Hi all, sorry for the long post but we're facing this problem and any help would be greatly appreciated. We have a method with this signature:
byte[] getDocumentDataByteArray(String param1, String param2) This method, based on param1 and param2, retrieves a document from the server and returns it to the client with a byte array. Using JBuilder we'have generated both client and server code with the Axis Toolkit integrated in this IDE. After making some test with little files (40/50Kb), we'have tried with bigger files (1/2 Mb). With these files we experienced a serious performance problem so we decided to see what was happening "behind the scene" with Ethereal. The sniffing is attached: ------------------ Start request ---------------------- POST /my-services/services/myServices HTTP/1.0 Content-Type: text/xml; charset=utf-8 Accept: application/soap+xml, application/dime, multipart/related, text/* User-Agent: Axis/1.1 Host: localhost.localdomain Cache-Control: no-cache Pragma: no-cache SOAPAction: "" Content-Length: 706 <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <soapenv:Body> <ns1:getDocumentDataByteArray soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:ns1="http://filenet";> <param1 xsi:type="xsd:string">uWlkqDM045IfYRgD8rouTX4FBw9TILtfzC52Kk27ehQVd4AeqpijKucpJDXlPmnz+RdJjKH2ViJPhMR/XyiAWC+t83jV0vgA25Hwh6oA/YitfBBFTDm0tkmXDD8VOTkmBu2iwHW45IcZXqEhQvnHTPUN77HXkDljuu6vsYAiMUM=</param1> <param2 xsi:type="xsd:string">003670716</param2> </ns1:getDocumentDataByteArray> </soapenv:Body> </soapenv:Envelope> ------------------ End request ---------------------- ------------------ Start response ---------------------- HTTP/1.1 200 OK X-Powered-By: Servlet 2.4; Tomcat-5.0.28/JBoss-3.2.6 (build: CVSTag=JBoss_3_2_6 date=200410140106) Content-Type: text/xml;charset=utf-8 Date: Mon, 13 Dec 2004 14:07:28 GMT Server: Apache-Coyote/1.1 Connection: close <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <soapenv:Body> <ns1:getDocumentDataByteArrayResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:ns1="http://myservices";> <ns1:getDocumentDataByteArrayReturn xsi:type="soapenc:Array" soapenc:arrayType="xsd:byte[1671291]" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/";> <item>80</item> <item>75</item> <item>3</item> <item>4</item> <item>20</item> <item>0</item> <item>0</item> <item>0</item> <item>12</item> <item>0</item> <item>54</item> <item>117</item> <item>-92</item> <item>48</item> <item>-17</item> <item>100</item> <item>-57</item> <item>34</item> <item>-23</item> <item>127</item> <item>25</item> <item>0</item> <item>0</item> <item>-40</item> .....and so on until the end ------------------ End Response ---------------------- As you can see we think that the big problem is related to the fact that the byte array of this file of 1,6 Mb is returned using 1,6M element <item> containing the value of a single byte (16 byte to send 1 byte of payload...). Why do this happens? We have another method which create a document with this signature <return_type> createDocument(String param1, byte[] documentData) and this document passes the content of the file as an encoded string and not with all this <item> elements. Why the getDocument method does not use the same way to send a byte array? We know that to send large file DIME would be best but we would like to understand why this happens before investigating DIME......
