Compiling JSP files with Org.apache.jasper.JspC--reprint

The JSPC can be Jspc.setargs (args), set the required parameters, and compile the same with the instructions.

Use the instructions to compile the example:

JAVA-CP Jasper.jar;servlet-api.jar; Fcatalina.jar; F:\server\tomcat.6\bin\tomcat-juli.jar;ant.jar;jsp-api.jar;jasper-el.jar;el-api.jar;jstl.jar;standard.jar; Jasper-el.jar;jasper-jdt.jar org.apache.jasper.jspc-uriroot./temp-d temp temp.jsp

You can also set parameters by calling the Set method

Java code

2. Public class Test1 {
4. Public String Jspctest () {
6. String error="";
8. try {
10. JSPC JSPC = new JSPC ();
12. /*string[] arg0 = {"-uriroot", "E:/JSPC", "-D", "d:/t",
14. "Temp/temp.jsp"};
16. Jspc.setargs (ARG0); * *
18. Jspc.seturiroot ("D:/JSPC"); Web app's root directory
20. Jspc.setoutputdir ("d:/t"); Output directories for. java files and. class Files
22. Jspc.setjspfiles ("temp/temp.jsp"); The JSP to be compiled
24. Jspc.setcompile (true); Whether to compile false or not specify only the. java file is generated
26. Jspc.execute ();
28. } catch (Exception e) {
30. Error=e.tostring ();
32. }
34. return error;
36. }
38. public static void Main (String args[]) {
40. Test1 t=New Test1 ();
42. System.out.println (T.jspctest ());
44. }
46. }

Here the jar packages are referenced from Tomcat

The test class compiles the necessary jar packages:

D:/tomcat5.5/common/lib/jasper-compiler.jar

D:/tomcat5.5/common/lib/jasper-runtime.jar

JSP compiles the necessary jar packages, in addition to the jar that references the class in the JSP:

D:/tomcat5.5/common/lib/commons-el.jar
D:/tomcat5.5/common/lib/jasper-compiler.jar
D:/tomcat5.5/bin/commons-logging-api-1.1.1.jar
D:/tomcat5.5/common/lib/jsp-api.jar
D:/tomcat5.5/common/lib/jasper-compiler-jdt.jar
D:/tomcat5.5/common/lib/servlet-api.jar
D:/tomcat5.5/common/lib/jasper-runtime.jar
D:/tomcat5.5/server/lib/catalina-ant.jar

If you are running the engineering environment in a Tomcat Web environment, add the ant jar to
