JXLS Transformer object is not getting initialized

I am trying to use JXLS with my custom evaluator for Excel downloads, following this official page.
I have no clue why is it not providing me Transformer object. Trying to figure out from exceptions since a long time but unable to resolve it.
Excel:
Maven:
<dependency>
<groupId>org.jxls</groupId>
<artifactId>jxls</artifactId>
<version>2.4.3</version>
</dependency>
<dependency>
<groupId>org.jxls</groupId>
<artifactId>jxls-poi</artifactId>
<version>1.0.14</version>
</dependency>
Java:
InputStream is2 = new FileInputStream("C:/Users/User/Downloads/ExcelTest.xlsx");
OutputStream os = new FileOutputStream("C:/Users/User/Downloads/ExcelTest_Out.xlsx");
Transformer transformer = TransformerFactory.createTransformer(is2, os); // this throws error and returns null object
ExpressionEvaluator evaluator = new IMCScriptEvaluator(ctx);
transformer.getTransformationConfig().setExpressionEvaluator(evaluator);
Exception trace:

Multiple versions of same Apache POI dependency was creating an issue.
Internally JXLS also uses Apache POI, which was also explicitly added into the dependency of the project, which had version conflict.
Hence skipping the JXLS Apache-POI and upgrading existing one with latest (As per need of JXLS dependency) made it work.

GAE and Spring Social

I'm trying to connect my application to Google+.
I have:
Spring Social 1.1.4.RELEASE
Google App Engine 1.9.38 (for the frontend layer)
Tomcat v7.0 (for the backend layer)
When I try to authorize my google gmail credentials to access to the applcation,
Spring launchs this error:
HTTP ERROR 500
Problem accessing /connect/google. Reason:
java.net.ProxySelector is a restricted class. Please see the Google App Engine developer's guide for more details.
Caused by:
java.lang.NoClassDefFoundError: java.net.ProxySelector is a restricted class. Please see the Google App Engine developer's guide for more details.

I also see that the problem should be in this class: HttpClientBuilder.class.
In this part of code, we can see:
if (hostnameVerifier == null) {
hostnameVerifier = SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER;
}
if (sslcontext != null) {
sslSocketFactory = new SSLConnectionSocketFactory(
sslcontext, supportedProtocols, supportedCipherSuites, hostnameVerifier);
} else {
if (systemProperties) {
sslSocketFactory = new SSLConnectionSocketFactory(
(SSLSocketFactory) SSLSocketFactory.getDefault(),
supportedProtocols, supportedCipherSuites, hostnameVerifier);
} else {
sslSocketFactory = new SSLConnectionSocketFactory(
SSLContexts.createDefault(),
hostnameVerifier);
}
}
The problem is that i should set systemProperties as false
Is it possible to do this without override the class?

FtpRemoteFileTemplate checks if remote file exists but cannot retrieve it

I have a FtpRemoteFileTemplate:
#Autowired
private FtpRemoteFileTemplate ftpTemplate;
and I use it in this way:
if (ftpTemplate.exists(fileAbsPath)) {
return getRemoteFileAsByteArray(fileAbsPath);
}
where getRemoteFileAsByteArray is
private byte[] getRemoteFileAsByteArray(String absoluteFileName) {
return ftpTemplate.execute(session -> IOUtils.toByteArray(session.readRaw(absoluteFileName)));
}
The statement ftpTemplate.exists(fileAbsPath) works and correctly returns true, the ftpTemplate.execute(session -> IOUtils.toByteArray(session.readRaw(absoluteFileName))) after a while throws this exception:
org.springframework.messaging.MessagingException: Failed to execute on session; nested exception is java.io.IOException: Failed to obtain InputStream for remote file /xxx/xxx/foo.jpg: 425

From FileZilla I'm able to retreive the same file from the same computer.
Where I'm getting wrong?

FTP requires two separate channels for communication. The command channel is working for you as you are able to get the file existence status from the server. If you are trying a communication in Active mode, it requires the server to initiate a connection to your system and in that case chances are that your firewall will block such a connection, causing the IO exception.
To overcome this issue you can change the client mode to Passive. In config, change clientMode to 2. Or if you have hold of FTPClient instance, you can also use client.enterLocalPassiveMode();.
PASSIVE_LOCAL_DATA_CONNECTION_MODE = 2

GeoServer database failure while creating a 'CoordinateReferenceSystem' object for code "EPSG:4326"

you can solve this problem by this url
http://docs.geoserver.org/stable/en/user/advanced/crshandling/manualepsg.html
just remove the temp folder for geoserver

Remove the cached copy of the EPSG database, so that can be recreated. On Linux, the command is:
rm -rf /tmp/Geotools/Databases/HSQL
Restart GeoServer.
