![]() APAR status Closed as program error. Error description This APAR is for the propose of obtaining performance improvements in the JspBatchCompiler.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server developers * * utilizing the JSPBatchCompiler at deploy * * time. * **************************************************************** * PROBLEM DESCRIPTION: JSPBatchCompiler compilation takes * * hours to complete war files that * * contain a large number of JSPs. * **************************************************************** * RECOMMENDATION: * **************************************************************** Customers are advised to batch compile JSPs at deploy time. If a Web Application Archive contains a large number of JSPs, the compilation process creates a large number of javac compiler objects (one per jsp) for compiling thus degrading performance.Problem conclusion Modified the JSPBatchCompiler to create only one compiler per directory in a WAR file. This improved performance without changing the underlying batch compilation process. The new process will first parse the directory of JSPs and then compile the list of parsed JSPs.Temporary fix Comments
