read webservice filename tag & pull the file from file location

[Former Member]

Hi,

PI system has exposed a web service out of the following structure for the outside party to call

<MAT>

<doc type>pdf</doc type

<subnumber>1234</subnumber>

<id>45ABC<id>

<matno>ABCD</matno>

<filename>transaction1.pdf</filename>

</MAT>

When the outside party submits a web service request, I have to read the <filename> value (transaction1.pdf) and get the file from the file location which is local and convert the file to byte array.

How do I do this in message mapping or java mapping? Any help is greatly appreciated

thx

Hi. Michael.

You need another scenario to red the PDF file.

You can use a java mapping, to read the PDF file.

Also you can check this document.

I don't think I can use another scenario because it has to be in the same scenario where in webservice request comes to PI and PI use a look up file as shown in the below link to get the file from the ftp location

File Lookup in UDF - Process Integration - SCN Wiki

Can I use this for PDF? And also how would the code looks like in my case for reading pdf and convert to byte array.

thanks

Hi. you can use this UDF to convert the PDF to byteArray.

public static byte[] loadFile(String sourcePath) throws IOException {
        byte[] buffer = new byte[8192];
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        InputStream inputStream = null;
        int bytesRead;

        try {
            inputStream = new FileInputStream(sourcePath);
            while ((bytesRead = inputStream.read(buffer)) != -1) {
                baos.write(buffer, 0, bytesRead);
            }

        } finally {
            if (inputStream != null) {
                inputStream.close();
            }
        }
        return baos.toByteArray();
    }

Thanks Luis for the reply. I am not efficient in writing java program in udf.

can you please write the full java code for udf for connecting to ftp server url and then get the file using file name and convert to byte array. It would be really helpful

thx
