Unfortunately it happens infrequently enough that I am unable to track it to that level, however it does happen enough that it is a problem. Is there is higher level of debug I can turn on in SOAP?
I know that generally, the data being transferred is very small, no string ever exceeds 20 characters. It would be difficult to revert back to 2.1, as there are already clients in the wild... I am hoping that 2.3 fixes the problem.

SOAP-2_2 (release version from website) Transport HTTP J2SE1.4.0 Specifically when trying to unmarshal a reply where the reply is a rather long string that is actually a [recursively] quoted XML message (i.e., it contains a *lot* of < stuff.) Somewhere in across the JAXP interface something creates a *very* large DOM tree (text-entity-text-entity etc...) and apparently this creates and releases large amounts of data structures. Even though the total size of the message is about 73K, the heap grows 9 to 10 Megabyte during the unmarshal operation. [ick!] Strictly speaking, it doesn't hang (at least in our case) since it does come back after 20 minutes or so. But that's not easy to tell an end user with a straight face (event though I practice every day.) The fix was to revert to the SOAP 2.1 (release version from website) using the Xerxes 1.4.3 parser. I suspect the size of the string is the critical factor. Small strings go very fast, but the time spent appears to be O(n^x) where x is > 3 relative to the size of the string. (I have not spent too much time mapping the exact curve.) There is a bug in the bugzilla database that appears related (2209) http://nagoya.apache.org/bugzilla/show_bug.cgi?id=2209 But it is actually quite old (almost a year and still NEW) and appears to have no recent activity (other than as a dumping-ground for duplicates). --j PS I have added the essence of this report to bug 2209. _______________________________________________________________ On Tuesday 14 May 2002 06:52 am, Jeremy Levy wrote: > Has anybody noticed that on occasion making a soap > call hangs? > > I have traced to back to this line: > > Response response = call.invoke(urls, ""); > > What happens it it never comes back from that line and essentialy > hangs the entire thread.. > > Has anyone expericened this or does anyone have any > ideas? > > Jeremy > > __________________________________________________ > Do You Yahoo!? > LAUNCH - Your Yahoo!
