> Hello,
> I would like to use tomcats virtual webapp functionality
> (http://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Virtual_webapp)
> in my mavenised struts application but there is an issue where it cannot find
> the struts.xml file. Basically using the virtual webbapp its adds
> alternative class folders where stuff comes from.
> ie project/src/main/webapp and project/target/classes;
> Basically its throwing a IllegalArgumentException
> com.opensymphony.xwork2.util.fs.DefaultFileManager when it cannot find the
> file project/src/main/webapp/WEB-INF/classes.
> <code>
> private InputStream openFile(URL fileUrl) {
> try {
> InputStream is = fileUrl.openStream();
> if (is == null) {
> throw new IllegalArgumentException("No file '" + fileUrl + "'
> found as a resource");
> }
> return is;
> } catch (IOException e) {
> throw new IllegalArgumentException("No file '" + fileUrl + "'
> found as a resource");
> }
> }
> </code>
> and then not checking the rest of the found resources in
> project/target/classes
> com.opensymphony.xwork2.config.providers.XmlConfigurationProvider
> <code>
> URL url = null;
> while (urls.hasNext()) {
> try {
> url = urls.next();
> is = fileManager.loadFile(url);
> InputSource in = new InputSource(is);
> in.setSystemId(url.toString());
> docs.add(DomHelper.parse(in, dtdMappings));
> } catch (XWorkException e) {
> if (includeElement != null) {
> throw new ConfigurationException("Unable to load " +
> url, e, includeElement);
> } else {
> throw new ConfigurationException("Unable to load " +
> url, e);
> }
> } catch (Exception e) {
> throw new ConfigurationException("Caught exception while
> loading file " + fileName, e, includeElement);
> } finally {
> if (is != null) {
> try {
> is.close();
> } catch (IOException e) {
> LOG.error("Unable to close input stream", e);
> }
> }
> }
> }
> <code>
> To make it work I modified above to:
> <code>
> // Catch the exception
> ConfigurationException theException = null;
> URL url = null;
> while (urls.hasNext()) {
> try {
> url = urls.next();
> is = fileManager.loadFile(url);
> InputSource in = new InputSource(is);
> in.setSystemId(url.toString());
> docs.add(DomHelper.parse(in, dtdMappings));
>
> theException = null;
>
> } catch (XWorkException e) {
> if (includeElement != null) {
> //throw new ConfigurationException("Unable to load "
> + url, e, includeElement);
> theException = new ConfigurationException("Unable to
> load " + url, e, includeElement);
> } else {
> //throw new ConfigurationException("Unable to load "
> + url, e);
> theException = new ConfigurationException("Unable to
> load " + url, e);
> }
> } catch (Exception e) {
> //throw new ConfigurationException("Caught exception
> while loading file " + fileName, e, includeElement);
> theException = new ConfigurationException("Caught
> exception while loading file " + fileName, e, includeElement);
> } finally {
> if (is != null) {
> try {
> is.close();
> } catch (IOException e) {
> LOG.error("Unable to close input stream", e);
> }
> }
> }
> }
>
> // OK bail out as resource not found
> if ( theException != null) {
> throw theException;
> }
> </code>
> ie try the rest of the files and then if not found give up and throw the
> exception.
