder how to do it without getting an �Access Denied� error.
I would like to parse a XML file that has external DTD pointing to a SYSTEM location. Yes, I can change it to a public location. However, in either way, I have problems to use DOMBuilder to parse the xml file. The application always throws the security exception.
I tried to use the DOMParser from org.apache.xerces.parsers to parse the xml file. I set the DOMParser to ignore parsing the external DTD, and use the DOMParser.parse(InputSource) to parse the xml file from a giving URL. However, I get null of the result document.
Does anyone know how to parse the XML from an Applet? Or, does anyone know how to use the DOMParser from an Applet?
Thank you very much,

If the document resides on the local filesystem, you will need to sign a CAB or JAR for the applet to circumvent the sandbox's security restrictions. There are dozens of posts on how to do this. Basically, that will turn the applet into an application, from a Java security perspective.

I'll stay in this chat ... I answered in the other one ... I have a Sony digital Handycam ... from years ago. I just got the LaCie and I think I formatted it for only to be used on my Mac ... how should I go about reformatting it to be HFS Extended like you said?

Can't parse xml from applet using dom on linux on Netscape 7 using jre 1.4.

Hi,
I can't seem to parse xml from an applet on linux on Netscape 7 using the JRE 1.4.
My code looks like the following:
StringBufferInputStream is = new StringBufferInputStream("<foo></foo>");
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try
  builder = factory.newDocumentBuilder();
  domDocument = builder.parse(is); // this line creates an exception
catch (Exception e)
  System.out.println(e);
This code works fine from an applet on windows. On linux, the error message is:
java.security.AccessControlException: access denied (java.util.PropertyPermission entityExpansionLimit read)
I've tried both JRE 1.4.0_04 and 1.4.1_03
Thanks!
Q

There's another posting about this same problem (platform unspecified), but the same error message. I was also having this problem (Windows 1.4.03) and swithced back to 1.4.01 and the problem went away. In the future, I may sign my applets to get a more generous security policy. But, I'm sure it'll be a lot of work (vs. a line of code somewhere).

Hi,
Do you mean Window Live Messenger or it's Mac equivalent MSN for Mac ?
Actually the app comes with Office
In the Microsoft Office X (2001 version) it was still called MSN Messenger
In Office 2008 it was called Microsoft Messenger.
The current one that can also be downloaded as a standalone app also comes with Office 2011 is also called Microsoft Messenger.
This is version 8 and this version is the only one that can Video Chat as a standalone app.
Version 7 required you were in a mixed environment (with PCs) connected to the correct sort of Windows Server.

Parsing XML from Socket input stream

I create a sax parser to which I send the InputStream from the socket
But my HandlerBase never gets the events. I get startDocument
but that is it, I never get any other event.
The code I have works just like expected when I make the InputStream
come from a file. The only differeence I see is that when I file is used the
InputStream is fully consumed while with the socket the InputStream
is kept open (I MUST KEEP THE SOCKET OPEN ALL THE TIME). If the parser
does not generate the events unless the InputStream is fully consumed,
isn't that against the whole idea of SAX (sax event driven) .
Has anyone been succesfull parsing XML from the InputStream of a socket?
if yes how?
I am using JAXP 1.0.1 but I can upgrade to JAXP 1.1.0
which uses SAX 2.0
Does anybody know if my needs can be met by JAXP 1.1.0?
Thanks

I did the same with client/server model.

Parse XML from CLOB field

How can I parse XML from CLOB field? I need to replace or delete the node from XML document and update the database with new XML. I am using Oracle 9i release 2.
Here is the XML. In this XML if section1 and section2 exists then I need to delete the section1 node. If section2 doesn't exist, replace section1 with section2 node.
<Document ID='2' TypeID='2'>
<Body>
<Page Name='Page1'>
<Sec ID='section1' Title='Section 1' GroupID='' />
<Sec ID='section2' Title='Section 2' GroupID='' />
</Page>
</Body>
</Document>
Please help.. Thank you..

In 9.2, you are limited into your options. Have a look into, among others, updateXML. Updating tp 10gR2 will give you more options to succeed.

How to use CrossReference and DVM in ODI &how to populate data into Xref

Can any one tell how to use Domain Value Maps and Cross Referencing in ODI?
DVM or Domain Value Map are created and used in ESB console of SOA suite.
My actual requirement is as follows:
The below steps describe loading data from ERP Application 1 to ERP Application 2.
1. The Source Application ERP APP1, populates the interface table using their native technology.
2. A job scheduler invokes the Source side ODI Package.
3. ODI then extracts the data from Source Interface table and populates the Target Interface table.
4. After populating the Target interface table the ODI populates the X-ref table with App 1 ID and generated common ID.
5. The ODI either deletes or updates the rows that were processed from the Source interface table.
6. On the Target Application ERP APP2, the native application extracts data from target interface table and populates target database there by generating ERP Application 2 ID.
7. A job scheduler on the Target application invokes the ODI package to populate the Application 2 ID onto the Xref table matching on the Common ID.
I just want to know :
1. How to populate data into the Xref table from Source datastore
2. And if data is successfully laoded from target datastore to actual base table of target then how to populate the target id into the cross reference table.

can anyone suggest me some answer, then it would be of great help?

How to parse XML in an applet

Hi all,
I am using a webrowset that gets an xml file form the server. The webrowset object has to parse this file. I have serveral questions about this and how the web browser will use an xml parser in general.
1) I need to set a whole bunch of permission just to use the parser (read/write permissions) Why do I need to do this as I am not trying to access the local resources in any way.
2) I get the following error in ie6.
ReadXml : com.sun.parser.Resolver error
In the debugger, using appletviewer, I get "no value set for parser property"
I assume that the browser is having problems locating and using the parser but cannot figure out how to solve this. I am using the java plugin so I have access to the latest version on the jvm.
Any help appreciated!
Tia

Specify the jar file containing the parser in the archive attribute
of the applet tag.
<applet
archive = "xerces.jar"

How to use functions(to_char,to_date,trim..etc) in oracle xml table

Hi I am new to oracle xml.
      In the below scenario how can use the functions like (to_char,To_date,trim..etc) In oracle xmltable."username","password" are inputs to my procedure.
SELECT *
    INTO l_username,
              l_password
    FROM xmltable('/InputParameters/ParamSet'
                    passing l_xmldoc
                    COLUMNS
                            l_username VARCHAR2(28)    path 'username',
                            l_password VARCHAR2(28)     path 'password'
and please Help how to write above with xmlquery.
Thanks,

In the same place you would for any regular SELECT statement
SELECT TO_CHAR(...),
       TO_NUMBER(...)
FROM random_table
WHERE TO_CHAR(...) = col1
   AND TO_NUMBER(...) = col2
username and password are the results of the SQL statement. I'm guessing l_xmldoc is the input? There is not need to write something so simple as XQuery so what is your larger goal? If you provide a clearer example and question, we can help you better.

Cannot parse xml from applet

I really hope that somebody can help me with this.....
I'm trying to simply parse an xml document into an applet so that the info can be used later on. I just need the tag, attribute and value.
So far, all that I can do is get the "access denied" java.util.propertypermission user.dir read error that I see tons of people complaining about. here's my code:
public StageInfo getNextStage() throws Exception
        handler = new GameXMLHandler(m_imageGiver, m_codeBase);
        spf = SAXParserFactory.newInstance();
        parser = spf.newSAXParser();
        parser.parse("Loader.xml", handler);
        return handler.getStageInfo();
    }is there a way to parse an xml file in an applet? everywhere I look, somebody is saying that it can be done, but never have they done it. I'm starting to think that there is something beyond my control that is stopping this from working. Please help!!!!

If I read your post correctly, your applet is trying to read xml file from the user's local drive? This must be done with a signed (trusted) applet. Otherwise normal run-of-the-mill applets can't access drives. Java security feature. You can use Frame, it can access local drives.

How can I export a stylesheet (either CSS or XSLT) with XML from indesign?

Hi,
I am using indesign CS4. I want to export style sheet whether it is CSS or XSLT file with xml.
I try to get it but can't.
Also the XML i am exporting does not styles that has been applied by me while creating the file in Indesign.
Please help me out by telling me the way how can i get a stylesheet and also how can I embed that style sheet with XML so that my XML file looks similiar to the indesign file.
Thanks,
Choudhary Nafees Ahmed

I am using indesign CS4. I want to export style sheet whether it is CSS or XSLT file with xml.
CSS is not an XML style sheet, it's an HTML style sheet. "Export to HTML" will export an empty stylesheet for the paragraph and character styles. ID cannot convert its (very advanced) typographic capabilities to the (very limited) CSS notation, and thus it defaults to exporting the names only.
XSLT is not an XML style sheet either; it's a transformation format (http://www.w3.org/TR/xslt).
I try to get it but can't.
Also the XML i am exporting does not styles that has been applied by me while creating the file in Indesign.
XML Export does not export anything except the items you tagged with the Auto-tag feature, or you tagged yourself. If you need your styles tagged, use Map Styles to Tags (http://www.adobe.com/accessibility/products/indesign/mapping.html).
XML has almost nothing to do with styling -- ideally, XML describes document structure while styles describe formatting.
