Unzip using VCO

[LVSCLOUD]

Hi,

Does anybody have any sample code on how to unzip using VCO? I found a very promising blog post at might-virtualization, however the example is now missing.

[Andreas_Diemer]

Sorry

I Look for my saved Code and will provide

Hi Andreas,

Did you manage to find this code?

[Burke-]

Wouldn't it be easier to use a command line tool that unzips files, then use the "command" object in vco to call that tool with the name of the archive to be unzipped and any other command line switches??

[Subnet88]

That would probably work, but I want to keep my VCO appliance as close to pristine as possible.  Do you have any documentation as to what files are overwritten during an automated update of a VCO appliance? If I could be sure that no other packages would be removed, it would not be an issue to tackle this problem in this manner.

Could the vix plugin which is a fling on labs.vmware.com be useful in  your case but transferring the file over the the guestvm and running a  suitable script or command there also via the vix workflow . Apologies  if I misunderstood your query

[Subnet88]

Thanks for the idea Michael, but the idea is to upload am OVA file via a WAvemaker web portalm have the VCO server unzip it and feed it into the upload an ovf workflow for vCloud Director.   I could be making this whole thing over-Complex, so please tell me if you think so.

Hi!

In that situation: Where is your Wavemaker frontend running?

Maybe it was another idea to let the frontend to the unzipping, and give the unzipped ova data to the workflow...

Unfortunately, my Java knowledge is nearly nill, and while actively developing, I do not have time to learn. When I saw the blog post with unzipping in VCO itself, I thought my issue was solved.

[mobcdi]

The standard vix worflows listed when i installed the plugin seem to  operate on files, folders on guest vm's with only 1 workflow to copy a  file from vCO server to a guest but I'm just scratching the surface of  vCO so wouldn't be the best to advise you, hope more knowledgeable  members can help you out.

[Subnet88]

Unfortunately nothing the VIX plugin can do for me will help.

I have been able to peacemeal together SOME code, and can successfully call the zip java class, but am unable to call the java.io.file class as there is already a file class being handled by VCO.

From vco, what would be the best method to create a file, and write to the file from a java stream?

below is my current code

I currently fail on "destinationFilePath =  new java.io.File(zipPath,entry.getName());" with "TypeError: [JavaPackage java.io.File] is not a function, it is org.mozilla.javascript.NativeJavaPackage."

                        /*
                         * STEP 1 : Create directory with the name of the zip file
                         *
                         * For e.g. if we are going to extract c:/demo.zip create c:/demo
                         * directory where we can extract all the zip entries
                         *
                         */
var length = strZipFile.length
                        var fSourceZip = new File(strZipFile);
                        var zipPath = strZipFile.substr(0, length-4);
                        var temp = new File(zipPath);
                        temp.createDirectory();
                        System.log(zipPath + " created");

                        /*

                         * sub-directories
                         *
                         */
                        var zipFile = java.util.zip.ZipFile(strZipFile);
System.log("Called zip java class")
                        var e = zipFile.entries();


                        while(e.hasMoreElements())
                        {
                                var entry = e.nextElement();
                                destinationFilePath =  new java.io.File(zipPath,entry.getName());

                                //create directories if required.
                                destinationFilePath.getParentFile().mkdirs();

                                //if the entry is directory, leave it. Otherwise extract it.
                                if(entry.isDirectory())
                                {
                                        continue;
                                }
                                else
                                {
                                        System.log("Extracting " + destinationFilePath);

Not sure if this is going to help you but the VMware Lifecycle Manager Application has a plug-in with the scripting objects to unzip. (zipreader) The issue is of course that LCM has is EOL and I am not sure it can be found anywhere.

This was added to LCM because it was missing in vCO (Back then it was a quick fix for the LCM team to add it instead of requesting a feature in vCO and wait for the next release).

I can talk with the VCO product manager about bringing this feature in vCO but it will not help you as the next vCO release has been frozen.

Christophe.

[Subnet88]

Thanks Christophe,

It would be great if you could put that feature request in for me.

In the mean time,  Would you be able to reach out internally to see if anybody else has had to come up with a work-around?

I have located LCM vmoapp files here: https://my.vmware.com/web/vmware/details?productId=32&downloadGroup=VLCM120

The problem is I do not know how you can get a license number for it. If it is still possible to get one (i.e eval license) here is the process:

[if you could not source a LCM license the plug-in will not be installed when restarting the server]

• Download.
• (No need of installing the vmoapp file since it will contain a lot of things you do not need)
• Rename the vmoapp .zip
• Unzip
• In the configurator install vmware-vmosdk-lcm.dar
• Select Same as vCO for the plug-in config (this will create a bunch of tables in your vCO database - alternatively you can set a different one)
• In the licenses tab, go to the plug-in license and enter the LCM serial number.
• Restart the server.

Next week I will be at VMworld and will discuss the inclusion of this feature in the next next vCO release with the product Manager.
