This is bascially an editor in which i can type a title and text
If it type <script>alert(10)</script>
I want to avoid this.
I tried adding the following to the web.xml :
<context-param>
<param-name>defaultHtmlEscape</param-name>
<param-value>true</param-value>
</context-param>
But it didnt work. Probably because this only works with forms.
Please guide Is there any way which spring provides so that i dont need to handle this manually ?
Thanks
