terminating: libs to export not found on above classpath: /sikulixlibs/windows/libs64

I am writing sikuli scripts in Eclipse..
I have added sikulixapi-1.1.0.jar and sikuli-3.0.0 in Eclipse Project build path.
I am getting following error:
*** classpath dump end
[error] RunTimeINIT: *** terminating: libs to export not found on above classpath: /sikulixlibs/windows/libs64
Picked up _JAVA_OPTIONS: -Xmx512M
I have added folderpath where the jar is there, i have added in Environment Variable as Path
How to resolve this issue?
Here is my code..

You have to double click the .jar.
There's a setup over there. I selected pack 2 and 3.

1.Download this jar file, https://mvnrepository.com/artifact/org.sikuli/SikuliX-Setup/1.1.0
Double click and select your options
I will generate sikulixapi.jar and sikulilibswin-1.1.0
link those jars with java build path -> classpath.
Ctrl+B build all
I hope your issues has been solved.

For people who do not have the solution of our partner alansiqueira27 (that my example), they should be downloaded directly,
sikulixlibswin-1.1.1.jar (last version windows)
with these lib should not have problems in windows and that is the link:

URI Schema: Infinite command prompts are opening

I went through the following doc center and tried to create my own URI schema myDocs:
https://msdn.microsoft.com/en-us/library/aa767914(v=vs.85).aspx
Following is my Java program. It takes a command line argument and returns the URL in the browser.
import java.awt.Desktop;
import java.io.IOException;
public class URIOpen {
public static void main(String args[]) {
if (args.length == 0) {
return;
}
String uri = args[0];
try {
Desktop.getDesktop().browse(java.net.URI.create(uri));
} catch (IOException e) {
System.out.println(e.getMessage());
}
}
}
I updated the (Default) value field of the command key like below.
"C:\Program Files (x86)\Java\jdk1.8.0_102\bin\java" -cp "C:\Users\Krishna\Documents\Study\Miscellaneous\examples" "URIOpen" "%1"
When I try to run the command myDocs:http://google.com, I end up opening infinite command prompts.
The following is my URI schema entry structure in the registry. Any help on this?

Your solution end up opening infinite command prompts because of:
you registered the execution of the custom URIOpen class to be activated by the system when it has to deal with myDocs:'s scheme based URI;
when custom URIOpen class executes the line Desktop.getDesktop().browse(java.net.URI.create(uri)); the system will receive again an URI based on the same scheme ( myDocs: ) and it will activate again a new command to execute your class again and again and again ...
Probably you would like to change your code in someway like that:
try {
java.net.URI theURI = java.net.URI.create(uri);
// System.out.println(theURI.getScheme()); => myDocs
String uriBrowsablePart = theURI.getRawSchemeSpecificPart();
// System.out.println(uriBrowsablePart); => http://google.com
Desktop.getDesktop().browse(java.net.URI.create(uriBrowsablePart));
// the above statement will open default browser on http://google.com
} catch (IOException e) {
System.out.println(e.getMessage());
}
try replacing your try-catch block with my suggestion and see if it works as required.

How to get version attribute from a gradle build to be included in runtime Swing application

I have a simple parent project with modules/applications within it. My build tool of choice is gradle. The parent build.gradle is defined below.
apply plugin: 'groovy'
dependencies {
compile gradleApi()
compile localGroovy()
}
allprojects {
repositories {
mavenCentral()
}
version "0.1.0-SNAPSHOT"
}
What I would like to do is utilize the version attribute (0.1.0-SNAPSHOT) within my swing application. Specifically, I'd like it to display in the titlebar of the main JFrame. I expect to be able to do something like this.setTitle("My Application - v." + ???.version);
The application is a plain java project, but I'm not opposed to adding groovy support it it will help.

I like creating a properties file during the build. Here's a way to do that from Gradle directly:
task createProperties(dependsOn: processResources) {
doLast {
new File("$buildDir/resources/main/version.properties").withWriter { w ->
Properties p = new Properties()
p['version'] = project.version.toString()
p.store w, null
}
}
}
classes {
dependsOn createProperties
}

You can always use brute force as somebody suggested and generate properties file during build. More elegant answer, which works only partially would be to use
getClass().getPackage().getImplementationVersion()
Problem is that this will work only if you run your application from generated jar - if you run it directly from IDE/expanded classes, getPackage above will return null. It is good enough for many cases - just display 'DEVELOPMENT' if you run from IDE(geting null package) and will work for actual client deployments.

Better idea is to keep the project version in gradle.properties file. All the properties from this file will be automatically loaded and can be used in build.gradle script.
Then if you need the version in your swing application, add a version.properties file under src/main/resources folder and filter this file during application build, here is a post that shows how it should be done.
version.properties will be included in the final jar, hence can be read and via ClassLoader and properties from this file can be displayed in application.

Simpler and updated solution of #Craig Trader (ready for Gradle 4.0/5.0)
task createProperties {
doLast {
def version = project.version.toString()
def file = new File("$buildDir/resources/main/version.txt")
file.write(version)
}
}
war {
dependsOn createProperties
}

I used #Craig Trader's answer, but had to add quite some changes to make it work (it also adds git-details):
task createProperties() {
doLast {
def details = versionDetails()
new File("$buildDir/resources/main/version.properties").withWriter { w ->
Properties p = new Properties()
p['version'] = project.version.toString()
p['gitLastTag'] = details.lastTag
p['gitCommitDistance'] = details.commitDistance.toString()
p['gitHash'] = details.gitHash.toString()
p['gitHashFull'] = details.gitHashFull.toString() // full 40-character Git commit hash
p['gitBranchName'] = details.branchName // is null if the repository in detached HEAD mode
p['gitIsCleanTag'] = details.isCleanTag.toString()
p.store w, null
}
// copy needed, otherwise the bean VersionController can't load the file at startup when running complete-app tests.
copy {
from "$buildDir/resources/main/version.properties"
into "bin/main/"
}
}
}
classes {
dependsOn createProperties
}
And load it from the constructor of class: VersionController
import static net.logstash.logback.argument.StructuredArguments.v;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.info.BuildProperties;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Map;
import java.util.Properties;
import java.util.Set;
#RestController
public class VersionController {
final static Logger log = LoggerFactory.getLogger(AppInfoController.class);
private Properties versionProperties = new Properties();
private String gitLastTag;
private String gitHash;
private String gitBranchName;
private String gitIsCleanTag;
VersionController()
{
String AllGitVersionProperties = "";
InputStream inputStream = getClass().getClassLoader().getResourceAsStream("classpath:/version.properties");
if(inputStream == null)
{
// When running unit tests, no jar is built, so we load a copy of the file that we saved during build.gradle.
// Possibly this also is the case during debugging, therefore we save in bin/main instead of bin/test.
try {
inputStream = new FileInputStream("bin/main/version.properties");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
try {
versionProperties.load(inputStream);
} catch (IOException e) {
AllGitVersionProperties += e.getMessage()+":";
log.error("Could not load classpath:/version.properties",e);
}
gitLastTag = versionProperties.getProperty("gitLastTag","last-tag-not-found");
gitHash = versionProperties.getProperty("gitHash","git-hash-not-found");
gitBranchName = versionProperties.getProperty("gitBranchName","git-branch-name-not-found");
gitIsCleanTag = versionProperties.getProperty("gitIsCleanTag","git-isCleanTag-not-found");
Set<Map.Entry<Object, Object>> mainPropertiesSet = versionProperties.entrySet();
for(Map.Entry oneEntry : mainPropertiesSet){
AllGitVersionProperties += "+" + oneEntry.getKey()+":"+oneEntry.getValue();
}
log.info("All Git Version-Properties:",v("GitVersionProperties", AllGitVersionProperties));
}
}

Using #Craig Trader's solution to save the properties in a version.properties file. Add to build.gradle:
task createProperties() {
doLast {
def details = versionDetails()
new File("$buildDir/resources/main/version.properties").withWriter { w ->
Properties p = new Properties()
p['version'] = project.version.toString()
p['gitLastTag'] = details.lastTag
p['gitCommitDistance'] = details.commitDistance.toString()
p['gitHash'] = details.gitHash.toString()
p['gitHashFull'] = details.gitHashFull.toString() // full 40-character Git commit hash
p['gitBranchName'] = details.branchName // is null if the repository in detached HEAD mode
p['gitIsCleanTag'] = details.isCleanTag.toString()
p.store w, null
}
// copy needed, otherwise the bean VersionController can't load the file at startup when running complete-app tests.
copy {
from "$buildDir/resources/main/version.properties"
into "bin/main/"
}
}
}
classes {
dependsOn createProperties
}
To load the properties runtime in version.properties you need to annotate your class with #PropertySource({"classpath:version.properties"})
Then you can assign a property to a private variable with annotation like:
#Value("${gitLastTag}")
private String gitLastTag;
Full example:
package com.versioncontroller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
import javax.annotation.PostConstruct;
import java.util.Properties;
#PropertySource({"classpath:version.properties"})
public class VersionController {
#Value("${gitLastTag}")
private String gitLastTag;
#Value("${gitHash}")
private String gitHash;
#Value("${gitBranchName}")
private String gitBranchName;
#Value("${gitIsCleanTag}")
private String gitIsCleanTag;
#PostConstruct // properties are only set after the constructor has run
private void logVersion(){
// when called during the constructor, all values are null.
System.out.println("All Git Version-Properties:");
System.out.println("gitLastTag: " + gitLastTag),
System.out.println("gitHash: " + gitHash),
System.out.println("gitBranchName: " + gitBranchName),
System.out.println("gitIsCleanTag: " + gitIsCleanTag));
}
}

Extracting Text From JPG

I've tried this code and added the needed jar files but still I'm getting an error message like Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'libtesseract302'.
Is there a complete tutorial how to extract text and what things should be done to address the error? Any help is appreciated...
import net.sourceforge.tess4j.*;
import java.io.File;
public class ExtractTxtFromImg {
public static void main(String[] args) {
File imgFile = new File("C:\\Documents and Settings\\rueca\\Desktop\\sampleImg.jpg");
Tesseract instance = Tesseract.getInstance(); // JNA Interface Mapping
// Tesseract1 instance = new Tesseract1(); // JNA Direct Mapping
try {
String result = instance.doOCR(imgFile);
System.out.println(result);
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
}

In addition to adding the jars, you also need to add the natives. You can do so with Djava.library.path="C:\[absolute path to dir containing *.dll files and such]"
Note that you need to provide the directory, not the file itself.

Java running in Oracle - the imported jars

I am trying to get a small java class to load into Oracle 11g so I can run it and call it from PL/SQL. I coded and compiled the class on my local machine in eclipse and it compiles fine. I packaged it up into a jar (with the other jar files it depends on in the jar). They I tried loading my jar into Oracle 11g. Everything loads in, unfortunately when it loads my custom java class, it stays invalid and when I try to compile it within Oracle it says it can't find references to the classes (the ones I had packaged in my jar with my class).
Is there some other sort of setting I need to configure?
Here is what my custom classes code looks like:
import com.flashline.registry.openapi.base.OpenAPIException;
import com.flashline.registry.openapi.entity.*;
import com.flashline.registry.openapi.service.v300.FlashlineRegistry;
import com.flashline.registry.openapi.service.v300.FlashlineRegistryServiceLocator;
import javax.xml.rpc.ServiceException;
import java.net.URL;
import java.rmi.RemoteException;
import org.apache.log4j.Logger;
import java.net.MalformedURLException;
public class AssetExtractor {
/**
* #param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
}
static Logger LOG;
static AuthToken authToken = null;
static FlashlineRegistry repository = null;
static URL repoURL;
public static FlashlineRegistry getRepository()
{
if(repository == null)
try
{
try{
repoURL = new URL("https://myserver/oer/services/FlashlineRegistry");
}catch(MalformedURLException mue)
{
LOG.error(mue);
}
repository = (new FlashlineRegistryServiceLocator()).getFlashlineRegistry(repoURL);
LOG.debug((new StringBuilder()).append("Created repository at URL=").append(repoURL.toString()).toString());
}
catch(ServiceException e)
{
LOG.error(e, e);
}
return repository;
}
public static AuthToken getAuthToken()
{
if(authToken == null)
try
{
authToken = getRepository().authTokenCreate("user", "password");
LOG.debug("Created auth token.");
}
catch(OpenAPIException e)
{
LOG.error(e, e);
}
catch(RemoteException e)
{
LOG.error(e, e);
}
else
try
{
getRepository().authTokenValidate(authToken);
}
catch(OpenAPIException e)
{
LOG.info("Auth token was invalid. Recreating auth token");
authToken = null;
return getAuthToken();
}
catch(RemoteException re)
{
LOG.error("Remote exception occured during creation of suth token after determined to be invalid", re);
re.printStackTrace();
authToken = null;
}
return authToken;
}
public static String getAssetXML(String strAssetID)
{
String strAsset = null;
try
{
strAsset = getRepository().assetReadXml(getAuthToken(), Long.parseLong(strAssetID));
}
catch(OpenAPIException e)
{
e.printStackTrace();
}
catch(RemoteException e)
{
e.printStackTrace();
}
return strAsset;
}
}
And all the *.jar files for the imports are inside my AssetExtractor.jar
The command I've been using to load the jar into oracle is:
loadjava -v -f -resolve -resolver "((* OER) (* PUBLIC))" -user oer/***** AssetExtractor.jar
Any ideas would be helpful!

So it appears that if I do the following it solves nearly all my problems:
Edit the Oracle users' .profile to SET and EXPORT the CLASSPATH, PATH, LD_LIBRARY_PATH, ORACLE_HOME, JAVA_HOME with the correct paths
SQLPlus as sys as sysdba
EXEC dbms_java.grant_permission( 'OER', 'SYS:java.util.PropertyPermission', 'java.class.path', 'write' );
OS Commandline as oracle user:
loadjava –v –grant PUBLIC <jar> -user oer/****** for all jars
SQLPlus as OER user
DECLARE
v_classpath VARCHAR2(4000);
v_path VARCHAR2(4000);
BEGIN
v_classpath := DBMS_JAVA.set_property('java.class.path', '/opt/oracle/102/jdk/lib:/mnt/hgfs/vmshare/rex_lib/aler-axis- 1.2.1.jar:/mnt/hgfs/vmshare/rex_lib/aler-axis-jaxrpc-1.2.1.jar:/mnt/hgfs/vmshare/rex_lib/client.rex- 11.1.1.5.0.jar:/mnt/hgfs/vmshare/rex_lib/commons-httpclient-3.0rc2- flashline.jar:/mnt/hgfs/vmshare/rex_lib/log4j-1.2.8.jar');
v_path := DBMS_JAVA.set_property('java.path', '/opt/oracle/102/jdk/bin');
END;
/
alter java source "AssetExtractor" compile;
show errors
The only outstanding issue is that for some reason it still can't locate/resolve some of the Oracle OER classes (which should all be in the client.rex*.jar, I opened and saw them there. If I can solve this part then I'm good to go.
