This exception is thrown from wso2 mobileupload.jag

var path = process.getEnv("PWD")+"/repository/deployment/server/jaggeryapps"+meta.path;

I print the process.getEnv("PWD"), it always return null. So how can i fix this issue?

The whole mobileupload.jag is as following:

<%
(function(){
var mam_config = require('/config/mam-config.json');
var log=new Log();
var makeid= function()
{
    var text = "";
    var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

    for( var i=0; i < 5; i++ )
        text += possible.charAt(Math.floor(Math.random() * possible.length));

    return text;
}
var getExtension = function(file){
    var path = file.getName();
    var index = path.lastIndexOf('.');
    var ext = index < path.length ? path.substring(index + 1) : '';
    return ext;
}
var getFileOnly = function(file){
    var path = file.getName();
    var index = path.lastIndexOf('.');
    var name = index < path.length ? path.substring(0,index) : '';
    return name;
}
var saveFile = function(file){
    if(file!=undefined){
        var file_n= file.getName()
        if(file_n==""){
            return "";
        }
        var uid= makeid();
        var file_name = mam_config.filePreciseLocation+uid+file_n;
        file.saveAs(file_name);
        return file_name;
    }
    return "";
}
function mergeRecursive(obj1, obj2) {
    for (var p in obj2) {
        try {
            // Property in destination object set; update its value.
            if (obj2[p].constructor == Object) {
                obj1[p] = MergeRecursive(obj1[p], obj2[p]);
            } else {
                obj1[p] = obj2[p];
            }
        } catch (e) {
            // Property in destination object not set; create it and set its value.
            obj1[p] = obj2[p];
        }
    }
    return obj1;
}
var file = request.getAllFiles().file;
var meta = {};
if(file==undefined){
    //return error
    response.sendError(500);
}else{
    meta.path = saveFile(file);
    meta.path = '/publisher' +meta.path;
    var ext = getExtension(file);
    if(ext=="ipa" || ext =="apk"){
        var zipFileReading = new Packages.com.wso2.mobile.mam.manifestUtils.ZipFileReading();
        var path = process.getEnv("PWD")+"/repository/deployment/server/jaggeryapps"+meta.path;
        try{
            if(ext=="ipa"){
                var d = zipFileReading.readiOSManifestFile(path, getFileOnly(file));
                log.debug(d);
                var information = JSON.parse(d);
                mergeRecursive(meta,information);
            }else if(ext=="apk"){
                var d = zipFileReading.readAndroidManifestFile(path);
                log.debug(d);
                var information = JSON.parse(d);
                mergeRecursive(meta,information);
            }
            print(meta);
            log.debug("Successfully discovered");
        }catch(e){
            log.debug("Uploaded file is corrupted");
            print({"ok" : false, "message" : "Validation failure", "report" : {"failed" : true, "name" : ["Uploaded file is corrupted"]}})
        }
    }else{
        print({"ok" : false, "message" : "Validation failure", "report" : {"failed" : true, "name" : ["Invalid Filetype - Uploaded file is not an archive"]}})
        return;
    }   
}
}());

Thanks in advance!

Answer 1

Please change

process.getEnv("PWD")

to

Packages.java.lang.System.getProperty("carbon.home") 

in mobileupload.jag

This issue is fixed in 1.1.0 release of WSO2 Mobile EMM

Answer 2

I solved this issue by a workaround solution, i added a system environment variable named "PWD", with the value set to "C:/wso2/wso2mobileserver-1.0.0" (MOBILE_SERVER_HOME_DIRECTORY).
