Question

SORRY: This is my bad. This error is due incorrect json produce and to Chrome extension “JSONView in Chrome”. See my own answer (I had to answer this myself – as I could not delete the question anymore).

I am using Velocity (Maven version 1.7 of org.apache.velocity) as templating engine, and I want output as follows:

{
   total : 234
}

now when I try:

{
    total : $listing.size()
}

I get an error:

Error: Parse error on line 1:
{   total : 0}
--^
Expecting 'STRING', '}'

and when I try to escape the curly braces:

\{
    total : $listing.size()
\}

I get the escape characters in the final output!:

\{
   total : 234
\}

Answer 1

Sorry this was due incorrect JSON I was producing, which Chrome browser’s extension “JSONView” pointed out to me. This was because my keys were not strings… i.e. I had:

 {total: 0}

but I should’ve had:

 {"total" : 0}
