IBM Integration bus, parsing json

Hello I have a problem to parse any JSON in IIB Toolkit. The exception thrown by java compute node is: java.lang.NoClassDefFoundError: org.json.JSONObject

I am parsing incoming JSON messages in UTF-8. I already tried to get them in JSON, but accepting them as BLOB and converting to JSON UTF-8 works for me.

String messageText = new String(outMessage.getRootElement().getLastChild().getLastChild().getValueAsString());
messageText = new String(DatatypeConverter.parseHexBinary(messageText),"UTF-8");
JSONObject json = new JSONObject("{}");

I would love to create JSON object from JSON string in UTF-8

Many thanks in advance!

So what you are trying to do is a bit of a no-no. You're trying to use the Java class JSONObject rather than using the builtin IIB Java Parser.

Have a look at MbElement in particular the methods createElementAsLastChild(java.lang.String parserName) and createElementAsLastChildFromBitstream.

As per my earlier answer never forget your are trying to build a tree of elements.

One other trick I sometimes use is to build a sample output message and send it to an Input node connected to a Trace node. I then use the Trace node output to write code to build my actual output tree, you can even put a Trace node after your JavaCompute node to see what the Element tree you've currently built looks like and correct your mistakes. I mostly use this method for SOAP messages which can be quite complex.

If you really want to use external Java classes then search for Using JAXB with a JavaCompute node and follow the links from that article.
