Tomcat's JSP Engine and tomcat JSP Engine The jasper component of tomcat must be used to parse jsp files into class files.Jasper is the JSP Engine Used in tomcat, and Jasper 2 is used in Tomcat 6. Compared with the original version, Jasper has made many improvements, such: JSP Tag Buffer Pool, background compilation, automatic re-compilation during page change,

The detailed introduction of JSP automatic compiling mechanism In general, the Jasper Automatic detection mechanism is relatively simple, relying on a background thread to constantly detect the JSP file and the compiled class file after the final modification time is the same, if the same is not changed, but if different will need to recompile. In fact, because the JSP for the project deployed in Tomcat may have introduced other pages, or other jar p

, and if there are no errors, you can use the report template in your program. JasperReports Introduction: Using JasperReports to generate reports is very simple, using only a few classes in the Net.sf.jasperreports.engine package to complete the report generation, preview, print, export and other functions. 1. Net.sf.jasperreports.engine.JasperCompileManager class. Use several static methods of this class to complete the compilation of the report (see API documentation specifically) There

Existing Java open-source Bi front-end framework I recently demonstrated the open-source Bi front-end framework in the Java field and shared some things I remember.Because I only watched it for a few days and didn't have time to sort it out, it looks messy and not very thorough. Currently, common bi front-end frameworks (Business Intelligence projects) in the Java field mainly include the following open-source frameworks such as pentaho, spagobi, openi, and
