hello

 

In my pc i have installed the 1.6_10 jdk.

i must to compile, for generate one war for one 5.0 tomcat that runs into
one 1.4 jdk, my classes.

for this pourpose i make this into one build.xml file:

<javac destdir="${entornoBase}/${classes}"
includes="**/${path}/${filej}.*,**/${filej}.*"
excludes="**/*EJB/*.*,**/**ejb/**/*.*" classpath="${classpath}"
optimize="on" deprecation="on" source="1.4" target="1.6">

                  <src path="${entornoBase}/${fuentes}"/>

</javac>

 

but using the options: 

optimize="on" deprecation="on" source="1.4" target="1.6">

 always appears into my tomcat this:

2008-12-26 17:42:07,483
[ContainerBackgroundProcessor[StandardEngine[Catalina]]] ERROR

can you help me for compiling the classes for make it compatible with the
1.4 jdk?

 

thanks
