Java Forum / General / May 2005JSP says "Cannot find class" but the class is there!
Hello, I'm using WebLogic 5.1 sp12 on Solaris and when i try and compile a JSP page I get the error /tmp/support/jsp_servlet/_www/__listCurriculum.java:75: Class cms.logic.Curriculum not found. However, I have verified that the file "cms/logic/Curriculum.class" exists and that "cms" is in the classpath. The whole thing is in a jar file and the jar file itself is in the classpath. One thing I have noticied, however, is that there are other jar files in the classpath that contain files like vendorA/cms/dir/VendorClass1.class vendorB/cms/dir2/VendorClass2.class Is the fact that "cms" is referenced at a sub-directory throwing things off?

You need the directory ABOVE cms to be in the classpath. For example, say I have a package foo sitting in /home/kaeli/bar. i.e. /home/kaeli/bar/foo/doit.class If I want to use that stuff, /home/kaeli/bar needs to be in the classpath, not /home/kaeli/bar/foo. > vendorB/cms/dir2/VendorClass2.class > > Is the fact that "cms" is referenced at a sub-directory throwing things > off? No.  Signature-- ~kaeli~ I love God. It's His fanclub that I can't stand. http://www.ipwebdesign.net/wildAtHeart http://www.ipwebdesign.net/kaelisSpace Thanks for your reply. As it happens /home/kaeli/bar/ (or the equivalent in my example) is in fact in the classpath and not /home/kaeli/bar/foo. What other possible reasons are there for this problem, however obscure those reasons may be? - Dave > Thanks for your reply.

If WebLogic can be trusted to be providing the correct error message (i.e. for the rootmost cause) then it is a classpath-related error -- that's what it _means_ that the class cannot be found. Before you go much further, however, you should be sure *which* classpath you're talking about, as there may be more than one depending on how you compile the JSP. It looks like you're letting the JSP engine autocompile it, which should be fine. In that case you should have a jar in the webapp's WEB-INF/lib directory, and in that jar you should have an entry named exactly "cms/logic/Curriculum.class" that contains the bytecode for class cms.logic.Curriculum.class. There may also be other files in the same jar, of course. SignatureJohn Bollinger jobollin@indiana.edu > Thanks for your reply.

What other possible reasons are there for this > problem, however obscure those reasons may be? The invoking code in the JSP and a stack trace would help. Some random thoughts... Whose classpath? Yours, or the web server? It has to be the server's (weblogic's) classpath, not the normal environment classpath. Did you check case-sensitivity? Caller and class and directory must all match case. Unlikely, but see if you can tell what exactly is the process doing the compile and check how (i.e. whence javac and javac -version, but for the processes, not your login). Could be a JVM version issue where one process is using one version and the other, another. For example, the compiler to take the JSP into java uses /usr/bin/java1.2 and the one that compiles java to class uses /usr/local/bin/java1.4.

I don't know about Weblogic, but the Tomcat server pays no attention to the environment CLASSPATH - perhaps Weblogic also has its own rules for finding classes and ignores CLASSPATH settings.
