Hi Juan,
Platform update is done through the window; did not modify project.properties
file manually.
There is one modification to generate Java classes from a wsdl file, using
"wsimport" which is present in JAVA_HOME/bin.
This, however, works well as long as JDK 8 is used. Build file is working with
Netbeans 8.0 and also when netbeans.conf is updated to use JDK 8 in NB 12.2
It is using JDK15 as:
1. In build output in debug mode, it shows "Detected Java version 15" and "Java
Version: 15.0.1"
2. wsimport is not present in JDK15
3. Even if I temporarily skip wsimport target, it later fails on not finding
classes/packages like com.sun.tools.internal.xjc.XJCFacade,
javax.xml.bind.annotation (just like you mentioned)
Here's the dump of properties used by ant (<echoproperties />), trimmed to
important values:

As you can see, many properties related to java are pointing to JDK 15.
Any workaround?
Thanks,
Karan
