Retrieve logger
To retrieve the current CRM Session object you have to use getCRMSession() method which is implemented in com.crm.businessobject.CRMBase super class. Note that all CRMBO, CRMUI, CRMProcess and CRMAPIBean classes extend CRMBase.
| Code Block |
|---|
| title | Retrieve CRM Session |
|---|
| collapse | true |
|---|
|
public CRMDO copy(CRMDO dto)
{
CRMSession session = getCRMSession()</dependencies>
|
Disable standalone configuration:
Add the following in standalone.xml under wildfly\standalone\configuration :
| Code Block |
|---|
| title | Disable standalone configuration |

| collapse | true |

|
<subsystem xmlns="urn:jboss:domain:logging:3.0">
<add-logging-api-dependencies value="false"/>
<use-deployment-logging-config value="false"/>
.......
</subsystem> |
Invoke the logger object
If the file extends CRMBase:
| Code Block |
|---|
| title | Use logger |
|---|
| collapse | true |

|
public void doSomething(CRMDOAccountingPeriod accountingPeriod) throws Exception {
logger.debug("Invoked doSomething()");
...
} |
Use logger
After retrieving the CRM Session, you can use it to get information about the logged in user, the server, the database and the general and formatting settings.If the file does not extend CRMBase:
| Code Block |
|---|
| title | Example 1 - Logged In UserUse logger |
|---|
| collapse | true |
|---|
|
public CRMDOvoid copydoSomething(CRMDOCRMDOAccountingPeriod dtoaccountingPeriod) throws Exception {
CRMSessionLogger sessionlogger = LogUtil.getLogger(getCRMSession(), getClass());
iflogger.debug( dto instanceof CUSTOMCRMDORentalTypeProduct)
{
CUSTOMCRMDORentalTypeProduct oldProduct = (CUSTOMCRMDORentalTypeProduct) dto;
CUSTOMCRMDORentalTypeProduct newProduct = (CUSTOMCRMDORentalTypeProduct)oldProduct.clone();
newProduct.setCreatedDate(getCurrentDate());
newProduct.setCreatedByUnit(session.getUnit());
newProduct.setCreatedByUser(ejbSession.getLoggedUser"Invoked doSomething()");
...
} |
If the file is not related to an organisation:
| Code Block |
|---|
| title | Use logger |
|---|
| collapse | true |
|---|
|
public void doSomething(CRMDOAccountingPeriod accountingPeriod) throws Exception {
Logger logger = LogUtil.getLogger(getClass());
logger.debug("Invoked doSomething()");
...
} |
If the method/file is asynchronous:
| Code Block |
|---|
| title | Use logger |
|---|
| collapse | true |
|---|
|
@Asynchronous
public void execute(@Observes(during=TransactionPhase.AFTER_SUCCESS) WorkflowRuleEvent event) {
setLogger(event.getSession());
newProductlogger.setUpdatedByUnit(null);
newProduct.setUpdatedByUser(nulldebug("Invoked execute()");
newProduct.setUpdatedDate(null);
