Hi This post regarding h:dataTable rowClasses attribute.

Hope this will be useful for you also as i have used in my code.

Out put should be a Table with row colored depending on the status of the each student.

so in my jsp i addded
<style>
.redcolor{
background-color:rgb(250,128,114);
}
.blueColor{
background-color:rgb(135,206,250);
}
.yellowColor{
background-color:rgb(255,255,224);
}
.whiteColor{
background-color:white;
}
</style>
within the head tag and the table as
<h:dataTable id="UnAssignedTable" width="100%" value="#{studentAGAssign.studentBasicVOList}" var="item" rowClasses="#{studentAGAssign.rowColor}">
</h:dataTable>

In my bean file i added rowColor as String variable with its getter and setter methods.
and initialize the rowColor variable with the css class name specified in the jsp page according to each student status which is in the below java code using string builder:
StringBuilder strBuild=new StringBuilder();


for(StudentBasicVO student:studentBasicVOList){
strBuild.append(getRowColor(student));
strBuild.append(',');
}
int length= strBuild.length();
if(length>0){
strBuild.deleteCharAt(length-1);
// strBuild.append(';');
rowColor=new String(strBuild);
}
public String getRowColor(StudentBasicVO stu){
String rowColor="whiteColor";
if(stu.isApplied()){
rowColor="yellowColor" ;
}else if(stu.isConfirmed()){
rowColor="blueColor";
}else if(stu.isCompleted()){
rowColor="redColor";
}


return rowColor;
}
