Unable to build jasper-compiler.jar for Tomcat 5.5
Could someone point me to directions on how to build jasper-compiler.jar? This is the first time I've tried to build Tomcat, and while the build for Tomcat appeared to go well (there are many jars, but there were errors in getting eclipse files from http://sunsite.informatik.rwth-aachen.de/eclipse/downloads/ so that part of the build failed), there was no build for the jasper-compiler.jar. I would like to build j-c.jar to add extra debugging information to DefaultErrorHandler.java. I got the source distribution for Tomcat 5.5.12, because that is the version we are running. There is source for jasper-compiler.jar, but no jasper-compiler.jar. When I try to run the ant build in the Jasper2 directory, following the BUILDING.txt instructions in that directory, it doesn't work with the following errors: -- E:\apache-tomcat-5.5.12-src\jakarta-tomcat-jasper\jasper2>ant -v jsp20el.dist Apache Ant version 1.7.0 compiled on December 13 2006 Buildfile: build.xml Detected Java version: 1.5 in: C:\Program Files\Java\jdk1.5.0_04\jre Detected OS: Windows 2000 parsing buildfile E:\apache-tomcat-5.5.12-src\jakarta-tomcat-jasper\jasper2\buil d.xml with URI = file:/E:/apache-tomcat-5.5.12-src/jakarta-tomcat-jasper/jasper2 /build.xml Project base dir set to: E:\apache-tomcat-5.5.12-src\jakarta-tomcat-jasper\jaspe r2 [antlib:org.apache.tools.ant] Could not load definitions from resource org/apach e/tools/ant/antlib.xml.

Building the Jasper compiler
Could I ask again for a reference to instructions on how to build the Jasper compiler? The Building.txt that comes with it does not work for me (Win2K, jdk 1.5, ant 1.7.0). Or, would you let me know if it is not possible to build the Jasper compiler except through the Tomcat build? I have been able to compile individual classes in jasper, so that's what I've been doing, and patching the working jar I have. But I'd rather be following an ant build process, just to be sure that all of the environment is being referenced correctly. Is there a mailing list just for Jasper that I should be sending this question to? M Coffee We won't tell. Get more on shows you hate to love (and love to hate): Yahoo!

Re: Building the Jasper compiler
William, Thanks for responding. This explains why I couldn't find an independent build process for Jasper. So I'll continue patching the jar, and wait for the development you do on Gentoo. If you do any work on the Jasper compiler, please think about addressing the problem of getting reasonably good source code lines numbers (jsp or java would be fine) from a JSP compile error. It worked well in Tomcat 4, but the Jasper compiler in Tomcat 5 does a poor job of it. That's why we haven't switched our development environments to Tomcat 5, and why I'm trying to do some sort of hack to at least see the underlying compiler error messages. M Coffee --- "William L.

There is a jasper build.xml, but it doesn't build the jars without a complete Tomcat build environment (and possibly an older version of Ant), so I stopped working on debugging that one. There's no documentation for it either -- the code is the documentation, I guess. I definitely don't want to move up to Tomcat 6 until the problems with debugging JSP pages in the Tomcat 5 environment are resolved. We've waited a while, and now I'm trying to hack it to the point where we can use it internally. Thanks again, M Coffee > -- > William L. Thomson Jr. > Gentoo/Java > Finding fabulous fares is fun.

JSP Compiler error messages lower quality in Tomcat 5.5?
The quality of the JSP compiler error messages for Tomcat 5 seems much worse than those for Tomcat 4. The difference makes debugging much harder under the Tomcat 5.5 releases. Is there a way to build Tomcat with different components to have it provide better compiler error messages? As an example, this JSP code snippet: errMsg = "Uploaded file has no readable records or is empty."); generates this compiler error message in Tomcat 5.5.12: SEVERE: Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: Unable to compile class for JSP An error occurred at line: 7 in the jsp file: /adminArea/UploadFile.jsp Generated servlet error: Syntax error on token ")", delete this token However, the same file under Tomcat 4.1.24 generates this compiler error message: --- Generated servlet error: [javac] Since fork is true, ignoring compiler setting. [javac] Compiling 1 source file [javac] Since fork is true, ignoring compiler setting. [javac] D:\jakarta-tomcat-4.1.24\work\Standalone\localhost\_\adminArea\UploadFile_jsp.java:1998: ';' expected [javac] errMsg = "Uploaded file has no readable records or is empty."); [javac] ^ [javac] 1 error ------ M Coffee __ Do You Yahoo!?

Re: JSP Compiler error messages lower quality in Tomcat 5.5?
Yoav -- thanks for this link. The patch you referenced installs and runs, but doesn't solve the problem Tomcat 5 has with showing where the JSP compiler error occurred. We installed the patch on a Tomcat 5.5.12 instance, and it runs successfully, but the output for the same code snippet is still uninformative: -- org.apache.jasper.JasperException: Unable to compile class for JSP An error occurred at line: 7 in the jsp file: /adminArea/UploadFile.jsp Generated servlet error: Syntax error on token ")", delete this token org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:474) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:372) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) root cause org.apache.jasper.JasperException: Unable to compile class for JSP An error occurred at line: 7 in the jsp file: /adminArea/UploadFile.jsp Generated servlet error: Syntax error on token ")", delete this token org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:84) org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:328) org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:409) org.apache.jasper.compiler.Compiler.compile(Compiler.java:288) org.apache.jasper.compiler.Compiler.compile(Compiler.java:267) org.apache.jasper.compiler.Compiler.compile(Compiler.java:255) org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:563) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:300) - In reading the Bugzilla reference you included, I see that there are more layers of indirection between the compiler and the Tomcat output -- with even more added in later releases of Tomcat 5.5 -- so that is probably the issue: someone didn't propagate the full compiler error information up the stack. Has anyone looked at this, or can someone point me at the likely spot to collect the correct information from the JSP compiler so that I could start trying to build a patch?
