So here is a snippet of bytecode which i am trying to verify using ASM's class Verifier:
public <init>(Ljava/io/InputStream;)V
ALOAD 0
ALOAD 1
SIPUSH 2048
NEW org/apache/xerces/impl/msg/XMLMessageFormatter
DUP
INVOKESPECIAL org/apache/xerces/impl/msg/XMLMessageFormatter.<init> ()V
INVOKESTATIC java/util/Locale.getDefault ()Ljava/util/Locale;
INVOKESPECIAL org/apache/xerces/impl/io/UTF8Reader.<init> (Ljava/io/InputStream;ILorg/apache/xerces/util/MessageFormatter;Ljava/util/Locale;)V
RETURN
MAXSTACK = 5
MAXLOCALS = 2
this is part of a larger class org/apache/xerces/impl/io/UTF8Reader. Now, when i run the the bytecode of this class through the Class verifier provided by ASM, I get the following results:
org.objectweb.asm.tree.analysis.AnalyzerException: **Error at instruction 7: java.lang.ClassNotFoundException: org.apache.xerces.util.MessageFormatter**

I am highly confused by this last bit... why is it giving out a ClassNotFound exception for the org/apache/xerces/util/MessageFormatter object at line 7?
Thanks.
ASM's verifier tool does check validity of each stack and variable slot as per JVM specification. One of the checks is that values in all variable and stack slots have the same types at merge points. So, this implementation loads classes to find common super types.

Please HELP me resolve this, I tried various ways of boot setup with aws lambda but failed every time. Please help me fix this or help me out in setting up in any other way. Thanks.
In your logs we can see :
NoClassDefFoundError: javax/servlet/ServletContainerInitializer
ClassNotFoundException: javax.servlet.ServletContainerInitializer
Could you please check if libs are loaded , there must be something missing and not loaded up correctly
Also, something like this has been done
<dependency>
<groupId>com.amazonaws.serverless</groupId>
<artifactId>aws-serverless-java-container-spring</artifactId>
<version>1.3.2</version>
</dependency>
Also double check steps in :
https://github.com/awslabs/aws-serverless-java-container/wiki/Quick-start---Spring-Boot
I had the same issue. I was using version 0.2 of aws-serverless-java-container-spring and had to switch to version 1.3.2 as the former version didn't have SpringBootLambdaContainerHandler class.

I use the lua script:
local lock = redis.call('get', KEYS[1])
if not lock then
return redis.call('SETEX', KEYS[1], ARGV[1] ,ARGV[2] );
end
return false
From spring boot application I use to call redis with the script
DefaultRedisScript<Boolean> redisScript = new
DefaultRedisScript<Boolean>();
redisScript.setScriptSource(new ResourceScriptSource(new ClassPathResource("checkandset2.lua")));
redisScript.setResultType(Boolean.class);
System.out.println(redisTemplate.execute(redisScript , Collections.singletonList("value123"),"10" ,"key123"));

any advice how can I pass expiry time value to the lua script?
I'm a newbie myself, and was having a similar problem. Try sending the string "10", instead of the Long. Worked for me.
The thread might be old, but might be helpful for others who might stumble upon this.
For me, the reason was using JdkSerializationRedisSerializer as value serializer, like: redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer()), this is also the default.
To fix this, see below the fix:
private static void redisEvalForExpire(String scriptText, List<String> keys, Object[] argv) {
// since spring boot serializes data to - "\xac\xed\x00\x05t\x00\x0" it was not being recognized by redis as integer
redisTemplate.execute(new DefaultRedisScript<>(scriptText), new StringRedisSerializer(), new StringRedisSerializer(), keys, argv);
}
This says use StringRedisSerializer for any value, so when we do - set a 2, using JdkSerializationRedisSerializer, 2 serialized to something like:
"\xac\xed\x00\x05sr\x00\x11java.lang.Integer\x12\xe2\xa0\xa4\xf7\x81\x878\x02\x00\x01I\x00\x05valuexr\x00\x10java.lang.Number\x86\xac\x95\x1d\x0b\x94\xe0\x8b\x02\x00\x00xp\x00\x00\x00\x02"
but when we say use StringRedisSerializer, 2 is sent as "2", which Redis can easily recognize.
Official Documentation
I am trying to write a standalone program that will be called by a bat file. I found something like a trust all certificate manager.
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
}
};
// Install the all-trusting trust manager
try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
URL url = new URL("--insert server url here--");
//url.openStream();
// URLConnection urlConnection = url.openConnection();
HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
} catch (MalformedURLException mfe) {
mfe.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
it works fine in my ide but after I built in and run it via the bat file it keeps giving me this error

am I doing something wrong? Should I sign a certificate in order to connect to the server?
Have found the answer for the problem above, will need to include the sunjce_provider.jar into the lib folder of the standalone program.
