12 | 10 | Manuel Madrid | h3. What did I get done this week? |
13 | 7 | Manuel Madrid | |
14 | 8 | Manuel Madrid | This week I have been learning the procedures for generating plugin installation packages. I found some problems when trying to configure the downloading URL of the package but finally I got it. As Joaquín, my mentor, suggested, I opened an issue ticket explaining the problem because it could be useful for other developers. |
15 | 3 | Manuel Madrid | |
16 | 8 | Manuel Madrid | I uploaded the installation package to the project site at: |

19 | 3 | Manuel Madrid | |
20 | 1 | Manuel Madrid | I also opened a ticket asking the gvSIG project admins for adding it to the official package repository: |

24 | 10 | Manuel Madrid | h3. What do I plan on doing next week? |
25 | 9 | Manuel Madrid | |
26 | 9 | Manuel Madrid | I will test the package and will create user documentation for the current functionalities. |

34 | 10 | Manuel Madrid | h3. What did I get done this week? |
35 | 3 | Manuel Madrid | |
36 | 9 | Manuel Madrid | I fixed some bugs related with the detection of the columns types. Now the plugin already recognize the following types: integer, long, float and double. The rest of the data is managed as string. |
37 | 1 | Manuel Madrid | |
38 | 9 | Manuel Madrid | I finally decided to go for the spatial support. I made some changes and now the plugin is already able to load tables containing coordinates (X,Y and Z) as point layers. |
39 | 3 | Manuel Madrid | |
40 | 11 | Manuel Madrid | h3. What do I plan on doing next week? |
41 | 1 | Manuel Madrid | |
42 | 9 | Manuel Madrid | I will get to know how to generate the plugin package. Then I will generate an addon that could be installed from the gvSIG addons manager. I will check that it can be installed on the last gvSIG 2.1 build (2227). Finally I will upload the package to the gvSIG official repo so it can be installed by everyone. |

45 | 3 | Manuel Madrid | |
46 | 9 | Manuel Madrid | I had some problems trying to use the latest version of the gvSIG library org.gvsig.tools. I wanted to use it as it has some interesting bugfixes but I finally couldn't. |
47 | 3 | Manuel Madrid | |
48 | 9 | Manuel Madrid | Since those changes won't be available until the next gvSIG build release, Joaquín, my mentor, suggested to take a workaround in the meantime. |

52 | 11 | Manuel Madrid | h3 What did I get done this week? |
53 | 1 | Manuel Madrid | |
54 | 9 | Manuel Madrid | I adapted the source code of the CSV provider in order to be able to read Excel spreadsheets using the jexcelapi library. Finally I used more amount of source code of the CSV provider than expected. |
55 | 1 | Manuel Madrid | |
56 | 9 | Manuel Madrid | I converted to Excel file format through LibreOffice the following files: |
57 | 9 | Manuel Madrid | * http://downloads.gvsig.org/download/geodata/tables/CSV/poblacionINE.csv.zip |
58 | 9 | Manuel Madrid | * http://downloads.gvsig.org/download/geodata/tables/CSV/torrent_4.csv.zip |
59 | 7 | Manuel Madrid | |
60 | 9 | Manuel Madrid | I uploaded them to the plugin folder and used them for testing the data loading. |
61 | 7 | Manuel Madrid | |
62 | 9 | Manuel Madrid | Now it is already possible to load them as tables in gvSIG with minor issues that I will try to fix the next week. |
63 | 1 | Manuel Madrid | |
64 | 11 | Manuel Madrid | h3. What do I plan on doing next week? |
65 | 7 | Manuel Madrid | |
66 | 9 | Manuel Madrid | I will fix some issues affecting the detection of the column types. |
67 | 1 | Manuel Madrid | |
68 | 9 | Manuel Madrid | Depending on how long takes me to fix this issues I will consider to address the implementation of the spacial data support, despite it was initially planned in the next iteration, some weeks later. |

71 | 1 | Manuel Madrid | |
72 | 9 | Manuel Madrid | I thought I could get more information from the Excel file than I finally got, as I couldn't get the information regarding the column type and the headers, in case they had. |
73 | 1 | Manuel Madrid | |
74 | 9 | Manuel Madrid | This made me spend more time than expected studying the jexcelapi needlessly as I finally reused some of the CSV provider source code. I have to say that this made me think if using the jexcelapi library was the right decision but I finally decided to carry on with it. |

78 | 11 | Manuel Madrid | h3. What did I get done this week? |
79 | 7 | Manuel Madrid | |
80 | 9 | Manuel Madrid | * Created the maven multi-mode structure for the project. |
81 | 9 | Manuel Madrid | * Added the library modules and configuration files needed to compile and deploy the gvSIG plugin. |
82 | 9 | Manuel Madrid | * Uploaded the project to the SVN: |
83 | 9 | Manuel Madrid | https://devel.gvsig.org/svn/gvsig-jexcel |
84 | 1 | Manuel Madrid | |
85 | 3 | Manuel Madrid | The SVN is also available from the gvSIG Redmine: |

87 | 3 | Manuel Madrid | |
88 | 11 | Manuel Madrid | h3. What do I plan on doing next week? |
89 | 3 | Manuel Madrid | |
90 | 7 | Manuel Madrid | Next week I will try to have a preliminar version of the plugin that allows just to load data, without taking into account types and parameters. |
91 | 7 | Manuel Madrid | |
92 | 11 | Manuel Madrid | h3. Am I blocked on anything? |
93 | 7 | Manuel Madrid | |
94 | 12 | Manuel Madrid | Had problems to find where to register the new data provider. |
95 | 12 | Manuel Madrid | |
96 | 12 | Manuel Madrid | It was specially time-consuming to get familiar with the maven project structure. |
97 | 12 | Manuel Madrid | |
98 | 12 | Manuel Madrid | I also found some problems to upload the source code to the SVN. |
99 | 12 | Manuel Madrid | |
100 | 12 | Manuel Madrid | I was not sure if some aspects of the maven general configuration are correct. |
101 | 3 | Manuel Madrid | |
102 | 9 | Manuel Madrid | Finally I could fix all those problems so I made the expected progress. |

106 | 11 | Manuel Madrid | h3. What did you get done this week? |
107 | 3 | Manuel Madrid | |
108 | 9 | Manuel Madrid | In order to implement the Excel data provider for gvSIG I will use as a basis a Java library that provides access to Excel data. |
109 | 7 | Manuel Madrid | |
110 | 9 | Manuel Madrid | I considered the following alternatives: |
111 | 9 | Manuel Madrid | * POI-HSSF and POI-XSSF - Java API To Access Microsoft Excel Format Files |
112 | 9 | Manuel Madrid | * SmartXLS for Java |
113 | 9 | Manuel Madrid | * Java Excel API |
114 | 7 | Manuel Madrid | |
115 | 9 | Manuel Madrid | I finally decided to go for the last one as it is powerful enough and it looks quite simple. It seems that this project doesn't have activity since 2010 but I hope this is not a problem. |

122 | 7 | Manuel Madrid | I've got a project within the gvSIG project infrastructure: |

126 | 7 | Manuel Madrid | The source code will be stored at: |

129 | 11 | Manuel Madrid | h3 What do you plan on doing next week? |
130 | 7 | Manuel Madrid | |
131 | 9 | Manuel Madrid | I plan to create the Maven projects infrastructure. I will use as a basis the following gvSIG projects: |
132 | 9 | Manuel Madrid | * gvSIG data provider for DGN |
133 | 3 | Manuel Madrid | https://devel.gvsig.org/redmine/projects/gvsig-dgn |
134 | 9 | Manuel Madrid | * gvSIG data provider for DXF |
135 | 3 | Manuel Madrid | https://devel.gvsig.org/redmine/projects/gvsig-dxf |
136 | 3 | Manuel Madrid | |
137 | 9 | Manuel Madrid | I also will use the gvSIG CVS data provider to compose the project skeleton. |
138 | 3 | Manuel Madrid | |
139 | 11 | Manuel Madrid | h3. Are you blocked on anything? |

141 | 9 | Manuel Madrid | Not, so far. |
