Hi,
I am getting the error below for the following Guice binding:
protected void configure() {
.....
bind(MemcacheService.class).toInstance(getMemcacheServiceInstance()); //
Line 44
.....
}
protected MemcacheService getMemcacheServiceInstance() {
return MemcacheServiceFactory.getMemcacheService();
}
Can someone please help me in identifying what I am doing wrong here?
I am using the Low Level API for caching and I did not specify any
configuration in any XML file. I am in dire need of help :(. Please
help me.
Thank you,
Imran
