We have NAS share,  have to find given user(dmadmin) exist on permission entry all sub folders from a folder in NAS using java, see attachment

Performance of application is every important aspect, thanks for getting your thoughts in the book, hopefully will help people great extent.

Hi All,
We have web application accessing through IE 11 using Load balancer url, certificates are deployed on Load balancer, see warning message with JRE Java 8 update 51, whereas the application works fine with Java 8 update 25, attached screen shots of sample certificates. Please advice what might causing.


In working case(Java 8 update 25), Certification Authority is connected using proxy url, whereas in issue case(Java 8 update 51) Certification Authority connected directly.

1. Below is Java console trace with Java 8 update 25
network: Connecting http://ocsp.verisign.com/ with proxy=HTTP @ xxweb.xx.xxx/xx.xxx.xxx.xx:9999
security: OCSP Response: GOOD



2. Below is Java console trace with Java 8 update 51.

code was working for many years with 1K, some kind of configuration changed on samba server, I disabled dfs property in jcifs, looks working in non production environment, yet to verify in production, will keep posted once verified. Thanks for helping.

If we map source drive (\\xxx.xx.xx.xx\abcd95\D\NJ$) from target machine (aaaaaa.bbb.ccc), using window copy option transfer is quick 160MB takes 3 sec. Whereas this functionality we are doing from code implemented using JAVA API with SAMBA protocol (jcifs-1.3.17.jar) takes longer time. This implementation been working fine 8+ years, no change in implementation, since recently performance degraded, transfer take 40+ minutes, sometime transfer fails. Is it some would have changed on samba server/configuration?, please advise.

Hi All,
I would like to have advice on multiple issues, code snippet java code.

void test(){ SmbFile sFile = null; NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(activeUserDomain, activeUserID, activePwd); sFile = new SmbFile("smb:"+absoluteFilePath.replaceAll("\\\\", "/"), auth); File inFile = new File(tempZipDir,zipFileName); inFile.createNewFile(); DataOutputStream outZ = new DataOutputStream(new FileOutputStream(inFile)); InputStream inZ = sFile.getInputStream(); copyStreams(inZ,outZ); } private static final void copyStreams ( InputStream in, OutputStream out ) throws IOException { byte [ ] buffer = new byte[1024]; int len; while ( ( len = in.read(buffer)) >= 0 ) { out.write( buffer, 0, len ) ; } in.close() ; out.close() ; }

1. above snippet of code setup locally, worked one day but later throws below exception, what might causing?

java.net.ConnectException: Connection timed out: connect at java.net.DualStackPlainSocketImpl.connect0(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:79) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:200) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:182) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:579) at java.net.Socket.connect(Socket.java:528) at java.net.Socket.<init>(Socket.java:425) at java.net.Socket.<init>(Socket.java:208) at jcifs.smb.SmbTransport.ssn139(SmbTransport.java:226) at jcifs.smb.SmbTransport.negotiate(SmbTransport.java:288) at jcifs.smb.SmbTransport.doConnect(SmbTransport.java:353) at jcifs.util.transport.Transport.run(Transport.java:240) at java.lang.Thread.run(Thread.java:745)

2. Basically I am trying to trouble shoot performance issue, same code have been working for years i.e. to copy zip file(3KB to 800MB) from samba server to appserver but since recent time copy function takes long time for a give file, please advice what might cause?

We have below code to copy a zip file > 170GB from NAS drive, takes longer time, please advice to improve performance.

NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(activeUserDomain, activeUserID, activePwd); SmbFile sFile = new SmbFile("smb://199.bb.cc.dd/abc/d/zzz$/11_122005.zip", auth); //creates target zip file, in specified location File inFile = new File(tempZipDir,zipFileName); inFile.createNewFile(); // Create Streams DataOutputStream outZ = new DataOutputStream(new FileOutputStream(inFile)); InputStream inZ = sFile.getInputStream(); // move the streams over byte [ ] buffer = new byte [ 1024 ] ; int len; while ( ( len = (inZ.read(buffer)) >= 0 ){ outZ.write( buffer, 0, len ) ; }

help me, how can we create an image on chart in pptx

I have web service client generated from wsdl2jave of axis2-1.4.1, we are getting an error on calling webservice operation, i have manually set timeout at one of the operation invocation, that looks fine , but we have call so many places, do i need to set time every place.
I am not sure code i have to set time is correct, please advice how to over come the issue, web service has been deployed on WAS.

here is the code added to set timeout
int timeOutInMilliSeconds = 3 * 60 * 1000; // Two minutes stub._getServiceClient().getOptions().setProperty(HTTPConstants.SO_TIMEOUT, new Integer(timeOutInMilliSeconds)); stub._getServiceClient().getOptions().setProperty(HTTPConstants.CONNECTION_TIMEOUT, new Integer(timeOutInMilliSeconds)); //end here GetPermittedTypesResponse response = stub.getPermittedTypes(get); permittedTypes = response.getReturn();

I have a below code to lookup LDAP to find userprincipal name using login name, works fine, look up to default ldap server, if i want to provide ldap server name, port and principal user name and password, what code i have to use, it will be great help.


public static void main(String args[]){ String value = toUpn("us\\vittalm"); System.out.println(" value = "+value); } private static String toUpn(String nt4Name) { NativeLongByReference nSize = new NativeLongByReference(); char[] translatedName = new char[512]; nSize.setValue(new NativeLong(512)); if (Secur32bis.INSTANCE.TranslateName(nt4Name, new NativeLong( EXTENDED_NAME_FORMAT.NameSamCompatible), new NativeLong( EXTENDED_NAME_FORMAT.NameUserPrincipal), translatedName, nSize)) { return Native.toString(translatedName); }

We have 2 sets of java client files generated from wsdl i can see some syntax difference between generated by somebody else & myself. what i have to do, so i my java code syntax will match

below are difference marked in red & bold

somebody java client code syntax

public enum AccessType {

PERMIT, RESTRICT, REQUIRE_GROUP, REQUIRE_GROUP_SET;

public String value() {
return name();
}

public static AccessType fromValue(final String v ) {
return valueOf(v);
}

}


my java client code syntax

public enum AccessType {

PERMIT,
RESTRICT,
REQUIRE_GROUP,
REQUIRE_GROUP_SET;

public String value() {
return name();
}

public static AccessType fromValue(String v) {
return valueOf(v);
}

Ok, from Tony comment, modified my code as below

getLocalTime(String timeInServer, int timezone){
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss a");
String newdate = null;
Calendar cal = Calendar.getInstance();
cal.setTime(sdf.parse(date));
sdf.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles"));
String newdate = sdf.format(cal.getTime());
System.out.println("before = "+date);
System.out.println("after = "+newdate);
return newdate;
}

I have hard coded timezone value as America/Los_Angeles to get user TimeZone object. my question here is how i can find time zone value which i have hard coded(America/Los_Angeles), is there any java script method available or httprequest will have.
thanks

Users are accessing web application from different countries, application is deployed in Germany. code is getting time in germany time zone, in application getting timezone offset(difference server to client) adding / subtracting to server time. looks due to daylight saving for some records time show difference than local time expected.

code i have is, it doesn't handle daylight saving, if i want to handle also daylight saving for different countries, what i have to do.

getLocalTime(String timeInServer, int minutes){
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss a");
String newdate = null;

Calendar cal = Calendar.getInstance();
cal.setTime(sdf.parse(timeInServer));
cal.add(Calendar.MINUTE, minutes);
newdate = sdf.format(cal.getTime());
return newdate;
}

It worked using dateformat & calender, but as Winston mentioned we do see issue with daylight saying, please suggest how to handle.

I have date in string variable, i have to add/subtract minutes from it, please adivce , how i could do in java 1.5
sample data
String olddate = "12/16/2010 4:58:29 PM"
String minutes1 = "300"
i would like to get value as below for above data
String newdate ="12/16/2010 9:58:29 PM"


Thanks
