[EJB 3.0] - Re: Exception recieving problem
by voidhawc
We are using jboss-4.0.4.GA-Patch1-installer.jar using the ejb3 profile (not clustered) during installation.
We are using JDK 1.5.0_06-b05 to compile the source with a ANT build script run using ANT 1.6.5.
Just having a look at your code snippets, does the annontation order matter?
Here's the build script for one of the layers.

The place where it is called in the Backing Bean to test things
| try {
| SpratSearch s = new SpratSearch(new Integer(-1));
| SpratSpecies t = Qm.searchForSpecies(s);
| result.setDesc("Found " + t.getMigratoryScientificName());
|
| } catch (PimInvalidSearchTermException e) {
|
| result.setDesc(e.getMessage());
| result.setPass(true);
|
| } catch (Exception e) {
| if (e instanceof PimInvalidSearchTermException) {
| PimInvalidSearchTermException t = (PimInvalidSearchTermException) e;
| result.setDesc(t.traceBack());
| result.setPass(true);
| } else {
| result.setDesc(e.toString());
| result.setPass(false);
| e.printStackTrace();
| }
| }
|
If it can identify the correct Exception the test passes otherwise it fails.
Hope this helps clarify what is happening.
Thanks for you time.
