Unable to compile class for JSP

[pisth]

Hell0 All,
I am trying to create an application in JSP which inturn calls a java file.

However when i execute the JSP page(using Tomcat webserver) i am getting an error which says...

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: -1 in the jsp file: null
Generated servlet error:
[javac] Since fork is true, ignoring compiler setting.
[javac] Compiling 1 source file
[javac] Since fork is true, ignoring compiler setting

I think the following line in the JSP page is the one which causes the problem:

<jsp:useBean id=&quot;MATRIX&quot; scope=&quot;page&quot; class=&quot;MatrixBlast.MatrixBlastC&quot; />

MatrixBlastC is the name of the java file/class i am having.

if i take this line off in the jsp file...i get an o/p page...however i need to call the java file too for the program to work.

Kindly suggest how do i resolve this issue.

Thanks!

Regards,
Karthik.

Check that the package that you are referencing is jarred up in the WEB-INF/lib dir, or unjarred in the WEB-INF/classes dir.

Also try changing your scope from &quot;page&quot; to &quot;session&quot; - just to test !

Hell0 sedj,
Thanks for your e-mail.

I tried changing the line to &quot;session&quot; instead of &quot;page&quot;
I still get the same error.

Check that the package that you are referencing is jarred up in the WEB-INF/lib dir, or unjarred in the WEB-INF/classes dir

what do i need to do to check the package?. i dont have alib direcotry under web-inf...or classes under web-inf.?

Can you kindly explain...i have the lib directory in differen tfolders...not here...do i need to copy the class files n paste it somewhere?

Thanks!

Regards,
Karthik.

When you use your own classes or packages in tomcat you need to put them into a jar file and then into WEB-INF\lib, or put them (unjarred) into WEB-INF\classes.

So, if you don't have a classes directory under WEB-INF - then make one. Then compile your MatrixBlast.MatrixBlastC class, and put it into the classes dir. So your class MatrixBlastC should be sitting in a directory structure as follows - WEB-INF\classes\MatrixBlast.

If they were not in a package then they could just sit in the classes directory.

Karthik,

I see you're still not reading the documentation: thread695-546146

Makes being a programmer kind of rough eh?
