Can we compile our code using your APIs using jdk 1.5?
I would be very surprised if a JDK1.4 built JAR failed to work in a Java5 environment.
Please note that current Tamino Servers only include a Java 1.4 runtime environment. This means that you would not be able to use Java5 specific JARs from within Tamino (e.g. in server extensions).
However I would expect Java5 built applications using the API to access Tamino to work.
I confirm I use JDK 5.0 with the Tamino API4J. I haven’t found no problem.
