[jboss-user] [JBoss Cache: Core Edition] - attach()detach() can transaction, but find() can not?
I'm sorry ask the same here,- -, no answer in the pojo-edition:)
hi all,
when i use as the below ,i can rollback the cache:
| clientDao.insertClient(client);
| Client clientCache = clientDao
| .getClientByName(client.getName());
| //cacheManager.insertClientToCache use pojocache.attach(id,client)
| cacheManager.insertClientToCache(clientCache);
| throw new RuntimeException();
|
or
| clientDao.deleteClientByTid(tid);
| //cacheManager.deleteClientByTid use pojocache.detach(id)
| cacheManager.deleteClientByTid(tid);
| throw new RuntimeException();
|
they work fine, but when i use pojocache.find(...) to get a pojo,then i modified the name
field, it can't rollback,
| clientDao.updateClient(client);
| Client cInCache = cacheManager
| .getClientFromCacheByTid(client.getTid());
| cInCache.setName(client.getName());
| throw new RuntimeException();
|
when the up is done,clientDao.updateClient rollbacked,but the client in cache ,it's
Name field not rollback,
i've placed jboss-aop.jar to my web/WEB-INF/lib,and copyed one pojocache-aop.xml(from
jbosscache-pojo.jar/METE-INF/) to web/WEB-INF/classes,
i've read the userguide doc,
from the Chapter6.Instrumentation , i don't know how i do the below in a web
application server, e.g.; tomcat
|
| The jboss.aop.path system property set to the location of pojocache-aop.xml
|
| A javaagent argument which includes jboss-aop-jdk50.jar
|
| These requirements lead to the following example ant task:
|
|
| <java classname="Foo" fork="yes">
| <jvmarg value="-javaagent:lib/jboss-aop.jar"/>
| <jvmarg value="-Djboss.aop.path=etc/META-INF/pojocache-aop.xml"/>
| <classpath refid="test.classpath"/>
| </java>
|
| There is also a pojo-run command line script in the POJO Cache distribution that
passes the proper a
| rguments to the JVM for you.
|
|
| $ pojo-run -classpath myclasses org.foo.Bar
|
| Once the JVM is executed in this manner, any class with the @Replicable annotation
will be instrumen
| ted when it is loaded.
|
then in 5.3 AOP Configuration
| POJO Cache supplies a pojocache-aop.xml that is required to be set via a system
property: jboss.aop.
| path during compile- or load-time, or
| placed in the user's classpath
| . The file now consists of the interceptor stack specification, as well as annotations
for POJO inst
| rumentation. It is listed fully in the Appendix section. Note that the file should not
normally need
| to be modified. Only an advanced use-case would require changes.
|
so, in web server ,if i placed jbosscache-aop.jar(and other requied jar) to WEB-INF/lib
and pojocache-aop.xml to WEB-INF/classes, then pojocache can work fine?
i've done this,but ,use find() to get a object from cache,i can't rollback the
field,
Have i forgot something important?
how can i now to do?Any advice would great appreciate
