Now I want to mograte to Apache 3.9 latest and stable version. I have added JAR file poi. WorkbookFactory method not found. The POI-3.9 jar, the POI-OOXML-3. Download poi-ooxml-3.9.jar. Poi/poi-ooxml-3.9.jar.zip( 873 k) The download jar file contains the following class files or Java source files.

Apache have released version 3.5 of, the Java library for working with Microsoft's document formats. POI previously supported Microsoft's OLE2 compound document formats as used in Office 97-2003 (versions 8.0 - 11).

With POI 3.5 Apache have added support for Microsoft's Office Open XML (OOXML) document standard, the default file format for Microsoft Office 2007. Existing code using the HSSF user model will continue to work correctly with POI 3.5 although it cannot support the OOXML format. To work with both OOXML and OLE2 formats POI has a new SS user model ( org.apache.poi.ss.usermodel) which provides a common API. The new SS model is heavily based on the old HSSF model ( org.apache.poi.hssf.usermodel) and as such retains a familiar feel for developers used to working with HSSF. Updating from one to the other is also not a particularly arduous task, the main difference being that the package name and class names have been tweaked to remove HSSF from them. It should be noted however that there are some features that are not yet covered by the SS user model. Apache's Yegor Kozlov, release manager for POI 3.5, told us: Currently the SS usermodel covers about 90% of the functionality provided by HSSF.

The goal is to achieve full coverage. In particular, conditional formatting and data validation are not yet supported by XSSF. There is also some work to do with graphics and rich text (both in HSSF and XSSF).

POI's OOXML support was developed from scratch and is independent of the OpenXML SDK. Along with Julien Chable's which, a significant contribution to the OOXML implementation in version 3.5 came from, an Open Source company which was commissioned by Microsoft to do the work. Microsoft's Robert Duffner told us that Microsoft themselves provide the funding, architectural guidance, program & project management, feature prioritisation & release strategy for the OOXML work with Sourcesense as the development partner. Microsoft's involvement inevitably caused some controversy, with some POI contributors questioning the validity of Microsoft's Open Specification Promise (OSP) patent license. Writing on his blog at the time project founder Andrew Oliver stated: Although the OSP does not address some of the edge cases where work may be required for compatibility but not for implementing the specification, Microsoft has agreed to go further and sign a specific agreement with Apache which will address this concern for the work they have funded with POI.

Furthermore, the OSP will be managed as a legal product much like the way that an Open Source project is, with revisions as they are needed. When we spoke to Oliver however he did make it clear that he still harbours some concerns about potential patent issues in the specification: The patent promise only goes to the extent of conformance to the OOXML specification, it does not go as far as compatibility with the products using the specification. Microsoft has key patents on things that could fall outside of this (i.e. Methods of reading an OOXML document that does not conform to its schema) that are not in the scope of conformance to the specification but are in the scope of POI's mission of compatibility with popular proprietary office software. To be clear, Microsoft employees Robert Duffner and former employee Sam Ramji were very willing to work on this issue, but currently there is not sufficient focus on resolving these and other IP issues within the POI developer community itself.

There is a belief in trusting that Microsoft means well and that its interests will prevent it from doing something wrong. Crash Bandicoot 2 Ps3 Cheats. I disagree and think that corporate strategies/interest change. POI also needs more IP auditing and governance overall, I think the project has been doing a bad job of this lately.

Additionally, no efforts were made to ensure that any other inadvertently or purposefully implemented patents held by Microsoft which are not required for conformance to the OOXML specifications and were done by Sourcesense on Microsoft's dime were covered (outside of this 'promise'). Sourcesense signed a CLA with Apache, but there is no similar agreement between Apache and Microsoft. This means that Sourcesense would be theoretically liable to Apache should there be a problem, but I do not know that is sufficient. I would like to see the developer community take an active role in resolving all of these issues.
