Tomcat Class Loader Delegation

In tomcat loader, i just want to make changes that classloader loading priority is: patch lib folder, web-app lib folder, common lib loader, system lib loader, bootstrap lib loader (so we'll effectively have the patch lib loader with a higher priority than the web app lib folder). The patch lib is where i place my patches with classes which needs to override the classes in the WAR at run time.



This should work for any Tomcat web application (war file/folder), regardless of how it's created or stored (expanded war file, folder, etc).



the class loader should search for the patch jar files hosted in the J2EE property patch.shared.loader residing in the files patch.properties, available in the J2EE server path ($ {catalina.base}.



How can this be achieved without using a Java Typical Class loaders?



Thanks in advance.

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...

          Calculate evaluation metrics using cross_val_predict sklearn

          Image
          1 In the sklearn.model_selection.cross_val_predict page it is stated: Generate cross-validated estimates for each input data point. It is not appropriate to pass these predictions into an evaluation metric. Can someone explain what does it mean? If this gives estimate of Y (y prediction) for every Y (true Y), why can't I calculate metrics such as RMSE or coefficient of determination using these results? python scikit-learn cross-validation share | improve this question edited Nov 28 '18 at 17:52 desertnaut 20.3k 7 43 79 ...
