Build with Java 1.4.2
I'm using eclipse for my IDE and my project has a build.xml. Whenever I
do a
build, I right-click the build.xml and select Run Ant... I then select
the
All target. Works great.
Recently, my cohorts have suggested I need to switch from the 1.3.1 Java
to the 1.4.2
Java to be compatible with a new run environment. I start eclipse with
C:\eclipse\V2_1_3\eclipse\eclipse.exe eclipse -vm
C:\Java\j2sdk1.4.2_07\bin\javaw.exe
So it uses the newer java vm. However I'm getting this when I do my
build:
[echo] The classpath for compilation is
c:\Java\j2sdkee1.4.2_07\lib\j2ee.jar:jars/xerces.jar:jars/MCP.jar
[echo] Java home is C:\Java\j2sdk1.4.2_07
[javac] Compiling 307 source files to C:\SPEC\classes
[javac] C:\SPEC\src\com\sun\jini\debug\Debug.java:177: cannot
access java.lang.Object
[javac] bad class file:
C:\Java\j2sdk1.4.2_07\jre\lib\rt.jar(java/lang/Object.class)
[javac] class file has wrong version 48.0, should be 47.0
[javac] Please remove or make sure it appears in the correct
subdirectory of the classpath.
[javac] private String propertyName;
[javac] ^
[javac] 1 error
[javac] BUILD FAILED: file:C:/SPEC/build.xml:110: Compile failed;
see the compiler error output for details.
Total time: 3 seconds
Any ideas what is going wrong and how to fix it?
Here is my build.xml:

<!-- SPECjAppServer build definitions.
August 2002 : Modified default to use CMP
April 2002 : Modified for SPECjAppServer 2001
April 2001 : Minor Modifications by Tom Daly (Sun)
March 2001 : Thanks to Bill Kayser (Alliare) for creating the initial
version of this
ant input file and for the documentation accompanying it
which has been
incorporated into the README.html
Please refer to the readme.html for instructions on building and
deploying
the SPECjAppServer source.
This file contains targets for compiling and packaging war files and
ejb files using ant 1.3 or later.
You can find the ant binaries at http://jakarta.apache.org/ant
It should not be necessary to edit this file.
EXECUTING TARGETS
To execute a target for a particular appserver such as the reference
implementation, do this:
ant -Dappserver=ri.1.3.1 target
Substitute "ri.1.3.1" for the name of the appserver, such as "tomcat"
or
"jrun".
"ant" should be invoked from the SPECjAppServer top directory
($JAS_HOME)
SUPPORTED TARGETS
These are the targets you are most likely to use:
clean: Delete all output files
jAppServer-ear: Builds all ejb jar files and warfiles needed for
SPECjAppServer, minus the supplier, emulator and
driver.
emulator-ear: Builds the emulator ear file with the war inside.
allejbs: Builds just the ejb jar files for all
deployable ejbs
clean-driver: Removes the driver class files and jar in
preparation for
rebuilding.
driver: Builds the driver.jar file, this must be
called explicitly
as it is not part of the default build also
driver.jar is not
removed by the "clean" target
load: builds the load.jar file
loaddb: Executes the load program for all domains.
load-corp,load-supp,load-mfg,load-ords,load-rules:

<!-- DRIVER clean and REBUILD Targets
It is not expected that the driver will need to be deleted or
rebuilt
but the next 2 targets provide for this should the user
explicitly want
to do it. So be aware that the "clean" target will not effect
the
driver classes or jar, you must use "ant clean-driver" to
remove driver files
and then "ant driver" to build the new driver
The driver target also rebuilds the launcher.jar file which
contains the
logic to initiate the driver in a portable fashion.

Re: Build with Java 1.4.2
Posted by Antoine Levy-Lambert <an...@gmx.de>.
Note that you are using target=1.2 in your build.xml for the javac task.
Not sure if it plays a role in your problem.
I do not know what are exactly class file major versions 47 and 48.
I found only this doc about this type of issue :
http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#80961
Cheers,
Antoine
