I think I'm still missing a piece of the puzzle though since my modified
.java program is NOT making it into the dspace-api-1.5.1.jar file in
/dspace/lib.
I have added the new sub-directory custom-api and file pom.xml file
under {dspace-source}/dspace/modules.
I added the following to {dspace-source}/dspace/modules/pom.xml:
<module>custom-api</module> (I also commented out the xmlui, lni, oai,
and sword modules in this pom.xml file (for the time being until we are
using them, as per your suggestion)).
I added the following to {dspace-source}/dspace/pom.xml:
<profile>
<id>custom-api</id>
<activation>
<file>
<exists>../custom-api/pom.xml</exists>
</file>
</activation>
<modules>
<module>../custom-api</module>
</modules>
</profile>
I think the trick is WHERE to put my custom .java program so that it
will be picked up and put in the right place in the application once
it's compiled.
Take this example:
Let's say I make a modification to:
dspace-1.5.1-src-release/dspace-api/src/main/java/org/dspace/app/mediafi
lter/PDFFilter.java
Do I put it in:
Dspace-1.5.1-src-release/dspace/modules/src/main/java/org/dspace/app/med
iafilter/PDFFilter.java ????
And is the package in my new PDFFilter.java still package
org.dspace.app.mediafilter;
I'm thinking maybe not since I just saw this in the pom.xml file you
attached to your email last night:
<groupId>org.dspace.modules</groupId>
Do I need to create a {dspace-source}/custom-api directory??
Please forgive me - this is the first time I have worked with pom.xml
files!
Thanks!
Sue

Or to be more explicit you add the pom at
{dspace-source}/dspace/modules/custom-api/pom.xml
and modify the following with <module>custom-api</module>
{dspace-source}/dspace/modules/pom.xml
And add custom-api as a dependency in
{dspace-source}/dspace/pom.xml

Susan,
The way to do it without altering the code in place requires creating a
custom maven project within the dspace/modules/ directory, wiring it
into the dspace/pom.xml and dspace/modules/pom.xml so that it compiles
into the build process.
At this point, I'm seeing community member using both approaches, and
I'm unsure which I would most recommend. But here's what I try to
approach as a best practice.
1.) I don't like to alter code in place in dspace-api, dspace-xmlui or
any of those projects unless I intend to contribute it into the next
release of DSpace 1.5.x
2.) Keeping all those projects around lengthens the build process and if
your not using all of them (dspace-sword, lni, etc) thats a lot of
compile time for nothing.
3.) Once configured properly, your changes in dspace/modules/xxx will
always be separate from the rest of the codebase, but you will still
need to verify that upgrades don't break your customizations by
comparing your code to the original. Something we continue to strive to
get away from.
So I would recommend the following steps:
a.) create a dspace/modules/custom-api/pom.xml for your api changes.
That looks something like the attached pom.xml
