I am currently having a add profile portlet , there is no problem adding into the mysql database.
However when you are trying to display it . You would have to restart the server.
I read that it got something to do with lifeRay caching database entity at the start of running the server. Then use it.
Is there anyway to ask the Liferay to recache(the particular table) again after we updated data into the database?

Hello Henry,
If you are using service builder, this problem should not come! Are you sure?
HTH.
Thanks and Regerds,

Hi
By service builder , you meant going into the service.xml file pressing the build service ,
then going into localserviceImpl to add in addStudent method then build service again
I am using eclipse ide btw.

Which log do you need?
Because if you check in mysql the table would have data that is just inputted.

We need not to restart the server is you want to display the stored data in database...
but if you delete/add data to database externally (ie not via programing or by using mySqlQuery browser ) then u need to clear the database cache.(control panel>server administation>clear database cache),

This is the code I use to Add into database
Method I use to display
For example I add test
before in the database
After in the database
What it look like
After restart server
Is it because of this method I created in studentLocalServiceImpl.java
public void addStudent(String name , int gender , String email , String description ) throws com.liferay.portal.kernel.exception.SystemException
{
Student tempstu = StudentLocalServiceUtil.createStudent(CounterLocalServiceUtil.increment());
tempstu.setDescription(description);
tempstu.setName(name);
tempstu.setGender(gender);
tempstu.setEmail(email);
StudentLocalServiceUtil.updateStudent(tempstu);
}
Method I use to display
Display Profile
<br>
<br>
Select a student:
<%
try
{
int index = 1;
int count = StudentLocalServiceUtil.getStudentsCount();
List<student> studentList = StudentLocalServiceUtil.getStudents(0,count);
for (Student tempStudent : studentList)
{
String tempName=tempStudent.getName();
%>
<br>
<form action="${displayProUrl}" method="post">
<aui:input type="hidden" name="redirectURL" value="<%= renderResponse.createRenderURL().toString() %>" />
<input type="radio" name="name" value="<%out.print(tempName);%>"><%out.print(tempName);%>
<%
index++;
}
%>
<br>
<input type="submit" value="Select">
</form>
<% }
catch(Exception e)
{
e.printStackTrace();
}
%>
</student>

Your code seems to be correct and it is not because you have written this method in studentLocalServiceImpl.java because this is correct approach.
