Support Java 8 compatibility [ticket #8432] Fixed groupId Porting to DataMiner service Updated dependencies Updated to Liferay 6.2 ufor the submitQuery the file result management has been modified. The file is retrieved from the statistical. GWTdbManagerServiceImpl, GxtBorderLayoutPanel, ComputationOutput, SubmitQueryResultWithFileFromServlet modified. UriResolver used to generate an http link from smp url. Dependency added in the pom file. bug fixed for ehcache. The operation of the cache-diskstore pair seems not operate in a correct way when retrieving a big object composed of many data. When a big object is retrieved, some data, previously stored, have been corrupted. In order to solve the problem, a safe procedure has been implemented that, once recovered the data from cache, checks if the data are corrupt. If yes, they need to be recovered again.GWTdbManagerServiceImpl class modified. GWTdbManagerServiceImpl class modified: 1)parameter eternal changed from false to true value in such a way data never expire.Data will be always in cache. 2) method insertDataIntoCache changed in order to add a check on key. If cache contains it then the related element is added in cache. samplings and submitQuery changed in order to return as a result a map with column values truncated to 255 characters and a file with the whole columns values in order to manage so to manage big data properly and the conversion of a geometry data type in a multipolygon representation applying the function st_astext().Classes GWTdbManagerServiceImpl, GxtBorderLayoutPanel and SamplingResultWithFileFromServlet changed in order to manage the truncated map and the file recovered from the statistical through a smt url and converted in a http url. dependencies modified in pom file: - dependency xalan modified in provided in order to use the lib available in the portal. - dependency jakarta-regexp added in order to not use the package regexp in xalan - removed an aslcore dependency because duplicated. - total number rows added in the header of the result related to the submit Query operation: classes ComputationOutput,SubmitQueryResultWithFileFromServlet,GxtBorderLayoutPanel, GWTdbManagerServiceImpl modified. - class Result modified in order to implemet IsSerializable and not Serializable - pom file modified in order to use gwt 2.6.1 with scope compile and not use gwt from the portal bom file. user timeout session management generating a SessionExpiredException in order to show the session checker dialog and redirect to login. Class StatisticalManagerException created in order to manage exceptions generated from the statistical caching on sampling, smartSampling and submitQuery requests added. bug fixed in servlet in sbmitQuery method generated when a map is retrieved from a statisticalmanager and a user clicks cancel button. data refresh added for sampling, smartSampling and submitQuery operations. cache name changed in DBCache. batch processing (thread) added to recover all data in the tree and the tables list. data cached adding in a key the scope within a user uses the portlet. data refresh improved in the tree panel in order to implement the cascade refresh using a thread.Queue mechanism added to make asynchronous the communication with the ThreadDataLoader. For the functionality of TablesList the "canc" button of the window that displays the tables list has been removed and has been added icon at the top of the window (as well as in submitQuery and Samplings dialogs). In addition, on top of the window has been also removed icon that minimizes window and has been added icon that maximizes the window. bug fixed in class GxtBorderLayout in order to manage the copy of grid elements correctly. An element copy has been managed setting a grid property named disbleTextSelection and not through the double click and the edit event. counter added in order to count the cache hit number and the satistical manager computation number, the cache query sampling hit number and the satistical manager query sampling computation number to perform statistics about the effectiveness of the cache. for submitQuery operation attributes names added in the csv file. bug fixed for the submit query operation if at the same time a refresh query operation is performed. GWTdbManagerServiceImpl and GxtBorderLayput classes modified. top header in the portlet made invisible. GxtBorderLayout class modified. bug fixed in DatabasesResourcesManager component and related to samplings operations and the related column values truncation.If quote is truncated the parsecvsString in servlet does not work fine. Row, GxtBorderLayoutPanel, GWTdbManagerServiceImpl, GxtBorderLayoutPanel classes modified to manage in a correct way the exception generated in class Row while parsing a csv row in a values list for samplings operations. samplings operations, show create table and table details made available. Interface enhancement first release
