Java Migration from 1.4 to 1.6

[Anant Kamat]

Hi,
I am working on a Java Upgrade project from JDK 1.4 to JDK 1.6 Update 16(jdk1.6.0_16).
The project uses JAXB so I even changed the JAXB jars to latest version 2.2.
I made the changes in the build.xml pointing to 1.6 from 1.4
I am facing some problem with the JAXB jars.
I am getting "Cannot be resolved to a type" errors for few Java files in the code because of which the appropriate Jars are not being generated.

Please help me out as I am new to Migration stuff.

Thanks,
Anant

Be aware that Java 6 includes JAXB, whereas Java 1.4 did not. So the external JAXB version you have may be older or younger than what Java 6 has, and thus causing trouble.

The way to use a different version than the one that comes with the JRE is described in http://java.sun.com/javase/6/docs/technotes/guides/standards/

I just read the article but could not find any solution. Also the path mentioned in the page is not avaiable.
I am using JAXB version 2.2. I changed all the version numbers in the config files but to no use. The build still fails.
When I click on the build.xml failed path it shows me this
" <javac encoding="Cp1252" srcdir="src/java/com/sbc/sde" destdir="${sde.build.home}" debug="${compile.debug}" optimize="${compile.optimize}" source="1.6" target="1.6"> "

I changed the source and target from 1.4 to 1.6

This: srcdir="src/java/com/sbc/sde" is most certainly wrong. Most likely it should be srcdir="src/java"

Hi All,
My problem is resolved. Actually the problem was due to the XSD interpretation by JAXB 2.0
I had to make certain code changes.

Thanks for all your help.
