JavaScript is a dynamic computer programming language. It is lightweight and most commonly used as a part of web pages, whose implementations allow a client-side script to interact with the user and make dynamic pages. It is an interpreted programming language with object-oriented capabilities.To learn JavaScript, refer to the following tutorial. It explains the below-given JavaScript concepts perfectly.OverviewSyntaxVariablesOperatorsLoop ControlFunctionsEventsCookiesDialog BoxesIt also explains the following advanced topics with live examples.Error HandlingValidationsAnimationMultimediaDebugging
Java provides ImageIO class for reading and writing an image. To convert a byte array to an image.Create a ByteArrayInputStream object by passing the byte array (that is to be converted) to its constructor.Read the image using the read() method of the ImageIO class (by passing the ByteArrayInputStream objects to it as a parameter).Finally, Write the image to using the write() method of the ImageIo class.Exampleimport java.io.ByteArrayOutputStream; import java.awt.image.BufferedImage; import java.io.File; import javax.imageio.ImageIO; public class ByteArrayToImage { public static void main(String args[]) throws Exception { BufferedImage bImage = ImageIO.read(new File("sample.jpg")); ...

As mentioned in exception message, it seems that the function module tries to access GUI related function and it doesn’t support BAPIs. So it seems to be a custom RFC module or there is some bug in SAP coding and you should open a support ticket with SAP.Also, you shouldn’t use GUI services in non-GUI operations, and it is not suggested to use class cl_gui_frontend_services and functions GUI_* and you should use OPEN_DATASET FOR INPUT/OUTPUT instruction in RFC function.
The issue lies in the class you are using for making a method call. This class is basically making RFC callback with the help of SAP GUI. SO, when you are using the function builder, it works well because it has an SAP GUI connection present.But when you are using an external system, the GUI is missing and it doesn’t works. What you can try is to use some other method which does not have an RFC callback and thus will not have any problem. Try to use ‘create_with_table’ in place of your used method.
An array is a data structure/container/object that stores a fixed-size sequential collection of elements of the same type. The size/length of the array is determined at the time of creation. The position of the elements in the array is called as index or subscript. The first element of the array is stored at the index 0 and, the second element is at the index 1 and so on. Each element in an array is accessed using an expression which contains the name of the array followed by the index of the required element in square brackets. You can access an ... Read More
As per my understanding, the key difference between two statements is that in first you are reserving memory space for storing 5 lines of the customer_tab table.If you consider performance, the 2nd statement should be better.
I would recommend to use LDAP_READ instead of LDAP_SEARCH and you will see thumbnail photo should be available in a convenient form to be from “XSTRING”.LDAP_SEARCH is mentioned as obsolete in SAP documentation. To see full documentation of this FM, you can use T-code SE37 to open Function Builder. Navigate to Goto ->Documentation -> Function Module Documentation.Function Module: LDAP_READ Function Group: FSLDAP_EXTProgram Name: SAPLFSLDAP_EXTINCLUDE Name: LFSLDAP_EXTU01
The answer lies within the exception message itself. The connection string that you are using to connect to the Business object server is wrongly configured. Check for each parameter, you will find something must be wrong and hence why you are receiving this error message.
