org.apache.jasper.JasperException: PWC6033: Unable to compile class for JSP

[gliderguy]

I have had a problem accessing the site http://localhost:9090 after running mvn jetty:run in the gameoflife-web directory. I get the exception below. I have tried running this project on a windows 7 machine and on an ubuntu/ mint 17.2 vm. I get the same problem in both environments. Any help would be appreciated.

Jetty starts up with
[INFO] Started [email protected]:9090
[INFO] Started Jetty Server
[INFO] Starting scanner at interval of 10 seconds.

when I access http://localhost:9090 I get the following:

I didn't dig into it but the versioning in the jsp files is the culprit. If you just need to get it running, remove it (from each file) as follows:

--- a/gameoflife-web/src/main/webapp/WEB-INF/jsp/home.jsp
+++ b/gameoflife-web/src/main/webapp/WEB-INF/jsp/home.jsp
@@ -96,20 +96,5 @@
     <a href="${newGamePage}">New Game</a>
 </div>

-<%
-    InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("/system.properties");
-    Properties prop = new Properties();
-    String appVersion = "";
-    if (inputStream != null) {
-        try {
-            prop.load(inputStream);
-            appVersion = prop.getProperty("app.version");
-        } catch (IOException ioe) {
-            ioe.printStackTrace();

Guys, I'm getting the following error message whenever I try to open the page after running mvn jetty:run

HTTP ERROR 500

I have verified what @spudone has mentioned about the home.jsp files , Still no luck.

Any ideas please ?

Use the following code to replace jetty plugin part

 <plugin>
                <groupId>org.eclipse.jetty</groupId>
                <artifactId>jetty-maven-plugin</artifactId>
                <version>9.3.0.v20150612</version>
                <configuration>
                    <scanIntervalSeconds>10</scanIntervalSeconds>
                    <httpConnector>
                        <port>${jetty.port}</port>
                        <idleTimeout>60000</idleTimeout>
                    </httpConnector>
                    <stopKey>foo</stopKey>
                    <stopPort>${jetty.stop.port}</stopPort>
                </configuration>
            </plugin>

@nickksun 's suggestion fixed it for me.

[zhangzui]

this config solved my problem!!! jetty version
org.eclipse.jetty
