Jeroen,
Your last message was empty, but I assume you were telling me that the
source snapshot is complete and contains the same binaries as the binary
snapshot. I must have been running an old version of a converted library
because everything works okay with the rebuilt source snapshot. I'm sorry
about reporting an non-existent problem.
If you were replying to my other questions, please resend it.
Here are some other issues:
Issue #1. Are you planning on adding support for new jdk1.4 methods to the
map.xml file as they are added to classpath?
I tried to convert an oracle jdbc jar built for jdk1.4 and got a
NoSuchMethod exception on StringBuffer.append (StringBuffer)
It's probably missing from the map.xml but in the classpath.dll
ikvmc ojdbc14.jar -target:library -out:ojdbc14.dll -reference:classpath.dll
-reference:ik.vm.net.dll
Parsing class files
Constructing compiler
Loading remapped types (1)
Compiling class files (1)
Loading remapped types (2)
Compiling class files (2)
java.lang.NoSuchMethodError:
java.lang.StringBuffer.append(Ljava.lang.StringBuff
er;)Ljava.lang.StringBuffer;
at oracle.jdbc.driver.OracleSql.handleODBC()V
java.lang.NoSuchMethodError:
java.lang.StringBuffer.append(Ljava.lang.StringBuff
er;)Ljava.lang.StringBuffer;
at oracle.jdbc.driver.OracleSql.handleODBC()V
Issue #2. Here's another problem I encountered that isn't serious but you
might want to look into the cause since these might be bugs in IKVM related
to support for loading serialized class resources.
When I debug my app and break on all clr exceptions as they are thrown, I
see issues when I try to deserialize class resources from the converted
Oracle lib.
I downloaded classes12.zip from Oracle, this is their jdbc driver built for
jdk1.2 or jdk1.3.
I converted it with:
ikvmc classes12.jar -target:library -out:classes12.dll
-reference:classpath.dll -reference:ik.vm.net.dll
When I run the following code which is valid, I get several exceptions
thrown that get caught related to missing the .security resource in the
classpath assembly, a NoSuchField exception, and a InvalidClassException.
oracle.sql.CharacterSet theCharacterSet = oracle.sql.CharacterSet.make (-1);
Here are the exceptions thrown that get caught and their stack traces:
