Java call in OSB.

Question

I am sorry if this seems like a basic question but I am new to OSB and middleware.
I have a Java class that transforms a CSV to XML that I need to call from OSB.
OSB needs to pick up the csv file from a folder, pass the file name into the java class, then notify another process that the xmls have been created.
Something like that.
Any help would be appreciated.

Answer 1

Create a Proxy Service like this:
Service Type      Messaging Service
Request Message Type      
Text           
Response Message Type      
None           
Protocol      file
Endpoint URI      file:///c:/temp
Get All Headers      No Headers      
File Mask      *.txt
Polling Interval      60
Read Limit      10
Sort By Arrival      false
Scan SubDirectories      false
Pass By Reference      false
Post Read Action      delete
Stage Directory      file:///temp/stage
Error Directory      file:///temp/error
Request encoding      utf-8
Message Handling Configuration      
Transaction Required      Disabled
Same Transaction For Response      Disabled
Content Streaming      Disabled
(they are almost all default values)
When you log $body, you will see that it contains your file.
Just pass $body/* to a Java callout and do your transformation to XML.
MFL is an optional, but since you want to reuse your Java code, just do the Java Callout.
I am sure that if you google (or search on youtube) for
OSB java Callout
you will find plenty of tutorials.
Just define a Java static method
public static void processFileContent(String fileContent)
If you need to return your XML to OSB for further processing, you should return XmlObject rather than void.
I can teach you how to transform a XML String into a XmlObject
