In
my last blog "How-to create a web service with attachments (SOAP With Attachments)",
we generated a web service that
takes binary data and use it with
SOAP with attachments and said
that we can use the standart way
to pass the binary data also.
In
this blog we will generate the
standard web service without attachments,
create a standalone proxy to test
both services(SOAP with attachments
and without attachments) and see
the difference. By the way if
we ask what's the difference?
The answer is the performance..
For
the second web service, we simply
generated the web service from
the same ejb method but this time
we use HTTP SOAP while configuring
the service. After creating the
two services, in order to see
the difference in SOAP messages,
call the web services with dummy
data from the web services navigator..
*First
SOAP with attachments, mime
request (1st web service):*
POST /SOAPWAttachWS/ConfigWAttachment?style=mime HTTP/1.1 Host: local.bb.name.tr:50000

SOAPWOAttachmentWSImpl service = new SOAPWOAttachmentWSImpl();
ConfigWOAttachmentBindingStub ws = (ConfigWOAttachmentBindingStub)
service.getLogicalPort(ConfigWOAttachmentBindingStub.class);
byte[] fileContent = readFile(readPath);
String productName = "WOATTACH_"+new SimpleDateFormat("ddMMyyyy_HHmmss").format(new java.util.Date());
String result = ws.registerProduct(productName,fileContent);
long e = System.currentTimeMillis();
System.out.print("-testWithoutAttachment :");
System.out.println((e-s)); }
catch (Exception e) {

e.printStackTrace();

private static void testWithAttachment(){
try{
long s = System.currentTimeMillis();
String readPath = "C:

SOAPWAttachWSImpl service = new sOAPWAttachWSImpl();
ConfigWAttachmentBindingStub ws = (ConfigWAttachmentBindingStub) service.getLogicalPort(ConfigWAttachmentBindingStub.class);
byte[] fileContent = readFile(readPath);
String productName = "WITH_ATTACH_"+new SimpleDateFormat("ddMMyyyy_HHmmss").format(new java.util.Date());

}
private static byte[] readFile(String readPath) throws Exception {
FileInputStream infile = new FileInputStream (readPath);
int infilelength = infile.available();
byte[] key = new byte[infilelength];
infile.read (key);
infile.close();
return key;
}
What
I did in this test is send a
binary data to my web services
n times, and measure the time
that passes between each request.
And
here are the test results for
10x Test:
-
testWithoutAttachment :16603
-
testWithoutAttachment :16540
-
testWithoutAttachment :20297
-
testWithoutAttachment :16430

In
order to get more accurate results
we should increase the number
of calls, however 10x is enough
for seeing the performance penalty
which is around 40%.
