Thanks for point that out... Now, it does pick up the persistence
unit...
However, I am still not able to start up pre-bundled with Eclipse GWT
Jetty server.
First, it complained that I didn't specify a persistence provider. I
did that by changing my entityManagerFactory to this:
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="testUnit">
<property name="jpaDialect"
value="org.springframework.orm.jpa.vendor.TopLinkJpaDialect" />
<property name="jpaVendorAdapter"
value="org.springframework.orm.jpa.vendor.TopLinkJpaVendorAdapter" />
</bean>
After I did this, it started complaining that I "Cannot apply class
transformer without LoadTimeWeaver specified".
Well, I tried specifying the load time weaver:
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="loadTimeWeaver">
<bean
class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"
/
>
</property>
<property name="persistenceUnitName" value="testUnit">
<property name="jpaDialect"
value="org.springframework.orm.jpa.vendor.TopLinkJpaDialect" />
<property name="jpaVendorAdapter"
value="org.springframework.orm.jpa.vendor.TopLinkJpaVendorAdapter" />
</bean>
When I specify that, it complains that in order to use that particular
weaver, I need to start with a Java agent... From Spring
documentation, that would be spring-agent-2.5.5.jar...
I opened "Run Configurations" in Eclipse and chose my GWT web app run
configuration. Then, I switched to the Arguments tab and put this in
VM arguments:
"-javaagent:c:\spring-agent-2.5.5.jar"
This is the exact same configuration (in my spring config and in my
run configuration) that I use to run JPA DAO tests without requiring a
server and it runs just fine within Eclipse and within maven...
However, even after specifying the Java agent the way I just
described, I still get the same error... It's as if GWT Hosted mode
server doesn't see that I am asking it to start with a specific Java
agent (specified in the Arguments-vm arguments in Eclipse)...
Any ideas as to how to get this to work?
Thanks,
Yaakov.
