neo4j - graphaware plugins - plugins

I downloaded the plugins of graphaware nlp,open-nlp,framework and copied the jar files to the plugins directory.
And as per the steps in neo4j , i included the following lines in neo4j.config file
dbms.unmanaged_extension_classes=com.graphaware.server=/graphaware
com.graphaware.runtime.enabled=true
com.graphaware.module.NLP.2=com.graphaware.nlp.module.NLPBootstrapper
After inserting this the localhost:7474 is not starting.
But when i comment these lines localhost starts and works properly but doesnt include the plugins.
Version : enterprise 3.1.3
Error in LocalLost after commenting those lines:

please help me out


You do not have sufficient memory for the NLP plugins to load, hence the NLP module is not registered and thus not available once that database has started.
As stated in the NLP plugin README, you need at least 4GB of heap for the modules to run, adapt it in your neo4j.conf and restart.

Tomcat 9.0.52 crashes with "java.util.zip.ZipException: invalid LOC header (bad signature)" when started in debug mode - any work-around?

When trying to start Tomcat (9.0.52) in debug mode ("Debug on Server") from Eclipse (v2020-12 (4.18.0) / Build id: 20201210-1552) I get the following error (see full stacktrace further below):

While the reasons seems clear - there is some issue reading a .jar file - the question I have is:
How can I find out, WHICH .jar is causing this issue? Is there some option to get more info on the root cause: which library (either from Tomcat or which application-jar?) that it tries to read is causing this?
The odd thing is: When I start this up in normal "run" mode in Eclipse or as a Windows Service, then Tomcat as well as the application start up fine. This zip-file problem only happens when I try to start it in debug mode! And - when starting Tomcat from Eclipse - then no .war-file is created but rather Tomcat's classpath is adjusted such, that the class files are used in-situ (i.e. directly from the target directory where they have been compiled to). So there is no additional .jar file created compared to the non-debug mode (which is why I am puzzled why this happens only in debug mode).
Eclipse uses Java 14 (if I am correct) but is configured to compile to 1.8 compatibility and the runtime (i.e. Tomcat and our application) uses Java 1.8 (I have installed the "almost latest" AdoptOpenJDK v1.8 / jdk-8.0.292.10-hotspot).
Tomcat's download page (https://tomcat.apache.org/whichversion.html) claims, that Tomcat 9.0.52 runs with Java "8 and later", so IMHO I should be OK in terms of prereq's.
Any idea how to get the above setup starting up/working in debug mode?

Later addition: I also tried the entire setup using a Java 11 VM for Tomcat but with the same result. So, this issue with some .jar-file having an invalid header or signature is apparently NOT a Java<=(1.)8 vs. Java >=v9 issue. So I reverted back to Java 1.8.

A day later:
This morning when I tried to restart Tomcat again in debug mode to investigate further, the server started up! No more .zip-file issues! The problem just vanished... :-)
Thanks to all who responded!

Weblogic 12C error java.lang.ClassNotFoundException: weblogic.jms.common.ResourceAllocationException

I am facing this issue on my WebLogic 12 C, where an application gives this error
java.lang.ClassNotFoundException: weblogic.jms.common.ResourceAllocationException
The jar for the above class is wlclient.jar and it's not included in my application and I checked the managed server classpath ,it's not included there as well.
Funny thing is if I try adding the wlclient.jar in the setDomainEnv.sh as PRE_CLASSPATH hoping it will pick up the jar , I get the below error and managed server fails to start

I found if I add the classpath fully like below then the managed server gave error on startup
,
PRE_CLASSPATH="${DOMAIN_HOME}/lib/wlclient.jar"
export PRE_CLASSPATH
But if I add the classpath as below , then it worked.
PRE_CLASSPATH="${DOMAIN_HOME}/lib/"
export PRE_CLASSPATH

To connect with JVisualVM to JBoss, you need to add the jboss-cli-client.jar to the classpath:
$JAVA_HOME/bin/jvisualvm -cp:a $JBOSS_HOME/bin/client/jboss-cli-client.jar
If this jar is not available in your EAP version, then you must add the following modules under $JBOSS_HOME/modules to the classpath:
org/jboss/remoting3/remoting-jmx org/jboss/remoting3 org/jboss/logging org/jboss/xnio org/jboss/xnio/nio org/jboss/sasl org/jboss/marshalling org/jboss/marshalling/river org/jboss/as/cli org/jboss/staxmapper org/jboss/as/protocol org/jboss/dmr org/jboss/as/controller-client org/jboss/threads org/jboss/as/controller
This blog post has a script that you can be used for that. If you are registered customer, you can also download a script here.

Sqoop installation export and import from postgresql

I v'e just installed sqoop and was testing it . I tried to export some data from hdfs to postgresql using sqoop. When I run it it throws the following exception : java.io.IOException: Can't export data, please check task tracker logs . I think there may also have been a problem in installation.

This is the posgres table:
Table "public.mysort"
Column | Type | Modifiers
--------+---------+-----------
name | text |
marks | integer |
The sqoop command is:
sqoop export --connect jdbc:postgresql://localhost/testdb --username akshay --password akshay --table mysort -m 1 --export-dir MySort/input
Followed by the error:

Any help in resolving the issue is appreciated.

Here is the complete procedure for installation and import and export commands for Sqoop. Hope fully it may be helpful to some one. This one is tried and tested by me and actually works.
Download : apache.mirrors.tds.net/sqoop/1.4.4/sqoop-1.4.4.bin__hadoop-2.0.4-alpha.tar.gz
sudo mv sqoop-1.4.4.bin__hadoop-2.0.4-alpha.tar.gz /usr/lib/sqoop
copy paste followingtwo lines in .bashrc
export SQOOP_HOME=/usr/lib/sqoop
export PATH=$PATH:$SQOOP_HOME/bin
Go to /usr/lib/sqoop/conf folder and copy sqoop-env-template.sh to new file sqoop-env.sh and modify export HADOOP_HOME ,HBASE_HOME,etc to the installation directory
Download the postgresql conector jar file from jdbc.postgresql.org/download/postgresql-9.3-1101.jdbc41.jar
create a directory manager.d in sqoop/conf/
create a file postgresql in conf/ and add the following line in it
org.postgresql.Driver=/usr/lib/sqoop/lib/postgresql-9.3-1101.jdbc41.jar
name the connector.jar file accordingly
For Export
Create a user in postgres:
createuser -P -s -e ace
Enter password for new role: ace
Enter it again: ace
CREATE DATABASE testdb OWNER ace TABLESPACE ace;
create table stud1(id int,name text);
Create a file student.txt
Add lines such as:
1,Ace
2,iloveapis
hadoop fs -put student.txt
sqoop export --connect jdbc:postgresql://localhost:5432/testdb --username ace --password ace --table stud1 -m 1 --export-dir student.txt
check in postgres: Select * from stud1;
For Import:
sqoop import --connect jdbc:postgresql://localhost:5432/testdb --username akshay --password akshay --table stud1 --m 1
hadoop fs -ls -R stud1
Expected Output:
-rw-r--r-- 1 hduser supergroup 0 2014-06-13 18:10 stud1/_SUCCESS
-rw-r--r-- 1 hduser supergroup 21 2014-06-13 18:10 stud1/part-m-00000
hadoop fs -cat stud1/part-m-00000
Expected Output:
1,Ace
2,iloveapis
hadoop fs -copyToLocal stud1/part-m-00000 $HOME/imported_data.txt
