Try the following, it must throw an exception for every action.
We did like this
boolean result = false;
try {
action to perform
set result to true (if action perform success)
} catch (PropertyVetoException e) {
logger.error("iSeries call failed: " + e.getMessage());
throw new ExceptionFortisiMarket("iSeries call failed", null, e);
} catch (AS400SecurityException e) {
logger.error("iSeries call failed: " + e.getMessage());
throw new ExceptionFortisiMarket("iSeries call failed", null, e);
} catch (ErrorCompletingRequestException e) {
logger.error("iSeries call failed: " + e.getMessage());
throw new ExceptionFortisiMarket("iSeries call failed", null, e);
} catch (IOException e) {
logger.error("iSeries call failed: " + e.getMessage());
throw new ExceptionFortisiMarket("iSeries call failed", null, e);
} catch (InterruptedException e) {
logger.error("iSeries call failed: " + e.getMessage());
throw new ExceptionFortisiMarket("iSeries call failed", null, e);
} catch (ObjectDoesNotExistException e) {
logger.error("iSeries call failed: " + e.getMessage());
throw new ExceptionFortisiMarket("iSeries call failed", null, e);
} catch (ParseException e) {
logger.error("iSeries call failed: " + e.getMessage());
throw new ExceptionFortisiMarket("iSeries call failed", null, e);
}
logger.info("call to iseries " + result);
return result;
}

Subject: Showing root cause of error for Java tool box class which doesn't throw an exception
Hi all..
Does anyone have ideas how Java can report an error for a Java toolbox class when it doesn't throw an exception? Is there any way to programmatically dig out the cause when a method returns a value indicating the underlying i5 operation failed, but doesn't throw an error?
This code run on a windows server, it sets up the File objects to copy a jpg image from the Windows server to an i5.
// ensure that parent dir of dest file exists!
IFSFile parent = new IFSFile(sys, parentPath);
if (!parent.exists()) {
parent.mkdirs();
}
try {
in = new FileInputStream(sourceFile);
} catch( IOException e ) {
throw new Exception ( "Problem with input file, \""+sourceFile.getAbsolutePath()+"\" " + e.getMessage() );
}
try {
out = new IFSFileOutputStream(destFile);
} catch( IOException e ) {
throw new Exception ( "Problem with output file, \""+destFile.getAbsolutePath()+"\" " + e.getMessage() );
}
Today the IFSFileOutputStream(destFile) started to throw errors.
The problem is caused by IFSFile.mkdirs() failing. It fails silently, returning false.
I could change the code to:
if (!parent.exists()) {
if( !parent.mkdirs() ) {
throw new Exception("Unable to create parent folder, \""+parent.getAbsolutePath()+"\" ) ;
}
}
That would notify the caller of the method that a failure took place, but not the cause of the failure. parentPath is validated before the execution gets this far so IFSFile.mkdirs() shouldn't fail in the first place.
The failure is being caused by CPE3474, our IT department is working on that.
I'd like to do something like this to report why IFSFile.mkdirs()
failed:
if (!parent.exists()) {
if( !parent.mkdirs() ) {
// do something to dig out cause of error
throw new Exception("Unable to create parent folder, \""+parent.getAbsolutePath()+"\ caused by " + cause_of_error);
}
}
Any ideas what to replace the // do something... comment with?
Thanks
