i'm using Hibernate 2.1 beta 3
I see a java.lang.AbstractMethodError: net/sf/hibernate/persister/AbstractEntityPersister.... at startup!
in fact :
Code:
java.lang.AbstractMethodError: net/sf/hibernate/persister/AbstractEntityPersister.getTableName

Exception in thread "P=802434:O=0:CT"
the cause is that at runtime the class is an inner class that don't implement getTableName() from Joinable interface.
i know that's in FAQ but the solution in not really clear.
And i'm working with Websphere Studio Application Dev with the jdk of IBM (1.3 for websphere4) and not IntellJ or JBoss
when looking at the option of the jvm :
Code:
Usage: javaw [-options] class [args...]
(to execute a class)
or javaw -jar [-options] jarfile [args...]
(to execute a jar file)
where options include:
-cp -classpath <directories and zip/jar files separated by ;>
set search path for application classes and resources
-D<name>=<value>
set a system property
-verbose[:class|gc|jni]
enable verbose output
-version print product version
-showversion print product version and continue
-? -help print this help message
-X print help on non-standard options
the extended options are :
Code:
-Xbootclasspath:<directories and zip/jar files separated by ;>
set search path for bootstrap classes and resources
-Xbootclasspath/a:<directories and zip/jar files separated by ;>
append to end of bootstrap class path
-Xbootclasspath/p:<directories and zip/jar files separated by ;>
prepend in front of bootstrap class path
-Xcheck:jni perform additional checks for JNI functions
-Xcheck:nabounds perform additional checks for JNI array operations
-Xdebug enable remote debugging
-Xfuture enable strictest checks, anticipating future default
-Xgcpolicy[:optthruput]|[:optavgpause]
control garbage collector behavior
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xnoagent disable support for oldjdb debugger
-Xnoclassgc disable class garbage collection
-Xoss<size> set maximum Java stack size for any thread
-Xquickstart used for improving startup time of some Java applications
-Xrs reduce the use of OS signals
-Xrunhprof[:help]|[:<option>=<value>, ...]
perform heap, cpu, or monitor profiling
-Xrunjdwp[:help]|[:<option>=<value>, ...]
load debugging libraries to support remote debug applications
-Xss<size> set maximum native stack size for any thread
The -X options are non-standard and subject to change without notice
note :
disabling outer join seems to solve my problem but...
<property name="use_outer_join">false</property>
but i'd like to have this option enabled
any idea ?
thx a lot
