Error in Java compilation: \s7u.log (The system cannot find the file specified)

Question

Hi there,
I got an error when I tried to compile a group of sqlj and java files. The error below:

Any suggestion appreciated.

Answer 1

Having not seen this before, I assume that the issue is that the command line string is too long when Javac is invoked.
Here are a few things to reduce the size of the command line:
- do not use the CLASSPATH option, but set the CLASSPATH environment variable (you can to that in a .bat file)
- do not provide the .java files but rely on the implicit make capability in both, the SQLJ translator and the Java compiler. (Note: you must mention all of the .sqlj files that your program requires, do not rely on implicit make to find all of those.)
- you can perform the -ser2class conversion as a separate step (see the SQLJ FAQ), as well as the Java compilation
- there may or may not be a facility in your operating system to increase the size of the environment (and this may or may not have an effect on the maximum command line length)
- you could try to omit the -passes option and see if that helps (that may actually be where your invocation if failing in the first place, in that it cannot write to some temporary file).
Let us know how it goes. Thanks!
