I have a question and answer stored in the object. The request comes in the form of a question and I would like to get an attractive appearance of the text for the answer. For example, bold key words, or underlined words.
Is it possible to store such text in the mongo database, or will I have to create a java class that will process all keywords and edit them?
I think you should process the data in class as required.
Database responsibility is to keep the data not the fancy stuff

Good day to all. I am currently building a program that covers the review of product warranty applications. I'm doing it in javaFX using Netbeans. The program has the following scenes:
a screen where the information of each guarantee request is entered. all the information is stored in a table in a database. The interaction between the program and the database is done, in effect, through JDBC.
a screen where you can see a table that shows all the requests that have been saved. if a row is selected, a button that carries the third scene all the data of the request that was selected is enabled.
a screen where all the data of the tests that are made to the selected guarantee application are entered. The results are also stored in another table in the database.
After the application is evaluated, a warranty review report must be generated. Currently this format is generated in pdf from excel. What I want to do is that from the data results of the tests stored in the database I can dynamically generate the pdf formats from the program in javaFX. Is there a plugin to write these documents automatically? I'm good at writing texts in LaTEX, so if there is a way to generate the latex format from the program and call the necessary information from the database, it would be perfect. Thanks in advance for the help. Any indication or idea is welcome.
It seems like you have two core requirements:
Fetch data from the database suitable for reporting
Generate the report(s) in PDF from JavaFX but can fall back to LaTEX
What you really need seems like a PDF library for Java. I can suggest iText and Docmosis as good options (please note I work for Docmosis) - both are commercial for commercial products so you would have to buy.
Assuming you are using one of these libraries, the process for each report is:
execute the query to fetch the appropriate data for the report
manipulate the data if required to make the reporting stage simple
generate the report
Using iText you would write the query, the manipulation code and then the code to layout the report including the data.
Using Docmosis you would write the query, possibly some manipulation code (Docmosis can also work directly with your ResultSet) and the code to execute the report. The layout is designed in the template (Word or Libre Office Writer).
When you mention writing "these documents automatically" I assume you mean creating the PDF file format, which iText and Docmosis can do. If you mean creating the report layout itself, then you always need to design/write something to make the report do what you require.
I hope that helps.
Thank you very much for your response Paul! I had found something related to the libraries you mentioned, and indeed something like what I'm looking for. I notice that you are more in the subject. then, you do not know bookstore, preferably free, that gives me the possibility of doing the following (pseudo code):
take the row from the database
Save the information of that row in the attributes of a created class.
create text1: "the guarantee with reference" + object.attribute1 + "was not approved in view of the physical revision test indicated that" + object.attribute2 + "
create text2: "..."
...
create the text n: "..."
take text 1 and place it in the header of the pdf document
Take text 2, put it in bold and place it in the subtitle
Generate a table and fill it with the content of text 3, 4 ...
compile all information as a pdf, (word file, xls or others if possible)
I am clear that with the libraries that you recommend you can easily make items from
1 to 8, but I do not know if it is possible to enter the texts within a template created, so that the library accommodates all the texts in the respective zones of the template file. I imagine that this can easily be done with Latex, since everything is written in plain text.
I found a library called Java LaTeX Report (JLR) that allows me to do what I want. This information may be useful to someone. Thank you again for your answer Paul, if you consider the libraries that you mention do the job more easily than JLR please let me know!
I have some string data that needs to be printed inside a table in java.
Simply formatting the text is not enough, I need to actually draw the lines of the table, have a title, header, and footer.
From my searches I found that java.swing.JTable would fulfill my conditions, however I do not need to show the table to the user at any point nor do I need to save the table in a file. I only need to print said table via a printer and JTable seems overkill for such a task, not to mention rather complicated.
Is there a better alternative for this task?
Edit:
Yes, I need to print this to a Printer device.
The table is fairly simple, this is an example of it.
Table to output example
I am preparing to embark on a large solo project at my place of employment. First let me describe the project. I have been asked to create a Java program that can take a CamT54 file (which is just a xml file) and have java display the information in table form. Then users should be given the ability to remove certain components from the table and have it go back to xml format with the changes.
I'm not well versed in dealing with XML in Java so this is going to be a learn and work task. Before I begin investing time I would like to know that my approach is the best approach.
My plan is to use DOM4J to do the parsing and handling of the xml. I will use a JTable to display the data and incorporate some buttons to the GUI that allow the modifications of the data through the use of some action listeners.
Would this be a plausible plan? Can DOM4J effectively allow xml data to be displayed in a table format and furthermore could that data be easily modified or deleted then resaved to a new xml?
I thought I would go ahead and answer this as I finished the program and wanted to post what I thought was the easiest solution in case anyone else needed help.
It turned out the easiest approach (for me at least) was to use the standard DOM parser, here are the steps I took.
Parsed the entire XML into String array lists. XPath was required for this, I also had to convert the elements into Strings and remove the extra tag information from the string using substrings since I only wanted the actual value.
I populated a JTable with these arrays.
Once users finished editing and clicked a save button then another Dom parser would take the original XML and change each and every attribute using the values from the Arrays (that were deleted and repopulated with the JTable cell values when the user clicked "save").
I am providing the scenario as an image, which I guess would help in better understandability.
Here I have to pass object from different Swing forms and accumulate it to create a new document which will consist the concatenated texts, tables etc.
My question, is it possible to do the same.
N.B :- I am able to do simple tasks in iText - reading tables from Swing forms, etc.
Thanks, suggestions are very much appreciated.
Yes it is possible to do the same with itext. May be you can do it this way
Create document
Get Form 1 Values. Create a Chunk using the Form 1 Text.
Add the Chunk into the Document
Get Form 2 Values. Create a Chunk using Form 2 text
Add the Chunk into the Document
Like this do for all the forms.
The above is solution for adding all the text from different forms into document.
Refer Link for itext references.
If in case all the texts has to concatenated do it well ahead and add it to the Chunk.
P.S: Am not familiar with Swing framework.
I have the following scenario, and need some advice:
The user will input a word document as a template, and provide some parameters in runtime so i can query my database and get data to fill the document.
So, there are two basic things i need to do:
Replace every key in the document with it´s respective result from the current query line.
"Merge" (copy? duplicate?) the existing document unchanged into itself (append) depending on how many rows i got from the query, and replacing the keys from this new copy with the next row values.
What´s is the best aprroach to do this? I´ve managed to do the replace part for now, by using the unmarshallfromtemplate providing it a hashmap.
But this way is a little bit tricky, because i need to add "${variable_name}" in the document, and sometimes word separates "${" and "}" in different tags, causing issues.
I´ve read about the custom xml binding, but didn´t understand it completely. I need to generate a custom XML, inject it in the document (all of this un runtime) and call the applybindings?? If this is true, how would i bind the fields in the document to the xml ? By name?
docx4j includes VariablePrepare, which can tidy up your input docx so that your keys are not split across separate runs.
But, you would still be better off switching to content control data binding, particularly if you have repeated data (think for example of line items in an invoice). Disclosure: I champion this approach in docx4j.
To adopt the content control data binding approach:
dream up an XML format which makes sense for your data, and write some code to convert the results of your database query into that format.
modify your template, so that the content controls are bound to elements in your XML document. ordinarily you'd use an authoring add-in for Word to help with this. (The technology Microsoft uses for binding is XPath, so how you bind depends on your XML structure, but, yes, you'd typically bind to the element name or ID).
now you have your XML file and a suitable intput docx, ContentControlsMergeXML contains the code you need to create an instance document at run time. There's also a version of this for a servlet environment at https://github.com/plutext/OpenDoPE-WAR
As an alternative to 1 & 2, there is also org.docx4j.model.datastorage.migration.FromVariableReplacement in current nightlies, which can convert your existing "${" document. Only to a standardised target XML format though.
