Problem Downgrade form jdk1.5 to jdk 1.4

[alfviles]

Hi guys,
I have a problem with dowgrade from jdk1.5 to jdk1.4 with Spring Web Flow 1.0.5 version, I have read that SWF 1.0.5 is compatible with jdk1.4, and I tried to dowgrade it but the compiler give me the next errors using jdk1.4:

package: org.springframework.webflow.action
class: ResultObjectBasedEventFactory
error: java.lang.Enum cannot be resolved to a type

private boolean isJdk5Enum(Class type) {
if (JdkVersion.getMajorJavaVersion() >= JdkVersion.JAVA_15) {
return type.isEnum();
} else {
return false;
}
}


private static class EnumNameResolver {
public static String getEnumName(Object enumValue) {
return ((java.lang.Enum) enumValue).name();
}
}

package: org.springframework.webflow.conversation.impl
class: JdkConcurrentConversationLock

Impossible to import:
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;


I need to do this downgrade version of jdk, thanks a lot for your help in advance
Kind regards!

Web Flow works fine with JDK 1.4 but it looks like you're trying to compile the sources. According to the Web Flow readme though, you need java 1.5 to build it.

Thanks for your answer, I'll build it with java 1.5,
