Railo/ColdSpring error when remoting in non-default web context

[Tom Bishop]

Hi,

I am getting a strange error with using cfajaxproxy with Model-Glue 3
on Railo 3.3.1.000 final which I believe is due to a misconfiguration
somewhere. However it has started after I moved the
application into a directory/context outside of the tomcat webapps/
root directory and main railo web context.

Prior to moving the app the AJAX call was working perfectly.

When I try to execute an ajax call to the remoteproxy it throws a 500
internal server error and I can see the following error coming back
in
firebug:

Sorry, a ColdSpring BeanFactory named sharedBeanFactory was not found
in application scope. Please make sure your bean factory is properly
loaded. Perhapse your main application is not running?

However, the sharedBeanFactory is set in the application scope
properly as I can dump the following without a problem:
#application.sharedbeanFactory.getbean("modelglue.modelGlueConfiguration")#

I can also cfdump the remote proxy generated by ColdSpring with no
problem.

A stack trace is here:

Sorry, a ColdSpring BeanFactory named sharedBeanFactory was not found
in application scope. Please make sure your bean factory is properly
loaded. Perhapse your main application is not running?

I am running Railo / Model-Glue 3/ ColdSpring with Apache webserver
and AJP proxy.

I have seen a few threads with this issue coming up (from a few years
ago) but was wondering if they have been resolved.

Any pointers would be greatly appreciated.

Tom

[Tom Bishop]

I would like to add that I have just tested my railo setup and it
appears that remoting is working OK - I created a test cfc with a
remote method which I can call without any problem.

This means that this must be a ColdSpring problem.

Any help would be great.

Many thanks,
Tom

[Tom Bishop]

Addendum:

Here is my remote proxy bean config:

<bean id="RemoteProductsService"
class="coldspring.aop.framework.RemoteFactoryBean" lazy-init="true">
<property name="target">
<ref bean="products" />
</property>
<property name="serviceName">
<value>RemoteProductsService</value>
</property>
<property name="relativePath">
<value>/myapp/model/services/proxy</value>
</property>
<property name="remoteMethodNames">
<value>*</value>
</property>
<property name="beanFactoryName">
<value>sharedBeanFactory</value>
</property>
</bean>

Also, there are no errors in my product.cfc.

[Tom Bishop]

I'm having lots of fun replying to my own post...

I changed the code in the remoteproxybean.cfc so that it just outputs
a cfcatch message (easier than having to comment out cftry/cfcatch
tags and I am now seeing the following error which, to be honest, I
have absolutely no idea what it is about:

Component [myapp.model.services.proxy.RemoteProductsService] has no
acessible Member with name [ADVICECHAINS]

Anyone know anything about this?

[Brian Kotek]

Can you actually see the generated proxy CFC and open it? Does anything in its code look odd?

Hi Brian,

Note: I changed the coldspring remoteproxybean.cfc to just output the
thrown error instead of catching it as the original error type.

I'm not sure if this is odd or not...

[Brian Kotek]

hmmm...well it looks right, you can see the use and checks for the adviceChains variable. So not sure what might be going on for it to think that it doesn't exist, but it seems like it must have something to do with that.

[Tom Bishop]

I removed the cfcatch from the remote proxy and it now reverts back to
the error:

The requested bean factory does not exist in the specified scope, if
you do not intend on handling this error, please use
namedFactoryExists(scope, name) to check for the factory first!

Maybe it is to do with the generated proxy not picking up the
sharedbeanFactory...

Hmmmmm!!!

[Tom Bishop]

I have tested the code in the main railo webapps/root context and it
works perfectly.

Something is happening with ColdSpring and the new web context that I
have set up that is causing ColdSpring to reference perhaps a
different context?

I'm fairly new to Railo and web contexts. Perhaps I haven't got the
new context set up properly.

[Brian Kotek]

Since it now sounds like a setup issue, you may have better luck asking on the Railo list.

[Tom Bishop]

I worked it out in the end and it was painfully simple:

I had to add a mapping to the proxy in the Railo administrator and
then call it via:

<cfajaxproxy cfc="myMapping.RemoteProductService"
jsclassname="RemoteProductService">

Doh!!!!

Thanks for your help and sorry for bothering you, Brian.
