cvs commit: ws-axis/java/webapps/axis happyaxis.jsp
dominik 2004/12/20 17:56:34
Modified: java/webapps/axis happyaxis.jsp
Log:
As a follow up for AXIS-1674, I updated happyaxis page to detect which version of SAAJ API is available in the classpath. If SAAJ API is available but does not pass the test, happyaxis reports an error.
