The DOC_INFO service provides a good example of how services, queries, and templates work together. This section covers the following topics:
The following figures show the DOC_INFO service definition from the IdcHomeDir/resources/core/templates/std_services.htm file:
The following is an example of the DOC_INFO service definition, displayed in a text editor and Web browser.

The following table describes the attributes of the DOC_INFO service:
Attribute | Value | Description |
---|---|---|
Service class | DocService | This service is providing information about a content item. |
Access level | 33 | 1 = The user requesting the service must have Read permission on the content item.
32 = This service can be executed with the executeService Idoc Script function. |
Template page | DOC_INFO | This service uses the DOC_INFO template (doc_info.htm file). The results from the actions will be merged with this template and presented to the user. |
Service type | null | This service is not a subservice. |
Subjects notified | null | No subjects are affected by this service. |
Error Message | !csUnableToGetRevInfo | If this service fails on an English Content Server system, it returns the error message string:
Unable to retrieve information about the revision |
The DOC_INFO service executes the following ten actions:
Action 1 takes the following form:
Action 1 - 5:QdocInfo:DOC_INFO:2:!csItemNoLongerExists2
5 : Select cache query action that retrieves information from the database using a query.
QDocInfo : This action retrieves content item information using the QDocInfo query in the query.htm file.
DOC_INFO : The result of the query is assigned to a ResultSet called DOC_INFO and stored for later use.
2 : The Check result non-empty control mask specifies that the query must return a record, or the action fails.
!csItemNoLongerExists2 : If this action fails on an English Content Server system, it returns the error message string:
This content item no longer exists
Action 2 takes the following form:
Action 2 : 3:mapNamedResultSetValues:DOCINFO,dStatus,dStatus,dDocTitle,dDocTitle:0:null
3: Java method action specifying a module that is a part of the Java class implementing the service.
mapNamedResultSetValues : This action retrieves the values of dStatus and dDocTitle from the first row of the DOC_INFO ResultSet and stores them in the local data. (This increases speed and ensures that the correct values are used.)
DOC_INFO,dStatus,dStatus,dDocTitle,dDocTitle : Parameters required for the mapNamedResultSetValues action.
0 : No control mask is specified.
null : No error message is specified.
Action 3 takes the following form:
Action 3 : 3:checkSecurity:DOC_INFO:0:!csUnableToGetRevInfo2(dDocName)
3 : Java method action specifying a module that is a part of the Java class implementing the service.
checkSecurity : This action retrieves the data assigned to the DOC_INFO ResultSet and evaluates the assigned security level to verify that the user is authorized to perform this action.
DOC_INFO : ResultSet that contains the security information to be evaluated by the checkSecurity action.
0 : No control mask is specified.
!csUnableToGetRevInfo2(dDocName) : If this action fails on an English Content Server system, it returns the error message string:
Unable to retrieve information for '{dDocName}.'
Action 4 takes the following form:
Action 4 : 3:getDocFormats:QdocFormats:0:null
3 : Java method action specifying a module that is a part of the Java class implementing the service.
getDocFormats : This action retrieves the file formats for the content item using the QdocFormats query in the query.htm file. A comma-delimited list of the file formats is stored in the local data as dDocFormats.
QdocFormats : Specifies the query used to retrieve the file formats.
0 : No control mask is specified.
null : No error message is specified.
Action 5 takes the following form:
Action 5 : 3:getURLAbsolute::0:null
3 : Java method action specifying a module that is a part of the Java class implementing the service.
getURLAbsolute : This action resolves the URL of the content item and stores it in the local data as DocUrl.
blank : This action takes no parameters.
0 : No control mask is specified.
null : No error message is specified.
Action 6 takes the following form:
Action 6 : 3:getUserMailAddress:dDocAuthor,AuthorAddress:0:null
3 : Java method action specifying a module that is a part of the Java class implementing the service.
getUserMailAddress : This action resolves the e-mail address of the content item author.
dDocAuthor,AuthorAddress : This action passes dDocAuthor and AuthorAddress as parameters.
0 : No control mask is specified.
null : No error message is specified.
Action 7 takes the following form:
Action 7 : 3:getUserMailAddress:dCheckoutUser,CheckoutUserAddress:0:null
3 : Java method action specifying a module that is a part of the Java class implementing the service.
getUserMailAddress : This action resolves the e-mail address of the user who has the content item checked out.
dCheckoutUser,CheckoutUserAddress : This action passes dCheckoutUser and CheckoutUserAddress as parameters.
0 : No control mask is specified.
null : No error message is specified.
Action 8 takes the following form:
Action 8 : 3:getWorkflowInfo:WF_INFO:0:null
3 : Java method action specifying a module that is a part of the Java class implementing the service.
getWorkflowInfo : This action evaluates whether the content item is part of a workflow. If the WF_INFO ResultSet exists, workflow information is merged into the DOC_INFO template.
WF_INFO : This action passes WF_INFO as a parameter.
0 : No control mask is specified.
null : No error message is specified.
Action 9 takes the following form:
Action 9 : 3:getDocSubscriptionInfo:QisSubscribed:0:null
3 : Java method action specifying a module that is a part of the Java class implementing the service.
getDocSubscriptionInfo : This action evaluates if the current user has subscribed to the content item:
If the user is subscribed, an Unsubscribe button is displayed.
If the user is not subscribed, a Subscribe button is displayed.
QisSubscribed : Specifies the query used to retrieve the subscription information.
0 : No control mask is specified.
null : No error message is specified.
Action 10 takes the following form:
Action 10 :
5:QrevHistory:REVISION_HISTORY:0:!csUnableToGetRevHistory(dDocName)
5 : Select cache query action that retrieves information from the database using a query.
QrevHistory : This action retrieves revision history information using the QrevHistory query in the query.htm file.
REVISION_HISTORY : The result the query is assigned to a ResultSet called REVISION_HISTORY. The DOC_INFO template loops on this ResultSet to present information about each revision.
0 : No control mask is specified.
!csUnableToGetRevHistory(dDocName) : If this action fails on an English Content Server system, it returns the error message string:
Ubpnable to retrieve revision history for ''{dDocName}.''
The template page for the DOC_INFO service is the DOC_INFO template. It is important to know what is happening between the files so that you can understand the interactions between the template page and the actions performed in a service.
The definition for the content that the doc_info.htm template contains is located in the IdcHomeDir/components/Folders/resources/std_page.htm file. Code from both files appear in the following markup section:
