Logging from an Event Handler

bhanley

I am having trouble with a Java-based event handler bound to an event on a BIRT report. It is generating a Null Pointer Exception when I run it on the iServer. Where would an event handler write its logs to? I have calls to System.out.println in the code, but I cannot find the correct logs. A better solution would be to have the event handler use log4j, but i do not know where to put my log4jproperties file on the iServer.

Thanks for any help!

Answering my own question, this solution below is working great.<br />

<br />
The iServer Java factory and view server (where the BIRT runs) use JUL (java.util.logging). The output goes to: <br />
<br />
Factory: jfctsrvrXXXXX.log<br />
<br />
View server: jsrvrXXXX.log<br />
<br />
The java.util.logging (JUL) instance can be retrieved by calling the following in your code in your class.<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>ILogger logger = Logger.getLogger(<Your class name>.class.getName());</pre>
<br />
Replace the <Your class name> with the current class name.<br />
<br />
Since we registered a log handler(log file) at root level, any logger registered under it will be handled by it.<br />
<br />
