Hi All
I am using Axis 1.6alpha ( CVS checkout ). I am trying to run a
modified array example (CPP:RPC) which segfaults if
numbers returned are > 209 but works for numbers > 100000. ( I think
this may be some sort of a memory error )
I have attached the modified client and server files of the Array
(CPP:RPC) example with the WSDL. (The rest is the files as generated by
wsdl2ws)
The server does return all the values which is seen in the SOAP-RESPONSE.
The example works fine for all values when run under gdb.
I have also tried passing various values to setServerTimeout() and got
the same results.
Any pointers to why this is happening and how it can be solved?
Cheers
Krishna

Sorry for the delay in responding.
However, the server may have run into problems due to some memory
errors (these effested client side as well) I fixed some memory
errors. Could please try now and see?
Thanks,
Samisa...

Hi Fred/All
Thanks for the reply. Do you have any idea as to why the first error is
occurring or/and what I may do to debug it.
Cheers

Hi Krishna,
Answering your second question, '2. Some text - "ffb" came
into the message'. This is fine. What is happening is when you have
a large message it cannot be sent as a single block, but has to be cut
up into smaller blocks or 'chunks'. What you are seeing is called
'chunking' and the numbers are actually hexadecimal numbers that begin
each chunk and tell the transport how big that chunk is.
Regards,
Fred Preston.

Subject: Array example fails for large number of numbers
Hi All
I was implementing the Array example on Axis 1.6 alpha. ( echoIntArray -
The client sends an array of numbers and the server echoes the array
back to the client ). This is a RPC based webservice
The example seemed to work fine for < 200 numbers. For numbers > 200 the
I had the following problems
I have attached the source code and stubs along with this email.
Please find parts of the SOAP_RESPONSE below.
1. The server did not echo back all the numbers
<item>1159</item>
<item>1160</item>
<item>1161</item>
<item>1162</item>
<item
The message stopped here it was supposed to return 10000 items.
2. Some text - "ffb" came into the message
<item>208</item>
<item>209</item>
<item
ffb
210</item>
<item>211</item>
<item>212</item>
<item>449</item>
<item>450</item>
ffb
<item>451</item>
<item>452</item>
Is this a known issue? The output above was captured using ethereal.
Cheers
Krishna
