SAX mapping
Hi,
I have Java SAX mapping for IDOC-to-JDBC scenario. Sometimes it happens that, XI starts to create first XML SQL message, then in one moment stops(this XML hasn't right structure) and starts with second. With second, XI ends OK, but this has, XML syntactically, OK structure, and it can not be parsed to SQL. JDBC says:
Error while parsing or executing XML-SQL document: ERROR occured parsing request:com.sap.engine.lib.xml.parser.NestedSAXParserException: Fatal Error: com.sap.engine.lib.xml.parser.ParserException: XML Declaration not allowed here.(:main:, row:2, col:6)(:main:, row=2, col=6) -> com.sap.engine.lib.xml.parser.ParserException: XML Declaration not allowed here.(:main:, row:2, col:6)
This is some mix of two messages that should be mapped separatly. has anybody any idea?
thx

Hi Mario,
This SAX Parser exception generally occurs when some condition is not being satisfied by the message payload when it is being parsed through the SAX Parser..for eg. if some tag in your message has data of greater legth than is specified in the condition in IR it throws a saxparser exception.
A mapping error is a non-fatal error that occurs during the mapping process.
The fatal errors are errors such as IOException that interrupt the mapping process and the exception is thrown by the mapping utility.
For more sax parser exception please refer:
http://java.sun.com/j2se/1.5.0/docs/api/org/xml/sax/helpers/DefaultHandler.html
Hope this will be of help for you.

Shibani

JAVA Sax mapping replaces &_amp; with & causing mapping to fail
Hi all,
I have the following mapping scenario:
Source XML -> Java Sax Mapping -> Graphical Mapping -> Target structure
The source XML is valid and caters for special characters like & which appear as &_amp; in the XML (ignore the underscore _ without it the editor strips the amp;, isn't that ironic!).
The second step of the interface mapping, which is the graphical map, is failing. It seems that the Java Sax mapping is replacing &_amp; with & in the XML, which is then causing the graphical map to fail as it cannot handle the special character &.
Is there anyway I can prevent the Java Sax mapping from changing & to &
Or is the only solution for me to write extra code in the Java map to convert & back to &_amp; before passing to the second mapping step????
Any help appreciated.

Use this in your source xml file for '&' ->"&_amp;" remove the underscore

Hi, I'm using SAX mapping, but in case that some field has "&" as content, for example company name,
public void characters(char buf[], int offset, int len)
throws SAXException {
String s = new String(buf, offset, len);
for string "name m&s" returns only "s". It loops(splits this string into 3) trough:
1. "name m"
2. "&"
3. "s"
and in this case, I get only "s" what is completely wrong. How to avoid that?
br
marioHi
Can you convert the character & to "& a m p ;" whithout white spaces?
"& a m p ;" is the correct value for some XML parsers, or try to use other character set.

Hi Experts,
as part of my diploma-thesis I have to write a java SAX-Mapping, which mapps the following incoming message:
mt_MappingOUT
set
set_Element_01
set_Element_02
set_Element_03
set_Element_10
to the following outgoinig message:
mt_MappingIN
TABLE
item
item_FIELD_01
item_FIELD_10
I develped the following code, which unfortunately results in "XML is not well defined" while testing. Unfortunately I cannot find the problem. So I hope someone of you can have a look an will have an idea.

Dear all,
I am developing a EJB as the adapter module for the data validaion of the sender message on XI.
Because of the limit of accessing external website I can't implement the validation by parsing the payload
against the external XSD.
Therefore I am trying to implement the validation by parsing the payload against the internal DTD instead of the external XSD or the external DTD.
Please advise me how to convert the external XSD as the internal DTD into the payload before the
payload is parsed.
Thanks & Regards,
RedAlso you can find sample code on the site below.
Please eliminate unused code and then use it.
Also do the required System property setting which is already there in the code.
(And do clear it after setting & using the system property)

PS: The code is using SAX mapping to create the required source structure in message mapping of XI

Hi,
I'm using SAX Java mapping in one scenario. Problem is when I get some Croatina characters, like Đ or u0160,
output XML is not valid. XML Spy complains, IE complains and so on. Customer is sure that data ( XML in CLOB field in Oracle DB) is UTF-8? What could be a problem?
What I'm doing is reading entire XML into string with help of BufferedReader, then do some manipulation and write String into byte array with:
byte[] bytes = file.toString().getBytes("UTF-8");
saxParser.parse(new ByteArrayInputStream(bytes), handler);
and then of course parse XML. readLine method reads data and problematic is "�" - 0 - 0xC490.
For this character XML Spy doesn't complain, IE also. After conversion, this character looks like "Ä?" - 0xC43F, and this is not good any more. Why?Hi Stefan,
I've finally done it. Code as foollws:
public void execute(InputStream in, OutputStream out)
throws com.sap.aii.mapping.api.StreamTransformationException {
DefaultHandler handler = this;
SAXParserFactory factory = SAXParserFactory.newInstance();
try {
SAXParser saxParser = factory.newSAXParser();
fStreamOut = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
encoding = "UTF-8";
if (map != null) {
mappingTrace = (MappingTrace) map
.get(StreamTransformationConstants.MAPPING_TRACE);
InputStreamReader is = new InputStreamReader(in, "UTF8");
BufferedReader reader = new BufferedReader(is);
StringBuffer file = new StringBuffer();
String line = new String();
try {
while ((line = reader.readLine()) != null) {
file.append(line);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
Date d4 = new Date();
file = replaceREGEX(
"<\\?xml version=\"1\\.0\" encoding=\"UTF-8\"\\?>", "",
file);
char[] cArray = file.toString().toCharArray();
Date filedat = new Date();;
SimpleDateFormat df = new SimpleDateFormat("yyyyMMdd_HHmmss_SSS");
String fName = df.format(filedat) + "_El_Invoice.xml";
Writer out1 = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream(fName), "UTF8"));
try {
out1.write(file.toString().toCharArray());
out1.close();
} catch (UnsupportedEncodingException e) {
} catch (IOException e) {
saxParser.parse(fName, handler);
File outFile = new File(fName);
outFile.delete();
} catch (Throwable t) {
if (mappingTrace != null) {
mappingTrace.addInfo(t.toString());
t.printStackTrace();
problem was also in method for writing in output stream, so I've changed it:
private void printOutPut(String sOP) {
try {
// fStreamOut.write(sOP.getBytes());
fStreamOut.write(sOP);
} catch (IOException e) {
e.notify(); -
Issue with mapping XML to Java using SAX API
I am using SAX API to Map XML Documents To Java. Is it possible to differentiate the elements based on the attribute rather than localname or element name in SAX API? because I am having the below xml structure. In SAX API we are processing the element values based on start/End Element name.

JAVA Mapping with SAX: Illegal character exception &
Hi everybody,
I use a SAX JAVA Mapping. It throws an error cause the xml that is parsed has a
&
like in
<D_3036>Company & Co. KG</D_3036>
Does anybody know how to solve the problem?
I do not want to replace the
&
Are there special settings/properties for the handler/parser?
Thanks
Regards
MarioHi all,
thanks for your comments and suggestions. The error was not cause by the problem I describes.
FYI:
If there is an ampersand in the middle of a string, than the standard method
characters
in the handler is called three times!
This let me asume the ampersand was the error.

In Java Mapping Whether to SAX or DOM ?
While implementing Java Mapping which of the following SAX , DOM parsers is the most efficient way to implement it.
I mean considering the voulume of data in the XML format is large which usage will give me most optimal performance .
It would be nice if someone could give a sample most optimal java code using JAXP where input stream is read and after processing written to output stream.
regards
Nilesh Taunk.Hi Nilesh,
>>>While implementing Java Mapping which of the following SAX , DOM parsers is the most efficient way to implement it.
there's no one good answer fot this question
except: it depends:)
SAX and DOM are a little different parsers
so it depends what will your java mapping
have to do: if it will change the
structure or maybe it will only change a few tags,
or maybe it will do something else
have a look at the page below to read a simple
comparision between SAX and DOM
http://www.scit.wlv.ac.uk/~jphb/cp2101/week4/XML_Parsing.html
or this thread:
http://www.biglist.com/lists/xsl-list/archives/200301/msg01318.html
they will give you some idea which one to choose
depending on your requirements
BTW
remember use java mappings only
if you cannot use graphical mapping (very easy debugging)
and if your document cannot be parsed (maybe huge documents)
with XSLT which is supported by many graphilal tools

JAVA mapping using SAX parser adds extra tags
Hi,
We are using java mapping using a SAX parser.It works well in standalone application ie it parses correctly and gets our desired xml structure and the xml is well formed too but when we import it in XI as a jar file it does not throw any errors but adds extra start tags, as a result the output xml is not well formed.XI is adding extra start tags.
If any one else has faced a similar situation please help.
Regards,
Anirban.Hi Roberto,
Thank you for the response.
As I said, it doesnt throw any error. It is working perfectly in standalone application. But when we deploy it to XI Server, it is not forming the well formed XML. We too are puzzled by this situation.
Okay, i will explain my scenario here.
The following is my input XML to the java pgm..
<Header>
</Header>
<Body>
</Body>
<SubBody1>
</SubBody1>
<SubBody2>
</SubBody2>
<SubBody3>
</SubBody3>
<SubBody4>
</SubBody4>
<Trail>
</Trail>
The desired output is
<Header>
<Body>
<NameChanged1>
<NameChanged2>
<SubBody3>
<SubBody4>
</SubBody4>
</SubBody3>
</NameChanged2>
</NameChanged1>
<Trail>
</Trail>
Just look at the SubBody2 and SubBody1 node, its tag name has been changed in the output XML. Thats y i have decided to use java mapping instead of message mapping.
I have developed the code for everything, i.e for changing the tag name and for forming the nested xml and it is working fine as a standalone application. But while deploying it to XI, the output is not well formed. I dont know the reason for it. Even I have checked the cardinality of the output Data types, that I have created. Its perfectly okay with all.
Any Ideas???

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 :

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.

Hi,
im using java mapping for complex IDOC structure. If I run program localy, it works great, but when XI runs mapping, I have problems with xml file, some elements are not there ?! I don't know why it happens.....i said that i'm using complex logic, and therefore I'm using complex IF statments to produce segment in IDOC. I have noticed that there is a problem, because when I switch off IF, everything is fine???? any idea??
thx marioHi,
Do you have nested 'if' statements? Is it possible you could be experiencing a "dangling else" problem?

** How to use TO_DATE function in Stored Proc. for JDBC in ABAP-XSL mapping
Hi friends,
I use ABAP-XSL mapping to insert records in Oracle table. My Sender is File and receiver is JDBC. We use Oracle 10g database. All fields in table are VARCHAR2 except one field; this is having type 'DATE'.
I use Stored procedure to update the records in table. I have converted my string into date using the Oracle TO_DATE function. But, when I use this format, it throws an error in the Receiver CC. (But, the message is processed successfully in SXMB_MONI).
The input format I formed like below:
<X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">
Value in Payload is like below.
<X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">TO_DATE('18-11-1991','DD-MM-YYYY')</X_EMP_START_DT>
Error in CC comes as below:
Error processing request in sax parser: Error when executing statement for table/stored proc. 'SP_EMP_DETAILS' (structure 'STATEMENT'): java.lang.NumberFormatException: For input string: "TO_DATE('18"
Friends, I have tried, but unable to find the correct solution to insert.
Kindly help me to solve this issue.
Kind Regards,
Jegathees P.
(But, the same is working fine if we use direct method in ABAP-XSL ie. not thru Stored Procedure)Hi Sinha,
Thanks for your reply.
I used the syntax
<xsl:call-template name="date:format-date">
<xsl:with-param name="date-time" select="string" />
<xsl:with-param name="pattern" select="string" />
</xsl:call-template>
in my Abap XSL. But, its not working correctly. The problem is 'href' function to import "date.xsl" in my XSLT is not able to do that. The system throws an error. Moreover, it is not able to write the command 'extension-element-prefixes' in my <xsl:stylesheet namespace>
May be I am not able to understand how to use this.
Anyway, I solved this problem by handling date conversion inside Oracle Stored Procedure. Now, its working fine.
Thank you.
