Underscore in OGNL expression not working - struts2

Question

I am surprised that underscore ("_") is not working in OGNL.
In below sample all properties are processed on OGNL/ValueStack, except property name appfull_name due to underscore.
Code sample below
POJO SampleSdmAppsTabObj.java
import java.io.*;
import javax.persistence.*;
#SuppressWarnings("serial")
#Entity
#Table(name="SDM_APPS")
#IdClass(SdmAppsPkeyObj.class)
public class SdmAppsTabObj implements Serializable
{
//#Id
String orgid;
//#Id
String asnid;
String appfull_name;
String description;
public SdmAppsTabObj(){}
public SdmAppsTabObj
(
String inOrgId,
String inAsnId,
String inAppFullName,
String inDescription
)
{
this.OrgId = inOrgId;
this.AsnId = inAsnId;
this.AppFullName = inAppFullName;
this.Description = inDescription;
}
*/
public String getOrgid() { return orgid; }
public String getAsnid() { return asnid; }
public String getAppfullname() { return appfull_name; }
public String getDescription() { return description; }
public void setOrgid(String inOrgId ) { this.orgid = inOrgId; }
public void setAsnid(String inAsnId ) { this.asnid = inAsnId; }
public void setAppfullname(String inAppFullName ) { this.appfull_name = inAppFullName; }
public void setDescription(String inDescription ) { this.description = inDescription; }
//Override equals() and hashCode()
#Override
public boolean equals(Object inObject)
{
if (this == inObject) { return true; }
if (inObject == null) { return false; }
if (!(inObject instanceof SdmAppsTabObj)) { return false; }
SdmAppsTabObj other = (SdmAppsTabObj) inObject;
if( orgid == null )
if( other.orgid != null ) { return false; }
else if( !orgid.equals(other.orgid) ) { return false; }
if( asnid == null )
if( other.asnid != null ) { return false; }
else if( !asnid.equals(other.asnid) ) { return false; }
return true;
}
public int hashCode()
{
final int prime = 31;
int result = 1;
result = prime * result + ((orgid == null) ? 0 : orgid.hashCode());
result = prime * result + ((asnid == null) ? 0 : asnid.hashCode());
return result;
}
}
SdmAppsAction.java

SdmAppsTabObj lSdmAppsTabObj = new SdmAppsTabObj();
public String execute() throws Exception {
return SUCCESS;
}
public SdmAppsTabObj getModel() {
return lSdmAppsTabObj;
}
}

Answer 1

The getter of your appfull_name is
public String getAppfullname();
instead of:
public String getAppfull_name();
Also, the name of setter is not correct.
