ALDSP 3.2 - How to create JMS message from ALDSP

Question

Is there a way to write a jms message from ALDSP?
I want to be able to perform database updates to a database and also write a message to queue in a transaction.
Thanks

As per my understanding only one resource can be non-transactional. In this case it would be the Web Service.If you have n data sources and the first n-1 are transactional and the nth one is not - if you update the first n-1 successfully, and the nth one fails - then you just throw an exception and the updates to the n-1 data sources get rolled back. If an update to one of the n-1 data sources fails you throw an exception and the update to the nth data source never happens. In your case, it's up to you to ensure the updates are executed in the correct order (how you write your XQSE procedure).
Will the call to write a jms message from a Java function in ALDSP participate in the database transaction? DSP doesn't suspend the current transaction when calling a Java function. So yes, the JMS call would participate in the same transaction as the database call.
If you want to dump out the transactionId in your java function in the same format as it appears in the DSP Audit, you can use :
public String byteArrayToHexString(byte in[]) {
StringBuffer out = new StringBuffer(in.length * 2 + 2);
out.append("0x");
for(int i = 0; i < in.length; i++) {
byte ch = 0x00;
ch = (byte) (in[i] & 0xF0);
ch = (byte) (ch >>> 4);
ch = (byte) (ch & 0x0F);
out.append(HEX[(int) ch]);
ch = (byte) (in[i] & 0x0F);
out.append(HEX[(int) ch]);
return out.toString();
}
