hi ther,
I am trying to extract the xml from the mbelement but i fails to do so.
is there any way that we can extract the xml from the mbelement?
here is my code:
| Code: |
public void evaluate(MbMessageAssembly contact admin) throws MbException {
MbOutputTerminal out = getOutputTerminal("out");
MbOutputTerminal alt = getOutputTerminal("alternate");
MbMessage inMessage = contact admin.getMessage();
// create new message
MbMessage outMessage = new MbMessage();
MbMessageAssembly outAssembly = new MbMessageAssembly(contact admin,
outMessage);
try {
// optionally copy message headers
copyMessageHeaders(inMessage, outMessage);
// ----------------------------------------------------------
// Add user code below
try {
MbElement xml = inMessage.getRootElement().getLastChild().getFirstChild();
MbElement outRoot = outMessage.getRootElement();
MbElement outBody = outRoot.createElementAsLastChild("XMLNSC");
outBody.addAsLastChild(xml.copy());
MbMessage msg = outAssembly.getMessage();
// converting the msg to bitstream
byte[] bitstream = msg.getBuffer();
String myfile = "C:/sample.txt";
// converting bitstream back to string
String b = bitstream.toString();
FileOutputStream outputStream = new FileOutputStream(myfile);
// trying to print bitstream
outputStream.write(bitstream);
outputStream.close();
PrintWriter pw = new PrintWriter(new FileWriter("C:/sample.txt"));
// trying to print string assigned to variable b
pw.print(b);
pw.print(' ');
pw.println();
pw.close();
}
catch (Throwable e) {
System.err.println(e);
}
// End of user code
// ----------------------------------------------------------
// The following should only be changed
// if not propagating message to the 'out' terminal
out.propagate(outAssembly);
} finally {
// clear the outMessage even if there's an exception
outMessage.clearMessage();
}
}

in the above code i am trying to convert the mbelement to bitstream first and then string so that i can use it to pass to other java application but the conversion to string from the bitstream fails.
to be clear on the whole i am trying to extract either xml or the string(full inputbody) from the input message. so that i can pass it to other method defined in other java program but it fails.
note: i am able to print the bitstream perrfectly to a file but when i convert it to a string(bitstream) it doesn't.

| Of course getBuffer() is the wrong method to use in the first place. |

Try to use something like
| Code: |
byte [] msgAsBytes = inMessage.getRootElement().getLastChild().toBitstream(null,null,null,0,ccsid,0);
String msgAsText = new String(msgAsBytes); |
where ccsid is the proper ccsid code. |

thanks bartez your suggestion worked!!
now i have another issue how can i convert a string into a mbelement i mean how to i put the sting into a mbelement.
DETAils:
I call a java method with the above converted string and it then sends the response back which is again in the string format now i need to put this string(which is a xml in string format ex:"<xml></xml>") back into the Mbelement to propagate to output terminal.Any ideas???

Why do you even bother to serialize into an xml string that you would have to parse again? Are you changing parser and deem this faster than just copying the tree, or less complicated (xmlns to xmlnsc)? What does the manual say? Have you checked what it says about copying the tree? Have you checked the examples? Have you looked at how they copied the headers?
Help yourself some and  the manuals, its all there 
Have fun

hello fjb_saper as i said before the need to serialize the mbelement to string is becoz there is a functionality written in java program where it accepts the argument in the form of xml string and then returns a xml string which i need to convert back to mbelement to send to output terminal.. |

I believe both the serialization and the parsing of such a string have been talked about on the forum and are documented in the infocenter.
The search button is your friend.
