Invalid XML character in castor XML
I am using castor API for converting an object into XML. When I marshal the object, following exception occur:
java.io.IOException: The character '' is an invalid XML character
at org.apache.xml.serialize.BaseMarkupSerializer.characters(Unknown Source)
at org.exolab.castor.xml.Marshaller.marshal(Unknown Source)
at org.exolab.castor.xml.Marshaller.marshal(Unknown Source)
at org.exolab.castor.xml.Marshaller.marshal(Unknown Source)
Following is the code snippet which I am using:
StringWriter writer = new StringWriter(500);
Marshaller marshal = new Marshaller(writer);
marshal.setEncoding("windows-1251"); //I have tried all these encodings as well: UTF-8, UTF-7, ASCII, ISO-8859-1, ISO-8859-5, windows-1251
//marshal.marshal(token, writer); // This is commented, since the encoding is not applied if I use this method, next statement works fine
marshal.marshal(token);Here, token is the object which I am trying to marshal. I have tried different encodings, but the problem is not resolved. Could anyone help?
Castor reference:
[http://www.castor.org/xml-framework.html ]
Do you want this encoding to be reversible? For example, that character \u001b which is in the string. You have to represent it by something different in your XML. If you want to get the same thing back when you convert your XML back into Java, then you can't just translate that character into an existing character, because then you have lost information. You have to translate it into some special series of codes. And then when you convert the XML back, you have to recognize that special series of codes and convert that into the \u001b character.
So yeah, you could write your own custom encoding which did that. I'm not aware of any existing software that does that; it wouldn't be very useful, because it would result in XML documents which used non-standard encodings and hence couldn't be sent to anybody else.

Getting invalid xml character while marshalling
Hi
I have a text which contains all characters including some special chars.I am replacing the html codes for &,>,<,\," characters. I am building the xml file and trying to marshall it. But i am getting "The character '' is an invalid XML character". I am using castor-0.9.6.jar. Can any one tell me how can i handle special chars like � is easy way rather than repacing each and every character.
Please let me know why i am getting the above error (is the special char end of file char. actually i am reating from string not from file).
Thanks & Regards,
PrasanthAs a guess because you are treating CDATA as meaning the same as 'binary' which it isn't. The characters in CDATA still must be valid XML characters.
If you want binary data then base64 encode it and put that in the document - and you won't need CDATA at all then, it will just be regular element text. -

Error in moni as invalid XML character (Unicode: 0x16) was found
Hello Experts,
I am facing an issue in Production interface is Proxy - -> JDBC data is passing in ECC successfully in PI moni it is showing error
as Runtime Exception when executing application mapping program com/sap/xi/tf/_MaterialPlantFromSAP_to_MaterialPlantToDYNAMINE_; Details: com.sap.aii.utilxi.misc.api.BaseRuntimeException; An invalid XML character (Unicode: 0x16) was found in the element content of the document.
when i try to open the payload it is showing data is too long when i click on open screen is getting hang showing as not responding.I have checked in the ECC it is also showing data is too long when i click on open after 1 min payload is opening when i try to copy the payload and paste in Message mapping test tab again screen is getting hanging when i try to test with 20 or 30 records in Mapping it going through.
I have downloaded that XML file from ECC moni it is 8.83 MB .
PI can process this huge file ? please suggest me how to pass data in chunks .And also i am not understanding error is due to Payload has not correct data or Payload is huge.
Please throw some light on the issue any help is highly appreciated.

Praveen ReddyHi Praveen,
you need a HEX editor. Please download one from this link
http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm
Here in the editor search for the HEX value 0X16 and see the corrosponding charcater in payload.
Try getting rid of the character before it reaches Integrtaion engine possibly with java mapping.

An invalid XML character (Unicode: 0x0) was found in the prolog of the docu
Hi folks,
I'm using the SAX parser to parse a small xml file. If I use that file in IE, there its parsing correctly and displaying the xml in the tree structure.
But in my Java code its throwing
org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x0) was found in the prolog of the document.
The xml parsing code of my program is
XMLReader parser = XMLReaderFactory.createXMLReader(
"org.apache.xerces.parsers.SAXParser");
HelpPartHandler hp = new HelpPartHandler();
parser.setContentHandler(hp);
RandomAccessFile raf = new RandomAccessFile("sample.xml","r");
byte Contents[] = new byte[(int)raf.length()];
StringReader sr = new StringReader(new String(Contents));
InputSource is = new InputSource(sr);
parser.parse(is);
The xml file is
<?xml version="1.0"?>
<ROOT>
<NODE> Java </NODE>
</ROOT>
Please let me know the mistakes what I have done. Looking for the reply.
Thanks in Advance
PrabuThe message seems clear to me. Your document contains a null character, which is not valid in an XML document. Take it out of the document, and change whatever produced the document to not put it there. (I hope you don't consider Microsoft software to be standards-compliant.)

Invalid XML character in web service answer of MS Exchange
Hello Forum!
We have to look up contacts in the global address list of a Microsoft Exchange server.
The current solution uses the web services that have been introduced in version 2007 of MS Exchange.
Unfortunately some records returned by the MS Server cause a javax.xml.stream.XMLStreamException. The Exception
tells us that a parser error occurred. The Exception says:
Message: Character reference "" is an invalid XML character.
The Java classes used for accessing the Exchange web services are generated using the jaxws plugin and the application
is running on the Glassfish application server v2 ur1.
The only solution we can think of right now is to access the XML stream returned by the Exchange server before it is handed over
to the parser in order to replace the invalid characters.
Can anyone point me to some documentation or give me an example of how to intercept the XML parsing process used by the jaxws
component?
Any other ideas for a solution are of course also appreciated.
Thanks for your help in advance,

In addition to that MS is not very responsive when it comes to Java questions.Yes, but "Your software is producing malformed XML" is not a Java question.
I can imagine that filtering the stream isn't very easy - are you able to provide some links to additional
information that can help us getting started in that direction?A subclass of FilterInputStream whose read() method calls the superclass's read() method a second time when the input is between 0 and 19, or whatever are the invalid XML characters? -
Hi,

RFC to JDBC - Character reference invalid XML character
Dear all Gurus,
I have developed a RFC to JDBC scenareo and when trying to pass data i get a error saying (sxmb_moni) - "Runtime exception occurred during application mapping com/sap/xi/tf/_MM_de_cx_xd01_va01_2_Siebel_; com.sap.aii.utilxi.misc.api.BaseRuntimeException:Character reference ("&#00") is an invalid XML character"
I dont pass any blank values here & tried to pass one value(there is only one not null value in the table) to the Oracle Table again above error accurs.Hi,
You can solve this problem performing following steps in your ECC system:
1. Go to transaction sm59 and locate the RFC Destination for your PI system. Double-click to open it.
2. Perform a "Unicode Test" using the button in top menu or pressing Ctrl+F5. The result will either say "Target is a unicode system" or "is NOT a unicode system".
3. Go to "MDMP & Unicode" tab page and set Non-Unicode or Unicode connection mode, depending on the result of your test in step 2.
Alternatively, you can also find your Sender Communication Channel in PI's ID and set the Unicode indicator there - it should be consistent with what is set in sm59 in your backend system.
Hope this helps,

Fix Invalid XML character (Unicode: 0x1c) before xml data parsing
How to fix the error :- "An invalid XML character (Unicode: 0x1c) was found in the element content of the document."
This error message is generated before parsing of xml data.
So how to filter the unwanted characters like 0x1c during XML file generation?ASCII has nothing to do with it. XML is a text format and so an XML file may only include text characters. 0x7 isn't a text character, it's a control character, and it isn't allowed to occur in an XML file.
As for how to identify which character is causing the problem, the error message tells you that. -
Handle invalid xml character while serializing
I have requirement where I need to serialize a document which contains a string like "ンᅧᅭ%ンᅨ &". While serializing it throws the following exception
java.io.IOException: The character ' ' is an invalid XML character
Is there a way we can serialize this String as is with any workaround.
StringWriter stringOut = new StringWriter();
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
Element rootElement = doc.createElement("company");
doc.appendChild(rootElement);
String xml = "ンᅧᅭ%ンᅨ &";
//String xml = "ンᅧᅭ%ンᅨ &";
Element junk = doc.createElement("replyToQ");
junk.appendChild(doc.createCDATASection(xml));
//junk.appendChild(doc.createTextNode(stripNonValidXMLCharacters(xml)));
rootElement.appendChild(junk);
//org.w3c.dom.Document doc = this.toDOM();
//Serialize DOM
OutputFormat format = new OutputFormat(doc,"UTF-8",true);
format.setIndenting(false);
format.setLineSeparator("");
format.setPreserveSpace(true);
format.setOmitXMLDeclaration(false);
XMLSerializer serial = new XMLSerializer( stringOut, format );
// As a DOM Serializer
serial.asDOMSerializer();
serial.serialize( doc.getDocumentElement() );As a guess because you are treating CDATA as meaning the same as 'binary' which it isn't. The characters in CDATA still must be valid XML characters.

Invalid XML Character from Jarred file

While experimenting, I found the following:

</foos>If the line between the two foo elements were removed, the jar one worked with my original code. However, with the input stream it seems to not care. I had build the XML file on a Solaris box using 'vi' and the application was also run from solaris. -

Mapping error: Character reference "&# 00" is an invalid XML character
Hi All,
Iam performing the RFC(R/3) -> PI(7.1) -> SOAP (third party software) ; Synchronous scenario.
The messages are reaching the PI server , but the a mapping errors is occurring due to dummy characters ""& #00" been sent to the XI system.
Is this due to the R/3 sending the invalid characters or these been generated in PI system. Would you suggest any notes,patches to resolve the issue?
