Hi, I've been using sisu-guice 3.0-SNAPSHOT (https://
repository.sonatype.org/content/groups/forge/org/sonatype/sisu/sisu-
guice/3.0-SNAPSHOT/) with my GWT app with GWTP, hibernate and tomcat
6.0 for about a month now. All was working well, and was quite easy to
setup. While browsing the sonatype.org's repository, I found that
another version of guice 3.0-SNAPSHOT is available (https://
repository.sonatype.org/content/groups/forge/com/google/inject/guice/
3.0-SNAPSHOT/) and decided to make the switch over, just because of
the better name format.
Anyway, long story short, I now can not start my server and get an
error that states that a null value was returned by binding at
JpaPersistModule.java:63 because of a parameter of 1 in
JpaPersistService.<init>() is not @Nullable while locating Properties
annotated with @com.google.inject.persist.jpa.Jpa().
I'm not sure what changed from these two versions...
My persistence.xml file looks like this:
<persistence-unit name="myUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
.... stuff here for entities & db setting and
cache ....
</persistence-unit>
My web.xml file defines a guiceFilter for the servlet:
<filter>
<filter-name>guiceFilter</filter-name>
<filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>guiceFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
My DispatchServletModule.java which extends ServletModule looks like
this:
public class DispatchServletModule extends ServletModule {
@Override
public void configureServlets() {
install(new JpaPersistModule("myUnit"));
filter("/*").through(PersistFilter.class);
bindConstant().annotatedWith(SecurityCookie.class).to("JSESSIONID");
filter("*").through(HttpSessionSecurityCookieFilter.class);
serve("/" + ActionImpl.DEFAULT_SERVICE_NAME +
"*").with(DispatchServiceImpl.class);
}
}
Some of these settings are defined for GWTP. I've been scratching my
brain to figure where this error is coming from and can make any
headway and advice are most welcomed.
Thank you. Jay
