[jira] [Commented] (COMPRESS-137) TarArchiveEntry.getFile() always
returns null + no way to get an InputStream from TarArchiveInputStream
similar to what you do with
(java.util.zip.ZipFile())..getInputStream(ZipEntry);
Posted by "Albretch Mueller (JIRA)" <ji...@apache.org>.

Albretch Mueller commented on COMPRESS-137:
-------------------------------------------
OK, let me put it this way. There is:
~
java/util/zip/ZipFile.html#getInputStream(java.util.zip.ZipEntry)
~
Where is (something (even a hack!) like):
~
final BZip2CompressorInputStream BZ2KIS = new BZip2CompressorInputStream(new FileInputStream(IFlBZ2));
final TarArchiveInputStream TArkIS = new TarArchiveInputStream(BZ2KIS);
TarArchiveEntry entry = (TarArchiveEntry)is.getNextEntry();
InputStream EntryIS = TArkIS.getInputStream(entry);
~
so that you may go then, may go:
~
XMLReader XMLRdr = SAXPrsr.getXMLReader();
BufferedReader BfrRdr = new BufferedReader(new InputStreamReader(EntryIS, "UTF-8"));
XMLRdr.parse(new InputSource(BfrRdr));
~
I am not sure if your answer to my question/request was that "getFile shouldn't be there to begin with"
~
Why do you have to untar the whole thing in order to get what you want?
~
Why can't you get a grip just on the InputStream relating to one entry inside or a tarball? That was/is my question.
~
Thanks

[jira] [Commented] (COMPRESS-137) TarArchiveEntry.getFile() always

deyaa commented on COMPRESS-137:
--------------------------------
I think what Torsten meant is that you should use the original TarArchiveInputStream to read the data of the next file, as shown here:
{code}
is = new FileInputStream(tarfilename);
debInputStream = (TarArchiveInputStream) new ArchiveStreamFactory().createArchiveInputStream("tar", is);
TarArchiveEntry entry;
while ((entry = (TarArchiveEntry) debInputStream.getNextEntry()) != null) {
final File entryFile = (entry).getFile();
final String entryName = entry.getName();
if (!entry.isDirectory()) {
System.out.println("consuming file: " + entryName);
Document doc = new SAXBuilder().build(debInputStream);
} else {
System.out.println("consuming folder: " + entryName);
}
}
{code}
The problem with this is that the ??depInputStream?? is closed by the ??SAXBuilder??, so the second call to ??debInputStream.getNextEntry()?? will throw ??java.io.IOException: input buffer is closed??

-------------------------------------------
Let me add that my goal (as explained in user@commons.apache.org: [compress] trying to feed data from tar.gz and tar.bz2 files directly to an XMLReader ...) is being able to do something like this:
~
BufferedReader BfrRdr = null;
XMLReader XMLRdr = null;
FileInputStream FIS = null;
ZipInputStream ZIS = null;
ZipFile ZFl = null;
int OPEN_READ = 0x1;
ZipEntry ZEntry;
// __
try{
SAXParserFactory SAXFctry = SAXParserFactory.newInstance();
SAXFctry.setValidating(false); // stop standard validation to allow custom schema
SAXFctry.setNamespaceAware(true);
SchemaFactory SchmFctry = SchemaFactory.newInstance(javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI);
SAXFctry.setSchema(SchmFctry.newSchema(new Source[] {new StreamSource(aIXSDFl)}));
SAXParser SAXPrsr = SAXFctry.newSAXParser();
// __ Create and register the content handler
XMLRdr = SAXPrsr.getXMLReader();
XMLRdr.setContentHandler(new DefaultHandler2());
// __
File IZFl = new File(aIXMLFl);
ZFl = new ZipFile(IZFl, OPEN_READ);
// __
Enumeration<? extends ZipEntry> ZENum = ZFl.entries();
while(ZENum.hasMoreElements()){
ZEntry = (ZipEntry)ZENum.nextElement();
System.out.println("// __ XML Scanning: |" + ZEntry.getName() + "|");
InputStream IS = ZFl.getInputStream(ZEntry);
BfrRdr = new BufferedReader(new InputStreamReader(IS, "UTF-8"));
// __
XMLRdr.parse(new InputSource(BfrRdr)); // XMLReader is directly fed the InputStream from the zip file
// __
IS.close();
}
// __

[jira] [Commented] (COMPRESS-137) TarArchiveEntry.getFile() always

Torsten Curdt commented on COMPRESS-137:
----------------------------------------
As demonstrated in
https://svn.apache.org/repos/asf/commons/proper/compress/trunk/src/test/java/org/apache/commons/compress/ChainingTestCase.java
chaining works just fine.
You misunderstood the meaning of "getFile" (TBH I think that method should not exist at all) and are using the API the wrong way. Compress uses the same approach as the standard JDK classes.
In your case this means you need to find your ArchiveEntry and then the InputStream is positioned right where you need it. Search for "testTarUnarchive" to see an example.
