java.lang.RuntimeException: file name is is too long ( > 100 bytes) 异常

严重: Servlet.service() for servlet action threw exception
java.lang.RuntimeException: file name '....' is too long ( > 100 bytes)

at org.apache.commons.compress.archivers.tar.TarArchiveOutputStream.putArchiveEntry(TarArchiveOutputStream.java:187)

解决方式，查看commons-compress-1.3/apidocs/index.html,搜索

TarArchiveOutputStream

即可看到

Field Summary
protected org.apache.commons.compress.archivers.tar.TarBuffer	buffer
staticint	LONGFILE_ERROR Fail if a long file name is required in the archive.
staticint	LONGFILE_GNU GNU tar extensions are used to store long file names in the archive.
staticint	LONGFILE_TRUNCATE Long paths will be truncated in the archive.

中间红色加粗的部分就是解决此问题的方式。

Some versions of tar do not support names (paths, really) longer than 100 chars. If you've got paths longer than that, you won't be able to use a version that doesn't allow lengths > 100 chars. Fortunately there seem to be other choices. I don't see a way to use com.ice.tar for this. But it looks like org.apache.tools.tar will work. Try this: tos.setLongFileMode(TarOutputStream.LONGFILE_GNU); Note also that you may want to put in some logic to modify the names a bit when you create entries. If you're tarring up everything from c:\csharpzip (as the base directory) you probably don't want to include the c:\csharpzip in the name. Because when someone untars the files, they will probably be on another machine with a different root directory. Insead you want a relative path name. Which means replacing c:\csharpzip\SharpZipLibSample\samples\DIME\DimeDataSetServiceConsumer\DimeDataSetServiceConsumer.csproj with SharpZipLibSample\samples\DIME\DimeDataSetServiceConsumer\DimeDataSetServiceConsumer.csproj [now i use listFiles what you suggested(and recommended), is this implementation true, i mean the code. It looks correct, yes. I haven't tested it carefully though - you'll have to do that.
