Global Resource Properties

Connection Settings

The connection settings of global resource can be managed from the adapter properties, from "Global Resource Settings" within the Control Panel.

JMS adapter type supports point-to-point communication type that sends to a single application (connection queue) and publish communication type that sends message to multiple applications (the topic connection).

Topic Connection Setting

Basic settings

Item name	Required / Optional	Use of Variables	Description	Remarks
Name	Required	Not available	Enter the name of the connection setting.
Type	Required	Not available	Select [Topic settings].

Required settings

Item name	Required / Optional	Use of Variables	Description	Remarks

JMS provider must support XA transactions. Refer "Transaction" for more information.
Initial context factory name	Required	Only environment variables are available.	Enter the factory implementation class to generate the initial context. The class name depends on the JMS provider's class libraries stored by $DATASPIDER_HOME/server/plugin/data_processing/modules/jms_adapter. Learn more information about setting the initial context factory from "Preferences" Learn more about class library from "Library Installation".
Provider URL	Required	Only environment variables are available.	Enter the provider URL provided by naming service . Setting depends on each provider. See "Preferences" for more information .
User name	Optional	Only environment variables are available.	Enter the user name to use the naming service.

Components Pool Settings

Component pool settings can only b set from "Global Resource Settings" from Control Panel.

Security

Security can only be set from "Global resource settings" from Control Panel.

Default

In order to correspond to a variety of JMS vendors,JMS uses JNDI (Java Naming and Directory Interface) naming service and JMS has realized the connection to the provider.

Therefore, JMS does not not unique to each provider to develop a MS adapter, data resource configuration properties naming service URL, and the name QueueConnectionFactory initial binding (setting the Name [Initial context factory name] part) to Simply changing, and we each can be connected JMS provider.

The setting of [Initial context factory name], [Provider URL] depend on the JMS provider, therefore, contact JMS vendor company.

Specification Limits

None.

Main exceptions

Exception Name	Causes	Solution
InvalidPropertyConfigurationException Are not given the resources required fields. : <Property name>	[<property name>] is not specified.	[<property name>] Please specify.
javax.naming.NoInitialContextException: Cannot instantiate class:	[Initial context factory name] is wrong, or class library has not been copied.	Check [Initial context factory name].Or check if the class library has been copied.
javax.naming.ConfigurationException: No scheme found in URI.	[Provider URL] is incorrect.	Confirm [Provider URL].
javax.naming.NameNotFoundException	[Topic factory] or [Queue factory] is incorrect.	Confirm [Topic factory] or [Queue factory].
javax.naming.NameNotFoundException	[Topic name] or [Queue name] is incorrect.	Confirm [Topic name] or [Queue name] .
javax.naming.NamingException: unable to connect, exception = javax.jms.JMSException: error creating socket connection to localhost:4001, message: Connection refused	JMS provider is not running, or the connection settings are incorrect.	Check whether JMS provider is running, or check the contents of connections setting.

Notes

DataSpider does not directly refer to the vendor class, because vendor class is dynamically loaded into the JVM when running, there is a need to store vender class library to $DATASPIDER_HOME/server/plugin/data_processing/modules/jms_adapter.
Learn more from "Library Installation".

Because of the setting of "factory" and "queue name" ,JMS provider may not answer due to the incorrect object name.
About this, please contact us or see the vendors document.
Setting of [User name], [Password] is the user name and password that is also the secure when accessing to JNDI store.If necessary, describe the password if it has been set.
