Hi, I am new to this list, so let me quickly introduce myself: I am Felix Meschberger and am working on a Web Content Management Application running on a Java Content Repository (Apache Jackrabbit) provding amongst other things dynamic compilation of JSP scripts. I am also a committer to the Jackrabbit project to which I contributed the JCR ClassLoader and worked on the RMI layer library.
Integrating JSP support in the application is the reason for me be here: To compile JSP, I took Jasper 5.5.20 and adapted it to my use case, which I will explain quickly. As I said, the application will run on Jackrabbit. Consequently, JSP source will be stored in the repository not the OS Filesystem or the Web App Context. Also, generated Java Source and Servlet classes will be stored in the repository. The repository class loader will pick the servlets up for execution. To enable this functionality, I patched Jasper as follows: * Defined a new IOProvider interface, which abstracts the File operations: getInputStream, getOutputStream, mkdirs, delete and some more. Of course a default file based variant has also been implemented * Fixed all direct File uses to use the new IOProvider API * The IOProvider is set on JspRuntimeContext and defaults to the File-based implementation * Modified JspCompilationContext.loader field to be a class loader, as my environment has no URLClassLoader * To inject my custom class loader, I added API to the Options interface to return a custom provided classloader to compile (in the case of Eclipse Compiler) and load JspServlets instead of the JspLoader. * Another change to the Options interface: the getScratchDir method returns a File, which is not available in my environment. In fact the scratchDir suffices it to be a String, which may be interpreted as a Filesystem directory in the standartd use case. Hence, I modified the method to return a String (Yes, I know, this is a "dangerous" modification !) I would like to to know, whether you would be interested to see these patches and might consider them for addition to the Jasper code ?
