Hi,
I've been experimenting with a Media Filter for text extraction from PowerPoint
files. It's based on the Apache POI libraries, as was suggested by others in a
previous thread.
It uses the poi, poi-scratchpad, and poi-ooxml artifacts, in version 3.6, the
latest release version from Apache. I haven't done much with Maven, and am not
sure how to tell it which libraries I need.
This bit was already in the dspace-api/pom.xml file:
<dependency>
- <groupId>poi</groupId>
- <artifactId>poi</artifactId>
- </dependency>
I removed it, because I wanted the latest version of the libraries. Then, I
added these dependencies to the bottom of the file:
+ <dependency>
+ <groupId>org.apache.poi</groupId>
+ <artifactId>poi</artifactId>
+ <version>3.6</version>
+ </dependency>
+ <dependency>
+ <groupId>org.apache.poi</groupId>
+ <artifactId>poi-scratchpad</artifactId>
+ <version>3.6</version>
+ </dependency>
+ <dependency>
+ <groupId>org.apache.poi</groupId>
+ <artifactId>poi-ooxml</artifactId>
+ <version>3.6</version>
+ </dependency>
Somehow Maven magically found the correct versions of the dependencies, and
everything built fine. When I deployed DSpace and looked in the lib directory,
there were two versions of the main poi library there:
poi-2.5.1-final-20040804.jar
poi-3.6.jar
poi-ooxml-3.6.jar
poi-ooxml-schemas-3.6.jar
poi-scratchpad-3.6.jar
I couldn't figure out why the poi-2.5.1 version was still there, or find
anything that actually used it. So, in the interest of doing some quick
testing, I just deleted it.
Can someone give a hand on how to do this properly? I'm trying to tell the
build process to find and use only version 3.6 of poi.
Thank you!
