Hi everyone,
I have an issue with a java service.
I had to add two external jars to my package/code/jars and in the service development project /lib directory, which allowed me to import the classes in the code without any exception to be raised, but I still can’t compile the service due to the following error:
ISS.0014.9116] Unable to locate or start compiler
I already added my jars to the build path of the project, and the watt.server.compile setting refers to the compiler (also tried to put it to the default value)
I’m getting out of ideas to resolve my issue here, I’m pretty sure I tried everything that was listed on here, but no luck with this.
If someone has an idea, I’ll be glad to hear about it 
Thanks!
It might be caused by the java classpath being too long due to Windows OS limitation. You can try setting watt.server.compile and watt.server.compile.unicode to empty.
watt.server.compile=
watt.server.compile.unicode=
If these properties are omitted or empty, the server uses the JVM internal Java compiler to compile Java services.
HTH,
Theo

Well appreciated @Theodore_Ezell1
This works well with 10.11 version!

I was running into the same issue in 11.1 Service Designer. This tip worked. Thanks

That error usually happens when Integration Server can’t find the Java compiler. Make sure the watt.server.compile setting and your JAVA_HOME both point to a full JDK, not just a JRE—javac is only included with the JDK. If you’re using Java 9+, ensure the JDK is properly set since tools.jar is no longer separate.
