Question: How to read a file in middle of a BPEL process?
Answer: Following are the ways to read a file in mid of a BPEL process:
1. Using File Adapter: Avoid using the file adapter to read a file. The read file adapter is used to trigger the BPEL process in most cases. So in this scenario, the file adapter is not a good choice. Also it needs to use correlation sets to read files in the middle of a process.
2. Using Embedded Java code: It can solve the problem but it is not recommended and also it is hard to maintain.
3. Using built-in XPath function: The good way to read a file in the middle of a BPEL process is to use the built-in XPath function --> ora:readfile.
Example:
1. Drag an Assign activity in the swim lane at proper place
2. Create an Assign rule using the ora:readfile("file location", "xml schema path") XPath function
3. Assign the result to a variable.
