MQSeries.net :: View topic - Java user-defined node cannot connect with node properties

Dmitry · Posted: Fri Jun 22, 2018 8:46 am Post subject:

Hello.

I have spent last 2 week for create user-defined node by Java.
The are huge heap of problems.
But the last one problem I cannot resolved.
My node java class cannot access to node properties.
MQ 9.0
IIB 10.0.0.12

Sometimes properties in classes init like null but sometimes like ""(zero length string).

When I redeploy app with UD node setLevel() method has not done.
But when I readd jar with node class and restart integratiation node setLevel() have done.

I expect then every app deploy with UD node set's methods will be done.

For me it looks like a magic.

Can somebody experience with java UDN with properties?

[package ...

public class Log4jNode extends MbNode implements MbNodeInterface {

private String logLevel;
private String pattern;

private String date;

@Override
public void evaluate(MbMessageAssembly arg0, MbInputTerminal arg1)
throws MbException {
MbMessage outMbMessage = new MbMessage(arg0.getMessage());
MbMessageAssembly outAssembly = new MbMessageAssembly(arg0, outMbMessage);
outMbMessage.getRootElement().getLastChild().getLastChild().createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "level 10.22 " + date, logLevel); outMbMessage.getRootElement().getLastChild().getLastChild().createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "pattern", pattern);
getOutputTerminal("out").propagate(outAssembly);
}

public String getLevel() {

return logLevel;
}

public void setLevel(String level) {
date = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(new Date());
if (date == null)
date = "nullS";
this.logLevel = level;
