Best way to download files from Windchill Server to client

I'm looking to download a zip from my windchill server(temp location) to the client machine.

The zip was actually created as a result of an custom action.

So basically, when I click on the action a zip should get downloaded, that's my requirement.

Please suggest me your ideas or share me any existing solution.

Many thanks in advance.

Hi @MV_10441462 

depends how do you start your function. 

usually you get request and get the outputstream from it and flush (send) the data to the client as @avillanueva's example shows you. . 

 

here is short snip with a zipStream but you need to learn how to add files to the zip stream

 

 

HTTPResponse resp; // you need to get respons from commandBean or whereever HttpServletResponse response = nmCommandBean.getResponse(); 

ByteArrayOutputStream zipOut = new ByteArrayOutputStream();
CheckedOutputStream checksum = new CheckedOutputStream(zipOut, new Adler32());
ZipOutputStream zipOutputStream = new ZipOutputStream(new BufferedOutputStream(checksum));

InputStream contentStream = ContentServerHelper.service.findContentStream(appDatatToZip);
		// definice filename s cestou v zip
String fileZipEntry = appDatatToZip.getFileName();
addStreamToZip(fileZipEntry, zipOutputStream, contentStream); // annother sub method where the content is writen to zip

zipOutputStream.close();
		
OutputStream output = resp.getOutputStream();

resp.setHeader("Content-disposition", "attachment; filename=zipDownloadFile.zip");
resp.setHeader("Content-Type", "application/zip");

output.write(zipOut.toByteArray()); // zip stream written to the respons outputStream

output.flush();
output.close();

I did this with a JSP tied to that custom action:

BOMExportExcelUtility excelUtil=BOMExportExcelUtilityImpl.createBOMExportExcelUtility();
 //7. Sub-module create Excel File for user download
 response.reset();
 excelUtil.createExcelFile(response.getOutputStream(),sheet1,sheet2);
 ServletOutputStream outs = response.getOutputStream();
 response.setHeader("Content-type","application/ms-excel");
 String version=VersionControlHelper.getVersionIdentifier((Versioned)bom).getValue();
 if (version.indexOf('.')!=-1)
 version=version.substring(0, version.indexOf('.')); //just get first part
 
 String filename=bom.getNumber()+version;
 response.setHeader("Content-disposition","attachment; filename="+filename+".XLS");//should prompt for download
 
 excelUtil.writeFile();
 //8. Return response to user's browser session.
 outs.flush();
 outs.close();

This is the section where my code creates an XLS file and streams it back to the client. User downloads the file.

    Hi @MV_10441462 

    example  from @avillanueva is very good one how to download file.

    I would add that you need to write own sollution. 

     

    Create zip in java

    Collect files from Windchill  

    Add files to the zip

    push the zip stream to the client user
