This works on the message tree only:
byte [] msgAsBytes = outMessage.getRootElement().getLastChild().toBitstream(null,null,null,0,0,0);
String msgAsText = new String(msgAsBytes);
messageAug.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"EVA", msgAsText);
So to get environment tree into a string I wrote this:
MbMessage environment = contact admin.getGlobalEnvironment();
MbElement variables = environment.getRootElement().getFirstChild();
MbElement variablesPosition = variables.getFirstChild();
StringBuffer strBufferEnv = new StringBuffer();
for (int s = 0; variablesPosition != null; s++) {
strBufferEnv.append("<");
strBufferEnv.append(variablesPosition.getName());
strBufferEnv.append(">");
if (variablesPosition.getValueAsString() != null) {
strBufferEnv.append(variablesPosition.getValueAsString());
}
else{
MbElement variablesPosition2 = variablesPosition.getFirstChild();
if (variablesPosition2 != null){
for (int t = 0; variablesPosition2 != null; t++) {
strBufferEnv.append("<");
strBufferEnv.append(variablesPosition2.getName());
strBufferEnv.append(">");
if (variablesPosition2.getValueAsString() != null) {
strBufferEnv.append(variablesPosition2.getValueAsString());
}
else{
MbElement variablesPosition3 = variablesPosition2.getFirstChild();
if (variablesPosition3 != null){
for (int u = 0; variablesPosition3 != null; u++) {
strBufferEnv.append("<");
strBufferEnv.append(variablesPosition3.getName());
strBufferEnv.append(">");
if (variablesPosition3.getValueAsString() != null) {
strBufferEnv.append(variablesPosition3.getValueAsString());
}
else{
MbElement variablesPosition4 = variablesPosition3.getFirstChild();
if (variablesPosition4 != null){
for (int v = 0; variablesPosition4 != null; v++) {
strBufferEnv.append("<");
strBufferEnv.append(variablesPosition4.getName());
strBufferEnv.append(">");
if (variablesPosition4.getValueAsString() != null) {
strBufferEnv.append(variablesPosition4.getValueAsString());
}
strBufferEnv.append ("</");
strBufferEnv.append(variablesPosition4.getName());
strBufferEnv.append(">");
variablesPosition4 = variablesPosition4.getNextSibling();
}
}
}
strBufferEnv.append ("</");
strBufferEnv.append(variablesPosition3.getName());
strBufferEnv.append(">");
variablesPosition3 = variablesPosition3.getNextSibling();
}
}
}
strBufferEnv.append ("</");
strBufferEnv.append(variablesPosition2.getName());
strBufferEnv.append(">");
variablesPosition2 = variablesPosition2.getNextSibling();
}
}
}
strBufferEnv.append ("</");
strBufferEnv.append(variablesPosition.getName());
strBufferEnv.append(">");
variablesPosition = variablesPosition.getNextSibling();
}
String Eva2 = strBufferEnv.toString();
messageAug.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"EVA2", Eva2);
Which works just fine...but Im wondering if there is any better way to do this in JCN ? |

How well this works depends on the message ccsid, the platform's default charset, and whether the message contains multi-byte characters.

Use the ESQL CREATE statement, (or similar Java MbElement.createElement methods), to associate a new element with a parser, so that the toBitstream() method can use the parser to serialize the element and its children. |

Hi,
I think you could try to create branch for example to LocalEnvironment with XMLNSC domain. Copy your sub tree there and serialise that to bytes and convert it to string as you have done with root -object.

Followed your advice and used it on serializing exception tree as well:
String text =
//(String)assembly.getExceptionList().evaluateXPath("string(//ParserException/Text)");
(String)assembly.getExceptionList().evaluateXPath("string(//EvaException/Text)");
if (text.equals("")){
MbMessage exceptionTree = assembly.getExceptionList();
MbElement ExceptionTreeList = exceptionTree.getRootElement();
//
MbMessage localEnvironment = assembly.getLocalEnvironment();
MbElement xmlRoot =
localEnvironment.getRootElement().createElementAsLastChild(MbXMLNSC.PARSER_NAME);
MbElement xmlExceptionTreeList = xmlRoot.createElementAsLastChild(MbElement.TYPE_NAME,
"xmlExceptionTreeList", null);
xmlExceptionTreeList.copyElementTree(ExceptionTreeList);
byte [] msgAsBytes = localEnvironment.getRootElement().getLastChild().toBitstream(null,null,null,0,0,0);
String exAsText = new String(msgAsBytes); |
