Steps for Execution
- Save this file as example.jsp in your eclipse IDE.
- Now select this jsp file, right mouse click and select Run as ->Run on server
Output
When the execution process is completed successfully we will get the following output :
In the above example the item attribute is used define the tokens. it will iterate over tokens separated by delimiter. In the above example we use the “, & ” delimiters to tokenize the string.
