I had to make some changes to get ozone0.4.5 working with jdk1.1.8.
The first thing was very strange:
in Makefile.env the .jar's and class-directories from ozone are added to the
CLASSPATH.
All Makefiles read Makefile.env, thus while making "make" all
jars get added to the CLASSPATH several times. There seems to be
a limit on the length of environment variables (at least on FreeBSD).
And javac finally couldn't find the .java files:
gmake -C test
gmake[3]: Entering directory
`/home/guest/guettli/ozone/org/ozoneDB/DxLib/test'
javac -g AbstractTest.java CollectionTest.java DiskHashTest.java
MapTest.java SetTest.java Test.java
error: Can't read: AbstractTest.java
I changed Makefile.env to:
ifndef OZONE_HOME
print_error:
@echo "Set the OZONE_HOME variable first!"
else
ifndef OZONE_JARS_SET
OZONE_JARS_SET=true
export OZONE_JARS_SET
OZONE_JARS = $(subst r /,r:/,$(wildcard $(OZONE_HOME)/bin/*.jar))
export CLASSPATH:=$(OZONE_HOME):$(OZONE_JARS):$(CLASSPATH)
endif
endif
and I changed $(JAVAC) to javac. ( in ozone/INSTALL you say the default is
javac)
if you prefer the diff: (diff -u)

the second change:
my javac said:
javac -g AbstractTest.java CollectionTest.java DiskHashTest.java
MapTest.java SetTest.java Test.java
SetTest.java:29: Reference to equals is ambiguous. It is defined in
boolean equals(java.lang.Object)
and boolean equals(java.lang.Object).
if (!set.equals (set2) && set.count()>0)
equals is defined in java.lang.Object (all objects inherit from it)
org.ozone.DxLib.DxCompatible
I commented equals() int DxCompatible. And it compiled without error. (The
same problem
could be with clone())
third change:
I took the old ClassManager.java because I am using jdk1.1.8 ,
but some other Objects need the new flushCache(),
I glanced at the could and added an empty function (is this save?)
public void flushCache() throws Exception {
}
fourth change:
the openxml.jar was not included. I took the one from 0.4.4
while compiling opp produced the following warnings
very often (unable to open ...):
javac -g util/BLOBContainer.java util/BLOBContainerImpl.java
util/BLOBInputStream.java util/BLOBOutputStream.java util/BLOBPage.java
util/BLOBPageImpl.java
cd util; opp org.ozoneDB.util.BLOBContainerImpl

update methods:
(processing BLOBContainer.java...)
BLOBContainerImpl.ocd:0: warning: Unable to open descriptor file.
init ("int")
write ("int|[B|int|int")

I had no time to see what was wrong with this.
