Approval Process through mail in OIM

Question

Hi,
I need your views for the best way to meet this requirement:
Let's say a user is provisioned to a resource and resource has been configured with a approval process. The System Administrator 'xelsysadm' approval has been set to auto-complete so that step of approval is done automatically and the approval goes to the main approver of the resource. Now i require to send the requests generated in last 30 minutes only which are meant for an approver by grouping them and then sending them in a mail in HTML format to take further action.
Please do reply by your views on how to implement this.
Thanks

Answer 1

Thanks for the idea,
I need your help as i am facing issues in implementing it.
For Initializing the Factory Class with a Digital Signature i used this code
ConfigurationClient.ComplexSetting config = ConfigurationClient.getComplexSettingByPath("Discovery.CoreServer");
final Hashtable env = config.getAllSettings();
tcSignatureMessage moSignature = tcCryptoUtil.sign("xelsysadm","PrivateKey");
tcUtilityFactory m_utilFactory = new tcUtilityFactory(env, moSignature);
and updated the xlconfig.xml file as such
<KeyStore>
     <Location>.xlkeystore</Location>
     <Password encrypted="true">JfDl5Dgc48/6pVaOHW+6Qg==</Password>
     <Type>JKS</Type>
     <Provider>sun.security.provider.Sun</Provider>
</KeyStore>
<Keys>
     <PrivateKey>
          <Alias>xell</Alias>
          <Password encrypted="true">JfDl5Dgc48/6pVaOHW+6Qg==</Password>
     </PrivateKey>
</Keys>
But on executing the code this error is displayed:
com.thortech.xl.crypto.tcCryptoException: KeyStore File : .\config\xl.keystore missing.
     at com.thortech.xl.crypto.tcCryptoHelper.loadKeyStore(Unknown Source)
     at com.thortech.xl.crypto.tcDefaultSignatureImpl.initKeyStore(Unknown Source)
     at com.thortech.xl.crypto.tcDefaultSignatureImpl.sign(Unknown Source)
     at com.thortech.xl.crypto.tcCryptoUtil.sign(Unknown Source)
at com.reconciliation.UserReconciliation.connect(UserReconciliation.java:49) (this is line tcSignatureMessage moSignature = tcCryptoUtil.sign("xelsysadm","PrivateKey"); of the code)
What i observed is that the keystore file it is searching for .\config\xl.keystore is not there as it is .xlkeystore in config and the same is mentioned in the config file also.
Can you please tell me in what step i am wrong or if there is anything that i am missing.
Thanks
