Urgent! How OFBiz supports multi databases;

Hi All!
First, I add a delegator and a datasource in entity-engine.xml:

<delegator name="hello3" entity-model-reader="main"
entity-group-reader="main" entity-eca-reader="main"
distributed-cache-clear-enabled="false">
<group-map group-name="com.aicent"
datasource-name="hello3"/>
</delegator>

<datasource name="hello3"
helper-class="org.ofbiz.entity.datasource.GenericHelperDAO"
field-type-name="mysql"
check-on-start="true"
add-missing-on-start="true"
check-pks-on-start="false"
use-foreign-keys="true"
join-style="ansi-no-parenthesis"
alias-view-columns="false"
drop-fk-use-foreign-key-keyword="true"
table-type="InnoDB"
character-set="latin1"
collate="latin1_general_cs">
<read-data reader-name="seed"/>
<read-data reader-name="demo"/>
<read-data reader-name="ext"/>
<inline-jdbc
jdbc-driver="com.mysql.jdbc.Driver"
jdbc-uri="jdbc:mysql://127.0.0.1/hello"
jdbc-username="root"
jdbc-password="asdfgh"
isolation-level="ReadCommitted"
pool-minsize="2"
pool-maxsize="20"/>

</datasource>

Then,in my demo hello3's file entitygroup.xml:
<entity-group group="com.aicent" entity="HelloPerson" />
<entity-group group="com.aicent" entity="HelloHobby" />
<entity-group group="com.aicent" entity="HelloPersonHobby" />

These entities HelloPerson HelloHobby HelloPersonHobby are defined in
entitymodel.xml

In services.xml I define a service named createHelloPerson:

<service name="createHelloPerson" engine="java"
location="org.ofbiz.hello3.Hello3Services"
invoke="createHelloPerson">
<description>Create a HelloPerson</description>
<auto-attributes mode="IN" entity-name="HelloPerson"
include="nonpk" optional="true" />
<attribute name="helloPersonId" mode="OUT" type="String"
optional="false" />
</service>

All other files were well created.

Then I am starting OFBiz, A error encountered in console.log

Thank you for your response!
But,maybe you didn't catch what I meant
I knew it could not find definition for entity name hello3.HelloPerson.
Actually it could not find definition for entity name HelloPerson either.
So I'am anxious to know how OFBiz supports multi databases.

Thank you!
You mean I modify all the seven files in my ofbiz according to the link you give?
And How I set the attribute default-group-name in delegator hello3 and default?
Is it right below?

<delegator name="default" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main" distributed-cache-clear-enabled="false" >
<group-map group-name="org.ofbiz" datasource-name="localmysql"/>
</delegator>

<delegator name="hello3" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main" distributed-cache-clear-enabled="false" default-group-name="com.aicent">
<group-map group-name="com.aicent" datasource-name="hello3"/>
</delegator>

the simple answer is yes.
However I don't think what you have in mind is covered under that answer.
your problem of finding an entity has nothing to do with a database.
Think of the database only as a storage medium.
the error your getting is from the entity engine.
it would be wise to re-visit the tutorial and the links on the videos.

http://docs.ofbiz.org/display/OFBIZ/OFBiz+Beginner%27s+Development+Guide+Using+Practice+Application
This will save you having to ask basic questions on the Mailing list and
speed up you developement.

RE: Urgent! How OFBiz supports multi databases;

In reply to this post by BJ Freeman

Thank you!
OFBiz can't find entity HelloPerson, so I try hello3.HelloPerson.
But it fails too.

There is no problem in the entity engine, I think.
In my entity-engine.xml file, I set up two delegators:default and hello3. Default uses datasource localmysql and hello3 uses datasource hello3.

I start Ofbiz. When it parses file services.xml, it can't tell which delegator entity HelloPerson belongs to and prints error info.

Did I make myself clear?

the simple answer is yes.
However I don't think what you have in mind is covered under that answer.
your problem of finding an entity has nothing to do with a database.
Think of the database only as a storage medium.
the error your getting is from the entity engine.
it would be wise to re-visit the tutorial and the links on the videos.

http://docs.ofbiz.org/display/OFBIZ/OFBiz+Beginner%27s+Development+Guide+Using+Practice+Application
This will save you having to ask basic questions on the Mailing list and
speed up you developement.

It's not totally clear what you're trying to do, just what you've
done. I'll guess here, but in general it's best to describe:

1. what you did
2. what you expected to happen
3. what actually happened

... and perhaps also your thoughts on the differences between #2 and #3.

I'm guessing you want different tables in different databases. In that
case, just use one delegator and not two, and have two groups in the
delegator with the different group-names pointing to different
datasources.

Thank you for your instructions!

Yes, I want different tables in different databases.
But I don't care one or two delegators.

RE: Urgent! How OFBiz supports multi databases;

Just now I tried according to you suggestion.
I use default delegator and have two groups in the delegator with the different group-names pointing to different data sources.
It works!

I had thought I should have set up two delegators supporting two or more databases;

Thank you very much, you help me a lot!
