Hi Lishan,

I've copied this to the Epsilon newsgroup, so other users can read the

Comments below.

Great. You'll also need to tell Epsilon that mchstTool is indeed a tool:

1) Open the MANIFEST.MF file in the META-INF directory of the project
that contains your hst package.

2) Click the Dependencies tab, and select Add under Required Plug-in.
Type "org.eclipse.epsilon.common.dt" Click Ok.

3) Click the Extensions tab, and select Add. Scroll down and select the
"org.eclipse.epsilon.common.dt.tool" entry. Click Ok.

4) Select the entry labelled (tool) in the left-hand tree. Type the
fully-qualified path to the class that represents your tool. In your
case, this is: hst.mchstTool

5) Give the tool a defaultName, for example: mchstTool

6) Save the contents of the editor (File | Save).

Your EWL code looks fine.

I'll update the documentation with some more instructions, and I'll see
if Dimitrios wants to change anything too.
