Use the jasperreports report to generate a pdf document that cannot display Chinese characters. How can this problem be solved? jasperreportspdf
In the jrxml and jasper files generated using the jasperreports5.6.0 series of development tools, the jar packages related to fonts in pdf are as follows:
IText-2.1.7.js2.jar; iTextAsian. jar.
When designing a jrxml file, pay attention to setting the attribute values of elements (such as Text Field and Sta

Because the struts2-jasperreports-plugin-2.3.14.jar plug-in corresponds to the jasperreports-3.1.2.jar version, if you use a higher version of jasperreports or ireport tool to generate a file in the jasper format, here there will be some conflict. The sample code related to this method is not provided.

3. External Printing
Strictly speaking, this cannot be printed. It is actually a data export solution. It imports application data to an external tool and then uses this tool for printing. There are several common types:
1) PDF printing: PDF is an industry standard. pdf Development kits (such as Java-based itext and flex-based alivepdf) can be used to form PDF documents for application data, it is then printed by Adobe Reader or other tools.

Java converts an excel file into a PDF file
Recently, when I was working on a project, I needed to convert the excel file into a PDF file. After I checked the information, I used only two methods: 1 POI + Itext 2 Jacob to call the excel save function.
The first method is to use POI to read the excel content and write it to a PDF file. The implementation is a little difficult, mainly because the excel sheet structure is not fixed, the content is not f

This method is similar to using the browser function, and directly performs the content of a URL address. Compared with the previous two methods: first, html content rendering for rich texts is more convenient and simple, and html code can be directly generated. second, content layout is more reasonable, there will be no blank areas in the pdf document. third, the Chinese support is more friendly.

Sample code:

Disadvantages:
Using unreliable COM interop to handle the IFilter interface (and combining IFilter com, Adobe PDF IFilter is particularly troublesome).
Adobe IFilter needs to be installed separately on the target system. If you need to publish an indexed solution to someone else, it can be painful.
