                        className="nl.nn.adapterframework.jdbc.MessageStoreListener"

                        slotId="${instance.name}/ServiceName"
                        sessionKeys="key1,key2"
                />
                <!-- On error the message is moved to the errorStorage. And when moveToMessageLog="true" also to the messageLog (after manual resend the messageLog doesn't change). -->
                <errorStorage
                        className="nl.nn.adapterframework.jdbc.JdbcTransactionalStorage"

Method Detail

configure

public void configure()
               throws ConfigurationException

Description copied from interface: IListener

configure() is called once at startup of the framework in the configure() method of the owner of this listener. Purpose of this method is to reduce creating connections to databases etc. in the IPullingListener.getRawMessage(Map) method. As much as possible class-instantiating should take place in the configure() or open() method, to improve performance.

Specified by:

configure in interface IConfigurable

Specified by:

configure in interface IListener<M>

Overrides:

configure in class JdbcTableListener<M>

Throws:

ConfigurationException

getRawMessage

public M getRawMessage(Map<String,Object> threadContext)
                throws ListenerException

Description copied from interface: IPullingListener

Retrieves messages from queue or other channel, but does no processing on it. Multiple objects may try to call this method at the same time, from different threads. Implementations of this method should therefore be thread-safe, or synchronized.

Any thread-specific properties should be stored in and retrieved from the threadContext.

Specified by:

getRawMessage in interface IPullingListener<M>

Overrides:

getRawMessage in class JdbcListener<M>

Throws:

ListenerException

augmentMessageBrowser

protected IMessageBrowser<M> augmentMessageBrowser(IMessageBrowser<M> browser)

getMessageBrowser

public IMessageBrowser<M> getMessageBrowser(ProcessState state)

Description copied from interface: IProvidesMessageBrowsers

returns a browser of messages that are in ProcessState 'state', and are stored in a storage managed by the listener itself (as opposed to a storage configured as a messageLog or errorStorage in the configuration).

Specified by:

getMessageBrowser in interface IProvidesMessageBrowsers<M>

Overrides:

getMessageBrowser in class JdbcTableListener<M>

getSelectCondition

public String getSelectCondition()

setSlotId

public void setSlotId(String slotId)

Identifier for this service

setSessionKeys

public void setSessionKeys(String sessionKeys)

Comma separated list of sessionKey's to be read together with the message. Please note: corresponding MessageStoreSender must have the same value for this attribute

@Default(value="IBISSTORE")
 @Optional
public void setTableName(String string)

Description copied from class: JdbcTableListener

Name of the table to be used

Overrides:

setTableName in class JdbcTableListener<M>

setKeyField

@Default(value="MESSAGEKEY")
public void setKeyField(String fieldname)

Description copied from class: JdbcListener

Primary key field of the table, used to identify messages. For optimal performance, there should be an index on this field.

Overrides:

setKeyField in class JdbcListener<M>

setMessageField

@Default(value="MESSAGE")
public void setMessageField(String fieldname)

Description copied from class: JdbcListener

Field containing the message data

Overrides:

setBlobSmartGet

@Default(value="<code>true</code>")
public void setBlobSmartGet(boolean b)

Description copied from class: JdbcListener

Controls automatically whether blobdata is stored compressed and/or serialized in the database. N.B. When set true, then the BLOB will be converted into a string

Overrides:

setBlobSmartGet in class JdbcListener<M>

setStatusField

@Default(value="TYPE")
 @Optional
public void setStatusField(String fieldname)

Description copied from class: JdbcTableListener

Field containing the status of the message. For optimal performance, and index should exist that starts with this field, contains all fields that are used with a fixed value in the select condition, and end with the orderField.

Overrides:

setStatusField in class JdbcTableListener<M>

setTimestampField

@Default(value="MESSAGEDATE")
public void setTimestampField(String fieldname)

Description copied from class: JdbcTableListener

(optional) Field used to store the date and time of the last change of the statusField
