Another Post because I need this code snippet sometimes and don’t want to search the whole internet every time. The following code snippet opens the Manifest file an reads the Implementation properties:
public String getBuildVersion() { FacesContext facesContext = FacesContext.getCurrentInstance(); if (facesContext != null) { if (facesContext.getExternalContext().getContext() instanceof ServletContext) { ServletContext servletContext = (ServletContext) facesContext.getExternalContext().getContext(); if (servletContext != null) { Properties prop = new Properties(); try { prop.load(servletContext.getResourceAsStream("/META-INF/MANIFEST.MF")); } catch (IOException e) { String msg = "Could not read the MANIFEST.MF for getting the VersionInfo"; LOG.error(msg, e); return msg; } String implementationTitle = prop.getProperty("Implementation-Title"); String implementationVendor = prop.getProperty("Implementation-Vendor"); String implementationVersion = prop.getProperty("Implementation-Version"); return implementationTitle + " Build-Id:" + implementationVersion + " by:" + implementationVendor; } } } return "Unable to determine Softwareversion"; }
