RE: Compile JSP with Tomcat/IBM JDK 1.2.2/AIX4.3.3
I wrote a class around the javac from IBM,... Is this javac from IBM freely redistributable? I believe the javac that comes with Sun's JDK is not. That is the main reason for substituting javac with Jikes for many of us. I don't quitte get that question, as everyone is able to download sun's jdk from their site isn't it?? That's the same for the IBM jdk, with the only difference that you have to register yourself before you can download it. And, if you do not plan to redistribute your application, why not use tools.jar? You mean, the sun's javac compiler in the tools.jar? Mm... didn't thought about that option. Also, do you plan to post your solution in how to - step by step form so that users who encounter the same problem on AIX would benefit? 1. Copy JikesJavaCompiler.java from the Tomcat sources to IBMJavaCompiler.java 2. Remove the packagename from the top of the file, or insert a new package statement. 3. Add the -O option to the commandline String[] in compile() (to 'optimize' compilation) 3. Compile your class put it in a jar (jar -cvf ) 4. Put the jar file in the tomcat/lib directory 5. Add jspCompilerPlugin parameter to web.xml and specify your classname (IBMJavaCompiler) 6. Add jspCompilerPath parameter to web.xml and specify the executable of the compiler ($IBMJDK_HOME/sh/javac) 7. Flush work directory 8. Start tomcat 9. Your jsp's are being compiled with ibm's compiler. If not, check logs/jasper.log for initialization errors for your compiler. That's it. Rgrds, Klaas
RE: Compile JSP with Tomcat/IBM JDK 1.2.2/AIX4.3.3
Hi, I did not mean Jikes because I already have a javac (which comes with the JDK), and I don't want to compile Jikes from source for the AIX platform. But your directions pointed me in the right way: I wrote a class around the javac from IBM, basically it's a copy of JikesJavaCompiler, but with some modified command line parameters. I added this class to my WAR, and modified application/web-inf/web.xml and added jspCompilerPlugin and jspCompilerPath. And that works fine. So, basically thanks for your suggestions, but I did it a bit different. (And at least easier for AIX) Rgrds, Klaas -Original Message- From: Gautam Sinha [mailto:[EMAIL PROTECTED]] Sent: donderdag 2 augustus 2001 16:11 To: [EMAIL PROTECTED] Subject: RE: Compile JSP with Tomcat/IBM JDK 1.2.2/AIX4.3.3 I assume you mean the Jikes compiler when you say IBM's javac compiler.

But, when I request a jsp page, I get an exception sun.tools.javac.Main etc Of course, this is related to the fact that I'm not using sun's jdk.

I don't know about using the javac from IBM, but you may want to try using Jikes with Tomcat. There is some info at http://www.jguru.com/faq/view.jsp?EID=307643 but read the comments, because the answer is out of date for Tomcat 3.2, which no longer reads TOMCAT_HOME/conf/web.xml.
