Copy file exception with TrueZIP

Question

Here is my code to copy a war file to another using TrueZIP.

TFile srcFile = new TFile(sourceFilePath);
TFile destFile = new TFile(destFilePath);
if (!destFile.getParentFile().exists()) {
    destFile.getParentFile().mkdirs();
}

try {
    srcFile.cp_rp(destFile);
    TVFS.umount();
} catch (IOException e) {
    e.printStackTrace();
}

For example, source file location:

I:\Code-Base\test.7.2.0\projects\test\main\branches\test.7.2.0_for_test\ui\portlets\dist\portlets.war\WEB-INF\server-config.wsdd

and destination location:

D:\deploy\work\237798_237980\web\deploy\prtlets.war\WEB-INF\server-config.wsdd

I've already checked that both paths exists, but I get an InputException error::

Answer 1

TrueZIP does a simple test to check if the archive file is writable. If this test fails, the archive file system is set read-only as indicated by the exception.

In most cases, this is simply an issue with the access permissions. But Windows is particularly bitchy. For example, if there is another tool concurrently accessing the archive file (many Explorer plug-ins do this) then the file is effectively read-only, too.

So please stay away from the archive file (and best, its directory) while the operation is running.

Answer 2

You cannot do a replace on a read-only file, because you would have to delete it, i.e. write to it.

Make sure your destFile is writeable.
