set value for a property of type long using jconsole

I created an mbean I have a property of type long , when I try to set its value from jconsole I get exception

java.lang.illegalArgument:argument type mismatch

becasue its of type long I using number how can I set the value of long from, jconsole, String it works no problems but how about any othert objects like long double etc?

Please help me with this ,
I have mbean here is my code

@Component(value="myServiceConfigration")
@ManagedResource(objectName =MYServiceConfigration.MBEAN_NAME , //
description = "Change MY service settings  ")

public class MYServiceConfigration {
	
	public static final String MBEAN_NAME = "mycompany.mbeans:type=config,name=MYServiceConfiguration";	
	
	private Long sysInfoId=new Long(24689135);
	
	private String user="user";
	
	private String password="password";
	
	public Long getSysInfoId() {
		return sysInfoId;
	}

@ManagedOperation(description = "Set sysInfoId")
    @ManagedOperationParameters({
            @ManagedOperationParameter(description = " sysInfoId", name = "sysInfoId")})
    public void setSysInfoId(Long sysInfoId) {
		this.sysInfoId = sysInfoId;
	}
     
	public String getUser() {
		return user;
	}

@ManagedOperation(description = "Set password")
    @ManagedOperationParameters({
            @ManagedOperationParameter(description = " web service user", name = "user")})
	public void setUser(String user) {
		this.user = user;
	}
	
	
	public String getPassword() {
		return password;
	}

@ManagedOperation(description = "Set password")
    @ManagedOperationParameters({
            @ManagedOperationParameter(description = " web service password", name = "password")})
	public void setPassword(String password) {
		this.password = password;
	}
	
}

for this mbean I can change values using jconsole.

The problem I have is I am unable to update the property sysInfoId using jconsole becasue its of type long , if its a string like the other two properties no problem , but for long I am unable to please advice me is it ok to use fileds other than string in a mbean (JMX)
Please advice me.

I assume the method you use to read your sysId returns a String, but you need a long. Try googling for Java wrapper classes, that should point you in the right direction.

. . . and either pass a String to the Long() constructor in line 9, or use the L at the end of the number.

Thanks passing L at the end worked.

Well done
