BIRT Viewer

stuart

Hi All,

Since the release of BIRT 2.3.2 have there been any changes/improvements to the BIRT viewer - especially in the area of error handling and the ability to provide a custom error page?

Thanks,

Stuart.

Hi stuart,

What kinds of errors are you trying to catch?

Hi Michael, 
 
See "stack trace" image. I was wondering if it was possible to provide a more user friendly error page rather than the stack trace.

Hi! I'm also wondering how can I catch the BIRT Viewer exceptions. I want to write a log in DB when viewer exception occurs.

EDIT: 
I found the solution that works for me. 
Make a servlet which extends org.eclipse.birt.report.servlet.ViewerServlet. 
Change the mapping in the web.xml file to point the new servlet instead of the ViewerServlet. 
Override just the __handleNonSoapException method. There you can handle the exceptions and provide user friendly errors. 
Here I make request to another servlet which logs the error in DB.

Hi spooky, 
 
Thanks for the info. If you had time, you could post a detailed explanation of what you did to handle the exceptions in the devShare for others to see. You'd also be entered in the <a class='bbc_url' href='http://www.birt-exchange.org/org/wiki/index.php?title=DevShare_Contributor_of_the_Month_Contest'>devShare Contributor of the Month</a> contest.

Hi Spooky, 
 
I tried overriding the __handleNonSoapException method but it doesn't seem to work for me. I put he extended org.eclipse.birt.report.servlet.ViewerServlet class in the classes directory of the webviewer but it seems to ignore it. Any ideas? 
 
Thanks, 
 
Stuart.

Hi, 
 
This is how my overriden method looks like: 
<pre class='_prettyXprint _lang-auto _linenums:0'>@Override
protected void __handleNonSoapException(HttpServletRequest request,
HttpServletResponse response, Exception exception) throws ServletException, IOException {
exception.printStackTrace();
BirtUtility.appendErrorMessage(response.getOutputStream(), exception);

// YOUR CODE GOES HERE
}
</pre>
The most important thing is to define your servlet in the web.xml this way: 
<pre class='_prettyXprint _lang-auto _linenums:0'><servlet>
<servlet-name>ViewerServletProxy</servlet-name>
<servlet-class>com.test.ViewerServletProxy</servlet-class>
</servlet></pre>
and to modify the used mapping (for me this is "frameset") to point your servlet: 
<pre class='_prettyXprint _lang-auto _linenums:0'><servlet-mapping>
<servlet-name>ViewerServletProxy</servlet-name>
<url-pattern>/frameset</url-pattern>
</servlet-mapping></pre>
 
This is everything
