Re: Error while fetching data from a web service using SOAP

Tue, 12 Nov 2002 12:54:14 -0800

Well the performance you are getting is examplary from my standards.
Let me expalin you and may be then u can give me a pointer. My webservice is returning a java.lang.String which is mapped as xsd:String in my wsdl. But actually this String is an XML file on which I have done a .toString() and returned as a String for ease of use to my client.

Do you think this can cause any problem since browser would actually put all the escape characters.

Can I actually return a XML file and like a org.w3c.Element object(Actually I am using JDOM so I have org.jdom.Element).

Also let me know which versin of Apache SOAP yu are using and I can update my .jar files.

thanx for following this up.

Bhanu Pabreja.

While the performance of Apache SOAP is not at all times exemplary, you
are experiencing unusually poor performance. I have a simple service
where the client sends the contents of a file as a byte array and the
server returns a slightly modified version of the byte array. On a 400
MHz AMD K6-III running Win2k, JDK 1.3.1, Tomcat 4.0.1 and the newest
build of Apache SOAP, the round trip time is 17 seconds for a 1.7 MB
file. Note that this includes encoding the byte array in Base64, which
means the data transmitted is 33% larger than the file itself.
