java error handler

ShlomiW

Hi all, 
 
I'm looking for an example for a JAVA error handler for birt. 
I have founded many examples but I can't reused them in my reports. 
 
When I tried to write the following code in the "beforeFactory" section. 
<pre class='_prettyXprint _lang-auto _linenums:0'>
try {
reportContext.setPersistentGlobalVariable("newParametersName", parametersName1);
}
catch (IOException e) {
e.printStackTrace();
}
}
</pre>
 
I get this error message: 
<pre class='_prettyXprint _lang-auto _linenums:0'>invalid catch block condition</pre>
 
I have looked but I can't find any reference for why I get this error message. 
 
Please help my to understand and write good code :-) 
Have a great day 
Shlomi

I haven't tried it but I think it needs EngineException 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>try {
// Some code
}
catch(EngineException e) {
// Error code
}</pre>

Try this. I just get the same error today.

try {
// Some code
}
catch(err) {
// Error code
}

But then what code can I used in order to display my error? 
Can I print it to a file? if so can you tell me what in the name of the function that I need to use? 
If I can't print the error to file can I display it on the screen? like with an <pre class='_prettyXprint _lang-auto _linenums:0'>echo(error text); [in php]</pre>
or <pre class='_prettyXprint _lang-auto _linenums:0'>alert(error text); [in JavaScript]</pre>
 
 
I hope that this comment is clear if not please write me back and I would try to explain again. 
 
Have a great day
