This may be similiar or the same as 17719.

The Tomcat output windows shows the line used to start Tomcat. When Tomcat 
startup hangs, it is caused by an extra quote in the classpath. I've been 
getting this intermittently, and now it looks like constantly.

This is a cut and paste from the output window. Note the extra quote in the -cp 
which is never closed (and shouldn't be there?). The subsequent directory name 
has spaces, which may be causing the quote to be inserted.

C:\JDK13~1.1_0\jre\bin\java  -cp "C:\netbeans\modules\jsp-
tomcat.jar;C:\netbeans\modules\jsp.jar;C:\netbeans\modules\ext\jasper.jar;C:\net
beans\modules\ext\webserver.jar;;C:\netbeans\lib\ext\xerces.jar;;"C:\Documents

Documents\TeamForecast\Source Code\Server 
Source\system\tomcat\server.xml" "C:\Documents and Settings\ng\My 
Documents\TeamForecast\Source Code\Server Source\system\tomcat"

I suspect the problem lies in TomcatServerExecution.getSortedFileSystemNames,

which I have excerpted below:

      StringBuffer sb = new StringBuffer();
        sb.append(getTomcatClasspath(pathSeparator));
        Enumeration e = FileSystemCapability.EXECUTE.fileSystems();
        if (e.hasMoreElements()) {
            sb.append("\"");

I suspect (but have not proven) that sb.append("\"") may be the offender.

I also note from TomcatServerExecution.getTomcatClasspath that "parser.jar" 
and "servletjar" have not been added to my classpath, which seems like it might 
be bad. You will note the ;; in the classpath above where they are missing. The 
following excerpt from TomcatServerExecution.getTomcatClasspath shows where 
that portion of the classpath is built.       

            buf.append(jsp_tomcat).append(ps);
            if (dd2beans.length ()>0) 
                buf.append(dd2beans).append(ps);
            buf.append(jsp).append(ps);
            buf.append(jasper).append(ps);
            buf.append(webserver).append(ps);
            buf.append(parser).append(ps);
            buf.append(xerces).append(ps).
                append(servletjar).append(ps);

Unlike dd2beans, the others are not checked for non-existence before appending.
