Why can't i perform this example successfuly??

To each expert:
I load an XML file into tamino, which is a exmaple
bib.xml provided from tamino server. It’s content is as follows:



TCP/IP Illustrated
StevensW.
Addison-Wesley
65.95


Advanced Programming in the Unix environment
StevensW.
Addison-Wesley

Data on the Web

and I run an XQuery like “update delete input()/bib//affiliation” in the either Interactive Interface or Software AG Tamino XQuer appliction.

I get the message “<ino:message ino:returnvalue=“8552”>
<ino:messagetext ino:code=“INOXME8552”>Not a valid request</ino:messagetext>
ino:messagelineIt is not possible to open a cursor with XQuery Update Request.</ino:messageline>
</ino:message>” from Interactive Interface.
If I perform on the Software AG Tamino XQuer appliction, I won’t get any error messages.

I try to perform in my writing JSP program. It will get the error message "XQuery parsing erro…"

If any expert could tell me how to solve this problem?

Thank you very much.
