Error in version of JDK and compatibility of JDK issues
I have installed jdk1.4 in my m/c..
I have downloaded an application and installed in Eclipse.
In the process of installing it statd like: Check the Properties -> Java Compiler to make sure that the compliance level is 5.0; it's possible that this may not happen automatically with the Import operation.
it seems like we have to install jdk5.0. Am i correct?
I havnt installed 5.0 .. so i got error like
java.lang.UnsupportedClassVersionError: test/Params (Unsupported major.minor version 49.0) - one file
java.lang.UnsupportedClassVersionError: forms/SelectionReentry (Unsupported major.minor version 49.0) - for another file
and the project marked with error like red x
Please suggest me wht changes required. if the change is to install jdk5.0 then
the question is :
Can i install 2 jdk in my machine? like i have already 1.4 and then can i install again 5.0 with the availability of 1.4 (since i cant taken off 1.4 - situation is like that (so i cant simply upgrade to 5.0))
if i can install 2 jdk then, the question is:
i have configured 1.4 in classpath in environmental variables.. so is it possible to add again an another jdk in this classpath. (Also note- in eclipse i guess no need of classpath configuration for jdk5.0. it already there in the list of Properties -> Java Compiler..so Is that like no need of classpath setting of jdk5.0 in Eclipse)
Please let know.. Thanks in Advance
