Does the sdk jar file exist in Workload automation DE?
If so, where can I get it?
Thanks in advanced
There is no sdk jar file for DE.
There is no single sdk jar file for any language.
The Java2 SDK (software development kit) is a JRE (Java Run Time Environment, aka the Java VM), plus tools such as compiler, select source code files and header files. You can freely download it here. It does contain multiple jar files as part of the software distribution.
