Glassfish Embedded Server Mode Doesn't Works out of Internet
The First Problem: Without Internet
Using Glassfish 3.0.1 Embedded, while I was without Internet, I got the following error while starting the GF3 Embedded server:Aug 1, 2010 8:32:18 PM org.apache.catalina.core.StandardContext callServletContainerInitializers

I google the error and I found the following references to it:

The Diagnostic
The GF uses a special version (different from the used by Tomcat 5 or 6) of the class org.apache.jasper.xmlparser.ParserUtils and it (locally) "caches" the dtd and schemas files used by the Jasper version of the GF JSP 2.1. If you have installed GlassFish 3 you will find this DTD and schemas files at: \gf3-installation-dir\glassfish\lib\dtds and \gf3-installation-dir\glassfish\lib\schemas. This files isn't into GF Embedded version package glassfish-embedded-all-3.0.1.jar, neither glassfish-embedded-web-3.0.1.jar. So you will to deploy it with GF Embedded Server or accept to download it from the Internet as always is happens with the GF Embedded version. But if you try to put this schemas files with your server, don't matter where you try, nevertheless it doesn't work. So, why?
At runtime I inspected the program putting a breakpoint in the throwing error point at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177) and using Netbeans I saw that the environment of ParserUtils was:

Take a look again at:
CACHED_SCHEMA_RESOURCE_PATHS "file:/E:/embedded-glassfish/domains/lib/schemasweb-jsptaglibrary_2_0.xsd" "file:/E:/embedded-glassfish/domains/lib/schemasweb-jsptaglibrary_2_1.xsd" "file:/E:/embedded-glassfish/domains/lib/schemasweb-app_2_4.xsd" "file:/E:/embedded-glassfish/domains/lib/schemasweb-app_2_5.xsd"Saw? The filenames is wrong! The
CACHED_SCHEMA_RESOURCE_PATHS variable is from ParserUtils and also schemaResourcePrefix that contains the value "file:/E:/embedded-glassfish/domains/lib/schemas". The value is correct, but this variable is a String type. So, I thought the error was in the code: probably the programmer was concatenating this string with the schema filename.
I download the source code (not exactly the same source code used by the GF3, but it helped) of the ParserUtils used by the GF3 Embedded server and I found that there are at less two important variables that regulates where lives the local schema files: schemaResourcePrefix and dtdResourcePrefix. So we must find who is setting this variable. Looking at the source code, I found the method public static void setDtdResourcePrefix(String prefix) and:
146 /** 147 * Sets the path prefix for .xsd resources 148 */ 149 public static void setSchemaResourcePrefix(String prefix) { 150 151 schemaResourcePrefix = prefix; 152 153 for (int i=0; i<CACHED_SCHEMA_RESOURCE_PATHS.length; i++) { 154 String path = CACHED_SCHEMA_RESOURCE_PATHS[i]; 155 int index = path.lastIndexOf('/'); 156 if (index != -1) { 157 CACHED_SCHEMA_RESOURCE_PATHS[i] = 158 prefix + path.substring(index+1); 159 } 160 } 161 } 162
After investigating who is calling these methods, I found it: com.sun.enterprise.web.WebContainer! See:
409 // TODO: ParserUtils should become a @Service and it should initialize itself. 410 // TODO: there should be only one EntityResolver for both DigesterFactory 411 // and ParserUtils 412 File root = _serverContext.getInstallRoot(); 413 File libRoot = new File(root, "lib"); 414 File schemas = new File(libRoot, "schemas"); 415 File dtds = new File(libRoot, "dtds"); 416 417 try { 418 ParserUtils.setSchemaResourcePrefix(schemas.toURI().toURL().toString()); 419 ParserUtils.setDtdResourcePrefix(dtds.toURI().toURL().toString()); 420 ParserUtils.setEntityResolver(habitat.getComponent(EntityResolver.class, "web")); 421 } catch(MalformedURLException e) { 422 _logger.log(Level.SEVERE, "webContainer.exceptionSetSchemasDtdsLocation", e); 423 } 424
The Solution
So I just patched it adding a back slash to these path values. But thinking better, the error is in ParserUtils, because it must checks for the backslash and will add it if needed. But as I don't have the correct source code of ParserUtils (Guys, I hate Maven!!! What is wrong with Ant?!! Is it a new way to hide the things? What about is going with the open nature of the open source code? Oracle, IBM, are you listenning me?), I patched the WebContainer to:
412 File root = _serverContext.getInstallRoot(); 413 File libRoot = new File(root, "lib"); 414 File schemas = new File(libRoot, "schemas"); 415 File dtds = new File(libRoot, "dtds"); 416 417 try {418 ParserUtils.setSchemaResourcePrefix(schemas.toURI().toURL().toString() + "/"); 419 ParserUtils.setDtdResourcePrefix(dtds.toURI().toURL().toString() + "/");420 ParserUtils.setEntityResolver(habitat.getComponent(EntityResolver.class, "web")); 421 } catch(MalformedURLException e) { 422 _logger.log(Level.SEVERE, "webContainer.exceptionSetSchemasDtdsLocation", e); 423 } 424
To apply it, copy the WebContainer code, change it with the patch above and compile it using the glassfish-embedded-all-3.0.1.jar. Adds it to your project as a library and reference it before start the server (I just use String.valueOf(WebContainer.DISPATCHER_MAX_DEPTH) to forces the JVM to load and init my patched WebContainer class before to start the GF thinks).
Putting the Schemas
After having your webcontainer patched, copy the dtd and xml schemas from your standard glassfish installation to the directory that you setted as your install root to the GF3 Embedded.
This directory is there that was specified while building your GF3 Embedded using the method EmbeddedFileSystem.Builder.installRoot. If you don't use installRoot, check it using org.glassfish.api.embedded.Server.getServer("YourServerName").getFileSystem().installRoot. I didn't use installRoot method, but only the EmbeddedFileSystem.Builder.instanceRoot and GF3 Embedded understand as been its instal root directory there bellow that I specified to instanceRoot method. So my dtd and schemas files must be putted into: E:\embedded-glassfish\domains\lib because I tell to instanceRoot that to use the directory E:\embedded-glassfish\domains\domain1 to put my GF Embedded temporary domain. So, finally, I just copied both directories dtds and schemas to E:\embedded-glassfish\domains\lib as seen in the picture. Remember to copy this files when creating a new install root directory to your GF3Embedded server (maybe including when creating a new gf3e domain to it).
A better way to deal with theses files
Instead a better solution is to copy the xml schemas to your own WebContainer patched project. So the patch changes to:
412 File root = _serverContext.getInstallRoot(); 413 File libRoot = new File(root, "lib"); 414 java.net.URL schemas = getClass().getResource("/res/lib/schemas"); 415 java.net.URL dtds = getClass().getResource("/res/lib/dtds"); 416 417 //try { 418 ParserUtils.setSchemaResourcePrefix(schemas.toString() + "/"); 419 ParserUtils.setDtdResourcePrefix(dtds.toString() + "/"); 420 ParserUtils.setEntityResolver(habitat.getComponent(EntityResolver.class, "web")); 421 //} catch(MalformedURLException e) { 422 // _logger.log(Level.SEVERE, "webContainer.exceptionSetSchemasDtdsLocation", e); 423 //} 424
Now we get the dtds and schemas from our WebContainer pached jar file and then we don't need to copy this files while building our GFServer install root.
The Second Problem
Somebody isn't doing the job as we like... Another problem with Embedded GF lives with System.getProperty(INSTALL_ROOT_PROPERTY). As seen at com.sun.enterprise.deployment.node.SaxParserHandlerFactory it must be setted to our Embedded GF3 directory... But in my case it is setted to E:\embedded-glassfish\domains\domain1 - it's my instance root, my domain root, not my gf3 embedded install root... it's sad! And to ilustrate my vision this crazy world called gf embedded, see from the words of Sun's guys:
1 public static SaxParserHandler newInstance() { 2 SaxParserHandler result = null; 3 4 /* 5 *If the property com.sun.aas.installRoot is defined, use the 6 *original implementation (SaxParserHandler) which fetches DTDs and 7 *schemas from the installation directory tree. Otherwise, assume that 8 *the app client container is running under Java Web Start. In that 9 *case, there is no product installation directory (at least none can 10 *be assumed). The DTDs and schemas will be retrieved from the 11 *JWS-specific jar file instead (SaxParserHandlerBundled). 12 * 13 *bnevins, Oct 16, 2008. On Oct. 8, 2008 installRoot was changed to be setup 14 *earlier in the startup. As a result, Embedded GF broke. It sets up a fake installRoot, 15 *because there is *no* install-root. 16 *Improvement: don't just see if installRoot is set -- make sure installRoot 17 *is bonafide. 18 */ 19 20 if(installRootIsValid()) 21 result = new SaxParserHandler(); 22 else 23 result = new SaxParserHandlerBundled(); 24 25 return result; 26 } 27 28 private static boolean installRootIsValid() { 29 // In the context of this class, we need to make sure that we know if we 30 //have a route to local DTDs. Period. 31 32 String ir = System.getProperty(INSTALL_ROOT_PROPERTY); 33 34 if(!ok(ir)) 35 return false; 36 37 File dtds = new File(new File(ir), "lib/dtds"); 38 39 if(!dtds.isDirectory()) 40 return false; 41 42 return true; 43 } 44 45 private static boolean ok(String ir) { 46 return ir != null && ir.length() > 0; 47 } 48
Notes that expects to find a directory called lib/dtds into our install root directory. So, again we can put theses files or we can change the world... And, I say:
- Hey, there is a stupid hero here, call me!
So, from the first problem until now, after several hours, there are more two jobs to do:
- Fix the system property INSTALL_ROOT_PROPERTY to the correct gf embedded install root directory and ask to another traps appears..
But if we set it to the correct directory, the SaxParserHandlerBundled doesn't works anymore... - Change my first solution copying the dtds and schemas to the /dtds and /schemas from the our jar with the patches.
To do it, we must fix (break the broken code to tell truthly) the SaxParserHandlerFactory to always call SaxParserHandlerBundled. Then the solution is:
1 private static boolean ok(String ir) { 2 return "is world perfect?".equals(Boolean.TRUE.toString()); 3 } 4And now, after changed the dtds/schemas to lives into the root of the our jar, and change the first solution to use it from this new place, I really want that it works... let me try.
Bad. I back... having bad news: org.glassfish.web.WebEntityResolver is the guy that looks for dtds and schemas into the install root directory. So, or we use the first version of our WebContainer that just append the backslash to the path of dtds and schemas to pass it to ParserUtils or, again, we change the world!
So, back again, after spending a precious time from my current project (my deadline is near dead...), I change WebContainer to use instance of a new EntityResolver capable to do the work that we expected. Also, I need to rewrite the SaxParserHandler supplied by the SaxParserHandlerFactory to work as neeeded.
A Hard Work, but now It Works
Yeah, the GF3 Embedded works without internet now! But it was too hard to fix.. and to remember, the files that I changed or created, was:

The Patch
If you prefer, I put the download bellow to simplifier your work:- Zip with Sources and compiled jar: Netbeans Project
Reference it in your project before theglassfish-embedded-all-3.0.1.jar. - Compiled jar: Just the library that you need to refer
Use it together with theglassfish-embedded-all-3.0.1.jararchive.
I will go back to my work for now. Bye.
Ps.: Oracle, feel free to pay me for the time that I expended to fix it. I lost more than 15 precious hours of work devoted to resolve this.
Labels: development, it, java, tips, web

Worked brilliantly.
Thank you, your worked saved me a lot of time.
Good explaination.
I had the smae problem. I am using embedded galssfish in maven.
I had the issue because I am behid a proxy. for some reason the proxy details in settings.xml dont get passed to glassfish.
Any way I just added proxy host and port jvm parameters, while executing glassfish run target in maven, and it all worked.
mvn -Dhttp.proxyHost=webproxy -Dhttp.proxyPort=80 embedded-glassfish:run
