Generated Java files using Jasper has incorrect names...
I used JASPER 2 which includes with TOMCAT (6.0.20), to pre compile some of my JSP files, but there is a problem with file names which are pre compiled by Jasper. If there is a underscore on JSP files then Jasper will generate Java files with incorrect names. e.g. compiled JSP file - get_BreadCrumbs.jsp pre compiled Java file - get_005fBreadCrumbs_jsp.java as you can see name has some unnecessary 005f tag on the name. How to prevent this, any idea -- _A_N_I_M_E_-_O_T_A_K_U_

I'll try trace and see if it can provide more information there (I didn't realize trace had more information then debug). Trace adds log lines for entering and leaving functions (not so interesting for you) but also switches from logging only the first couple of bytes in each raw AJP packet to dumping the full packet contents to the log file. It is a raw packet dump though, but since the cookie headers are strings, they can be recognized in the packet dump relatively easily. Try with a request which does send the cookie first, so you know what to look after.

So, I was trying to generate some content using Javascript yet pass-in
all the elements of the URL to the javascript so I wouldn't have to
either hard-code context paths into the Javascript or use a dynamic
javascript source.
Anyhow, I had done something like this:
function foo(..., contextPath, ...) {
}
foo(..., '%= response.encodeURL(request.getContextPath()) %', ...)
That, of course, gives me a contextPath that looks like
/context/;jsessionid= and then appending paths onto it breaks
everything.
So, I now have split things up like this:
function foo(..., contextPath, pathSuffix, ...) {
...
// build a URL
var url = contextPath + '/images/help_widget.gif' + pathSuffix;
...
}
... and passing request.getContextPath() as the first argument and then
passing response.encodeURL(.).substring(1) as the second argument. A
bit of a hack, but it'll work.
Thanks for not making fun of me too much.

However if I copy the JSP into the js folder (and remove the js from the src=) then it works! Why can the JSP see the js folder? As others have said, it's the browser which either sees or doesn't see something. If you're using Firefox, you could use one of the many extensions to find out what the browser actually requests, and what is the request from the server. My preferred FF extension for this would be TamperData. If you have access log enabled on your server, the requested resource path along with the HTTP response code set by the server will also be visible there. Remember that the browsers always request with absolute paths; relative paths are an HTML feature, but requests are done with HTTP, which only recognizes absolute paths. Thus, the browser will create the absolute paths based on location of the referring resource and the relative reference. As always with relative references, you have to pay close attention to the context. -- ..Juha - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: [OT] ms sql integrated auth woes

By the way, I've never seen win\sys32 as a meaningful path.

Where is your mssql.jar file located? i saw a thread dealing with native libs or dll's can only be loaded once or such Correct, native libraries can only be loaded once. If you have a Java library that loads a native library, you just need to make sure that the Java library is only initialized once. If you are using Tomcat in the typical way, you should have a JNDI Resource configured for a JDBC connection pool, and your mssql.jar file will be in %CATALINA_HOME%\lib. In this setup, your JDBC driver should only be initialized once, and therefore the native library should only be loaded once. Can you stop Tomcat, delete all log files, start it up, use a connection, redeploy your webapp, try to use a connection again, then shut down Tomcat, then post the catalina.out file that gets produced from having done all that?
