Can't create map in velocity

Question

In my velocity template i am creating map like this :

#set($mymap.Map={"key":"value","key2":"value2"})

I think it must work according to the documentation of velocity, but there is next error:

HTTP Status 500 - Could not load Velocity template for URL [editEmployee.vsl]; nested exception is org.apache.velocity.exception.ParseErrorException: Lexical error: org.apache.velocity.runtime.parser.TokenMgrError: Lexical error at line 44, column 36. Encountered: "{" (123), after : ""

type Exception report

There is my pom with velocity:

<dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity</artifactId>
            <version>1.6.2</version>
        </dependency>   
        <dependency>
            <groupId>velocity-tools</groupId>
            <artifactId>velocity-tools</artifactId>
            <version>2.0</version>
        </dependency>
        <dependency>
            <groupId>velocity-tools</groupId>
            <artifactId>velocity-tools-generic</artifactId>
            <version>1.4</version>
        </dependency>
        <dependency>
            <groupId>commons-collections</groupId>
            <artifactId>commons-collections</artifactId>
            <version>3.1</version>
        </dependency>

Why do you use both velocity-tools 2.0 and velocity-tools-generic 1.4? — Sergiu Dumitriu, Aug 26 '12 at 01:46

This is supposed to work in Velocity. I tried the following simple snippet, both in 1.7 and 1.6.2, and it printed the correct response:

#set ($mymap = {})
#set ($mymap.Map={"key":"value","key2":"value2"})
$mymap

Prints:

{Map={key=value, key2=value2}}

So, make sure that the error is indeed here:

Does the suggested error position (line 44, column 36) match the line you quoted?
Does the error remain if you comment out that line?
Does another component from Spring pre-process the template, so that in the end Velocity sees another thing than what you think it does?
- Does the error remain if you re-format the code with some more whitespaces?
Does the error remain if you use this alternative syntax?

#set($discard = $mymap.put('Map', {'key':'value','key2':'value2'}))

Thanks a lot for answer Dumitriu!I found out my mistake.The reason was the version of velocity.I thought I included 1.7 but it was 1.4. — ema, Aug 28 '12 at 17:51
