Problem with servlet

Hi All, (Many thanks for providing the XWIKI RC2 release) I have created a servlet which return an XML document. The servlet was placed in the WEB_INF/classes. So it work correctly but returns in some situation strange content. According to my tests, the servlet code is correct but the wrong content is maybe related to the cache. /First situation, the servlet:/ ---------------------------- - It open a connection to database (XWIKI databased) - The servlet receive a parameter which is the name of an existing XWiki document - It send a SQL request for retrieving the content of the specified document: select XWIKI_CONTENT FROM ...WHERE XWIKI_NAME = XXXX), XXXX = is the full name of a document. - According to the content of my XWiki database the SQL request return only one document. - Then it process the document and return an XML document *RESULT: * - I got a correct result = * <?xml version="1.0" encoding="UTF-8"?> + 'A'* (whether I refresh the content in the internet explorer the result is the same) (the XML header + the content) /Another situation: / ------------------ - It open a connection to database - The servlet receive a parameter which *is similar to *the name *of a set of *existing XWiki document - It send a SQL request for retrieving the content of these documents: select XWIKI_CONTENT FROM ...WHERE XWIKI_NAME *like "%YYYY%"*), YYYY is 'string' for retrieving a set of documents *- The result is one document which is correct result according to the content of my database* - It retrieve the content in an /*while** loop*/ - process the the content - return the XML document Here the is JAVA code: ResultSet st = .....; String content = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"; while (st.next()){ content = content + processContent(st.getString(XWD_CONTENT)); } ... this.writeResponse(resp, content); // *content is an XML document* *** RESULT: - First content (in the explorer) = <?xml version="1.0" encoding="UTF-8"?> *A* (correct) - When I refresh the explorer = <?xml version="1.0" encoding="UTF-8"?> *A A * - I refresh again the explorer = <?xml version="1.0" encoding="UTF-8"?> *A A* *A* ... - N refresh = <?xml version="1.0" encoding="UTF-8"?> *A A* *A ...A (N times)* (where *A* is the same content as *the first situation*) The servlet was transformed to class with main method and it return correct result...!!! I have also made test under the last version 'XWIKI RC2' but got the same problem. Is it related to the cache memory? I spend two days trying to solve it but without success.... Any help will be deeply appreciated. Thanks in advance. Cheers ---------- Youcef Bey
