File To be Zipped

Dear Friends
we are working on Data compression of a file for which I have to develop an Adapter Module. I have Created a EJB project in NWDS for the same and I need some library files like aii_af_mp.jarand aii_af_ms_api.jar which should be downloaded from SAP Service Market place. I am unable to download the files.
One more thing can anyone suggest me like are there any other possibility that a file can be compressed. Also suggest me like how can we use external testing tools to test and validate the data.
regards
chandra

Hi Chandra
These jar files can be found on your XI installation:
/usr/sap/<SYSID>/DVEBMGS00/j2ee/cluster/server0/bin/services
/usr/sap/<SYSID>/DVEBMGS00/j2ee/cluster/server0/bin/ext
You can also do a search for the file names.
ejb20.jar can also be downloaded from SUN.
This may help you

Reading a Compressed File from a ZIP File, which is an entry of ZIP File

Hello, Experts,
Would it be possible somebody to help me with code example for the following problem?
I want to read a compressed file from a ZIP file, which is an entry of ZIP File, without extacting/writing files on file system. Is this possible?
Lets say we have a ZipFile1. There is ZipFile2 inside ZipFile1. And inside ZipFile2 is FileA. The scenario is reading FileA without extracting on file system.
Thank you in advance for your help.
Cheers
RADY

The classes you want to be using are java.util.zip.ZipInputStream and and ZipEntry from the same package. Construct the ZipInputStream with the input you have for the outer zip. Loop with ZipInputStream.getNextEntry until you find the inner zip you're looking for - that method returns a ZipEntry, and you get the name of the zip entry with ZipEntry.getName. Read the ZipInputStream from that point into some buffer, and read that buffer into a new ZipInputStream - rinse and repeat until you have the contents of the file in the zip in the zip...

Formatting lost in the text file, got after zipping.

Hello ABAP gurus,
A text file has to be zipped .I have used the class method CL_ABAP_ZIP-SAVE() to create a zip file in the application server. The zip file is double clicked and the text file is opened.
The formatting is lost in the text file, got after zipping.
Please let me know how I maintain the formatting in the zip file.
Thanks.

Problem with compressing unicode file names in zip file

Hi Everyone,
I have a problem while compressing the unicode file name in a zip file. I used the below code for compressing the unicode files.
String[] source = null;
// C:\\TestData\\unicode_filename.txt : unicode_filename.txt is the file created in japanesse language
source = new String[] {"C:\\TestData\\temp_properties.xml","C:\\TestData\\unicode_filename.txt" };
byte[] buf = new byte[1024];
// Create the ZIP file
String target = "C:\\TestData\\target.zip";
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(target));
// Compress the files
for (int i = 0; i < source.length; i++)
     FileInputStream in = new FileInputStream(source);
     // Add ZIP entry to output stream.
     String fileName;
     File tempFile;
     ZipEntry zipEntry = new ZipEntry(source[i]);
     fileName = zipEntry.getName();
zipEntry = new ZipEntry(fileName);
zipEntry.setMethod(ZipEntry.DEFLATED);
getUTF8Bytes(source[i]);
// here I'm unable to find the unicode files and not able to understand.
out.putNextEntry(zipEntry);
// Transfer bytes from the file to the ZIP file
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
// Complete the entry
out.closeEntry();
in.close();
// Complete the ZIP file
out.close();Please help me how to fix this issue.

How to read/unzip a specific file within a zip file

Hi,
I have a file within a zip file that contains a timestamp - I want to read this timestamp and then create a destination directory for the remaining zip files to be unzipped into. Since I know the name of the file with the timestamp in it I thought I could create a zipfile and use getEntry to get the entry but then other than getting the size and name of the file I can't do much more with it like read it unless I use a stream (zipinputstream) instead of a file (zipfile) - do I have this right?
Does this mean to get the content I would have to loop through possibly all the files using the stream until I come across the one I want - then get the timestamp and loop through them all again to write them to the destination directory? Or am I reading this wrong - seems a bit round about.
Any suggestions would be greatly appreciated.
Thanks

this works though - and you don't have to loop through all the files - just use the ZipFile:
ZipEntry ze = zipfile.getEntry("path/to/file");
BufferedReader br = new BufferedReader(new InputStreamReader(zf.getInputStream(ze)));
line = br.readLine;Thanks!

Linking to PDF files in HTMLResources.zip file with Windows 8.1 Viewer

I have followed the instructions from 'DPS Tips' regarding creating a HTML Resources folder and compressing the PDF files etc... It works on IOS Viewer but it doesn't work on Windows 8.1 Viewer.
Is linking to PDF files in HTMLResources.zip file support for Windows Viewer?
Thanks

Hi Bob,
I do not understand, you're telling me that if I set my default browser to Chrome on Windows 8.1, the Viewer works with, or does the Indesign Folio Preview works?

How to unzip a zip file within another zip file

I've got code that successfully processes a file within a zip file.
But now the zip file can also contain other zip files. How can I
process a zip nested within a zip without actually extracting the
files? It looks like I need a ZipFile object to be able to take
advantage of the zip classes for reading zip entries. But the
ZipFile methods want as an argument an actual file, as opposed
to some object in memory. I can read the 'inner' zip file into a
ZipInputStream object, but then how do I make that available for
processing as a ZipFile? I've searched all over and cannot find
anything anywhere that talks about working with nested zip files.
Does anyone have any sample code that does this? Thanks!

I have successfully done it.
You cannot have the code - it is proprietary.
However here are a few pointers:
o Use ZipStreams rather than ZipFile.
o ZipStream is just a filter on a stream, so you can have a zipstream open, read a ZipEntry, then ask for a substream for the stuff up to the next ZipEntry. Put a second ZipStream on that substream.
o As I recall you have to watch out that your inner ZipStream does not do a close. (Everything will get closed.) Instead, there is another ZipStream method that will close without closing all the underlying streams.
Hope this helps.

IE or Contract Management v13 thinks my DOCX file is a zip

When trying to open an attachment IE or Contract Management v13 thinks my DOCX file is a zip. This started last Thursday. Outta the blue. We’ve been searching for a days now for a solution. Nothing has helped. I have a few hundred users all with various combinations of applications on their boxes. XP PRO, Windows 7, Office; 2007, 2010, WordPerfect 5.1 files work just fine. :)

We are having the same problem and are wondering whether you found a solution. A workaround is to disable MIME handling in IE (this is what Oracle support will suggest), but this is far from ideal as it does compromise security slightly.
The problem arises when WebLogic (or JBoss, WebSphere....) sends the file to your browser. It marks the file as Content type "application/octet-stream" instead of identifying it as a MS Word 2010 document. This causes IE to try to identify the type itself. First it checks the extension of the file and looks in the registry to see what's there. If it finds an entry, it then reads the first part of the file to see if the content matches what the registry says. Something appears to be broken in the way IE identifies Word 2007+ files, causing it to identify them as .zip files. Users are then prompted to save the file to their desktop.
Word 2007+ files actually ARE zip files under the hood, but until recently we had no problem with them. There appear to be three possible routes to resolve this issue.
One, take Oracle's "pass the buck" advice and disable MIME handling in IE so that IE no longer tries to identify the file (registry hack set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_MIME_HANDLING\iexplore.exe to 0). This bypasses the problem and introduces security holes to your workstation configuration.
Two, configure your Java application server to send the files with the correct content-type header. I can't find a way to do this in WebLogic so far as you have to modify the web.xml file, which is created by the application installation/deployment. Oracle Primavera CM support has yet to respond to my request on this other than to say "consult WebLogic support". Oracle WebLogic's support will (as they have in the past) tell me it's application specific and to consult Oracle CM support. Neither support group seems to be able to support Oracle's products. (Dear Oracle, please get your act together. You own both products and should be embarrassed by the lack of customer service here.)
Three, figure out why IE is failing to match up the 2007+ file types with the file content. We're assuming a recent patch did this, but haven't identified which one. In any event, we will probably not be allowed to roll back a security patch to fix this.
Anyway, I hope this helps you. I have a case open currently, as well as another post in the forums.
