SAX-parser and mapping on the XI

Helllo everybody,
I'm trying to map an xml-document using the SAX-parser.
I'm reading the data using an impustream. the problem is, while testing on the XI, the following message comes :
Creating Java mapping xmlDataExchangeSAPSample/XMLValidation

the the Document ist generated :

but the parser find an empty source.
do you have an idea what could be happening here?
Kind regards

This seems that u r trying parse a file rather than valid XML document..
Usually you will notice this problem when u r trying to parse a payload which is in txt format usually when u r using File Adapter message protocol as "FILE" instead of "FCC".
Usually SAX is an API Desinged to parse Valid XML Documents only.
If you want to do manipulations on NON XML data better to use Java.io.InputStream & OutputStream.

SAX Parser and special character problem

Hi,
Could anyone help with the following problem?
Background:
1. Using a SAX Parser (Oracle Implementation) to read XML from a CLOB, convert this XML to another format to be inserted in the database.
2. Due to performance issues we parse the input stream from the CLOB.
3. For same reason, we are not using XSL.
This is the problem we face:
1. Values of some of the tags in the XML have special characters (Ex: &, <, >).
2. While using the SAX Parser, the element handler function for the SAX Parser is called by the frame work with the value of these tags broken up with each of these characters being treated as a tag delimiter.
Ex: <Description>SomeText_A & SomeText_B</Description>
is treated as SomeText_A in first call to the handler; SomeText_B in the second call.
The handler function does not get to see the "&" character.
Thus, the final conversion is
Say, <Description> is to be converted to <FreeText>
we, get <FreeText>SomeText_A</FreeText>
<FreeText>SomeText_B</FreeText>
We tried using &; but it then breaks it up into SomeText_A, & and SomeText_B.
How can we get the whole value for the <Description> tag in the characters() function in the SAXParser so that we can convert it to <FreeText>SomeText_A & SomeText_B</FreeText>.
Thanks in advance..
Chirdeep.

We already tried that..looks like the line where I mentioned that it converted the entity referece characters to an ampersand..
"We tried using <entity reference for &> but it then breaks it up into SomeText_A, & and SomeText_B."

}I am currently pulling out the package names, pulling out the classnames and then mapping these in a separate class - this works because the class and package names are declared in the same line, so if a package name appears in the package list 7 times, i know this package has 7 classes, and therefore i count the first 7 classes out of an array of all the classes and know that these are the right 7 for that package. However, the methods are a bit different:
What I would like to do is to: for every class make a hashmap which maps the class name onto an arraylist of the methods, but i think i'm getting confused with my for loops. Or even just keep a tally of how many methods each class has, then I can work it out as i did with the packages -> classes.
Does anyone know where im going wrong, or have any ideas at all?
Thank you for your time,
beccy

I don't know if stacks are specifically mentioned in any SAX documentation.
Basically, SAX sends you a stream of XML elements (open and close tags, characters, etc.), but it doesn't know anything about the underlying XML structure. You have to add that part (usually -- sometimes when writing a SAX application, you don't really care about the XML structure). XML structure is a tree.
If you've ever written a recursive function that spans a tree, you'll have an idea what to do. You can use a stack to keep track of where you are in the tree. For example, if you open tag A, then you're "in" the A element for subsequent content in that document; if you then open tag B, you're in the B element; but when you close the B tag, you need the stack to tell you that now you're back in the A element.
You may not need stacks, but it's likely. Find a good tutorial about SAX that mentions stacks and you'll be fine.

SAX parser and EntityResolver

I am using the sample SAXSample.java that comes as part of the XML parser download to parse an XML file that contains references to external entities - for example <!ENTITY E23678 SYSTEM "http://pilot/:13365">
However the SAX parser never appears to call either the EntityResolver or DTDHandler handlers even though they are set in main.
Has anyone else experienced this or have a missed something out?
Any help appreciated.

RAP and MAPs change the channel and Radio Role

I have a WLC 2504 with version AIR-CT2500-K9-7-5-102-0, LAPs are AIR-CAP2602E-A-K9
I set serveral LAPs for working in mesh mode, I set three Bridge Group Name, the first group has one Root AP and three MAPS working in channel 157, every MAP has a switch connected to its ethernet port.
the second group has 2 LAPs one Root and one MAP, all working in channel 48. The MAP is connected to a switch.
the third group has 2 LAPs, one root and one MAP, all working in channel 149. The MAP is connected to a switch.
The issue is the next:
At the beginnig every LAPs were associated to its bridge group and in the channel defined but suddenly all LAPs of group 1 move to channel 48 (second group) includind the ROOT AP. This happend after the switch that connect to the RAP was disconnect from LAN.
In order the associate once again LAPs of the first group to the channel I defined previously I connected RAP to the switch once again I notice the channel shown was 48 and in downlink role mode.I change to channel 157 reset the LAP and wait several minutes; after the first reset the RAP remains in channel
48 (it must be 157), I reset once again and wait severeal minutes. Finally the RAP was up and working in channel 157.
After this I reset the MAPs that corresponde to BGN 1 , after severasl minutes finally just one MAPs for BGN 1 was show in the correct channel and in the correct Radio role, I have to reset several times the other MAPs until they were shown in the channel I set previously and in the correct radio role.
I would like to know the reason the RAP and MAP move to a differente channel eventhough I define de Bridge Group Name in every one and the specific channel.
regards

Hi scott ,
Thanks for your explanation, very clear.
In my scenario every RAP connet to a switch where I define VLANs and specific VLANs are allow to pass. If RAP and MAP join to a different RAP (different BGN)
it will allow to pass traffic or maybe don't allow traffic I needs to . That's why I worry about the keep the MAPs join to the correct RAP and the RAP keep in the BGN and channel set previously.
is there any option to this avoid this issue?
Thanks a lot for your time
regards

Multiple columns (named the same originally) and mapped to the same lookup table are causing a Cube Build issue

Hey folks, looking for some insight here.
I've an implementation that contains some custom Enterprise columns mapped to lookup tables. In the instance I'm working with now, it looks like there was/is an issue with one of those columns. In this scenario, I have a column named
ProjectType, created initially with that name, mapped to a lookup table. This field's name was then changed to
Project Type. After that, it looks like another column was created, also called
ProjectType. So now, we have what I would have originally thought was two distinct columns, even though the names used are the same.
Below is the error we're currently getting during the Cube Build Process...

I've tried deleting the one column, but the build still gives the above error.
Any thoughts as to how the above could be resolved?

We tried taking it out of the cubes, and it builds fine. The challenge we're having is in building the cubes with that custom field "ProjectType". It's as if the cubes still hold some reference to it even when it's deleted.
Since the OLAP View ('MSP_EpmProject_OlapView_{guid}') is recreated, would it be as simple as deleting that View, and trying to recreate?

Using the SAX Parser

As I reported in this thread: Carriage Returns in XSLT output I am trying to produce a text output file with each line terminating in cr-lf (using the output from ViewObject.writeXML() passed through the XSLProcessor.processXSL() method to apply a XSLT stylesheet transformation to it), but the cr characters in the stylesheet are being converted to nl characters, so I am ending up with two nl characters at the end of each line.
I found a 2002 query (here: http://www.xslt.com/html/xsl-list/2002-04/msg00193.html) by someone with the same problem, and a reply by Steve Muench explaining it and stating that the Oracle SAX parser does not have the same problem.
So my question now is - does the SAX parser still retain cr characters (or is it too now converting them to nl) and if it does, how do I make XSLProcessor.processXSL() use it rather than the default XML parser? Can I do it from within my code, or does it need to be set in some sort of environment variable? We are on version 9.0.5.2 of JDeveloper(10g)

I've solved my problem using class RecordingInputStream that wraps the InputStream
here is the class source code:
import java.io.ByteArrayOutputStream;
import java.io.FilterInputStream;
import java.io.InputStream;
import java.io.IOException;
* @author Unknown
class RecordingInputStream extends FilterInputStream {
     protected ByteArrayOutputStream sink;
    RecordingInputStream(InputStream in) {
        this(in, new ByteArrayOutputStream());
    RecordingInputStream(InputStream in, ByteArrayOutputStream sink) {
        super(in);
        this.sink = sink;
    public synchronized int read() throws IOException {
        int i = in.read();
        sink.write(i);
        return i;
    public synchronized int read(byte[] buf, int off, int len) throws IOException {
        int l = in.read(buf, off, len);
        sink.write(buf, off, l);
        return l;
    public synchronized int read(byte[] buf) throws IOException {
        return read(buf, 0, buf.length);
    public synchronized long skip(long len) throws IOException {
        long l = 0;
        int i = 0;
        byte[] buf = new byte[1024];
        while (l < len) {
            i = read(buf, 0, (int)Math.min((long)buf.length, len - l));
            if (i == -1) break;
            l += i;
        return l;
    byte[] getBytes() {
        return sink.toByteArray();
    void resetSink() {
        sink.reset();
} Then here is the initialization before use with SAX:
this.psock = new Socket(this.profile.httpServer, Integer.parseInt(this.profile.httpPort));
this.out = new PrintWriter(this.psock.getOutputStream(), true);
this.ris=new RecordingInputStream(this.psock.getInputStream());
this.in=new BufferedReader(new InputStreamReader(this.ris));
try {
     this.parser = SAXParserFactory.newInstance().newSAXParser();
     this.parser.parse(new InputSource(this.in),new XMLCommandsHandler());
catch (IOException ioex) { }
catch (Exception ex) { }Then the handler class looks like this (it will be an inner class, so you can access ris, from the parent class):
class XMLCommandsHandler extends DefaultHandler {
     public void startDocument() throws SAXException {
          //...nothing
     public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
          // BEGIN - Synchronized logging of raw XML source code in parallel with SAX parsing :)
          byte[] bs=ris.getBytes();
          logger.warn(new String(bs));
          ris.resetSink();
          // End logging
          if ("expectedTagThatTriggersMeToDoSomething".equals(qName)) {
               //...Do smth.

JDBC receiver adapter - Error processing request in sax parser

Hello,
I want to INSERT idoc data via JDBC adapter into a MS SQL database. After digging through SAP Help, numerous blogs and forum discussions on SDN and even posting an OSS message I still get the same error:
'Error: TransformException error in xml processor class: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)'
When testing my mapping in the Integration Repository the resulting XML message is:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Employee xmlns:ns0="http://prodrive.nl/xi/HRMasterdata/HRMD_A_2_d_bcommerp">
   <STATEMENT>
      <T_PD_Employees action="INSERT">
         <access>
            <KeyTag>00088888</KeyTag>
            <PerNo>00088888</PerNo>
         </access>
      </T_PD_Employees>
   </STATEMENT>
</ns0:Employee>
The connection to the database is fine, Sender adapter with a SELECT * works perfect.
Can anyone help me solve this problem? I'm lost.
Best regards,
Roelof Jan Bouwknegt

Hi Bhavesh,
I have tried out the change you suggested. Without success. Message I get back is
- 2006-12-28 10:34:08 CET: Error: TransformException error in xml processor class: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)

         </ACCESS>
      </T_PD_Employees>
   </STATEMENT>
</ns0:Employee>
Somehow the SAX parser doesn't like the result of my mapping. Maybe there is something wrong with the structure cardinality. Let me describe what I have built:
XSD:
WA_T_PD_Employees - Complex Type
> STATEMENT - Element - Occurence = 1
>> T_PD_Employees - Element - Occurence = 1
>>> STATEMENT - Attribute - Occurence = optional
>>> access - Element - Occurence = 1..Unbounded
Best regards Roelof Jan and thanks for your quick response

How to deal with empty tags in a SAX Parser

Hi,
I hope someone can help me with the problem I am having!
Basically, I have written an xml-editor application. When an XML file is selected, I parse the file with a SAX parser and save the start and end locations of all the tags and character data. This enables me to display the xml file with the tags all nicely formatted with pretty colours. Truly it is a Joy To Behold. However, I have a problem with tags in this form:
<package name="boo"/>
because the SAX parser treats them like this:
<package name = boo>
</package>
for various complex reasons the latter is unaccetable so my question is: Is there some fiendishly clever method to detect tags of this type as they occur, so that I can treat them accordingly?
Thanks,
Chris

I have spent some time on googling for code doing this, but found nothing better, than I had to write in by myself.
So, it would be something like this. Enjoy :)

XML - SAX Parsing Question

Hi,
I am parsing XML using SAX parser and fill the values into the HashTable ( like Key value pair ).. so i can get the vaues for a particular key using hash get function.
For the following XML. There are 2 "subscriberNumber" attribute, one is under "sn:Subscriber" and the another is under "sn:SubscriberChange".
I can able to put this values in hash table and when i print the Hash table it is printing as sn:subscriberNumber=[1234567890, 1234567890] .. But how will i know which one is from "sn:Subscriber" and which is from "sn:SubscriberChange"
This is the XML :
<sn:SubscriberNotification>
<sn:notificationSubType>1120</sn:notificationSubType>
<sn:Subscriber>
     <cng:PaymentType>PostPaid</cng:PaymentType>
     <sn:subscriberNumber>1234567890</sn:subscriberNumber>
</sn:Subscriber>
<sn:SubscriberChange>
     <sn:subscriberNumber>1234567890</sn:subscriberNumber>
</sn:SubscriberChange>
</sn:SubscriberNotification>
Any suggestion and pointers are really helpful
Thanks,
-Raj..

Try something like this:
import java.util.Stack;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
class MyHandler extends DefaultHandler {
    Stack openTags = new Stack();
    public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
        if (qName.equals("sn:subscriberNumber")) {
            String parentTag = (String)openTags.peek();
            System.out.println("Parent tag of this <sn:subscriberNumber> is : <" + parentTag + ">");
        openTags.push(qName);
    public void endElement(String uri, String localName, String qName) throws SAXException {
        openTags.pop();
}Regards

Problem in parsing an XML using SAX parser

Hai All,
I have got a problem in parsing an XML using SAX parser.
I have an XML (sample below) which need to be parsed
<line-items>
<item num="1">
     <part-number>PN1234</part-number>
     <quantity uom="ea">10</quantity>
     <lpn>LPN1060</lpn>
     <reference num="1">Line ref 1</reference>
     <reference num="2">Line ref 2</reference>
     <reference num="3">Line ref 3</reference>
</item>
<item num="2">
     <part-number>PN1527</part-number>
     <quantity uom="lbs">5</quantity>
     <lpn>LPN2152</lpn>
     <reference num="1">Line ref 1</reference>
     <reference num="2">Line ref 2</reference>
     <reference num="3">Line ref 3</reference>
</item>
<item num="n">
</item>
</line-items>
There can be any number of items( 1 to n). I need to parse these
item values using SAX parser and invoke a stored procedure for
each item with its
values(partnumber,qty,lpn,refnum1,refnum2,refnum3).
Suppose if there are 100 items, i need to invoke the stored
procedure sp1() 100 times for each item.
I need to invoke the stored procedure in endDocument() method of
SAX event handler and not in endelement() method.
What is the best way to store those values and invoke the stored
procedure in enddocument() method.
Any help would br greatly appreciated.
Thanks in advance
Pooja.

VO or ValueObject is a trendy new name for Beans.
So just create an item class with variables for each of the sub elements.
<item>
<part-number>PN1234</part-number>
<quantity uom="ea">10</quantity>
<lpn>LPN1060</lpn>
<reference num="1">Line ref 1</reference>
<reference num="2">Line ref 2</reference>
<reference num="3">Line ref 3</reference>
</item>
public class ItemVO
String partNumber;
int quantity;
String quantityType;
String lpn;
List references = new ArrayList();
* @return Returns the lpn.
public String getLpn()
return this.lpn;
* @param lpn The lpn to set.
public void setLpn(String lpn)
this.lpn = lpn;
* @return Returns the partNumber.
public String getPartNumber()
return this.partNumber;
* @param partNumber The partNumber to set.
public void setPartNumber(String partNumber)
this.partNumber = partNumber;
* @return Returns the quantity.
public int getQuantity()
return this.quantity;
* @param quantity The quantity to set.
public void setQuantity(int quantity)
this.quantity = quantity;
* @return Returns the quantityType.
public String getQuantityType()
return this.quantityType;
* @param quantityType The quantityType to set.
public void setQuantityType(String quantityType)
this.quantityType = quantityType;
* @return Returns the references.
public List getReferences()
return this.references;
* @param references The references to set.
public void setReferences(List references)
this.references = references;

SAX Parser in OC4J

I'm trying to read a XML file in an EJB using a SAX parser.
I tried the following statement to create the reader
XMLReader xr = XMLReaderFactory.createXMLReader("oracle.xml.parser.v2.SAXParser");
but I obtain the following exception:
java.lang.ClassNotFoundException: oracle.xml.parser.v2.SAXParser
at org.xml.sax.helpers.XMLReaderFactory.createXMLReader(XMLReaderFactory.java:118)
The same works correctly from a command line application outside OC4J.
Is there another SAX Parser I can use in OC4J?
Andrea Mattioli

I'm also seeing the a similar problem trying to get my EJB to parse SAX using the Xerces parser. If I do
XMLReader myReader = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
and place xerces.jar into $(OC4J_INSTALL_ROOT)\j2ee\home\lib then at runtime I get
java.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXParser
This is despite the fact that calling Class.forName() on the same class name works fine. Setting the system property org.xml.sax.driver and calling createXMLReader with no parameters results in the same error.
I can force use of the Xerces SAX parser by bypassing the factory and just calling
XMLReader myReader = new org.apache.xerces.parsers.SAXParser();
but that seems a tad hacky and I don't want to hardwire SAX parser implementation choice into my code.
Is this a known bug?
Also which parser is getting used by default in OC4J i.e. if I don't set org.xml.sax.driver and use the no parameters variant of createXMLReader()?
Thanks
Alan

SAX parser getValue() method

All,
Whever i get the attribute value using getValue() method , it returns me the result with the lower case string
for example if i have something like this
<input label="Last Name:" />
and i try to get the attribute value of label
String label = attrs.getValue("label");
The result will be
label = "last name"
It doesnot adhere with the case (it returns the value by converting it into lower case)
Is it something that i am doing wrong , or its the way SAX parser internally does it.
I am using the SAX parser which comes with the BlackBerry JDE.
Any answers , pointers will be helpful

Never mind , my input to the SAX parser itself is somehow getting all lower case.
Thanks!
