Re: [gt-user] How can I remove the persistence resource.

[Martin Feller]

The remove() method of a resource is called by ResourceHome if the resource
is removed, if the resource implements the interface RemoveCallback.
(see 
http://www.mcs.anl.gov/~gawor/javawscore/HEAD/doc/javadocs/org/globus/wsrf/RemoveCallback.html)

But there is no magic that deletes persistence data of a resource automatically.
You have to implement in remove() whatever resource-specific you want to happen
in case a resource is removed, including handling of persistence data.

Hi,

I am writing a web service with WS-CORE. I found under the directory

/home/globus/.globus/persisted/129.127.XX.XXX-8010/PersistentRgbWSDFAtt, there are lots of .ser file. I have a remove() method in class org.globus.wsrf.samples.rgbwsdfatt.PersistentRgbWSDFAtt (Same as the following one in red). I thought this method could help me remove the reference, but seems not. The following is the deploy-jnid-config.xml file of my RgbWSDFAtt service.

<?xml version="1.0" encoding="UTF-8"?>
<jndiConfig xmlns="http://wsrf.globus.org/jndi/config";>
    <service name="RgbWSDFAttService">
        <resource
            name="home"
            type="org.globus.wsrf.samples.rgbwsdfatt.RgbWSDFAttHome">
            <resourceParams>
                <parameter>
                    <name>resourceClass</name>

<value>org.globus.wsrf.samples.rgbwsdfatt.PersistentRgbWSDFAtt</value>

                </parameter>
                <parameter>
                    <name>resourceKeyName</name>
                    <value>{http://rgbwsdfatt.com}RgbWSDFAttKey</value>
                </parameter>
                <parameter>
                    <name>resourceKeyType</name>
                    <value>java.lang.Integer</value>
                </parameter>
                <parameter>
                    <name>cacheLocation</name>

<value>java:comp/env/services/RgbWSDFAttService/cache</value>

                </parameter>
            </resourceParams>
        </resource>
      <resource name="cache"
                type="org.globus.wsrf.utils.cache.LRUCache">
            <resourceParams>
                <parameter>
                    <name>timeout</name>
                    <value>600</value>
                </parameter>
            </resourceParams>
       </resource>
    </service>
.....

I thought the timeout should remove the reference, but it seems not. Can I (How can I) remove the used resource by setting the configuration file?
