Not necessarily catch, a try must be followed by either catch or finally block. Example import java.io.File; public class Test{ public static void main(String args[]){ System.out.println("Hello"); try{ File file = new File("data"); } } } Output C:\Sample>Javac Test.java Test.java:5: error: 'try' without 'catch', 'finally' or resource declarations try{ ^ 1 error
A checked exception is an exception that occurs at the time of compilation, these are also called as compile time exceptions. These exceptions cannot simply be ignored at the time of compilation; the programmer should take care of (handle) these exceptions. if you use FileReader class in your program to read data from a file, if the file specified in its constructor doesn't exist, then a FileNotFoundException occurs, and the compiler prompts the programmer to handle the exception. Example import java.io.File; import java.io.FileReader; public class FilenotFound_Demo { public static void main(String args[]) { ... Read More
You need to set up a workflow engine and then customize event generation. Next is to write down a Java service to connect to SAP system using Java Connector and then register a RFC server. For this, you have to follow steps:Navigate to Transaction SM59 -> Expand TCP/IP connections directory and click on Create (F8).In the RFC destination field, enter the name of the RFC destination system. Next is to set the connection type to T (Start an external program through TCP/IP).Next is to provide a Function Module handler that can be called using tRFC from SAP system -> Next ... Read More

A java archive file is a file format/ archiving tool which contains all the components of an executable Java application. All the predefined libraries are available in this format. To include any of these (other than rt.jar) in to your project you need to set the class path for this particular JAR file. You can create a JAR file using the command line options or using any IDE’s. Creating a Jar file You can create a Jar file using the jar command as shown below. jar cf jar-file input-file(s) Let us consider an example, create a Sample Java ... Read More
A native method in Java is a method whose implementation is written in other languages such as c and c++. The ‘native’ keyword is used before a method to indicate that it is implemented in other language.
Yes, this is feasible. You can create simple transformation for XML in ABAP. You can also use cl_proxy_xml_transform to transform data between XML and ABAP. Let us say that you have created ABAP proxy using T-Code: SPROXY or it is generated via WebService generation utility, you can use utility class “cl_proxy_xml_transform” to convert data of the ABAP to XML format or also from XML → ABAP.
A native method is the one whose method implementation is done in other languages like c++ and Java. These programs are linked to Java using JNI or JNA interfaces. The difference between normal method and native method is That the native method declaration contains native keyword and, the implementation of the method will be other programming language. Example Tester.java public class Tester { public native int getValue(int i); public static void main(String[] args) { System.loadLibrary("Tester"); System.out.println(new Tester().getValue(2)); ...

I don’t think it can be automated so that configuration is not copied to the database. Try checking SAP Transport and Change Management detail, it could be possible by making some changes in Transport configuration.
There is no straightforward way to do this. But it is possible to run a Python program and parse the output. You can execute any shell command using the function system (cmd, flag). The second argument is optional. If it is present, the output of the command is returned by system as a string. If it is not supplied, any output from the command is printed, with the standard output filtered through the pager. For example,output = system ("python /path/to/your/python/script.py", 1)
