java - URL.openStream throws an error -

please me resolve issue, trying write code generate pdf using apache fop. have developed xsl-fo, in resource folder of application i.e src/main/resource. when testing through junit working fine, when try application getting issue.

problem see @ url.openstream when trying application, path duplicated, when accessed junit working good.

technology stack jdk : 1.7 spring : 4.1.5

please me resolve issue

first, jb nizet stated, should not use url or file reading template. don't need either of those; need read packaged resource inputstream:

try (inputstream xslstream = getclass().getresourceasstream("/" + templatefile)) {     streamsource transformsource = new streamsource(xslstream); 

second, class.getresource , class.getresourceasstream methods (and classloader equivalents) require a string argument containing forward slashes (/), on platforms, windows.

so either change calling code passes "xsltemplate/summary.xsl", or put @ beginning of method:

templatefile = templatefile.replace('\\', '/');
