Hi Experts,

Could you help me how to find below special charcters "" in JAVA and Shell Script please.

This appers just of the first name of a person. Since we are not identifying this...this slips through our process and fails at the end of complete process. if we could identify this as part of the first parsing step. it would save lot of reprocessing time and defects etc.


This is what I see in a XML file
Firstname  Lastname


Same above character in a CSV file after the complete process failed
Firstname � Lastname

BufferedReader input = null;
            int numLines = 0;
            String[] lines = null;
            try {

                  input = new BufferedReader(new FileReader(lFilePathStr));
                  try {

I have a file which has multiple ST* sets. Is there a way to tokenize to get these sets into string Builder or any of the similar kind? I dont want to loop through each and every line to combine all the lines of the ST sets. The idea is once I get the ST sets then I can combine the header(ISA+GS) and ST with trialer(IEA+GE) to form one proper recordset. PFA  is the file.

I am planning to start with getting all the file into one string builder using the following code and then proceed stripping off the pieces I need to rebuild the set desired. PFA also the individual sets desired. Please note I have the code to generate the individual sets but I need it withough reading though and looping through each line. Need some kind of tokenizer.

 

InputStream is = new FileInputStream("manifest.mf");
BufferedReader buf = new BufferedReader(new InputStreamReader(is));
        
String line = buf.readLine();
StringBuilder sb = new StringBuilder();
        
while(line != null){
   sb.append(line).append("\n");
   line = buf.readLine();
}
        
String fileAsString = sb.toString();
System.out.println("Contents : " + fileAsString);

I keep getting this error: Java was not found or is executable at the specified path, when putting in the Java Dir.  I have verified this 10 times over yet I still cant figure out why Drupal cant find the Java application...

Hi Folks,

I have an EDI file, which I need to sort and segregate the Transaction sets and transfer each transaction set into an FTP folder as a separate file. In the attachments I have "File A" which is the actual input file and "File B" shows format after the sort to show the individual transaction sets and finally 3 files "Output 1" , "Output 2" and "Output 3" which have to be extracted out of the File B and have to be sent to an FTP server. The idea is to directly extract the Output 1 , 2 and 3 from File A. I have shown the File B to depict what I meant by Transaction sets.

Each Transaction set consists of the following components in that order. Please check the file "File_A_components" which shows the highlighted components from the "File A" for reference.  I would need suggestion on how to generate Output 1, 2 and 3 separate files into an FTP server using Java. I am an amateur in JAVA. So please provide as detailed as possible.

Transaction Set components
Header
ST set
Trailer

Regards
Kalyan.

Hello Experts,
I have built few HTTP 1.1 listen service mocks using SoapUI and CA DevTest tools. Every request to the service from a client like Postman is established as a new connection. Inserting a custom header Connection:Keep-Alive into the request and also the response is not making any difference. Can I know is there more to be done to have the socket open for successive connections happening within a second?

Thanks.
