The Situation:
I am attempting to create an application that recieves information from cfhttp
request containing a zip file as a java ByteArrayOutputStream object. This zip
file is then written to the hard disk and unzipped. The problem is that the zip
files are unreadable by the java.util.ZipFile library. Am I not writing the
files correctly? I have tested these files with winZip and everything works
fine there. Also I have used zip files created by winZip and application is
able to unzip the files without any problem.
The exact error I recieve when using one of these files is:
Object Instantiation Exception.
An exception occurred when instantiating a java object. The cause of this
exception was that: .
The error occurred in D:\ACM\CFC\mailbox.cfc: line 174
Called from D:\ACM\CONNTEST\index.cfm: line 8

opening the zip file
<code>

//get file entries

while(entries.hasMoreElements()){

//does file name contain a path

if (lenPath)

else
path = arguments.outDir;
//create path if it does not exsist
if(NOT directoryExists(path)){
fil = createObject("java", "java.io.File");
fil.init(path);
fil.mkdirs();
}
//open file
outStream = createObject('java', 'java.io.FileOutputStream');
outStream.init(arguments.outDir & name);
bufOutStream = createObject( "java",
"java.io.BufferedOutputStream");
bufOutStream.init(outStream);
//copy the input stream
inStream = zipFile.getInputStream(entry);
data = inStream.read(buffer);
while(data GTE 0) {
bufOutStream.write(buffer, 0, data);
data = inStream.read(buffer);
}
OutStream.close();
InStream.close();
}
}//end while loop
zipFile.close();
</cfscript>
