You can compile the above code into a java class. Then place the .class file
(or jar) into the CF classpath and reboot. Then you can use the ZipFileVerifier
class in place of java.util.zip.ZipFile in the unZipFile function. Replacing
this line
zipFile = createObject(java, java.util.zip.ZipFile);
With
zipFile = createObject(java, path.to.ZipFileVerifier);
I think the rest of the function code remains the same. Another alternative
would be to convert the above code into a CF function. Something like
cffunction name=verifyZipFile returntype=struct output=false
cfargument name=pathToFile type=string required=true
cfset var Local = structNew()
cfscript
Local.results = structNew();
Local.results.InputFile = arguments.pathToFile;
try {
Local.fis = createObject(java,
java.io.FileInputStream).init(arguments.pathToFile);
Local.zipin = createObject(java,
java.util.zip.ZipInputStream).init(Local.fis);
while ( Local.zipin.available() EQ 1 ) {
Local.zipin.getNextEntry();
}
Local.results.wasVerified = true;
Local.results.errorMessage = ;
}
catch (java.lang.Exception e) {
Local.results.wasVerified = false;
Local.results.errorMessage = e.message;
}
/cfscript
cfreturn Local.results
/cffunction
cfset status = verifyZipFile(c:\path\to\yourZipFile.Zip)
cfoutput
wasVerified = #status.wasVerified#br
errorMessage = #status.errorMessage#br
InputFile = #status.InputFile#br
/cfoutput

Re: java unzip :: verify file
I can't compile, reboot, etc. The server is a corprate one which I have no control over and hard to get done. I'll have to go with the CF Function. I'll package it together withthe unzip code in a CFC. Thanks for re-coding it! I'll compare what you did to the original code -- should give me a nice insight in Java vs CF. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:296635 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
Re: java unzip :: verify file
I'll compare what you did to the original code -- should give me a nice insight in Java vs CF. Yes. Keep in mind it is slightly different from the last example. That example extends the ZipFile class and calls the verify function inside the class's constructor. It's similar to extending a cfcomponent, then calling another function inside init(). Also the last example throws and exception if an error is encountered. The CF version does not. It catches any exceptions and returns the error message as part of the results structure. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:296639 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: java unzip :: verify file
Max has taken it up a notch now
You can use this class in replace of 'java.util.zip.ZipFile'
and it throws an error on init() that can be captured by ColdFusion if the
file is corrupt.
The downside though, is the zip is processed twice, once to verify it, and
then again for the normal processing. But compared to taking out jRun, I
think it is a small price to pay.

Re: java unzip :: verify file
FYI for the list.
It turned out that the issue AJ got was a Java bug for ZipFile. It
turns out that ZipFile doesn't handle corrupt zip files very well - It
throws an InternalError which will just kill JRun. :S
So, I updated my ZipVerifier to use ZipInputStream instead of ZipFile,
which will correctly catch the corrupt ZipFile exception.
