Summary: Error compiling EJB-QL with JDK 1.3.1
Initial Comment:
OS: Windows XP
JDK: SUN 1.3.1
JBOSS: 3.2.3
Hi,
the class JDBCEJBQLCompiler uses the method "public
StringBuffer append(StringBuffer sb)" from the
StringBuffer Class which is not available in JDK prior to
version 1.4.
It's quite easy to reproduce as even simple SELECT
queries leads to the following deployment exception:
java.lang.NoSuchMethodError
at
org.jboss.ejb.plugins.cmp.jdbc.JDBCEJBQLCompiler.visit
(JDBCEJBQLCompiler.java:932)
at
org.jboss.ejb.plugins.cmp.ejbql.ASTSelect.jjtAccept
(ASTSelect.java:25)
at
org.jboss.ejb.plugins.cmp.jdbc.JDBCEJBQLCompiler.visit
(JDBCEJBQLCompiler.java:487)
...
Bye,
Raphael

Thanks for your answer.
Your right that it's not a bug in the source code. I rather
mean a "bug in the binary distribution".
The download page at jboss.org is imho misleading as it
states that version 3.2 runs on jdk 1.3. My understanding of
that statement is that the compiled download version runs on
JDK 1.3.
The J2EE Spec 1.3 requires JDK 1.3 as runtime environment,
so it's not quite obvious why JBoss 3.2 dist is compiled with
1.4.
It *can* be very time consuming to build such a complex
system like JBoss. So I think that most people who download
JBoss just start with the compiled version and will possibly run
into that problem...

It is definitely not a bug in JBoss. StringBuffer in 1.3.1
still has append(Object obj). The problem is that you are
running Java code compiled with 1.4 compiler in 1.3.1
machine. If you recompile JBoss with 1.3.1 the problem will
go away.
I believe, there were performance reasons (avoid toString())
to add append(StringBuffer sb) while already having
append(Object o). I am not going to fix it right now unless
someone convinces me that I should.
In general, I think, it is a good practice to compile the
application with the compiler compliant with the target machine.
