Apache POI The Apache POI Java APIs is used for manipulating various file formats based upon the Office Open XML standards (OOXML) and Microsoft's OLE 2 Compound Document format (OLE2).
But it does not support reading RTF. Please find the information that we got from forums.
No, POI has no provisions for reading RTF. But the basic structure of RTF isn't complicated. If you spend some time with the specification (such as there is) and study a few simple RTF files, you should be able to write code that parses the file contents and extracts the actual text.
No. RTF is not an OLE 2 Compound Document Format (hence the header error), nor is it a closed format, nor even binary and there are plenty of libraries that can read/write it. POI only covers "nitch" formats (OLE 2 Compound Document based).
JODConverter is supporting DOCX as input but not as output format.
Please find the error trace when we tried converting RTF to DOCX.

Exception in thread "main" java.lang.IllegalArgumentException: unsupported conversion: from Rich Text Format to Microsoft Word 2007 XML
docx4j docx4j is an open source Java library for manipulating OpenXML WordprocessingML documents, released under the Apache software licence.
It supports creating, reading and saving DOCX files and export them to PDF/HTML. But, it does not help in reading RTF file.
We have also come across utilities like Docmosis, Java2Word, javadocx and iText. But none of them helped in converting RTF to DOCX.
Any suggestion on this is much appreciated. Thanks
What is the reason for wanting to do this conversion? I think every application that can open DOCX can also open RTF, so you're not gaining anything. But you're actually losing something because not every application that can open RTF can open DOCX.

Hi Ulf Dittmer,
We are currently reading xml and creating RTF using Java and delivering to user. Now we have requirement to deliver in DOCX format, so we thought of creating RTF and use any utility to convert to DOCX and deliver it to user

OK, just so long as you're clear that DOCX is less widely usable than RTF.
Converting documents often results in reduced quality. If this was my problem, I'd adapt the existing RTF-generating code to generate DOCX using Apache POI instead.

Thanks Ulf Dittmer Yes, we are also concerned about the quality when we convert from RTF to DOCX. But considering the time factor, we are trying this option. If we find any utility that can give us close conversion, we are fine with adhering to that utility. We found that Apache POI does not read RTF. So if we are going to read xml and create DOCX direclty as we are doing today for RTF, then we are planning to use Apache POI.
