Jasper2's JspC
Hi, I'm having partial luck manually invoking JspC and compiling JSP pages on demand. I get as far as precomiling to .java, but for the world of me can't figure out how to get the java class compiled to bytecode. Looking at the source code for org.apache.jasper.compiler.Compiler, it appears that I should be getting a .class as well, but I'm not. Can anyone offer any pointers or sample source code I could look at (reminder, this is for Japser2)?

Use the -compile argument. -Original Message- From: Dmitry Beransky [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 9:55 AM To: [EMAIL PROTECTED] Subject: Jasper2's JspC Hi, I'm having partial luck manually invoking JspC and compiling JSP pages on demand.

RE: Jasper2's JspC
Try using jspc with the -compile flag and see what happens. Your code is probably not setting something (I don't know what), which is causing it to not compile. As an aside, I don't use the -compile flag to compile. I use the jspc script to create the .java files and then I use Jikes to compile. It's much much faster than javac.

I'm already making this call (I'm actually bypassing JspC, setting all the options and contexts myself and calling Compiler.compile() directly). Compiler.compile() makes a call to generateClass() which in turn invokes Ant's javac task to compile the file. The task completes with no errors or exceptions; I'm stepping through the execution in a debugger and I can see that 'success' flag is set to true upon the javac's completion. Yet there is no .class file to be found anywhere. Dmitry -Original Message- I'm having partial luck manually invoking JspC and compiling JSP pages on demand.

Your code is probably not setting something (I don't know what), which is causing it to not compile. You're right. I found a conflict in option settings between the output directory and the jsp file name. The sample jsp I'm trying to compile is located in /layouts/default.jsp, the webapp root api is set to c:/projects/cms/web and the output directory is set to c:/temp. When the jsp file gets precompiled with these settings, the resulting .java file gets dumped into c:/temp/default_jsp.java, but when the compiler is getting invoked, it's looking for the file in c:/temp/layouts/. I'm going to comb through JavaC code to see what exactly it is that I'm missing. Thanks Dmitry - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
