Re: definitive answer on JSPC?
Don't know how 'definitive' this is, but here are my experiences. Its a bug/feature of jspc, depending on how you look at it. As it loads all relevant jsp files into memory to compile, it only used the file name, not the full path, making the compiler see all your index.jsps as the same, which causes the error. I believe there is a fix for this out there somewhere. I found a pointer to the fix on an Ant message board. I also added functionality to Ant that compiles each jsp in its own memory space, thus working around the bug. Let me know if you can't find the fix (it might already be part of the next Tomcat build) and want to dork around with my effort. The work I did on it was back about 3 months ago, so I don't know what has been done recently.

Searching the archives hasn't yielded answers to the questions I've been curious about. It'd be great to get definitive answers for the archive, and perhaps a FAQ as it is not covered in either tomcat-user, the doco, or JGuru. Background: In TC3.2.4 I currently precompile all JSPs using the ant jspc task and the TC3.2 jasper/webserver jars. I then munged the generated java files into the format required by TC3.2.4 and compiled them, then renamed them again to match. A little weird, but it worked since it used a flat directory structure, formatting the filenames with_002f etc. I dropped this into /WEB-INF/classes/precompiled_jsp and symlinked it from work/localhost_8080%2Fapps. The reason this was necessary was that the server choked under the load trying to compile the JSPs. There seemed to be no deadlocking so it would spawn numerous javacs and start swapping, and you get the picture :) With TC4.1 I can't take this approach because of the (albeit nicer) directory approach. However, because of duplicate names and the same package being used, I will need to compile each java file individually, complicating the build process considerably. BTW, I'm aware of ?jsp_precompile=1 and it's not suitable. Here are my questions regarding jspc from ant/cmd line: 1) is the definitive way to do it supposed to be the web.xml include method? If so, shouldn't JSP take a web.xml input and output a processed one? Regardless, doesn't this have negative side effects, like not then being able to edit the JSPs to make changes? (note that while we precompile, we may need to change some, and filtering them out would be a fair nuisance). 2) is there a way to do what I am looking for above, generating classes for all JSPs that are not fragments (for static include) which can be placed in the work dir? Does it have to have the same layout as the server to work? 3) what is the reason for the current layout and differences between cmd line and server compilation? ie. different dirs but same package. My desired requirements for JSPC to work would be: 1) both JSPC and server generate the same java files to the same locations. 2) javac can be executed on the base directory on **/*.java, and the resulting classes dropped into the work directory. They would be used as long as their timestamps were newer than the jsp in question. To achieve this, I'd suggest this: 1) package name is org.apache.jsp.PATH.TO.FILE (substituting/eliminating special characters - eg WEB-INF - WEBINF) 2) class remains myJsp_jsp.java 3) have TC not only look under work but /WEB-INF/classes to avoid the symlink (ie if I specified my package as precompiled_jsp I'd get the result as I have for 3.2.4). And a final question: how likely am I to encounter the problems had with 3.2.4 if I upgrade to 4.1? I believe the jasper2 compiler is designed to be much more effecient - will it avoid generating the java files more than once and hence compiling them more than once, instead synchronizing on the operation? (this is effectively enough, although precompilation would still be even faster). I'd appreciate any responses regarding this, and apologise for the verbosity level of the email! :) Thanks, Brett - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Tomcat 3.2.2 and Xerces
Sorry. Asleep at the wheel. I didn't see this earlier. The problem is that Tomcat uses a different xml parser than xerces and there is a version conflict of some sort that I knew back when I had the problem but have since forgotten. To fix, the easiest way is to modify the tomcat.bat or tomcat.sh file in the way the CLASSPATH is created. Simply put your CLASSPATH defs before the ones that are added by the script. There should be a line like this CP = CP + CLASSPATH just flip it around CP = CLASSPATH + CP excuse the non-standard syntax, but hopefully you get the idea. This lets xerces be found first and the world is good.

Nope. I removed it entirely and still got the 404. Also, that invoker is still in my server.xml file on my localhost and it works fine.

RE: Servlets and relative paths
No, my problem is that I can use this method to read the xsl file just fine. It's the includes inside the xsl file that aren't working. For example, inside the xsl file (which I read into the servlet using your pointer from the earlier email) there is the line xsl:include href='sections.xsl'/ and I get an error saying that it cannot find file tomcat/bin/sections.xsl. Which, of course, it cannot, since the file is located in Meta-Inf/.

This is certainly a step in the right direction. I can now include the xml file and xsl file using relative paths. My only problem now is that there are xsl includes inside the xsl files and they are still being loaded incorrectly (using the tomcat/bin directory as root, not the servlet context). Any ideas?

MyUtil myobject=new MyUtil(); InputStream is = myobject.getClass().getResourceAsStream(testApp.properties); ... I don't test it, if it is not right, please correct it, thanks! :-) Bo May.30, 2001
RE: xalan ApplyXSL sample servlet fails
Funny you should ask. I had (possibly) a very similar problem last week. After combing through maillists etc, I found a reference suggesting that there was a conflict with the xerces xml parser and the xml parser included with tomcat. It suggested removing parser.jar and jaxp.jar from the classpath in the tomcat startup scripts (tomcat.bat for me). That worked for me. I've only been playing with it for a day or two, but it doesn't seem to break tomcat and now my xalan-based servlets function. Chris -Original Message- From: Stan Devitt [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 29, 2001 8:35 AM To: [EMAIL PROTECTED] Subject: xalan ApplyXSL sample servlet fails Any pointers to additional info, a working example, or direct help in resolving the following would be most appreciated. Stan Devitt == I am attempting to run the servlet example that is part of the xalan1.2.2 zip file - specifically with DefaultApplyXSL, whose purpose is to apply xslt transformations. I am using tomcat 3.2.1. (more details below) I have installed the servlet in a Test context and a sample xml and style file tested independently. I successfully link to the servlet using: http://localhost:8080/Test/servlet/DefaultApplyXSL? debug=trueURL=/Test/main.xmlxslURL=/Test/styles/main.xsl but the transformation fails in the process method in ApplyXSL during xslprocessor.process(xmlSource, xslSource, outBuffer); The debug response indicates that a) it is finding the servlet, b) it is finding the xml file and its style file, however, a SAX exception occurs while it is being processed to generate html output - the log shows SystemId Unknown; Line 1; Column 1; SystemId Unknown; Line 0; Column 0; Exception is org.xml.sax.SAX Exception Additional Notes: 1. The xml and style file has been validated and successfully transformed using both xt and xalan in command line mode. 2. I am using tomcat 3.2.1, together with jdk1.3.1, xerces 1.2.3 and xalan 1.2.2 on Windows 2000. 3. There is no DOCTYPE in the xml file, nor is there a style sheet processing instruction. 4. The xalan.jar and xerces.jar files are at the start of the class path. Thanks in advance.
mod_jk and mod_rewrite? Do they work together?
Does anyone have an answer to this question? I'm attempting to map my root web directory to a particular jsp page. For example, I would like the URL www.byteme.com to resolve to www.byteme.com/context1/jsp/index.jsp Any ideas? Thanks, Chris
