Working With Resource Versions

Other than implementation from the Logi JReport Server UI, developer users are also allowed to manage versions using Logi JReport Server API.

Program examples to show how to publish a report to the versioning system, how to run a report, and how to publish a catalog/report can be found in the <install_root>\help\samples\APIServer folder.

Below is a list of the sections covered in this topic:

Applying an Archive Policy

You may find that whenever you create catalog/report template versions, or report result versions, an archive policy is applied. The archive policy is a series of settings for controlling whether or not to use multiple versions for a specific resource, for specifying the maximum version amount and archive location, and for controlling whether or not to auto-delete versions after a certain period of time.

Here are some parameters that you will need when specifying your archive policy:

Parameters	Values	Description	Parameters	Values	Description
APIConst.TAG_ENABLE_ARCHIVE_POLICY	true /false	Whether or not to apply a new archive policy.
APIConst.TAG_AUTO_ARCHIVE	true /false	Whether or not to auto-archive the viewed result.
APIConst.TAG_ARCHIVE_LOCATION	0	Built-in version folder is used as the result archiving location.
	1	The My Reports folder is used as the result archiving location.
			APICONST. TAG_ARCHIVE_MY_DESTINATION		Sub folder name in the My Reports folder for this user. For example, /rtp100, which means to output the file to /USERFOLDERPATH/<userid>/rtp100.
	2	The Public Reports folder is used as the result archiving location.
			APICONST. TAG_ARCHIVE_PUBLIC_DESTINATION		Sub folder name in the Public Reports folder for all the users. For example, /ActimizeTest/rtp100
APIConst.TAG_REPLACE_OLD_VERSION	true /false	Whether or not to replace the previous version.
APIConst.TAG_ARCHIVE_NEW_VERSION	true /false	Whether or not to archive the next version as a new version.

APICONST. TAG_NEED_MAXVERSION	0 or N	The number of versions to keep for this resource result.
APICONST.TAG_NEED_EXPIRE	true /false	Whether or not to auto delete this version.
APIConst.TAG_EXPIRE_METHOD	0	Version expires after a number of days.
			APIConst.DAY_EXPIRE	Number	The number of days until a version expires.
	1	Version expires after a certain date.
			APIConst.TAG_EXPIRE_YEAR	Number	The year of expiration.
			APIConst.TAG_EXPIRE_MONTH	Number	The month of expiration.
			APIConst.TAG_EXPIRE_DATE	Number	The date of expiration.

Scheduling Report Result to the Versioning System

You can use the Java class HttpRptServer with the following methods to schedule report result to the versioning system: runTask(), and submitScheduledTask().

There is a Hashtable argument for these two methods, which includes the parameters used for running tasks. Here are some parameters that you will need when specifying your Hashtable for scheduling to version:

Parameters	Values	Description	Parameters	Values	Description
APICONST.TAG_TO_VERSION	true /false	Whether or not to schedule to the versioning system.
			APICONST.TAG_TO_VERSION_EXCEL	true /false	Whether or not to schedule to an Excel version.
			APICONST.TAG_TO_VERSION_HTML	true /false	Whether or not to schedule to an HTML version.
			APICONST.TAG_TO_VERSION_PDF	true /false	Whether or not to schedule to a PDF version.
			APICONST.TAG_TO_VERSION_PS	true /false	Whether or not to schedule to a PostScript version.
			APICONST.TAG_TO_VERSION_RSD	true /false	Whether or not to schedule to a Page Report Result version.
			APICONST.TAG_TO_VERSION_RST	true /false	Whether or not to schedule to an rst version.
			APICONST.TAG_TO_VERSION_RTF	true /false	Whether or not to schedule to an rtf version.
			APICONST.TAG_TO_VERSION_TXT	true /false	Whether or not to schedule to a TEXT version.
			APICONST.TAG_TO_VERSION_XML	true /false	Whether or not to schedule to an XML version.

Obtaining Version Information

You will be able to fetch version records with the following function calls:

Get the resource manager from the HttpRptServer:
public ResourceManager getResourceManager()
Then use the following methods to obtain a version:
- Report version
  getReportVersions(String userID, String rptName)
- Report Result version
  getResultVersion(String userID, String rptName, int versionNumber)
- Catalog version
  getCatalogVersions(String userID, String catName)
- Result version
  getResultDocVersions(String userID, String resultDocName)
- Dashboard version
  getReportVersions(String userID, String dashboardName)
- Library component version
  getLCVersions(String userID, String lcName)

Note: userID is only used for checking privilege in this method, and not for filtering the submitter.
