cvs commit: xml-axis/java/src/org/apache/axis/client Service.java
dug 02/03/26 04:44:47
Modified: java/src/org/apache/axis/client Service.java
Log:
Add some basic caching of WSDL. WSDL will not change very often
so cache what we see - the improvement in speed in cases where
we reuse the same WSDL(but not the same Service object) is quite dramatic.
Some thing nice to add in the future would be some basic algorithm that
would limit the size of the cache and drop the least-used (or last used)
one.
