JDK-4191800 - FileURLConnection doesn't implement getOutputStream()
Description
The following testcase fails in sameJVM/otherJVM on Solaris.

The 'file' protocol doesn't support output so the following two testcases

javax/activation/URLDataSource/getInputStream_Test.java
javax/activation/URLDataSource/getOutputStream_Test.java

fail at line 81 in the testcase sources.

RUNTIME OUTPUT:
--------------
java.net.UnknownServiceException: protocol doesn't support output
        at java.net.URLConnection.getOutputStream(URLConnection.java)
        at javax.activation.URLDataSource.getOutputStream(URLDataSource.java:115)

        at javasoft.sqe.harness.lib.ExecJCKTestSameJVMCmd.executeStandardTest(ExecJCKTestSameJVMCmd.java:116)


The same thing occurs for getOutputStream_Test.java

EVALUATION This is really an RFE for java.net. The Java(tm) Platform does not support writing to file URLs. ---- This will not be supported in 1.2, which is feature frozen at this time. benjamin.renaud@Eng 1998-05-06

WORK AROUND Make a new File object, using the idiom: new File(url.getFile()) and write to it. benjamin.renaud@Eng 1998-05-06
