Page:
<apex:page controller="theController">
<apex:messages />
<apex:form >
<apex:pageBlock mode="edit" id="block">
<apex:pageBlockSection >
<apex:pageBlockSectionItem >
<apex:outputLabel for="searchText">Search Text</apex:outputLabel>
<apex:panelGroup >
<apex:inputText id="searchText" value="{!searchText}"/>
<apex:commandButton value="Go!" action="{!doSearch}"
rerender="block" status="status"/>
</apex:panelGroup>
</apex:pageBlockSectionItem>
</apex:pageBlockSection>
<apex:actionStatus id="status" startText="requesting..."/>
<apex:pageBlockSection title="Results" id="results" columns="1">
<apex:pageBlockTable value="{!results}" var="l"
rendered="{!NOT(ISNULL(results))}">
<apex:column value="{!l.name}"/>
<apex:column value="{!l.email}"/>
<apex:column value="{!l.phone}"/>
</apex:pageBlockTable>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:page>
You are almost there.
Modify like this:
ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.FATAL, 'my error msg');
ApexPages.addMessage(myMsg);
-----OR------
ApexPages.addMessage( new ApexPages.Message(ApexPages.Severity.FATAL, 'my error msg'));

Hope it helps.
Another way to show your message is:
public class Extension
{
//Declare a property in your apex class
public String msg{get;set;}
public void method()
{
//assign value to that property
msg=' Message detail';
}
}
<apex:page standardController="sObject" extensions="Extension">
<apex:form >
<apex:pageBlock >
<apex:outputText value="{!msg}"></apex:outputText>
</apex:pageBlock>
</apex:form>
</apex:page>
Give some id to the <apex:messages /> and then rerender in the action you are calling.
For example
<apex:messages id="myMessages"/>
and modify
<apex:commandButton value="Go!" action="{!doSearch}" rerender="block,myMessages" status="status"/>
This will solve the problem.
