jdbc1 for 7.1.2 still not worked for me :((

 I tried with jdk118_v3 (glibc 2.1.3) from the same blackdown. The
result was the same :

/tmp/postgresql-7.1.2/src/interfaces/jdbc/example/blobtest.java:189:
Class example.Blob not found in type declaration.
    [javac]             Blob b = rs.getBlob("a");
    [javac]             ^


Then I renamed blobtest.java in blobtest.java2, switched back to
jdk117_v3 and I've got more errors:

I'd like both  jdk117_v3 and postgresql 7.1.2 work together.
Any ideas?

    Thanks,
