| Tag Summary |
| session |
Open a Mumps session. This tag should enclode any other MJSP tag. While inside this tag, an M connection
is used to run all the enclosed MJSP tags, in the same M context, i.e. variables and locks are available
between different tags.
Upon closing the session tag, all locks and variables are cleared, and the M connection is released.
The following variable are set in the M context in the beggining of the session:
- %REM - Remote address
- %NAM - HTTP referrer (TBD)
- %FORW - HTTP forwarded for (TBD)
- %HTIP - Host IP
- %RMAD - Remote address (again, for backward compatability)
- %RMHT - Remote host
- %COOK - Cookie
- %PAID - TBD
- JB - The user session id, set by m:setSessionId, if used before.
- %ARG() - A map us the request parameters, passed in the request
|
| setSessionId |
Set the user session ID into the M session. Use this tag to maintain a user sesssion between different requests.
After calling it it will set the M variable "JB" and the JSP variable "_sessid" to the session ID.
|
| set |
Set an M variable.
|
| out |
Print an M expression.
|
| get |
Get the value of an M expression into variable.
|
| exec |
Execute M code.
|
| serverExec |
Execute M code from javascript, on the server.
The code is run in a fresh context.
If in a user session (setSessionId was called before) The M variable "JB" is set in the context.
This code is run through a Servlet in a secure way: Upon handling the page request the M code to run is saved in a temporary global
by a long-one-time-key, which allows executing it.
|
| if |
Perform body if M condition is true (non zero).
|
| while |
Perform body repeatedly while M condition is true (non zero).
|
| query |
Perform M query. This is the way to get tabular data from M and iterate over it (e.g. parse it into an HTML table).
The output expacted from the M code is in the following format:
- List of columns, each one in a line of the format: NAME=column_name,TYPE=column_type (type can be "E" for English, "N" for number, and "H" for Hebrew).
- >>>DATA
- A line for each table row with the column values separated by underscore ('_') character.
For example, to print a table with 4 columns, generate this output from the M code:
NAME=id,TYPE=N
NAME=first,TYPE=E
NAME=last,TYPE=E
NAME=address,TYPE=E
>>>DATA
1_sidney_Levy_Rechasim
2_Yishai_Pinchover_Haifa
3_Uri_Schor_Zichron Ya'akov
