'adb connect' sometimes adds an extra :4321 suffix

like below fixes the issue It seems that rebooting the tcpip server on the device fixes this. Steps to do this:
Plug the device in to a computer via USB Run 'adb usb' to connect to the device via USB Run 'adb tcpip 4321' to restart the tcpip server on port 4321 Unplug the device Run 'adb connect 192.168.1.x:4321' and it should now connect successfully.

Bash script: Copies image files from source dir to destination dir and adds an extra suffix on files with same file name

Bash script: Copies image files from source dir to destination dir and adds an extra suffix on files with same file name

wish helps you I have this script that copies image files from source directory to destination directory. There are some image files in the source directory that have the same name but different file size. This script also compares the two files with the same name using a stat command. Now, I want to add a string suffix e.g. IMG0897.DUP.JPG before the file extension to the files with the same file name that are going to be copied over to the destination folder. At the moment, my script adds the file size of the file to the file name. , I modified your scripte slightly.
code :
#!/bin/sh
SEARCH="IMG_*.JPG"
SOURCE=$1
DEST=$2
SUFFIX=DUP
test $# -ne 2 && echo Usage : phar image_path archive_path
if [ ! -e $1 ]
then  echo Source folder does not exist
fi
if [ ! -e $2 ]
then mkdir $2/
fi
# Execute the script.

    if [ "${SEARCH%% *}" = "$SEARCH" ]; then
        command="find \"$1\" -name \"$SEARCH\""
    else
        command="find \"$1\" -name \"${SEARCH%% *}\""$(for i in ${SEARCH#* }; do echo -n " -o -name \"$i\""; done)
    fi

    # Run the main loop.
    eval "$command" | while read file; do
        bn=$(basename "$file")
        bc=$(stat -c%s "$file")
        if [ -f "${2}/$bn" ] && [ "$bc" -ne $(stat -c%s "${2}/$bn") ]; then
            bc=$(echo ${bn}|cut -d. -f2)
            bn=$(echo ${bn}|cut -d. -f1)
            bn=$bn.$SUFFIX.$bc**
        fi
        if [ -f "${2}/$bn" ]; then
            echo "File ${2}/$bn already exists."
        else
            echo "Copying $file to $2/$bn"
            cp -a "$file" "$2/$bn"
        fi
    done
    exit 0
else
    echo "Error : Can't find $1 or $2"
    exit 1
fi
Spring Validation adds suffix to my message code

wish helps you I'm trying to implement form validation with Spring Validator, following these tutorials from dzone and mkyong. It seems the Validator method validate is called upon form submission, errors are thrown, but the message codes aren't the same that I specified. , add this to your configuration xml :
code :
<bean id="messageSource"
     class="org.springframework.context.support.ReloadableResourceBundleMessageSource"
     p:basename="classpath:messages" />
 @Bean(name = "messageSource")
    public ReloadableResourceBundleMessageSource reloadableResourceBundleMessageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasenames("classpath:messages");
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }

I wish did fix the issue. you must use fluent API for set relations and add ColumnAttribute to order keys :
code :
[Table("Artikel")]
public class Artikel
{
    [Key]
    [Column(Order = 1)]
    public string Artnr { get; set; }

    [Key]
    [Column(Order = 2)]
    public string ArtVersie { get; set; }

    public string ArtOmschrijving { get; set; }

    public Dossier Dossier { get; set; }

    public string Dossiernummer { get; set; }

}

[Table("Dossier")]
public class Dossier
{
    [Key]
    [Column(Order = 1)]
    public string Dossiernummer { get; set; }

    [Key]
    [Column(Order = 2)]
    public string Dossierversie { get; set; }

    [Required]
    public string Dossierreferentie { get; set; }

    [Required]
    public string Relatienr { get; set; }

    public ICollection<Artikel> Artikels { get; set; }
}
  protected override void OnModelCreating(DbModelBuilder modelBuilder)
  {
      base.OnModelCreating(modelBuilder);


        builder.Entity<Dossier>()
               .HasMany(x => x.Artikels)
               .WithOne(a => a.Dossier)
               .HasForeignKey(a => new { a.Dossiernummer, a.Artnr });


        builder.Entity<Artikel>()
        .HasKey(x => new {x.Artnr,x.ArtVersie});

        builder.Entity<Dossier>()
        .HasKey(x => new {x.Dossiernummer,x.Dossierversie});
  }

fixed the issue. Will look into that further following the link SAP - Go (golang) Support a made the code below: , after a lot of tests I found this palliative solution:
code :
package main

import (
    "crypto/tls"
    "database/sql"
    "github.com/SAP/go-hdb/driver"
    _ "github.com/SAP/go-hdb/driver"
    "log"
)

const (
    HOST     = "host"
    PORT     = ":port"
    USERNAME = "user"
    PASSWORD = "password"
)

func main() {
    c := driver.NewBasicAuthConnector(
        HOST+PORT,
        USERNAME,
        PASSWORD)

    tlsConfig := tls.Config{
        InsecureSkipVerify: false,
        ServerName:         HOST,
    }

    c.SetTLSConfig(&tlsConfig)

    db := sql.OpenDB(c)

    var id int
    var name string
    res := db.QueryRow("SELECT * FROM SCHEMA.TABLE LIMIT 1")

    res.Scan(&id, &name)

    log.Println("res ", id, name)

}
